Michael Buckley
Chief Financial Officer at Robert Half
Thank you, Keith, and hello, everyone. As Keith noted, global revenues were $1.639 billion in the second quarter. On an as adjusted basis, second quarter Talent Solutions revenues were down 16% year-over-year. U.S. Talent Solution revenues were $885 million, down 17% from the prior year's second quarter. Non-U.S. Talent Solutions revenues $263 million, down 9% year-over-year on an as-adjusted basis. We have 318 talent locations worldwide including 87 locations and 18 countries outside of the United States.
In the second quarter, there were 63.3 billing days compared to 63.4 billing days in the same quarter, one year ago. The third quarter of 2023 has 63.1 billing days compared to 64.3 billing days during the third quarter of 2022. Currency exchange rate movements for the second quarter had the effect of decreasing reported year-over-year total revenues by $3 million. And that's $3 million for Talent Solutions and a negligible impact for Protiviti.
Contract Talent Solutions bill rates for the quarter increased 6% compared to one year ago, adjusted for changes in the mix of revenues by functional specialization, currency and country. This rate for the first quarter was 6.9%.
Now let's take a closer look at results for Protiviti. Global revenues in the second quarter were $491 million, $386 million of that is from business within the United States and $105 million is from operations outside of the United States. On an as adjusted basis, second quarter Protiviti revenues were down 1% versus the year ago period. U.S. Protiviti revenues were down 2% while non-U.S. Protiviti's revenues were up 4%. 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, second quarter gross margin was 39.9% of applicable revenues, the same as the second quarter one year ago. Conversion revenues or contract to hire were 3.7% of revenues in the quarter compared to 4.1% of revenues in the quarter one year ago. Our permanent placement revenues in the second quarter were 13% of consolidated Talent Solutions revenues versus 14.7% in the same quarter one year ago. When combined with Contract Talent Solutions gross margin, overall gross margin for Talent Solutions was 47.7% compared to 48.7% of approvable revenues in the second quarter one year ago.
For Protiviti, gross margin was 22.9% of Protiviti revenues compared to 30.4% of Protiviti revenues one year ago. Adjusted for deferred compensation-related classification impacts, gross margin for Protiviti was 24% for the quarter just ended compared to 28.1% one year ago. Second quarter Protiviti gross margin included $2.8 million of severance costs related to employee headcount reductions.
Enterprise SG&A costs were 33.1% of global revenues in the second quarter compared to 27.3% in the same quarter one year ago. Adjusted for deferred compensation related classification impacts, enterprise SG&A costs were 31.6% for the quarter just ended compared to 30.3% one year ago. Talent Solutions SG&A costs were 40.7% of Talent Solutions revenues in the second quarter versus 32.2% in the second quarter of 2022. Adjusted for deferred compensation related classification impacts, Talent Solutions SG&A costs were 38.7% for the quarter just ended compared to 36.2% one year ago. Second quarter Talent Solutions SG&A costs included $5.1 million of severance costs related to employee headcount reductions.
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 0.9 percentage points. Second quarter SG&A costs for Protiviti were 15.1% of Protiviti revenues compared to 14% of revenues in the one year ago period as operating expenditures continue to return to more normal pre-pandemic levels. Second quarter Protiviti SG&A costs also included $400,000 of severance costs related to employee head count terminations.
Operating income for the quarter was $118 million, this includes severance charges of $8 million or $0.05 per share. Adjusted for deferred compensation related classification impacts, combined segment income was $147 million in the second quarter. Combined segment margin was 8.9%. Second quarter segment income from our Talent Solutions divisions was $103 million with a segment margin of 9%. Segment income for Protiviti in the second quarter was $44 million with a segment margin of 8.9%.
Our second quarter tax rate was 30% and up from -- up from 27% for the same quarter one year ago. The higher tax rate for 2023 can be attributed to an increased impact of nondeductible expenses, fewer tax credits as well as lower stock compensation deductions. At the end of the second quarter, accounts receivable were $974 million, and implied days sales outstanding, or DSO, was 53.5 days.
Before we move on to third quarter guidance, let's review some of the monthly revenue trends we saw in the second quarter and so far in July, all adjusted for currency and billing days. Contract Talent Solutions exited the second quarter with June revenues down 15% versus the prior year compared to a 14% decrease for the full quarter. Revenues for the first two weeks of July were down 15% compared to the same period one year ago. Permanent placement revenues in June were down 26% versus June 2022, this compares to a 25% decrease for the full quarter.
For the first three weeks in July, permanent placement revenues were down 28% compared to the same period in 2022. We provide this information, so you have insight into some of the trends we saw during the second quarter and into July. 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 third quarter guidance: Revenues, $1.48 billion to $1.58 billion; income per share, $0.76 to $0.90. Midpoint revenues of our -- of $1.53 billion are 16% 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: revenue growth year-over-year as adjusted and Talent Solutions, down 17% to 22% for Protiviti, down 4% to 7% and overall, down 13% to 18%. Gross margin percentage for Contract Talent, 39% to 41%, for Protiviti, 25% to 27% and overall, 39% to 41%.
SG&A as a percentage of revenue, excluding deferred compensation classification impacts: Talent Solutions, 39% to 41%; Protiviti, 14% to 16%; overall, 32% to 34%. Segment income for Talent Solutions, 5% to 8%; productivity, 9% to 12%; overall, 6% to 9%. Our tax rate, 29% to 30% and shares 105.5 million to 106.5 million shares. 2023 capital expenditures and capitalized cloud computing costs, $70 million to $80 million with $13 million to $18 million in the third quarter. We limit our guidance to one 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.
