Answer and Explanation:
The computation is shown below:
a) Liabilities to equity ratio is
= $200 ÷ ($500 - $200)
= 0.667
Times interest earned ratio is
= EBIT ÷ Interest expense
= $120 ÷ $28
= 4.285
Times burden covered is
= EBIT ÷ (Interest +Principal repayment ÷ ( 1 -tax rate))
= 120 ÷ (28+24 ÷ (1-0.4))
= 1.764
b)
Interest paying requirements
= ($128 - $20) ÷ 120
= 76.7%
Principal and interest requirements
= [$120 - ($28 + $24 ÷ (1-0.4))] ÷ 120
= 0.433 or 43.3%
Principal, Interest and Common dividend payments -
= [$120 - ($28 + (($24 + 0.3 × 20) ÷ (1 - 0.4))] ÷ 120
= 0.35 or 35%
