Notes to the consolidated financial statements of Aegon N.V.  Note 2 156 Net fair value change of general account financial investments at fair value through profit or loss, other than derivatives Net fair value change of general account financial investments at fair value through profit or loss, other than derivatives include  fair value changes of financial assets carried at fair value through profit or loss. The net gains and losses do not include interest or  dividend income. Gains and losses on financial investments include realized gains and losses on general account financial assets, other than those  classified as at fair value through profit or loss.  All changes in fair value are recognized in the income statement, unless the derivative has been designated as a hedging instrument  in a cash flow hedge or a hedge of a net investment in a foreign operation. Fair value movements of fair value hedge instruments  are offset by the fair value movements of the hedged item, and the resulting hedge ineffectiveness, if any, is included in this line. In  addition, the fair value movements of bifurcated embedded derivatives are included in this line. Net fair value change on for account of policyholder financial assets at fair value through profit or loss includes fair value movements  of investments held for account of policyholders (refer to note 2.8). The net fair value change does not include interest or  dividend income. In addition, results from financial transactions include gains/losses on real estate (general account and account of policyholders),  net foreign currency gains/(losses) and net fair value change on borrowings and other financial liabilities and realized gains on  repurchased debt. Impairment charges and reversals include impairments and reversals on investments in financial assets, impairments and reversals on  the valuation of insurance assets and liabilities and other non-financial assets and receivables. Refer to note 15.  Interest charges and related fees includes interest expense on trust pass-through securities and other borrowings. Interest expense  on trust pass-through securities and other borrowings carried at amortized cost is recognized in profit or loss using the effective  interest method. Arrangements that do not take the form of a lease but convey a right to use an asset in return for a payment are assessed at inception  to determine whether they are, or contain, a lease. This involves an assessment of whether fulfillment of the arrangement is dependent  on the use of a specific asset and whether the purchaser (lessee) has the right to control the use of the underlying asset. Payments made under operating leases, where the Group is the lessee, are charged to the income statement on a straight line basis  over the period of the lease. Leases that do not transfer substantially all the risks and rewards of ownership are classified as operating leases.  Where the Group is the lessor under an operating lease, the assets subject to the operating lease arrangement are presented in  the statement of financial position according to the nature of the asset. Income from these leases are recognized in the income  statement on a straight line basis over the lease term, unless another systematic basis is more representative of the time pattern in  which use benefit derived from the leased asset is diminished. The financial statements are adjusted to reflect events that occurred between the balance sheet date and the date when the financial  statements are authorized for issue, provided they give evidence of conditions that existed at the balance sheet date. Events that are indicative of conditions that arose after the balance sheet date are disclosed, but do not result in an adjustment of  the financial statements themselves.
