Thank you, Harris. Good evening, everyone, and thank you for joining. I'll begin with a discussion of the components of pre-provision net revenue. Over three-quarters of our revenue is from the balance sheet through net interest income.
Slide 7 includes our overview of net interest income and the net interest margin. The chart shows the recent five-quarter trend for both. Net interest income on the bars and the net interest margin in the white boxes were consistent with the prior quarter as the repricing of earning assets kept pace with rising funding costs. Additional detail on changes in the net interest margin is outlined on Slide 8. On the left-hand side of this page, we've provided a linked quarter waterfall chart outlining the changes in key components of the net interest margin. The 14 basis point adverse impact associated with deposits, including changes in both rate and volume was offset by the positive impact of loan repricing and higher money market and securities yields. Non-interest-bearing sources of funds continue to serve as a significant contributor to balance sheet profitability.
The right-hand chart on this slide shows the net interest margin comparison to the prior year quarter. Higher rates were reflected in earning asset yields, which contributed an additional 106 basis points to the net interest margin. This was more than offset by increased deposit and borrowing costs, which when combined with the increased value of non-interest-bearing funding, adversely impacted the net interest margin by 168 basis points. Overall, the net interest margin declined by 62 basis points versus the prior year quarter.
Moving to non-interest income and revenue on Slide 9. Customer-related non-interest income was $150 million, a decrease of 4% versus the prior quarter due to lower loan servicing fees, primarily attributable to the sale of certain mortgage servicing rights recognized in the third quarter. The remainder of customer-related fees were relatively in line with the prior year as year-over-year decrease in capital markets revenue was offset by improved commercial account fees. Within capital markets, customer interest rate swap related revenue in 2023 was adversely impacted by loan demand and the interest rate environment. This headwind was largely offset as investment in new product capabilities has resulted in growth in other sources of capital markets revenue. We remain confident that we are poised for meaningful growth in capital markets activity and revenue. Our outlook for customer-related non-interest income for the full year of 2024 is moderately increasing relative to the full year 2023.
The chart on the right side of this page includes adjusted revenue, which is the revenue included in adjusted pre-provision net revenue and is used in our efficiency ratio calculation. Adjusted revenue decreased 16% from a year ago and decreased by 2% versus the third quarter due to the factors noted previously.
Adjusted non-interest expense, shown in the lighter blue bars on Slide 10, was essentially flat to the prior quarter at $489 million. Reported expenses at $581 million increased $85 million due to the $90 million in FDIC special assessment costs recognized in the quarter. Our outlook for adjusted non-interest expense is slightly increasing in 2024 relative to 2023. Risks and opportunities associated with this outlook include our ability to manage technology and employment costs.
Slide 11 highlights trends in our average loans and deposits over the past year. On the left side, you can see that average loans increased slightly in the current quarter. As loan demand remained soft, our expectation is that loans will be stable at year-end '24 when compared to year-end '23.
Now turning to deposits on the right side of this page. Average deposit balances in the fourth quarter increased slightly as growth in customer deposits were offset by declines in broker deposits. The cost of deposits shown in the white boxes increased during the quarter to 206 basis points from 192 basis points in the prior quarter. As measured against the fourth quarter of 2021, the repricing beta on total deposits, including broker deposits, and based on average deposit rates in the fourth quarter was 39% and the repricing beta for interest-bearing deposits was 60%.
Slide 12 includes a more comprehensive view of funding sources and total funding trends. The left side of the chart includes ending balance trends. Short-term borrowings have decreased $8 billion since the first quarter of 2023, as customer deposits have grown and earning assets have declined. On the right side, average balances for our key funding categories are shown along with the total cost of funding. As seen on this chart, the rate of increase in total funding cost at 15 basis points in the current quarter has continued to decline compared to the prior three quarters.
Slide 13 shows non-interest-bearing demand deposit volume trend, you can see that the recent trend in demand deposit attrition appears to be flattening. Although demand deposit volumes have been declining over the past six quarters as customers move into interest-bearing alternatives, the contribution to the net interest margin shown in the white boxes, and, therefore, the value of the demand deposit portfolio has increased.
Moving to Slide 14. Our investment portfolio exists primarily to be a ready storehouse of funds to absorb customer-driven balance sheet changes. On this slide, we show our securities and money market investment portfolios over the last five quarters. The investment portfolio continues to behave as expected. Maturities, principal amortization and prepayment-related cash flows were over $700 million in the third quarter. With this somewhat predictable cash flow, we anticipate that money market and investment securities balances combined will continue to decline over the near term, which will be a source of funds for the balance sheet.
The duration of the investment portfolio, which is a measure of price sensitivity to changes in interest rates, is slightly shorter compared to the prior year period, estimated at 3.6% currently versus 4.2% one year ago. This duration helps to manage the inherent interest rate risk mismatch between loans and deposits. With a larger deposit portfolio assumed to have a longer duration than our loan portfolio, fixed rate term investments are required to balance asset and liability duration.
Moving to Slide 15. We've provided the projected trend of AOCI, accumulated other comprehensive income, in -- based on an expected accretion and interest rate impacts based on the forward curve as of December 31. AOCI improved to $2.7 billion, from $3.1 billion in the prior year, largely due to principal amortization in the securities portfolio, combined with interest rate swap maturities. We expect based on the current forward curve that AOCI will decline by about $900 million cumulatively over the next eight quarters.
Slide 16 provides information about our interest rate sensitivity, which differs in content and format compared to prior quarters. While we provided standard parallel interest rate shock sensitivity measures in the appendix of this presentation, we believe a more dynamic view of interest rate sensitivity is most relevant in the current environment. Noted in the bar chart on the far-right side of this page, modeled net interest income in the fourth quarter of 2024 is 2.4% higher when compared to the fourth quarter of 2023 using the implied forward path of interest rates at year-end and assuming a static balance sheet. 100 basis point parallel up and down shocks of this implied forward outcome suggests about 2% of interest rate sensitivity around that figure. This modeled analysis reveals that our balance sheet, while asset-sensitive using traditional measures, is positioned for net interest income growth if short-term rates fall faster than long-term rates.
Utilizing this model outcome and overlaying management expectations for balance sheet changes and deposit pricing, we believe that net interest income will -- in the fourth quarter of 2024, will be stable to slightly increasing when compared to the fourth quarter of 2023. Our outlook is that full year net interest income will be slightly decreasing in 2024 when compared to 2023. Risks and opportunities associated with this outlook include realized loan growth, competition for deposits and the path of interest rates across the yield curve.
Moving to Slide 17. Credit quality remains strong. Classified loans increased $56 million, driven by the commercial real estate portfolio, while non-performing assets decreased $4 million. Net charge-offs were 6 basis points of loans in the quarter. Loan losses in the quarter were somewhat granular and largely associated with our commercial loan portfolio. The allowance for credit losses is 1.26% of loans, a 4 basis point decrease over the prior quarter due to a modest improvement in our economic outlook.
As we know, it is a topic of interest, we have included information regarding the commercial real estate portfolio with additional detail included in the appendix of this presentation. Slide 18 is a reminder of the discipline we have maintained over the past decade as it relates to the commercial real estate portfolio growth. We have chosen our partners carefully and our growth has remained well below peers over time.
Slide 19 provides an overview of the commercial real estate portfolio. CRE represents 23% of our loan portfolio, with office representing 15% of total CRE or 3% of total loan balances. Credit quality measures for the total CRE portfolio remained relatively strong, though criticized and classified levels increased in the quarter. Overall, we continue to expect the CRE portfolio to perform well with limited losses based on the current economic outlook.
Our loss absorbing capital position is shown on Slide 20. The CET1 ratio continued to grow in the third quarter to 10.3%. This, when combined with the allowance for credit losses, compares well to our risk profile as reflected in the low level of ongoing net charge-offs. We expect to maintain solid regulatory capital while managing to a below-average risk profile.
Slide 21 summarizes the financial outlook provided over the course of this presentation. As a reminder, this outlook represents our best current estimate for the financial performance for the full year of 2024 as compared to 2023.
This concludes our prepared remarks. As we move to the question-and-answer section of the call, we request that you limit your questions to one primary and one follow-up question to enable other participants to ask questions. Camilla, please open the line for questions.
