Operating Results

The Company reported first quarter 2012 net income of $3.9 million, or $0.13 per diluted share, compared to fourth quarter 2011 net income of$4.0 million , or $0.14 per diluted share. For the first quarter 2011, the Company recorded a net loss of $1.0 million , primarily as a result of a cash contribution to the Rockville Bank Foundation, Inc. (the "Foundation") totaling $5.0 million pre-tax during that quarter. Net income for the first quarter 2011 excluding the Foundation contribution (after-tax) was $2.2 million, or $0.07 per diluted share. This 77.4% increase year-over-year, excluding the Foundation contribution, resulted from continued organic growth in both commercial loans and low cost core deposits during the first quarter 2012, together with the Company's previously communicated second quarter 20 II balance sheet restructure.

Net Interest Income Increases

Net interest income of$16.1 million for the first quarter of 20 12 increased by $546,000, or 3.5%, from the fourth quarter of2011 and by $2.7 million, or 20.4%, from the comparable 2011 period. This increase is due to the continued reduction in the cost of funds and the second quarter 2011 balance sheet restructure. Federal Home Loan Bank of Boston advances totaled $125.9 million at March 31, 2012 at a weighted average cost of 1.79% as compared to $251.4 million at March 31, 2011 at a weighted average cost of 3.82%. The tax equivalent net interest margin for the first quarter of2012 was 3.83%, compared to 3.77% for the fourth quarter of 20 11 and 3.10% for the comparable period in 2011.

The Company's tax equivalent yield on interest earning assets decreased 6 basis points during the quarter ending March 31, 2012 to 4.49% from 4.55% during the fourth quarter 2011, and increased by 15 basis points from 4.34% during first quarter of 2011. The decrease in the average yield during the first quarter was attributable to the strong production growth of new loans at lower yields than the fourth quarter last year and adjustable rate loans repricing downward. The increase in the average yield compared to the first quarter of2011 was attributable to the reinvestment ofthe cash received in the second-step conversion from low-yielding short-term investments into higher-yielding loan and investment portfolios.

The cost of interest bearing deposits decreased 13 basis points to 0.79% in the first quarter of2012 from 0.92% in the fourth quarter of2011, and decreased by 30 basis points from 1.09% in the comparable 2011 period reflective of the Company's continued focus on growing low-cost core deposits and decreasing the cost of funds. The cost of interest bearing liabilities decreased 16 basis points to 0.91% in the first quarter of 2012 from 1.07% in the fourth quarter of 2011, and decreased by 71 basis points from 1.62% during the first quarter of 2011.

Provision For Loan Losses Declines

Net charge-offs for the first quarter were $202,000 , or 0.01% of average loans outstanding, an increase from $38,000, or 0.00% of average loans outstanding, in the prior year period. Provision expense continues to be assessed in correlation with the Company 's loan growth and risk management enhancements.

Non-Interest Income

Non-interest income totaled $2.7 million for the first quarter 2012, down $370,000, or 12.2%, on a linked quarter basis and up $982,000, or 58.2%, from the first quarter 2011. The change in non-interest income is primarily attributable to the varying levels of net gains from sales ofloans which totaled $525,000 for the first quarter 2012, down $726,000, or 58.0%, on a linked quarter basis and up $466,000, or 789.8%, from the first quarter 2011. The Company sold residential mortgages totaling $17.5 million in the first quarter 2012, $37.0 million in the fourth quarter 2011 and $5.0 million in the first quarter 2011.

Service charges and fee income totaled $1.8 million for the first quarter 2012, an increase of$261 ,000, or 16.7%, on a linked quarter basis and an increase of $230,000, or 14.4%, from the same period in the prior year. Included in the comparison to both periods is the recovery of$105,000 in the first quarter of 2012 from a business interruption insurance policy related to the temporary closure of one of the Company's branch offices due to storm related damage in 2011. Additionally, included in the first quarter of 20 12 was the recapture ofa prior period recognition of a mortgage servicing asset valuation writedown of $108,000. Increases in ATM fee income were offset by lower loan fee income generated by Rockville Bank Mortgage, Inc. ("RBMI"). The Company announced in the fourth quarter of 2011 that the assets of the Bank's subsidiary, RBMI (operating under the trade name Family Choice Mortgage) would be transferred to the Bank in the first quarter of2012.

Non-Interest Expense

Non-interest expense totaled $12.3 million for the first quarter of2012, up $575,000, or 4.9%, on a linked quarter basis and down $3.6 million , or 22.6%, from the first quarter 2011. The operating results for the first quarter of 2011 included a $5.0 million expense for the cash contribution to the Foundation; excluding the Foundation contribution, noninterest expense increased year-over-year by $1.4 million, or 13.2%. The increase in noninterest expenses primarily reflects the increases in salaries and employee benefits costs related to the increased staffing in the risk management, information technology, finance, branch administration and commercial banking areas, significantly in 2011 and continued to a lesser extent in 2012, as the Company prepared to prudently leverage capital and accelerate growth. Full-time equivalent employees increased to 280 at March 31,2012 from 242 at March 31, 2011. Salaries and employee benefits costs increased $1.2 million, or 20.0%, on a linked quarter basis and $1.5 million, or 25.6%, compared to the first quarter of 20 II. The linked quarter additionally reflects the impact of an accrual adjustment in the fourth quarter of 20 II of approximately $300,000 in an employee incentive program.

On a linked quarter basis the increase in salaries and benefits expense was partially offset by a $90,000, or 44.1%, decrease in marketing expense and a $320,000 , or 53.2%, decrease in OREO expense. On a year-aver-year basis, this expense was partially offset by a $210,000, or 64.8%, decrease in marketing expense and a $209,000, or 40.7%, decrease in FDIC expense.
