The purpose of this study is to investigate whether there is a difference between the indicators of working capital management of companies listed in Borsa Istanbul (BIST) in the period of 2000-2017 according to the financial statements prepared before and after International Financial Reporting Standards (IFRS). In this context, two different comparisons were made by using Wilcoxon Signed Rank test. First, it was made the comparison of five years period (2000-2004) before and five years period (2007-2011) after the adoption of international standards. On the other hand, it was compared with the five years period (2007-2011) before and five years period (2013-2017) after Turkish Commercial Law regulation in 2012. At the end of the study, it was determined according to both comparisons that although there is a significant difference between working capital management determinants in terms of Accounts Payable Period, there are no significant difference in terms of other variables (Accounts Receivable Period, Inventory Holding Period, Cash Conversion Period, Working Capital Level, and Return on Working Capital)
