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.
