Bank of America

(BAC) - Get Report

received its second downgrade on Friday, with Standard & Poor's equity analyst Eric Oja cutting his recommendation to hold from strong buy. Oja's downward revision follows an

earlier cut

by Wells Fargo analyst Matt Burnell.

Bank of America shares are down nearly 40% this year.

In a brief note explaining his lower recommendation, S&P's Oja cites Bank of America's second quarter 10-Q earnings report, filed with the

Securities and Exchange Commission

late Thursday. In the filing, Bank of America states that

Fannie Mae



Freddie Mac


have become "

more rigid

" in negotiations over problem mortgage-backed securities that they bought from the giant bank. As a result, Bank of America warns, its loss estimates "may materially change in the future based on factors outside our control."

Oja believes the tougher stance by the government-sponsored enterprises "could raise the costs of these claims." Bank of America sold the GSEs $1.1 trillion in mortgage-backed securities between 2004 and 2008, 11% of which have defaulted or are at least 180 days overdue.

Oja also cites a lawsuit filed late Thursday, in which New York Attorney General Eric Schneiderman asks a state court to

throw out a proposed $8.5 billion settlement

between Bank of America and 22 big institutional investors, including

Goldman Sachs

"Our previous recommendation on

Bank of America had been based on our view these costs were contained and quantifiable, but we no longer have this view," Oja writes.
