Revenue represents business unit sales or total Company net trade sales to third parties. • Working Capital as a Percentage of Sales. Working Capital as a Percentage of Sales is calculated by taking the average 13 months of business segment or total Company working capital divided by the sum of 12 months of 2016 business segment sales or total Company sales (where applicable), where working capital equals (1) trade accounts receivable (2) plus inventory (3) minus trade accounts payable. Progress against the Working Capital as a Percentage of Sales metric is reflected by lower levels of working capital, so results that are less than target are viewed as exceeding target performance.
