Answer:
initial investment in Ace Corporation = $1,065,000
Explanation:
initial investment in Ace Corporation = December 31st balance - (25% x net income reported) + (25% x distributed dividends)
initial investment in Ace Corporation = $1,170,000 - (25% x $700,000) + (25% x $280,000) = $1,170,000 - $175,000 + $70,000 = $1,065,000
When using the equity, reported net income increases the investment account while dividends decrease it.
