The share buyback for each company is $10 million / $50 per share = 200,000 shares.
Remaining shares for each company = 50 million ? 200,000 = 49.8 million shares.
For Solar Automotive Industries:
Solar Automotive Industries’ current BVPS = $500 million / 50 million = $10.
The market price per share of $50 is greater than the BVPS of $10.
Book value after repurchase = $500 million – $10 million = $490 million
BVPS = $490 million / 49.8 million = $9.84
BVPS decreased by $0.16
For Winnipeg Auto Unlimited:
Winnipeg Auto Unlimited’s current BVPS = $900 million / 50 million = $18.
The market price per share of $50 is greater than the BVPS of $18.
Book value after repurchase = $900 million – $10 million = $890 million
BVPS = $890 million / 49.8 million = $17.87
BVPS decreased by $0.13.
In the case of both Solar Automotive Industries and Winnipeg Auto Unlimited, book value per share (BVPS) decreased because the share price is greater than the original BVPS. If the share prices were less than the original BVPS, then the BVPS after the repurchase for each firm would have increased.
