Net interest income decreased $93 million, or 14%, in the first quarter of 2024, relative to the prior year period, as higher funding costs offset higher earning asset yields. The net interest margin was 2.94%, compared with 3.33%, and was up from 2.91% in the fourth quarter of 2023.

The yield on average interest-earning assets was 5.25% in the first quarter of 2024, an increase of 76 basis points, reflecting higher interest rates and a favorable mix change to higher yielding assets. The yield on average loans and leases increased 76 basis points to 6.06%, and the yield on average securities increased 38 basis points to 2.84% in the first quarter of 2024.

The rate paid on total deposits and interest-bearing liabilities was 2.34%, compared with 1.17% in the prior year quarter, and the cost of total deposits was 2.06%, compared with 0.47%, also reflecting the higher interest rate environment as well as reduced noninterest-bearing deposits.

Net interest income was also impacted by reduced interest-earning assets and an increase in interest-bearing liabilities. Average interest-earning assets decreased $2.2 billion, or 3%, from the prior year quarter, driven by declines of $2.5 billion and $1.5 billion in average securities and average money market investments, respectively. The decrease in average securities was primarily due to principal reductions. These decreases were partially offset by an increase of $1.8 billion in average loans and leases.

Average interest-bearing liabilities increased $6.0 billion, or 12%, from the prior year quarter, driven by an increase of $12.0 billion in average interest-bearing deposits, as customers moved from noninterest-bearing to interest-bearing products in response to the higher interest rate environment. This increase was partially offset by a decrease of $6.0 billion in average borrowed funds.

Customer-related noninterest income remained flat at $151 million. An increase in capital markets fees, driven largely by improved real estate capital markets and securities underwriting activity, was partially offset by a decrease in loan-related fees and income, primarily due to higher gains on loan sales in the prior year period and a decline in loan servicing income resulting from the sale of associated mortgage servicing rights in the third quarter of 2023.

Dividends and other income decreased $5 million, primarily due to higher mark-to-market valuation adjustments related to servicing rights in the prior year quarter and a decrease in dividends on FHLB stock. Net securities gains decreased $3 million, due to a $4 million valuation loss associated with one of our equity investments in the current period. These decreases were offset by a $4 million increase in fair value and nonhedge derivative income, primarily due to credit valuation adjustments on client-related interest rate swaps.

Total noninterest expense increased $14 million, or 3%, relative to the prior year quarter. Deposit insurance and regulatory expense increased $16 million, driven largely by a $13 million accrual associated with an updated special assessment estimate by the FDIC during the current quarter. Technology, telecom, and information processing expense increased $7 million, or 13%, primarily due to increases in software amortization expenses associated with the replacement of our core loan and deposit banking system, as well as other related application software, license, and maintenance expenses. Salaries and employee benefits expense decreased $8 million, or 2%, primarily due to a decline in incentive compensation accruals.

Adjusted noninterest expense remained relatively flat at $511 million. The efficiency ratio was 67.9%, compared with 59.9%, primarily due to a decline in adjusted taxable-equivalent revenue. For information on non-GAAP financial measures, see pages 16-17.

Total investment securities decreased $2.4 billion, or 10%, to $20.2 billion at March 31, 2024, due largely to AFS and HTM principal reductions. The trading securities portfolio, comprised of municipal securities, totaled $59 million at March 31, 2024, compared with $12 million at March 31, 2023.

We invest in securities to actively manage liquidity and interest rate risk and to generate interest income. We primarily own securities that can readily provide us cash and liquidity through secured borrowing agreements without the need to sell the securities. Our fixed-rate securities portfolio helps balance the inherent interest rate mismatch between loans and deposits and protects the economic value of shareholders' equity. At March 31, 2024, the estimated duration, which measures price sensitivity to interest rate changes, of our securities portfolio was 3.6 percent, compared with 4.1 percent at March 31, 2023. The decline was primarily due to the addition of fair value hedges of fixed-rate securities during the second quarter of 2023.

Loans and leases, net of unearned income and fees, increased $1.8 billion, or 3%, to $58.1 billion at March 31, 2024, relative to the prior year quarter. Consumer loans increased $1.2 billion from the prior year quarter, primarily in the 1-4 family residential portfolio, and commercial real estate loans increased $0.7 billion, primarily in the multi-family and industrial construction loan portfolios. Increased funding of construction lending commitments and a slower pace of loan payoffs contributed to growth in these portfolios. Unfunded lending commitments decreased $1.2 billion, or 4%, to $29.5 billion at March 31, 2024, primarily due to draws on existing commercial and consumer construction lending commitments.

During the first quarter of 2024, we recorded a $13 million provision for credit losses, compared with a $45 million provision during the prior year period. The allowance for credit losses (“ACL”) was $736 million at March 31, 2024, compared with $678 million at March 31, 2023. The year-over-year increase in the ACL reflects declines in credit quality, incremental reserves associated with portfolio-specific risks including commercial real estate, and loan growth. The ratio of ACL to total loans and leases was 1.27% at March 31, 2024, compared with 1.20% at March 31, 2023.

Net loan and lease charge-offs totaled $6 million, compared with zero net charge-offs in the prior year quarter. Classified loans increased $54 million, or 6%. Nonperforming assets increased $81 million, or 47%, primarily in the commercial and industrial and term commercial real estate portfolios.

Total deposits increased $5.0 billion, or 7%, from the prior year quarter, as a $10.9 billion increase in interest-bearing deposits was partially offset by a $5.8 billion decrease in noninterest-bearing demand deposits, as customers moved to interest-bearing products in response to the higher interest rate environment.

At March 31, 2024, customer deposits (excluding brokered deposits) totaled $69.9 billion, compared with $63.8 billion at March 31, 2023, and included approximately $7.5 billion of reciprocal deposits. Our loan-to-deposit ratio was 78%, compared with 81% in the prior year quarter.

Total borrowed funds, consisting primarily of secured borrowings, decreased $7.3 billion, or 57%, from the prior year quarter, due largely to an increase in interest-bearing deposits and a decrease in interest-earning assets. The decrease in long-term debt was due to the maturity of a senior note during the second quarter of 2023.

The common stock dividend was $0.41 per share, unchanged from the first quarter of 2023. Common shares outstanding decreased 0.4 million from the first quarter of 2023, primarily due to common stock repurchases. During the first quarter of 2024, we repurchased 0.9 million common shares outstanding for $35 million, compared with 0.9 million common shares repurchased for $50 million during the prior year period.

Accumulated other comprehensive income (loss) (“AOCI”) was $2.6 billion at March 31, 2024, and largely reflects a decline in the fair value of fixed-rate available-for-sale securities as a result of changes in interest rates. Absent any sales or credit impairment of these securities, the unrealized losses will not be recognized in earnings. We do not intend to sell any securities with unrealized losses. Although changes in AOCI are reflected in shareholders’ equity, they are excluded from regulatory capital, and therefore do not impact our regulatory capital ratios.

Estimated common equity tier 1 (“CET1”) capital was $6.9 billion, an increase of 5%, compared with $6.6 billion in the prior year period. The estimated CET1 capital ratio was 10.4%, compared with 9.9%. Tangible book value per common share increased to $29.34, compared with $24.85, primarily due to an increase in retained earnings and an improvement in AOCI due largely to paydowns on securities.
