So what

Within Office Depot's top line, product sales fell 1% to $2.25 billion, while services revenue climbed 34% thanks to a combination of growth from the company's business services division and the partial inclusion of CompuCom divisional results in the segment. Excluding CompuCom, service revenue climbed 19%.

"In the pivotal year of our transformation, we achieved our key priorities of recapturing top-line growth, expanding our distribution platform, growing our services business, generating significant free cash flow, and strengthening our balance sheet," stated Office Depot CEO Gerry Smith.
