The
debates on the effect of independent audit rotation on audit quality can be considered
as two sides of a coin. On the one side, the idea that auditor rotation would
increase audit quality as it would strengthen auditor independence; on the
other side, the idea that auditor rotation can lead to loss of client and
sectoral-specific knowledge and the quality of audit would decrease. In this
context, the aim of the study is to investigate whether rotation practice in
independent audit affects the audit quality. For this purpose, 1230 firm-year
data obtained from non-financial companies quoted at the Borsa Istanbul between
the years of 2010-2017 are tested with regression analysis. The amount of
abnormal working capital accruals are used as a proxy for audit quality. The
results of the study indicate that there is no statistically significant
association between audit rotation practice and independent audit quality. In
other words, the results of the research do not provide any evidence to support
the idea that the quality of audit may improve after audit firm rotation

BAĞIMSIZ DENETİMDE ROTASYON DENETİM KALİTESİNİ NASIL ETKİLER?

Öz

Bağımsız denetimde rotasyon uygulamasının denetim
kalitesine etkisi üzerine yürütülen tartışmalar bir metal paranın iki yüzüne
benzetilebilir. Bir tarafta, denetçi rotasyonunun denetçinin bağımsızlığını
güçlendireceği ve denetim kalitesinin artacağı düşüncesi; diğer tarafta ise,
denetçi rotasyonu neticesinde denetçinin işletmeye ve sektöre özgü birikmiş
denetim bilgisini kaybedeceği ve denetim kalitesinin düşeceği düşüncesi yer
almaktadır. Bu çerçevede çalışmanın amacı, bağımsız denetimde rotasyon
uygulamasının denetim kalitesini nasıl etkilediğinin araştırılmasıdır. Bu amaç
doğrultusunda, 2010-2017 yılları arasında Borsa İstanbul’da işlem gören
finansal olmayan kuruluşlardan elde edilen 1230 şirket-yıl verisi regresyon
modeli ile analiz edilmiştir. Bağımsız denetim kalitesinin ölçülmesinde anormal
işletme sermayesi tahakkuklarından yararlanılmıştır. Araştırma sonuçları,
denetimde rotasyon uygulaması ile bağımsız denetim kalitesi arasında
istatistiksel olarak anlamlı bir ilişki olmadığını göstermektedir. Denetim
rotasyonu ile ilgili olarak, farklı ülke uygulamalarının incelenmesinin
düzenleyici otoritelere yararlı bilgiler sağlayacağı düşünülmektedir.
