Foreclosures and short sales continue to impact the economy. The nation’s largest bank reported this morning that it lost $2.2 billion in 2010, or $0.37 per diluted share. During the fourth-quarter period, Bank of America posted a net loss of $1.2 billion, or $0.16 per share, which included a goodwill impairment charge of $2.0 billion in its home loans and insurance division. Had it not been for this charge, the company says it would have earned $756 million in Q4.
