Aurora Medical Systems repurchased and cancelled 2,000 of its own common shares at a price of $28 per share as part of a broader capital restructuring initiative. The shares had originally been issued at an average carrying amount of $24 per share. The company also has a $5,000 balance in contributed surplus arising from prior share repurchase transactions.

Canyon Fibre Corp. has a capital structure consisting of preferred shares with a carrying value of $300,000 that carry an 8 percent cumulative dividend, and common shares with a carrying value of $900,000. The preferred shares are entitled to receive their stated dividend each year and, after all cumulative dividends have been satisfied, they participate with common shareholders on a pro rata basis in any remaining dividends. Due to financial difficulties, the company did not declare dividends in the previous two years. In the current year, the company returns to profitability but declares total dividends of only $120,000, citing liquidity constraints. Management indicates that it would like to treat shareholders fairly, but acknowledges that contractual rights must be respected. The CFO is preparing the dividend allocation and must determine how the declared amount is distributed between preferred and common shareholders. What amount will be allocated to common shareholders?

Northern Crest Ltd. is preparing its year-end statement of changes in equity. The assistant controller calculated ending retained earnings by starting with the opening balance of $1,200,000 and adding net income of $500,000. During the year, the company declared $200,000 in cash dividends and issued a 10 percent stock dividend recorded at a fair value of $150,000. The assistant controller also included the proceeds from a $600,000 share issuance and an unrealized gain of $80,000 recorded in other comprehensive income in the retained earnings calculation, arguing that both increased total equity. In addition, a prior period error adjustment of $50,000 (net of tax) related to understated expenses from the previous year was recorded directly in retained earnings. The CFO is reviewing the calculation and removing inappropriate inclusions while ensuring all required adjustments are reflected. What is the correct ending retained earnings balance?
