Answer:
Additional paid-in capital is $4,074,000.
Step-by-step explanation:
In 2020, Sheffield issued $102 per share and there were 97,000 shares of convertible preferred stock.
Preferred stock = 97,000 shares × $102 = $9,894,000
Also we were told that one preferred stock can be converted to 3 common stock i.e. 3 × Preferred stock = Common stock
Therefore, Common stock = [(97000 shares × 3 shares) × $20] = $5,820,000
Additional paid-in capital = $9,894,000 - $5,820,000 = $4,074,000.
