Executive Vice President and Chief Financial Officer at Robert Half
Thank you, Keith, and hello, everyone.
As Keith noted, global revenues were $1.564 billion in the third quarter. On an as-adjusted basis, third quarter talent solutions revenues were down 17% year-over-year. US talent solutions revenues were $823 million, down 20% from the prior year's third quarter. Non-US talent solutions revenues were $260 million, down 7% year-over-year on an as-adjusted basis. We have 319 talent solutions locations worldwide, including 89 locations in 18 countries outside of the United States.
In the third quarter, there were 63.1 billing days compared to 64.3 billing days in the same quarter one year ago. The fourth quarter of 2023 has 61.1 billing days compared to 61.2 billing days during the fourth quarter of 2022. Currency exchange rate movements during the third quarter had the effect of increasing reported year-over-year total revenues by $13 million; $10 million for talent solutions and $3 million for Protiviti. Contract talent solutions bill rates for the third quarter increased 4.6% compared to one year ago, adjusted for changes in the mix of revenues by functional specialization, currency and country. This rate for the second quarter was 6%.
Now, let's take a closer look at results for Protiviti. Global revenues in the third quarter were $481 million. $386 million of that is from business within the United States, and $95 million is from operations outside the United States. On an as-adjusted basis, global third quarter Protiviti revenues were down 5% versus the year ago period. US Protiviti revenues were down 6%, while non-US Protiviti revenues were down 2%. Protiviti and its independently-owned member firms serve clients through a network of 89 locations in 29 countries.
Turning now to gross margin. In contract talent solutions, third quarter gross margin was 39.8% of applicable revenues versus 39.4% in the third quarter one year ago. Conversion revenues, or contract to hire, were 3.5% of revenues in the third -- in the quarter compared to 4.1% of revenues in the quarter one year ago. Our permanent placement revenues in the third quarter were 12.9% of consolidated talent solutions revenues versus 13.8% in the same quarter one year ago. When combined with contract talent solutions gross margin, overall gross margin for talent solutions was 47.5% compared to 47.8% of applicable revenues in the third quarter last year. For Protiviti, gross margin was 26.2% of Protiviti revenues compared to 30.5% of Protiviti revenues one year ago. Adjusted for deferred compensation-related classification impacts, gross margin for Protiviti was 25.6% for the quarter just ended compared to 30% last year.
Moving on to SG&A. Enterprise SG&A costs were 31.8% of global revenues in the third quarter compared to 29.9% in the quarter one year ago. Adjusted for deferred compensation-related classification impacts, enterprise SG&A costs were 32.5% for the quarter just ended compared to 30.6% last year. Talent solutions SG&A costs were 39.3% of talent solutions revenues in the third quarter versus 35.3% in the third quarter of 2022. Adjusted for deferred compensation-related classification impacts, talent solutions' SG&A costs were 40.4% for the quarter just ended compared to 36.3% last year. The lower mix of permanent placement revenues this quarter versus one year ago had the effect of decreasing the quarter's adjusted SG&A ratio by 0.5 percentage points. Third quarter SG&A costs for Protiviti were 14.7% of Protiviti revenues compared to 16% of revenues last year.
Operating income for the quarter was $144 million. Adjusted for deferred compensation-related classification impacts, combined segment income was $130 million in the third quarter. Combined segment margin was 8.3%. Third quarter segment income from our talent solutions divisions was $78 million, with a segment margin of 7.2%. Segment income for Protiviti in the third quarter was $52 million, with a segment margin of 10.9%.
Our third quarter tax rate was 30%, up from 20% -- 26% for the same quarter one year ago. The higher tax rate for 2023 can be attributed to an increased impact from nondeductible expenses and fewer tax credits. At the end of the third quarter, accounts receivable were $941 million, and implied days sales outstanding, or DSO, was 54.2 days.
Before we move to fourth quarter guidance, let's review some of the monthly revenue trends we saw in the third quarter and so far in October, all adjusted for currency and billing days. Contract talent solutions exited the third quarter with September revenues down 17% versus the prior year compared to a 16% decrease for the full quarter. Revenues for the first two weeks of October were down 17% compared to the same period last year. On a week-on-week sequential basis, the rates of decline have narrowed over the past 10 to 12 weeks.
Permanent placement revenues in September were down 26% versus September 2022. This compares to a 23% decrease for the full quarter. For the first three weeks of October, permanent placement revenues were down 24% compared to the same period in 2022. We provide this information so that you have insight into some of the trends we saw during the third quarter and into October. But as you know, these are very brief time periods. We caution against reading too much into them.
With that in mind, we offer the following fourth quarter guidance. Revenues, $1.415 billion to $1.515 billion; income per share, $0.75 to $0.89. Midpoint revenues of $1.465 billion or [Phonetic] 15% lower than the same period in 2022 on an as-adjusted basis. The major financial assumptions underlying the midpoint of these estimates are as follows. The revenue growth year-over-year as-adjusted talent solutions, down 15% to 20%; Protiviti, down 8% to 10%; overall, down 13% to 18%. Gross margin percentage for contract talent, 39% to 41%; Protiviti, 25% to 27%; overall, 39% to 41%.
For SG&A as a percentage of revenues, excluding deferred compensation classification impacts for talent solutions, 39% to 41%; Protiviti, 15% to 17%; overall, 32% to 34%. And for segment income, talent solutions, 5% to 8%; Protiviti, 9% to 12%; and overall, 6% to 9%. Tax rate, 27% to 28%. Shares, 104.5 million to 105.5 million. 2023 capital expenditures and capitalized cloud computing costs, $80 million to $90 million, with $20 million to $25 million in the fourth quarter. We limit our guidance to one quarter. All estimates we provide on this call are subjects to the -- are subject to the risks mentioned in today's press release and in our SEC filings.
Now, I'll turn the call back over to Keith.
