NOTES TO THE FINANCIAL STATEMENTS For the financial year ended 31 December 2017 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (continued) 2.9 INVESTMENT PROPERTY (continued) Investment property held under the Group’s life assurance fund is stated at fair value at the balance sheet date and collectively form an asset class which is an integral part of the overall investment strategy for the asset-liability management of the life assurance business. The fair value of the investment properties is determined based on objective valuations undertaken by independent valuers at the reporting date. Changes in the carrying value resulting from revaluation are recognised in the income statement of the life assurance fund. 2.10 GOODWILL AND INTANGIBLE ASSETS 2.10.1 Goodwill Goodwill on acquisition of subsidiaries represents the excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previously held equity interest over the fair value of the identifiable net assets acquired. Goodwill is stated at cost less impairment loss. Impairment test is carried out annually, or when there is indication that the goodwill may be impaired. Gains or losses on disposal of subsidiaries and associates include the carrying amount of goodwill relating to the entity sold. 2.10.2 Intangible assets Intangible assets are separately identifiable intangible items arising from acquisitions and are stated at cost less accumulated amortisation and impairment losses. Intangible assets with finite useful lives are amortised over their estimated useful lives. The estimated useful lives range from 10 to 20 years. The useful life of an intangible asset is reviewed at least at each financial year end. 2.11 NON-CURRENT ASSETS HELD FOR SALE Non-current assets that are expected to be recovered through sale rather than through continuing use are classified as held for sale. Immediately before classification as held for sale, the assets are measured in accordance with the Group’s accounting policies. Thereafter, the assets are generally measured at the lower of their carrying amount and fair value less cost to sell. 2.12 IMPAIRMENT OF ASSETS Financial assets The Group assesses at each balance sheet date whether there is objective evidence that a financial asset or a group of financial assets is impaired. 2.12.1 Loans and receivables/financial assets carried at amortised cost Loans are assessed for impairment on a loan-by-loan basis except for homogeneous loans below a certain materiality threshold, which are grouped together according to their risk characteristics and collectively assessed, taking into account the historical loss experience on such loans. A specific allowance is established when the present value of recoverable cash flows for a loan is lower than the carrying value 170 OCBC ANNUAL REPORT 2017 of the loan. Portfolio allowances are set aside for unimpaired loans based on portfolio and country risks, as well as industry practices. Specific allowances are written back to the income statement when the loans are no longer impaired or when the loss on loan is determined to be less than the amount of specific allowance previously made. Loans are written-off when recovery action has been instituted and the loss can be reasonably determined. 2.12.2 Other non-derivative financial assets Impairment of other non-derivative financial assets is calculated as the difference between the asset’s carrying value and the estimated recoverable amount. For equity investments classified as available-for-sale, when there is a significant or prolonged decline in the fair value of the asset below its cost, the cumulative loss (measured as the difference between the acquisition cost and the current fair value, less any impairment loss on that asset previously recognised in the income statement) is removed from the fair value reserve within equity and recognised in the income statement. Impairment losses on equity investments recognised in the income statement are not reversed through the income statement, until the investments are disposed of. For debt investments, reversal of an impairment loss that can be related objectively to an event occurring after the impairment loss was recognised, is recognised in the income statement. Other assets 2.12.3 Goodwill For the purpose of impairment testing, goodwill is allocated to each of the Group’s Cash Generating Units (“CGU”) expected to benefit from synergies of the business combination. The Group’s CGUs correspond with the business segments identified in the primary segment report. An impairment loss is recognised in the income statement when the carrying amount of the CGU, including the goodwill, exceeds the recoverable amount of the CGU. The CGU’s recoverable amount is the higher of its fair value less cost to sell and its value in use. Impairment loss on goodwill cannot be reversed in subsequent periods. 2.12.4 Investments in subsidiaries and associates Property, plant and equipment Investment property Intangible assets Investments in subsidiaries and associates, property, plant and equipment, investment property and intangible assets, are reviewed for impairment on the balance sheet date or whenever there is any indication that the carrying value of an asset may not be recoverable. If such an indication exists, the carrying value of the asset is written down to its recoverable amount (i.e. the higher of the fair value less cost to sell and the value in use). The impairment loss is recognised in the income statement, and is reversed only if there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognised. The carrying amount of an asset is increased to its revised recoverable amount, provided that this amount does not exceed the carrying value that would have been determined (net of amortisation or depreciation) had no impairment loss been recognised for the asset in prior years.
