(a) "Collateralized mortgage obligations” and “Other mortgage-back securities” were renamed to “Agency residential collateralized mortgage obligations” and “Agency residential mortgage-backed securities”, respectively, as of December 31, 2016. There was no reclassification of previously reported balances.

(b) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the consolidated balance sheet.

(c) Netting adjustments represent the amounts recorded to convert our derivative assets and liabilities from a gross basis to a net basis in accordance with applicable accounting guidance. The net basis takes into account the impact of bilateral collateral and master netting agreements that allow us to settle all derivative contracts with a single counterparty on a net basis and to offset the net derivative position with the related cash collateral. Total derivative assets and liabilities include these netting adjustments.

Change in Fair Values of Level 3 Financial Instruments

The following table shows the change in the fair values of our Level 3 financial instruments for the years ended December 31, 2016, and December 31, 2015. We mitigate the credit risk, interest rate risk, and risk of loss related to many of these Level 3 instruments by using securities and derivative positions classified as Level 1 or Level 2. Level 1 and Level 2 instruments are not included in the following table. Therefore, the gains or losses shown do not include the impact of our risk management activities.

(d) Realized and unrealized gains and losses on derivative instruments are reported in “corporate services income” and “other income” on the income statement.

(e) Our policy is to recognize transfers into and transfers out of Level 3 as of the end of the reporting period.

(f) Certain derivatives previously classified as Level 2 were transferred to Level 3 because Level 3 unobservable inputs became significant. Certain derivatives previously classified as Level 3 were transferred to Level 2 because Level 3 unobservable inputs became less significant.

(g) There were no issuances for the years ended December 31, 2016, and December 31, 2015.

Valuation Methods and Assumptions

(a) Fair value equals or approximates carrying amount. The fair value of deposits with no stated maturity does not take into consideration the value ascribed to core deposit intangibles.

(b) Information pertaining to our methodology for measuring the fair values of these assets and liabilities is included in the sections entitled “Qualitative Disclosures of Valuation Techniques” and “Assets Measured at Fair Value on a Nonrecurring Basis” in this Note.

(c) Fair values of held-to-maturity securities are determined by using models that are based on security-specific details, as well as relevant industry and economic factors. The most significant of these inputs are quoted market prices, interest rate spreads on relevant benchmark securities, and certain prepayment assumptions. We review the valuations derived from the models to ensure they are reasonable and consistent with the values placed on similar securities traded in the secondary markets.

(d) The fair value of loans is based on the present value of the expected cash flows. The projected cash flows are based on the contractual terms of the loans, adjusted for prepayments and use of a discount rate based on the relative risk of the cash flows, taking into account the loan type, maturity of the loan, liquidity risk, servicing costs, and a required return on debt and capital. In addition, an incremental liquidity discount is applied to certain loans, using historical sales of loans during periods of similar economic conditions as a benchmark. The fair value of loans includes lease financing receivables at their aggregate carrying amount, which is equivalent to their fair value.

(e) Fair values of time deposits and long-term debt are based on discounted cash flows utilizing relevant market inputs.

(f) Netting adjustments represent the amounts recorded to convert our derivative assets and liabilities from a gross basis to a net basis in accordance with applicable accounting guidance. The net basis takes into account the impact of bilateral collateral and master netting agreements that allow us to settle all derivative contracts with a single counterparty on a net basis and to offset the net derivative position with the related cash collateral. Total derivative assets and liabilities include these netting adjustments.

Fair Value of Direct and Indirect Investments, Related Unfunded Commitments and Financial Support Provided

The following table presents the fair value of our indirect investments and related unfunded commitments at December 31, 2016. We did not provide any financial support to investees related to our direct and indirect investments for the years ended December 31, 2016, and December 31, 2015.

INVESTMENT TYPE
Indirect investments
Passive funds (a)	$	6	$	2
Total	$	6	$	2

(a) We invest in passive funds, which are multi-investor private equity funds. These investments can never be redeemed. Instead, distributions are received through the liquidation of the underlying investments in the funds. Some funds have no restrictions on sale, while others require investors to remain in the fund until maturity. The funds will be liquidated over a period of one to three years. The purpose of KREEC’s funding is to allow funds to make additional investments and keep a certain market value threshold in the funds. KREEC is obligated to provide financial support, as all investors are required, to fund based on their ownership percentage, as noted in the Limited Partnership Agreements.

Fair Value of Direct and Indirect Investments, Related Unfunded Commitments and Financial Support Provided

The following table presents the fair value of our direct and indirect principal investments and related unfunded commitments at December 31, 2016, as well as financial support provided for the years ended December 31, 2016, and December 31, 2015.

Indirect investments (b)	158		$	37	$	6	—		$	8	—
Total	$	185	$	37	$	6	$	13	$	8	$	2

(a) Our direct investments consist of equity and debt investments directly in independent business enterprises. Operations of the business enterprises are handled by management of the portfolio company. The purpose of funding these enterprises is to provide financial support for business development and acquisition strategies. We infuse equity capital based on an initial contractual cash contribution and later from additional requests on behalf of the companies’ management.

(b) Our indirect investments consist of buyout funds, venture capital funds, and fund of funds. These investments are generally not redeemable. Instead, distributions are received through the liquidation of the underlying investments of the fund. An investment in any one of these funds typically can be sold only with the approval of the fund’s general partners. We estimate that the underlying investments of the funds will be liquidated over a period of oneto eight years. The purpose of funding our capital commitments to these investments is to allow the funds to make additional follow-on investments and pay fund expenses until the fund dissolves. We, and all other investors in the fund, are obligated to fund the full amount of our respective capital commitments to the fund based on our and their respective ownership percentages, as noted in the applicable Limited Partnership Agreement.
