The total non-controlling interest in the consolidated balance sheet is calculated as follows:
Total assets of Southdale Company = common stock + other contributed capital + retained earnings
= $800,000 + $400,000 + $330,000
= $1,530,000
Park Company's 80% interest in Southdale Company's stock = 80% x $1,540,000 = $1,232,000
Non-controlling interest = Total assets - Park Company's interest
= $1,530,000 - $1,232,000
= $298,000
Therefore, the total non-controlling interest to be reported in the consolidated balance sheet is $298,000.
