The documentation and reasoning behind this choice of accounting method is most likely to be found O in the current year's audit file, and typically located in the risk assessment section under substantive tests of details. O in the minutes of the board of directors meeting, as this choice of depreciation method has to be voted on by senior management at least once a year. O in the internal audit function, as this function, per generally accepted auditing standards, maintains responsibility for selection of appropriate accounting methods. O in the permanent audit file, which typically contains details of significant accounting methods used by the client.
