Dear Nehal,
Every compnay has to follow depreciation rates and method as prescribed in the Companies Act,1956. These rate are the minimum rates given under the statute.
Moreover, every compny at the time of purchase of any fixed asset has to make estimate of the useful life of the asset being used and decide the method of depreciating the same keeping in mind the requirement of the statute.
However, if compnay wants to depreciate its assets at higher rates than givan in cos. Act or at full value in the first year itself then it must provide justification for providing the same. If an auditor is satisfied with the justification given by the company and method of depre. employed he will not qualify his report u/s227(3).
METHOD OF DEPRECIATION ADOPTED BY THE COMPNY IS THE POLICY OF THE CO. WHERE RATE OF DEPN. IS THE ESTIMATE MADE BY THE COMPANY AT THE BALANCE SHEET DATE SINCE IT IS THE ULTIMATE AUTHORITY AND RESPONSIBILITY OF THE COMPANY FOR PREPARATION AND PRESENTATION OF THE FINANCIAL STATEMENTS FOR WHICH BOD TAKE RESPONSIBILITY THROUGH DIRECTORS RESPONSIBILITY STATEMENT. WE ARE ONLY WATCHDOGS.
As per the requirement of the relevent AS, Accounting policy can be changed only in the following cases:
1. It is requirement of statute
2. It is required for better presentation of financial statements
3. It is the requirement of AS by ICAI
with the proper justification to the notes to accounts. AS 1 requires to disclose details regarding depreciation on FA otherwise Co. Statutory auditor has a right to qualify his audit report.
In case of accounting estimates (Rate of Dep,.), if co. justifies the same it can change the same with due explanation in the notes to accounts. So Depn can be reversed.
E.g, the same is the case with BDR (Bad Debt Reserve)
Thus, 30% Depn can be reversed keeping in mind the above discussion.
