Fitch Downgrades EME and MWG's IDRs to 'C' From 'CC'

  Fitch Downgrades EME and MWG's IDRs to 'C' From 'CC'

Business Wire

NEW YORK -- November 20, 2012

Fitch Ratings has downgraded Edison Mission Energy (EME) and Midwest
Generation LLC's (MWG) Long-term Issuer Default (IDR) ratings to 'C' from
'CC'. Fitch has also affirmed EME's senior unsecured debt and recovery ratings
at 'C' and RR5, respectively. Fitch notes that MWG's secured working capital
facility expired in June 2012. Approximately $3.7 billion of long-term, senior
unsecured debt is affected by the rating action.

The ratings of Edison International (EIX) and Southern California Edison (SCE)
are not affected by the rating action. EIX has managed EME on a stand-alone
basis. Fitch does not expect any direct financial exposure to result from the
anticipated EME bankruptcy. Similarly, SCE operations are separate from EIX
and EME consistent with prevailing California Public Utilities Commission
regulations.

Fitch considers 'C' category credits to possess exceptionally high levels of
credit risk. The 'C' category also indicates default is imminent or
inevitable, or the issuer is in standstill.

Conditions indicative of a 'C' category rating include:

--That the issuer has entered into a grace or cure period following
non-payment of a material financial obligation;

--The issuer has entered into a temporary negotiated waiver or standstill
agreement following a payment default on a material financial obligation; or

--Fitch Ratings otherwise believes a condition of 'RD' (Restricted Default) or
'D' (Default) to be imminent or inevitable, including through the formal
announcement of a distressed debt exchange.

On Nov. 15, 2012, EME filed form 8k with the Securities and Exchange
Commission indicating that the company elected not to make interest payments
totaling $97 million on senior unsecured debt scheduled to mature in 2017,
2019 and 2027. EME bond documents provide a 30-day grace period, which expires
on Dec. 17, 2012. If the interest payment is not made prior to the end of the
grace period on December 17th, the company is likely to file for Chapter 11
protection under the U.S. Bankruptcy Code.

An EME bankruptcy would be an event of default under Midwest Generation, LLC's
Powerton-Joliet lease.

'C' is the lowest rating assigned to debt instruments in Fitch's rating scale.
The 'RR5' Recovery Rating is based on a recovery level of approximately 11% to
30% of principal claims by senior unsecured creditors.

Additional information is available at 'www.fitchratings.com'. The ratings
above were solicited by, or on behalf of, the issuer, and therefore, Fitch has
been compensated for the provision of the ratings.
