WASHINGTON — Two failures — one in Illinois and another in Nevada — cost the Federal Deposit Insurance Corp. about $63 million Friday night.

The Office of the Comptroller of the Currency closed the $187 million-asset Western Springs National Bank and Trust in Western Springs, Ill. Later, state regulators closed the $145 million-asset Nevada Commerce Bank in Las Vegas.

The FDIC found buyers for both institutions. Heartland Bank and Trust Co. in Bloomington, Ill., agreed to assume all of Western Springs' $182 million in deposits. Heartland will also acquire roughly all of the failed bank's assets, and share losses with the FDIC on just over $100 million of those assets. The failure was estimated to cost $31 million.

Meanwhile, Nevada Commerce's operations were sold to Los Angeles-based City National Bank. The buyer agreed to pay a 0.7% premium for all of the failed bank's $136 million in deposits, and will also acquire roughly all of its assets. City National and the FDIC agreed to share losses on $111 million of those assets. Nevada Commerce’s failure was estimated to cost the Deposit Insurance Fund about $32 million.

The frequency of failures this year continues to cool down from the nonstop activity of 2009 and 2010. Friday night’s closures, which brought the 2011 total to 28, followed a previous week in which there were none. Just three banks were shuttered in all of March, and last month saw only one Friday with multiple seizures.
