Fitch Rates Metropolitan Water District of Southern California's $322MM Water Revs 'AA+'.

SAN FRANCISCO -- Fitch Ratings has assigned an 'AA+' rating to Metropolitan Water District of Southern California's (Metropolitan) following bonds:

* $100 million water revenue refunding bonds, series 2007A-1;

* $122 million water revenue refunding bonds, series 2007A-2;

* $100 million water revenue bonds, 2006 authorization, series B-1.

The three series of bonds will be structured as auction rate securities and are scheduled to sell via negotiated sale on June 5, 2007. Broker dealers for the series A-1 bonds include Goldman Sachs and Bank of America, for the series A-2 bonds Morgan Stanley and De La Rosa, and for the series B-1 bonds Citigroup and UBS.

Fitch has also affirmed the 'AA+' long-term rating on Metropolitan's approximately $4.2 billion in outstanding water revenue bonds and the 'AAA' long-term rating on Metropolitan's approximately $359 million on general obligation (GO) bonds. The Rating Outlook on all the bonds is Stable.

Revenue bonds are secured by net operating revenues of Metropolitan's water system. GO bonds are secured by Metropolitan's ability to levy unlimited ad valorem taxes on its $1.8 trillion tax base. Bond proceeds includes approximately $100 million of new money that will be used to fund ongoing projects in Metropolitan's capital plan and $222 million of refunding bonds that will refund all of Metropolitan's outstanding series 2001B-1 and 2001B-2 bonds.

The 'AA+' rating reflects credit strengths that include the essentiality of the service provided, consensus regarding Metropolitan's role as the region's wholesale water supplier, a very strong financial position even with a recent decline in debt service coverage levels, effective and conservative management decisions, and a robust, diverse and growing service area. Metropolitan serves as the regional coordinator for the growth that will require additional water supplies, largely consisting of reclamation, conservation, and potentially desalination.

Credit concerns focus on the sizeable capital costs related to long-term water supply, storage and treatment costs. Metropolitan's five-year capital investment plan (CIP) totals $2 billion and 76% is expected to be funded from bond proceeds. Over the next five years, Metropolitan expects to add another $1.2 billion to its current $4.2 billion in outstanding debt, including the $100 million of series B-1 bonds (new money). Long-term cost pressure will accompany Metropolitan's CIP and operating cost increases. Cost pressure at Metropolitan and regional pressure by its members to limit rate increases will likely continue to be a challenge.

Financial performance in fiscal 2006 was weaker than previous years with debt service coverage of 1.85 times (x) and fixed charge coverage of 1.27 times (x). The decline is the result of increased state water project costs and debt service costs associated with the capital plan. Including an $87 million transfer in from the rate stabilization fund, coverage was more in-line with historical levels at 2.33x and fixed charge coverage of 1.6x. Debt service coverage (without any rate stabilization fund transfers) is projected to range between 1.67x and 2.2x over the next five years. Fitch views the projected decline in debt service coverage as acceptable for the current rating, given Metropolitan's fundamental credit strengths, the temporary nature of the declines, and the board's history of demonstrated support for cost recovery through rates, when necessary.

Metropolitan is a wholesale water provider to 26 member public agencies. Its vast service area includes over 18 million residents, or about 85% of the population in Los Angeles, Orange, Riverside, San Bernardino, San Diego, and Ventura counties. While member agencies are not required to purchase Metropolitan's water, Fitch does not view competition as a credit concern given the practical lack of other supplies.

Metropolitan provides between 40% and 60% of the service area's water, depending on water conditions, and works with the State Department of Water Resources (DWR) on the development and acquisition of long-term water supply for the region. Metropolitan's supply is derived from two sources - Northern California's Bay/Delta water via the state water project (SWP), which provided approximately 75% of its water supply in 2006, and the Colorado River via the Colorado River Aqueduct, which provided the remaining 25%.

Fitch notes that there is currently a court case in progress that could significantly impact the SWP water supply. The California Department of Water Resources (DWR), which operates SWP, has been ordered to cease operation of the project by mid-June of 2007 or obtain an incidental take permit as required by the Endangered Species Act. On May 7, 2007, DWR appealed the court's decision and received an automatic stay of the order to cease operations. It appears that DWR will work toward receiving a permit while the appeal process is ongoing.

The loss of SWP water would be a negative credit development for Metropolitan and its members. Should this unlikely event occur, Metropolitan's drought resource management plan could be implemented. The plan includes the reduction of deliveries to agricultural water users, curtailment of all groundwater replenishment, and use of stored reserves approximately equal to Metropolitan's annual demand.
