會計師審計品質與財物報表重編之關聯性

Audit Quality and Restated Financial Statements

近幾年來，層出不窮的會計舞弊事件嚴重打擊資大眾對會計師之信心，據統計顯示，也愈來愈多㈶務報表因不符合一般公認會計原則被要求重編，投資大眾在市場上的損失也有趨高的比例與財務報表重編有關。本文主要探討會計師審計品質與財務報表重編發生之關係，並以民國91年至95年發生財務報表重編的台灣上市上櫃公司為研究對象，探討會計師審計品質財務報表重編之關聯性。本研究以非審計公費重大性、事務所規模、產業專精與查核年資為會計師審計品質代理變數。研究結果發現，非審計公費若不具重大性、會計師事務所為產業專精者或查核年資越長，將可減少財務報表重編發生之可能性；事務所規模則受限於我國審計市場特性，無法在實證上獲得完全支持。實證結果也顯示，針對向下調整淨利之重編，僅產業專精與查核年資可降低重編發生可能性。此外，在查核過程與核閱過程下，會計師審計品質對財務報表重編有不同之影響效果。

In recent years, due to the increase in the number and size of financial restatements, government regulators have expressed great concern over restatements to correct non-GAAP financial statements. The restatements induce that investors lose confidence in the accountants because the misreports cause countless losses of investors. This study examines restatements in the period 2002-2006, together with matched control group of firms of similar time, industry, and firm size. We use a logit model to test whether the likelihood of a restatement is related to the audit quality (using nonaudit fee, auditor size, auditor industry specialization, and auditor tenure as proxies). We find that nonaudit fee exhibits a significant positively association with the occurrence of restatement. We also find auditor industry specialization and auditor tenure have a significant negatively association with the occurrence of restatement. We cannot fully document a significant negatively association between auditor size and restatement. Besides, we investigate restatements which decreasing previous income, and find that only auditor industry specialization and auditor tenure have a significant negatively association with restatement. We also consider a sample of financial statements audited and financial statements reviewed. Our results indicate that audit quality have different influence on financial statements audited or those reviewed.
