Valuation rule definitions clarify accountant qualifications, balance-sheet treatment, observable price, and control for related tax provisions. Definitions are prescribed for the purposes of rules 11 and 12, including accountant, balance sheet, book value of liabilities, connected person, foreign company or entity, observable price, right of management or control, specified date, telegraphic transfer buying rate, merchant banker, and recognised stock exchange. The rule sets qualification thresholds for accountants and recognised foreign valuers, specifies how balance sheets are determined in different cases, and adopts linked meanings from other provisions for cross-referenced terms.
