Answer: credit of $213876.80 to Paid-in Capital in Excess of Par.
Explanation:
First and foremost, we have to calculate the exercised ratio which will be:
= Converted value for bonds / Total value if convertible bonds
= $1250000 / $4050000
= 0.3086
The unamortized premium will then be calculated thus:
= $1250000 + ($288000 × 0.3086) - (1250 × $30 × 30)
= $1250000 + $88876.80 - $1125000
= $213876.80
Therefore, credit of $213876.80 to Paid-in Capital in Excess of Par.
