Cost of acquisition rules clarified: FMV option and acquisition cost deemed nil when indeterminable, affecting capital gains computation.
Clause 90 defines cost of improvement as nil for intangible assets and permits post reference date expenditure for other assets; sets cost of acquisition as purchase price or previous owner's purchase price and deems cost nil where indeterminable; provides tailored rules for financial assets to avoid taxing non economic gains; and allows a fair market value option as cost of acquisition for earlier acquisitions to reflect market and inflationary changes.
