(NASDAQ: BOFI) (“BofI”), parent of Bank of Internet USA (the “Bank”), today announced unaudited financial results for its fourth quarter and year ended June 30, 2011. Net income for the fourth quarter ending June 30, 2011 was $5,545,000, up 18.1% over the $4,697,000 earned for the fourth quarter ended June 30, 2010.

Diluted earnings per share were up 13.6% to $0.50 per diluted share for fourth quarter of fiscal 2011 compared to $0.44 per diluted share for the fourth quarter of fiscal 2010.

BofI achieved new record levels of loan originations as the loan portfolio reached $1,325.1 million at June 30, 2011, up 71.0% from the $774.9 million loan portfolio at June 30, 2010 and up 19.0% from the $1,113.8 million loan portfolio at March 31, 2011. Portfolio loan originations and purchases totaled $261.6 million for the fourth quarter of fiscal 2011 up $198.9 million from the originations and purchases in the fourth quarter of fiscal 2010. The growth in the loan portfolio produced a fourth quarter net interest income increase of $3.9 million year over year. In addition, BofI’s mortgage banking operations originated $53.9 million in loans in fourth quarter of fiscal 2011, up 106.8% compared to the fourth quarter of fiscal 2010.

Excluding the after-tax impact of net gains related to investment securities, core earnings for the 2011 fiscal year and for the fourth quarter ended June 30, 2011 increased $2.0 million and $0.8 million, respectively, compared to fiscal 2010 periods. Net income for the year ended June 30, 2011 was $20,579,000 compared to $21,128,000 for fiscal 2010. Earnings attributable to BofI’s common stockholders were $20,270,000 or $1.87 per diluted share this fiscal year compared to $20,517,000 or $2.22 per diluted share last fiscal year.

“I would like to congratulate our residential lending and our income property lending groups for a fantastic finish in a record year of loan growth,” said Greg Garrabrants, President and Chief Executive Officer. “Our multifamily and single family portfolio businesses combined to originate $247.8 million, up 62.7% from the $152.3 million originated last quarter and up 653.2% over the $32.9 million originated in the quarter ended June 30, 2010. This year, once again, our bank reached its goal to achieve a return on average common equity in excess of 15%. The Bank has exceeded its 15% ROE target in the last two years while growing its assets at a combined average annual rate of 22.1% with no adverse impact on its strong asset quality or net interest margin. The Bank’s non-performing assets as a percent of total assets was 0.99% at June 30, 2011, slightly improved over the 1.01% at June 30, 2010. The Bank’s net interest margin for the fourth quarter this year was 3.69%, slightly improved over the 3.63% for the fourth quarter last year.”

“We were pleased that, as a result of this performance, we were recently recognized as the 2^nd highest performing thrift in SNL Financial’s ranking of the 100 largest publically traded thrifts for the most recent 12-month period ending March 31, 2011. Over the last several years, the Bank has consistently been rated one of the top five performing thrifts in the nation based upon return on average assets; return on average equity; three-year compound annual growth rate in tangible book value per share; efficiency ratio; non-performing loans and net charge-offs. What the rankings cannot fully capture is the extent to which the Bank is bearing current operating cost for new business lines that will not contribute to earnings until 2012. These new businesses are important for the Bank to sustain its strong performance, realize the operating leverage inherent in the business model, and add to the franchise value of the Bank. We will discuss these new business investments in greater detail on this quarter’s earnings call.”

Quarter Earnings Summary

During the quarter ended June 30, 2011, BofI earned $5,545,000 compared to $4,697,000 for the three months ended June 30, 2010. Net interest income grew 31.6% in 2011 compared to 2010 primarily due to a 29.6% increase in average interest earning assets resulting from loan growth. Loan loss provisions were $1,450,000 for the quarter ended June 30, 2011 compared to $925,000 for the quarter ended June 30, 2010. The increase in loan loss provisions reflects an increase in RV write-offs during the fourth quarter this year compared to the fourth quarter last year.

Non-interest income increased $1,121,000 in the fourth quarter of fiscal 2011 compared to the fourth quarter of 2010, primarily due to increased mortgage banking revenue.

Non-interest expense, or operating costs, increased $2,857,000, mainly as a result of an increase in compensation expense of $1,957,000 related to additional staffing added during the year. The Bank’s staff increased from 90 to 173 full-time equivalent employees between June 30, 2010 and 2011. Professional services, which include accounting and legal fees, increased $261,000 for the quarter ended June 30, 2011, compared to the quarter ended June 30, 2010. The increase in professional services was primarily due to legal fees for loan acquisition contracts and foreclosed assets. Advertising and promotional expense increased $283,000 for the three-month ended June 30, 2011 compared to June 30, 2010 due to increases in lead acquisitions for our single family loan origination programs and increased advertising for our multifamily origination program. An increase in regulatory fees of $202,000 was related to the growth in deposits, an increase of $189,000 in depreciation and amortization was due to the upgrade and replacement of computer systems, an increase in other general and administrative costs of $154,000 was due to increased costs associated with loan operations as well as telephone, supplies and other costs which were all partially offset by a decrease in expense related to management of real estate owned and repossessed vehicles of $334,000.

Balance Sheet Summary

Total assets increased by $519,006,000, or 36.5%, to $1,940,087,000 at June 30, 2011 from $1,421,081,000 at June 30, 2010. The loan portfolio increased a net $550,202,000 primarily from loan originations and pool purchases of $733,685,000 less repayments of $163,348,000. Investment securities decreased by $46,289,000 primarily due to $323,636,000 in maturities, calls and principal repayments, and $16,523,000 in sales, partially offset by $284,034,000 in purchases. Total liabilities increased by $501,048,000, or 38.8%, to $1,792,321,000 at June 30, 2011 from $1,291,273,000 at June 30, 2010. The increase in total liabilities resulted primarily from growth in time deposits of $447,295,000 and increased borrowings of $124,501,000 partially offset by a reduction in savings account balances of $89,909,000. Stockholders’ equity increased by $17,958,000, or 13.8%, to $147,766,000 at June 30, 2011 from $129,808,000 at June 30, 2010. The increase was primarily the result of $20,579,000 in net income, and stock compensation items of $2,702,000, partially offset by a net comprehensive loss of $5,014,000.
