In addition, Fitch affirms the 'AA+' rating on the commission's outstanding general revenue bonds.
The Rating Outlook is Stable.
The bonds are secured by a first lien pledge of the net revenues of the commission's combined water and sewer. Additionally, the bonds carry cash-funded debt service reserve funds.
KEY RATING DRIVERS
ESSENTIAL SERVICE PROVIDER: The commission provides an essential service to a large and diverse area.
INDEPENDENT RATE-SETTING: Rates are set by the board, independent of any regulatory or other governmental oversight.
STRONG MANAGEMENT TEAM AND GOVERNANCE: Financial operations and capital planning efforts are guided by a strong and tenured management team. Governance is provided by a three-member board appointed by the city's mayor.
LARGE WHOLESALE CUSTOMER: As a large customer of the
LIMITED OPERATIONS MITIGATE LOWER FINANCIAL METRICS: Financial results are somewhat lower compared to similarly-rated systems, although the limited operations partially offset the need for more robust margins and liquidity. In addition, bondholders are afforded a lien on revenues that is prior to any payments made to MWRA.
MANAGEABLE CAPITAL PLAN: Needs are manageable and extend ongoing renewal and replacement of the system, sewer and storm separation projects, and inflow and infiltration mitigation. A 2012 consent decree will not materially impact the capital plan.
SLOWLY RISING DEBT: The issuance of the 2014 bonds coupled with the anticipated issuance of additional debt in 2017 increases the pro forma debt burden. However, debt ratios are moderate when compared to other large urban systems, and currently low debt carrying costs and fairly rapid amortization provide the commission with flexibility, and somewhat offsets the rising debt burden.
RATING STABILITY EXPECTED: The rating is sensitive to fluctuations in various credit fundamentals including financial and operating performance, capital needs and debt levels. The Stable Outlook reflects such changes are not anticipated at this time.

Population and customer account growth over the past decade have been limited, averaging about 1% annually. No revenue or usage concentration exists among the commission's customer base, the vast majority of which is residential. The system's 10 largest users include the following stable entities: the city of
LONG-TENURED MANAGEMENT AND GOVERNING BOARD
The commission's strong and consistent management is a key rating consideration. Governance is provided by a three-member board of commissioners, appointed by the mayor and subject to city council approval. Board members serve four-year staggered terms and may be reappointed as terms expire. Two of three board members have served for multiple terms. The current board chair, while in his first term with the commission, is a practicing attorney with extensive experience in the utility sector. Day-to-day operations are managed by an experienced and tenured staff, many of whom have been employed by the commission for several decades. Fitch views the working relationship between senior personnel and the board as strong.
ROBUST SERVICE AREA CHARACTERISTICS
Median household income and per capita income levels are about even with national figures but rank well below the surrounding county and state. The commission's collection rates remain consistently at or close to 100%, aided by rigorous enforcement provisions and careful oversight. Bad debt write-offs are typically negligible.
INDEPENDENT RATE-SETTING, RATES TO RISE
The commission is empowered to independently set rates and charges for water and sewer services. Management typically takes a measured approach to raising rates with annual increases that are projected to be sufficient to fund required reserves, necessary capital projects and keep pace with rising MWRA assessments (which approximate 61% of annual commission expenditures).
The commission has consistently passed manageable rate increases, which is viewed positively. However, while rates are currently affordable, additional increases are necessary to meet a projected rise in wholesale service costs and ongoing capital needs. As a result, rates are projected to rise above Fitch's affordability threshold of 2% of median household income (MHI) by fiscal 2016.
Rate hikes levied by MWRA have trended downward in recent years as capital needs decline; however, rates are still projected to rise. MWRA boosted rates on average a moderate 3.6% annually over the past five years and expects 4.6% annual increases through 2019. In turn, the commission anticipates increasing its rates by an average of about 5.1% over that period, raising the currently affordable monthly residential bill of
Fitch is less concerned about rate affordability related to the commission given the smooth implementation of rate increases to date and the relative competitiveness of existing rates for the region However, rates will need to rise consistently over the intermediate term to provide enough funding to adequately maintain system assets, meet various policies for maintaining reserves, and to offset the increasing charges from MWRA.
SOUND FINANCIAL PROFILE, STABLE RESULTS EXPECTED TO CONTINUE
The commission's financial operations are well-managed and stable, resulting in satisfactory annual debt service coverage (DSC) and sound reserves. Most financial ratios are below average for the rating, although lower metrics are somewhat offset by the commission's limited operating profile and strong fiscal oversight. Of some concern is the commission's low margins and free cash flow (FCF) ratio, which has averaged 64% of depreciation for the past five years. The low FCF ratio indicates the commission does not generate enough excess cash (after operating expenses and debt service have been paid) to replace system assets from existing rates, leading to additional borrowings and/or further rate increases.
Fiscal 2013 results were slightly lower than the two prior fiscal years with a rise in operating expense leading to a drop in DSC on the senior bonds to 1.6x from 1.8x the year prior. Coverage of all-in debt service including state loans was just satisfactory at 1.3x, resembling results recorded by the commission over the last several years. Unrestricted cash, investments and reserves totaled approximately
Pro forma financial results provided by the commission show a decline in DSC on senior lien bonds to about 1.3x by fiscal 2019 and 1.2x all-in, although the commission has typically outperformed its financial forecast. The forecast includes the debt service from the 2014 bonds, anticipated additional debt, and the proposed annual rate increases (roughly 5%).
MIXED DEBT PROFILE
At the end of fiscal 2013, the commission had
Debt levels are somewhat mixed overall. Some ratios are elevated compared to similarly rated systems, although moderate when compared to large urban systems that typically have high capital maintenance needs. Debt per customer was roughly
CAPITAL NEEDS ADDRESS SYSTEM RENEWAL; CSO PROJECTS NEARING COMPLETION

With just one sewer separation project left, the commission is nearing completion of its combined sewer overflow (CSO) remediation program. The commission benefits from MWRA's financial assistance program, in the form of grants and low-interest loans, related to CSO mitigation. Fitch notes the commission is well ahead of many large urban systems with respect to CSO mitigation, both in terms of total costs (most of which was borne by MWRA) as well as the timing of project implementation.
