Implied authorisation by the IASB to revoke the stable measuring unit assumption in low inflationary economies.

Paragraph 40 of IAS 29 can be taken as revoking the stable measuring unit assumption in low inflationary economies as the word inflation is used instead of hyperinflation.

"Par 40 The disclosures required by this Standard are needed to make clear the basis of dealing with the effects of inflation in the financial statements."
Authorisation to revoke the stable measuring unit assumption in low inflationary economies can also be taken to be implied from the IASB´s Framework for the Preparation and Presentation of Financial Statements, Concepts of Capital Maintenance and the Determination of Profit:

Par 104. The concepts of capital in paragraph 102 give rise to the following concepts of capital maintenance:

(a) Financial capital maintenance.

Under this concept a profit is earned only if the financial (or money) amount of the net assets at the end of the period exceeds the financial (or money) amount of net assets at the beginning of the period, after excluding any distributions to, and contributions from, owners during the period. Financial capital maintenance can be measured in either nominal monetary units or units of constant purchasing power.

Units of constant purchasing power is generally taken as updating constant real value non-monetary items in terms of the monthly change in the Consumer Price Index in low inflationary economies and daily at a daily index rate (see Unidade Real de Valor: "The exchange rate of URVs to cruzeiros reais was recalculated and published daily by the government.") or the parallel exchange rate (in the absence of a daily index rate) in hyperinflationary economies (See Hyperinflation).
