Formula sheets, the key method steps for every topic and 4 practice problems, with full solutions at the back.
An asset costs €50,000, has a residual value of €5,000 and a useful life of 5 years. What is the annual straight-line depreciation?
Company P buys 70% of the voting shares of S and gains control. How does P report S in its group accounts?
A computer system costs €12 000, has a useful life of 5 years and a salvage value of €2 000. Using the double-declining-balance method (without switching to straight-line), find the depreciation charge D in year 3.
A machine costs €50 000, has a useful life of 8 years and a salvage value of €5 000. Using the sum-of-the-years’-digits method, find the depreciation charge D in year 5.
Answer: B · €9,000
(Cost − residual value) ÷ useful life = (€50,000 − €5,000) ÷ 5 = €9,000 per year.
Answer: C · Consolidate 100% of S line by line and show a non-controlling interest
A subsidiary is consolidated line by line at 100%. The 30% owned by others is shown as a non-controlling interest within equity.
Answer: D = 1728 €
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).
