Sales and segment income of our metal container business and part of our closures business are dependent, in part, upon fruit and vegetable harvests. The size and quality of these harvests varies from year to year, depending in large part upon the weather conditions in applicable regions. Because of the seasonality of the harvests, we have historically experienced higher unit sales volume in the third quarter of our fiscal year and generated a disproportionate amount of our annual segment income during that quarter.
