VakıfBank Annual Report 2018 121 Key Audit Matters How Our Audit Addressed the Key Audit Matter Expected Credit Loss in Accordance With TFRS 9 “Financial Instruments Standard” (“TFRS 9”) The Bank has total expected credit losses of TL 10,860,390 thousands in respect to loans of TL 232,406,907 thousands which represent a significant portion of the Bank’s total assets in its unconsolidated financial statements as at 31 December 2018. Explanations and notes related to provision for impairment of loans are presented Section III Part VII, Section III Part VIII, Section V Part I-5 and Section V Part II-7 in the accompanying unconsolidated financial statements as at 31 December 2018. As of 1 January 2018, the Bank started to recognize provision for impairment of loans in accordance with “TFRS 9 Financial Instruments” requirements in line with the “Regulation on the Procedures and Principles for Classification of Loans and Provisions to be Provided” as published in the Official Gazette dated 22 June 2016 numbered 29750. Accordingly, provisioning rules applicable as at 31 December 2017 under the previous BRSA regulation have changed with the application of expected credit loss model under TFRS 9 together with the rules on classification of loans as per their credit risk (staging). The Bank exercises significant decisions using subjective judgement, interpretation and assumptions over when and how much to record as loan impairment. The Bank determines staging of credit identifying significant increase in credit risk with assess8ments and default events presented Section Three Part VII in the accompanying unconsolidated financial statements. Information used in the expected credit loss assessment such as historical loss experiences, current conditions and macroeconomic expectations should be supportable and appropriate. With respect to stage classification of loans and calculation of expected credit losses in accordance with TFRS 9, we have assessed policy, procedure and management principles of the Bank within the scope of our audit. We assessed the design and the operating effectiveness of relevant controls implemented in accordance with these principles. Within the framework of the policies and procedures applied by the Bank, together with our financial risk experts, we have checked and assessed the appropriateness of the methods used in the model developed for staging of loans and calculation of expected credit losses in accordance with TFRS 9. For forward looking assumptions (including macro-economic factors) made by the Bank’s management in its expected credit loss calculation, we held discussions with management and evaluated the assumptions using publicly available information. We have tested model calculations through re-performance together with our modelling specialists on a sample selection basis. Our audit processes also include the following procedures: • The basic and important estimates and the assumptions related to macroeconomic variables, significant increase in credit risk in the calculation of expected credit losses, default definition, probability of default and loss given default were assessed and tested with the help of our financial risk experts. • We have checked expected credit losses determined based on individual assessment per Bank’s policy by means of supporting data, and evaluated appropriateness via communications with management. • We checked sources for data used in expected credit losses calculations. We assessed reliability and completeness of the data used in expected credit losses calculations with our information systems specialists. We checked the accuracy of resultant expected credit loss calculations on a sample basis.
