Opinion
NEW YORK, Oct 19, 2010 -- Moody's Investors Service has assigned a Aa2 rating to Greene County's (OH) $7.2
million Water System Revenue Bonds, Series 2010. Concurrently, Moody's has
affirmed the Aa2 rating on the county's outstanding water revenue debt,
affecting $30.6 million, including the current offering.
RATINGS RATIONALE
The bonds are secured by net revenues of the county's water enterprise. Proceeds
will be used to retire four bond anticipation notes maturing November 3, 2010
that were originally issued for water system improvements. The Aa2 rating is
based on the system's solid financial operations experiencing declines in tap-in
fee revenues; satisfactory debt service coverage ratios following a rate
increase; sufficient legal provisions; and an average debt ratio with no
additional borrowing planned.
MODERATELY-SIZED AND STABLE CUSTOMER BASE IN GROWING GREENE COUNTY; BENEFITS
FROM PRESENCE OF WRIGHT PATTERSON AIR FORCE BASE
Located in southwestern Ohio directly adjacent to the city of Dayton
(Aa2/stable outlook) and encompassing the Wright Patterson Air Force Base,
Greene County's (Aa2) local economy is intertwined with both the city of
Dayton and the air force base. The water utility's service area primarily covers
the western portion of the county near both Dayton and the air force base. The
utility serves the unincorporated areas of the county and the cities of
Beavercreek (Aa2), Kettering (Aa2) and the village of Cedarville. The utility
provided water treatment and distribution services to 16,675 customer accounts
in 2009 and the number of customers has been increasing modestly every
year, though has slowed in recent years. Favorably, the utility's top customers
are relatively stable entities, primarily higher education institutions,
apartment complexes, and assisted living facilities. The top nine customers
comprise a modest 4% of usage. Water usage has been relatively stable over the
last five years, with fluctuations primarily due to weather patterns.
In recent years, the system has benefited from trends of suburbanization in the
Dayton metropolitan area and growth at the Wright Patterson Air Force Base
(27,000 employees). While the Dayton area has experienced challenges due to the
loss of National Cash Register, Delphi, and General Motors (corporate family
rating Ba2/stable outlook) over the last five years, Wright Patterson Air Force
Base has continued to see growth as a result of the 2005 Base Realignment and
Closure (BRAC) recommendations. The base is set to add an additional
1,200 military and civilian positions by September 2011, and the expansion is
expected to lead to additional regional jobs at suppliers and
related businesses. We expect the customer base will remain stable as the water
utility is well-positioned to benefit from growth at the air force base as the
economy recovers.
RECENT RAPID DECLINES IN BUILDING-RELATED FEES REDUCED DEBT SERVICE COVERAGE;
COVERAGE EXPECTED TO IMPROVE FOLLOWING RATE INCREASES
Despite a large decline in tap-in fee revenues in 2009, we expect the system's
financial operations to remain stable in the near term due to a solid net
working capital balance and conservative revenue projections going forward. In
fiscal 2009, Moody's calculation of the system's net working capital stood at
$6.9 million, or a solid 138.1% of operating and maintenance (O&M) expenses.
Unrestricted cash represented $2 million of total net working capital, or a
satisfactory 28.5% of O&M expenses, above the utility's informal policy to
maintain a minimum of 2.5 months of operating expenditures in cash
reserves. Tap-in fees and connection charges, which represented nearly 20% ($2
million) of operating revenues in 2008, declined by 50% from fiscal 2008 to
fiscal 2009. Tap-in fees and connection charges are typically generated through
new construction, and the slow-down in growth in 2009 led to the reduction in
fees. Favorably, management has conservatively budgeted for both
economically-sensitive revenue streams to show further modest decline in 2010
and to remain relatively flat going forward. In response to the revenue decline,
the utility enacted a 3% rate increase in February 2010. The county also
restructured its outstanding general obligation debt, including debt supported
by water utility revenues, to reduce debt service payments from 2010 to 2015,
which lowered the water utility's obligations. For fiscal 2010, the utility
currently expects to have surplus operations and increase its net working
capital levels through an estimated $300,000 surplus following payment of debt
service.
In fiscal 2009, the utility's revenue debt service coverage stood at a solid
1.58 times coverage. For total debt obligations, which includes revenue debt,
state loans, and general obligation debt supported by water utility revenues,
coverage fell to 1.03 times due to the reduction in tap-in fees. Projected
fiscal 2011 debt service coverage (including debt service on the current
issuance) yields an adequate 1.20 times debt service coverage for revenue debt
and 1.0 times debt service coverage for all debt, though we note that the system
expects to enact an additional rate increase in January 2011 which will raise
coverage levels. Favorably, rate setting authority rests with the Greene County
commissioners and no external approval is required. While the county has
demonstrated an ability and willingness to leverage its rate setting authority
to strengthen coverage ratios, a failure to return to historic coverage
levels could affect the utility's long-term credit quality, particularly given
the county's reliance on economically-sensitive connection charges and tap-in
fees.
SATISFACTORY LEGAL PROVISIONS WITH FULLY FUNDED DEBT SERVICE RESERVE FUND
Legal protections included within the utility's 1991 trust agreement and Fifth
Supplemental Agreement provide satisfactory security for bondholders. The rate
covenant and additional bonds test stipulate that the water utility maintain
rates at levels to ensure a sound 1.20 times debt service coverage on all
outstanding revenue debt. In addition, the covenants require that the district
maintain rates at sum sufficient levels to cover annual debt service on all
outstanding debt backed by revenues of the water utility, including general
obligation debt and state loans. The trust agreement also requires a debt
service reserve fund fully funded with bond proceeds to meet the lesser of
maximum annual debt service, 1.25 times annual debt service, or 10% of total par
amount on the current issuance. The utility's additional senior lien bonds,
which include the 2007A bonds, 2004 bonds, and 2001 bonds, all have debt service
reserves covered by surety policies issued by FSA (senior unsecured A3/negative
outlook) and MBIA (senior unsecured B3/negative outlook).
AVERAGE DEBT RATIO; NO ADDITIONAL CAPITAL BORROWING PLANNED
Officials report that recent major upgrades to the system's treatment plants
will cover capacity for ten to fifteen years and no major capital needs are
expected in the medium term. With a rated capacity of approximately 8.4 million
gallons per day (MGD), the existing infrastructure provides ample capacity as
maximum daily flow in 2009 was 6.81 MGD. At the end of fiscal 2009, the
system's debt ratio was at 50.9% of net fixed assets and net working capital,
and principal amortization on the system's revenue debt is rapid, with 77%
repaid within ten years. Given the system's lack of additional borrowing needs
and rapid principal amortization, we expect the debt burden will remain
manageable.
WHAT COULD MOVE THE RATING - UP
-Substantial improvement in debt service coverage
-Substantial improvement in net working capital and liquidity
-Strong expansion of customer base
WHAT COULD MOVE THE RATING - DOWN
-Deterioration in annual debt service coverage below similarly rated enterprises
-Significant leveraging of net revenues above affordable levels
