On 30 November 2017, the OECD announced an update to its guidance on the implementation of Country-by-Country (CbC) reporting. The update includes additional guidance on how to report amounts taken from financial statements prepared using fair value accounting; how to treat a negative figure for accumulated earnings in Table 1; how to treat mergers/acquisitions/de-mergers; how to treat short accounting periods; and the definition of total consolidated group revenue.
