Executive Vice President, Chief Financial Officer at Robert Half
Thank you, Keith, and hello, everyone. As Keith noted, global revenues were $1.465 billion in the third quarter. On an as-adjusted basis, third quarter talent solutions revenues were down 13% year-over-year. U.S. talent solutions revenues were $725 million, down 13% from the prior year's third quarter. Non-U.S. talent solutions revenues were $229 million, also down 13% year-over-year. We conduct talent solutions operations through offices in the United States and 17 other countries. In the third quarter, there were 64.1 billing days compared to 63.1 billing days in the same quarter one year ago. The fourth quarter of 2024 has 61.6 billing days compared to 61.1 billing days during the fourth quarter of 2023. Currency exchange rate fluctuations during the third quarter had a de minimis impact on reported revenues. Contract talent solutions bill rates for the third quarter increased 3.2% 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 3.1%.
Now let's take a closer look at results for Protiviti. Global revenues in the third quarter were $511 million, $421 million of that is from the United States and $90 million is from outside of the United States. On an as-adjusted basis, global third quarter Protiviti revenues were up 5% versus the year ago period. U.S. Protiviti revenues were up 8%, while non-U.S. Protiviti revenues were down 8%. Protiviti and its independently owned member firms serve clients through locations in the United States and 29 other countries.
Turning now to gross margin. In contract talent solutions, third quarter gross margin was 38.9% of applicable revenues versus 39.8% in the third quarter one year ago. Conversion revenues or contract to hire were 3.3% of revenues in the quarter compared to 3.5% of revenues in the quarter one year ago. Our permanent placement revenues were 12.9% of consolidated talent solutions revenues in both the current quarter and the third quarter of 2023. When combined with contract talent solutions gross margin, overall gross margin for talent solutions was 46.8% compared to 47.5% of applicable revenues in the third quarter last year. For Protiviti, gross margin was 24.6% of Protiviti revenues compared to 26.2% of Protiviti revenues one year ago.
Adjusted for the amount of deferred compensation that is completely offset by investment income related to employee deferred compensation trusts or the deferred compensation investment income offset, gross margin for Protiviti was 25.8% for the quarter just ended compared to 25.6% last year. Enterprise SG&A costs were 34.9% of global revenues in the third quarter compared to 31.8% [Phonetic] in the same quarter one year ago. Adjusted for the deferred compensation investment income offset, enterprise SG&A costs were 33.3% for the quarter just ended compared to 32.5% last year. Talent solutions SG&A costs were 45.2% of talent solutions revenues in the third quarter versus 39.3% in the third quarter of 2023.
Adjusted for the deferred compensation investment income offset, talent solutions SG&A costs were 42.8% for the quarter just ended compared to 40.4% last year. Third quarter SG&A costs for Protiviti were 15.6% of Protiviti revenues compared to 14.7% of revenues for the same quarter last year. Operating income for the quarter was $61 million. Adjusted for the deferred compensation investment income offset, combined segment income was $90 million in the third quarter. Combined segment margin was 6.2%. Third quarter segment income from our talent solutions divisions was $38 million with a segment margin of 4%. Segment income for Protiviti in the third quarter was $52 million with a segment margin of 10.2%. Our third quarter 2024 income statement includes $29 million as income from investments held in employee deferred compensation plans. This is completely offset by an equal amount of additional employee deferred compensation costs, which are reflected in SG&A expenses and direct costs.
As such, it has no effect on our reported net income. Our third quarter tax rate was 31% compared to 30% one year ago. At the end of the third quarter, accounts receivable were $885 million and implied days sales outstanding or DSO was 54.4 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. Contract talent solutions exited the third quarter with September revenues down 14% versus the prior year compared to a 13% decrease for the full quarter. Revenues for the first two weeks of October were down 12% compared to the same period last year. Permanent placement revenues in September were down 7% versus September of 2023. This compares to a 13% decrease for the full quarter.
For the [Phonetic] first three weeks of October, permanent placement revenues were down 19% compared to the same period in 2023. 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 reading too much into them.
With that in mind, we offer the following fourth quarter guidance. Revenue, $1.34 billion to $1.44 billion, income per share, $0.47 to $0.61. The midpoint revenues of $1.39 billion are 7% lower than the same period in 2023 on an as-adjusted basis. The major financial assumptions underlying the midpoint of these estimates are as follows. Revenue growth on a year-over-year as-adjusted basis, talent solutions, down 9% to 13%, Protiviti, up 3% to up 6%, overall, down 4% to 8%.
Contract margin percentage for contract talent, 38% to 40%, Protiviti on an as-adjusted basis for the deferred compensation investment income offset, 25% to 27%, overall, 38% to 40%. SG&A as a percentage of revenues adjusted for the deferred compensation in this investment income offset, talent solutions, 43% to 45%, Protiviti, 14% to 16%, overall, 33% to 35%.
Segment income for talent solutions, 2% to 4%, Protiviti, 10% to 12%, overall, 4% to 6%, tax rate, 28% to 30%, shares, 102 million to 103 million. 2024 capital expenditures and capitalized cloud computing costs, $80 million to $90 million with $20 million to $25 million in the fourth quarter. All estimates we provide on this call 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.
