I would now like to turn the conference over to Alerus Financial Corporation's Chairman, President and CEO, Randy Newman. Please go ahead
All right. Thank you, Randy. Good morning, everyone. Thank you for joining our call today. I'll briefly walk through some of the highlights for the quarter. And then as Randy mentioned, I'll turn it over to Karin to provide an update on credit-related matters and provisioning and our COVID response.
Let's start with mortgage. Results for the quarter were simply stunning. Originations exceeded $500 million, and we surpassed the $1 billion mark for the year. This unprecedented volume would not be possible without the long-term investments made by the company in recent years.
From a technology aspect, over 90% of our applications were processed through our digital channel and our printing has been reduced from 200,000 pages to 20,000. From a talent perspective, the company's investment and move to mandatory delivery was extraordinarily well timed as margins are even higher than expected due to the operational constraints facing the industry. Our Alerus team members continued to produce strong purchase volume at levels exceeding 2019. The mix of purchase has moved to less than 50% of the volume, and September was our largest month of [indiscernible] ever in the division. The pipeline for the quarter reached historic levels. The combination of the strong pipeline and the higher margins moved the mark-to-market on the hedge up $6 million in the quarter, bringing the year-to-date change in fair value of the hedge to a gain of over $11 million of the nearly $45 million of revenue that's reported.
We anticipate fourth quarter volume to remain strong, with originations near Q3 levels. However, the application volume declined 12% in September, a trend we do expect to continue with seasonality. As such, we expect the value of the forward pipeline or the hedge to decline in the fourth quarter and into 2021, putting pressure on overall mortgage revenues.
Sticking with the fee income theme, which comprises nearly 65% of total revenue, up from 60% a year ago, our retirement revenue rebounded in the third quarter after exiting the revenue sharing a strategic move to be more consistent with our industry practices. We expect this run rate to be fairly consistent, assuming market conditions are stable. Wealth management revenue also improved in the quarter, and September was the largest month of the year from a new asset standpoint as our advisers continued their proactive outreach to clients in the retirement vertical by leveraging our Salesforce technology investments.
Sticking with the proactive outreach, our business advisers continue to cultivate new PPP client expansion efforts, again, leveraging our technology to track and report these leads. We are pleased with the results so far, including over 1/3 of our 300-plus new PPP clients opening a deposit account with Alerus.
On to the balance sheet, which remains fluent throughout the third quarter. We continued to build the investment portfolio from cash, both with short- and long-term purchases. Cash level did dip at the end of the quarter but returned quickly in October to the $200 million range, consistent with what we see most of 2020.
Line utilization dipped again in the third quarter to historic lows. Deposit balances remained robust. And we had our highest quarter ever of online account openings. Notably, total deposit stores outside of our banking geography exceeds $600 million at the end of the third quarter.
From a net interest margin standpoint, we did have a slight recovery in the quarter. Fees and interest income from PPP loans increased to $3.2 million in the quarter. Excess cash continues to weigh a heavy burden on the NIM despite ongoing decreases in our cost of deposits. We expect the margin to scrape to 3%, excluding the impact of PPP.
Last but not least, expenses for the quarter, which were in line with expectations. Compensation rolls in conjunction with the increase in mortgage originations, a trend we expect will continue into the fourth quarter. Other notables were the decrease in postage, part of our ongoing war on paper, to reduce expenses and move to electronic everything throughout our company. In addition, we did have a normalized adjustment to our provision for off-balance sheet commitments compared to the outsized adjustment that we had in the second quarter.
From an expense outlook, we are very pleased with the progress made thus far by our team members. We are focused on productivity and doing more with less, leveraging our technology and infrastructure to grow our company without adding incremental expense.
So far, we have made the decision not to reopen 2 of our client-facing locations, and we continue to evaluate additional opportunities to exit some of our nonclient-facing locations. We will likely see some noise in the fourth quarter run rate from an expense standpoint as we look to finalize some of those decisions as well as transition a portion of our employees to work permanently from their home office.
As a final point, we are pleased to see our investments in our One Alerus culture, our talent and technology translate into results. Our teams are working with urgency to identify additional opportunities to increase efficiencies and reduce expenses. Although uncertainty remains, it is clear the enterprise value of this company is strong and resilient to incredible challenges.
With that, I'll turn it over to Karin.
