The closing balances can be computed as beginning balances + changes in the year = closing balances:
Common stock = 10,000 + 200,000 = $210,000
Preferred stock =  5,000 + 10,000 =    $15,000
Additional paid in capital = 2,800,000 + 1,000 = $2,801,000
Treasury stock  = 180,000 - 60,000 = $120,000
Retained earnings 9,600 + 25,000 - 3,000 = $31,600
