The following seven situations are related to possible audit reports and some of the paragraphs that are written in such reports. Unless otherwise stated, assume the amounts involved are substantial $($material$)$ and the clients are private corporations.

$1.$ The client deviated from $$GAAP$.$ Deviance is considered substantial $($material$)$ and all$-$encompassing $($pervasive$).$

$2.$ Customer inventory records are deficient, so the auditor has to reach conclusions about the reasonableness of the inventory figure in the financial statements by using alternative methods. Once the necessary tests have been done, the auditor is satisfied that he has sufficient evidence to support said amount.

$3.$ During the audit, the auditor obtains sufficient information that leads him to conclude that the continuity $($going concern$)$ of the company he is auditing is doubtful.

$4.$ The main audit firm $($group auditor$)$ decides not to assume responsibility for the audit work carried out by another firm $($component auditor$),$ which audited one of the subsidiaries owned by the parent company by $70\%($owned subsidiary$).$ The total assets and total income of the subsidiary represent $5\%$ and $8\%,$ respectively, of the total assets and debts of the parent company audited by the main firm. In turn, the other firm $($the secondary$)$ issued an unmodified opinion on the financial statements of the subsidiary.

$5.$ A company under audit changes from the FIFO inventory cost flow method to a different method that is not generally accepted $($non$-$GAAP$).$ Of course, the auditors do not agree with said change. The change severely affects all financial statements issued for that period.

$6.$ The client retained many of the accounting records during the audit process so that, by not making them available to the auditors, the auditors were unable to obtain sufficient and competent evidence to be able to reach conclusions about the reasonableness of the Equipment account, the which has a substantial balance.

$7.$ Client changed their estimate of doubtful accounts from $2\%$ to $3\%$ of credit sales for the year. The auditors believe that the change is reasonable.
