*Non-GAAP Financial Measures

In addition to disclosing financial results prepared in accordance with Generally Accepted Accounting Principles (GAAP), we also disclose free cash flow and earnings before interest, taxes, depreciation and amortization (EBITDA), which are non-GAAP measures.

These measures are provided because we understand that certain investors use this information when analyzing the financial position of companies in the solid waste industry, including us. Historically, these measures have been key in comparing operating efficiency of publicly traded companies in the solid waste industry, and assist investors in measuring our ability to meet capital expenditure and working capital requirements. For these reasons we utilize these non- GAAP metrics to measure our performance at all levels. These measures do not represent, and should not be considered as alternatives to cash provided by operating activities as determined in accordance with GAAP. Moreover, these measures do not necessarily indicate whether cash flow will be sufficient for such items as working capital or capital expenditures, or to react to changes in our industry or to the economy generally. Because these measures are not calculated by all companies in the same fashion, they may not be comparable to similarly titled measures reported by other companies.
