Opinion
NEW YORK, Oct 19, 2010 -- Moody's Investors Service has assigned a Aa2 rating to Greene County's (OH)
$820,000 Sewer System Revenue Bonds, Series 2010B. Concurrently, Moody's has
affirmed the Aa2 rating on the county's outstanding sewer revenue debt,
affecting $80.2 million, including the current offering.
RATINGS RATIONALE
The bonds are secured by net revenues of the county's sewer enterprise. Proceeds
will be used to retire two bond anticipation notes maturing November 3, 2010
that were originally issued for sewer system improvements. The Aa2 rating is
based on the system's solid financial operations with recent declines in
economically-sensitive connection charges; 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 sewer 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 seven municipalities
with treatment plants located in Beavercreek (Aa2), Sugarcreek Township (Aa2),
Cedarville and Clifton. The system also provides services to customers in
Montgomery (Aa1) and Warren (Aa1) counties, and these customers account for
approximately 28% of total connections. The utility provided sewer
collection and treatment services to over 30,000 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 5% of
usage. Sewer usage has been relatively stable over the last five years,
with fluctuations primarily due to weather patterns as sewer fees are
assessed for most customers based on water usage.
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 sewer
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 connection charges 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 recent rate increases. In fiscal 2009, Moody's
calculation of the system's net working capital stood at $6.4 million, or a
solid 109.6% of operating and maintenance (O&M) expenses. Unrestricted
cash represented $3.5 million, or a satisfactory 22.6% of operation and
maintenance expenses, above the utility's informal policy to maintain cash
reserves above 15% of operating expenditures. Connection charges, which
represented nearly 10% ($1.8 million) of operating revenues in 2008, declined by
69% from fiscal 2008 to fiscal 2009. Connection charges are typically
generated through new construction, and the slow-down in growth in 2009 led to
the reduction in fees. In response to the revenue decline, the utility enacted a
5% rate increase in January 2010. The county also restructured its outstanding
sewer revenue and general obligation debt supported by sewer utility revenues to
reduce debt service payments from 2010 to 2015. For fiscal 2010, the
utility currently plans to have surplus operations and increase its net
working capital levels through an expected $100,000 to $300,000 surplus
following payment of debt service.
The utility's operating ratio is healthy with operations and maintenance only
constituting 38.4% of revenues. Nevertheless, the system's debt service coverage
ratio has declined due to the high level of debt service supported by the system
and the system's reliance on economically-sensitive connection charges. In
fiscal 2009, the utility's revenue debt service coverage stood at a
satisfactory 1.37 times coverage. For total debt obligations, which includes
revenue debt, state loans, and general obligation debt supported by water
utility revenues, coverage fell to 1.08 times in 2009. Due to the rate increase
implemented in 2010 and an additional increase planned for 2011, the utility
expects 2011 debt service coverage on post-sale debt will be greater than
2009 coverage levels. Favorably, rate setting authority rests with the Greene
County commissioners and no external approval is required. The system may also
collect delinquent fees by applying them to customer property tax bills, helping
to ensure high rates of collection. 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.
SATISFACTORY LEGAL PROVISIONS WITH FULLY FUNDED DEBT SERVICE RESERVE FUND
Legal protections included within the utility's 1993 trust agreement
and supplemental agreements provide satisfactory security for bondholders. The
rate covenant and additional bonds test stipulate that the sewer
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 sewer
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 include the Series 2003 bonds, 2005 bonds, 2007A
and 2007B bonds and 2010 bonds. All of the parity bonds except for Series 2007B
have cash-funded debt service reserve funds. Series 2007B has a debt service
reserve fund covered by an MBIA (senior unsecured B3/negative outlook) surety
policy.
AVERAGE DEBT RATIO; NO ADDITIONAL CAPITAL BORROWING PLANNED
Officials report that recent major upgrades to the system's treatment plants
will cover capacity for twenty years and no major capital needs are expected in
the medium term. The last major capital improvement to the system involved
upgrades at the Sugarcreek treatment facility and was completed over the last
year. Approximately 60% of wastewater flow processed at the facility comes from
Montgomery County, and the utility expects to receive funds from Montgomery
County to support debt service on the state loans that were borrowed to fund the
upgrades. At the end of fiscal 2009, the system's debt ratio was at 45.4% of net
fixed assets and net working capital. Principal amortization on the system's
revenue debt is below average, with 53% repaid within ten years, though matches
the useful life of the assets being financed. We expect the system's debt will
remain manageable due to the lack of borrowing plans in the medium term.
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
