International Accounting Standards (IAS) were issued by the IASC from 1973 to 2000. The IASB replaced the IASC in 2001. Since then, the IASB has amended some IAS, has proposed to amend other IAS, has proposed to replace some IAS with new International Financial Reporting Standards (IFRS), and has proposed certain new IFRS on topics for which there was no previous IAS. Through committees, both the IASC and the IASB also issue Interpretations of Standards. Financial statements may not be described as complying with International Accounting Standards unless they comply with all of the requirements of each applicable Standard and each applicable Interpretation.
