Thanks, Andy. Turning to slide 8, we ended the quarter with total average assets of $664 billion and total average loans of $377 billion, down $9 billion and $12 billion respectively on a linked quarter basis as we prudently managed and optimized our balance sheet, given the current macroeconomic and regulatory environment. Average total deposits were $512 billion, representing a 3% increase linked quarter, driven by expected seasonality and growth in money market and time deposits -- time deposit accounts. Specifically, average noninterest bearing deposits decreased $16.2 billion this quarter, primarily driven by our Union Bank retail customer upgrade at conversion from noninterest bearing checking accounts to our interest-bearing bank smartly product.
Excluding this reclassification, the decrease would have been $6.2 billion. Our mix of noninterest bearing to interest bearing deposits was approximately 19%, consistent with where we expect the mix shift to stabilize, based on historical performance and the operational nature of our core deposit base.
Slide 9 provides an update on the investment securities portfolio. As of September 30th, our available for sale securities were 97% of our total securities. We continued to reduce the effective duration of the AFS portfolio, which is now less than three and a half years.
On slide 10, we provide a detailed earnings summary for the quarter. This quarter, we reported diluted earnings per share of $0.91, or $1.05 per share, after adjusting for merger and integration charges of $213 million net of tax, or $0.14 per diluted common share.
Turning to slide 11, net interest income on a fully taxable equivalent basis totaled approximately $4.3 billion, which represented a 4.1% decrease on a linked quarter basis and a 10.7% increase from a year ago, due to the impact of rising rates and the acquisition of Union Bank. Our net interest margin declined 9 basis points to 2.81% in the third quarter. The linked quarter decline was primarily due to the impact of lower earning assets, deposit pricing and mix shift, offset somewhat by better loan spreads and funding mix.
Slide 12 highlights trends in noninterest income. Fee income increased 11.9% or $295 million on a year-over-year basis, driven by higher payment service revenue, trust and investment management fees, commercial products and mortgage banking revenues.
On a linked quarter basis, fee income increased 1.4%, or $38 million, driven by other revenues, which included servicing revenue from previously executed balance sheet optimization actions.
Turning to slide 13, reported noninterest expense for the quarter totaled $4.5 billion, which included $284 million of merger and integration related charges. Noninterest expense as adjusted decreased $13 million, or 0.3% on a linked quarter basis, driven by lower compensation expense that was somewhat offset by our investments in marketing and business development.
Slide 14 shows our credit quality performance this quarter. While asset quality metrics reflecting changing conditions in the commercial real estate office segment, results this quarter continued to trend in line with our expectations, and key metrics remain below pre-pandemic levels.
Importantly, given the higher interest rate environment as well as other portfolio considerations, we increased our reserve ratio for commercial real estate office loans to 10%. Our ratio of nonperforming assets to loans and other real estate was 0.35% at September 30th, compared with 0.29% at June 30th and 0.20% a year ago.
Our third quarter net charge off ratio of 0.44% increased 9 basis points from a second quarter level of 0.35% as adjusted, and was higher when compared to a third quarter 2022 level of 0.19%. Our allowance for credit losses as of September 30th totaled $7.8 billion, or 2.08% of period end loans.
Turning to slide 15, we continue to take action to improve our capital ratios this quarter, increasing our CET1 ratio to 9.7% as of September 30th. The combination of our debt-to-equity conversion with MUFG, earnings, accretion netted distributions, and balance sheet optimization actions resulted in a 60-basis point increase from last quarter. Importantly, our CET1 capital ratio is now 270 basis points above our regulatory capital minimum.
I will now provide fourth quarter forward looking guidance on slide 16. In the fourth quarter, we expect net interest income of between $4.1 billion and $4.2 billion. Total revenue, as adjusted is estimated to be in the range of $6.8 billion to $6.9 billion including approximately $65 million of purchase accounting accretion.
Total noninterest expense, as adjusted, is expected to be approximately $4.2 billion inclusive of approximately $115 million of core deposit intangible amortization related to Union Bank acquisition. On a core basis, we expect full year 2024 expenses to be flat with 2023.
Our income tax rate is expected to be approximately 23% on a taxable equivalent basis. We expect merger and integration charges of between $250 million to $300 million in the fourth quarter.
I'll now hand it back to Andy for closing remarks.
