a) Corrected COGS = $1,330,000 Corrected COGS = Reported COGS + Understatement of Ending Inventory for 2019 - Understatement of Ending Inventory for 2018
Given information:
Reported COGS = $1,300,000
Understatement of Ending Inventory for 2019 = $90,000
Understatement of Ending Inventory for 2018 = $60,000
Corrected COGS = $1,300,000 + $90,000 - $60,000
Corrected COGS = $1,330,000
b) To calculate the corrected Retained Earnings for the year ended May 31, 2019, we need to adjust the reported Retained Earnings by considering the change in COGS.
Change in Retained Earnings = Corrected COGS - Reported COGS
Change in Retained Earnings = $1,330,000 - $1,300,000
Change in Retained Earnings = $30,000
Corrected Retained Earnings = Reported Retained Earnings + Change in Retained Earnings
Given information:
Reported Retained Earnings = $4,000,000
Corrected Retained Earnings = $4,000,000 + $30,000
Corrected Retained Earnings = $4,030,000
Therefore, the corrected Cost of Goods Sold for the year ended May 31, 2019, is $1,330,000, and the corrected Retained Earnings for the year ended May 31, 2019, is $4,030,000.
