Answer and Explanation:
According to the scenario, computation of the given data are as follow:-
1) 15% Stock Dividend-
Retained Earnings = Increase Value of Retained Earnings - (Total Shares × 15% Stock Dividend × Increase Value of Per Share)
= $30,000,000 - (500,000 × 15% × $55)
= $30,000,000 - $4,125,000
= $25,875,000
2) 2-for-1 stock split-
Retained earnings = $30,000,000
The 2-for-1 stock split will not impact retained earnings.

c) Par value per share
Par value per share of stock dividend = $4
Par value per share of 2-for-1 stock split = $4 ÷ 2 = $2
According to the analysis, stock dividend will not make any impact.
