Net sales for the quarter ended June 30, 2008 in the U.S. segment increased 23% as a result of market acceptance of new anti-microbial school scissors, rulers, and math kits and iPoint pencil sharpeners. Net sales for the six months ended June 30, 2008 in the U.S. segment increased 21%. Net sales in Canada in the first six months of 2008 increased by 5% in U.S. dollars but declined 6% in local currency due to soft demand in the overall office products market. European net sales in the first six months of 2008 increased 18% in U.S. dollars and 3% in local currency.

Gross margins were 39.3% in the second quarter of 2008 versus 42.0% in the comparable period last year. For the first six months of 2008, gross margins were 40.3% compared to 42.6% in the same period in 2007. The gross margin declines were due to increased costs of material, labor, and energy, and the appreciation of the Chinese currency against the U.S. dollar. Also, in the second quarter of 2008, the company gained market share in the highly competitive back to school segment which reduced gross margins.

Walter C. Johnsen, Chairman and CEO, said, "The second quarter and year to date sales demonstrate the strength of our new products, and the values they deliver to our customers. Acme's base of business has broadened during the past several years, with growth in the mass market, office superstores, independent dealers, and hardware and industrial markets. Our international sales base has also grown. The broadening of our customer base and international sales has offset weakness in some domestic accounts."

The Company's bank debt less cash on June 30, 2008 was $11.3 million compared to $9.6 million on June 30, 2007. The increase in bank debt during the twelve month period was primarily due to an increase in borrowings for inventory and accounts receivables for the back to school season as well as share repurchases, partially offset by earnings. Based on anticipated cash flow, the debt level is expected to decline during the second half of the year. During the 12 month period ended June 30, 2008, Acme purchased 67,600 shares of its common stock for approximately $900,000 under its previously announced repurchase program. As of June 30, 2008, there were 182,400 shares that may be purchased under the outstanding stock repurchase programs.
