BİST 30'daki Şirketlerin 2024 Yılı İçin Kilit Denetim Konularını ve Sektörel Analizleri: Uluslararası Dört Büyük Denetim Şirketinin Raporlarına Yönelik Bir İnceleme

Year 2025, Volume: 5 Issue: 2, 184 - 196, 01.08.2025

Abstract

2008–2009 küresel finansal krizi, bağımsız denetim uygulamalarının şeffaflığı ve etkinliği konusunda önemli yetersizlikleri ortaya koymuştur. Düzenleyici kurumlar tarafından getirilen temel reformlardan biri, ISA 701 kapsamında Önemli Denetim Konularının (KAM'ler) açıklanmasının zorunlu hale getirilmesidir. Bu çalışma, yalnızca 2024 yılında BIST 30 şirketlerini denetleyen dört büyükler denetim firmaları (PwC, EY, KPMG, Deloitte) üzerine odaklanmakta ve sektöre özgü faktörlerin KAM’lerin niteliği ve sıklığını nasıl şekillendirdiğini incelemektedir. Daha önce önerilen dört büyükler dışı firmalarla karşılaştırmaların aksine, bu çalışma açıkça böyle bir analizden kaçınmakta ve farklı denetim firması türleri arasında denetim kalitesini karşılaştırmayı amaçlamamaktadır. Araştırma kapsamında, nitel tematik analiz ile destekleyici frekans analizlerinin bir arada kullanıldığı betimsel içerik analizi yöntemi uygulanmıştır.. Temalar, eşli kodlama yöntemiyle çıkarılmakla birlikte, çalışma betimleyici nitelikte kalmakta ve nedensel ya da çıkarımsal istatistiksel testler yürüttüğünü iddia etmemektedir. Bulgular, dört büyükler tarafından uygulanan standartlaştırılmış denetim raporlamasının sektöre özgü riskleri nasıl yansıttığını anlamaya katkı sağlamaktadır.

Key Audit Matters and Sectoral Analyses of Companies in BIST 30 For 2024: A Review of Reports from Big Four International Audit Firms

Year 2025, Volume: 5 Issue: 2, 184 - 196, 01.08.2025

Abstract

The 2008–2009 global financial crisis revealed significant shortcomings in the transparency and effectiveness of external audit practices. A key reform introduced by regulatory bodies was the mandatory disclosure of Key Audit Matters (KAMs) under ISA 701. This study focuses exclusively on BIST 30 companies audited by Big Four audit firms (PwC, EY, KPMG, Deloitte) in 2024. It explores how sector-specific factors shape the nature and frequency of KAMs. Contrary to earlier suggestions of comparisons with non-Big Four firms, this study explicitly excludes such analysis and does not aim to contrast audit quality across different firm types. This study employs a hybrid content analysis, combining qualitative thematic coding with descriptive statistical summaries (frequencies and distributions). It does not incorporate inferential or causal statistical testing; thus, it should be classified as a qualitative-dominant design. While themes are extracted using peer-coded content analysis, the study remains descriptive in nature and does not claim to conduct causal or inferential statistical tests. Findings contribute to understanding how standardized audit reporting by the Big Four reflects sector-specific risks.
