The following information relates to Company ZZA's current capital structure: Company ZZA is considering a...

Given current structure: D:E = 25:75, tax = 25%, asset beta ≈ 1.01.

Re-gear beta for new structure D:E = 35:65

βe′=βa[1+(1−T)DE]=1.01[1+0.75×3565]≈1.01×1.404≈1.42\beta_e' = \beta_a \big[1 + (1 - T)\frac{D}{E}\big] = 1.01 \big[1 + 0.75 \times \frac{35}{65}\big] \approx 1.01 \times 1.404 \approx 1.42βe′​=βa​[1+(1−T)ED​]=1.01[1+0.75×6535​]≈1.01×1.404≈1.42

Use CAPM with rf=4%r_f = 4\%rf​=4%, rm=12%r_m = 12\%rm​=12%:

ke′=rf+βe′(rm−rf)=4%+1.42×8%≈4%+11.4%≈15.4%k_e' = r_f + \beta_e'(r_m - r_f) = 4\% + 1.42 \times 8\% \approx 4\% + 11.4\% \approx 15.4\%ke′​=rf​+βe′​(rm​−rf​)=4%+1.42×8%≈4%+11.4%≈15.4%

Closest option: 15.36% → B.
