Thank you, Joe, and good morning, everyone. First, I will go over the results for the first quarter and then review our revenue and earnings guidance for the second quarter that we provided in the press release issued last evening.
Revenue in the first quarter was $127 million, up 4% versus the prior year and 2% sequentially. Our Nurse and Allied Staffing segment revenue grew by 4% year-over-year, partly as a result of one more billing day. Our Clinical Trial Services and retained search businesses also contributed to the year-over-year revenue growth.
The sequential revenue growth was driven by the improved performance of our physician staffing, Clinical Trial Services and retained service businesses, partly offset by a 1% revenue decline in our Nurse and Allied Staffing segment attributable to one less billing day than in the prior quarter.
Our gross profit margin was 26.5%, down 50 basis points from the prior year and 120 basis points sequentially. The year-over-year margin decrease was due to a combination of higher payroll taxes and higher compensation expenses partially offset by a greater contribution from our retained search business, which has the highest gross profit margin among all of our businesses. The sequential margin decrease is due primarily to the reset of payroll taxes and higher professional liability expenses stemming from a favorable accrual adjustment in the fourth quarter of 2011.
SG&A for the quarter was $31.1 million, which includes approximately $400,000 of sales and other non-income tax adjustments relating to prior year amount, as well as approximately $600,000 in equity-based compensation expenses. Excluding the non-income tax adjustments relating to prior periods, the SG&A expense as a percentage of revenue was up 60 basis points, reflecting investments we have made during 2011 in our MSP delivery infrastructure. On a sequential basis, SG&A as a percentage of revenue increased by 120 basis points due to higher compensation and payroll tax expenses.
Adjusted EBITDA, as defined in our press release, was $3 million or 2.4% of revenue. Interest expense of approximately $630,000 was down 14% from the prior year quarter and 7% sequentially. This reflects the continued de-levering of our balance sheet as well as a 25 basis point reduction in our LIBOR spread during the first quarter based on our year-end leverage ratio.
During the second quarter, we intent to amend and extend our current credit facility, which is scheduled to expire in September of 2013.
Net loss in the first quarter was $584,000 or $0.02 per diluted share, which included income and non-income tax expenses related primarily to immaterial adjustments to prior year amounts of approximately $500,000 after-tax or $0.02 per diluted share. This compares to net income of $0.01 per diluted share in the prior year quarter.
The effective income tax rate was 24.5% in the first quarter. Excluding the impact of the previously mentioned prior period tax adjustments, the effective tax rate would have been 55%, which approximates our expected tax rate for the year as a whole. The relatively high tax rate is due to certain discrete items, the impacts of which are magnified by the relatively low pre-tax book income.
Turning to the balance sheet, we ended the quarter with $39.7 million of debt and $8.9 million of cash and cash equivalents. Net of cash, our debt-to-total capital ratio was 11% and the current ratio was 2 to 1. Days sales outstanding were 53 days, unchanged from year-end, but up 3 days from the prior year. Our leverage ratio, as defined in our credit agreement, was 1.74 to 1, well below the 2.5 to 1 ratio allowed.
We generated $1.4 million of cash from operating activities in the first quarter. The excess cash supplemented with cash on the balance sheet was used to repay a net of $2.3 million of debt during the quarter and to repurchase $374,000 of our common stock at an average cost of $5.22 per share. Capital expenditures totaled approximately $0.5 million during the quarter.
Let me drill down next into our 4 reporting segments. Revenue for the Nurse and Allied Staffing segment in the first quarter was $69.5 million, up 4% versus prior year but down 1% sequentially. The year-over-year increase was due to higher staffing volume and average bill rate as well as one additional billable day. The sequential decrease was attributable to fewer hours per FTE and one less billable day that was partially offset by an increase in the average bill rate. We averaged 2,453 field FTEs in the first quarter, up 2% versus the prior year and essentially flat sequentially.
The book-to-bill ratio averaged 98% in the first quarter and averaged 99% in April, which is stronger than our typical booking patterns at that point in the quarter. As Joe indicated earlier, physician postings declined from mid-November through mid-February, which resulted in a slowdown in booking activity. Segment revenue per FTE per day in the first quarter was up 1% year-over-year, due primarily to higher average bill rates partially offset by lower average hours per FTE. The average bill rate per hour was up 3% from the prior year and 1% sequentially.
Segment contribution income as defined in our press release was $4 million in the first quarter, down 20% from the prior year and 27% sequentially. Segment contribution margin was 5.8%, down 170 basis points from the prior year and 200 basis points sequentially.
The year-over-year margin decline is due primarily to higher SG&A expenses, as Joe previously discussed. The sequential margin decline was due to a combination of the seasonal impact of the reset of payroll taxes and higher SG&A expenses.
Let me turn next to our Physician Staffing segment. Revenue was $29.3 million in the first quarter, essentially flat with the prior year but up 5% sequentially. Physician staffing days filled were essentially flat from the prior year and up 2% sequentially. Demand for temporary physician services has stabilized and we expect a modest year-over-year increase in revenue in the second quarter.
Segment contribution income for the first quarter was $2.4 million, representing an 8.2% contribution margin, down 120 basis points from the prior year and 150 basis points sequentially. The year-over-year margin decline is due primarily to higher physician compensation. The sequential decline resulted from a combination of factors in the fourth quarter of 2011 that included a favorable professional liability accrual adjustment partially offset by an accrual for state non-income based taxes related to prior years.
Revenue in our Clinical Trial Services segment in the first quarter was $16.9 million, up 8% from the prior year and 7% sequentially. Contract staffing and functional outsourcing accounted for 94% of the segment revenue in the first quarter. Contribution income was $1.3 million, up 2% from the prior year but down 10% sequentially and included an approximately $300,000 adjustment to revise estimates for prior period sales tax liabilities. Excluding this adjustment, segment contribution margin would have been 9.4% in the first quarter or 110 basis points higher than the prior year.
Revenue for the Other Human Capital Management Services segment in the first quarter was $11 million, up 9% from the prior year and 2% sequentially, driven by the strong performance of our retained search business, which was partially offset by lower revenue in our education and training business.
Contribution income was $1.1 million, up 185% from the prior year and 30% sequentially. The contribution margin was 10.1%, up 620 basis points from the prior year and 220 basis points sequentially reflecting the high operating leverage of our retained search business.
This brings me to our guidance for the second quarter of 2012. The following statements are based on current management expectations. Such statements are forward-looking and actual results may differ materially. These statements do not include the potential impact of any future mergers, acquisitions or other business combinations, impairment charges, evaluation allowances, debt refinancing costs and any material legal proceedings.
We project the average nurse and allied field FTE count to be in the 2,450 to 2,500 range in the second quarter. Consolidated revenue for the second quarter is expected to be in the $128 million to $130 million range.
We expect our gross profit margin to be approximately 27% and adjusted EBITDA margin to be in the 3.5% to 4% range. Net interest expense is expected to be approximately $500,000 in the second quarter. Based on these assumptions, earnings per diluted share are expected to be in the $0.01 to $0.03 range. This EPS guidance range is based on an estimated effective tax rate in the low to mid-50% range in the second quarter.
This concludes our formal comments. At this time, we will open the lines up to answer any question that you may have. Katherine?
