Thank you, Keith. I will begin by reviewing our first quarter results before turning the line back to the operator to open the call for questions.
Turning to Slide 4. In the first quarter, deposits were relatively flat compared to the $4.1 billion from the fourth quarter of 2018, while average deposits for the quarter were $3.9 billion. As Keith discussed, we experience strong organic deposit growth in the quarter when adjusting for the short-term deposits which came on to our balance sheet at year-end 2018 and exited on January 2, 2019. This organic growth was well ahead of our expectations, which we outlined on our fourth quarter earnings call.
Noninterest-bearing deposits increased $144 million from the prior quarter and now represent 41.6% of average deposits at quarter end. Of note, our deposit beta continues to be low throughout the first quarter as our cost of funds increased only 4 basis points to 31 basis points, representing the continued value of our unique deposit franchise.
Deposits from politically active customers, such as campaigns, PACs and state and national party committees, increased $89 million from $182 million at December 31, 2018, ending the quarter at $271 million, as outlined on Slide 5. As Keith touched on, we anticipate our political deposits to continue to trend upward as we near the 2020 presidential election. As campaigns are launched within the Democratic Party, we continue to actively support the business needs of these individuals and their campaigns.
As seen on Slide 6, we delivered fourth quarter loan growth of $56.4 million or 7.0% annualized as compared to the fourth quarter of 2018 and ended the quarter with $3.3 billion of total loans. Loan growth was driven primarily by a $93.3 million increase in residential first liens and PACE loans offset by continued strategic reduction in our indirect C&I portfolio of $29.3 million and a $12.2 million reduction in commercial real estate.
Our indirect C&I portfolio totaled $203 million at the end of the first quarter. We have seen a recovery in the syndicated and leverage lending credit markets since our last earnings update and have taken advantage of this recovery. Through a combination of sales and payoffs, we have reduced our indirect C&I balances by approximately $127 million since the end of the first quarter of 2019. Details of our remaining indirect C&I portfolio are outlined on Page 7 of the presentation.
The remaining portfolio is approximately $80 million with $69 million in leverage loans and $11 million in nonleverage loans. The remaining portfolio is expected to run off at a more gradual pace.
Skipping ahead to Slide 9, our net interest margin was 3.65% for the quarter compared to 3.57% in the fourth quarter of 2018 or 3.64% on an adjusted basis and 3.43% in the year-ago quarter.
Our NIM expansion was better than expected resulting from a year-over-year increase in average loans and securities of $375 million and $276 million, respectively, and an increase in yields of 29 and 54 basis points, respectively.
Net interest income for the first quarter of 2019 was $40.8 million, which compares to $40.2 million in the linked quarter and an approximately $8.0 million increase as compared to $32.8 million in the same quarter of 2018.
Yield on average earning assets was 4.10% for the first quarter, an increase of 31 basis points as compared to the same period in 2018 driven by an increase in yields due to higher market rates. The yield on our total loans increased to 4.44% compared to 4.32% during the fourth quarter of 2018, an increase of 12 basis points, or 2 basis points after adjusting for the impact of the accounting adjustment in the fourth quarter of 2018.
Now on to noninterest income. Noninterest income for the first quarter of 2019 was $7.4 million, decreasing slightly from $7.6 million in the fourth quarter of 2018 and a $400,000 increase compared to the first quarter of 2018. The year-over-year increase was primarily due to higher gains on the sale of investment securities of $300,000 in the first quarter of 2019 compared to a loss of $100,000 in the year-ago comparable period, combined with modest increases in trust department fees, service charges on deposit accounts and other income.
In April, we have distributed $60 million in cash back to holders of our real estate fund that is winding down and expect income that we receive from that fund to decrease by approximately $50,000 per month going forward. This decline is in line with our estimates for 2019 and included in our previous guidance.
Turning to Slide 10. Noninterest expense for the first quarter of 2019 was $31.4 million, which compares to $35 million in the fourth quarter of 2018 and $28.8 million in the first quarter of 2018. This contributed to a reduction in our efficiency ratio this quarter. We will continue to implement initiatives to reduce our expenses, including reviewing our most significant vendor contracts and identifying opportunities for continued real estate cost savings. Looking forward, we will continue to aggressively manage our expenses as we strive to improve our cost structure.
Skipping ahead to Slide 12. The credit quality of our portfolio held steady throughout the fourth quarter after adjusting for the charged-off C&I loan as nonperforming assets totaled $56.6 million or 1.15% of period-end total assets at March 31, 2019, which was a decrease of $2.7 million from the linked quarter. The nonperforming assets include $7.2 million of loans 90 days past due and accruing, which are primarily related to the delay in renewal for 1 borrower on 4 loans.
The provision for loan losses in the first quarter of 2019 was $2.2 million, which compares to $864,000 of provision in the fourth quarter of 2018. The provision expense in the first quarter was primarily driven by increased provision on the C&I portfolio. As previously reported, there was 1 indirect C&I leverage loan of $8.4 million that was charged off during the first quarter which was fully reserved and had a minimal impact on our P&L. The provision expense was partially offset by a $600,000 release in the off-balance-sheet reserve, which is a reduction in other expenses within total noninterest expense.
Turning to Slide 13. The allowance for loan losses decreased $5.8 million to $31.4 million at March 31, 2019, from $37.2 million in the linked quarter primarily driven by the charge-off of $8.4 million and partially offset by increasing allowance on 2 leverage loans in increasing factors related to the charge-off. The increase was offset by a release of the previously mentioned off-balance-sheet provision of $600,000, which is reported through our noninterest expense.
At March 31, 2019, the bank had $48.1 million of impaired loans, for which a specific allowance of $1.5 million was made, compared to $58.3 million of impaired loans in the linked quarter, for which a specific allowance of $9.6 million was made. The ratio of allowance to total loans was 95 basis points at March 31, 2019, and 115 basis points at December 31, 2018.
Turning to Slide 14. Our GAAP and core return on tangible common equity were 10.31% and 10.18% respectively. The core return compares to 9.50% for the fourth quarter of 2018 and 9.46% for the comparable period in 2018. The increase in core return on tangible common equity in the linked quarter was primarily due to the previously discussed factors. Lastly, we remain well capitalized to support future growth.
To conclude, we are extremely pleased with our performance during the first quarter and are optimistic about the outlook for the remainder of the year. Given that we are still early in the months of 2019, we are not making adjustments to our 2019 outlook. We plan to provide an update on our 2019 guidance on the second quarter call as appropriate.
Thank you, again, for your time today. We look forward to updating everyone on the second quarter results in July.
With that, I'd like to ask the operator to open up the line for any questions. Operator?
