Free Cash Flow

We define free cash flow as net cash provided by operating activities, as defined under US GAAP, less capital expenditures. We believe that free cash flow is an important measure of our liquidity and therefore our ability to reduce debt and make strategic investments after considering the capital expenditures necessary to operate the business. We use free cash flow in the evaluation of the Company’s business performance. However, a limitation of this measure is that it does not reflect payments made in connection with investments and acquisitions, which reduce liquidity. To compensate for this limitation, management evaluates its investments and acquisitions through other return on capital measures.

Daily Sales Calculations

(1) Average daily sales are defined as sales for a period of time divided by the number of shipping days in that period of time.

(2) Average organic daily sales are defined as sales for a period of time divided by the number of shipping days in that period of time excluding any sales from acquisitions made subsequent to the beginning of the prior year period.

Average organic daily sales is presented herein because we believe it to be relevant and useful information to our investors since it is used by management to evaluate the operating performance of our business, as adjusted to exclude the impact of acquisitions, and compare our organic operating performance with that of our competitors. However, average organic daily sales is not a measure of financial performance under US GAAP and it should be considered in addition to, but not as a substitute for, other measures of financial performance reported in accordance with US GAAP, such as net sales. Management utilizes average organic daily sales as an operating performance measure in conjunction with US GAAP measures such as net sales.

Adjusted EBITDA

Adjusted EBITDA differs from Consolidated EBITDA per our credit facility agreement for purposes of determining our net leverage ratio. We define Adjusted EBITDA as net income plus interest expense (income), net, (gain) loss on extinguishment of debt, net, income taxes and depreciation and amortization. Adjusted EBITDA is presented herein because we believe it to be relevant and useful information to our investors since it is consistently used by our management to evaluate the operating performance of our business and to compare our operating performance with that of our competitors. Management also uses Adjusted EBITDA for planning purposes, including the preparation of annual operating budgets, and to determine appropriate levels of operating and capital investments. Adjusted EBITDA excludes certain items, which we believe are not indicative of our core operating results. We therefore utilize Adjusted EBITDA as a useful alternative to net income as an indicator of our operating performance compared to the Company’s plan. However, Adjusted EBITDA is not a measure of financial performance under US GAAP. Accordingly, Adjusted EBITDA should not be used in isolation or as a substitute for other measures of financial performance reported in accordance with US GAAP, such as gross margin, operating income, net income, cash flows from operating, investing and financing activities or other income or cash flow statement data prepared in accordance with US GAAP. While we believe that some of the items excluded from Adjusted EBITDA are not indicative of our core operating results, these items do impact our income statement, and management therefore utilizes Adjusted EBITDA as an operating income, performance measure in conjunction with US GAAP measures, such as gross margin, operating income, net income, cash flows from operating, investing and financing activities or other income or cash flow statement data prepared in accordance with US GAAP. We define Adjusted EBITDA margin as Adjusted EBITDA divided by net sales.
