Assume you are the partner in charge of the 2016 audit of Steeler Corporation, a private company. The audit report has not yet been prepared. In each independent situation following, indicate the appropriate action to be taken. The possible actions are as follows: 1. Issue an unmodified opinion audit report. 2. Qualify the opinion paragraph. 3. Issue an unmodified opinion with an explanatory paragraph. 4. Issue an unmodified opinion based in part on the report of another auditor. 5. Issue an adverse opinion. 6. Disclaim an opinion. The situations are as follows: Steeler Corporation carries its property, plant, and equipment accounts at current market values. Current market values exceed historical cost by a highly material amount, and the effects are pervasive throughout the financial statements. Management of Steeler Corporation refuses to allow you to observe, or make, any counts of inventory. The recorded book value of inventory is highly material, making up most of the Steelers current assets. You were unable to confirm accounts receivable with Steeler's customers. However, because of detailed sales and cash receipts records, you were able to perform reliable alternative audit procedures. One week before the end of fieldwork, you discover that the audit manager on the Steeler engagement owns a material amount of Steeler's common stock. You relied upon another CPA firm to perform part of the audit. Although you were the principal auditor, the other firm audited a material portion of the financial statements. You wish to refer to the other firm in your report. You have substantial doubt about Steeler's ability to continue as a going concern but Steeler has adequately disclosed this in the Financial statements. Steeler Corporation changed its method of computing depreciation in 2016. You concur with the change and the change is properly disclosed in the financial statement footnotes. Ten days after the balance sheet date, one of Steeler's buildings was destroyed by a fire. Steeler refuses to disclose this information in a footnote to the financial statements, but you believe disclosure is required to conform with GAAP. The amount of the uninsured loss was material, but not highly material
