("GOBA"), a leading provider of school and craft products in Mexico under the Barrilito^®brand, for a preliminary purchase price of approximately $37.2 million, net of cash acquired, and subject to working capital and other adjustments. The GOBA Acquisition has increased the breadth and depth of our distribution, especially with wholesalers and retailers throughout Mexico, and complements our existing office products portfolio with a strong offering of school and craft products.
