Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

Pool Corporation is the world's largest wholesale distributor of swimming pool supplies, equipment and related leisure products and is one of the leading distributors of irrigation and landscape products in the United States. We offer our customers approximately 200,000 manufacturer, proprietary and exclusive brand products. As a distributor, the majority of products that we sell are made to manufacturers' specifications and sold under the manufacturers' brand names. We also contract with certain vendors and manufacturers to supply or produce our branded products, which generally consists of affixing our trademark or label to a generic product. With respect to these products, we may exert varying degrees of involvement in the design process, but in most cases, we have no influence over the manufacturing process.

We conducted an extensive review of our branded products manufactured or contracted to be manufactured during the Reporting Period to determine whether any branded products contained one or more Conflict Minerals necessary to the functionality or production of the branded product. Vendors from whom we source our branded products were asked to complete our internally developed questionnaire to identify any products that may contain Conflict Minerals. We conducted a good faith reasonable country of origin inquiry, including a questionnaire that sought the name of the country of origin for any Conflict Minerals so identified.

In compiling the responses, we noted that, as in prior years, certain branded products we contracted to be manufactured in the Reporting Period contain Conflict Minerals. As described by the applicable manufacturers, these Conflict Minerals are necessary to the production of the products in order to achieve desired objectives or aesthetic finishes. For the products identified to contain Conflict Minerals, the manufacturers disclosed that the Conflict Minerals were not sourced from the Covered Countries for the Reporting Period.

Based on our vendor inquiry procedures and reasonable country of origin inquiries, we have no reason to believe that the products we contracted to be manufactured in the Reporting Period contain Conflict Minerals that may have originated in the Covered Countries.
