-- We are placing our 'BBB+' corporate credit rating on ultimate parent
Iberdrola S.A. on CreditWatch with negative implications, which reflects the
potential for a downgrade if we lower the rating on Spain to speculative grade.
-- On Oct. 10, 2012, we lowered our sovereign ratings on the Kingdom of
Spain to 'BBB-/A-3'. The outlook remains negative.
-- We consider that Spain-based utility Iberdrola has "high" exposure to
domestic country risk as it derived about 47% of revenues from Spain in 2011.
-- Furthermore, we see a risk that Iberdrola will struggle to achieve and
maintain cash flow measures commensurate with the 'BBB+' rating in a more
challenging economic and fiscal environment.
-- We are placing our 'BBB+' corporate credit ratings on Central Maine
Power on CreditWatch with negative implications.
-- The ratings on Central Maine Power (CMP), New York State Electric &
Gas (NYSEG), Rochester Gas & Electric (RG&E), and Central Maine Power (CMP)
are all capped at the rating on the parent.
On Oct. 15, Standard & Poor's Rating Services placed its ratings on CMP,
including the 'BBB+' corporate credit rating, the 'A-' senior secured issue
rating, and the 'BBB+' senior unsecured issue ratings on CreditWatch with
negative implications. At the same time, we affirmed our 'A-2' short-term
rating on CMP.
The rating action follows the downgrade on the Kingdom of Spain to 'BBB-/A-3'
from 'BBB+/A-2' with a negative outlook, which resulted in the ratings on
ultimate parent Iberdrola S.A. being placed on CreditWatch with negative
implications. We regard the U.S. utilities, which include NYSEG, Central Maine
Power Co. (CMP), and Rochester Gas & Electric Corp. (RG&E), as effectively
under Iberdrola S.A.'s direct control, and none individually is a significant
source of cash flow for the holding company. Our ratings on NYSEG, RG&E, and
CMP therefore do not reflect significant support from Iberdrola S.A., but they
are effectively capped at the rating on the parent.
We consider that Spain-based utility Iberdrola has "high" exposure to domestic
country risk as it derived about 47% of revenues from Spain in 2011.
Furthermore, we see a risk that Iberdrola will struggle to achieve and
maintain cash flow measures commensurate with the 'BBB+' rating, mainly
adjusted funds from operations (FFO) to debt of more than 20%, in a more
challenging economic and fiscal environment. The group is due to announce its
strategic plan on Oct. 24, 2012. We will assess whether this plan will be
sufficient to counterbalance the potential downside in our forecasts as a
result of ongoing weak power market fundamentals in Spain and the U.K.,
increased political risk, delays in tariff deficit securitization, and/or a
potential electricity market reform that could have adverse consequences for
The U.S. utilities do not currently have sufficient ring-fencing measures in
place to separate the ratings from the parent. If the companies were to put
ring-fencing measures in place to sufficiently insulate them from the parent
company, they might be able to achieve ratings separation and avoid a ratings
downgrade strictly because of a ratings downgrade at the parent company.
Absent any additional insulation provisions, the utility ratings would
continue to be capped at the parent ratings.
Standard & Poor's bases its ratings on electric utility Central Maine Power
Co. (CMP) on the utility's stand-alone credit profile because its ultimate
parent company, Spanish utility holding company Iberdrola S.A. (BBB+/Watch
Neg/A-2), has assumed the debt of its parent company, Iberdrola USA
(BBB+/Watch Neg/A-2). Iberdrola S.A. is therefore directly responsible for
servicing the subholding company's debt and has unequivocally expressed its
full support for its immediate U.S. subsidiary. We regard the U.S. utilities,
which include CMP, New York State Electric & Gas Corp., and Rochester Gas &
Electric Corp., as effectively under Iberdrola S.A.'s direct control, and none
individually is a significant source of cash flow for the holding company. Our
ratings on CMP, therefore, do not reflect significant support from Iberdrola
S.A., but they are effectively capped at the rating on the parent.
Our ratings reflect CMP's low-risk business strategy and excellent business
profile and are tempered by an aggressive financial position that may come
under pressure since the company has begun expanding its transmission system
and increased its short-term financing needs. CMP's principal business
consists of its regulated electricity transmission and distribution operations
in Maine. CMP has about 600,000 customers in its service territory of about
11,000 square miles in southern and central Maine. The territory has a
population of about 1 million and contains most of Maine's industrial and
commercial centers, including the City of Portland and the Lewiston-Auburn,
Augusta-Waterville, and Bath-Brunswick areas. The company is undertaking a
large transmission project that will improve reliability and service and
interconnect renewable generation in northern Maine. The regulatory
environment in the region generally supports CMP's credit quality. CMP
operates under regulatory agreements that provide for full recovery of
electricity and gas costs, stranded costs, and returns that are in line with
industry averages. Regulatory pass-through mechanisms help to mitigate spikes
in short-term borrowing needs.
CMP's $1.4 billion Maine Power Reliability Program (MPRP), which includes 500
miles of new and upgraded transmission and four new 345-kilovolt substations
and is to be completed in 2015, will allow CMP to maintain adequate
reliability of its transmission network in compliance with federally mandated
standards. The improvements in the grid will allow for new electricity to flow
between Canada and New England and improve the power grid in Maine to
accommodate electricity from in-state generators, including the emerging
renewable generation resources. The demands of the transmission construction
will affect CMP's financial position.
CMP's financial risk profile is "aggressive" under our criteria. As of June
30, 2012, CMP generated $271 million in adjusted funds from operations (FFO)
and had total adjusted debt of $1 billion. For the same period, adjusted total
debt to total capital was about 46%, adjusted debt to EBITDA was 4.1x, and
adjusted FFO to total debt was 27%. The credit metrics reflect the
off-balance-sheet debt imputation of about $161 million, which includes a
shortfall in pension and other postretirement liability funding. While the
financial profile should benefit from approved and proposed rate increases,
the large capital spending program and need for external financing will
pressure credit protection measures, necessitating a balanced funding approach.
The short-term rating on CMP is 'A-2'. Liquidity is adequate under Standard &
Poor's corporate liquidity methodology, which categorizes liquidity in five
standard descriptors. Adequate liquidity supports our 'BBB+' issuer credit
rating on CMP. Iberdrola USA manages CMP's liquidity, and each of the U.S.
operating utilities is a joint borrower in a $600 million utility-only credit
facility maturing in 2016, with about $527 million currently available. The
company's projected sources of liquidity, mostly operating cash flow and
available bank lines, exceed its projected uses, mainly necessary capital
expenditures and debt maturities, by more than 1.2x. CMP's ability to absorb
high-impact, low-probability events with limited need for refinancing, its
flexibility to lower capital spending or sell assets, its sound bank
relationships, its solid standing in credit markets, and its generally prudent
risk management further support our assessment of its liquidity as adequate.
We base our assessment of CMP's liquidity on the following factors and
We expect the company's liquidity sources (including FFO and credit facility
availability) over the next 12 months to exceed its uses by more than 1.2x.
Debt maturities over the next year are manageable.
Even if EBITDA decreases by 15%, we believe that net sources will be well in
excess of liquidity requirements.
The company has good relationships with its banks, in our assessment, and has
a good standing in the credit markets.
In our analysis, based on information available as of June 30, 2012, we
assumed liquidity of about $800 million over the next 12 months, consisting of
projected FFO and availability under the credit facility. We estimate the
company could use roughly $665 million during the same period for capital
spending and debt maturities. CMP's credit agreement includes a financial
covenant limiting the consolidated debt-to-capitalization ratio, with which
the company was complying as of June 30, 2012.
We assign recovery ratings to first mortgage bonds (FMBs) issued by
investment-grade U.S. utilities, which can result in issue ratings that are
notched above a corporate credit rating on a utility depending on the category
and the extent of the collateral coverage. We base the investment-grade FMB
recovery methodology on the ample historical record of 100% recovery for
secured bondholders in utility bankruptcies and on our view that the factors
that supported those recoveries (limited size of the creditor class, and the
durable value of utility rate-based assets during and after a reorganization,
given the essential service provided and the high replacement cost) will
persist. Under our recovery criteria, when assigning issue ratings to utility
FMBs, we consider our calculation of the maximum amount of FMB issuance under
the utility's indenture or other legally binding limitations relative to our
estimate of the value of the collateral pledged to bondholders, management's
stated intentions on future FMB issuance, as well as any regulatory
limitations on bond issuance. FMB ratings can exceed a corporate credit rating
on a utility by up to one notch in the 'A' category, two notches in the 'BBB'
category, and three notches in speculative-grade categories.
CMP's FMBs benefit from a first-priority lien on substantially all of the
utility's real property owned or subsequently acquired. Collateral coverage of
less than 1.5x supports a recovery rating of '1', reflecting our expectation
for very high (90%-100%) recovery in the event of default, and an issue rating
one notch above the corporate credit rating.
The resolution of the CreditWatch listing on CMP is directly tied to the
outcome of the ultimate parent Iberdrola S.A.'s CreditWatch resolution. We
expect that CMP will move lockstep with the parent.
