Callaway Golf Company (“Callaway”) conducted a good faith, reasonable country of origin inquiry with respect to columbite-tantalite (coltan), cassiterite, gold, wolframite and their derivatives, which are limited to tantalum, tin, and tungsten (“Conflict Minerals”), that may be considered necessary to the functionality or production of products that Callaway manufactures or contracts to manufacture for the 2015 reporting period (the “Covered Conflict Minerals”). Callaway’s inquiry, as described below, was reasonably designed to determine whether the Covered Conflict Minerals originated in the Democratic Republic of the Congo or an adjoining country (the “Covered Countries”), or are from recycled or scrap sources. Based on the results of that inquiry, Callaway has no reason to believe that the Covered Conflict Minerals described in this Form SD originated in the Covered Countries. Therefore, Callaway is not required to provide a Conflict Minerals Report with respect to the Covered Conflict Minerals.
