BofA CEO "comfortable" with bank's investments

May 21 (Reuters) - Bank of America Corp is "very comfortable" with the composition of its corporate investment portfolio, which is invested mostly in government-guaranteed mortgage bonds and U.S. Treasury bonds, Chief Executive Officer Brian Moynihan said at an investor conference on Monday.

Moynihan was asked about the bank's investments following JPMorgan Chase & Co's disclosure this month that it lost $2 billion or more on a trading strategy in its Corporate Investment Office. Bank of America buys insurance-like protection on some loans to large companies, but doesn't make broader hedging bets at the corporate level, he said.
