Derivative Instruments and Hedging Activities Disclosure [Abstract]  
Derivative Instruments  DERIVATIVE INSTRUMENTS We have entered into the following derivative instruments that are reported at fair value:
We recognize our derivative instruments as either assets or liabilities and measure those instruments at fair value. None of our derivative instruments are designated as cash flow hedging instruments, and changes in fair value are recorded within our Consolidated Statements of Operations to the extent not utilized for the commissioning process.
The following table shows the fair value of our derivative instruments that are required to be measured at fair value on a recurring basis as of March 31, 2019 and December 31, 2018, which are classified as derivative assets, noncurrent derivative assets, derivative liabilities or noncurrent derivative liabilities in our Consolidated Balance Sheets (in millions).
There have been no changes to our evaluation of and accounting for our derivative positions during the three months ended March 31, 2019.
We value our Interest Rate Derivatives using an incomebased approach utilizing observable inputs to the valuation model including interest rate curves, risk adjusted discount rates, credit spreads and other relevant data. We value our LNG Trading Derivatives and our Liquefaction Supply Derivatives using a marketbased approach incorporating present value techniques, as needed, using observable commodity price curves, when available, and other relevant data. We value our FX Derivatives with a market approach using observable FX rates and other relevant data.
The fair value of our Physical Liquefaction Supply Derivatives is predominantly driven by market commodity basis prices and, as applicable to our natural gas supply contracts, our assessment of the associated conditions precedent, including evaluating whether the respective market is available as pipeline infrastructure is developed. Upon the satisfaction of conditions precedent, including completion and placement into service of relevant pipeline infrastructure to accommodate marketable physical gas flow, we recognize a gain or loss based on the fair value of the respective natural gas supply contracts.
We include a portion of our Physical Liquefaction Supply Derivatives as Level 3 within the valuation hierarchy as the fair value is developed through the use of internal models which may be impacted by inputs that are unobservable in the marketplace. The curves used to generate the fair value of our Physical Liquefaction Supply Derivatives are based on basis adjustments applied to forward curves for a liquid trading point. In addition, there may be observable liquid market basis information in the near term, but terms of a Physical Liquefaction Supply Derivatives contract may exceed the period for which such information is available, resulting in a Level 3 classification. In these instances, the fair value of the contract incorporates extrapolation assumptions made in the determination of the market basis price for future delivery periods in which applicable commodity basis prices were either not observable or lacked corroborative market data. As of March 31, 2019 and December 31, 2018, some of our Physical Liquefaction Supply Derivatives existed within markets for which the pipeline infrastructure is under development to accommodate marketable physical gas flow.
The Level 3 fair value measurements of natural gas positions within our Physical Liquefaction Supply Derivatives could be materially impacted by a significant change in certain natural gas market basis spreads due to the contractual notional amount represented by our Level 3 positions, which is a substantial portion of our overall Physical Liquefaction Supply Derivatives portfolio. The following table includes quantitative information for the unobservable inputs for our Level 3 Physical Liquefaction Supply Derivatives as of March 31, 2019:
The following table shows the changes in the fair value of our Level 3 Physical Liquefaction Supply Derivatives during the three months ended March 31, 2019 and 2018 (in millions):
Derivative assets and liabilities arising from our derivative contracts with the same counterparty are reported on a net basis, as all counterparty derivative contracts provide for net settlement. The use of derivative instruments exposes us to counterparty credit risk, or the risk that a counterparty will be unable to meet its commitments in instances when our derivative instruments are in an asset position. Additionally, we evaluate our own ability to meet our commitments in instances where our derivative instruments are in a liability position. Our derivative instruments are subject to contractual provisions which provide for the unconditional right of setoff for all derivative assets and liabilities with a given counterparty in the event of default.
Interest Rate Derivatives
During the three months ended March 31, 2019, there were no changes to the terms of the interest rate swaps (“CCH Interest Rate Derivatives”) entered into by CCH to protect against volatility of future cash flows and hedge a portion of the variable interest payments on its credit facility (the “CCH Credit Facility”).
Cheniere Partners previously had interest rate swaps (“CQP Interest Rate Derivatives”) to hedge a portion of the variable interest payments on its CQP Credit Facilities, which were terminated in October 2018.
As of March 31, 2019, we had the following Interest Rate Derivatives outstanding:

The following table shows the changes in the fair value and settlements of our Interest Rate Derivatives recorded in derivative gain (loss), net on our Consolidated Statements of Operations during the three months ended March 31, 2019 and 2018 (in millions):
Commodity Derivatives
SPL and CCL have entered into primarily indexbased physical natural gas supply contracts and associated economic hedges to purchase natural gas for the commissioning and operation of the SPL Project and the CCL Project. The terms of the physical natural gas supply contracts range up to eight years, some of which commence upon the satisfaction of certain conditions precedent.
We have entered into, and may from time to time enter into, financial LNG Trading Derivatives in the form of swaps, forwards, options or futures to economically hedge exposure to the commodity markets in which we have contractual arrangements to purchase or sell physical LNG. We have entered into LNG Trading Derivatives to secure a fixed price position to minimize future cash flow variability associated with LNG purchase and sale transactions.
The following table shows the fair value and location of our Liquefaction Supply Derivatives and LNG Trading Derivatives (collectively, “Commodity Derivatives”) on our Consolidated Balance Sheets (in millions, except notional amount):

FX Derivatives
The following table shows the fair value and location of our FX Derivatives on our Consolidated Balance Sheets (in millions):
The total notional amount of our FX Derivatives was $377 million and $379 million as of March 31, 2019 and December 31, 2018, respectively.
