Answer:
$257400
Step-by-step explanation:
Under Sec. 1366(a) and Sec. 1377(a), a pro rata share is the tax payers hare of loss determined on a per-day and then a per-share basis. Cobra shareholder includes his or her pro rata share of loss from the cobra.
The ordinary loss for the whole year was $474,500, Therefore the loss per day was $1300 per day ( $474,500 ÷ 365 days).
Since Mr. and Mrs. Wise owned 50% of the stock for the full year and the other 50% for 31 days, their share of loss = [ $474,500/2 + (31 days × $1300 × 50%)] = $237250 + $20150 = $257400
