 In their 2013 proposal for accounting for financial instruments, the Financial Accounting Standards Board also proposed a similar use of business model for classifying financial instruments.The concept of business model has also been introduced into the accounting of deferred taxes under International Financial Reporting Standards with 2010 amendments to IAS 12 addressing deferred taxes related to investment property.Both IASB and FASB have proposed using the concept of business model in the context of reporting a lessor's lease income and lease expense within their joint project on accounting for leases.
