Thank you, Janelle. For the first quarter of 2014, AMERISAFE reported net income of $10.5 million or $0.56 per diluted share compared to $8.9 million or $0.47 per diluted share in the first quarter of 2013.
As Janelle mentioned, gross premiums written rose 6.6% from the year-ago quarter, while net premiums written declined 8.2%. The difference in the increase between gross and net reflects the impact of our new 2014 reinsurance treaty, as we retained an additional $1 million on the first layer and, thus, seed less premium to the reinsurers. Net premiums earned increased to 11.2% from the year-ago quarter and were also favorably impacted by the reinsurance treaty.
Our net investment income totaled $6.7 million in the first quarter of 2014, basically flat with last year's first quarter. The tax equivalent yield on our investment portfolio was 3.8% in the first quarter of 2014, down 40 basis points from the first quarter of 2013. Our portfolio continues to carry a AA- rating with an average duration of approximately 3.9 years and remains quite liquid with roughly 20% rolling off over the next 15 months.
In total, the revenue for the first quarter of 2014 was $96.2 million, up 11.1% from the year-ago period. Turning to the expenses. Our current accident year loss ratio for the quarter was 71.5% compared to the 73.2% a year ago. Our incurred loss and loss adjustment expenses totaled $61.3 million for the quarter, which included $2.5 million of favorable prior year development. This compares to loss and loss adjustment expenses of $56 million in last year's first quarter, which included $2.4 million of favorable prior year development.
In total, our net calendar year loss ratio for the first quarter of 2014 was 68.7% compared to 70.3% 1 year ago.
With regard to operating expenses. Total underwriting and other expenses increased 13.2% to $21.4 million compared to $18.9 million in the first quarter of 2013. The increase in expenses reflects a few specific items for the quarter, in particular: a $400,000 under-accrual of 2013 bonus compensation; the timing of other expenses related to meetings, licensing and fees of approximately $365,000; and most impactful of all, a change in our reinsurance treaty, which resulted in approximately $1.7 million of lower seeding commissions and lower accruals for contingent profit commission than we had in the first quarter of 2013.
By category, the 2014 first quarter expense components include $6.7 million of salaries and benefits, $6.7 million of commissions and $8 million of underwriting and other costs. The expense ratio increased 20 basis points to 23.9% from 23.7% in the same quarter a year ago. In total, our combined ratio was 92.7% for the first quarter versus 94.7% for the same period in 2013. Return on average equity for the first quarter of 2014 was 10.1% compared to 9.2% for the first quarter of 2013. Book value per share at March 31, 2014, was $22.54, an increase of 6.3% from March 31, 2013, and modestly ahead of our year-end number of $22.41. Importantly, in addition to our regular dividend of $0.12 per share, we also paid an extraordinary dividend of $0.50 per share in the first quarter. Combined, these dividend payments totaled $11.5 million and are a reflection of the board and management's proactive approach to returning capital to stakeholders, as well as the favorable outlook for the company.
Cash flows from operations remained strong during the first quarter of 2014 at $30.3 million compared to $21.8 million in 2013's first quarter.
And finally, our statutory surplus grew to $364 million at quarter end.
Those concluded my prepared remarks on the financials. I will now turn the discussion back to Allen. Allen?
