Therefore, all premiums obtained from aforementioned treaties are accounted on the fire branch. According to the letter dated August 2, 2011 and numbered B.02.1.HZN.0.10.03.01/38732 sent by the Republic of Turkey Ministry of Treasury and Finance to the Company, it is allowed to use average rate calculated over separately reported fire and earthquake premiums for unclassified premiums of proportioned treaties. Furthermore, according to the letter dated August 12, 2011 sent by the Republic of Turkey Ministry of Treasury and Finance to the Company, prospective application as at June 30, 2011 effective from January 1, 2011 is allowed since retrospective application is impossible. Accordingly, financial statements prepared As of December 31, 2022, premiums obtained from foreign proportioned treaties are accounted on the basis of average earthquake premium ratio calculated from foreign proportioned treaties over the period of January 1, 2022 – December 31, 2022. The same ratio is used for unproportioned reinsurance treaties in accordance with the Communiqué released on July 28, 2010 and numbered 27655 “Communiqué on Amendments to Communiqué on Technical Reserves for Insurance, Reinsurance and Pension Companies and the Related Assets That Should Be Invested Against Those Technical Reserves”. Distribution of commissions and claims between the fire and earthquake branches is parallel with the aforementioned method. According to 16 th article of “Circular on Actuarial Chain Ladder Method (2010/12)” dated September 20, 2010 and announced by Republic of Turkey Ministry of Treasury and Finance, ACLM calculation should be made through main branches. However, as of December 31, 2012, the Company has calculated ACLM reserve for General Damages main branch as two separate subbranches namely agriculture and non-agriculture branches. Because, Agriculture and Engineering subbranches under General Damages main branch have different characteristics in conversion process of outstanding losses to paid losses, IBNR calculation of General Damages branch produces unreliable and improper results. The Company applied to Republic of Turkey Ministry of Treasury and Finance on January 17, 2013 with letter numbered 300, so as to receive permission to calculate IBNR reserve for General Damages branch as agriculture and non-agriculture subbranches separately. Republic of Turkey Ministry of Treasury and Finance has given permission the Company in order to calculate IBNR reserve for General Damages within two subbranches with the letter dated January 28, 2013 and numbered 24179134. As at December 31, 2022, the Company recognised the amount that arose due to change in calculation method for IBNR on General Damages branch. Significant changes in accounting policies and significant accounting misstatements are applied retrospectively and prior period financial statements are restated. If the changes in accounting estimates are for only one period, they are applied prospectively both in the current period when the change is made and in the future period if the change is made. Critical accounting judgements used in applying the Company’s accounting policies are explained in 3 – Significant accounting estimates and requirements . 196 MİLLİ RE 2022 ANNUAL REPORT Notes to the Consolidated Financial Statements As of December 31, 2022 Millî Reasürans Türk Anonim Şirketi (Currency: Turkish Lira (TL)) Convenience Translation of Financial Statements and Related Disclosures and Footnotes Originally Issued in Turkish, See Note 2.1.1 GENERAL INFORMATION FINANCIAL RIGHTS PROVIDED TO THE MEMBERS OF THE GOVERNING BODY AND SENIOR EXECUTIVES RESEARCH & DEVELOPMENT ACTIVITIES ACTIVITIES AND MAJOR DEVELOPMENTS RELATED TO ACTIVITIES
