Gross margin for the quarter was $180.9 million or 14.2% of sales, compared with $182.4 million or 14.7% of sales in the prior-year quarter. Gross margin declined due to a lower-margin mix, increased fuel costs and continued competitive pricing pressures in office products-related categories. Higher inflation during the first quarter of 2012 partially offset these negative margin affects.

First quarter 2012 operating expenses were $149.3 million, or 11.7% of sales. This includes a charge of $6.2 million for facility closures and severance costs. Excluding this item, first quarter 2012 adjusted operating expenses were $143.1 million⁽¹⁾ or 11.3%⁽¹⁾ of sales, compared with last year’s adjusted $140.7 million⁽¹⁾ or 11.4%⁽¹⁾ of sales. Adjusted operating expenses for 2011 exclude a $1.6 million asset impairment charge related to an equity investment in a managed print services business. Operating expenses reflected continued investments in the company’s strategic growth initiatives offset by savings from “War on Waste” initiatives.

Operating income for the first quarter of 2012 was $31.6 million or 2.5% of sales, versus $40.0 million or 3.2% of sales, in the first quarter of 2011. Excluding the charges noted above, first quarter 2012 adjusted operating income was $37.8 million⁽¹⁾ or 3.0%⁽¹⁾ of sales, compared with $41.6 million⁽¹⁾ or 3.4%⁽¹⁾ of sales in the prior-year quarter.

Cash Flow, Debt Trends and Share Repurchases

Net cash provided by operating activities for the first three months of 2012 was $27.9 million. Operating cash flow benefited from lower working capital requirements. Cash flow used in investing activities totaled $4.4 million in the latest quarter, compared with $9.8 million in the same period last year. Capital spending for 2012 is expected to be in the $30-35 million range.

The company has approximately $935 million of total committed debt capacity at March 31, 2012 and has maintained debt-to-EBITDA leverage at the low end of targeted levels. Outstanding debt at March 31, 2012 and 2011 was $512.2 million and $441.8 million, respectively. Debt-to-total capitalization at March 31, 2012 was 42.9%, compared with 36.5% at March 31, 2011. During the first quarter of 2012, the company paid $33.6 million to repurchase 1.1 million shares and paid $5.4 million in cash dividends. The amount remaining under Board share repurchase authorizations at April 20, 2012 was approximately $75 million.

“Our balance sheet, liquidity, and access to capital remains strong,” said Phipps. “We will maintain our capital deployment approach of prudent investments in growth and productivity, targeted acquisitions, and returning capital to shareholders through dividends and share repurchases.”

Outlook

“Our growth businesses will drive solid results given the momentum we have and the investments we are making,” continued Phipps. “Weak demand and margin pressure will continue to be factors in office products, which we are addressing with customer, network optimization, and efficiency initiatives. These actions reflect the commitment we have to our “Winning from the Middle” strategy and our confidence in the value-creating potential we have in our business.”
