INDEPENDENT AUDITORS’ REPORT To The Members Of Oversea-Chinese Banking Corporation Limited Valuation of insurance contract liabilities (Refer to Notes 4, 22, 39 and 41 to the financial statements.) The key audit matter How the matter was addressed in our audit The Group’s insurance operations are entirely conducted through its subsidiary, Great Eastern Holdings Limited (GEH). We planned, scoped and issued group audit instructions to GEH’s auditors to obtain an independent auditors’ report of the significant component. The scope of reporting included valuation of liabilities of the insurance business. The Group’s insurance business comprises life and general insurance contracts. There are several sources of uncertainty that need to be considered in the estimation of the liabilities that the Group will ultimately be required to pay as claims. The valuation of life insurance contract liabilities is dependent on the valuation method adopted and key assumptions such as prevailing interest rates of government securities and estimates of mortality, disability, dread disease, expenses, lapse and surrenders based on GEH’s internal experience studies and publicly available data. The valuation of general insurance contract liabilities is dependent on estimates including the ultimate settlement cost of claims reported, and claims incurred but not yet reported. We reviewed GEH’s auditors’ working papers and involved our actuarial specialists in our discussions with GEH’s auditors. We independently assessed, through a review of procedures carried out by GEH’s auditors, that the valuation methodologies and assumptions relating to the measurement and estimation of insurance contract liabilities were reasonable. Based on the reports from GEH’s auditors and our review of GEH’s auditors’ working papers, we concluded that the valuation methods and assumptions used by the Group were reasonable, and the values of insurance contract liabilities were within an acceptable range of outcomes. Changes in the assumptions used in calculation of the valuation could result in a material impact to the carrying amount of insurance contract liabilities and the related movements in the income statement. Impairment of goodwill (Refer to Note 37 to the financial statements.) The key audit matter How the matter was addressed in our audit At 31 December 2017, the Group’s balance sheet included goodwill of $4.5 billion arising from a number of acquisitions. Goodwill is impaired if its carrying amount is not supported by the recoverable amount of the respective cash generating units (CGUs). The recoverable amounts are determined based on estimates that require significant judgement in application of methodologies, and assumptions. We assessed the appropriateness of management’s identification of the Group’s CGUs. We involved our valuation specialists to assess the methodologies applied and assumptions used for determining recoverable amounts. In respect of goodwill of banking CGUs amounting to $4.0 billion, the recoverable amounts were determined using the value-in-use method, based on estimated future cash flows for each CGU discounted at an appropriate discount rate. Significant management judgement included the expected future cash flows, the discount rate and terminal growth rate. In respect of the insurance CGU, the recoverable amount was estimated using the appraisal value method, based on the adjusted shareholders’ funds and the expected future profits generated by the portfolio of the business in force at the valuation date and the capacity to generate future profitable new business. Significant assumptions used in the assessment of these values included the discount rate and the investment return rates. 156 OCBC ANNUAL REPORT 2017 For the banking CGUs, we assessed management’s future cash flow projections for consistency with historical cash flows and business plans and investigated reasons for significant deviations. We challenged the key assumptions including discount rate and growth rate by comparing with external sources and economic metrics. We also reperformed calculations using the models. For the insurance CGU, we assessed management’s assumptions on discount rates and investment returns through our review of GEH’s auditors’ working papers on valuation of insurance contracts. We also performed sensitivity analysis on the impact of change in key assumptions to the appraisal value. Based on the results of our test procedures, the carrying amount of goodwill was supported by the recoverable amount of the respective CGUs.
