Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives and Other Financial Instruments | Q. Derivatives and Other Financial Instruments Fair Value Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below:
| • |  | Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
| • |  | Level 2 - Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly, including quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (e.g., interest rates); and inputs that are derived principally from or corroborated by observable market data by correlation or other means.
| • |  | Level 3 - Inputs that are both significant to the fair value measurement and unobservable.
Derivatives Arconic is exposed to certain risks relating to its ongoing business operations, including financial, market, political, and economic risks. The following discussion provides information regarding Arconic’s exposure to the risks of changing commodity prices, interest rates, and foreign currency exchange rates. Arconic’s commodity and derivative activities are subject to the management, direction, and control of the Strategic Risk Management Committee (SRMC), which is composed of the chief executive officer, the chief financial officer, and other officers and employees that the chief executive officer selects. The SRMC meets on a periodic basis to review derivative positions and strategy and reports to Arconic’s Board of Directors on the scope of its activities. The aluminum, energy, interest rate, and foreign exchange contracts are held for purposes other than trading. They are used primarily to mitigate uncertainty and volatility, and to cover underlying exposures. Arconic is not involved in trading activities for energy, weather derivatives, or other nonexchange commodity trading activities. A number of Arconic’s aluminum, energy, and foreign exchange contracts are classified as Level 1 and an interest rate contract is classified as Level 2 under the fair value hierarchy. These energy, foreign exchange, and interest rate contracts are not material to Arconic’s Consolidated Financial Statements for all periods presented. For the aluminum contracts classified as Level 1, the total fair value of derivatives recorded as assets and liabilities was $11 and $9, respectively, at September 30, 2016 and $8 and $58, respectively, at December 31, 2015. These contracts were entered into to either hedge forecasted sales or purchases of aluminum in order to manage the associated aluminum price risk. Certain of these contracts are designated as hedging instruments, either fair value or cash flow, and the remaining are not designated as such. Combined, Arconic recognized a net gain of $1 and $4 in the 2016 third quarter and nine-month period, respectively, and a net loss of $7 and a net gain of $34 in the 2015 third quarter and nine-month period, respectively, in Sales on the accompanying Statement of Consolidated Operations related to these aluminum contracts. Arconic recognized a net gain of $1 for both the 2016 third quarter and nine-month period in Other Comprehensive (Loss) Income. No net gain or loss was recognized in the 2015 third quarter and nine-month period in Other Comprehensive (Loss) Income. In addition to the Level 1 and 2 derivative instruments described above, Arconic has ten derivative instruments classified as Level 3 under the fair value hierarchy. These instruments are composed of eight embedded aluminum derivatives, an energy contract, and an embedded credit derivative, all of which relate to energy supply contracts associated with nine smelters and three refineries. Five of the embedded aluminum derivatives and the energy contract were designated as cash flow hedging instruments and three of the embedded aluminum derivatives and the embedded credit derivative were not designated as hedging instruments. The following section describes the valuation methodologies used by Arconic to measure its Level 3 derivative instruments at fair value. Derivative instruments classified as Level 3 in the fair value hierarchy represent those in which management has used at least one significant unobservable input in the valuation model. Arconic uses a discounted cash flow model to fair value all Level 3 derivative instruments. Where appropriate, the description below includes the key inputs to those models and any significant assumptions. These valuation models are reviewed and tested at least on an annual basis. Inputs in the valuation models for Level 3 derivative instruments are composed of the following: (i) quoted market prices (e.g., aluminum prices on the 10-year London Metal Exchange (LME) forward curve and energy prices), (ii) significant other observable inputs (e.g., information concerning time premiums and volatilities for certain option type embedded derivatives and regional premiums for aluminum contracts), and (iii) unobservable inputs (e.g., aluminum and energy prices beyond those quoted in the market). For periods beyond the term of quoted market prices for aluminum, Arconic estimates the price of aluminum by extrapolating the 10-year LME forward curve. Additionally, for periods beyond the term of quoted market prices for energy, management has developed a forward curve based on independent consultant market research. Where appropriate, valuations are adjusted for various factors such as liquidity, bid/offer spreads, and credit considerations. Such adjustments are generally based on available market evidence (Level 2). In the absence of such evidence, management’s best estimate is used (Level 3). If a significant input that is unobservable in one period becomes observable in a subsequent period, the related asset or liability would be transferred to the appropriate classification (Level 1 or 2) in the period of such change (there were no such transfers in the periods presented). Arconic has two power contracts, each of which contain an embedded derivative that indexes the price of power to the LME price of aluminum. Additionally, Arconic has three power contracts, each of which contain an embedded derivative that indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivatives in these five power contracts are primarily valued using observable market prices; however, due to the length of the contracts, the valuation models also require management to estimate the long-term price of aluminum based upon an extrapolation of the 10-year LME forward curve. Additionally, for three of these contracts, management also estimates the Midwest premium, generally, for the next twelve months based on recent transactions and then holds the premium estimated in that twelfth month constant for the remaining duration of the contract. Significant increases or decreases in the actual LME beyond 10 years and/or the Midwest premium would result in a higher or lower fair value measurement. An increase in actual LME price and/or the Midwest premium over the inputs used in the valuation models will result in a higher cost of power and a corresponding decrease to the derivative asset or increase to the derivative liability. The embedded derivatives have been designated as cash flow hedges of forward sales of aluminum. Unrealized gains and losses were included in Other comprehensive (loss) income on the accompanying Consolidated Balance Sheet while realized gains and losses were included in Sales on the accompanying Statement of Consolidated Operations. Also, Arconic has a power contract (which expired in September 2016 – see below) separate from above that contains an LME-linked embedded derivative. Prior to its expiration, the embedded derivative was valued using the probability and interrelationship of future LME prices, Australian dollar to U.S. dollar exchange rates, and the U.S. consumer price index. Significant increases or decreases in the LME price would result in a higher or lower fair value measurement. An increase in actual LME price over the inputs used in the valuation model would result in a higher cost of power and a corresponding decrease to the derivative asset. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other income, net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract. At the time this derivative asset was recognized, an equivalent amount was recognized as a deferred credit in Other noncurrent liabilities and deferred credits on the accompanying Consolidated Balance Sheet. This deferred credit was recognized in Other income, net on the accompanying Statement of Consolidated Operations as power was received over the life of the contract. Additionally, Arconic has a natural gas supply contract, which has an LME-linked ceiling. This embedded derivative is valued using probabilities of future LME aluminum prices and the price of Brent crude oil (priced on Platts), including the interrelationships between the two commodities subject to the ceiling. Any change in the interrelationship would result in a higher or lower fair value measurement. An LME ceiling was embedded into the contract price to protect against an increase in the price of oil without a corresponding increase in the price of LME. An increase in oil prices with no similar increase in the LME price would limit the increase of the price paid for natural gas. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses from the embedded derivative were included in Other income, net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as gas purchases were made under the contract. In the second quarter of 2016, Arconic and the related counterparty elected to modify the pricing of an existing power contract for a smelter in the United States. This amendment contains an embedded derivative that indexes the price of power to the LME price of aluminum plus the Midwest premium. The embedded derivative is valued using the interrelationship of future metal prices (LME base plus Midwest premium) and the amount of megawatt hours of energy needed to produce the forecasted metric tons of aluminum at the smelter. Significant increases or decreases in the metal price would result in a higher or lower fair value measurement. An increase in actual metal price over the inputs used in the valuation model will result in a higher cost of power and a corresponding increase to the derivative liability. Management elected not to qualify the embedded derivative for hedge accounting treatment. Unrealized gains and losses from the embedded derivative will be included in Other income, net on the accompanying Statement of Consolidated Operations while realized gains and losses will be included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases are made under the contract. At the time this derivative liability was recognized, an equivalent amount was recognized as a deferred charge in Other noncurrent assets on the accompanying Consolidated Balance Sheet. This deferred charge will be recognized in Other income, net on the accompanying Statement of Consolidated Operations as power is received over the life of the contract. Furthermore, Arconic has a power contract, which contains an embedded derivative that indexes the difference between the long-term debt ratings of Arconic and the counterparty from any of the three major credit rating agencies. Management uses market prices, historical relationships, and forecast services to determine fair value. Significant increases or decreases in any of these inputs would result in a lower or higher fair value measurement. A wider credit spread between Arconic and the counterparty would result in a higher cost of power and a corresponding increase in the derivative liability. This embedded derivative did not qualify for hedge accounting treatment. Unrealized gains and losses were included in Other income, net on the accompanying Statement of Consolidated Operations while realized gains and losses were included in Cost of goods sold on the accompanying Statement of Consolidated Operations as electricity purchases were made under the contract. Finally, Arconic has a derivative contract that hedges the anticipated power requirements at one of its smelters that began when the previous power contract expired in September 2016 (see above). Beyond the term where market information is available, management developed a forward curve, for valuation purposes, based on independent consultant market research. Significant increases or decreases in the power market may result in a higher or lower fair value measurement. Lower prices in the power market would cause a decrease in the derivative asset. The derivative contract has been designated as a cash flow hedge of future purchases of electricity. Unrealized gains and losses on this contract were recorded in Other comprehensive (loss) income on the accompanying Consolidated Balance Sheet, while realized gains and losses will be recorded in Cost of goods sold as electricity purchases are made under the power contract. In August 2016, Arconic gave the required notice to terminate this derivative contract one year from the date of notification. As a result, Arconic decreased both the related derivative asset recorded in Other noncurrent assets and the unrealized gain recorded in Accumulated other comprehensive loss by $83, which related to the August 2017 through 2036 timeframe, resulting in no impact to Arconic’s earnings.

Derivatives Designated As Hedging Instruments – Cash Flow Hedges For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of unrealized gains or losses on the derivative is reported as a component of other comprehensive income (OCI). Realized gains or losses on the derivative are reclassified from OCI into earnings in the same period or periods during which the hedged transaction impacts earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized directly in earnings immediately. Arconic has five Level 3 embedded aluminum derivatives and one Level 3 energy contract that have been designated as cash flow hedges as follows. Embedded aluminum derivatives. Arconic has entered into energy supply contracts that contain pricing provisions related to the LME aluminum price. The LME-linked pricing features are considered embedded derivatives. Five of these embedded derivatives have been designated as cash flow hedges of forward sales of aluminum. At September 30, 2016 and December 31, 2015, these embedded aluminum derivatives hedge forecasted aluminum sales of 3,521 kmt and 3,307 kmt, respectively. Arconic recognized a net unrealized loss of $462 and $830 in the 2016 third quarter and nine-month period, respectively, and a net unrealized gain of $301 and $819 in the 2015 third quarter and nine-month period, respectively, in Other comprehensive (loss) income related to these five derivative instruments. Additionally, Arconic reclassified a realized gain of $1 and a realized loss of $4 in the 2016 third quarter and nine-month period, respectively, and a realized loss of $1 and $25 in the 2015 third quarter and nine-month period, respectively, from Accumulated other comprehensive loss to Sales. Assuming market rates remain constant with the rates at September 30, 2016, a realized gain of $23 is expected to be recognized in Sales over the next 12 months. Also, Arconic recognized a gain of less than $1 in the 2016 nine-month period (no such gain was recognized in the 2016 third quarter) and a gain of less than $1 and $2 in the 2015 third quarter and nine-month period, respectively, in Other income, net related to the amount excluded from the assessment of hedge effectiveness. There was no ineffectiveness related to these five derivative instruments in the 2016 third quarter and nine-month period and the 2015 third quarter and nine-month period. Energy contract. Arconic has a derivative contract that hedges the anticipated power requirements at one of its smelters that became effective when the existing power contract expired in September 2016. In August 2016, Arconic elected to terminate most of the remaining term of this derivative contract (see above). At September 30, 2016 and December 31, 2015, this energy contract hedges forecasted electricity purchases of 2,130,122 and 59,409,328 megawatt hours, respectively. Arconic recognized an unrealized gain of $49 and $88 in the 2016 third quarter and nine-month period, respectively, and an unrealized gain of $3 and an unrealized loss of $8 in the 2015 third quarter and nine-month period, respectively, in Other comprehensive (loss) income. Additionally, Arconic recognized a gain of $3 in Other income, net related to hedge ineffectiveness in the 2016 nine-month period. There was no ineffectiveness related to the energy contract in the 2016 third quarter and the 2015 third quarter and nine-month period. Derivatives Not Designated As Hedging Instruments Arconic has three Level 3 embedded aluminum derivatives and one Level 3 embedded credit derivative that do not qualify for hedge accounting treatment. As such, gains and losses related to the changes in fair value of these instruments are recorded directly in earnings. In the third quarter of 2016 and 2015, Arconic recognized a gain of $1 and a loss of $17, respectively, in Other income, net, of which a loss of $7 and $4, respectively, related to the embedded aluminum derivatives and a gain of $8 and a loss of $13, respectively, related to the embedded credit derivative. In the nine-month period of 2016 and 2015, Arconic recognized a loss of $8 and $19, respectively, in Other income, net, of which a loss of $15 and $5, respectively, related to the embedded aluminum derivatives and a gain of $7 and a loss of $14, respectively, related to the embedded credit derivative. Material Limitations The disclosures with respect to commodity prices, interest rates, and foreign currency exchange risk do not take into account the underlying commitments or anticipated transactions. If the underlying items were included in the analysis, the gains or losses on the futures contracts may be offset. Actual results will be determined by a number of factors that are not under Arconic’s control and could vary significantly from those factors disclosed. Arconic is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to its hedged customers’ commitments. Although nonperformance is possible, Arconic does not anticipate nonperformance by any of these parties. Contracts are with creditworthy counterparties and are further supported by cash, treasury bills, or irrevocable letters of credit issued by carefully chosen banks. In addition, various master netting arrangements are in place with counterparties to facilitate settlement of gains and losses on these contracts. Other Financial Instruments The carrying values and fair values of Arconic’s other financial instruments were as follows:
