Thank you, John. For the fourth quarter of 2011, we reported net income of $12.1 million or $0.29 per diluted share compared to net income of $11.6 million or $0.28 cents per diluted share reported last quarter. As John mentioned, we benefited from a significant reduction in our allowance for loan and lease losses, resulting in a credit supervision for loan and lease losses of $11.2 million.
As we have seen throughout 2011, the reduction in our allowance is primarily due to improvements in our credit risk profile, as our loan portfolio continues to show signs of stabilization. During the quarter, non-performing assets were reduced by $27.7 million to $195.6 million in December 31st, 2011.
Nonperforming assets were $223.3 million at September 30th, 2011. Our ALLL as a percentage of total loans, decreased from 7.0% at September 30th, 2011 to 5.9% at December 31st, 2011. Similarly, the ratio of our ALLL to nonperforming assets decreased slightly from 64% in September 30th, 62% at December 31st, 2011. Bill will provide more details about our credit position later in this call.
Net interest income for the quarter was $30.8 million compared to $29.8 million in the previous quarter. Our net interest margin was 3.25% and 3.05% for the same respective quarters. We are seeing gradual improvement in both our net interest income and net interest margin as we continue to deploy -- to redeploy our excess liquidity into higher-yielding assets and reduce our overall funding cost. The reduction in our funding cost was largely due to the previously reported prepayment of $121 million in long-term borrowings at the Federal Home Loan Bank of Seattle in the third quarter.
Those borrowings carried a weighted average interest rate of 4.36%. During the quarter, we increased our investment securities portfolio by $26 million to approximately $1.5 billion. We continue to use an investment strategy which concentrates on the purchases of agency debentures and MBS securities with relatively short duration.
Non-interest income for the quarter totaled $15.2 million up from $11.5 million in the previous quarter. The sequential quarter increase was primarily due to higher gains on sales of residential mortgage loans of $2.5 million and the recognition of a $1 million gain on the sale of investment securities.
This was partially offset by lower unrealized gains and outstanding interest rate locks of $1.1 million. Non-interest expense for the quarter totaled $45.2 million down from $48.8 million at previous quarter.
The sequential quarter decrease was primarily attributable to the recognition of a $6.2 million prepayment penalty related to the previously mentioned pay down of Federal Home Loan bank borrowings in the third quarter. A lower accrual for our contribution to the Central Pacific Bank Foundation of $1.5 million and a settlement of a class action lawsuit related to our previous policies for assessing overdraft fees totaling $1.2 million, also in the third quarter.
Partially offsetting these items were increased net credit related charges, which includes changes in the reserve for unfunded commitment, foreclosed asset expense, and a write down of loans held for sale of $4.6 million, and higher salaries and employee benefits of $1.5 million in the fourth quarter.
Our adjusted efficiency ratio for the quarter, which excludes foreclosed asset expense and write downs of loans held for sale was 92% compared to 99.1% in the previous quarter. Because we continued to have a full valuation allowance established against our net deferred tax assets, we did not recognize any income tax expense for the quarter.
At December 31, 2011, our Tier 1 risk-based capital -- total risk-based capital and leverage capital ratios all improved to 22.94%, 24.24% and 13.8% respectively. This compares to 22.63%, 23.94% and 13.19% respectively at September 30th, 2011.
Our capital ratios continue to be well in excess of the minimum levels required by both the memorandum of understanding, that we entered into with our regulators and the levels required for a well-capitalized regulatory designations.
This completes our financial summary. I’d like now to turn the call over to Bill who will provide additional background related to our credit risk position.
