EXAMINING FUND BALANCE IN MICHIGAN SCHOOL DISTRICTS By Zainin Bidin A DISSERTATION Submitted to Michigan State University in partial of the requirements for the degree of DOCTOR OF PHILOSOPHY K-12 Educational Administration 2012 ABSTRACT EXAMINING FUND BALANCE IN MICHIGAN SCHOOL DISTRICTS By Zainin Bidin This research examines the financial profiles of 550 public school districts in Michigan and highlights the association between school district fund balance and the following eleven indicators: enrollment, percent enrollment change, percent of students receive free and reduced lunch (FRL), percent of special education students, percent of English Language Learners (ELL), per pupil foundation allowance, urban, property taxable value, pupil-teacher ratio, average teacher salary, and business and administrative expenses as a percentage of current operating expenditures from fiscal year 2001 to 2010. School districts financial profiles display a rising number of districts in financial deficit and near deficit, which is defined as fiscal stress in this study. Throughout the years, the mean of the district fund balance has steadily declined, and the movement of school districts in and out of deficit and fiscal stress has been unpredictable. Utilizing pooled regression analysis, an investigation was conducted to reveal the positive and negative associations with the district fund balance. Four are found to be positively associated, these include: foundation allowance, property taxable value, pupil-teacher ratio, and number of ELL students, which is one of the high-cost student indicators. The remaining six are enrollment, enrollment change, FRL, special education, salary, and business administrative expenditures and has a negative association with the district fund balance. Compared to districts located in rural areas, urban school districts have a lower fund balance, but for both school districts a higher fund balance could be achieved with more funding. On the other hand, giving money to school districts will not increase their fund balances. A plan must be put into place to spend the money effectively, taking into account teacher’s salary, class size control, and business administrative expenses. With all of these in mind school district managers will have a greater chance of maintaining their fund balance and fiscal status. Three cross-section regression analyses for fiscal years 2000, 2005, and 2010 with percent enrollment change in one and three years proved to be consistent with the pooled regression analysis. These cross-section analyses are useful in the short-term but will not estimate the fund balance accurately in five or ten years.

Overview Over the past few years, the number of Michigan public school districts that have a declining fund balance has been increasing. Many of them have deficits and are facing serious fiscal problems. These fiscal problems have captured the interest of Michigan educators, taxpayers, and lawmakers with regard to how the funding system works. The state’s education funding system was intended to improve the distribution of funding across school districts. However, the real per pupil revenue to fund schools has been declining since 2002, and this has forced school districts to respond with budget cuts. Michigan’s K-12 education funding, which relies on the state’s economic health, has been made even harder in the current recession. As a majority of states have reformed their mechanisms through which schools are funded, Michigan K-12 education has also gone through its own school finance reform. In 1994, Michigan adopted a new reform for school financing called Proposal A, the primary goal of which was to change the approach used in collecting and distributing revenues for education provided by the state. School funding was reformed by creating a new system in which the majority of revenues are raised by the state, and funding is distributed based on a per pupil foundation allowance formula, with foundation levels determined by the state annually. Most funds that support K-12 education are now controlled by the state, whereas local districts maintain control over capital funding, which is raised through local property taxes. Through the foundation allowance approach under Proposal A, the spending gap between 1 the highest-revenue and lowest-revenue school districts has steadily decreased since it was implemented (Arsen & Plank, 2003). However, the reform resulted in a shift from local to a centralized system of Michigan public school finance. Local districts are constrained with the revenue levels set by the state to survive with their budgets and adjust their spending priorities. Prior to Proposal A, Michigan’s public school funding relied heavily on local property taxes for education revenues. Michigan’s property tax burden was more than 33 percent above the national average before Proposal A was adopted (Michigan Department of Treasury, 2002). Aside from being concerned with education inequalities, Proposal A promised Michigan voters significant property tax relief. In order to compensate school districts for the loss of revenues, the sales tax and other taxes were raised to provide the state with the additional revenues needed. Since revenues for these taxes fluctuate with changes in the economy, school funding, which is now directly linked to the state’s economy, becomes less stable. When the state’s economy is facing a downturn, additional revenue to fund schools is no longer a possibility. Districts need to make adjustments in their budgets. However, not all of them are able to strengthen their financial condition. Some of them do not avoid falling into deficit, and the task is even more critical for those districts that already confront financial pressures. For example, Detroit Public Schools’ general fund has been in deficit every year since 2008. In 2010, the Michigan Department of Education (MDE) reported 43 school districts in financial deficit in the state. Seven of them are charter schools and 36 are public school districts (Appendix A). Even though this represents only five percent of the total of 848 education entities (551 local districts, 240 public school academies, and 57 intermediate school districts), it was a 138 percent increase from 2005, when there were only 18 school districts in financial deficit. According to the MDE, a district is considered a deficit district if it is not able to maintain a 2 positive fund balance at the end of the fiscal year. Deficit districts are then required to submit a deficit elimination plan (DEP) to MDE. The MDE has established a procedure that requires school districts to enter into a mandatory deficit reduction program when its audited financial report to the state reveals a deficit fund balance in the General Fund, or deficits in any other funds which surpass the surplus in the General Fund. Thus, not having a positive fund balance has placed many school districts in fiscal stress. If the districts fail to eliminate their deficits, their financial affairs will be intervened upon directly by the state under the Local Government and School District Fiscal Accountability Act (PA 4 of 2011). PA 4 supplants the Public Act 72 (PA 72) of 1990 under which State officials are authorized to intervene in the financial affairs of local governments that experience serious financial problems. It expands the authority of emergency managers over academic matters, contracts and agreements, and other district responsibilities. It is a very demanding task for a deficit district to prepare the required components of the elimination plan, especially if there is confusion about what caused its deficits. Knowing the underlying factors would give insight to district management if there are signs of more deficits in the near future. Being able to detect deficits ahead would enable districts to take preventive actions. Not only should deficit districts take preventive actions, other financially well-managed districts also need to do the same if they want to avoid deficits and not be in fiscal stress. Being in fiscal stress places a district in a vulnerable position. Thus, an understanding of the relationship between fiscal stress and its underlying factors should be of interest to all districts and state policy makers. 3 1.2 Statement of the Problem While the Michigan Department of Education (MDE) requires all school districts to maintain a positive fund balance, the number of districts that end their fiscal year in deficit keeps on increasing. Before these districts actually reported deficit in their fund balance, they must have been experiencing growing fiscal stress, but many were unable to rectify the condition. Local districts need adequate and reliable tools to anticipate instability in their fund balance. There is little research on the association of districts’ fund balances and their budgeting and other policy and community characteristics. Hence, it is essential to develop a model which can identify factors that associated with the variation of fund balance and thus will be helpful to school districts management to keep track with their fiscal status and prepare for any shortcomings. 1.3 Research Questions The focus of this study is to examine the indicators associated with fiscal stress in Michigan public school districts. This study is designed to answer the following research questions: 1. How has the financial profile of Michigan school districts changed over time? (a) How has the number of fiscally stressed and not fiscally stressed districts changed over time? (b) To what extent have individual districts moved in and out of fiscal stress? 2. What are the indicators associated with districts’ fund balances? (a) Are the indicators within or beyond local district control? (b) Is the model developed from the above indicators stable over time? 4 Financial profiles vary across districts. In the past ten years, many districts have maintained a good financial status, while some have fallen into deficit. With the current recession that has forced the state to make cuts in K-12 education funding, more school districts may fall into deficit. As captured in the first question, this study is interested to find out how the number of public school districts in financial difficulties has changed over time. The concern over fiscal stress should not be limited to districts having fund balance below this level. An examination of the changes in all district’s fund balance that affect fiscal stress will be useful to districts to know what they need to do to improve if their fund balance may put them in fiscal stress in the near future, or to continue to operate with little or no disruption. In order to do so, the factors that associated with the problem must be identified. The model developed in this study must not only be able to identify the factors that associated with fiscal stress accurately, it must be stable over time. This would help school districts to enhance their planning and allow more options at an early stage. Thus, the second question of this study explores the factors that account for school district’s fiscal stress by identifying the financial indicators that associated with fund balance, which is inversely related to fiscal stress, and the accuracy and stability of the model over time. 1.4 Significance of Study School district management needs to have some basic conceptual and empirical tools in order to identify factors associated with fiscal stress in their decision making. Identifying the factors could be helpful in preventing financial deficits by providing information on how the factors are related to the stress affect a district’s spending. Based on the information of the financial fiscal condition provided by the model developed in this study, it is hoped that an 5 accurate judgment of a district’s fiscal stress will benefit decision makers at the district and also state level to adjust the level of spending in a more timely and less disruptive manner for all districts and not only for deficit districts. 6 2 LITERATURE REVIEW The primary goals of Proposal A were to reduce property taxes and reduce the funding disparities across school districts. There is a substantial research literature on Proposal A and its impacts. This study limits its scope to the literature on the sources and distribution of revenue under Proposal A, identifying a number of issues that have arisen from the reform and, specifically the growing number of districts that confront financial deficits. This section also reviews research on fiscal stress and methods used to analyze it. Previous studies have proposed wide range measures of fiscal stress for local governments and school districts. However, none of them has identified a generally accepted standard model - that can fit the circumstances of school districts in other states or settings. 2.1 Proposal A Proposal A was approved by voter referendum and was implemented in 1994, and it continues to provide the basic framework for school finance in Michigan’s K-12 public schools. Proposal A introduced a new foundation-allowance approach to school funding that replaced the former district power equalization (DPE) plan. The new approach uses a mixture of state and local taxes to fund the K-12 educational system, but with more reliance on state taxes. Local school districts lost most control over the revenue available for their schools’ operation, and this made Michigan school finance system highly centralized at the state level. Under the reform, revenues come from a variety of sources. Table 2.1 summarizes the 7 changes in the revenue sources enacted when Proposal A was implemented. While sharply reducing local property taxes, the Proposal A system relies on revenues from sales and a variety of other taxes which are earmarked for the state’s School Aid Fund (SAF) to finance foundation allowances. New revenue sources that are directly deposited to the SAF now include the twopercentage point increase in the sales tax from 4% to 6%, the 50 cent per package increase in the cigarette tax rate, the 0.75 percent real estate transfer tax, the 14.4 percent of individual income tax revenues (increased to 23.0 percent in 1997), and the 6-mill state education tax levied on property. A percentage of state income tax collections is also earmarked to the SAF.

Michigan school finance under Proposal A; State control, local consequences. The Education Policy Center at Michigan State University. Proposal A established a classified property tax base comprised of homestead and nonhomestead property for the purpose of taxation. Homestead property is property that a taxpayer 8 declares as his or her primary residence. Except qualified agricultural property, all other property, such as business property, rental housing, or vacation homes, are considered nonhomestead property. As noted, the new finance system included a new statewide uniform property tax levy of 6 mills on both homestead and non-homestead property, with the revenue going directly to the SAF. Districts are required to levy 18 mills on non-homestead property and this is the main source of revenue that is generated locally. Most districts are not allowed to levy additional mills to finance general operating expenditures. Revenues from the tax on nonhomestead property remain at the local level. These local revenues, which comprise part of the districts’ foundation allowances, are offset dollar-for-dollar by corresponding decreases in state foundation aid. Average levies on both types of property were 34 mills before the reform, so the new provisions represent significant property tax relief for Michigan voters (Cullen & Loeb, 2004). The new funding system allows districts that were high-spending in 1994 designated “hold harmless” districts, to levy additional property taxes on homestead property (with local approval). With this local revenue, these districts are allowed to remain at their spending levels as before Proposal A. However, they are only allowed to increase their revenue every year by the amount of the annual increase in the statewide basic foundation grant, which applies to other districts as well. During the first three years after Proposal A was adopted, local voters could approve up to three additional mills to supplement the funding provided by the state. However, since 1997 local school districts are not allowed to seek any enhancement mills unless they join with other districts in their Intermediate School District (ISD). A majority of the electors in the ISD must approve the enhancement mills, and the revenues must be equally distributed across districts on a per-pupil basis. 9 Proposal A has reduced school funding inequities across districts, even though it has not eliminated them. The foundation allowance in the funding system reduces the fiscal disparities between school districts by establishing a minimum per pupil spending level for all school districts. In addition, state assistance is provided for districts lacking sufficient local revenues for the allowance. The Michigan Department of Treasury (2002) reported that in 1994, the ten lowest revenue school districts had weighted average per pupil revenues of $3,476, while the ten highest-revenue school districts had weighted average per pupil revenues of $9,726, nearly three times more than the ten lowest-revenue school districts. By 2003, the ten lowest revenue school districts had a weighted average per pupil foundation allowance of $6,700, while the ten highest revenue districts had a weighted average foundation allowance of $11,389, less than twice as much as the minimum foundation allowance (see also Arsen & Plank, 2003; Cullen & Loeb, 2004). The centralization of school funding under Proposal A has given the state the authority to determine operating funding levels for local school districts. Under such a highly centralized system, public schools as a whole should benefit from equities in the resources received. School funding becomes more equitable when the state constrains revenue growth in high-spending districts and provides more revenue to low-spending districts, and when districts do not rely on local property for school resources. 2.2 Challenges in Proposal A Even though some of the objectives of Proposal A have been achieved, the reform is not without its problems. Proposal A has not yielded gains for all school districts. It has affected different school districts in different ways. Due to the unique situation of every district, the way 10 the public school revenues are collected and distributed seems not to give the same value of educational equality or equity to all children across districts (Addonizio, 2003; Arsen & Plank, 2003; Zimmer & Jones, 2005; Izraeli & Murphy, 2007). The system has created issues for local districts that no longer have much control over their operating revenue and that are reliant on the state to determine school revenue levels. The next section discusses some of the issues, relating to the state’s economic crisis, declining enrollment, revenue-cost gap, and capital funding. 2.2.1 State Economic Decline Centralization directly linked Michigan education finance to the performance of the state economy. The school funding system created by Proposal A depends on a mixture of the state’s sales, income, and property taxes, which ultimately depend most on the health of the state economy. When Michigan was one of the richest states, Proposal A could distribute more revenues and improve equalization among school districts. However, after the state lost employment every year from 2000 to 2010 this was no longer a sure thing. During the initial years following Proposal A’s adoption, state operating revenue growth was strong, even though per-pupil revenue growth was moderate because of rising student enrollments. Unfortunately, Michigan’s sustained economic decline has diminished sales and income tax revenues that school funding relies upon most. After being funded at a higher perpupil foundation allowance since Proposal A was adopted (except in 1999), schools were stressed financially with a flat funding level of $6,700 in 2002 and 2003. The foundation allowance was cut by $74 in 2004 but went back to $6,700 in 2005. Then, House Bill 4887 was signed in 2005 to increase the minimum per-pupil foundation allowance to $6,875 for the 2006 school year. The increase was a relief to schools during this hard time, but it still did not solve the issue of unstable revenues that rely on the state’s economy and the financial problems facing 11 Michigan schools. Proposal A promised a minimum per pupil foundation allowance, more equity among local school districts, and lower property taxes. While taxpayers benefit from the property tax reduction, it puts limits on local school districts’ ability to generate additional revenues locally, specifically from the property tax. Indirectly, it has made the “local” revenues “state-controlled” revenues by largely eliminating local tax millage elections to raise operating revenues. To replace the reduced property taxes in school revenue sources, Proposal A increased sales tax revenues to fund school district operating costs. Since sales tax revenue is more cyclically sensitive than property tax revenue, this substitution put Michigan school funding in a less stable situation. Before Proposal A was adopted, earmarked taxes (both constitutional and statutory) used to be the total state-generated revenue going to the SAF, with a portion coming from the K-12 General Fund allocation (discretionary). Since the reform, the general fund plays a much smaller role in percentage terms because nothing in Proposal A requires general fund contributions to the SAF. The composition of the SAF has changed, and the revenues earmarked for the SAF have been insufficient to fund the state’s funding commitments to local schools. The difference, or deficit, has been covered by revenues from the state’s general fund budget. Since the single largest source for the fund comes from income tax revenues, the reduced income tax after the implementation of Proposal A, even only by 0.2 percent (down from 4.6% to 4.4%), affected the growth and the stability of Michigan education funding. In addition, the current recession has reduced the portion of income tax revenues. According to a report of the Citizens Research Council of Michigan (CRC, 2010), the 12 reduction in state dedicated funding in 2009 was partially offset by the availability of temporary funding provided through the 2009 federal “stimulus” legislation. Significant levels of nonrecurring federal monies were used in 2009 and 2010. Michigan receive additional federal resources, through another new “stimulus” program, to support the 2011 SAF budget. The report mentioned budget cutbacks, including a 2009/10 per-pupil reduction of $154, which also raises important questions regarding the revenue system Michigan uses to support its K-12 education. Even though the report emphasized that state and local operating revenue declines in 2009 and 2010 school years would not be fully reflected in the level of education services delivered, the cutbacks might spread cost-cutting in school districts, which in return, affect the service provided. The CRC Report (2010) also stated that the fiscal effects of Michigan’s heavy reliance on substantial amounts of one-time and temporary funding are that they produce revenue “cliffs” in some years and bring about an imbalance between current resources and current spending. As a result, Michigan taxpayers have been increasingly concerned about public schools, which are termed as being “under-funded”, and about the spending pressures that might have outpaced the resources available. The new funding structure under Proposal A had allowed Michigan to support current per-pupil expenditure levels that were above the national average, but it is evident that Michigan’s support for K-12 education is now declining. Since 2007, per pupil expenditure levels have fallen to the national average (The National Center for Education Statistics). Even though revenue stability is often desired, the stability and income elasticity of revenues that fund Michigan public schools can no longer promise equalization in Michigan school finance. Since the major source of revenue for school funds under Proposal A largely 13 depends on the state income and sales taxes, the reform makes school funding more sensitive to state economic conditions. The pace of per pupil revenue growth under Proposal A, which initially improved equalization among school districts, has slowed in recent years, and the revenues earmarked for the SAF have declined due to the economic downturn (Arsen & Ni, 2010). 2.2.2 Declining enrollment Under Proposal A, the amount of money that the state allocates to each school district depends on two main factors: the value of the district’s per-pupil foundation allowance, and the number of pupils enrolled in the district’s schools. The revenues available to the school district increase when the per-pupil foundation allowance increases, or when enrollment increases. Per pupil foundation allowances have increased in all districts since 1994, but some districts have enjoyed large increases while others have not. Meanwhile, enrollment has increased in some school districts, but fallen in others. Thus, the revenues allocated to school districts do not increase (or decrease) uniformly. Besides the per-pupil foundation allowance, this is due to the uneven changes in school enrollments across districts. Arsen and Plank (2003) note that while analyses of Proposal A have generally focused on changes in the value of foundation allowances, enrollment changes have had equally large effects on district revenues. Their findings displayed the interaction effects between changes in enrollments and changes in the per pupil foundation allowance and total revenues for selected districts. From 1994 to 2001, urban districts received mid-range per pupil funding increases since they fell in the middle range of Michigan districts. Yet, even during the initial stage, declining enrollment in central city districts produced declining total foundation revenues. Meanwhile, high-income suburbs enjoyed the fastest revenue growth, despite their small increases in per14 pupil funding, because they experienced the most rapid enrollment growth. Growing enrollment districts have benefited from Proposal A’s revenue distribution, while declining or static districts have fared less well. People movement from one place to another causes some districts gain enrollment, while some lose enrollment. Besides this, the Michigan school of choice policy also plays a role in influencing district enrollment. This policy is designed to allow local school districts to enroll non-resident students and count them in membership without having to obtain approval from the district of residence, and permits local school districts to enroll students who reside in other local school districts within the same intermediate school district (www.michigan.gov/mde). This practice removes resources of funding from the losing enrollment districts, though it helps raise revenues in preferred districts. A study by Arsen and Ni (2010) found that the differences in enrollment have generated inter-group variations in total revenue decline since 2002. They stated that between 2002 and 2008, the decline in real foundation revenue in Michigan’s central city districts was nearly four times the rate of decline in high-income suburbs. Revenues decrease much faster than costs, specifically in the current economic situation. Some costs are fixed in the short run, and districts or schools cannot simply reduce them as much or as fast as revenue declines. Even though declining enrollment eases fiscal pressures in one sense, because it diminishes the number of students by which the SAF has to be divided, schools with declining enrollment suffer from being under-funded due to less revenue received. Proposal A has no provision to help districts where enrollment is declining, and local voters have no option to ask for additional millage to offset revenue lost due to the enrollment drop. As a result, the funding system makes it harder for schools to provide an adequate 15 education for the students who remain enrolled. Addonizio (2003) concluded that urban districts with high costs and high proportions of children from low-income families appear to be substantially underfunded. This problem is intensified by declining student enrollments in these districts. If school enrollment and the number of high cost students are evenly distributed across the state, the foundation allowance received would have given even revenues to all school districts. 2.2.3 Revenue-cost gap After Proposal A was implemented, the state has increased (or decreased) every district’s per-pupil foundation grant (with minor exceptions) by the same dollar amount since 2001. Until today, three-fourths of all Michigan school districts now receive the same per pupil foundation allowance, while the remaining districts receive somewhat more. However, when looking across districts, not all districts incur the same per pupil costs in delivering education to different types of students. Every district is unique in its needs and problems, but the foundation allowance does not fully take into account the differential cost of educating students, for instance, students whose English is their second language (ELL), high school students compared to elementary school students, special education students, and students who come from a low social economic status family and who live in poverty. Such high-cost students are disproportionately found in urban schools, where the general consumer prices are also relatively high. Categorical grants offset only some but not all of the higher costs for special education, ELL, and low income students. Hence, the revenues districts receive should at least take into account the differences in the costs of the education provided to their students. The foundation grant under Proposal A is awarded at the district level, so the foundation amount is the same for each school within a district, no matter how different the costs of the 16 schools are. Thus, this creates a gap between district’s revenues and costs, specifically in districts with more high-cost students. Other than the same foundation amount that results in a gap between revenues and costs, the reduced amount of the categorical grants under Proposal A also makes the situation worse. Categorical grants are provided to schools by the state or federal government and may be spent only to pay for services needed by, for instance, low-income students and students with disabilities. The reform reduced the number of categorical grant programs in Michigan, which further reduced the total revenue received by districts. Since the costs to provide education for high-cost students who are mostly grouped in the categorical grant programs are higher in some parts of the state, the gap is even larger in some districts. The difference of revenues received and a faster increase of the costs to deliver education, particularly in recession, has forced many schools not to cater to high-cost students. Schools with high concentrations of them are left with daunting responsibilities. Addonizio (2003) mentioned that the adequacy of educational resources in high-cost and high-poverty districts has not been carefully examined since Proposal A was adopted. He was the first to examine the issue of adequacy and the costs related to it in an empirical way since Proposal A was adopted. He used data of school spending, achievement, and demographic from thirty Michigan urban school districts to determine the possible costs of an adequate education. Using an education cost formula, he displayed dramatic differences in costs when two relatively similar districts (Kalamazoo and Ypsilanti) were identified as the benchmark districts. He found educational insignificance of reaching equity benchmarks that do not reflect inter-district differences in educational costs, needs, and economic efficiency. Even though this paper does not discuss education equity and adequacy, it is evident that districts that have to pay higher costs for educational needs are being underfunded when compared to benchmark districts. One 17 could argue that being underfunded does not mean a district would be not efficient in delivering education, but Addonizio’s findings on MEAP test are clear. 2.2.4 Capital Funding While Proposal A has greatly centralized operational funding for Michigan’s K-12 schools, it leaves the responsibility of capital funding to local districts. Proposal A did not address funding for capital facilities. Expenditures for school capital continue to rely entirely on local property tax revenues. Typically, public school facilities in most states are funded with funds borrowed from the sale of general obligation bonds that are issued by local districts (subject to voter approval), where voters approve a certain increase in local property tax levies, for a specified period, to pay for the facilities. Under Proposal A, school facilities in Michigan remain a local responsibility, as it used to be before the reform. They are funded with distinct property tax levies from the mills assessed to fund school operations, and local districts have wide discretion to set these tax rates (millage). The tax rate required to generate funds that are needed by a district depends primarily on the per-pupil value of taxable property in the local district. Hence, property-wealthy districts could generate more revenue with relatively low tax rates, whereas property-poor districts must tax themselves at much higher rates to raise equivalent funds. Arsen and Davis (2005) found that the inequities in capital funding are greater than inequities in operational funding ever were, because of the difference between property-wealthy and property-poor districts. High-spending districts are able to fund their capital spending for better school resources to educate their students, while low-spending districts just remain in their old building structures, which then need more operating budgets for maintenance expenditures. 18 Old school facilities may require renovation for the purpose of increasing the number of students and for their safety, health, accessibility for the disabled, and a conducive learning environment. Due to the incapability to issue school bond loans in property-poor districts, schools in these districts would only be able to repair their existing facilities, which then pull the money out from their operating budgets. 2.3 Financial Consequences of Proposal A In general, Proposal A has brought positive changes into the Michigan’s school finance system. However, it has affected different school districts in different ways. Some districts are better off, while others are not. It is evident that the growth of both total and per-pupil real revenue for Michigan school districts has slowed since the passage of Proposal A, even though the total revenues available have increased. The state’s economic decline has indeed depressed the SAF revenues and will continue to do so in the current recession. Since 2002, annual increases in per-pupil foundation allowances have not kept pace with inflation, and this has forced school districts to find their best way to survive and take the consequences. One alternative is to improve efficiency. The challenge is especially critical for those districts that already confront financial difficulties as a result of Proposal A. When education revenues do not meet the rising operating costs that school districts face, they must go through budgetary changes and initiatives in managing a more equitable distribution of school funding to meet the challenges. This becomes more complex when revenue decisions are set centrally, but nearly all spending determinations remain at the local level under the current reform. Being unable to control the revenues received, what school districts can 19 attempt to do is control their spending. School districts are pressured to make changes in their budgets in order to restore their financial stability. The task is even harder for those districts that are already in deficit. All districts try to avoid having operating deficits in their General Fund at the end of the fiscal year because it is an indicator used by the Michigan Department of Education (MDE). Under current MDE procedures, as soon as a district discovers a deficit fund balance, it should notify MDE, and MDE will then notify the district of its obligation to submit a deficit elimination plan (DEP) to MDE. Until 2002, Proposal A led most school districts to improve their financial positions as measured by their fund balances. Yet for the school fiscal year that ended June 30, 2010, there were 43 districts (36 traditional school districts and 7 public school academies) with operating deficits (Michigan Department of Education, 2011). Since additional revenue is no longer a sure thing in the current recession, not only deficit districts but also other districts are under pressure to keep their fund balances in good shape. It is important to have a better understanding of the causes of the deficits so that school districts can sustain their fiscal health. Hence, districts should make adjustments to strengthen their financial condition and avoid falling into fiscal stress. 2.4 Fiscal Stress 2.4.1 Definition There are various ways to define fiscal stress1. Most definitions describe what the entity experiences as a result of financial problems (Trussel and Patrick, 2009). Fiscal stress, as defined 1 Fiscal stress and fiscal distress are used interchangeably in this literature, in reference to financial difficulties in State and local governments. 20 by Chapman (1998), occurs when there is a change in one set of several variables, but there are no offsetting changes in other variables. The variables include changes in revenue flows, changes in citizen tastes and preferences, changes in demographic characteristics of the jurisdiction, or changes in responsibilities of the jurisdiction. In any one of these variables, stress occurs because either changes in revenues received or expenditures demanded do not offset. Stress can occur through a slowly or quickly worsening condition and can create long-run and short-run pressures, or both at the same time. Chapman implied that the effects of stress must be examined in a longrun framework so that the complexity of both the stress and the responses to it can be understood. Bradbury (1982) defined fiscal stress by distinguishing between “budgetary fiscal distress” and “citizen fiscal distress”. She associated budgetary fiscal distress with short-term problems for local governments in balancing their budget. The problems are indicated by the locality’s surplus or deficit as a fraction of its budget. An alternative indicator of budgetary distress is the locality’s interest on general debt relative to general revenues, which would eventually show as high debt-related costs and generate an unbalanced budget. Her concept of citizen fiscal distress refers to longer-term difficulties for a local government in providing adequate local public services at a reasonable cost to its citizens. This fiscal distress is indicated by a high tax burden or high costs for basic services for local citizens. In charitable nonprofit organizations, Tuckman and Chang (1991) referred to fiscal stress as financial vulnerability and defined it as a constant decline in program spending. A nonprofit organization is financially vulnerable if it is likely to reduce its service offerings immediately when it experiences financial distress. The distress might be an economic downturn or loss of a major donor. Their model to examine the financial vulnerability of this type of organization 21 includes four indicators: equity ratio, revenue concentration, administrative cost ratio, and operating margins. In the government sector literature, there are also alternative definitions of fiscal distress. The U.S. Government Accountability Office (GAO) defines a fiscally distressed local government as one in which citizens and businesses bear substantially higher tax burdens in order to obtain levels of public services. Different communities tax their citizens and businesses at different levels to obtain similar public services. This happens because neither fiscal circumstances nor the needs for public services are uniform across communities. Thus, the distress makes it harder for poorer communities to provide adequate services on their own. There is no single definition of fiscal stress. Different researchers and government entities define it in different ways. Across the nation, states also have their own definitions and measures in classifying their fiscal stress. As for the state of Michigan, the Michigan Department of Treasury (MDT) has developed fiscal indicator scores for all local governments in the state (Michigan Department of Treasury, 2002). The state ranks local governments based on scores: 04 points represent a fiscally neutral position and requires no state action; 5-7 points indicate a "fiscal watch" condition and a cause for concern; and 8-10 points indicate fiscal stress and being placed on a watch list for the current and following years, and they receive consideration for state review. The ratings are based on key factors from nine categories: population growth, real taxable valuation growth, large real taxable value decrease, General Fund expenditure as a percent of taxable valuation, General Fund operating deficits, prior General Fund operating deficits, size of General Fund balance, fund deficits in current or previous years, and general long term debt as a percent of taxable value. If despite these preventive measures, local governments, including school districts, fall into a financial crisis, they are then governed by the 22 provisions of the Local Government Fiscal Responsibility Act, commonly known as Public Act 72 (PA 72) of 19902, which was supplanted by PA 4 of 2011. Under PA 4 of 2011, the governor may appoint a financial manager whose authorities would supersede those of the elected school board and superintendent. Even though there is no specific definition by the MDE for fiscally stressed school districts, it does require school districts to have a positive fund balance in order for them to avoid falling into deficits. Fund balance, the difference between assets and liabilities, is an important component to give an early warning if a district is falling into deficits. It measures a district’s fiscal condition by comparing the liabilities and assets of the district. A positive fund balance shows means a district has more assets than liabilities and a negative fund balance means there are more liabilities that assets. A gap between spending obligations and revenues over time, which has been an issue in Michigan public schools, would cause a structural deficit in school districts’ General Fund, even when the economy is recovering from recession. Being distinct from profit organizations, school districts only rely on revenues from local, state, and federal sources. Raising taxes might help school districts have more revenue sources, but Proposal A puts limits on property taxes that school districts can generate to fund current operations. Current operating expenditures, which include all instructional programs and supporting services, are deducted from the revenues to achieve fund balance. Hence, any changes in all these must be taken into account in defining the status of a district’s financial condition as being fiscally stressed or fiscally healthy. Considering the importance of fund balance in determining school district’s financial status, this study uses this variable to be examined and 2 The Local Government Fiscal Responsibility Act is the primary State statute under which State officials are authorized to intervene in units of local government that experience serious financial problems, or financial emergencies. 23 associated with fiscal stress. 2.4.2 Factors Associated with Fiscal Stress Any entity that faces or will face fiscal problems would be in a better position to monitor their financial status if they could identify the factors that contribute to fiscal stress. A small set of studies have identified ways to analyze the factors contributing to fiscal stress for public school districts (De Luca, 2006; Ammar et al., 2005; Manca et al., 1999) and local governments (Trussel & Patrick, 2009; Chapman, 2008; Coe, 2008). However, none of these studies has identified the same measures or benchmark in analyzing fiscal stress. De Luca (2006) investigated components of a school district that contribute to fiscal stress for 605 public school districts in Ohio. Her study used Ohio’s three classification of fiscal stress categories based on an examination of the overall revenue-expenditure ratio and a review of the degree of compliance with respect to the financial records submitted to the state: fiscal caution, fiscal watch, and fiscal emergency (Ohio Revised Code Section 3316.03 (A)). She then grouped districts according to district type based on a “Typology of Ohio School Districts” and district enrollment size, which was replicated from previous studies by Tamari (1978) and Brown (1993). The study included eleven ratio variables which were analyzed using a separate stepwise discriminant analysis to determine factors significantly associated with fiscal stress. The study found no single set of characteristics for all school districts that were associated with fiscal stress. Anticipating that no single indicator or set of indicators was likely to accurately associated with school districts at risk of future financial crises, Ammar et al. (2005) applied a financial condition indicator system (FCIS). Their framework used fuzzy rule-based systems 24 (FRBSs) to combine different units of the measures into an overall evaluation of financial condition. The FCIS developed in this study included four components: short-run financial condition – to measure a district’s ability to pay its bills and balance the budget without extraordinary measures; long-run financial condition – to measure a district’s capacity to finance adequate services over the long run without tax and debt burdens; economic condition – to reflect the impact of the local economy on the district’s capacity to raise taxes and on the expenditures needed to reach adequate student performance; and student performance – to measure whether students are meeting state standards. A total of fifty different measures of these components were analyzed to develop an early warning system that assesses a school district’s financial condition. Their study found that a strong short-run and a good long-run financial condition of some districts result from higher fund balances and liquidity ratios. They recommended that individual districts use the results of the FCIS for comparisons with districts of a similar size or need and resource capacity category. Manca et al. (1999) examined three school districts in California and Nevada regarding the circumstances they faced before and during a declaration of fiscal insolvency. They also examined key factors that contributed to regaining fiscal solvency, and statutory provisions in state law that helped resolve fiscal problems. Their qualitative study identified fourteen common factors which occurred in the districts, including declining fund balances over a period of three or more years; overspent revenues in the General Fund; overstated revenue income; the lack of budget tracking procedures and internal controls; understaffed Business Services; no long-range fiscal planning; breakdowns in communication; superintendents without a clear understanding of the financial position of the school districts; and out-of-date board policies and procedures related to fiscal management. They agreed that modifications in state funding should be made in 25 order to avoid fiscal insolvency and takeover by the state. Besides school districts, local governments may also experience fiscal stress. Trussel and Patrick (2009) presented a model incorporating financial risk factors associated with the likelihood of fiscal stress in local governments. They merged the 1998-2005 files of 2,633 local governments in Pennsylvania to create a cross-sectional time-series database which they examined using logistic regression methods. Their framework limited the risk factors of fiscal stress to four categories: revenue concentration – reliance on intergovernmental revenues and tax revenues; administrative expenditures – all general purpose expenditures made from the General Fund; debt usage – total liabilities and total liabilities to revenues ratio; and entity resources – total revenues and revenue growth. This study found that the risk factors of inter-governmental revenues, administrative cost ratio, debt level, and revenue growth are significantly related to the probability of distress with the predicted signs, while others are not statistically significant. Even though the model they developed can determine the likelihood that a local government will experience fiscal distress based on a few indicators, it cannot identify the underlying causes of the distress. Chapman (2008) mentioned that state and local governments will continue to face uncertainties to provide adequate services and infrastructure and will become increasingly constrained unless they have significant tools to stabilize their finances and maintain their fiscal sustainability in the long run. In his study on state and local fiscal sustainability, he discussed state and local governments’ current revenues and expenditures; three types of pressures that affect state and local sustainability - cyclical, structural, and intergovernmental; and three specific trends that are likely to affect the fiscal future of state and local governments – medicaid, pensions and retiree health benefits, and infrastructure; and finally he offered three 26 areas of potential solutions – revenue, expenditure, and administrative and management. He used measures from state and local revenues and expenditures in the years 1977, 1992, and 2004 for comparison purposes. The author concluded that the fiscal system needs to change in order to have fiscal sustainability. He warned that state and local fiscal sustainability will disappear if there are no changes in both revenues and expenditures in the fiscal system. Besides the three specific trends mentioned, this study ignored another crucial area, education, which very likely affects the fiscal future of state and local governments. In preventing local government fiscal stress, states not only need to detect the stress but also to take necessary actions to remediate it. A survey by Kloha et al. (2005) of state officials in New Hampshire, Florida, Maryland, North Carolina, Ohio, Pennsylvania, Kentucky, New Jersey, and New Mexico discussed how states detect distress in local governments and the best practices that some states use to prevent fiscal emergencies. The survey revealed the system used by the states to measure a local government’s fiscal condition. All the measures were extracted from the annual operating budget and financial reports. The results showed how states vary in providing assistance for local units due to their staff size and the state’s authority. Strong-authority states intervened by having local governments take corrective action and by increasing their revenues and/or decreasing costs; weak-authority states could only recommend changes; and no-authority states did not intervene in local financial affairs. The study found that states should have a system that detects fiscal distress, assists identified troubled localities, and strongly intervenes if a crisis situation arises in order to prevent fiscal stress in local governments. However, in establishing such a system, the author emphasized that states should take into account what they use to measure local governments’ fiscal condition. The literature reviewed here provides helpful tools in identifying early warnings of fiscal 27 problems in order to identify and prevent fiscal stress. Some apply similar methods while others are different. However, none of the studies suggests a standard model that could be used by all local governments and school districts. The models may or may not be applicable to other local governments or school districts. The use of one state classification of fiscal stress categories might fit only school districts in that state. Some states do not have any measures to classify their school districts if they should be in fiscal stress, and if they do, the measures should not be limited to the variables used in the studies reported in this literature. There is no single measure that fully captures the fiscal condition of a local government or school district. Even though different methods are applied to incorporate different measures in order to have not only one indicator or set of indicators to identify fiscal stress, many quantitative methods are particularly sensitive to measurement. Hence, small changes in variable measurement can lead to large changes in classification, thus classifying some districts in the wrong category. Other than the figures that we could extract from financial reports, a qualitative study such as Manca et al. (1999) is also important to give insight into identifying school districts which are not fiscally healthy. Identifying factors that associated with school districts’ fiscal stress needs further study and empirical work. A comparison of changes in revenue and expenditure is another way to measure how local governments or school districts maintain their fiscal health. The analysis by Chapman (2008) shows the percentage increase or decrease in revenue and expenditure in local governments. However, the comparisons of local revenues and expenditures across states at three specific years in a 27 year-period are not quite relevant due to the unique characteristics of how different states generate different levels of revenue and expenses, especially over such a long time. Even though past research highlights the importance of an analysis of fiscal status for 28 business entities, states, local governments, and school districts, few recommend appropriate solutions for them to get out of fiscal stress. Some studies recommend a state intervention policy in local districts to help them recover. However, without a proper understanding of the factors that associated with the stress, it is hard to identify the best strategies to adopt. Despite using various analyses to develop models to associate fiscal stress, none of the studies reviewed measure fund balance as a key factor to fiscal stress for school districts or local governments. School districts universally organize their accounting systems on a fund basis as defined by the national General Accounting Standards Board. A fund is established for accountability purposes to demonstrate that financial resources are being used only for permitted purposes. All school districts in Michigan have a General Fund and other smaller funds to account for specific activities. A fund balance is increased when fund revenues exceed fund expenditures for a fiscal period, and is decreased when fund expenditures exceed fund revenues. A positive fund balance represents a financial resource available to finance expenditures of the following fiscal period. A deficit fund balance can only be recovered by having revenues exceed expenditures in the following fiscal period. The reviewed studies did make use of fund balance in examining fiscal stress, but not as a factor being affected by other variables. The funding of Michigan public school districts depends on student enrollment, but no study in the literature used this factor as an input into a model of fiscal stress. De Luca (2006) grouped her sample by size, but each group was composed of a different number of districts. Michigan public school districts represent a wide range of sizes, and the difference results in a non-uniform enrollment and different educational needs and demands. There was no district grouping based on their fund balances per pupil in the studies discussed here. Determination of an appropriate fund balance is a critical factor in district 29 financial planning and budgeting processes. The MDE requires all districts to maintain a positive fund balance at the end of the fiscal year. A school district in Michigan is considered to have a deficit fund balance if its General Fund balance before reserves is negative, or other funds have negative fund balances that in total exceed the General Fund balance (http://michigan.gov/mde). In the fiscal year ending June 30, 2005, there were 18 school districts, plus four public school academies, in financial deficit. In 2009, there were 41 school districts with operating deficits, but eight districts successfully eliminated their deficits in the end of the year. In 2010, from the total of 33 districts that began the year with deficit, five districts were successful in reducing the deficit to the level indicated in their deficit elimination plan, three districts were able to reduce their deficit, but not to the extent contained in their deficit elimination plan, and 25 districts ended the year with a greater deficit. In addition, ten districts began the fiscal year with a positive fund balance, but incurred a deficit during the year. This made a total of 43 public school districts and public school academies that ended fiscal year 2010 in deficits. Local districts should not wait until their fund balance falls into deficit to know they are in fiscal stress. They should be able to detect the stress before that by examining the variations in their fund balance. Since Michigan school districts differ in their size and revenue received, fund balance as a share of total expenditures is used as a standardized measure in this study. Total expenditures is taken into account because it influences the amount of school district fund balance. School districts receive fund for only eleven months in a year but have to pay for a twelve-month expenses. Thus, they should have at least one twelfth or 8% of fund balance as a percentage of the total expenditures to pay for the twelfth month operations. For the purpose of this study, fiscal stress is defined as the inability of a Michigan public school district to maintain a sufficient 30 fund balance (8% of fund balance as a share of total expenditures) in the General Fund at the end of the fiscal year. 2.5 Conclusion Like a number of other states, Michigan continues to struggle with the issue of school funding in the current recession. The centralization of Michigan’s school finance system under Proposal A highlights some fundamental problems and makes it harder for school districts to improve efficiency with limited resources. The central role of student enrollment in state aid appears to have aggravated the financial burden of declining enrollment districts. The basis for distributing revenues to school districts does not reflect the actual cost of educating different students. Even though less enrollment reduces the number of students for whom the State Aid Fund has to be divided, it contributes less revenues to these districts and makes them suffer from being under-funded. Expenditures must be made, even with less revenue, to continue operating for the benefit of the children. Districts with these problems will continue to have financial difficulties. In the current economy, every school district has been trying to improve its efficiency by making full use of its revenues and by cutting costs to avoid a negative fund balance and being classified as a deficit district. The responses might include cost reduction in programs or services which in the end affect fund balance. It is important to know how school districts with different levels of fund balances make budgetary changes in response to student enrollment, and what they need to offset their limited revenue and expenditures to keep them in fiscal health. Being able to understand the variation in fund balance would place school districts in a better position to monitor their fiscal status and take preventive actions before it gets worse. It also offers valuable information to the state government on a district’s financial status. An early warning system 31 could allow decision makers to adjust the funding available to balance their budgets, rather than wait for deficit districts to have more deficits, and more districts to have deficits. Previous studies support the need to analyze the fiscal status of business entities, states, and local governments. Indeed, such forecasting models do exist for most of these areas. Even though substantial research has found a variety of characteristics that associated with fiscally stressed entities, there is no single model that is suitable for school districts in general, or for Michigan districts in particular. There is also reason to doubt the external validity of these studies to other entities in different places. While various measures have been proposed which could identify the causes of fiscal stress, fund balance could be a proxy of other risk factors associated with fiscal stress. The purpose of this study is to identify such factors. It examines the fiscal status of Michigan school districts based on the level of their fund balance. The association of fund balance and other factors that are related to districts’ characteristics and management strategies is investigated. It is hoped that this study will provide insight to Michigan public school administrators of how to understand the variation of their fund balance and factors associated with it, which then can be related to their fiscal status. It is also hoped that the findings and suggestions in this study will be a supplement to district management in understanding their fiscal status to avoid future problems. 32 3 METHODOLOGY The concern over districts’ fiscal stress must not be limited to having a positive fund balance at the end of fiscal year. The underlying factors that bring those districts to the stress point must be understood and addressed. It is hoped that a model to associate the likelihood of fiscal stress in Michigan school districts can be developed from the factors identified in this study. This section describes the research questions, the conceptual framework and hypotheses, data sources, variables, and analyses of the study. 3.1 Research Questions This study is designed to answer the following research questions: 1. How has the financial profile of Michigan school districts changed over time? (a) How has the number of fiscally stressed and not fiscally stressed districts changed over time? (b) To what extent have individual districts moved in and out of fiscal stress? 2. What are the indicators associated with districts’ fund balances? (a) Are the indicators within or beyond local district control? (b) Is the model developed from the above indicators stable over time? It is useful to envision two sets of factors that affect districts’ financial positions. Some of the factors are subject to district-level management, while others depend on district characteristics or circumstances that are largely outside the district’s control. For example, pupilteacher ratio, average teacher salary, and business and administration expenses are factors that 33 are subject to district-level management, whereas the enrollment, foundation allowance, number of high-cost students, number of economically disadvantaged students, and district property wealth are factors that are outside the district’s control. 3.2 Data Sources The Michigan Department of Education (MDE) requires all public school districts and charter schools each year to collect and submit data about students, personnel, and individual schools. Non-financial district-level data, which include enrollment, foundation allowance, property tax value, pupil-teacher ratio, teachers’ salary, and total business and administrative expenditure are accessed from the Michigan Department of Education (MDE). For number of students who receive free and reduced lunch and special education students, data are from the Michigan Center for Educational Performance and Information (CEPI), which assembles and maintains the data in the Financial Information Database (FID). Data for number of English Language Learners and status of community type are accessed from the National Center for Education Statistics (NCES). The Michigan School Business Officials (MSBO) provides data for fund balance. Data for 550 local public school districts for fiscal years 2000-01 to 2009-10 are collected and analyzed in this study. 3.3 Empirical Strategy This section describes the definition of dependent and independent variables, and the analyses that will be used in this study to find answers to the research questions. 3.3.1 Definition For the purpose of this study, fund balance as a share of total expenditures is used as an 34 indicator to explain fiscal stress in school districts. Fund balance is the difference between assets and liabilities of a fund. A positive fund balance means there are more assets than liabilities and a negative fund balance means there are more liabilities than assets. Total expenditures are taken into account in computing district fund balance in this study. This is due to the importance of this variable in determining the fund balance and it is also a standardized measure for all districts, which differ in their size and total revenue received. School districts are defined as being in deficit if they have negative fund balance as a share of total expenditures at the end of fiscal year. As for now, districts receive funds for only eleven months, but they must pay for the expenses of twelve-month operations. This generates a minimum of one-twelfth or 8% of fund balance as a share of total expenditures that a district should at least have to cover their expenses for the twelfth month. Thus, district’s status of being in fiscal stress is defined as the inability of a school district to maintain a sufficient fund balance of 8% as a share of total expenditures at the end of the fiscal year. Districts that have fund balance more than 8% of total expenditures are defined as not fiscally stressed. Districts that have negative fund balance (below zero percent of total expenditures) are classified as deficit districts and are also examined in this study. These definitions are used to answer research question one. Only district fund balance as a share of total expenditures is used as the dependent variable to answer research question two, without classifying them as in fiscal stress or deficit. 3.3.2 Dependent Variable This study examines district’s fund balance as a share of total expenditures as a dependent variable. Fund balance (FB*) is used to describe this variable. For each school district, the dependent variable is computed as: 35 Fund balance (FB*) = (district’s fund balance/General Fund expenditures) 100. 3.3.3 Independent Variables This study examines factors that might contribute to school district fiscal stress pertaining to issues of Michigan school funding as discussed in the literature review. The factors that contribute to a district’s financial condition are categorized as district characteristics - which are largely beyond local district control - and district management and those which are subject to local district control. Five main components make up the district characteristics: district size (enrollment), enrollment changes, concentration of high-cost students (percent of students who receive free or reduced lunch, percent of special education students, and percent of English language learners), district per pupil foundation allowance received by the state, community type (e.g. urban), and district property wealth (taxable value per pupil). The three components of district management are pupil-teacher ratio, average teacher salary, and business and administration expenses as a percentage of current operating expenditures (business and administration/current operating expenditures). The following is the description of each variable: District enrollment (enroll) – determined by the number of pupils legally enrolled and reported to the CEPI in the fall every year. Districts with high enrollment receives more revenues from the state because Michigan’s school funding system makes enrollment a key factor in determining districts revenues. It is directly related to revenues received by districts as well as their expenditures. It is unclear, a priori, whether this variable will have a positive or negative association with the dependent variable. Percent of enrollment change (%enroll ) – since enrollment has not changed evenly across districts, declining and many, it is important to know the net effect of if this variable on district’s 36 revenues and expenditures and hence their fund balances. One-year and three-year changes in enrollment are used in the analyses. A positive association is expected between this variable with the dependent variable. The following variables are related to issues of educating high-cost students in different regions of the state and different levels of district wealth. Percent of students who receive free or reduced lunch (%FRL) – the percent of students who are eligible for the National School Lunch program to receive free-or reduced-priced lunch. This eligibility is determined by students’ family income in relation to the federally established poverty level and is used as a proxy for students’ socioeconomic status. This variable is expected to have a negative association with the variation of fund balance. Percent of special education students (%SpecEd) – the percent of students with disabilities who are entitled to receive special education services through their local school district under the federal Individuals with Disabilities Education Act (IDEA). Since special education students cost more to districts, but not uniformly distributed across districts, it is important to know if there is an association of this variable with the variation of fund balance. It is expected to have a negative association with fund balance. Percent of English language learners (%ELL) – the percent of students whose first language is not English and who are in the process of learning English under the MDE Title III Program. Programs for this group of students cost more to districts, but their numbers are not even across districts. This variable is expected to associate negatively with the dependent variable. Per pupil foundation allowance (FA) – per pupil payment by the state for general school 37 operations created as part of the Proposal A. The state distributed larger funding increases in formerly low-revenue districts to narrow the per-pupil funding gap. Although the gap has been narrowed, there are still gaps between revenues received and the cost of educating students. It is essential to know if this variable has an influence on the fund balance. This variable is expected to have a positive association with fund balance. Community type (urban) – the location of school districts as categorized by the state according to the population density. Different regions have different regional cost of living. In general, urban areas tend to have higher cost of living compared to suburban and rural areas. Thus, it is expected to see a negative association between fund balance and districts that are located in urban. Property taxable value per pupil (SEV) – the value used to calculate the property taxes for a property since Proposal A was adopted. SEV reflects property wealth and the fiscal capacity of a district. This variable is expected to have a positive association with the dependent variable. Pupil-teacher ratio (PTR) –defined as a district’s Fall Pupil Count, excluding adult education participants, divided by the total number of K-12 teachers. This variable reflects how districts try to reduce their expenditures if the class size is big. It is expected to have a positive association between this variable and fund balance. Average teacher salary (salary) – full-time and prorated portions of regular teachers’ salaries for teaching services provided to pupils, divided by enrollment. This variable is used to see how districts’ spending on teacher salaries is associated with their fund balance. It is expected to show a negative association between them. 38 Business and administration expenses as a percentage of current operating expenditures (BusAdm/COE) – the percentage of the total cost of general administration, school administration, business services, central services, and other support services from the total of current operating expenditures. This variable shows how districts manage their expenditures and is expected to inversely influence the fund balance. Table 3.1 summarizes the independent variables with the expected sign of how they would affect the dependent variable: Table 3.1 Fund Balance Indicators Indicator 1. District enrollment 2.

Financial data for a ten-year period from fiscal year 2001 to 20103 are evaluated in order to determine how the number and composition of school districts in financial difficulty has changed over time. Districts are grouped into two groups based on their 3 Academic years refer to calendar years, e.g. academic year 2000-2001 refers to calendar year 2001. 39 fiscal status – fiscally stressed if their fund balance is below 8% and not fiscally stressed if their fund balance is above 8%. A dummy variable is created for school district’s location. District locations are defined as urban or not according to the definitions of the National Center for Education Statistics (NCES). The definitions are used as guidelines for the urban (Appendix B): 11 - City, Large; 12 - City, Midsize; 13 - City, Small; 21 - Suburb, Large; 22 - Suburb, Midsize; 23 - Suburb, Small; 31 - Town, Fringe; 32 - Town, Distant; 33 - Town, Remote; 41 - Rural, Fringe; 42 - Rural, Distant; 43 - Rural, Remote. All districts with locale codes that start with 1 or 2 are defined as urban and districts with locale codes that start with 3 or 4 are defined as not urban Before analyses are conducted, the data are tested for the assumptions of collinearity, normality, and homoscedasticity. To address research question number two, data for fiscal years from 2001 to 2010 are pooled and analyzed using multiple linear regression method. The dependent variable is regressed against the eleven predictors. For each school district, the estimated regression equation is: FB * = + + + + + + + + + + + + (1) Three one-year models are also examined at three time periods, fiscal years 2000, 2005, and 2010 with multiple linear regression analysis. These three points of time seem reasonable, 40 especially in light of the significant increase in the number of deficit school districts from 2000 to 2005 and 2010. The regression equations analyzed for the three years are the same as Equation (1) but at three different snapshots of time. Because one year enrollment change could be relatively small, three one-year models are also examined for the three fiscal years with the predictor of percent of change in enrollment is calculated three years back. In order to see how accurate and stable the model, the next step is to check the accuracy of the estimated fund balance compared with the actual fund balance. The estimated coefficient and intercept values for one year are applied to the actual values of independent variables in another year. For this purpose, the coefficients and intercept from fiscal year 2000 estimated model is applied to the fiscal year 2010 equation. The results of this estimated dependent variable of 2010 are then compared with the actual dependent variable of 2010 data. The purpose is to see how accurate the model is after ten years. The estimated regression equation is: ̂ = + + + + + + + + + + + + (2) 41 The difference between the estimated and the actual 2010 amount of stress is calculated for each district. The actual estimates of 2010 are also compared with the estimated coefficients of 2005 in order to see how accurate the estimation is if it is after five years. Then, the same process is done for the estimated data of fiscal year 2005 by using the coefficients and intercept from fiscal year 2000. 42 4 RESULTS This chapter presents results of the statistical analyses to answer all the research questions. It is divided into two main sections. The first section addresses the first research question with descriptive analyses for all variables in this study for all districts over ten years. Districts are grouped based on their fund balance and changes in their status of being in fiscal stress. The second section of this chapter presents the pooled regression analyses results to answer the second research question. Cross-section regression analyses are also examined and compared at three snapshots of time. Then, actual and estimated data values are compared for differences to check for model stability. Charter and private schools are excluded from the original data. 4.1 Descriptive Analysis This section provides answers to the research question 1: How has the financial profile of school districts changed over time? a. How has the number of fiscally stressed and not fiscally stressed districts changed over time? b. To what extent have individual districts moved in and out of fiscal stress? Tables 4.1and 4.2 provide descriptive information for all variables. The fund balance variable is measured as a share of the General Fund expenditures. Since school districts differ in their size and total revenue they receive, fund balance as a percentage of total expenditures represents a standardized measure. The statistics show a large range between the minimum and 43 the maximum fund balance throughout the ten years, ranging from a low of -48.65% to a high of 313.86%, with mean at 18.26%. Enrollment has a big gap from a low of 2 students to a high of 164,506 students. Of the three indicators of high-cost students, percent of students who receive free and reduced lunch has the largest variance from a minimum of 0 to 100% and a mean of 35.59.

From the total of 550 school districts examined, 170 districts (30.9%) are located in urban and 380 districts (69.1%) are not located in urban.

As the number of Michigan public school districts with negative fund balance has been increasing for the past few years, it is good to know how their fund balance as a percentage of total expenditures vary in the last ten years. Table 4.3 displays the comparisons of fund balance (as a percentage of total expenditures) in all districts from fiscal year 2001 to 2010. Table 4.3 District Fund Balance as a Percentage of Total Expenditures, 2001-2010 N 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 550 550 550 550 550 548 549 549 550 550 Minimum Maximum Mean SD -8.40 -6.00 -7.87 -12.73 -15.89 -31.16 -43.73 -48.65 -39.57 -38.24 313.86 218.15 238.34 252.06 223.95 187.35 218.30 259.68 243.36 248.54 20.10 21.10 20.56 19.49 18.01 16.48 16.96 17.55 16.58 15.77 26.74 24.47 24.14 23.00 21.61 21.50 23.55 25.81 25.31 25.96 Over the ten-year span, fund balance as a percentage of General Fund total expenditures ranged from a low of -6%(2002) to a high of 313.86% (2001). The mean range is between 15.77 (2010) and 21.10 (2002). The mean of fund balance has generally declined since fiscal year 2003, the year that marked the beginning of a sustained slowdown in state foundation allowance growth. Table 4.4 displays the distribution of school districts in five groups defined by their fund balance. The first group in the table represents school districts with negative fund balance. The 4 Fund balance as a percentage of total expenditures 45 number of deficit districts declined between 2001 and 2003 and increased thereafter. This group experienced the largest increase in the number of districts (26 districts) in the ten years. Whereas, districts with fund balances greater than 24% of spending had the largest decrease. This group had declined by 55 districts in those years. Districts with fund balances of 0 – 8% of total expenditures had the second largest increase. This group had an increase of 19 districts in ten years. In general, more school districts are having a declining fund balance. Looking at the highest group (> 24%), not all 30 districts that had a decline in their fund balance in 2004 went down to the next lower group (16 – 24%). This group only had an increase of 22 districts. Even though it is not known which districts made the new number in this group, it shows that some of the districts from the highest group had much lower fund balance and went further down to the other lower groups. The same movement can also be seen in fiscal years 2006, 2009, and 2010.

The cutoff point is set at 8% because this is the least amount of fund balance school districts need to have in order to avoid borrowing to cover current operations. The state disburses school aid to local districts in eleven monthly payments. If they are to avoid short term borrowing, districts must have fund balance of at least one twelfth or 8% of total operating expenditures to pay for the twelfth month expenses. Based on this definition, school districts are grouped in either being in fiscal stress or not in fiscal stress as summarized in Figure 4.1 and Table 4.5. Figure 4.1 Number of Fiscally Stressed and Not Fiscally-Stressed Districts, 2001-2010 For interpretation of the references to color in this and all other figures, the reader is referred to the electronic version of this dissertation. 47 Table 4.5 Number of School Districts in Fiscal Stress, 2001-2010 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 Stressed Not Stressed Frequency % % Change Frequency % % Change 130 23.6 420 76.4 110 20.0 -15.25 440 80.0 4.71 110 20.0 0.00 440 80.0 0.00 111 20.2 1.00 430 79.8 -0.25 134 24.4 20.79 416 75.6 -5.26 158 28.7 17.62 390 70.9 -6.22 152 27.6 -3.83 397 72.7 2.54 146 26.5 -3.99 403 73.3 0.83 161 29.3 10.57 389 70.7 -3.55 175 31.8 8.53 375 68.2 -3.54 Total N 550 550 550 550 550 548 549 549 550 550 The number of fiscally-stressed districts increased between 2004 and 2010. The biggest increase occurred in fiscal year 2005. As the number fiscally stressed districts increased, the number of districts not in fiscal stress decreased. Even though the magnitude of the increasing number of fiscally-stressed districts remains modest, the overall trend is worrisome for state and local education officials. A further analysis of fiscally stressed districts is displayed in table 4.6. The table also shows a comparison with districts that have a negative fund balance or deficit. The purpose is to identify the number of districts that have had below zero fund balance and those that have been slightly above zero fund balance. This would indicate district’s strategies in managing their finances when they do not have too much fund left but still manage to avoid deficits. 48 Table 4.6 Districts in Fiscal Stress* and Deficit**, by Number of Years Number of years Number of districts Fiscal stress Deficit 0 261 499 1 53 10 2 37 16 3 26 4 4 37 6 5 23 6 6 26 3 7 19 2 8 17 4 9 15 0 10 36 0 * where fiscal stress = fund balance/total expenditures < 0.08 ** where deficit = fund balance/total expenditures < 0 From the total of 550 school districts, 261 districts or less than half never have fiscal stress since 2001. One hundred and thirty-six districts or 25% of total districts have been in fiscal stress for 5 years and more. This group of districts should be on the state watch list. 36 districts are in a severe situation with ten consecutive years of being in fiscal stress. They have not been in good fiscal health since 2001. In contrast, only 15 districts have had negative fund balance for five years and more from fiscal year 2001 to 2010 and 499 districts never have negative fund balance. It is good to know that more than 90% of total districts never experienced deficits in the ten years. There are 238 districts with fund balance below 8% which nevertheless still manage to keep their fund balances from turning negative. For at least once in those ten years, there are 289 districts that have had fund balance below 8%, while there are only 51 districts have had fund balance below 0%. Out of this total, for five years and more, 136 districts have been below 8% of fund balance, whereas only 15 districts have been below 0% of fund balance. No district maintained a negative fund balance for all ten years. 49 Despite the fact that the MDE requires all districts with negative fund balance to enter into a mandatory deficit reduction program, some districts are still not improving even after few years having fiscal stress. Table 4.7 lists all of the districts that have been in fiscal stress for ten years. Clearly, some districts are chronically in precarious financial condition, even for years.

In addition, districts that have had deficits for five years and more should be on the state watch list. More attention should be focused on those districts that have been in deficit for eight years since 2001. They could get into more deficits in the coming years if some precautions are not taken. Table 4.8 lists all the districts that have had deficits for five years and more. 50 Table 4.8 Districts in Deficits from 2001 to 2010, by Number of Years Number of Years 5 6 7 8 Districts Hancock Public School Clintondale Community Schools Muskegon Heights School District Vanderbilt Area Schools Willow Run Community Schools Inkster City School District Ironwood Area Schools Dollar Bay-Tamarack City Area Schools Garden City School District Beecher Community School District Ecorse Public School District New Haven Community Schools Madison Public Schools Ewen-Trout Creek Consolidated Schools Redford Union School District I turn now to examine school districts movement of in and out of fiscal stress and deficits. The movements reported are the number of change in district status, which is divided into two groups: (1) fiscally stressed districts - report movements from fiscally stressed to not fiscally stressed and from not fiscally stressed to fiscally stressed and (2) deficit districts – report movements from positive to negative balance and from negative to positive balance. Table 4.9 displays the number of districts with the number of change in their status. Table 4.9 Number of District Movement of Fiscal Stress* and Deficit**, 2001-2010 Not fiscally stressed Fiscally stressed Deficit not deficit not fiscally stressed fiscally stressed Number Number Number Number Number Number of change of district of change of district of change of district 1 147 1 174 1 25 2 24 2 33 2 1 3 4 3 4 * where fiscal stress = fund balance/total expenditures < 0.08 ** where deficit = fund balance/total expenditures < 0 51 Not deficit Number of change 1 2 deficit Number of district 33 10 The column for fiscal stress shows 147 districts have one movement in their status from fiscally stressed to not fiscally stressed, 24 districts with 2 movements and 4 districts with 3 movements in the same direction. What these districts have done to move out from fiscal stress should be followed by other districts that are in the same situation. Whereas, there are 174 districts that have moved once from not fiscally stressed to fiscally stressed, 33 districts have moved twice and 4 districts have moved three times. These districts, especially districts that have moved three times, should be watched closely so they will not have fiscal stress again. Four districts have the most number of movements (3) of in and out of fiscal stress. There is no district that has experienced moving in and out of fiscal stress more than three times over the ten years. However, it should be reminded that 36 districts, as presented in Table 4.7, are in fiscal stress for ten consecutive years and have not moved out from the stress. Districts that have moved three times from not stress to stress in the ten years and should be on the watch list not to fall into stress again are Ashley Community Schools, Montabella Community School District, Walkerville Public Schools, and Posen Cons School District. Whereas, districts that recovered three times from stress are Fennville Public Schools, Jonesville Community Schools, Baldwin Community Schools, and Waterford School District. Even though these districts are able to move out three times from fiscal stress, it should be reminded that they have also been in fiscal stress for at least three times too. For deficit districts, 33 districts have moved once from not deficit to deficit and ten districts move twice in the same direction. These 43 districts should be monitored closely too and they must do their best to not enter deficits again. Meanwhile, 25 districts have recovered once and one district has recovered twice from deficit when they moved out from negative to positive fund balance. Even though these 26 districts were in deficit, they should be models to other 52 districts as how they got out of it. There is no district that has more than two changes in their status in both movements, but there are 15 districts (Table 4.8) that have been in deficit for five years and more. 4.2 Regression Analysis A regression analysis was conducted to address the research question 2: What are the indicators associated with districts’ fund balances? (a) Are the indicators within or beyond local district control? (b) Is the model developed from the above indicators stable over time? The association between the predictor variables and the dependent variable is examined to give an insight whether it is generated by district management or factors that are beyond local district control. The dependent variable is fund balance as a percentage of total expenditures (FB*), which is inversely related to fiscal stress. The predictor variables include eight variables which are (1) beyond local district control: enrollment (in thousands), percent of change in enrollment, percent of students who receive free and reduced lunch (FRL), percent of special education students, percent of English Language Learners (ELL), foundation allowance (in thousands), urban, and property taxable value per pupil (in thousands); and (2) within local district control: pupil-teacher ratio, average salary (in thousands), and business administrative expenditures as a percentage of current operating expenditures (COE). The first test on normality shows the data are not normally distributed and the presence of outliers. Consequently, all variables except urban, are transformed into log. A dummy variable is used to identify urban. All districts in city and suburban are defined as urban and all districts in city and rural are defined as not urban. The assumptions of normality, collinearity, and homoscedasticity are first tested 53 before regression analysis is conducted. There are missing financial data for District 23490 Oneida Township School District in fiscal year 2007 and 2008. Since data for ELL only started in 2002, this variable does not have any data for fiscal year 2001 for all districts. A mean imputation is applied to replace them with the mean of the other nine-year data5. 4.2.1 Test of Assumptions First, the assumption of multicollinearity is tested. The correlations among pairs of the variables do not show high correlations. The highest correlation is 0.65, which is between urban and enrollment. Futher, the variance inflation factor (VIF) is used to detect multicollinearity in the data. The VIF results for multicollinearity test are displayed in Appendix C. The VIF represents the multiplicative increase in the variance (squared standard error) of the estimator due to being correlated with other predictors (Agresti & Finlay, 2009). The threshold of VIF is three and any VIF values of more than this value is considered as evidence of serious multicollinearity. Since none of the independent variables has a VIF greater than three, it indicates that there are no clear multicollinearity problems. The next assumption tested is a test of normality. A histogram of standardized residuals shows a roughly normal curve (Appendix C). The histogram has a slightly longer tail on the left which indicates a not normal distribution. Yet, the normal probability plot shows the values fall nearly on the straight line. Thus, the normality assumption appears to be satisfied. The next assumption to test is homoscedasticity. Based on the result of scatter plots, there is no clear heteroskedasticity presents. This shows that the variance of residual error is constant 5 The results were insensitive to alternative specifications of the imputation. 54 for all values. According to the results, it is generally decided that all assumptions are met and the regression results could be examined and interpreted as they are. 4.2.2 Pooled Regression Analysis The data from fiscal year 2001 to 2010 are pooled across districts to run an ordinary least squares (OLS) regression model to investigate which predictor variables are associated with the dependent variable. The regression results report two models: (1) without year dummies and (2) with dummies for years. Both models provide statistically significant estimation of fund balance: (1) F = 344.963, p < 0.01 with = .410 and (2) F = 195.310, p < .01 with = .418. Table 4.10 displays the results. The first result with no year dummies show a positive association between fund balance and the predictors of percent of enrollment change, percent of ELL, foundation allowance, and property taxable value/pupil. However, percent of enrollment change and ELL do not have a significant association with fund balance. As expected, an increase in percent of enrollment change, foundation allowance, and property taxable value increase district fund balance. ELL shows an opposite association with fund balance from what is expected. There is a negative and significant association of fund balance with the predictors of enrollment, percent of FRL, special education, urban, pupil teacher ratio, salary, and business administrative expenditures/COE. Two of the variables that describe high-cost students - percent of FRL and special education - significantly decrease district fund balance. School districts located in urban have less fund balance compared with those in rural areas. All of three variables that related to district management - pupil teacher ratio, salary, and business administrative expenditures – reduce district fund balance if there is an increase in these numbers. As indicated 55 by pupil-teacher ratio, the result shows that districts have higher fund balance if they have bigger class size.

The first five fiscal years, 2001 – 2005, are significantly associated with fund balance. This indicates that compared to fiscal year 2010, fund balance in fiscal years from 2001 to 2005 has a significant increase. Though not significant, the next five fiscal years also have a positive association with district fund balance compared to fiscal year 2010, but at a declining rate. After the year dummies are added, percent of enrollment change and pupil teacher ratio show the opposite association with fund balance. Enrollment change is now negatively associated with fund balance, while pupil teacher ratio is positively associated although both of them are not significant. Other predictors that have a positive association with fund balance are percent of ELL, foundation allowance, and property taxable value. Not like foundation allowance and property taxable value, ELL was not expected to have a positive association with fund balance. Besides enrollment change, there is also a negative association between district fund balance with enrollment, percent of FRL, special education, urban, salary, and business administrative expenditures. Of all the variables that are beyond district control, only percent of ELL, foundation allowance, and property taxable value help increase district fund balance. Fund balance is negatively associated with other district characteristics that are beyond their control. District management on the variables that are within their control, which are pupil-teacher ratio, average salary, and business administrative expenditures, help increase fund balance. 57 4.2.3 Cross-Section Regression Analysis Three one-year models are also examined at three time periods, fiscal years 2000, 2005, and 2010. These three points of time seem reasonable, especially in light of the significant increase in the number of deficit school districts from 2000 to 2005 and 2010. Because one year enrollment change could be relatively small, the three models are also examined for the same fiscal years with percent enrollment change calculated over three years. The regression equation tested for each of the three years is: = + + + + + + + + + + + + Table 4.11 displays the results of the regression analysis for fiscal years 2000, 2005, and 2010 using percent enrollment change in three years. For comparison, Table 4.12 presents the results of regression analysis of the same three fiscal years, but with a one-year change in enrollment. All models in both tables provide statistically significant estimation of fund balance at p<0.05. The variation in fund balance explained by the predictors decreases slightly. They are 38.7% in 2000, 38.5% in 2005, and 29.8% in 2010 with percent enrollment change in three years and 38.6% in 2000, 38.6% in 2005, and 31.2% in 2010 with percent enrollment change in one year. 58 Compared with pooled regression analysis, the results in Table 4.11 show consistency. Enrollment, FRL, special education, ELL, foundation allowance, urban, property taxable value, and business administrative expenditures/COE show the same direction of association with district fund balance. However, only enrollment, percent of special education, and business administrative expenditures/COE are consistent in their significance and direction in associating with fund balance.

However, percent enrollment change is not significantly associated with fund balance in the three years. It has a negative association with fund balance only in fiscal year 2005. Higher enrollment change is associated with higher fund balance in fiscal years 2000 and 2010, but not in 2005. Except for ELL students, the other two indicators for high-cost students - percent of FRL and special education – result in a significant lower fund balance if these number of students increase. Percent of ELL students does not have a significant association with fund balance even though they are positively associated. This shows this group of students seems less relevant related to fund balance. Foundation allowance and property taxable value are also becoming not significant recently even though they seem to have a positive influence on district fund balance. Urban school districts appear to have lower fund balance than rural school district in all three years, though being significant only in 2005. How school districts manage their spending on pupil-teacher ratio, salary, and business administrative expenditures are found inconsistent in influencing the fund balance they have. In general, it appears that district management indicators of salary and business administration are only significant when they have a negative association with fund balance. It shows that the more they save on salary and business administration, the higher fund they have in the end of fiscal year. However, district control over class size shows both significant positive and negative association with fund balance in 2000 and 2010. Bigger class size, as indicated by pupil teacher ratio, helps district increase their fund balance in 2000 but not in 2010. 60 Table 4.12 Regression Analysis of District Fund Balances, 2000, 2005, 2010 (percent enrollment change in one year) Constant Enrollment % enrollment change % free and reduced lunch % special education % of English Language Learners Foundation allowance/pupil Urban Property taxable value/pupil Pupil-teacher ratio Average salary Business admin./COE 2000 B (SE) 1.666** (.304) -.093* (.038) .114 (.084) -.004 (.016) -.260** (.033) 2005 B (SE) 1.668** (.289) -.061 (.037) -.063 (.071) -.071** (.024) -.286** (.037) .024 (.022) .483* (.228) -.061** (.019) .022 (.035) -.013 (.125) .087 (.159) -.175* (.088) .386 1.241** (.224) -.034 (.021) .086* (.041) .791** (.191) -1.004** (.186) -.498** (.075) .386 2010 B (SE) 2.830** (.289) -.095** (.034) .180** (.053) -.121** (.032) -.107** (.037) .017 (.019) .081 (.207) -.030 (.018) .060* (.030) -.269* (.106) -.282* (.124) -.354** (.018) .312 p < .01** p < .05* Looking at both Table 4.11 and Table 4.12, the magnitude of all coefficients does not show a consistent increase or decrease, but more predictors are becoming significant lately in 2010. Compared with results that use three-year change in enrollment, a one-year change in enrollment becomes significant in 2010 and positively associated with district fund balance. This indicates a higher fund balance with higher enrollment change. On the other hand, enrollment is still negatively associated with fund balance in all three years and only significant in 2010. 61 Though not significant, percent of ELL is consistently showing a positive association with fund balance if compared with results with three-year enrollment change and pooled regression. Percent of FRL, special education, urban, and foundation allowance are consistent in the direction and significance of association with fund balance. Property taxable value is becoming significant recently. District control on pupil-teacher ratio does not show a consistent result. It has a negative association with fund balance in 2005 and 2010, but only significant in 2010, and a positive and significant association with fund balance in 2000. District management in reducing salary helps increase fund balance in 2000 and 2010 but not in 2005. District should pay more attention in reducing business administrative expenditures since this variable shows a consistent and significant influence on fund balance. 4.3 Model Stability Finally, this section examines the stability of the models developed from the cross- section regression analysis in the three years to estimate fund balance. The actual fund balance for 2010 is compared with the fund balance estimated from the regression equation for the same year but functioned with the coefficients from 2005 and 2000. Then, the actual fund balance for 2005 is compared with the fund balance estimated from the regression equation for the same year but functioned with the coefficients from 2000. This is done with regression model that uses a one-year enrollment change. Then, paired sample t-test is performed to compare the differences between the two variables in each pair. Table 4.13 displays the significance of the difference between the actual and estimated values. The mean difference is the actual fund balance subtracts the estimated fund balance. 62 Table 4.13 Paired Samples Test Model Year Used Estimated 2000 2000 2005 2005 2010 2010 Paired Differences Mean SD SE mean -.0274 .1932 .2036 .1576 .1529 .1430 .0067 .0065 .0061 t 95% Confidence Interval of the Difference Lower Upper -.0406 -.0142 -4.071 .1804 .2060 29.071 .1917 .2156 33.380 Df Sig. 549 549 549 .000 .000 .000 From the table, it appears that when coefficients in model 2000 is used in 2005, the estimated fund balance tends to be higher than the actual fund balance, which is described by negative mean value. The actual fund balance tends to be higher than the estimated fund balance when coefficients in models 2000 and 2005 are used in 2010. The results show there are significant differences in actual and estimated values of fund balance, which indicate that the models at the specified years are not stable in estimating fund balance five or ten years later. The confidence interval suggests that we can be 95% confident that the actual fund balances are within the estimated limits. Despite the significant differences between the actual and estimated fund balances, these models provide statistically significant estimation of fund balance in each year, as discussed in the cross-section regression analysis. It can be concluded that the models are significant to estimate fund balance in the respective years, but not to estimate fund balance five or ten years later. 4.4 Conclusion In conclusion, the analysis of school districts financial profile reveals that in general, the mean of fund balance (as a percentage of total expenditures) has been declining. From fiscal year 63 2001 to 2010 few districts moved out of fiscal stress and deficits, while there are some districts that entered fiscal stress and deficits. There are a number of districts that should be on the state severe list and watch list based on the level of their fund balance. The investigation of factors associated with fund balance through pooled regression analysis show that enrollment, percent of students who receive free and reduced lunch, percent of special education students, foundation allowance, urban, property taxable value, salary, and business administrative expenditures/COE are significantly associated with fund balance, while other variables are not significantly associated with fund balance. Although not significant, district fund balance unexpectedly increases if there is an increase in the number of ELL students, which is one of the high-cost student indicators. Increase in foundation allowance, property taxable value, and pupil teacher ratio also helps increase district fund balance. Enrollment, enrollment change, FRL, special education, salary, and business administrative expenditures have a negative association with district fund balance. Fund balance of a school district which is located in urban is lower than those located in rural areas. In general, district fund balance can be improved by controlling their spending in the areas that are within their control. Even though lower expenses in district characteristics help increase their fund balance, these variables are beyond their control. Compared to fiscal year 2010, fund balance in fiscal years from 2001 to 2005 has a significant increase. Three crosssection regression analyses for fiscal years 2000, 2005, and 2010 show consistent results with the pooled regression analysis. The three-year models are significant to estimate fund balance in the respective years, but not to estimate fund balance five or ten years later. 64 5 DISCUSSION The final chapter of this study presents the researcher’s interpretations of the findings. The following sections in this chapter summarize and restate the entire study, the research questions, and the results. Interpretations, implications, and recommendations are offered at the conclusion of this chapter. 5.1 Summary of the Study Financial difficulties have put many school districts in fiscal stress. Therefore, these districts must learn ways to improve fiscal health in order to achieve a positive fund balance. Imbalanced budgets put every school district at risk of a negative balance, so in an attempt to counteract this growing trend, the Michigan Department of Education (MDE) has made requirements that all school districts must meet to maintain a positive fund balance. If these are not met, the district will be classified as a deficit district, and placed into a mandatory deficit reduction program. Despite the requirements, the number of districts that end their fiscal year in deficit and or near deficit has increased. It is a very demanding task for local districts to confront financial pressures because funding is centralized at the state level under the current school funding system, Proposal A. Proposal A has given the state the authority to determine operating funding levels for local school districts. The majority of revenue is raised by the state and funding is distributed based on a per pupil foundation allowance formula that is annually determined by the state. Since it was adopted, school funding inequities across districts have been reduced, though they have 65 not been eliminated. While this system has reduced inequities, it has created problems for local districts through lack of control over their operating revenue and increased reliance on the state to determine school revenue levels. Factors like economic crisis, declining enrollment, gap in revenue and cost, and capital funding have worsened the problems. For example, during the fiscal year that ended June 30, 2010, 43 districts closed their accounts with operating deficits. The current economy that has forced the state to make cuts in K-12 education funding will lead to more school districts falling into deficit. Before school district is required to enter into the mandatory deficit reduction program or assigned an emergency manager, it is essential to have an early warning system that can alert district to the indicators associated with the variation in their fund balance. As defined in this study these indicators either positively or negatively affect fiscal stress. Previous studies do not reach a single definition for fiscal stress, but this study defines fiscal stress as having a fund balance below 8% of the total expenditures. Districts must pay for the expenses of twelve-month operations, and as of now, they receive funds for only eleven months. This established minimum of 8% or a one-twelfth minimum percent of fund balance as a share of total expenditures covers their expenses for the twelfth month. Since school districts differ in their size and total revenue they receive, fund balance as a percentage of total expenditures represents a standardized measure. The literature review centered on the conceptual and practical development of Michigan school funding system through Proposal A, details how problems arise, how fiscal stress has been defined by different entities, and methods of predicting factors of fiscal stress. Even though substantial research has found a variety of characteristics of fiscally stressed entities and provided models to estimate fiscal stress, there is no single model that is suitable for school 66 districts in general, or for Michigan districts in particular. The objectives of this study are to analyze the financial profile of Michigan public school districts, especially those districts that have been in deficit since 2001, and to investigate the indicators associated with fund balance. The indicators can be grouped into two sets of factors, those that are subject to district-level management, and those that depend on districts characteristics or circumstances that are largely outside the district’s control. The research questions designed in this study are: 1. How has the financial profile of school districts changed over time? (a) How has the number of fiscally stressed and not fiscally stressed districts changed over time? (b) To what extent have individual districts moved in and out of fiscal stress? 2. What are the indicators associated with districts’ fund balances? (a) Are the indicators within or beyond local district control? (b) Is the model developed from the above indicators stable over time? This study utilizes a ten-year data set from fiscal year 2001 to 2010 to answer the research questions. Data are collected from the Michigan Department of Education (MDE), the Michigan Center for Educational Performance and Information (CEPI), the National Center for Education Statistics (NCES), and the Michigan School Business Officials (MSBO). This study is comprised of 550 public school districts. Fund balance* (percentage of fund balance as a share of total expenditures) is the dependent variable examined with eleven independent variables. The independent variables are (1) districts characteristics which are enrollment, change in enrollment, percent of students who receive free or reduced lunch (FRL), percent of special education students, percent of English Language Learners (ELL), district per pupil foundation allowance received by the state, urban, 67 district property taxable value per pupil and (2) district management which is measured by pupilteacher ratio, average teacher salary, and business administration expenses as a percentage of current operating expenditures (COE). These variables are selected based on their importance in determining school district fund balance. Dummy variables are created for years to see if the years have significant associations with fund balance. The first part of the analysis uses descriptive statistics to answer the first research question. Districts are divided into two groups based on their fiscal status, which is based on the percentage of their fund balance as a share of total expenditures. Districts that are below 8% of fund balance as a percentage of total expenditures are coded as fiscally stressed and districts with more than 8% of fund balance as a percentage of total expenditures are not fiscally stressed. Districts are further differentiated by the number of years they have been in stress and the number of movement of being in and out of fiscal stress. Comparisons are made between the number of fiscally stressed districts and deficit districts. The second part of the analysis employs multiple regression analysis to address the second research questions. A pooled regression model is employed to analyze the data for ten fiscal years from 2001 to 2010. Since change in enrollment could be relatively small after one year, the cross-section regression model is employed with change in enrollment is calculated three years back. Finally, the models are checked for stability to estimate fund balance by plugging the intercept and coefficients from one year in another year to compare the estimated and actual fund balance. Intercepts and coefficients from fiscal year 2000 and 2005 are used to estimate the fund balance in 2010. These estimates are then compared with the actual fund balance in fiscal year 2010. The purpose is to verify the accuracy of the models from the previous two years after five and ten years. 68 5.2 Research Findings Research Question 1 This question explores the descriptive analysis of school districts fund balance for ten fiscal years from 2001 to 2010. An analysis of the descriptive analysis found the fund balance among school districts to have a significant difference (-6% to 313.86%). Enrollment, an indicator which plays an important role in the school funding, shows an extremely varied range from 2 students (Bois Blanc Pines School District) to 164,506 students (Detroit Public Schools). The fund balance shows a decline since fiscal year 2003, as the foundation allowance declined and remained for three years. In ten years, the number of districts with fund balances below than 16% has increased, while the number of districts with fund balances above 16% has decreased. This indicates an increase in numbers of districts being in fiscal stress from fiscal year 2004 to 2010. The overall health of school districts’ financial status is decreasing, though the magnitude is relatively small. During this 10-year period, 289 districts have been in fiscal stress at least once during this 10-year period. From this total, 136 districts have been in fiscal stress for five years or more. Two hundred and sixty-one districts have never been in fiscal stress, and 36 districts have been in fiscal stress for ten consecutive years. One hundred and seventy-five districts have moved to not fiscally stressed status, while 211 districts have moved to fiscally stressed status. To further explore the status of the school districts, the definition of fiscal stress is changed from 8% to 0%. Using this criteria, it is found that 15 districts have had fund balance below 0% for five years or more, and 4 districts should be on the state severe list, as they have been below 0% fund balance for eight years. Forty -three districts have regressed, moving from positive to negative fund balance, while 26 districts have progressed after moving from negative to positive fund balance. 69 In summary, 289 districts have been in fiscal stress at least once and 51 districts have had a negative fund balance at least once during the ten years. It can be concluded that many districts managed to keep their fund balance just above the zero level but not near 8% or above. Research Question 2 This question examines the association between district fund balance and factors within and beyond district control. To answer this question, a pooled multiple regression analysis is performed. Eight indicator variables are found significant in the association with fund balance: these consist of: enrollment, percent of FRL, percent of special education students, foundation allowance, urban, property taxable value, salary, and business administrative expenditures/COE. Indicators that do not have a significant association with fund balance are percent of enrollment change, percent of ELL, and pupil teacher ratio do not have a significant association with fund balance. A positive association is found between fund balance and percent of ELL students, foundation allowance, property taxable value, and pupil teacher ratio. A negative association is found between fund balance and enrollment, percent enrollment change, FRL, special education, urban, teacher’s salary, and business administrative expenditures/COE. Compared to fiscal year 2010, the first five fiscal years (2001-2005) have a significant association with the fund balance. School districts which are located in urban areas are associated with lower fund balances compared to those not located in urban areas. One of the high-cost student indicators, percent of ELL, is found to have a positive association with fund balance. Although the numbers are not significant, the number of this group of students helps increase district fund balance. The additional analyses of cross-section regression for fiscal years 2000, 2005, and 2010 pertaining to percent enrollment change is calculated over one year, and includes three years back to emphasize the change. The results have shown consistency in certain variables in 70 estimating fund balance. School districts located in urban seem to have lower fund balance than rural school districts. Looking at the factors that are beyond school district control, such as: percent of ELL students, foundation allowance, and property taxable value, these help school district increase their fund balance. Enrollment change in one year is becoming more relevant and significant lately. School districts management of spending on class size, teacher’s salary and business administrative expenditures is significantly associated with fund balance. However, pupil teacher ratio shows that bigger class sizes do not reduce district spending, thus does not help the district increase their fund balance. The test for model stability for fiscal years 2000 and 2005 shows both models are significant to estimate fund balance in the respective years, but deviate from the actual balance when five or ten years has passed. 5.3 Interpretations of the Findings Based on the findings, there were big amount of gaps in all the variables, showing that districts differ significantly in their characteristics. District’s fund balance as a percentage of General Fund total expenditures indicates that some districts have very high deficit, while some do not have problems in maintaining their fund balance. In general, district fund balance has been declining gradually for this 10-year time period (fiscal years 2001 to 2010). Districts that have declining fund balance are increasing at a higher rate than districts with increasing fund balance. The statistics indicate that enrollment and high-cost students are not uniformly distributed across districts. Enrollment as low as 2 students in one school district could affect its fund balance and fiscal stress compared to a district with a total of 164,506 students. The function of 71 enrollment is undoubtedly important in Michigan school funding to determine the revenue received from the state every year. However, the district (Detroit Public School District) that had the most number of students at one point - which has declined by half over these ten years – is not among the districts that have deficits for more than five years. As supported by the results (pooled regression) presented in this study, change in enrollment can be thought to be not significant to influence fund balance. Looking at the difference between the number of districts in deficit and fiscal stress, many districts are able to keep their fund balance in the range of 0 – 8%. These districts are employing good management strategies to cope with the financial difficulties. Yet, with the uncertain economy and declining foundation allowance in recent years, it is risky for districts to stay in this zone of fund balance. They must do their best to push their fund balance to a higher level. Placing these districts on the state watch list, and districts in deficit for more than five years on the state severe list and need state intervention could be helpful to alert the management of their fiscal status. The movement of districts in and out of fiscal stress indicates that the financial difficulties faced by school districts are still unpredictable. Even though the number of fiscally stressed districts has been less than not fiscally stressed in the period of this study, the number has yet been increasing. Experience from districts that have moved from being fiscally stressed to not fiscally stressed and districts that have never been in fiscal stress at all should be learned by other districts. Their management strategies should be examples for improvement. The research findings in this study show that district fund balance is associated with factors which are within and beyond district control. Based on the pooled regression analysis, the 72 following indicators do not have a significant association with fund balance: percent of enrollment change, percent of ELL students, and pupil teacher ratio. Though not significant, how these variables are associated with fund balance must still be considered. Generally, higher enrollment reflects larger funding received from the state. Although more expenses are incurred when there are more students, some costs per pupil are saved, which could increase district fund balance. This study proves that fund balance is inversely associated with enrollment. A theory as to why these factors are inverted could be that districts have to spend more with higher enrollment and the spending increases at a higher rate than the funding received. Thus, higher enrollment is associated with lower fund balance. When there is a downturn in economy, people will possibly move out from urban areas and cause enrollment in urban to decline, which subsequently leads to declining fund balance in urban districts. Change in enrollment is one component that is directly related to enrollment, and also to fund balance. As stated by the Citizen Research Council of Michigan Report (2010), because the marginal cost to educate a student is much less than the average cost to educate a student, a district cannot eliminate costs as quickly as it loses funding when it is losing students, and similarly, a district does not incur substantial new costs for accepting one (or even a few) choice students, but it does receive additional state aid for that student. Both enrollment and high-cost students are not uniformly distributed across districts. These groups of students do cost more to districts and most of them are concentrated in urban schools which have a higher cost of living. In an attempt to have a higher fund balance, districts would begin considering eliminating or consolidating services with their neighbor districts, especially those related to high-cost students. This study found that two of the high-cost indicators, free and reduced lunch and special education programs reduce district fund balance. 73 However, percent of ELL is unexpectedly found to help increase district fund balance. The actual costs of ELL programs vary across districts even with the same services provided. Despite this, this group of students is positively associated with district fund balance. Districts receive additional revenue for ELL while they receive per-pupil foundation allowance for the same students at the same time. This additional revenue would help district maintain their fund balance. Hence, districts should consider keeping this program, welcome more students and enjoy the benefits of a higher fund balance. Property taxable value and foundation allowance per pupil are found to help districts increase their fund balance. Foundation allowance determines the amount of funding a district receives. Even though districts are no longer allowed to levy additional mills to finance their general operating expenditures, revenues from the tax on non-homestead property remain at the local level. These local revenues comprise part of the district foundation allowance despite being offset dollar-for-dollar by corresponding decreases in state foundation aid. Thus, districts with higher property taxable value enjoy higher fund balance. However, giving more money to school districts does not necessarily raise their fund balance. The way the money is spent is important to help school districts maintain their fund balance and fiscal status. This can be achieved through the efficiency of district management on how they control class size, teachers’ salary, and business administrative expenses. As stated earlier in the paper, less spending in these areas increases district fund balance. Pupil teacher ratio, which indicates class size, is one of the district management strategies to control their spending. Though not significant, this study found that bigger class size helps district increase their fund balance. Some costs are saved with big class size, such as number of 74 teachers needed, teachers’ salary and number of classrooms. As evidenced in this study, higher salary reduces district fund balance. Since this variable is related to class size, it can be concluded that school districts that are able to reduce salary by having bigger class size can push their fund balance to a higher level. However, if districts choose this strategy as one of the ways to maintain their fund balance, they must consider the outcomes of having big classes, for instance teaching and learning, teacher motivation, and student achievement. If districts do not want to risk the outcomes, another area of spending that district could reduce is their business administrative expenditure. This study found that districts that spend more on this expenditure have lower fund balance. Districts would rather cut down their spending on business expenditures than on teacher salary, especially if they are bound by a teachers’ contract and not able to reduce their salary or increase class size. In conclusion, district fund balance is associated with factors that are within and beyond district control. Even though their fund balance would be better with efficient district management on controlling their spending in the related areas, district characteristics which are beyond district control also determine the level of their fund balance. 5.4 Policy Implications Even though the findings of this study may not be generalized to other states, this knowledge about the factors associated with district fund balance does offer valuable information to policymakers’ effort in improving district financial condition. First, the part of enrollment is undeniable in school funding. When students move from a district to another, one district loses students, and the other gains. District’s fiscal health is better with more students because they 75 can have higher fund balance, but the task of educating students must continue even with a small number of students, such as enrollment of two students in a district like Bois Blanc Pines School District. Since these two components are equally related, the state should reevaluate the policy concerning this issue. The school of choice policy would be one thing to consider if a district is to fulfill and maintain the task of educating the children in a promising financial condition. Under this policy, participating districts compete for students. This practice takes away districts’ resource of funding, though it helps raise revenues in favored districts. Continuing this policy would make districts work harder to improve the operations of their educational institutions in order to attract more students, and subsequently improve their fiscal health. Meanwhile, state should assist the losing districts to restore their financial lost and continue providing education to their children in a good fiscal health. School districts receive additional revenue from local, state and federal through the Categorical Grant for special education students. Even though these students are protected under the federal Individuals with Disabilities Education Act (IDEA), the state reimburses only 28.6% of the total costs allowed and incurred by districts. This low reimbursement rate from the state does not pay for the full amount of the actual cost incurred. The problem is worse when the number of these students is not uniformly distributed across districts. Both the total cost allowed to be reimbursed, and the actual cost incurred should be taken into account for reimbursement by the state. This consideration can help school districts reduce or eliminate financial deficits and be out of fiscal stress. Districts are classified as deficit if they have negative fund balance and required to submit a Deficit Elimination Plan (DEP) to the Michigan Department of Education (MDE). If they fail to eliminate their deficits according to the DEP, their financial affairs will be intervened 76 upon directly by the state under the Local Government and School District Fiscal Accountability Act, which is not generally favored by local management. Before districts really are far in deficit, a warning should be issued about the state of their finances. It is suggested that MDE produce a standard measure that can be a reference for local districts to alert them about their financial status. The standard could be a list of statuses, such as state watched list or state severe list based on the amount of fund balance a district has. 5.5 Scope and Limitations of Study The study covers all public school districts in the state of Michigan. Private and charter schools are not included in this study. Since education funding systems differ widely across states, the results may not be generalized to other states. Some of the data utilized in this study are long-term data that could reflect the long-term situation of Michigan school funding and some reflect only a snapshot of financial and demographic data at specific points of time. The definition of “fiscal stress” in this study was created by the author based on the literature review and the MDE requirements for school districts to have a positive fund balance at the end of the fiscal year. All these factors may limit the application of the model developed in the study to future time at different places with different policy. 5.6 Future Research The research findings in this study are based on the descriptive statistics and statistical analysis proposed by the author. It is undoubtedly that other statistical analyses will be helpful in investigating the factors associated with school district fund balance. Continued research is needed, especially with analysis that can examine how district level and time factor affect the 77 fund balance. It is hoped that future research will continue investigating and making recommendations not only to local district management, but also to the state policymakers on how school districts should use their resources efficiently to improve their financial status. 78 APPENDICES 79 Appendix A Table A-1 Michigan Public Schools with Deficits for Fiscal Year Ending June 30, 2011 District Deficit 1.
