United Stationers Inc. provided a reconciliation of non-GAAP financial measures for adjusted operating income and earnings per share for Q1 2007 compared to Q1 2006. Sales increased slightly from $1.148 billion to $1.193 billion. Gross profit and adjusted gross profit both increased slightly year-over-year as a percentage of sales. Operating expenses decreased as a percentage of sales due to one-time write-offs and restructuring charges in 2006. Adjusted operating income and earnings per share increased in 2007 compared to 2006 due to the one-time charges excluded from the non-GAAP measures.
