Answer:
Pam and Jon's dividend income = $80,000 each
[ ($100000 Accumulated E&P + $60000 current E&P ) / 2] = $80,000
Statement of distribution for shareholders for tax purpose
Pam Jon
Total distribution $100,000 $100,000
Less: Dividend income $80,000 $80,000
$20,000 $20,000
Less: Stock basis $11,000 $26,000
Capital gain $9,000 $0
Therefore, Pam has a taxable gain of $9000 which reduces the stock basis to $0, whereas Jon has not any taxable gain but the stock basis has reduced to $6000 [$26000 - $20000]
