计算residual income时的equity 和net income

NO.PZ2023032701000063 问题如下 Ramcollects aitionta for valuing PBRI using the multistage RI mol. For this mol, he assumes annugrowth rate of resiincome of 15% ring the forecast horizon of 5 years (Years 1 to 5) anscounts the terminyear’s resiincome a perpetuity. Other inputs are founin Exhibit 3.Exhibit 3 ta for ResiIncome MolUsing the ta in Exhibit 3, Raman's estimate of the contribution ththe terminvalue of the resiincome strein 5 years will contribute to the current value of equity is closest to: A.$42.25 B.$61.91 C.$48.82 Using a multi-stage resiincome mol anthe ta in Exhibit 3:Equity charge = Equity capit× Cost of equity capital= 20.97 × 0.124 = $2.60 millionResiincome of the more recent ye= Net income – Equity charge= 8.00 – 2.60 = $5.40 millionRaman’s assumegrowth rate ring the forecast perioof five years = 15%Annuresiincome ring the no growth perio(after Ye5) = 5.40 × (1.15)5 = $10.86 millionPresent value (PV) of the resiincome from perpetuperio T = 5 = ($10.86/0.124)=$87.58 millionPV of the perpetuperioresiincome T0= 87.58/(1.124)5=$48.82 million 没太理解这道题的意思，老师麻烦可以帮忙详细下这道题吗？辛苦啦
