It is true that in CIS environment the trial balance always trial. However it can not be concluded that
the job of an auditor becomes simpler. There can still be some accounting errors like omission of certain entries, compensating errors, duplication of entries, errors of commission in the form of wrong account etc. The nature of transactions recorded in the books and appear in the trial balance should be focused.
The emergence of new forms of financial instruments like options and futures, derivatives, off balance sheet financing etc have given rise to further complexities in recording and disclosure of transactions.
In an audit, besides the tallying of a trial balance, there are also other issue like estimation of provision for depreciation, valuation of inventories, obtaining audit evidence, ensuring compliance procedure and carrying out substantive procedure, verification of assets & liabilities their valuation etc. which still requires judgement to be exercised by the auditor.
Responsibility of expressing an audit opinion and objectives of an audit are not changed in the audit in CIS environment. Therefore, it can be said that simply because of CIS environment and the trial balance has tallied it does not mean that the audit would become simpler.
