Krieger String & Twine expects to generate a return on equity (ROE) of 13.6% in each of the next five years. The required ROE is 8.7%. Current book value is $12.40 per share and the firm pays no dividends. Krieger previously assumed residual income falls to zero immediately after five years, but has now decided to recalculate its estimated value using a persistence factor of 35%. The difference between the new valuation and the old one is closest to:
To answer this question, we need to establish the residual values using the following equations:
Earnings = prior year book value × ROE Equity charge = prior year book value × required ROE Residual income = earnings ? equity charge
Here is a table containing the relevant values.

Company value = $12.40 + the sum of the residual incomes
Assuming residual value drops to zero after year five, the company is valued at $15.46 per share.
Now, we modify the model to reflect the persistence factor of 35%. The only value that persistence factor effects is the terminal value. Instead of discounting the Year 5 residual income by 1 + required ROE, we discount it by 1 + required ROE ? persistence factor. The new values are as follows:
|
Book Value |

Year 3 |

Value |
$12.40 |

For a total value of $15.78 per share, or $0.32 higher than the original value.
