Retained earnings represent:
A company "sells" inventory to a bank and must buy it back later at a higher price, keeping the risks and rewards. How should it be accounted for?
A machine costs €80 000, has a useful life of 6 years and a salvage value of €16 000. Using the double-declining-balance method (without switching to straight-line), find the depreciation charge D in year 2.
A computer system costs €45 000, has a useful life of 8 years and a salvage value of €4 500. Using the sum-of-the-years’-digits method, find the depreciation charge D in year 6.
Answer: D · Accumulated profits that have not been paid out as dividends
Retained earnings are cumulative net profits minus dividends; they are part of equity, not a pile of cash.
Answer: C · As a secured loan, not a sale
Control and risks stay with the company, so the transaction is in substance borrowing secured on inventory. The price difference is an interest cost.
Answer: D = 17778 €
Depreciation spreads the cost of an asset over its useful life. Straight-line: (cost − salvage value)/life every year. Double-declining balance: 2/life times the book value at the start of each year, so the charge falls each year (salvage is not subtracted, but the book value never goes below it). Sum-of-the-years’-digits: (cost − salvage) × remaining life/(1 + 2 + … + n).
