Note that EBIT, rather than net income, is used in the numerator. Because interest is paid
with pre-tax dollars, the firm’s ability to pay current interest is not affected by taxes.
This ratio has two shortcomings: (1) Interest is not the only fixed financial charge.
(2) EBIT does not represent all the cash flow available to service debt, especially if a firm
has high depreciation and/or amortization charges.
n To account for the deficiencies of the TIE ratio, bankers and others have developed the
EBITDA coverage ratio. It is calculated as EBITDA plus lease payments divided by the
sum of interest, principal repayments, and lease payments.
The EBITDA coverage ratio is most useful for relatively short-term lenders such as banks,
which rarely make loans (except real estate-backed loans) for longer than about five years.
Over a relatively short period, depreciation-generated funds can be used to service debt.
Over a longer time, depreciation-generated funds must be reinvested to maintain the plant
and equipment or else the company cannot remain in business.
Banks and other relatively short-term lenders focus on the EDITDA coverage ratio,
whereas long-term bondholders focus on the TIE ratio.
Profitability ratios show the combined effects of liquidity, asset management, and debt on
