Difficulty: HardSettlement Dates, Trade Confirmations, and Corporate Actions

An investor purchases 400 shares of XYZ Corporation common stock at $55.00 per share in a cash account. Subsequently, the corporation executes a 5-for-4 stock split, and later in the same year pays a 10% stock dividend. Assuming no other transactions or cash liquidations occur, what is the investor's adjusted cost basis per share (in USD) after both corporate actions are completed?

Answer: 40 USD

Answer

The investor's adjusted cost basis per share is $40.00.
The total cost basis of the holding remains unchanged at 22,000(22,000 ( 400 \text{ shares} \times \55.0055.00). The 5-for-4 split increases the share count from 400 to 500 shares (400×1.25400 \times 1.25). The subsequent 10% stock dividend adds another 10% to the 500-share position, yielding 550 total shares (500×1.10500 \times 1.10). Dividing the unchanged 22,000totalcostbasisby550sharesproducesanadjustedcostbasisof22,000 total cost basis by 550 shares produces an adjusted cost basis of 40.00 per share.

Step-by-Step Solution

1
Calculate the total initial cost basis of the stock position.
Total cost basis is 400 shares×$55.00=$22,000400 \text{ shares} \times \$55.00 = \$22,000.
Stock splits and stock dividends alter the number of outstanding shares and per-share price, but do not change the total economic cost basis of the position.
2
Adjust the share quantity for the 5-for-4 forward stock split.
Share count becomes 400×(54)=500400 \times \left(\frac{5}{4}\right) = 500 shares.
A 5-for-4 split increases share count by a factor of 1.25 (or 125%).
3
Adjust the share quantity for the subsequent 10% stock dividend.
Final share count becomes 500×(1+0.10)=550500 \times (1 + 0.10) = 550 shares.
The 10% stock dividend applies to the current post-split balance of 500 shares.
4
Compute the updated per-share cost basis.
\frac{\$22,000}{550 \text{ shares}} = \$40.00 \text{ per share}.
Dividing the total position cost by the updated final share count gives the new cost basis per share.
