Thanks, Chris, and good morning, everyone. First I want to highlight our core result shown on Slide 3. Our diluted core earnings per share were $0.49 and core net income of $12.9 million, which compares to pro forma core net income of $10.3 million last quarter. Our core return on average assets rose to 1.61%, and our core return on average tangible common equity was 13%.
On Slide 4, which shows our pro forma, GAAP reported return on average assets increased 48 basis points since 2013 to 1.32% for the first half of 2017. This graph demonstrates the strong and consistent growth in our profitability that we have achieved over the last 4 years and that we continue to deliver this quarter with the 1.40% core return on average assets, this was up 9 basis points on a linked-quarter basis. The bottom half of Slide 4 shows the key drivers to our profitability. The first graph shows our loan-to-deposit ratio, which has continued to shift with a higher percentage of loan set for sale at 16% and our loan sale for investment at 72% as we have steadily leveraged our core deposit franchise.
Our net interest margin continues to be at or above our long-term targets and we continue to work through the challenging interest rate environment. Noninterest income increased 14.7% from the previous quarter, driven by expected seasonal growth in Mortgage Banking income. And finally, our nonperforming assets to total assets was down 20 basis points to 58 basis points from the second quarter last year.
Next, and looking at Slide 5 at the outline of our historical yields and cost, as detailed previously, we had another healthy period for NIM, which was 4.19% in the second quarter. Adjusting for 11 basis points in accretion benefit, our core net interest margin was 4.08%, slightly above our long-term targeted range of 3.85% to 4.05%. Our total loan yield was down 25 basis points from the first quarter due to a 3 basis point decline in the contractual rate of loans, 8 basis points on loan fee, 7 basis points of accretion on purchased loans and 6 basis points from syndication fees. Our cost-to-deposits remained -- remains a strength for the company, increasing only 2 basis points in the quarter to 34 basis points, implying a minimal deposit beta at this point. Giving our -- given our 26% noninterest-bearing deposit composition, we expect deposit betas to continue to remain low while we're expecting slight upward pressure as the market continues to adjust to the upward movements at the short end of the curve, given recent Federal Reserve rate hikes.
As a team, we remain very focused on our funding structure and view that as a strength. On an overall basis, our loan deals haven't moved with -- move or benefited from the overall rate increases, due primarily to working through floors and the long-term yield curve. However, we expect to benefit in the coming quarters based on the full repricing of the portfolio, with approximately 49% of our loan portfolio now having variable rates.
Overall, our balance sheet is positioned to benefit from the current rate environment from a strong deposit base and mix of earning assets.
Next, on Slide 6, shows that our loans were up 12.6% to $1.97 billion at the end of the second quarter compared with last year, and we're up 3.7% or 14.8% annualized on a linked-quarter basis. Average loans rose 15.6% on an annualized basis from the first quarter reflecting the increased loan demand we enjoyed from our metropolitan and community markets. The chart at the top right of this page reflects our construction and CRE concentration levels of 86% and 184% of capital respectively, well below the regulatory guidelines, leaving room for growth as needed.
On Slide 7, which demonstrates that our total deposit were up 8.5% to $2.7 billion since the second quarter of last year. This growth was due in part to noninterest-bearing deposits that were up 5.2% to $715 million from the second quarter of last year. At the end of the second quarter, noninterest-bearing deposits were 26.2% of total deposits. Our cost of deposits has remained relatively stable over the past year around 30 basis points and was up 6 basis points since the second quarter of last year. Including the noninterest-bearing deposits at the end of the second quarter, we're at approximately $50 million in mortgage servicing escrow deposits, up from $44 million at the end of the first quarter.
Now turning to Slide 8, illustrating our Mortgage Banking revenues and activities for the quarter. As Chris noted in his opening comments, we had excellent -- we had an excellent quarter from our Mortgage Banking operations and Mortgage Banking income rose 20.6% to $30.2 million in the second quarter of 2017 on a linked-quarter basis and was roughly flat on a year-over-year basis. In the second quarter, our interest rate locked pipeline volume rose 35% to $2.16 billion from the first quarter, and a -- and our locked pipeline was up 22% to $547 million at the end of the quarter. This quarter's growth benefited from increased volumes across all major channels, including increased purchase volumes and from the continued expansion of our correspondent channel, offsetting declines from the Consumer Direct channel. As a percent of total volume, our purchase volume rose to 64% in the second quarter compared with 60% in the first quarter of 2017 and 42% in the second quarter of last year.
One item that I want to clarify on our Mortgage Banking income, is the net fair value adjustment, which is primarily related to our interest rate locked commitment generation, the first step in our revenue generation activities within our mortgage operations. This ultimately turns into the gain on the sale of the loans in future periods, as the loans were closed and sold into the secondary market.
As we reported last quarter, we elected the fair value treatment for mortgage servicing rights and this resulted in a $1.8 billion valuation decrease in the second quarter of 2017. We have now implemented various hedging strategies on an MSR portfolio which we believe will mitigate those fair value fluctuations in future periods.
Our outlook for mortgage volumes for the second half of 2017 is to remain steady in the third quarter and seasonally decline into and throughout the fourth quarter. We reiterate our prior guidance for 2017 volumes to increase over 2016 on a full year basis, resulting in a bottom line contribution for the full year 2017 that is relatively flat versus 2016. Currently, we are on track on both of these targets for the first half of 2017 as we previously outlined.
Next, on Slide 9, which outlines our overall operating leverage and efficiency, which continues to be a focus of improving on our operating leverage and efficiency as we move forward. As Chris mentioned, our efficiency ratio was in the low to mid-60s for our Banking segment during most of last year and improved to 60.4% in the second quarter, which we view as a positive in moving forward on our long-term target levels.
Our Mortgage segment has improved over the past 3 quarters and was 78.3% in the second quarter of 2017. We expect our operating efficiency to improve as we move forward, based on the economy to scale we expect to achieve with the Clayton acquisition as well as investments we made in upgraded systems and growth from our legacy markets. We believe we have existing capacity to grow our business in our metropolitan markets, creating additional operating leverage.
Our excellent loan growth this quarter highlights our opportunities to leverage our existing banking infrastructure as we move forward in future periods. We also expect to gain further efficiency in this business as we continue to fine-tune their operations going forward.
Also, our effective tax rate was 36.9% for the second quarter and was in line with our previously forecast of approximately 37% for the remainder of 2017.
Next, on Slide 10, our asset quality remains strong and showed improvement from last year based on lower nonperforming assets to assets, a consistent decline in classified loans and our net recovery position in the second quarter. Since the second quarter of 2016, our nonperforming assets are down 20 basis points to 58 basis points at the end of the second quarter 2017. Classified loans are down $6 million, a decrease of over 6% to $36 million during the same time period. Our loan loss reserve to loan sale per investment was 1.18% at June 30, 2017, and our net charge-offs to average loans were in net recovery position or the second quarter in a row. We continue to expect recovery opportunities to moderate but view trend as a testament to our overall team on the collection of previously charged-off loans.
Going forward, we expect our loan loss reserve to loans to stay around 1.2%, excluding the impact of the Clayton Banks acquisition.
Next, on Slide 11, as Chris highlighted in his comments, we completed a common stock offering of approximately 4.8 million shares during the quarter, raising about $152.7 million in new capital. I also wanted to outline our projections for average diluted and period-end share accounts over the next couple of quarters, given the moving pieces and timing of the Clayton Bank acquisition.
In the second quarter we had period-end shares of $28.968 million and weighted average today shares of $26.301 million. Upon issuing Clayton Holding company 1.521 million shares at closing, we expect to end the third quarter with approximately 30.6 million shares outstanding and have weighted average shares of 30.5 million diluted shares for the quarter -- for the third quarter. Similarly, for the fourth quarter, we expect to end the quarter and the year with approximately 30.5 million shares outstanding and have a weighted average shares for the fourth quarter of approximately 31.1 million. The table on the left-hand side shows the positive effect that additional capital had on our key capital ratios. Shareholders' equity to assets rose 44 basis points to 15.2%. With all of our Tier 1 related ratios, we're up 500 basis points compared with the first quarter due to the capital raise. All of these key measures were well above the amounts required for the regulatory agencies to be a well-capitalized institution of the highest rating.
With that overview, I want to turn the call back over to Chris for closing comments, and then we'll open the call for your questions.
