With that, I'll turn the call over to Jack.

Thank you, Peter, and good afternoon, everyone. We appreciate you joining us today. On Slide 2, we provide an overview of our second quarter results. For the quarter, operating earnings were $67.2 million or $0.20 per share, up from $60.6 million or $0.18 per share in the first quarter. Net income after -- net income for the quarter, including non-operating items, was $64.8 million or $0.19 per share. The net interest margin declined to 3.97% compared to the 4.01% in the first quarter. The decline in the margin is the result of lower loan yields and higher levels of securities purchased earlier in the quarter in anticipation of our receipt of the proceeds for the Citizens branch transaction late in the quarter. This is partially offset by cost recovery income related to negotiated settlements and payoffs in the acquired loan portfolio.
Loan growth, including runoff in the acquired portfolios, amounted to 2.3% on an annualized basis, which was entirely funded by deposit growth.
Originated loan growth was strong and amounted to 11.2% on an annualized basis. Noninterest income increased $3.3 million compared to the first quarter, reaching $75.7 million. This increase was primarily due to growth in cash management fees, operating lease income, prepayment fees and gain on sale of acquired loans.
The efficiency ratio improved to 61.5% from 63.2% in the first quarter. This is a result of improved operating leverage from higher revenues and lower expenses. Capital ratios remained strong with the tangible equity ratio at 11.5% for the second quarter. We continue to make progress deploying our capital through balance sheet growth and share repurchase activity.
On Slide 3, we discussed several recent initiatives. Most importantly, we continue to expand our presence in key growth markets such as the New York metro area. We recently completed the acquisition of 57 Citizens branches in the greater New York metro area and rebranded all of the acquired branches over the weekend of June 22. 53 of the branches are in Stop & Shop supermarkets and 4 are traditional branches.
