Financial Instruments Designated at Fair Value
Most of our structured note liabilities included in deposits have been designated at fair value through profit or loss which aligns the accounting result with the way the portfolio is managed. The fair value and notional amount due at contractual maturity of these structured notes as at April 30, 2019 were $16,142 million and $15,701 million, respectively ($14,186 million and $14,548 million, respectively, as at October 31, 2018). The change in fair value of these structured notes was recorded as a decrease of $365 million and a decrease of $765 million innon-interest revenue, trading revenue and a decrease of $121 million and a decrease of $14 million recorded in other comprehensive income related to changes in our credit spread, respectively, for the three and six months ended April 30, 2019 (an increase of $197 million and a decrease of $72 million recorded innon-interest revenue, trading revenue, and an increase of $49 million and a decrease of $41 million recorded in other comprehensive income related to changes in our own credit spread, respectively, for the three and six months ended April 30, 2018). The impact of economic hedges used to manage the exposure is also recorded innon-interest revenue, trading revenue. The impact of changes in our credit spread is measured based on movements in our credit spread quarter over quarter.
The cumulative change in fair value related to changes in our own credit spread that has been recognized since the notes were designated at fair value to April 30, 2019 was an unrealized loss of $345 million, of this an unrealized loss of $269 million was recorded in other comprehensive income, with an unrealized loss of $76 million recorded through the Consolidated Statement of Income prior to the adoption of IFRS 9 own credit provision in 2015.
We designate certain securities held by our insurance subsidiaries that support our insurance liabilities at fair value through profit or loss since the actuarial calculation of insurance liabilities is based on the fair value of the investments supporting them. This designation aligns the accounting result with the way the portfolio is managed on a fair value basis. The change in fair value of the assets is recorded innon-interest revenue, insurance revenue and the change in fair value of the liabilities is recorded in insurance claims, commissions and changes in policy benefit liabilities. The fair value of these investments as at April 30, 2019 of $10,007 million ($8,783 million as at October 31, 2018) is recorded in securities in our Consolidated Balance Sheet. The impact of recording these investments at fair value through profit or loss was an increase of $337 million and $593 million innon-interest revenue, insurance revenue, respectively, for the three and six months ended April 30, 2019 (a decrease of $124 million and $134 million, respectively, for the three and six months ended April 30, 2018).
We designate the obligation related to certain investment contracts in our insurance business at fair value through profit or loss, which eliminates a measurement inconsistency that would otherwise arise from measuring the investment contract liabilities and offsetting changes in the fair value of the investments supporting them on a different basis. The fair value of these investment contract liabilities as at April 30, 2019 of $952 million ($800 million as at October 31, 2018) is recorded in other liabilities in our Consolidated Balance Sheet. The change in fair value of these investment contract liabilities resulted in an increase of $24 million and an increase of $61 million in insurance claims, commissions, and changes in policy benefit liabilities, respectively, for the three and six months ended April 30, 2019 (an increase of $1 million and a decrease of $13 million, respectively, for the three and six months ended April 30, 2018). For the three and six months ended April 30, 2019, a decrease of $13 million and a decrease of $12 million, respectively, was recorded in other comprehensive income related to changes in our own credit spread (an increase of $8 million and a decrease of $2 million, respectively, for the three and six months ended April 30, 2018). Changes in the fair value of investments backing these investment contract liabilities are recorded innon-interest revenue, insurance revenue. The impact of changes in our credit spread is measured based on movements in our credit spread quarter over quarter.
Fair Value Hierarchy
We use a fair value hierarchy to categorize financial instruments according to the inputs we use in valuation techniques to measure fair value.
Valuation Techniques and Significant Inputs
We determine the fair value of publicly traded fixed maturity and equity securities using quoted prices in active markets (Level 1) when these are available. We exercise a degree of judgement in determining whether the market from which a quoted price has been obtained is active. When quoted prices in active markets are not available, we determine the fair value of financial instruments using models such as discounted cash flows with observable market data for inputs such as yield and prepayment rates or broker quotes and other third-party vendor quotes (Level 2). Fair value may also be determined using models where significant market inputs are not observable due to inactive markets or minimal market activity (Level 3). We maximize the use of market inputs to the extent possible.
Our Level 2 trading and FVTPL securities are primarily valued using discounted cash flow models with observable spreads or broker quotes. The fair value of Level 2 FVOCI securities is determined using discounted cash flow models with observable spreads or third-party vendor quotes. Level 2 structured note liabilities are valued using models with observable market information. Level 2 derivative assets and liabilities are valued using industry standard models and observable market information.
