THE GOLDMAN SACHS GROUP, INC.  AND SUBSIDIARIES Notes to Consolidated Financial Statements Market-Making.
As a market maker, the firm enters into derivative transactions to provide liquidity to clients and to facilitate the transfer and hedging of their risks.
In this role, the firm typically acts as principal and is required to commit capital to provide execution, and maintains inventory in response to, or in anticipation of, client demand.
Risk Management.
The firm also enters into derivatives to actively manage risk exposures that arise from its marketmaking and investing and lending activities in derivative and cash instruments.
The firm’s holdings and exposures are hedged, in many cases, on either a portfolio or riskspecific basis, as opposed to an instrument-by-instrument basis.
The offsetting impact of this economic hedging is reflected in the same business segment as the related revenues.
In addition, the firm may enter into derivatives designated as hedges under U. S.  GAAP.
These derivatives are used to manage interest rate exposure in certain fixedrate unsecured long-term and short-term borrowings, and deposits, and to manage foreign currency exposure on the net investment in certain non-U.
S.  operations.
The firm enters into various types of derivatives, including: ‰ Futures and Forwards.
Contracts that commit counterparties to purchase or sell financial instruments, commodities or currencies in the future.
‰ Swaps.
Contracts that require counterparties to exchange cash flows such as currency or interest payment streams.
The amounts exchanged are based on the specific terms of the contract with reference to specified rates, financial instruments, commodities, currencies or indices.
‰ Options.
Contracts in which the option purchaser has the right, but not the obligation, to purchase from or sell to the option writer financial instruments, commodities or currencies within a defined time period for a specified price.
Derivatives are reported on a net-by-counterparty basis (i. e. , the net payable or receivable for derivative assets and liabilities for a given counterparty) when a legal right of setoff exists under an enforceable netting agreement (counterparty netting).
Derivatives are accounted for at fair value, net of cash collateral received or posted under enforceable credit support agreements (cash collateral netting).
Derivative assets and liabilities are included in financial instruments owned and financial instruments sold, but not yet purchased, respectively.
Realized and unrealized gains and losses on derivatives not designated as hedges under ASC 815 are included in market making and other principal transactions in Note 4.
The tables below present the gross fair value and the notional amounts of derivative contracts by major product type, the amounts of counterparty and cash collateral netting in the consolidated statements of financial condition, as well as cash and securities collateral posted and received under enforceable credit support agreements that do not meet the criteria for netting under U. S.  GAAP.
## Table 0 ##
THE GOLDMAN SACHS GROUP, INC.  AND SUBSIDIARIES Notes to Consolidated Financial Statements Transfers into level 3 of other financial liabilities during 2016 primarily reflected transfers of certain hybrid financial instruments included in unsecured short-term and long-term borrowings from level 2, principally due to reduced transparency of certain inputs, including correlation and volatility inputs used to value these instruments.
Transfers out of level 3 of other financial liabilities during 2016 primarily reflected transfers of certain hybrid financial instruments included in unsecured short-term and long-term borrowings to level 2, principally due to increased transparency of correlation and volatility inputs used to value these instruments.
Gains and Losses on Financial Assets and Financial Liabilities Accounted for at Fair Value Under the Fair Value Option The table below presents the gains and losses recognized in earnings as a result of the firm electing to apply the fair value option to certain financial assets and financial liabilities.
## Table 1 ##
In the table above: ‰ Gains/(losses) are included in market making and other principal transactions.
‰ Gains/(losses) exclude contractual interest, which is included in interest income and interest expense, for all instruments other than hybrid financial instruments.
See Note 23 for further information about interest income and interest expense.
‰ Gains/(losses) included in unsecured short-term borrowings are substantially all related to the embedded derivative component of hybrid financial instruments for 2017, 2016 and 2015.
Gains/(losses) included in unsecured long-term borrowings are primarily related to the embedded derivative component of hybrid financial instruments for 2017, 2016 and 2015.
These gains and losses would have been recognized under other U. S.  GAAP even if the firm had not elected to account for the entire hybrid financial instrument at fair value.
‰ Other liabilities and accrued expenses includes gains/ (losses) on certain subordinated liabilities of consolidated VIEs.
‰ Other primarily consists of gains/(losses) on receivables from customers and counterparties, deposits and other secured financings.
Excluding the gains and losses on the instruments accounted for under the fair value option described above, market making and other principal transactions primarily represent gains and losses on financial instruments owned and financial instruments sold, but not yet purchased.
Loans and Lending Commitments The table below presents the difference between the aggregate fair value and the aggregate contractual principal amount for loans and long-term receivables for which the fair value option was elected.
## Table 2 ##
In the table above, the aggregate contractual principal amount of loans on nonaccrual status and/or more than 90 days past due (which excludes loans carried at zero fair value and considered uncollectible) exceeds the related fair value primarily because the firm regularly purchases loans, such as distressed loans, at values significantly below the contractual principal amounts.
As of December 2017 and December 2016, the fair value of unfunded lending commitments for which the fair value option was elected was a liability of $31 million and $80 million, respectively, and the related total contractual amount of these lending commitments was $9.94 billion and $7.19 billion, respectively.
See Note 18 for further information about lending commitments.
Long-Term Debt Instruments The difference between the aggregate contractual principal amount and the related fair value of long-term other secured financings for which the fair value option was elected was not material as of December 2017, and the aggregate contractual principal amount exceeded the related fair value by $361 million as of December 2016.
The aggregate contractual principal amount of unsecured long-term borrowings for which the fair value option was elected exceeded the related fair value by $1.69 billion and $1.56 billion as of December 2017 and December 2016, respectively.
The amounts above include both principaland non-principal-protected long-term borrowings.
THE GOLDMAN SACHS GROUP, INC.  AND SUBSIDIARIES Notes to Consolidated Financial Statements The firm is unable to develop an estimate of the maximum payout under these guarantees and indemnifications.
However, management believes that it is unlikely the firm will have to make any material payments under these arrangements, and no material liabilities related to these guarantees and indemnifications have been recognized in the consolidated statements of financial condition as of both December 2017 and December 2016.
Other Representations, Warranties and Indemnifications.
The firm provides representations and warranties to counterparties in connection with a variety of commercial transactions and occasionally indemnifies them against potential losses caused by the breach of those representations and warranties.
The firm may also provide indemnifications protecting against changes in or adverse application of certain U. S.  tax laws in connection with ordinary-course transactions such as securities issuances, borrowings or derivatives.
In addition, the firm may provide indemnifications to some counterparties to protect them in the event additional taxes are owed or payments are withheld, due either to a change in or an adverse application of certain non-U.
S.  tax laws.
These indemnifications generally are standard contractual terms and are entered into in the ordinary course of business.
Generally, there are no stated or notional amounts included in these indemnifications, and the contingencies triggering the obligation to indemnify are not expected to occur.
The firm is unable to develop an estimate of the maximum payout under these guarantees and indemnifications.
However, management believes that it is unlikely the firm will have to make any material payments under these arrangements, and no material liabilities related to these arrangements have been recognized in the consolidated statements of financial condition as of both December 2017 and December 2016.
