Non-GAAP Financial Measures [Abstract]

Non-GAAP Financial Measures

Non-GAAP Financial Measures

We use operating cash flow (“OCF”), a non-GAAP financial measure, as a key element in determining performance for purposes of incentive compensation under our annual STIP. OCF is defined as earnings before interest, taxes, depreciation, amortization, accretion and impairment (“EBITDA”) less purchases of property and equipment (EBITDA is defined as operating income plus depreciation, amortization, accretion and impairment, each determined in accordance with GAAP). Purchases of property and equipment are also determined in accordance with GAAP.

Below is a reconciliation of our non-GAAP measure for the periods stated:
