Analysts:.
Good morning and welcome to the Erie Indemnity Company First Quarter 2016 Earnings Conference Call. I would like to introduce your host for today's call, Mr. Scott Beilharz, Vice President of Investor Relations. Sir, you may begin..
Thank you, [Sahid], and welcome everyone. We appreciate you joining us for today's discussion about the 2016 first quarter results. Joining me today are Terry Cavanaugh, President and Chief Executive Officer; Greg Gutting, Interim Executive Vice President and Chief Financial Officer; and Sean McLaughlin, Executive Vice President and General Counsel.
Our earnings release and financial supplement were issued yesterday afternoon after the market closed and are available within the Investor Relations section of our website, erieinsurance.com. We will start the call today with opening remarks from Terry and Greg and then we will open the call for your questions.

LuAnn Datesh, Vice President, CNX Gas Corporation, and retired Erie Executive George Lucore. LuAnn and George bring a wealth of knowledge and experience and will be true assets to our board. I will now ask Greg Gutting to provide the detail of our financial results for the quarter. .
Thank you, Terry. As Terry mentioned, our first quarter results continued to build on the success we had in 2015. Net income was $0.87 per diluted share compared to $0.74 in the first quarter of last year. This growth was driven by increased revenue from operations and lower expense growth. Revenue from operations grew by $24 million.
This meaningful top line growth represents a 6.8% increase over the prior year period and it's consistent with the 7.1% increase in the direct and assumed premiums written by the exchange. For the quarter, cost of operations grew $8.7 million or 2.9% to $307 million.
Commission expense grew $15 million or 7.7%, primarily driven by the direct and assumed written premiums of the exchange and higher agent incentive costs related to profitable growth. Non-commission expenses decreased $6.3 million in the first quarter of 2016 compared to the first quarter of 2015.
For the quarter information technology costs decreased $4.7 million due to decreased professional fees. Administrate and other costs decreased $2.6 million due to a decrease in personnel costs. For the quarter, net revenue from operations before taxes totaled $68 million, up $15 million over the prior year quarter.
Revenue growth outpaced expense growth, increasing our gross margin to 18.1% compared to 14.9% in the first quarter of 2015. Indemnity’s investment income for the quarter was down $4 million compared to the same period in 2015. Of that $4 million decrease, $3 million represents a decrease in our limited partnership investment return.
As a reminder, this portion of our portfolio is in run-off and continues to produce variable return. Finally, in the first three months of 2016 we are pleased to have paid $34 million in dividends to our shareholders. I'll now turn the call back over to Terry. .
Thank you, Greg. I think we’d like to now open up the call to any questions anybody might have..
