Constant purchasing power accounting
Constant purchasing power accounting (CPPA) is an accounting model approved by the International Accounting Standards Board (IASB) and the US Financial Accounting Standards Board (FASB) as an alternative to traditional historical cost accounting under hyper-inflationary environments and all other economic environments. Under this IFRS and US GAAP authorized system, financial capital maintenance is always measured in units of constant purchasing power (CPP) in terms of a Daily CPI (consumer price index) during low inflation, high inflation, hyperinflation and deflation; i.e., during all possible economic environments. During all economic environments it can also be measured in a monetized daily indexed unit of account (e.g. the Unidad de Fomento in Chile) or in terms of a daily relatively stable foreign currency parallel rate, particularly during hyperinflation when a government refuses to publish CPI data.
