SECURITY

KEY RATING DRIVERS

HEALTHY FINANCIAL PROFILE: Management's conservative budgeting practices, recurring revenue increases and expenditure controls support Mercer's recent growth in reserves to levels considered adequate by Fitch.

BROAD AND DIVERSE ECONOMY: The county's diverse economy benefits from the presence of major higher education and healthcare institutions, as well as large pharmaceutical and financial services companies. Princeton University, along with Rider and The College of New Jersey, contribute to a well-educated work force and provide for research facilities and expertise for area businesses.

ABOVE-AVERAGE ECONOMIC INDICATORS: Income and employment metrics are strong evidenced by high wealth indicators and unemployment rates below state and national averages. Job growth has been exceptionally strong recently compared to other New Jersey counties.

MANAGEABLE DEBT AND CAPITAL NEEDS: Overall debt levels are moderate and should remain so based on future borrowing and capital needs and the rapid retirement of outstanding debt. Rising costs associated with pension and healthcare are the drivers of spending growth; however, the cost of servicing these long-term liabilities in addition to debt is still considered moderate.

RATING SENSITIVITIES

STABLE FINANCIAL PERFORMANCE: The 'AA+' rating reflects Fitch's expectation that economic and debt fundamentals will remain largely stable and that the county will continue to manage its finances to maintain structural balance and an adequate reserve cushion. The rating is sensitive to performance outside of Fitch's stated expectations.

CREDIT PROFILE

Mercer County is situated in the center of the state equidistant between New York City and Philadelphia. The county has an estimated 2014 population of 370,414 which has grown 5.6% since 2000. The capital city of Trenton and Hamilton Township account for just under half of the county's population. The county's above-average wealth levels reflect in part the several wealthy suburban communities located within the county, including Princeton, West Windsor, Hopewell and Pennington. Median household income registers 103% of the state and 139% of the national levels. Such levels are skewed downward in part due to Trenton's below average wealth levels (roughly 50% of state levels) and high poverty rate (26.5% for 2013).

Unemployment as of November 2014 was 4.6% in the county down notably from a high of 7.9% in 2010 and remains below state (5.6%) and national (5.9%) levels. County employment growth recovered in 2012 rising 0.9%, and again in 2013 by 1.2% and 1.5% in 2014, reflective of strong hiring in professional/business services and a recovering real estate market. Additionally, the opening by Amazon of a new warehouse in Robbinsville last year contributed to 1,400 new jobs. Overall employment growth in the Trenton-Ewing NJ metropolitan statistical area (MSA) had the highest percentage change year-over-year through November 2014 out of all MSAs in the state according to IHS, Inc.

The county features a broad and diverse economic base with representation from the higher education, health care, pharmaceuticals, telecommunication and financial services sectors. State government dominates Trenton's economy with the state employing 22,500 employees or just over 10% of total 2014 county employment. Other substantial employers include Princeton University (6,011 employees), Bristol Myers Squibb (6,000), Capital Health Systems (3200), and NJ Manufacturing Insurance Co. (2,478).

The county has a large tax base of $42 billion on an equalized basis in 2014 and equals a solid $114,000 per capita. The tax base experienced moderate declines due to the housing downturn but is projected to increase modestly in 2015 due to a rebound in housing prices and some commercial development. Home prices throughout the county are showing growth of 4.4% on a year-over-year basis through December 2014 according to Zillow. The county's tax base is diverse with the 10 largest taxpayers representing only 5% of 2013 taxable value.

CONSERVATIVE FISCAL MANAGEMENT LEADS TO SOUND FINANCIAL PERFORMANCE

The county has a history of generally stable operating results supported by careful expenditure management and consistent moderate tax rate increases. The implementation of the state's new 2% tax levy cap in fiscal 2011 created some budgeting challenges but management has made adjustments to maintain service levels and restore reserves to adequate levels. The 2% tax levy cap excludes payments for debt service, capital improvements, healthcare cost increases in excess of 2% from the prior year and pension costs. Additionally, any new growth in the tax base is excluded from the calculation and any unused portion of the levy can be carried forward for three years. The state also passed a law in 2011 that limits overall annual employee contract increases to 2% per year which has helped the county control labor costs.

Fiscal 2013 results showed a $3.8 million (1.2% of spending) operating surplus increasing fund balance to $20.1 million or 6.5% of current fund spending. The positive results reflected in part positive overall revenue variances and medical costs savings. The county uses a cash/modified accrual basis of accounting in accordance with state requirements as opposed to GAAP accounting. The comparison of fund balance levels to those issuers who use GAAP accounting is usually lower due to the typically larger current fund expenditure base and the requirement to carryover unexpended appropriation reserves for an additional year. Fund balance levels have fluctuated from a high of 9% in 2008 to as low as 4.3% in 2008 when the recession occurred. Management has indicated its goal is to maintain reserves at close to the 7% level to maintain flexibility. The county maintains other reserve balances, although with restricted purposes, including open space tax funds ($25 million at fiscal end 2014), as well as insurance ($3 million) and capital reserves.

The original 2014 budget totaled $300 million and included a 2.9% tax levy increase. The tax levy generates approximately 85% of current fund budgeted operating revenue. The high percentage of tax revenues provide for better predictability and stability of revenues each year. Property tax revenues are insulated from declines in tax base valuation since the state's tax cap laws are based on the prior year's levies allowing for tax rate adjustments to remain revenue neutral. Tax collections for the county are guaranteed as taxes are collected at the local levy and remitted in full to the county on a quarterly basis. The budget appropriates $12 million of fund balance, up from $10.6 million the prior year. The county has a historical practice of using close to 50% of fund balance to balance its budget but tends to not have to use it due to conservative budget practices. Major expenditures include employee salary, healthcare and pension costs. Management is projecting a $1.5 million operating surplus which would increase fund balance to $21.6 million or approximately 7% of spending.

MODERATE LONG-TERM LIABILITIES; RAPID DEBT AMORTIZATION

Overall debt metrics are moderate at 3.3% of market value and $3,795 per capita. These ratios include county-guaranteed debt issued by the Mercer County Improvement Authority. Debt amortization is fast at approximately 72% over 10 years. Management has indicated its expectation for additional debt is approximately $20 million-$30 million per year for capital and maintenance costs which is consistent with its history of past borrowings. Despite the rapid payout of debt the county's carrying charges inclusive of pension and other post-employment benefits (OPEB) remains manageable accounting for an estimated 19% of spending.

All employees and retirees participate in the state administered Police and Firemen's Retirement System (PFRS) or the Public Employee's Retirement System (PERS). The funded status of the PFRS and PERS was 74% and 77% respectively, as of June 30, 2013. Using Fitch's conservative 7% investment rate of return, the funded levels decline to an estimated 67% and 70%, respectively. The county fully funds its pension contribution as required by the state plans and paid a combined $14.4 million to the plans in 2013. OPEB is offered through the state's plan and the county makes pay-as-you-go payments as required by the state. The county paid $7.8 million in 2013.
