Thank you, Henrik. Good morning, everyone. Turning to our first quarter of fiscal 2012 results on Slide 4. As Henrik mentioned, revenues for the first quarter were $1.07 billion, up 4.3% from the prior year, primarily related to revenue associated with the acquisition of The Linc Group, which occurred on December 1, 2010. The period-over-period increase in revenues attributable to Linc was approximately $36 million.
Gross margins for the 2012 first quarter were 10%, a decrease of 20 basis points from 10.2% in the prior-year period. The year-over-year decrease in gross margin is largely the result of lower profits in Facility Solutions due to the mix and timing of government projects. Gross margin was also impacted by higher payroll taxes, primarily in the Janitorial and Security segments, partially offset by sustained improvements in historical credits on client receivables.
Our SG&A expense for the first quarter increased $1.4 million to $84 million. The year-over-year increase is primarily the result of expenses associated with the Linc acquisition. Amortization of intangible assets for the first quarter increased $0.2 million to $5.5 million, primarily related to the amortization of intangible assets from the Linc acquisition. Depreciation for the first quarter was $7.4 million, flat compared to the year-ago period.
Interest expense decreased $1.2 million to $2.8 million from $4 million in the 2011 first quarter. The decrease was primarily related to lower average borrowings and average interest rates under the line of credit. The average outstanding balance under the company's line of credit was $312.1 million during the quarter compared to an average balance of $337 million in the prior year ago quarter due to the acquisition of Linc on December 1, 2010. Our effective tax rate on income from continuing operations for the quarter -- for the first quarter of 2012 was 41.2% compared to 38.5% in the prior-year period. This increase is primarily the result of the reduced availability of employment-based credits compared to the year-ago period. Specifically, Congress did not extend the federal empowerment zone and Work Opportunity Tax Credit, both of which expired on December 31.
In addition, fiscal 2011 benefited from greater tax credits associated with the hire act that was in place for calendar 2011. As a result, we anticipate our effective tax rate for fiscal 2012 to be in the range of 39% to 42%.
For 2012, we continue to expect the cash tax rate of 20% to 23% as the effects of OneSource NOLs diminish. Adjusted income from continuing operations for the first quarter was $11.8 million or $0.22 per diluted share. This compared to $11.7 million or $0.22 per diluted share in the same period last year. Adjusted EBITDA, which excludes items impacting comparability, was $35.9 million for the 2012 first quarter, essentially flat when compared to $35.7 million in the prior year period. The benefit from improvements in historical credits and client receivables and new business were offset by residual price compression through third quarter of 2011, higher payroll-related expenses and lower-margin contributions from Facility Solutions.
Now turning to Slide 5. We ended the quarter with $295.2 million in working capital, an increase of $4.6 million from the $290.6 million at October 31, 2011. The increase in working capital was primarily driven by the timing of collections received from clients, partially offset by the paydown of a portion of the outstanding borrowings on the credit facility. Net trade accounts receivable at quarter end were $573.8 million versus $552.1 million at October 31, 2011. Days sales outstanding at quarter end were 50 days, up 2 on a sequential basis and down 1 compared to the first quarter of 2011. The year-over-year decrease in DSO is attributable to our continued focus on receivables, as well as improvements in our end-to-end processes. Cash provided from continuing operating activities was $11.8 million for the first quarter compared to $0.3 million in the comparable prior year period. The increase of $11.5 million was primarily related to the timing of collections received from clients. Total insurance claim liabilities at January 31, 2012, were $344.9 million compared to $341.4 million at the end of fiscal 2011. Self-insurance claims paid during the quarter totaled $20.9 million compared to $20.3 million in the first quarter of 2011. I would now like to turn the call back to Henrik, who will provide his perspective on the first quarter operational performance.
