Thank you, Marty, and good morning, everyone. I'll begin by providing commentary on performance in key areas with comparisons for the fourth quarter of 2021. Net interest income was $39.6 million, $1.3 million lower than the linked quarter, primarily as a result of lower revenue in connection with PPP loans. Approximately $25 million and $64 million of PPP loans were forgiven in the first quarter of 2022 and fourth quarter of 2021, respectively, with related fee accretion of $970,000 in the first quarter as compared to $2.6 million in the linked quarter. Approximately $1 million in 2020 vintage loans and $31 million of the 2021 vintage bonds remain on the balance sheet at quarter end. NIM on a fully taxable equivalent or FTE basis, for the first quarter of 2022 was 311 basis points, down 4 basis points from the linked quarter and down 18 basis points from the first quarter of 2021.
Both PPP and excess liquidity continued to impact NIM. Given the lower level of remaining PPP loans outstanding and associated forgiveness, there was a $1.7 million reduction in PPP interest and fees on a linked quarter basis, resulting in an 11 basis point reduction in NIM. Partly offsetting the PPP impact was a significant reduction in short-term interest-earning deposits of $104 million, which resulted in approximately 6 basis points of NIM expansion in the current quarter. We continue to experience a stable level of cash flow on our investment securities portfolio, which is primarily comprised of mortgage-backed securities with low to moderate duration. These securities provide ongoing cash flow that has generated incremental yield over federal reserve balances. Cash flow from the portfolio allows for reinvestment into loans or additional investment securities as rates have increased.
Our cost of funds was flat at 22 basis points in the current quarter as compared to the linked quarter. Noninterest income of $11.3 million was $352,000 lower than the fourth quarter. Revenue categories of the largest changes quarter-over-quarter were as follows: Insurance income was $754,000 higher, primarily as a result of the timing and level of contingent revenue received in the first quarter each year, combined with growth in the commercial lines business and income from limited partnerships was up $501,000 based on the activity and performance of underlying investments.
We experienced a net loss on the sale of residential mortgage loans of $91,000 compared to a net gain of $482,000 in the previous quarter. Sales volumes and margins have moderated substantially in 2022, and we incurred a loss in the first quarter due to the current fair market value of pipeline commitments. These losses will be recovered when the loans are sold. Income from derivative instruments was down $516,000 based on the number and value of transactions and the impact of changes in fair market value.
Noninterest expense was $238,000 higher than the linked quarter, primarily as a result of higher salaries and employee benefits, driven by investments in personnel, annual merit increases, promotions and the impact of higher payroll taxes incurred in the first quarter each year. Income tax expense was $3.4 million in the quarter, representing an effective tax rate of 18.7% and compared to $4.2 million and an effective tax rate of 17.7% in the fourth quarter of 2021.
Accumulated other comprehensive income decreased by $54 million in the quarter, driven by an increase in the unrealized loss position of our available-for-sale securities portfolio. Intermediate maturities of the treasury curve negatively impacted the market valuation of our investment portfolio due to its 5-year duration. We do not consider any component of this portfolio to be impaired because it is primarily comprised of agency wrapped mortgage-backed securities that are implicitly and explicitly guaranteed by the U.S. government.
The unrealized loss position does not impact our forward earnings metrics as we expect these securities to mature at a terminal value equivalent to par. As these securities rolled down the curve, we continue to redeploy cash flow into the loan portfolio or current coupon bonds.
The decline in AOCI negatively impacted our TCE ratio by 97 basis points in tangible common book value per share by $3.52. The accounting driving this impact is short term given the high quality of our investment portfolio. Over time, we expect our TCE ratio and tangible common book value per share to return to prior levels. We provided slides in our investor presentation available on the Investor Relations website that show the various components of the quarterly change in both of these measures.
I'll now take a few minutes to provide our current outlook for 2022 in key areas. We continue to expect mid- to high single-digit growth in our total loan portfolio with commercial and indirect loan categories driving this growth. Guidance assumes that forgiveness or repayment of the majority of the remaining $31 million of PPP loans during the next 2 quarters. We continue to plan for low single-digit growth in nonpublic deposits. We are focused on attracting new consumer and commercial deposit accounts and expect the positive impact of these new accounts to be partially offset by an expected decline in the average balance per account. Reciprocal and public deposits are projected to be relatively flat, consistent with our experience in the first quarter. We are increasing the top end of our guidance range for full year NIM by 7 basis points. The range is now 305 to 317 basis points, excluding the impact of triplet activity. There will continue to be noise in our NIM relative to PPP forgiveness, although muted relative to 2021. So we continue to guide on NIM, excluding PPP. NIM guidance reflects the increase in the Fed funds rate that occurred in mid-March.
As a reminder, we are guiding them using a spot rate forecast, which was recalibrated with the spot rates as of 3/31. We do expect further interest rate increases. However, the number and magnitude are difficult to predict. We continue to expect a higher investment securities portfolio due to carryover from our 2021 excess liquidity position, which will put pressure on NIM in the first half of 2022 as we deploy liquidity from the investment portfolio into loans. Guidance also reflects our historical experience for deposit betas that range from 0% to 30% for nonmaturity deposits.
As a reminder, our NIM fluctuates from quarter-to-quarter due to the seasonality of public deposits and its impact on both our earning asset and funding mix. In quarters where our average public deposit balances are higher due to seasonal inflows, the second and fourth quarters. Our earning asset yields are lower given the short-term duration of the deposits and limited opportunities to invest the funds.
Our balance sheet remains relatively neutral. We saw a modest level of NIM compression in the first quarter as expected with the lower level of PPP revenue and expect NIM to expand throughout the remainder of the year if the current rate environment persists. Approximately 35% of our loan portfolio, excluding PPP, is indexed to variable interest rates.
We maintain our projection of low single-digit growth in noninterest income, excluding gains on investment securities and noninterest income categories that are difficult to predict, such as limited partnership income. We also expect continued pressure on mortgage banking revenue as a result of lower anticipated refinance activity and tightening of gain on sale spreads due to the interest rate environment.
We continue to expect an increase in the mid-single-digit range for noninterest expense, which is expected to range from $31 million to $32 million per quarter. Q1 expense is lower than guidance due to the timing of certain projects and initiatives that were deferred to the second quarter.
Our spend in 2022 includes investments in strategic initiatives, including further enhancements to our new customer relationship management solution, digital banking and Banking-as-a-Service. We expect these investments to begin producing incremental revenue in 2022. However, full benefits are likely to be realized over the coming years.
Our expectations for efficiency ratio remains the same within a range of 59% to 60% for the year. 2022 efficiency ratio is impacted by upfront costs associated with our aforementioned investments and strategic initiatives that we expect to recoup in later periods, driving our expectation for improvement in future efficiency ratio.
We continue to anticipate that the 2022 effective tax rate will fall within a range of 19% to 20%, most likely towards the low end of the range given the first quarter results. Guidance includes the impact of the amortization of tax credit investments placed in service in recent years. We continue to evaluate tax credit opportunities, and our effective tax rate would be positively impacted by taking advantage of further investment opportunities.
We expect net charge-offs to remain within our annual historical range of approximately 35 to 40 basis points. Although first quarter net charge-off activity remains benign, similar to our experience in 2021. Our overall focus includes executing on strategic initiatives that will improve profitability and operating leverage over time. We believe that achieving results in line with the guidance provided, will drive these outcomes.
That concludes my prepared remarks. I'll now turn the call back to Marty.
