EBITDA

I. Formal Definition

Earnings before interest, taxes, depreciation, and amortization, a non-GAAP profitability measure that approximates cash earnings from operations. EBITDA is widely used in private market valuation and in covenant compliance, but is not a substitute for GAAP operating income. The federation requires EBITDA to be reported with a clear reconciliation to GAAP net income, with adjustments to a federation-recognised standard rather than to a custom adjusted EBITDA frame under UFMS-001:3.2. Aggressive add-backs are challengeable under the conduct rules.

II. Etymology

A leveraged buyout era acronym of the 1980s; the construction was popularised by John Malone's cable television deal-making and entered general corporate vocabulary thereafter.

III. Federation Usage

Federation members publish EBITDA with reconciliation to GAAP net income. Federation-recognised adjustments are limited to interest, tax, depreciation, and amortization. Custom add-backs are footnoted with quantification and may be challenged under TGS-002:2.3.
