Net Interest Income
Net interest income was $10.5 million, or 4.04% of average interest earning assets ("net interest margin"), for the third quarter of 2013 compared with $10.6 million, or a 4.36% net interest margin, for the same period a year earlier. For the first nine months of 2013, net interest income was $30.8 million, or a 4.07% net interest margin, compared with $31.7 million, or a 4.49% net interest margin for the same period a year ago. The decline in net interest income is largely the result of the decline in yields on our loan and investment portfolios due to the historically low interest rate environment resulting from the slowdown in the economy, despite strong year-over-year growth in the Company's loan portfolio.
Provision for Loan Losses
No provisions for loan losses were recorded for the third quarter or the first nine months of 2013 compared with $1.3 million and $7.7 million recorded in the same respective periods a year earlier. The lack of provisions for loan losses during the three and nine months ended September 30, 2013, was largely driven by continued improvements in the overall credit quality of the loan portfolio, continued improvement in our historical loan loss experience and a shift in the loan portfolio to products with lower credit risks, which favorable trends more than offset the impacts of the growth in the overall loan balance. Net charge-offs declined $1.0 million, or 67.8%, to $0.5 million for the third quarter of 2013 compared with net charge-offs of $1.5 million for the same period a year earlier. For the first nine months of 2013, net charge-offs declined $8.3 million, or 92.2%, to $0.7 million compared with $9.0 million for the same period in 2012. Annualized net loan charge-offs to total gross loans for the third quarter of 2013 declined 61 basis points to 0.24% compared with 0.85% for the third quarter of 2012. For the first nine months of 2013, annualized net loan charge-offs to total gross loans declined 169 basis points to 0.12% compared with 1.81% for the same period a year earlier.
