Okay. Thanks, Tony. Good morning, everyone. Our fourth quarter performance capped an extraordinary year for First Western. We were extremely well positioned to manage through the unprecedented environment created by the COVID-19 pandemic. Our well diversified, conservatively underwritten loan portfolio has experienced very little stress from the pandemic. We capitalized on the PPP program to add new commercial customers and the refi boom caused by the reduction in interest rates enabled us to generate significant profits in our mortgage business that contributed to tremendous internal capital generation and growth in our tangible book value this year.
The one drawback is that a huge increase in mortgage activity during the second and third quarter makes for difficult sequential quarterly revenue and earnings comparisons. But aside from the volatility in that one business, which still had very strong fourth quarter from a historical perspective, we continue to see very positive trends in the areas we're focusing on to build a sustainable path to higher earnings and returns in the future. When looking over our year-to-year comparison, the progress we made in 2020 is exceptionally clear.
During the fourth quarter, our revenue increased 44.2% over the prior year. And with the operating leverage we're realizing as we continue to scale, this revenue growth resulted in 88.6% increase in both net income and earnings per share. Our strong financial performance, combined with the completion of our sale of the LA fixed income team, resulted in a tangible book value per share increasing 25% year-over-year. The primary contributor to this improved performance is the success we're having in growing our balance sheet as our commercial banking initiative continues to produce new relationships, high-quality loans and low-cost deposits. Excluding runoff of PPP loans, our held for investment loans increased 6% from the third quarter, while our total deposits increased 3.6%. This balance sheet growth resulted in our net interest income increasing 4.2% from the prior quarter and 64.3% from the fourth quarter of last year, which fully reflects the contribution of both our organic growth and the addition of clients and banking talent we added through the branch acquisition earlier this year.
With our expanded commercial banking team, we're seeing more commercial loan production and also improving in loan pricing. Our average yield on new commercial loan production in the fourth quarter was the highest we've seen prior to the onset of the pandemic. We're also seeing our increased lending capacity and well differentiated value proposition is allowing us to compete effectively against larger banks. In fact, our largest loan originated this quarter, a $50 million line of credit was a deal that we would not have been able to -- likely not have been able to win in past years. This loan was provided to a longtime client who we've supported for many years when he built his business, and in the fourth quarter, he sold the business for a great deal of money. Following the sale, the client now had investment management account of more than $70 million that need to be placed with a wealth manager and the need for a large credit line that will be secured by the investment management account. Many of the large investment banks and brokers made offers to him, we were able to win the business and expand this relationship into a much more profitable one for First Western. And this plan will have additional needs in the future such as trust services and state planning that will provide additional opportunities for us to grow the relationship.
As an added bonus, his partners in the business were impressed with our services, and we now have opportunities to bring them in as clients as well. In winning this deal, we're clearly able to punch well above our weight class and fully leverage the robust private banking and wealth management platform we've built, and we believe it's a type of deal that we'll continue to win in the future.
Looking at our mortgage activity in the quarter, we had another strong month of production in October. At that point, we built a large backlog of loans that needed to be processed for sale. Given the rapid increase in production volume we saw in the second and third quarter, we ran into some processing constraints, so we slowed down new locks in the -- in order to work through this backlog. Combined with the usual seasonality that we see that reduces demand in November and December, this resulted in a lower level of net gain on the sale of mortgage loans relative to the third and second quarters. But on a year-over-year basis, our Q4 gain was still up 67.6%, and I'll talk more about our expectations for this business later in the call.
From an asset quality perspective, we continue to see very positive trends. Our nonperforming loans -- nonperforming assets declined by 59.3% from the end of the prior quarter, while our loan modifications declined to less than 1% of total loans. We continue to implement enhanced monitoring and portfolio reviews to ensure we have a good understanding of how our borrowers are being impacted by the pandemic, particularly given the surge in cases late in the year. To date, we haven't seen this surge have any material impact on our borrowers or results in new requests for loan deferrals.
Moving now to Slide 4. We continue to see a significant jump in our level of profitability relative to last year. The balance sheet growth and increasing operating leverage we're realizing as we scale continues to demonstrate that the model we built will produce a high level of profitability and returns in the future. The sale of the LA Fixed income team resulted in a valuation allowance being placed against our net operating losses in the state of California. This caused our effective tax rate to be higher in the fourth quarter, which negatively impacted our earnings by $0.05 a share.
Turning to Slide 5. We'll look at the trends in our loan portfolio. Our total loans held for investment increased 26.7% or 1.8% growth from the end of the prior quarter. But if PPP loans are excluded, our total loans increased $89.9 million or 6%. We had total loan production of $201.1 million, up from $142 million last quarter. This was partially offset by $128.1 million of payoffs and paydowns, which is the highest level we saw all year. Most of the growth in the portfolio is due to the traction we're getting in our commercial bank initiative, which included 5 more deals we did in the fourth quarter as part of the main street lending program. And the bankers we added in the Simmons transaction brought some construction lending expertise, so we're seeing more opportunities in that area. Our primary focus will still be on the private bank in commercial loans, but construction represents another driver of loan growth, although we plan to keep the construction -- its contribution to the overall mix in the portfolio pretty consistent over the longer term.
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 progress we're making with our commercial banking initiative. Compared to a year ago, residential mortgage loans have declined from 40.2% of total loans to 29.7% total loans held for investment.
Moving to Slide 6. We'll take a closer look at deposit trends. Our total deposits increased $56.2 million or 3.6% from the end of the prior quarter. There was some volatility in our period end deposits due to fluctuations in the deposits of a title company that keeps large balances with us. Excluding the balances of that one client, our deposit growth was around $74 million. The primary driver of our deposit growth continues to be commercial DDA relationships, which accounted for 65.7% of all our deposit growth during 2020. 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 29.7% of total deposits from 22.1% a year earlier.
Moving to Slide 7. We want to provide some additional insight into the level of commercial loan and deposit growth we're generating. A couple of years ago, we announced our intent to strengthen our commercial banking capabilities as a natural complement to our entrepreneurial-oriented private banking business. This effort is helping our relationship bankers to better serve existing clients and add new relationships with more products and services. We made good progress from an organic standpoint in the branch acquisition during the second quarter accelerated this initiative.
Throughout 2020, this effort contributed strong growth in assets, revenues and earnings. And it's creating a more diversified loan portfolio and a lower cost deposit base that we believe enhances the value of our franchise.
Turning to trust and investment management on Slide 8. Our total assets under management increased by $124.2 million or $454.8 million, if you exclude the assets that were included as part of the sale of the LA Fixed income team. The increase this quarter was due primarily through a combination of improved market conditions, new client accounts 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?
