Fitch Ratingson April 27 affirmed the counterparty risk long- and short-term national ratingsat AAA(mex) and F1+(mex), respectively, of Bankof America México SA Institución de Banca Múltiple and .

The long-termratings outlook on both entities is stable.

The affirmationsare based on the support both companies will receive, should it be required, fromits ultimate holder, Bank of AmericaCorp.. Fitch believes that the ability of the parent to support itstwo Mexican subsidiaries is strong, partly due to strong synergies, a history ofcapital injections to support the subsidiaries' growth plans and the availabilityof a liquidity contingency.

Both Bank ofAmerica México and Merrill Lynch Mexico maintain high operational, commercial andfinancial integration with their parent. They also have globally established corporategovernance and risk management policies aligned with Bank of America. The banksare also characterized by a relatively stable performance albeit being lower inrecent years due to their sensitivity to market conditions, adequate capitalizationand controlled liquidity risk, Fitch noted.
