Debt Service Coverage Ratio

Financial institutions, which provide the bulk of long-term finance for industrial projects,

evaluate the financial viability of a project primarily in terms of the internal rate of

return and the debt service coverage ratio.

DSCR

Debt service coverage ratio (DSCR) is defined as

where PATi = Profit after tax for year i

Di = depreciation for year i

Ii = interest on long-term loans of financial

institutions for year i

LRIi = loan repayment instalment for year i.

n = period over which the loan has be repaid.

Looking at the debt service coverage ratio we find the numerator consists of a mixture

of post-tax and pre-tax figures (profit after tax is a post tax figure and interest is a pre-

tax figure). Likewise, the denominator consists of mixture of post-tax and pre-tax figures

(loan repayment installation is a post-tax figure and interest is a pre-tax figure). It is

difficult to interpret a ratio which is based on a mixture of post-tax and pre-tax figures.

In view of this difficulty, we suggest two alternatives :

Alternative 1:

Earnings before depreciation interest and taxes

DSCR = ----------------------------------------------------------

Interest + Loan repayment instalment

---------------------------------------------

1 - Tax rate

Alternative 2:

Profit after tax + Depreciation

DSCR = --------------------------------------

Loan repayment instalment

While alternative 1 is based on pre-tax figures, alternative 2 is based on post-tax figures.
