Bu çalışmanın amacı, bazı finansal ve finansal olmayan parametreler yardımıyla finansal tablolardaki potansiyel hile riskini araştırmaktır. Hile riskinin tespiti için BIST şirketleri içerisinden Benford yasasına uyum kriterine göre kontrol ve risk grupları belirlenmiştir. Hile riskinde etkili olabilecek faktörler olarak; sektör, BIST risk grupları, bağımsız denetim firmalarının büyüklüğü, bağımsız denetim yükümlülüğü ve bağımsız yönetim kurulu üye sayısı olmak üzere beş değişken seçilmiştir.
Bu amaçla BIST reel sektörde işlem gören şirketlerin 2008-2017 yılları için bilanço ve gelir tabloları veri seti olarak alınmıştır. Finansal tabloların Benford yasasına uygunluğunu ölçmek için veri setine Benford analizi uygulanmıştır. T-Testi, ANOVA ve TUKEY testleri gruplar arasındaki farklılıkarın analiz edilmesinde kullanılmıştır. Sonuç olarak, şirket grupları arasında hile riski açısından anlamlı farklar belirlenmiş dolayısıyla söz konusu değişkenlerin finansal tablolarda hile riskini etkilediği tespit edilmiştir. Şirket sahipleri, muhasebe meslek mensupları, denetçiler ve vergi otoritesi gibi çevrelerin bu yöntemi kırmızı bayrakları tespit etmek ve denetim hedeflerini seçmek için kullanabileceği değerlendirilmektedir.
