Okay. Thanks, Tony. And good morning, everybody.
We're very pleased with our performance this quarter as we continue to deliver record earnings despite the ongoing impact of COVID-19 pandemic. We continue to execute on the vision that we that we communicated at the time of our IPO in 2018. We're a unique wealth manager built on a private bank platform that was emerging at that time from a period of capital constraint. And we said we would realize strong operating leverage as we grew our balance sheet through both organic growth and acquisition. Investments we've made in both banking talent and technology are having the positive impact we expected on new business development, resulting in the consistent addition of new clients as we take market share and drive growth in both net interest income and noninterest income.
In the third quarter, our gross revenue increased 18% from the prior quarter, resulting in a $9.6 million in net income or $1.20 in earnings per share, both record levels of profitability for the company. We had another very strong quarter of mortgage activity, but outside that area, we're seeing positive contributions across the rest of our operations. Our established offices continue to gain scale and improved profitability for bringing in new clients and ramping up quickly in new markets such as Vail Valley and Broomfield.
One of our goals entering this year has been to build the First Western brand, which we have supported with increased marketing and sales investment, and it's clearly paying dividends. Our marketing efforts are generating more leads. And with the compelling value proposition that we offer, we are having a great deal of success in converting those leads into new client relationships.
Another goal this year, which we talked about on our earnings call in January, was the implementation of our commercial banking initiative that was designed to grow our commercial client base, shift our loan portfolio towards more C&I and commercial real estate loans, and add low-cost transaction deposits. The emergence of the COVID-19 pandemic slowed us down a bit, but over the last 2 quarters, we've seen really positive results from this initiative, particularly after the completion of our branch acquisition in May.
One of the aspects of this transaction that we are particularly excited about was the opportunity in a number of experienced commercial bankers, including the former Colorado market president for Simmons, who's now heading up our commercial banking initiative. We're seeing very encouraging results so far. And the balance sheet growth that we saw in the fourth -- in the third quarter was largely due to the addition of new commercial relationships where we're getting both loans and deposits.
From an offensive standpoint, the current environment has been very favorable for us in terms of growing our client roster and taking business away from larger competitors. At the same time from a defensive standpoint, in terms of managing through the impact of the pandemic, we continue to be well positioned and see good trends in asset quality. With a conservatively underwritten portfolio and very little exposure to industries that have been most impacted by the pandemic, we continue to project very low loss content in our portfolio.
During the third quarter, our total active COVID loan modifications declined by 62% and at September 30 represented just 4% of our total loans. And our nonperforming loans declined by 14% from the end of the prior quarter.
We continue to implement enhanced monitoring and portfolio reviews to ensure that we have a good understanding of how our borrowers are being impacted by the pandemic. For the most part, the information we're getting is very positive and indicates our clients have been able to make adjustments to adapt to the current environment and continue performing well.
With that, let's move over to Slide 4, where we show a significant jump that we've seen this year in terms of our level of profitability. While clearly we're getting a bump this year from our mortgage activity, we're more focused on the balance sheet growth and the improving operating leverage that we've been able to generate. This underscores our success in creating a sustainable path to improving profitability and returns that will enable us to replace the earnings generated from mortgage activity when this refinancing boom inevitably runs its course.
Turning to Slide 5. We'll look at the trends in the loan portfolio. Our total loans held for investment increased $83 million or 23.6% annualized from the end of the prior quarter. We had loan production of $142 million in the quarter, which was partially offset by $83 million in payoffs and paydowns. Most of the growth in the portfolio is due to the traction we're getting in our commercial banking initiative. The year-over-year trend shows the shift in our loan portfolio away from residential loans towards business related loans as a result of the branch acquisition, the relationships added through the PPP program, and the progress we're making with our commercial banking initiative. Compared to a year ago, mortgage loan -- residential mortgage loans have declined from 40% of total loans to 30% of total loans.
Moving on Slide 6. We'll take a closer look at our deposit trends. Our total deposits increased $157 million or 44.4% annualized growth from the end of the prior quarter. The growth was almost entirely attributable to growth in commercial DDA relationships. The increase in DDA relationships has helped offset some of the runoff that we saw in PPP-related deposits as clients deployed those funds. As of September 30, we had just $29 million in PPP-related deposits remaining on our balance sheet. With the success we've had in adding commercial transaction accounts, we've seen significant improvement in our deposit mix, with noninterest-bearing deposits increasing to 30% of total deposits from 21% just a year ago.
Turning to trust and investment management on Slide 7. Our total assets under management increased $379 million and returned above the $6 billion mark. The increase this quarter was primarily due to a combination of improved market conditions and additional contributions made to existing client accounts.
Now I'll turn the call over to Julie for further discussion of our financial results. Julie?
