CMS Bancorp, Inc. Announces March 31, 2011 Quarterly Financial Results

WHITE PLAINS, N.Y., May 11, 2011 (GLOBE NEWSWIRE) -- CMS Bancorp, Inc. (Nasdaq:CMSB) (the "Company"), the parent of Community Mutual Savings Bank (the "Bank"), announced results for the three months ended March 31, 2011 which reflect net income of $40,000, or $.02 per share, in 2011, compared to a net loss of $35,000, or $0.02 per share, in 2010.

President and CEO John Ritacco commented that "despite continued high prepayments in our mortgage portfolio, we continue to see favorable demand in the non-residential and commercial loan sectors where we experienced net loan growth of $5.8 million in the three month period ended March 31, 2011."   

Mr. Ritacco also noted that "net income improved in the three months ended March 31, 2011, compared to 2010, due to higher net interest income, lower non-interest expense and a tax credit, however non-interest income declined due to lower gains on sale of loans caused by the slower than expected residential lending activity."

Commenting on lending markets, Mr. Ritacco reported that "the first three months of 2011 saw lower demand, primarily in the residential mortgage market. We continue to experience a moderate flow of commercial business activity and we will continue with our strategic focus on diversification into higher yielding commercial, multi-family, non-residential and construction loans."

Mr. Ritacco also reported that "the Company's liquidity position remained strong at March 31, 2011, with $59.7 million of cash, cash equivalents and securities available for sale."

The Company reported that the allowance for loan losses as of March 31, 2011 was $1,169,000, up from $807,000 a year ago representing 0.65% and 0.46% of loans outstanding, respectively.  Commenting on these results, Stephen E. Dowd, Senior Vice President and Chief Financial Officer stated that "despite a weak national economy and its effect in our primary market area, the Bank did not experience any significant shift in the loan portfolio, loss experience, or other factors affecting the Bank, other than the planned growth in non-residential and commercial real estate loans and the decline in one-to-four-family mortgage loan balances. In the quarter ended March 31, 2011, we increased the allowance for loan losses by $30,000, due, in part, to economic trends, continued high unemployment, pressure on local real estate values and additions to the non-residential loan portfolio."
