Determining PB Ratio for Companies with Different Returns and Growth
Assume that the present value of expected ROPI follows a perpetuity with growth g (Value = Amount/ [r - g]). Determine the theoretically correct PB ratio for each of the following companies A and B.

Answer |
Solution :
ROPI for company A = $100 ( 18% - 10%) = $8
ROPI for company B = $100 * (11% - 10%) = $1
Growth rate of ROPI for company A = 2%
Growth rate of ROPI for company B= 4%
Present value of ROPI for company A = [$8 / 1.10] + [$8 * (1.02) / (1.10)^2] + [ [$8 * (1.02)^2 / (1.10)^3]...............upto infinity terms
This is sum of infinity terms of GP, therefore
a (first term) = $8 / 1.10
r (Common ratio) = 1.02 / 1.10
Sum of infinity terms of GP = a / (1-r)
= ($8 / 1.10) / [1 - (1.02/1.10)] = $100
Therefore market value of equity for Company A = $100 + $100 = $200
Present value of ROPI for company B = [$1 / 1.10] + [$8 * (1.04) / (1.10)^2] + [ [$8 * (1.04)^2 / (1.10)^3]...............upto infinity terms
This is sum of infinity terms of GP, therefore
a (first term) = $1 / 1.10
r (Common ratio) = 1.04 / 1.10
Sum of infinity terms of GP = a / (1-r)
= ($1 / 1.10) / [1 - (1.04/1.10)] = $16.67
Market value of equity for company B = $100 + $16.67 = $116.67
PB ratio - Company A = Market value / Book value = $200 / $100 = 2
Company B = $116.67 / $100 = 1.17
