Thank you, operator, and thank you, everyone, for joining us this morning. What a crazy year this has been, and there's still 5 months to go before the end of the year. On the call with me today are our President, Stu Lubow; Chief Financial Officer, Avi Reddy; and our Chief Accounting Officer, Leslie Veluswamy. In my prepared remarks, I'll make some enterprise-wide comments, and then we'll pick up some of the broad themes that continue to underline the earnings release this quarter.
As you've seen, we had a very strong quarter end of June with core EPS of $0.39. This was inclusive of the impact of a $6.1 million addition to the general allowance for loan losses, which we determined to be prudent, given the potential impact of the pandemic. Our strong core EPS was aided by net interest margin expansion, fee income growth and expense control. For those that have followed our story over the past few years, in order to diversify our assets and our revenue stream, we began the transition toward a commercial bank model in early 2017.
The positive impact of that transformation is taking hold now as most apparent beginning with this quarter's results. It also answers the question we got asked 3.5 years ago, how long is this transition going to take? I suppose at this point, we can say -- easily say that it's going to take 3 years. So we just passed the 3-year mark. And we knew a year ago that these quarters were coming, and I'm glad to see that we finally got here. On a linked-quarter basis, NPLs were going down -- went down this quarter, approximately 15% to $15.3 million, that’s $15 million on a $5.5 billion portfolio. Our loan deferrals were also down to approximately $916 million at June 30 compared to the peak, which was reached in the month of May of approximately $1.1 billion.
More encouragingly, of the first tranche of $489 million of loans that was provided forbearance in the month of April, $195 million, or 40% [ has resumed ] full payment and $120 million or approximately 25% is now paying full interest and escrow where required. Together, that adds up to approximately 65% of the April tranche deferrals. Of the remaining loans in the April tranche of $169 million is paying at least full escrow. So the migration of the deferred portfolio to full performing status is well underway.
In the years between 2007 and 2013, Dime's cumulative net charge-offs were only 130 basis points of beginning loan balances at the start of the crisis. That's cumulative net charge-offs over a period of 6 years since the beginning of the crisis at that time. That number was approximately 5x lower than the overall bank index. Given the low LTV nature of the multifamily portfolio, which was 50% at June 30, we anticipate our track record to continue.
Due to the city's limited geography, multifamily apartment buildings are the primary form of housing in New York City. Many of our borrowers have remained with Dime through intergenerational family ownership across various difficult economic cycles. I'm confident that these owners will continue to manage their properties well through this pandemic. New York City housing has been through many cycles. And while COVID is a unique situation in the past decade, New York City has seen significant investment in the TAMI sector, technology, advertising, media, and information companies. We here at Dime are believers in the long-term demand for housing stock in New York City, and especially given the low LTVs of the loans in our portfolio, we remain optimistic that our credit performance will once again outperform over time.
Right now, we are committed to helping our borrowers get through the current environment while improving their payment profile, which we have demonstrated in this quarter's release. As you might expect, we are monitoring all areas of our portfolio proactively, including our exposure to hotels, in which we had about $173 million investment, in restaurants of about $27 million. We have Stu Lubow here, who will answer any of your questions in a more granular way during the Q&A section of the presentation this morning. We have also built a balance sheet with significant capital strength.
In the second quarter, we opportunistically raised $44 million of net proceeds from the issuance of perpetual preferred stock sourced from many of the same investors who are familiar with our story from our earlier preferred issuance in February. This has resulted in capital ratios moving to the top end of our peer group. Our leverage ratio is in excess of 10%. Our Tier 1 risk-based ratio is in excess of 13%, and our total capital ratio is in excess of 16%. Our capital base, coupled with the low LTV and improved core profitability will certainly serve us well in the current environment.
Next, I'd like to touch briefly upon Dime's involvement in the Paycheck Protection Program. In the 3 years ago when we started, we did not even have an SBA program here at Dime. So we've made great progress shown by the results here. In the second quarter, we originated $319 million of PPP loans. And as of June 30, our PPP related deposit balances were approximately $104 million. Potential unrecognized income from processing these loans is currently $8.9 million. Many of these customers are new relationships to Dime, and many of these new clients will remember that we were a source of help to them in their time of need.
As I've mentioned in the past, Dime's strategic plan is built upon improving 5 fundamental metrics: one, growing our total checking account balances; two, increasing low-cost business deposits; number three, growing our relationship-based commercial loans; four, growing sources of and the contribution of nonspread revenue, and five, maintaining appropriate liquidity, reducing our CRE concentration ratio and operating with strong capital ratios. Now a quick update on each of those, starting first with the growth in checking account balances. On a year-over-year basis, average noninterest-bearing and interest-bearing checking accounts increased by 54% to $841 million.
The second metric is that of increasing low-cost business deposits. Total commercial bank deposits from our business banking division, plus our legacy multifamily division increased by almost 37% on a year-over-year basis to $675 million. The second financial objective is growing relationship-based commercial loans. The Business Banking division portfolio is currently approximately $1.6 billion, excluding the PPP loans. This business continues to be accretive to our overall NIM and has contributed to 7 consecutive quarters of core NIM expansion. Our fourth targeted metric is non-spread revenue. Non-spread revenue at Dime, excluding security gains and losses, grew by approximately 83% on a year-over-year basis. This was mainly driven by an increase in customer-related swap fee income. And lastly, we are operating with a very strong capital ratios, as I pointed out earlier. We have reduced our CRE concentration ratio to 545%. And just a reminder, again, that Dime was well over 900% only a few years ago.
In summary, we continue to make quantifiable progress on all 5 strategic objectives. The most satisfying aspect of the transformation for me is the progress that's been made on the deposit side of the balance sheet, with noninterest-bearing deposits now comprising 15% of our deposit base. And believe me, when I think back to the years when we were at 6%, 15% seemed like a pipe dream, but we still have a ways to go, and it's still not best-in-class yet, which is our goal. Deposits to loans for Business Banking division are running at 26% of the loan portfolio compared to approximately 6% for the legacy multifamily business. Improving the quality of our deposit base was the most important guiding tenet of our business model transformation.
Finally, a last word on our announced merger with Bridge Bancorp. Hopefully, we've already listened to our merger call at the end -- excuse me, at the start of the month, which detailed the strategic rationale. We have had follow-up conversations with many of our shareholders and analysts since that time. In just 4 weeks, we have made important progress in our integration efforts, and our teams are extremely -- working extremely cohesively together. It will be a busy 5 months ahead. We are aiming to close the merger in early January, and I'm extremely excited for the opportunity that lies ahead for our combined franchise. As Bridge also noted in their earnings release, this was a unique opportunity for both companies. Together, we are very determined to create the next great New York Community banking franchise.
At this point, I'd like to turn the conference call over to our Chief Financial Officer, Avi Reddy, who will provide some additional color on our first quarter results.
