This question tests AU-C Section 210 on terms of engagement and independence under AICPA standards. The key facts are lack of independence due to prohibited services throughout the engagement. Issuing a disclaimer and stating non-independence is appropriate because AU-C 210 prohibits any opinion when independence is impaired, requiring a disclaimer. Choice A is incorrect because unmodified opinions require independence per AU-C 200. Choices C and D are incorrect because qualified or adverse opinions imply some audit work under independence, which is invalid per AU-C 210. Auditors must assess independence before accepting engagements. Professional judgment involves recognizing that independence impairments preclude opinion issuance.

This question tests AU-C Section 570 on going concern under AICPA standards. The key facts are substantial doubt about going concern with adequate disclosures, and an otherwise unmodified opinion. Adding an emphasis-of-matter paragraph with a going concern heading and issuing an unmodified opinion is required because AU-C 570 mandates such paragraphs when substantial doubt exists with adequate disclosure. Choice A is incorrect because qualified opinions are not used for going concern uncertainties per AU-C 570. Choices C and D are incorrect because other-matter paragraphs are not specified for going concern under AU-C 570, and disclaimers are inappropriate unless disclosures are inadequate. Auditors must assess management's plans and disclosures to determine report modifications. Professional judgment involves evaluating the reasonableness of disclosures without qualifying the opinion for uncertainties.

This question tests AU-C Section 706 on emphasis-of-matter paragraphs in the auditor's report under AICPA standards. The key facts are a reasonably possible unfavorable litigation outcome with adequate disclosure, fundamental to users' understanding but not affecting the opinion. Adding an emphasis-of-matter paragraph and issuing an unmodified opinion aligns with AU-C 706, which requires such paragraphs for matters fundamental to users' understanding. Choice A is incorrect because qualified opinions are for misstatements or scope limitations per AU-C 705, not uncertainties. Choices C and D are incorrect because other-matter paragraphs are for additional information not fundamental per AU-C 706, and disclaimers are for scope limitations under AU-C 705. Auditors must evaluate if uncertainties are adequately disclosed and fundamental to decide on emphasis paragraphs. Professional judgment involves assessing the potential impact on users without modifying the opinion unless disclosure is inadequate.

This question tests AS 3101 on modifications for scope limitations under PCAOB standards. The key facts are inability to obtain evidence on significant revenue due to incomplete records, with material and pervasive effects. A disclaimer of opinion is appropriate because AS 3101 requires disclaimers when scope limitations are pervasive and prevent opinion formation. Choice A is incorrect because qualified opinions apply to non-pervasive limitations per AS 3101. Choices B and D are incorrect because adverse opinions are for misstatements under AS 3101, and unqualified with emphasis does not address evidence failures. Auditors should evaluate alternative evidence sources before disclaiming. Professional judgment requires assessing pervasiveness to decide between qualification and disclaimer.

The correct answer is B. An adverse opinion is issued when the financial statements are materially and pervasively misstated due to a departure from GAAP. Since the effects of failing to capitalize leases are pervasive, an adverse opinion is required. A qualified opinion (A) is appropriate for a material but not pervasive misstatement. A disclaimer of opinion (C) is issued for a pervasive scope limitation or a lack of independence. An explanatory paragraph (D) is used for other matters, such as a going concern issue, not for a known GAAP departure.

The correct answer is B. When an auditor concludes that substantial doubt about an entity's ability to continue as a going concern exists, but the disclosures in the financial statements are adequate, the auditor should issue an unmodified opinion. However, the report must be modified to include an emphasis-of-matter paragraph (for a nonissuer) or an explanatory paragraph (for an issuer) to draw users' attention to the matter. A qualified, adverse, or disclaimer of opinion (A, C, D) would be inappropriate as long as the disclosure is adequate and sufficient evidence was obtained.

The correct answer is C. This scenario describes a circumstance-imposed scope limitation. Because the auditor could not obtain sufficient appropriate evidence about a highly material and pervasive account (inventory), the auditor is unable to form an opinion on the financial statements as a whole. Therefore, a disclaimer of opinion is appropriate. A qualified opinion (A) would be used if the effect was material but not pervasive. An adverse opinion (B) is for GAAP departures, not scope limitations. An emphasis-of-matter paragraph (D) is not used for scope limitations.

The correct answer is D. This situation represents a departure from GAAP that is material but not pervasive. Since the effects are confined to specific accounts and do not fundamentally misrepresent the financial statements as a whole, a qualified opinion is appropriate. An adverse opinion (A) would be issued if the misstatement were both material and pervasive. A disclaimer of opinion (B) is for scope limitations. An other-matter paragraph (C) is not used to report a known material misstatement.

The correct answer is B. The failure to include required disclosures, such as management's plans regarding a going concern issue, is a departure from GAAP. If this departure is material, the auditor should issue either a qualified opinion (if not pervasive) or an adverse opinion (if pervasive). An unmodified opinion with an emphasis-of-matter paragraph (A) is only appropriate when disclosures are adequate. A disclaimer of opinion (C) is for a scope limitation. An other-matter paragraph (D) is not used for a GAAP departure.

The correct answer is B. When auditing financial statements prepared under a special purpose framework (like a regulatory basis), the auditor's report must include an emphasis-of-matter paragraph to highlight the basis of accounting and refer to the note describing it. Additionally, if the framework is not designed for general use (such as regulatory or contractual bases), an other-matter paragraph must be included to restrict the use of the report to specified parties. A qualified or adverse opinion (A, D) is not appropriate if the statements conform to the special purpose framework.
