Qualified opinion，有保留的意见书，指审计师对财务报表提出的附有保留意见的一种审计意见书。保留意见的形式包括对财务报表中一个或多个特定项目的异议、拒绝发表意见或表示反对意见等。在作出保留意见时，审计师可说明其理由。如果没有说明保留意见的理由，简式审计报告中对意见的表述可以用“限于……”或“除了……”开头。（元照英美法词典）

投资百科中对其的释义如下，供参考：

A qualified opinion is a statement issued in an auditor's report that accompanies a company's audited financial statements. It is an auditor's opinion that suggests the financial information provided by a company was limited in scope or there was a material issue with regard to the application of generally accepted accounting principles (GAAP)—but one that is not pervasive.

除了保留意见之外，审计报告中常见的还有其他三种审计意见：

Unqualified opinion无保留的意见书。对财务报表提出的一种审计意见书。在该意见书中，一个合格的公共会计师确认所有财务报表系公正地作出，且与上一年度财务报表的会计方法相一致。在作出意见书的过程中，公共会计师的行为需符合公认的会计准则。

Adverse opinion否定意见。When issuing an adverse opinion, the auditor concludes that the financial statements do not present the entity's financial position, results of operations, and cash flows in conformity with GAAP. This type of opinion is only issued when the financial statements contain very material departures from GAAP. 在发表反对意见时, 审计师的结论是, 财务报表没有按照公认会计原则列报该实体的财务状况、业务结果和现金流量。只有在财务报表中存在与公认会计原则的重大背离的情况下, 才会发表这类意见。‎

Disclaimer of opinion无法表示意见。A disclaimer of opinion is issued when the auditor is unable to form an opinion on an entity's financial statements. A disclaimer may be issued in cases when: (1) the auditor is not independent with respect to the entity under audit, (2) a material scope limitation exists, or (3) a significant uncertainty exists.当审计师无法对一个实体的财务报表形成意见时, 就会发表免责声明。在以下情况下, 可以发出免责声明: (1) 审计师对被审计的实体不独立, (2) 存在重大范围限制, 或 (3) 存在重大不确定性。

以下为相关双语示例：

The scope limitation on the audit of the financial statements for the year ended 31 December 2007 together with the qualified opinion of the auditors are set out in the “Independent Auditor’s Report” on page 27. 

审核截至二零零七年十二月三十一日止年度财务报表之范围限制，连同核数师之保留意见载于第2 7页之「独立核数师报告书」。
