13 Selected financial data The financial results in this Annual Report are based on Aegon’s consolidated  financial statements, which have been prepared in accordance with International  Financial Reporting Standards (IFRS) as adopted by the European Union. Application of the accounting policies in the preparation  of the financial statements requires management to apply  judgment involving assumptions and estimates concerning  future results or other developments, including the likelihood,  timing or amount of future transactions or events. There can  be no assurance that actual results will not differ materially  from those estimates. Accounting policies that are critical to  the presentation of the financial statements and that require  complex estimates or significant judgment are described in the  notes to the financial statements. A summary of historical financial data is provided in the table  below.
