Thanks, Andy. Turning to Slide 6, we reported diluted earnings per share of $0.49 for the quarter, or $0.99 per share, after adjusting for notable items. Notable items totaled $1.1 billion on a pre-tax basis, or $780 million net of tax, representing a $0.50 reduction per diluted common share, including an FDIC special assessment charge of $734 million, offset by a benefit from tax settlements in the quarter.
Other notable items this quarter included merger and integration costs of $171 million, a charitable contribution to fund our community benefits plan of $110 million, and a balance sheet optimization charge of $118 million. This quarter, we opportunistically restructured a portion of our investment securities portfolio, which we expect will enhance our net interest income trajectory, while also strengthening our capital and liquidity positioning. Slide 7 provides a more detailed earnings summary for the quarter.
Turning to Slide 8, we continued to manage the balance sheet prudently as we saw reduced loan demand this quarter, and the competition for deposits remained heightened as system-wide liquidity declined. Total assets ended the year at $663 billion. Average loans declined 1.1% on a linked quarter basis, as growth in credit card loans, supported by consumer spending and low payment rates, was more than offset by weaker commercial loan demand.
Average deposits declined 1.9% linked quarter. Given our strong deposit balances in the third quarter, we moderated our deposit pricing somewhat in the fourth quarter, even as we grouped consumer deposits by 1%. During the quarter, we rebalanced a portion of our securities portfolio, which provided risk-weighted asset relief and improved our overall earnings trajectory. The average yield on total investment securities portfolio increased 2.97% for the fourth quarter, a 55 basis point increase compared to a year earlier.
As of December 31st, the ending balance on the total investment securities portfolio was $161 billion. During the quarter, effective duration on the available-for-sale portfolio declined to less than three years as unrealized losses, net of tax, improved by approximately $2 billion, given the movement in rates and repositioning.
Turning to Slide 9. Net interest income on a fully taxable equivalent basis declined 3.0% linked quarter, driven by a modest decline in the net interest margin of 2.78%. The 3 basis point decline in the net interest margin reflected market dynamics, including deposit pricing pressure and unfavorable shifts in the deposit mix, partially offset by better earning asset spreads and improved total funding mix. In the first quarter of 2024, we expect net interest income on a fully taxable equivalent basis to be in the range of $4.0 billion to $4.1 billion. For the full year 2024, we expect net interest income on a fully taxable equivalent basis to be consistent with our annualized fourth quarter 2023 net interest income level of approximately $4.14 billion to up slightly.
Slide 10 highlights trends in non-interest income. Non-interest income, as adjusted, increased 12.1% on a year-over-year basis, driven by new account growth and deepening relationships across the business. Year-over-year payment service revenue benefited by continued strength in consumer and business spending activities, while increases in trust and investment management fees and commercial product revenue were driven by underlying market activity, a full fourth quarter with Union Bank, and core growth.
Turning to Slide 11, non-interest expense, as adjusted, decreased by 1.0% on a linked quarter basis, driven by lower compensation-related expense that was partially offset by strategic investments in marketing and business development.
Slide 12 highlights our credit quality performance. Asset quality metrics trended in line with expectations, and key metrics continued to normalize toward pre-pandemic levels. Our ratio of non-performing assets to loans and other real estate was 0.40% at December 31, compared with 0.35% at September 30, and 0.26% a year ago. The fourth quarter net charge-off ratio of 0.49% increased 5 basis points from a third quarter level of 0.44% and was higher when compared to a fourth quarter 2022 level of 0.23%, as adjusted.
Turning to Slide 13, we increased our common equity tier 1 ratio to 9.9% as of December 31. The combination of earnings accretion, net of distributions, and balance sheet optimization actions resulted in a 20 basis point increase linked quarter. Balance sheet optimization activities continued to have a low to neutral impact on earnings and provided additional risk transfer benefits.
As we move into 2024, we expect earnings to be the primary driver of capital accretion with limited reliance on balance sheet capital-related actions. As of December 31, 2023, our common equity tier 1 capital ratio remains above our regulatory capital minimum by 290 basis points.
Let me now hand it back to Andy for closing remarks.
