Fitch Ratings has assigned an 'AAA' rating to the following Weslaco Independent School District, Texas unlimited tax (ULT) bonds:

--$14.965 million ULT refunding bonds series 2015A;

--$18.89 million ULT refunding bonds series 2015B.

The 'AAA' rating is based on a guarantee provided by the Texas Permanent School Fund (PSF). (For more information on the Texas PSF see 'Fitch Affirms Texas PSF Rating at 'AAA'; Outlook Stable', dated Sept. 4, 2014.)

The bonds are scheduled for negotiated sale on Feb. 9. Proceeds will be used to refund a portion of the district's outstanding debt for annual cost savings.

Fitch also assigns an underlying rating of 'AA-' to the series 2015 A&B bonds and affirms the 'AA-' underlying rating on the district's $61.89 million ULT bonds outstanding.

The Rating Outlook is Stable.

SECURITY

The bonds are payable from an unlimited property tax levy and also carry the Texas PSF guarantee.

KEY RATING DRIVERS

SATISFACTORY FISCAL CUSHION: The district retains a satisfactory level of operating reserves and liquidity. Additional flexibility is evidenced by the district's significant general fund transfers for capital outlays.

STABLE TAX BASE: The district is part of the broad and growing Rio Grande Valley economy and continues to register modest taxable assessed value (TAV) gains; the area housing market has remained fairly stable.

BELOW-AVERAGE SOCIO-ECONOMIC PROFILE: Income levels and tax base wealth are low while unemployment and poverty rates are elevated.

DECLINING ENROLLMENT: A trend of enrollment growth was replaced by declines in fiscals 2014 and 2015, due in part to increased competition from area charter schools. Continued declines would reduce the district's state revenues and could become a notable financial pressure.

MANAGEABLE DEBT BURDEN: Overall debt ratios are moderate to high, having increased in recent years due to new issuance by overlapping entities. Carrying costs for the district's long-term liabilities are very low as the result of significant state subsidies.

RATING SENSITIVITIES

FINANCIAL FLEXIBILITY: The district's currently sound financial operations and reserves are an important offset to the below-average resource base. Any deterioration of financial flexibility would likely result in negative rating pressure.

CREDIT PROFILE

Weslaco ISD is located in Hidalgo County near the U.S.-Mexico border and between the cities of McAllen and Harlingen. The city of Weslaco is the district's major commercial center and had an estimated 2013 population of 37,093.

FISCAL CUSHION MAINTAINED

The district's current level of financial flexibility is the key credit characteristic supporting the 'AA-' rating. The district has maintained an unreserved/unrestricted general fund balance at 11%-16% of spending in the past five fiscal years while making significant general fund contributions for capital projects.

Strong property tax collections and savings from a conservative payroll budget also contributed to a net general fund operating surplus after transfers of $3 million (1.8% of spending) despite paygo capital spending of $1.6 million. The unrestricted general fund balance for fiscal 2014 was $27.1 million or 16.2% of expenditures, well in excess of its $16 million (9.6%) informal target. Liquidity was sound with general fund cash equaling nearly three months of expenditures.

The district's $156.1 million fiscal 2015 operating budget reflects a $2.7 million payroll increase for a district-wide pay hike. The budget also includes $4.6 million in one-time expenditures and transfers out for capital, resulting in a planned drawdown of $5.2 million for an ending general fund balance of $22 million or 14.1% of expenditures. Year-to-date enrollment is slightly lower than budgeted and will impact state aid to the district. However, management budgets conservatively for expenditures, and expects that cost savings will allow the district to meet its budgeted results for fiscal 2015.

UNCONVENTIONAL TAX RATE STRUCTURE

Weslaco ISD voters approved a tax rate restructuring in fiscal 2012 that maintained the total tax rate of $1.14 per $100 of TAV while shifting the entire debt service tax rate to the general fund. The net effect was to generate an additional roughly $1 million annually under provisions in the state's funding formula that more heavily subsidize general fund taxing effort.

Annual ULT debt service of $6.3 million is now repaid via annual transfers from the general fund. Fitch recognizes the slight revenue advantage to the district but notes this unconventional taxing structure could be subject to legislative or statutory changes. However, credit concerns are mitigated by management's ability to reverse the tax rates if necessary.

LIMITED LOCAL ECONOMY PART OF BROADER MCALLEN MSA

The district is part of the growing McAllen-Edinburg-Mission metropolitan statistical area (MSA) that is located just seven miles north of the Mexican border and the Mexican city of Reynosa, Tamaulipas. Agribusiness and international trade with Mexico are major economic components of the region. This is evidenced in the regional maquiladora program, where manufacturing and assembly occurs in plants located in Reynosa and warehouse and distribution are handled in the U.S. In addition, the stable government, education, and health service sectors make up a combined 50% of the MSA's non-farm labor force; top employers in the city of Weslaco include the school district and a local hospital.

The non-farm unemployment rate in the city is elevated relative to the state and nation. The November 2014 unemployment rate dropped to 7% from the 10.3% recorded a year prior, reflecting the combined effect of employment growth and declines in the labor force. District wealth and income levels are well below average, the poverty rate is double that of the state, and educational attainment rates are very low.

MODEST TAX BASE GROWTH; FLAT ENROLLMENT

The mostly residential tax base continues to appreciate in value due to positive reappraisal and modest residential and commercial development underway. Fiscal 2015 TAV climbed 2.2% to $1.9 billion, and continued stability in the tax base is likely based on trends of modest economic growth.

Enrollment growth has flattened due to competition from a nearby charter school system. A historical growth trend was replaced by a modest decline in fiscal 2014 and year-to-date enrollment for fiscal 2015 is down by 2.4% from the prior year. Management projects that this stagnant trend of flat to modest declines will continue in the near term. The district's conservative budgeting practices and history of strong financial performance offset immediate budgetary impact, but prolonged enrollment declines could place significant pressure on district operations.

MANAGEABLE LONG-TERM LIABILITIES

The district's debt is heavily funded by the state. Overall debt is high at 7.7% of the market value but debt per capita is moderate at $2,683. The increase in recent years reflects overlapping issuances by Hidalgo County, a community college district, and two cities. The pace of principal amortization remains average with this issuance at 54% retired in 10 years. The district has no remaining ULT debt authorization and no near-term borrowing plans.

The district's pension liabilities are limited to its participation in the state pension plan administered by the Teacher Retirement System of Texas (TRS). The district's annual contribution to TRS is determined by state law, as is the contribution for the state-run postemployment benefit healthcare plan. Including debt service, pension, and OPEB contributions, carrying costs were a modest 5.1% of fiscal 2014 governmental fund spending, benefitting from the state's strong subsidy for pensions currently in place. However, school districts are susceptible to future funding changes by the state as evidenced by a new, relatively modest employer contribution requirement of 1.5% of salary effective fiscal 2015.

TEXAS SCHOOL FUNDING LITIGATION

A Texas district judge ruled in August 2014 that the state's school finance system is unconstitutional. The ruling, which was in response to a consolidation of six lawsuits representing 75% of Texas school children, found the system inefficient, inequitable, and underfunded. The judge also ruled that local school property taxes are effectively a statewide property tax due to lack of local discretion and therefore are unconstitutional.

Following a similar ruling in February 2013, the judge granted a motion to reopen the lawsuit four months later after state legislative action that partially restored state funding levels and made other program changes. Fitch expects the state will appeal the latest ruling to the state supreme court. If the state school finance system is ultimately found unconstitutional, the legislature will be directed to make changes to the system to restore its constitutionality. Fitch would view positively any changes that include additional funding for schools and more local discretion over tax rates.
