Level 3 Financial Assets and Liabilities Measured at Fair Value on a Recurring Basis, Roll Forward Table of Change in Balances

The following tables present the changes in fair value for Level 3 assets and liabilities measured at fair value on a recurring basis. The realized and unrealized gains and losses in the tables may include changes in fair value that were attributable to both observable and unobservable inputs. In the following tables, gains/(losses) on trading instruments are reported in “Principal transactions” and gains/(losses) on other investments are reported in “Other” revenues on our Consolidated Statements of Income and Comprehensive Income.

Year ended September 30, 2021 Level 3 instruments at fair value

	Trading assets		Derivative assets		Other investments				Derivative liabilities

The net unrealized gains included in earnings on our Level 3 private equity investments for the year ended September 30, 2021 primarily reflected the impact of continued improvement in market conditions and an improved outlook for certain of our investments. Of these gains, $24 million were attributable to noncontrolling interests, which are reflected as an offset in “Other” expenses on our Consolidated Statements of Income and Comprehensive Income.

Significant Assumptions Used in Valuation of Level 3 Financial Instruments

The following table presents the valuation techniques and significant unobservable inputs used in the valuation of certain of our private equity investments classified as level 3. These inputs represent those that a market participant would take into account when pricing these instruments. Weighted averages are calculated by weighting each input by the relative fair value of the related financial instrument. Certain investments are valued initially at transaction price and updated as other investment-specific events take place which indicate that a change in the carrying values of these investments is appropriate. Other investment-specific events include such events as our periodic review, significant transactions occur or new developments become known.

Recurring measurements $ in millions	Fair value at September 30, 2021		Valuation technique(s)	Unobservable input	Range (weighted-average)
Other investments - private equity investments (not measured at NAV)	$	75	Discounted cash flow, transaction price or other investment-specific events	Discount rate	25%
				Terminal earnings before interest, taxes, depreciation and amortization (“EBITDA”) multiple	10.0x
				Terminal year	2023 - 2035 (2024)
	Fair value at September 30, 2020
Other investments - private equity investments (not measured at NAV)	$	37	Discounted cash flow, transaction price or other investment-specific events	Discount rate	25%
				Terminal EBITDA multiple	9.0x

Fair Value Measurements, Nonrecurring

The following table presents assets measured at fair value on a nonrecurring basis along with the valuation techniques and significant unobservable inputs used in the valuation of the assets classified as level 3. These inputs represent those that a market participant would take into account when pricing these instruments. Weighted averages are calculated by weighting each input by the relative fair value of the related financial instrument.

$ in millions	Level 2		Level 3		Total fair value		Valuation technique(s)	Unobservable input	Range (weighted-average)
September 30, 2021
Bank loans:
Residential mortgage loans	$	3	$	11	$	14	Collateral or discounted cash flow (1)	Prepayment rate	7 yrs. - 12 yrs. (10.5 yrs.)
Corporate loans	$	—	$	49	$	49	Collateral or discounted cash flow (1)	Not meaningful (1)	Not meaningful (1)
Loans held for sale	$	29	$	—	$	29	N/A	N/A	N/A

Bank loans:
Residential mortgage loans	$	4	$	13	$	17	Collateral or discounted cash flow (1)	Prepayment rate	7 yrs. - 12 yrs. (10.6 yrs.)
Corporate loans	$	—	$	15	$	15	Collateral or discounted cash flow (1)	Not meaningful (1)	Not meaningful (1)
Loans held for sale	$	38	$	—	$	38	N/A	N/A	N/A
Other assets: other real estate owned	$	1	$	—	$	1	N/A	N/A	N/A

(1)    The valuation techniques used to estimate the fair values are based on collateral value less selling costs for the collateral-dependent loans and discounted cash flows for loans that are not collateral-dependent.

Carrying Amounts and Estimated Fair Values of Financial Instruments Not Recorded at Fair Value
