Answer: See explanation
Step-by-step explanation:
The flotation cost adjustment that must be added to its cost of retained earnings will be calculated thus:
= Expected dividend / [Current price × (1 - Floatation cost)] + Expected growth rate
= 2.00/[20.00 × (1 - 4.5%)] + 4.2%
= 2.00 /[20.00 × (1 - 0.045)] + 0.042
= 2.00 / (20.00 × 0.955) + 0.042
= (2.00/19.10) + 0.042
= 0.104712 + 0.042
= 0.146712
New cost of equity = 14.67%
You didn't give the cost of equity calculated without the flotation adjustment. Let's assume that this is maybe 11%, the floatation on adjustment factor = 14.67% - 11% = 3.67%
