Thank you. Results for the third quarter 2020 were GAAP revenues of $1.1528 billion, GAAP net income of $159.4 million and diluted earnings per share of $0.60. Adjusted revenues were $1.1562 billion, including the impact of the adoption of the revenue standard 606 and for required deferred revenue adjustments for acquisitions.
Adjusted revenue was up 0.5%. Adjusted operating income increased 5.5%, and adjusted EPS was $1.10, an 18.3% increase over Q3 2019. Adjusted revenue increased 5.4% over $5.4 million over Q3 2019. Our acquisitions contributed $29.8 million in the quarter. Foreign exchange had a favorable impact of $6.5 million or 0.6% in the quarter. Organic revenue decline on a constant-currency basis was 1.4%, driven by some weakness in the DSD asset management and health care businesses. These were offset by strength in the fund administration and the Intralinks businesses.
Adjusted operating income for the third quarter was $448.8 million, an increase of $23.2 million or 5.5% in the third quarter. Foreign exchange had a negative impact of $3.2 million on expenses in the quarter. Adjusted operating margins improved from 37% in the third quarter of 2019 to 38.8% in the third quarter of 2020, driven by lower personnel costs, lower costs-related to independent cost factors, lower out-of-pocket expenses and lower travel expenses. Adjusted consolidated EBITDA, which was defined in Note 3 in the earnings release, was $466.3 million or 40.3% adjusted revenue, an increase of $20.5 million or 4.6% over Q3 2019.
Net interest expense for the third quarter was $54.7 million and includes $3.4 million of noncash amortized financing costs and OID. The average interest rate in the quarter for our amended credit facility and the senior notes was 3.0% compared to 4.84% in the third quarter of 2019 and resulted in interest expense decrease of $43.8 million. We recorded GAAP tax provision for the quarter of $58.6 million or 26.9% of pretax income.
Adjusted net income, as defined in Note 4 of the earnings release, was $294.2 million, and adjusted diluted EPS was $1.10. And the effective tax rate used for adjusted net income was 26%. Diluted shares increased to 266.7 million from 265.8 million in Q2. The impact of an increase in the average share price and option exercises was partially offset by share repurchases.
On the balance sheet and cash flow, as of September, we had approximately $184 million of cash and cash equivalents and approximately $6.9 billion gross debt for a net debt position of approximately $6.7 billion. Operating cash flow for the 9 months ended September 2020 was $755.1 million. For the 9 months, we had net debt payments of $330.3 million compared to $629.1 million in 2019. Treasury stock buybacks totaled $219.8 million for purchases of 3.6 million shares at an average price of $61.07 per share compared to treasury stock buybacks of $60.3 million for 1.3 million shares in 2019. The 9 months, we declared and paid $99.9 million of common stock dividends as compared to $76 million in the same period last year, an increase of 31.4%. Year-to-date, we paid interest of $212.7 million compared to $294.6 million last year due to lower debt levels and lower average interest rates.
In the 9 months, we paid income taxes of $182.5 million compared to $180.3 million in the same period of 2019. Our accounts receivable DSO improved in the quarter, to 50.4 days compared to 53.3 days as of June 2020. Capital expenditures and capitalized software totaled $80 million or 2.3% of adjusted revenue compared to $99.1 million or 2.9% of adjusted revenue in the prior year. Spending was predominantly for capitalized software, IT infrastructure, and leasehold of -- facilities leasehold improvements.
Option exercises increased this year to $129.6 million for proceeds and 4.2 million shares compared to $74.5 million of proceeds and 2.7 million shares last year. On an LTM consolidated basis EBITDA, which is used for our covenant compliance, was $1.876 billion as of September and includes $8 million of acquired EBITDA and cost savings related to our acquisition. Based on net debt of approximately $6.7 billion, our total leverage ratio was 3.58x, and our secured ratio was 2.52x.
On outlook for the year, we got basically these assumptions included -- assumed in our outlook. We assume that markets continue to be volatile, large-scale outsourcing deals and license sales are impacted. AUA levels remained flat and fund launches are somewhat delayed. As we're focusing on client service, retention rates will continue to be in the range of our most recent results.
Foreign currency exchange will be at current levels. Adjusted organic growth -- revenue growth for the year will be in the range of negative 1% to negative 2%. Interest rates on our term loan facility will approximately be 1-month LIBOR plus the spread, which is currently at 175 bps. We will manage our expenses during this period by controlling variable expenses and staff hire but we'll continue to invest in our business for the long term with capital expenditures of approximately 2.4% of revenue and R&D expenditures of approximately $400 million on a GAAP basis. We expect the tax rate to approximately be 26% on an adjusted basis.
The first scenario assumes that the economic conditions start to improve in the fourth quarter of 2020. Under these assumptions, we expect approximately the following results: Adjusted revenue of $4.650 billion, adjusted net income of $1.130 billion; diluted shares of 267 million and operating cash flow of $1.130 billion.
The second scenario assume that the economic conditions continue the same as current conditions. And in this assumption, we expect the following results: adjusted revenue of $4.625 million; adjusted net income of $1.120 billion, diluted shares of 266.3 million, and operating cash flow of $1.115 billion. The third assumption assumes that economic conditions don't start improving until later in 2021.
Under this assumption, we expect possibly the following results: Adjusted revenue of $4.600 billion; adjusted net income of $1.110 billion, diluted shares of 265.5 million and operating cash flow of $1.100 billion.
And now I'll turn it back over to Bill for final comments.
