Thank you, Bob. Our first quarter performance is recapped on Slide 4. Sales declined 3%, foreign exchange translation was modestly negative, while pricing was favorable 1%. Underlying volumes declined 4% due to declines mainly in Europe, but also in Canada.
Our gross profit margin declined 90 basis points to 29%, as shown on Slide 5. The decline was due to higher commodity cost relative to selling prices, which had a 90-basis-point impact. Sales mix, which had a 50-basis-point impact, and other items largely deleveraging the fixed cost, which was 40 basis points. These factors were partially offset by the favorable impact of cost reductions, such as improvements in freight and distribution costs, which accounted for 90 basis points.
SG&A expenses decreased 50 basis points, primarily due to other costs in Europe.
In all, operating income margin decreased 40 basis points to 4.1% from 4.5%. Foreign exchange was a slight negative to the bottom line, but not material.
Turning to an overview of our segments. During the quarter, reported sales for the Americas increased slightly, driven by higher selling prices. Volume declined in the quarter due to lower sales in Canada, primarily at one customer that reduced inventory. Largely as a result of adverse product mix as well as high commodity costs in Canada, operating margins in the Americas decreased 180 basis points to 1.8%. Keep in mind that Q1 is our seasonally low-margin quarter.
International segment sales declined 10%, driven by volume declines of 13%. Selling prices were higher by 3%. The decline in volume was due entirely to Europe and was largely in line with our expectations. The economy there is softer than expected, and as we announced when we reported Q4 results, we've taken even further actions to reduce costs as a result of the environment there. We did see profits improve in our International segment. Margins improved to 8.5% from 3.9%, but last year, we did have $3.9 million of costs related to our operational changes in Europe.
Computer Product sales increased 1%. Volume increased 5%, but was offset by pricing and currency. The volume increase was the result of strong sales of new products for iPads and iPhones. Computer Products operating profit decreased in the quarter due to product mix, with lower laptop security product sales. The margin decreased to 18% from 22.5% in the prior year quarter. We expect this adverse margin mix to continue.
In terms of the balance sheet and cash flow, as you know, we did complete our refinancing at the end of April. So our balance sheet in Q1 is not reflective of our ongoing profile.
Some important points to note are that ACCO Brands has its normal seasonal cash outflow in Q1 and we typically generate all of our cash in Q4. Mead Consumer & Office Products generates the majority of its cash in Q1, so that stayed at Mead's former parent this year. But by this time next year, we will benefit from having the combined companies' cash flow and therefore, expect our net leverage to be under 3x.
Q2 should be a cash outflow quarter for the combined business, and Q3 should be a cash-neutral quarter for us. The transaction with Mead doubles our EBITDA, but it triples our annual free cash flow. This is as a result of more favorable interest rates and low cash taxes. Therefore, next year we expect to generate combined free cash flow of at least $150 million.
We had already provided combined guidance when we pre-released in April, and that remains intact. Both ACCO and Mead generate the majority of profits in Q3 and Q4, and that seasonal pattern will continue but will be more pronounced with the combined company.
We will provide historical pro forma combined financial results by quarter and by segment before our next quarter end.
At this point, we will conclude our prepared remarks and Bob and I will be happy take your questions. Operator?
