Analyst · this time, I would like to turn the call over to Rick Wayne. Please go ahead, sir
Thank you. Good morning, and thank all of you for joining us today. With me on this call are JP Lapointe, our Chief Financial Officer; and Pat Dignan, our Chief Credit Officer and Executive Vice President. After my comments, JP, Pat and I will be happy to answer your questions.
Last night, we uploaded an investor tech. And this morning, I'm not going to go through page-by-page on the assumption that we provided the information, and I'm sure those on the call have read it, but I do want to amplify a few points -- well, more than a few. First, let me just say, we know it was a great quarter in almost every aspect. And I will, in my following comments, explain why we think that is true.
First, just some earnings and key ratio highlights. We had net income of $11.4 million, which compared to $9.9 million in the linked quarter, up 15%. Earnings per share were $1.42 diluted. Return on equity was 18.8%. Return on assets was 2.9%. NIM was 5.24%. And if we exclude PPP from the NIM calculation, the NIM would have been 6.44%. Obviously, those are really outstanding numbers.
Let me first start with a discussion of the loan activity. To state the obvious, if you increase your loan balance and maintain high rates, we're going to have an increase in net interest income, which is what occurred. We had a record $261 million of purchases and originations, and that's a record by a lot. The originations were $168.4 million, and the purchase loans were $92.1 million. Also, our rates in our portfolio remained high at 8.96% on our purchase portfolio and $6.48 on our originated portfolio. And I'll remind you that most of our originated portfolio, well, virtually all of it, is tied to prime and floats. And so as rates go up, as they will, we're going to be picking up additional interest income from that portfolio.
Just to put this in context, our loan portfolio -- well, national lending portfolio increased by $112 million or 11% from the linked quarter. And if we go back a year, it increased $207 million or 23% over the past year. And then the final point I want to make on this is that our -- because our loan book grew and we've maintained our rates, our base net interest income, that is before transactional income, increased by $1.7 million from the linked quarter. And so this is -- our plan is that as the corresponding fee over time goes down, we will make up for that and hopefully more -- much more by growing our loan books.
And so with that, let me turn to the correspondent fee for a second. And for this, I would ask you to go to Slide 4. With the correspondent fee income, it went down to the linked quarter -- from the linked quarter from $7.8 million to $6 million in this quarter. And the reason that it went down is the biggest component of the correspondent fee income is on the line called -- or servicing interest, which is our share of the servicing income that is earned by loan source on the loans that they purchased. And that one line item went down by $1.6 million from the linked quarter. And the reason for that is that loans are being forgiven at a very fast clip now.
And to describe that a little bit more, in total, loan source purchased $11.2 billion of loans, and it was the balance at the end of December 31 was $4.6 billion, which is down $2 billion from September 30. And so when those PPP loans get forgiven, there's obviously no servicing income on those, and therefore, that number goes down. They're paying down at roughly the pace of $500 million per month. I suspect that will continue at that pace for a while, and then there'll be some tail to it, but we can expect that over time, the correspondent fee income would go down, I'd say, over time. I suspect most of it will be recognized -- not all of it, but most of it through September 30 of this year.
I want to make a comment on our provision because we had a credit provision of $1.1 million, and that was due to the performance of the SBA portfolio. At the start of COVID, when we looked at the SBA portfolio, which by its nature has higher credit risk on the unguaranteed piece, when COVID started, we put in an additional $3 million on the unguaranteed portion of the SBA portfolio. And fortunately, that portfolio has performed remarkably well. And this quarter, we reversed out about $1.1 million or so from the reserve against that portfolio. But it still is a healthy reserve on it of 5.2%, but it's not the 10% that we previously had.
Noninterest expense, it decreased $2.1 million from the linked quarter to $11.2 million primarily because the linked quarter had $1.6 million of nonrecurring correspondent expenses associated with the wrap-up of the PPP. And so our noninterest expense for the quarter was $11.2 million, and those who'd like to do the modeling, I think that's a pretty good number. You may think about $45 million for the year.
On asset quality, those slides are 10 through 12, again, strong. Delinquencies were $14.6 million or 1.23% of total loans. As I've said before, in the case of our business, particularly around the purchased loans, those delinquencies will look higher than a traditional community bank. And the real question is to look at the charge-offs on our originated loan book, where we've done, I don't know, $1.8 billion or so, in that range. Our charge-offs are, ready? Zero. And in the case of the purchased portfolio, where the returns are, on a weighted average, about 11.5% more or less, the weighted average charge-offs are 8 or 9 basis points and really terrific asset quality. On the COVID deferrals, they virtually all worked out. The ones that we provided a P&I deferral, 99% are current. And in the case of interest-only, they're also performing remarkably well.
So now I want to make a comment on deposits, which are slides 20 through 24. And over the last year, 1.5 years, we've made a conscious effort to reduce our reliance on higher cost bulletin board and able CD and money market deposits with a focus of bringing down that cost by growing our deposits to our Community Banking division, which includes deposits in our footprint, of course, both consumer and business, also meaningful number for deposits from municipalities, which we're trying to -- state and municipalities, which we're continuing to grow as well as a focus on getting deposits from our National Lending customers. And that's really paid off. Our average cost of deposits for the quarter were 36 basis points, which compared to a year ago, it was 103 basis points and 2 years was 198 basis points. Now of course, some of that or a fair amount of that is rate driven. But if you look at the slides, you'll see how we have changed the composition of the deposits.
Also, on the share repurchase activity, I know this is near and dear to a bunch of our investors. For the quarter, we repurchased 340,000 shares at a weighted average price of just under $34. And finally, I want to make a comment on our 7(a) program with NEWITY. As you recall, we signed a 5-year exclusive marketing agreement with NEWITY, which is formally ACAP -- or the people are the same people, I should say more accurately. Again, starting with trying to remarket small balance -- or I should say, starting to market SBA 7(a) loans to most of the 115,000 customers that Loan Source has been purchasing their loans, our first foray is looking at small balance working capital loans under $25,000.
We spent a lot of time along with NEWITY building out the technology, which is substantially complete. We've just -- NEWITY has just started to invite existing Loan Source customers in a phased rollout to apply for these small balance working capital lines. As I said before, I don't want to overpromise or underpromise, we'll see how this performs. We're certainly optimistic, but we will see. And we will have better numbers to report to you after the quarter now when we meet again in April.
And with that, I would like to turn it over to you for questions.
