Thank you, Harris, and good evening, everyone. I'll begin with a discussion of the components of PPNR, approximately 80% of our revenue is from the balance sheet through net interest income. Page seven is an overview of net interest income and the net interest margin. The chart on the left shows the recent five-quarter trend for both net interest income on the bars and the net interest margin in the white boxes lost ground in the first-quarter for the first time [Technical Issue] The right-hand side of the chart shows the linked-quarter effect of certain items on the net interest margin, higher rates helped to improve our earning asset yield by 40 basis points, as we saw more depositor sensitivity to the higher interest-rate environment. We increased the roll rate on overall -- we've increased the rate on overall deposits by 50 basis points relative to the fourth quarter. Our borrowed funds also increased, which when combined with the higher-cost of deposits increased the total cost of interest-bearing funds by 95 basis points. This degree of core deposit sensitivity therefore resulted in a 55 basis-point contraction in our interest-rate spread. However, over 40% of our earning assets are funded with non-interest bearing sources of funds. The 50 basis-point contraction in interest-rate spread was therefore partially offset by an increase of 35 basis-points in the value of non-interest bearing funds in a higher-rate environment. These factors combined to produce a 20 basis-point contraction in the net interest margin in the first quarter when compared to the fourth quarter. I'll say more about recent trends in balance sheet yields in just a few minutes.
Moving on to noninterest income and revenue on Page eight. Customer-related noninterest income was $151 million, a decrease of 1% versus the prior quarter and flat to the prior year. As we noted last quarter, we modified our non sufficient funds and overdraft fee practices near the beginning of the third quarter of 2022, which has reduced our noninterest income by about $3 million per quarter. Improvement in treasury management fees has allowed us to make-up some of that lost revenue. Our outlook for customer-related noninterest income for the first quarter of 2024 is moderately increasing relative to the first quarter of 2023.
On the right-side of the page, revenue, which is the sum of net interest income and customer-related noninterest income is shown. Revenue grew by 19% from a year ago and when excluding PPP revenue, it grew by 24% over the same-period. Noninterest expense on Page nine increased 9% from the prior quarter to $512 million. The base period, the fourth quarter of 2022 was positively impacted by an incentive compensation reversal of $8 million. While the first quarter of 2023 included seasonal items such as stock-based compensation for retirement-eligible employees and payroll taxes of $24 million, the cost of FDIC insurance was also up $4 million versus the fourth quarter, while expenses were up in the first quarter, you can see on this page that our efficiency ratio improved by nearly six percentage points when compared to the same quarter one year ago. Our outlook for adjusted noninterest expense is now stable, as we expect expenses in the first-quarter of next year to be flat to the first-quarter of 2023.
Page 10 highlights trends in our loans and deposits over the past year. The rate of growth in loans slowed in the first quarter as seen in the period-end numbers as opposed to the average shown on this page. Our expectation is that loans will increase slightly in the first quarter of 2024 when compared to the first quarter of 2023. Deposits have continued to the trend we reported throughout 2022. As I will discuss in a few minutes, there is a market difference in the sensitivity of larger uninsured deposits when compared to smaller insured deposits. Larger depositors are more sensitive to higher rates and as we have moved deeper into the interest rate cycle, deposit repricing betas have accelerated. As discussed in our last earnings call, we have become more aggressive on deposit rates, which we expect will help to attract some of the larger balances that have moved off-balance sheet in search of higher yields.
For the quarter, our cost of total deposits increased to 47 basis-points, up from 20 basis-points in the prior quarter. At the end of the quarter, the spot cost of total deposits was 90 basis-points with interest-bearing deposits yielding 1.63%. Our deposit beta at the end-of-the quarter was 18% when compared to the fourth quarter of 2021. These changes when combined with the continued improvement in loan yields resulted in an estimated net interest margin of about 3% point in time at the end of the first quarter. I will provide additional details on the composition and performance of our deposit portfolio over the next few pages.
Beginning with Page 11. As shown here, commercial deposits are about one-half of our deposits with consumer deposits contributing about one-third total deposits and brokered [indecipherable] deposits, rounding out the portfolio. Not surprisingly, due to deposit size, two-thirds of our commercial deposits are not insured. However, over 60% of those deposits are tied to the bank through operating account relationships, due to the operational nature of these deposits, we view these deposits as being less rate-sensitive than other large deposits.
Page 12, provides a view of changes in deposit balances in the first-quarter when compared to the prior quarter-end by balanced here. As we have observed over the past year, deposit size and activity are key drivers of deposit sensitivity. We believe that recent changes in deposit pricing will provide a compelling on-balance sheet option, particularly for large deposits.
Page 13 shows the deposit portfolio by FDIC insurance status. The chart on the left shows, we reported a notable increase in uninsured deposits throughout 2020 and 2021 and has been previously reported those deposits have been falling back toward historical levels. Likewise, our loan-to-deposit ratio on the right-side of the page, it's moving to be in-line with the pre pandemic level. Since the end of 2019, total deposits are up 21%, and are up 18%, excluding brokered deposits. Page 14 compared the total amount of uninsured deposits where we have observed more depositor sensitivity to the aggregate amount of secured and available sources of funds. As shown here, the current level of demonstrated sources of funds handily exceeds the entire volume of uninsured deposits. I will preemptively respond to an expected question, we did not access the Federal Reserve discount window nor the new bank term funding program in the first-quarter, except for an operational test of the BTFP consisting of a $1 million overnight advance.
Moving to page 15, our investment portfolio exits primarily to be ready source of funds to facilitate client-driven balance sheet changes. On this page, we show our securities and money market investment portfolios over the last five quarters. The size of the investment portfolio declined versus the previous quarter, but as a percent of earning assets, it remains larger than it was immediately preceding the pandemic. This portfolio has behaved as expected. The principal and prepayment related cash flows were just over $800 million in the first-quarter. With this predictable portfolio of cash flow, we anticipate that money market and investment securities balances combined will continue to decline over the near-term, which will in turn create a source of funds for the rest of the balance sheet. Perhaps more importantly, the composition of the investment portfolio allows us to secure funding without the need to sell any of the investment securities. This was achieved primarily through a mechanism, known as the General Collateral Financing or GCF Repo. In this very deep and liquid market, high-quality collateral is pledged and program participants exchange funds anonymously through a third-party clearing and guaranteeing settlement, meaning that the value of the collateral is recognized by all as the sole component of risk assessment.
The duration of the investment portfolio is virtually unchanged from the same prior year period at 4.1 years currently versus 4.0 years a year-ago. This duration helps to manage the inherent interest-rate mismatch between loans and deposits with loan durations estimated to be 1.8 years and the larger deposit portfolio duration estimated to be 2.9 years, fixed-rate term investments are required to bring balance sheet -- to bring balance to asset and liability durations and thus protect the economic value of shareholders' equity.
Page 16 provides information about our interest-rate sensitivity. As a reminder, we have been using the terms latent interest-rate sensitivity and emergent interest-rate sensitivity to describe the effects on net interest income of rate changes that have occurred as well as those have yet to occur, as implied by the shape of the yield curve. Importantly, the balance sheet is assumed to remain unchanged in size in these descriptions. Regarding latent sensitivity, the in-place yield curve as of March 31, which was notably more inverted than the curve at December 31, will work through our net interest income over time. The difference from the prior-period disclosures of latent sensitivity in addition to the shape of the yield curve is the accelerated funding cost beta, which we discussed on last quarter's call. These factors are model to result in a net interest income decline of nearly 7% in the first-quarter of 2024 when compared to the first-quarter of 2023.
Regarding emergent sensitivity, if the March 31st 2023 forward path of interest rates were to materialize and using a stable size balance sheet, the emergent sensitivity measure indicates a decline in net interest income of an additional 1% in the first-quarter of 2024 when compared to the first-quarter of 2023. With respect to our traditional interest-rate risk disclosures, our estimated interest-rate sensitivity to a 100 basis-point parallel interest-rate shock using a same sized balance sheet has increased by about one percentage point from the fourth quarter. As the composition of the balance sheet changes, we actively manage our interest-rate risk through changes in the investment portfolio or through our cash-flow swaps. We have recently begun to reduce asset duration through the unwinding of interest-rate swaps. As a reminder, this traditional interest-rate risk disclosure represent a parallel and instantaneous shock while the latent and emergent views reflect the prevailing yield curve at March 31st.
Our outlook for net interest income for the first-quarter of 2024 relative to the first-quarter of 2023 is moderately decreasing. More immediately, we expect the recent acceleration of deposit repricing beta and balance sheet changes to reduce net interest income by about 7% in the second quarter when compared to the first quarter. On page 17, we quantify the value of the investment portfolio in managing our interest-rate risk. On the left-hand side of the page, the dark-blue bars show our reported net interest income at-risk measures while the light-blue bars show what net interest income at-risk would be if we did not actively manage interest-rate risk through our investment portfolio and interest-rate swaps, as the bars indicate the difference in the plus 100 -- I'm sorry, plus and minus 200 basis-point parallel shock would move from 13% to 39%, an even larger impact on the risk to economic value of equity due to changes in interest rates can be seen on the right-hand chart. Reported EVE at-risk would move from two percentage point differential to a 49% difference without the moderating impact of our fixed-rate securities and interest-rate swap position. This demonstrates the value of assessing -- this demonstrates the value of assessing the balance sheet holistically rather than through the partial view previously described by Harris.
Our loss-absorbing capital position is shown on Page 18, we believe that our capital position is aligned with the balance sheet and operating risk of the bank, the CET1 ratio continued to grow in the first-quarter to 9.9%, this compares well to a very low-level of ongoing net charge-offs. As the macroeconomic environment has become more uncertain, we do not expect to repurchase shares in the second quarter. Our goal continues to be to maintain a CET1 ratio slightly above peer median, while managing to a below average-risk profile.
Page 19 provides an illustrative outlook for accumulated other comprehensive loss. The unrealized loss associated with the investment portfolio and cash flow interest-rate swaps will reverse as these portfolios pay-down and mature. These changes are expected to approve -- improve the other -- the accumulated other comprehensive loss position by nearly $1 billion by the end of 2024, all things equal, this would add 110 basis-points to the common equity ratio and would add just under $7 to book-value per common share.
I will now turn the call over to Michael Morris, our Chief Credit Officer, for a discussion of credit, and in particular, commercial real estate. Michael?
