The Obama administration has begun monitoring the high-level board meetings of nearly 20 banks that received emergency taxpayer assistance but repeatedly failed to pay the required dividends, according to Treasury Department officials and documents. And it may soon install new directors on some of their boards. The moves come as the number of banks that failed to make at least one dividend payment to the government rose to 132 in the last quarter. These "deadbeats," as they are sometimes called, are virtually all community lenders and collectively received billions of dollars in taxpayer assistance. In addition to those firms, seven others have failed, resulting in the total loss of the government's investment.
