ATD Level III: Advanced Accounting, Costing, Auditing and Taxation
What the level tests
Level III tests synthesis. You must prepare and interpret advanced financial statements, apply cost accounting methods, understand audit evidence and risk, and compute tax liabilities.
Concepts to master
Advanced financial accounting: consolidation basics (parent and subsidiary, goodwill, non-controlling interest), branch and departmental accounts, incomplete records, and interpretation of financial statements. Cost accounting: material, labour and overhead costing; job, batch and process costing; marginal versus absorption costing; break-even analysis. Auditing: objectives of an audit, audit risk, materiality, evidence, internal controls and the auditor's report. Taxation: chargeable income, allowable deductions, capital allowances and the difference between tax avoidance and evasion.
Traps
In consolidation, do not add the subsidiary's entire share capital and reserves to the group; eliminate the investment and recognise only the group's share. In process costing, normal loss is often valued at scrap value, not full cost. In auditing, 'reasonable assurance' is not a guarantee. In tax, private expenses are not allowable, and a question asking for tax payable is not asking for accounting profit.
Worked rule
For a simple consolidation: combine assets and liabilities line by line, eliminate investment against the subsidiary's equity, then recognise goodwill and non-controlling interest. Check: group retained earnings = parent's retained earnings plus parent's share of subsidiary's post-acquisition retained earnings less unrealised profit. Always state the basis before calculating.
