Basis of Presentation	'
	BASIS OF PRESENTATION
	The accompanying unaudited Financial Statements of Sabine Pass Liquefaction, LLC have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation, have been included. Certain reclassifications have been made to conform prior period information to the current presentation.  The reclassifications had no effect on our overall financial position, results of operations or cash flows. Results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2014.
	We are a development stage company formed on June 24, 2010 by Cheniere Energy Partners, L.P. ("Cheniere Partners") to own, develop and operate natural gas liquefaction facilities in Cameron Parish, Louisiana (the "Liquefaction Project") at the Sabine Pass liquefied natural gas ("LNG") terminal (the "Sabine Pass LNG terminal") adjacent to the existing regasification facilities owned and operated by Sabine Pass LNG, L.P. ("Sabine Pass LNG"). Cheniere Partners is a publicly traded limited partnership (NYSE MKT: CQP) that is an indirect 49.2% owned subsidiary of Cheniere Energy, Inc. ("Cheniere"), a Houston-based energy company primarily engaged in LNG-related businesses (NYSE MKT: LNG). We and Sabine Pass LNG are each indirect wholly owned subsidiaries of Cheniere Energy Investments, LLC ("Cheniere Investments"), which is a wholly owned subsidiary of Cheniere Partners.
	We plan to construct up to six Trains, which are in various stages of development. Each Train is expected to have nominal production capacity of approximately 4.5 mtpa of LNG. Operations to date have been devoted to pre-construction and construction activities of the Liquefaction Project. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Our ultimate profitability will depend on, among other factors, obtaining financing, and completion of construction and commencement of commercial operations of the Liquefaction Project. As of March 31, 2014, we had a cumulative net loss of $385.9 million. In addition, Cheniere Partners has committed to provide financing necessary to financially support us. No owner of Sabine Pass Liquefaction is liable for Sabine Pass Liquefaction's debts, liabilities or obligations beyond such owner's capital contribution.
	Because we are a development stage enterprise, we have presented our financial statements in accordance with guidance applicable to development stage entities. Our Statements of Operations also include expense allocations for certain corporate functions historically performed by Cheniere, including allocations of material general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification of time and/or activities associated with Sabine Pass Liquefaction, employee headcount or capital expenditures. Our management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from Cheniere, are reasonable. Nevertheless, the financial statements may not include all of the actual expenses that would have been incurred had we been a stand-alone company during the periods presented and may not reflect our results of operations, financial position and cash flows had we been a stand-alone company during the periods presented. Actual costs that would have been incurred if we had been a stand-alone company would depend on multiple factors, including the organization's structure and strategic decisions made in various areas, including information technology and infrastructure.
	We are a disregarded entity for federal and state income tax purposes. Our taxable income or loss, which may vary substantially from the net income or loss reported on our Statements of Operations, is able to be included in the federal income tax return of Cheniere Partners. Accordingly, no provision or liability for federal or state income taxes is included in the accompanying Financial Statements.
	For further information, refer to the financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2013.

Restricted Cash and Cash Equivalents	'
	RESTRICTED CASH AND CASH EQUIVALENTS
	Restricted cash and cash equivalents consist of funds that are contractually restricted as to usage or withdrawal and have been presented separately from cash and cash equivalents on our Balance Sheets.
	In July 2012, we entered into a construction/term loan facility in an amount up to $3.6 billion (the "2012 Liquefaction Credit Facility"). During 2013, we issued an aggregate principal amount of $2.0 billion, before premium, of 5.625% Senior Secured Notes due 2021 (the "2021 Senior Notes"), $1.0 billion of 6.25% Senior Secured Notes due 2022 (the "2022 Senior Notes") and $1.0 billion of 5.625% Senior Secured Notes due 2023 (the "2023 Senior Notes" and collectively with the 2021 Senior Notes and the 2022 Senior Notes, the "Senior Notes"). Also during 2013, we entered into four credit facilities aggregating $5.9 billion (collectively, the "2013 Liquefaction Credit Facilities"), which amended and restated the 2012 Liquefaction Credit Facility. See Note 5—"Long-Term Debt". Under the terms and conditions of the 2012 Liquefaction Credit Facility and the 2013 Liquefaction Credit Facilities, we are required to deposit all cash received into reserve accounts controlled by a collateral trustee. Therefore, all of our cash and cash equivalents are shown as restricted cash and cash equivalents on our Balance Sheets. As of March 31, 2014 and December 31, 2013, we classified $96.9 million and $192.1 million, respectively, as current restricted cash and cash equivalents for the payment of current liabilities related to the Liquefaction Project and $197.5 million and $867.6 million, respectively, as non-current restricted cash and cash equivalents for future Liquefaction Project construction costs.

	Total long-term debt, net of premium	$	4,111,222	$	4,111,562
	Senior Notes
	In February 2013 and April 2013, we issued an aggregate principal amount of $2.0 billion, before premium, of the 2021 Senior Notes. In April 2013, we also issued $1.0 billion of the 2023 Senior Notes. Borrowings under the 2021 Senior Notes and 2023 Senior Notes bear interest at a fixed rate of 5.625%. In November 2013, we issued an aggregate principal amount of $1.0 billion of the 2022 Senior Notes. Borrowings under the 2022 Senior Notes bear interest at a fixed rate of 6.25%. Interest on the Senior Notes is payable semi-annually in arrears.
	The terms of the Senior Notes are governed by a common indenture (the "Indenture"). The Indenture contains customary terms and events of default and certain covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to incur additional indebtedness or issue preferred stock, make certain investments or pay dividends or distributions on capital stock or subordinated indebtedness or purchase, redeem or retire capital stock, sell or transfer assets, including capital stock of our restricted subsidiaries, restrict dividends or other payments by restricted subsidiaries, incur liens, enter into transactions with affiliates, consolidate, merge, sell or lease all or substantially all of our assets and enter into certain LNG sales contracts. Subject to permitted liens, the Senior Notes are secured on a pari passu first-priority basis by a security interest in all of our membership interests and substantially all of our assets. We may not make any distributions until, among other requirements, substantial completion of Trains 1 and 2 has occurred, deposits are made into debt service reserve accounts and a debt service coverage ratio for the prior 12-month period and a projected debt service coverage ratio for the upcoming 12-month period of 1.25:1.00 are satisfied.
	At any time prior to November 1, 2020, with respect to the 2021 Senior Notes; December 15, 2021, with respect to the 2022 Senior Notes; or January 15, 2023, with respect to the 2023 Senior Notes, we may redeem all or part of the Senior Notes at a redemption price equal to the "make-whole" price set forth in the Indenture, plus accrued and unpaid interest, if any, to the date of redemption. We may also at any time on or after November 1, 2020, with respect to the 2021 Senior Notes; December 15, 2021, with respect to the 2022 Senior Notes; or January 15, 2023, with respect to the 2023 Senior Notes, redeem all or part of the Senior Notes at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest, if any, to the date of redemption.
	In connection with the issuance of the 2022 Senior Notes, we also entered into a registration rights agreement (the "2022 Liquefaction Registration Rights Agreement"). Under the 2022 Liquefaction Registration Rights Agreement, we have agreed to use commercially reasonable efforts to file with the Securities and Exchange Commission ("SEC") and cause to become effective a registration statement relating to an offer to exchange the 2022 Senior Notes for a like aggregate principal amount of SEC-registered notes with terms identical in all material respects to the 2022 Senior Notes (other than with respect to restrictions on transfer or to any increase in annual interest rate) within 360 days after November 25, 2013.  Under specified circumstances, we may be required to file a shelf registration statement to cover resales of the Senior Notes.  If we fail to satisfy this obligation, we may be required to pay additional interest to holders of the 2022 Senior Notes under certain circumstances.
	2013 Liquefaction Credit Facilities
	In May 2013, we entered into the 2013 Liquefaction Credit Facilities aggregating $5.9 billion. The 2013 Liquefaction Credit Facilities are being used to fund a portion of the costs of developing, constructing and placing into operation the first four Trains of the Liquefaction Project. The 2013 Liquefaction Credit Facilities will mature on the earlier of May 28, 2020 or the second anniversary of the completion date of the first four Trains of the Liquefaction Project, as defined in the 2013 Liquefaction Credit Facilities. Borrowings under the 2013 Liquefaction Credit Facilities may be refinanced, in whole or in part, at any time without premium or penalty, except for interest rate hedging and interest rate breakage costs. We made a $100.0 million borrowing under the 2013 Liquefaction Credit Facilities in June 2013 after meeting the required conditions precedent.
	We had $4.9 billion of available commitments under the 2013 Liquefaction Credit Facilities as of both March 31, 2014 and December 31, 2013 as a result of our initial $100.0 million borrowing and the termination of approximately $885 million of commitments in connection with the issuance of the 2022 Senior Notes in November 2013 as described below.
	Borrowings under the 2013 Liquefaction Credit Facilities bear interest at a variable rate per annum equal to, at our election, the London Interbank Offered Rate ("LIBOR") or the base rate, plus the applicable margin. The applicable margins for LIBOR loans range from 2.3% to 3.0% prior to the completion of Train 4 and from 2.3% to 3.25%, after such completion, depending on the applicable 2013 Liquefaction Credit Facility. Interest on LIBOR loans is due and payable at the end of each LIBOR period. The 2013 Liquefaction Credit Facilities required us to pay certain up-front fees to the agents and lenders in the aggregate amount of approximately $144 million and provide for a commitment fee calculated at a rate per annum equal to 40% of the applicable margin for LIBOR loans, multiplied by the average daily amount of the undrawn commitment due quarterly in arrears. Annual administrative fees must also be paid to the agent and the trustee. The principal of the loans made under the 2013 Liquefaction Credit Facilities must be repaid in quarterly installments, commencing with the earlier of the last day of the first full calendar quarter after the Train 4 completion date, as defined in the 2013 Liquefaction Credit Facilities, or September 30, 2018. Scheduled repayments are based upon an 18-year amortization profile, with the remaining balance due upon the maturity of the 2013 Liquefaction Credit Facilities.
	Under the terms and conditions of the 2013 Liquefaction Credit Facilities, all cash held by us is controlled by a collateral agent. These funds can only be released by the collateral agent upon satisfaction of certain terms and conditions related to the use of proceeds, and are classified as restricted on our Balance Sheets.
	The 2013 Liquefaction Credit Facilities contain conditions precedent for the second borrowing and any subsequent borrowings, as well as customary affirmative and negative covenants. Our obligations under the 2013 Liquefaction Credit Facilities are secured by substantially all of our assets as well as all of our membership interests on a pari passu basis with the Senior Notes.
	Under the terms of the 2013 Liquefaction Credit Facilities, we are required to hedge not less than 75% of the variable interest rate exposure of our projected outstanding borrowings, calculated on a weighted average basis in comparison to our anticipated draw of principal. See Note 6—"Financial Instruments".
	In November 2013, we issued the 2022 Senior Notes, and a portion of the available commitments pursuant to the 2013 Liquefaction Credit Facilities was terminated. Net proceeds from the offering of approximately $978 million are being used to pay a portion of the capital costs in connection with the construction of the first four Trains of the Liquefaction Project in lieu of the terminated portion of the commitments under the 2013 Liquefaction Credit Facilities. The 2022 Senior Notes are pari passu in right of payment with all of our existing and future senior debt. As a result of our issuance of the 2022 Notes in November 2013, we have terminated approximately $885 million of commitments under the 2013 Liquefaction Credit Facilities. This termination resulted in a write-off of debt issuance costs and deferred commitment fees associated with the 2013 Liquefaction Credit Facilities of $43.3 million in November 2013.
	2012 Liquefaction Credit Facility
	In July 2012, we entered into the 2012 Liquefaction Credit Facility with a syndicate of lenders. The 2012 Liquefaction Credit Facility was intended to be used to fund a portion of the costs of developing, constructing and placing into operation Trains 1 and 2 of the Liquefaction Project. Borrowings under the 2012 Liquefaction Credit Facility were based on LIBOR plus 3.50% during construction and LIBOR plus 3.75% during operations. We were also required to pay commitment fees on the undrawn amount. In May 2013, the 2012 Liquefaction Credit Facility was amended and restated with the 2013 Liquefaction Credit Facilities and $100.0 million of outstanding borrowings under the 2012 Liquefaction Credit Facility were repaid in full.
	Under the terms of the 2012 Liquefaction Credit Facility, we were required to hedge not less than 75% of the variable interest rate exposure of our projected outstanding borrowings, calculated on a weighted average basis in comparison to our anticipated draw of principal. See Note 6—"Financial Instruments".

	The following table (in thousands) shows the fair value of our LNG Inventory Derivatives and Interest Rate Derivatives that are required to be measured at fair value on a recurring basis as of March 31, 2014 and December 31, 2013, which are classified as prepaid expenses and other, non-current derivative assets and derivative liabilities in our Balance Sheets.

	The estimated fair values of our LNG Inventory Derivatives are the amounts at which the instruments could be exchanged currently between willing parties. We value these derivatives using observable commodity price curves and other relevant data. We value our Interest Rate Derivatives using valuations based on the initial trade prices. Using an income-based approach, subsequent valuations are based on observable inputs to the valuation model including interest rate curves, risk adjusted discount rates, credit spreads and other relevant data. 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.
	LNG Inventory Derivatives
	We recognize all derivative instruments that qualify for derivative accounting treatment as either assets or liabilities and measure those instruments at fair value. The changes in fair value are reported in earnings.
	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 where our LNG Inventory Derivatives are in an asset position. Our commodity derivative transactions are executed through over-the-counter contracts which are subject to nominal credit risk as these transactions are settled on a daily margin basis with investment grade financial institutions. We are required by these financial institutions to use margin deposits as credit support for our commodity derivative activities. Collateral of zero and $0.2 million deposited for such contracts, which has not been reflected in the derivative fair value tables, is included in the other current assets balance as of March 31, 2014 and December 31, 2013, respectively.
	The following table (in thousands) shows the fair value and location of our LNG Inventory Derivatives on our Balance Sheets:

	Interest Rate Derivatives
	In August 2012 and June 2013, we entered into Interest Rate Derivatives to protect against volatility of future cash flows and hedge a portion of the variable interest payments on the 2012 Liquefaction Credit Facility and the 2013 Liquefaction Credit Facilities, respectively. The Interest Rate Derivatives hedge a portion of the expected outstanding borrowings over the term of the 2013 Liquefaction Credit Facilities.
	We designated the Interest Rate Derivatives entered into in August 2012 as hedging instruments which was required in order to qualify for cash flow hedge accounting. As a result of this cash flow hedge designation, we recognized the Interest Rate Derivatives entered into in August 2012 as an asset or liability at fair value, and reflected changes in fair value through other comprehensive income in our Statements of Comprehensive Loss.
	Any hedge ineffectiveness associated with the Interest Rate Derivatives entered into in August 2012 was recorded immediately as derivative gain (loss) in our Statements of Operations.  The realized gain (loss) on the Interest Rate Derivatives entered into in August 2012 was recorded as an (increase) decrease in interest expense on our Statements of Operations to the extent not capitalized as part of the Liquefaction Project. The effective portion of the gains or losses on our Interest Rate Derivatives entered into in August 2012 recorded in other comprehensive income would have been reclassified to earnings as interest payments on the 2012 Liquefaction Credit Facility impact earnings. In addition, amounts recorded in other comprehensive income are also reclassified into earnings if it becomes probable that the hedged forecasted transaction will not occur.
	We did not elect to designate the Interest Rate Derivatives entered into in June 2013 as cash flow hedging instruments, and changes in fair value are recorded as derivative gain (loss) within our Statements of Operations.
	During the first quarter of 2013, we determined that it was no longer probable that the forecasted variable interest payments on the 2012 Liquefaction Credit Facility would occur in the time period originally specified based on the continued development of our financing strategy for the Liquefaction Project, and, in particular, the Senior Notes described in Note 5—"Long-Term Debt". As a result, all of the Interest Rate Derivatives entered into in August 2012 were no longer effective hedges, and the remaining portion of hedge relationships that were designated cash flow hedges as of December 31, 2012, were de-designated as of February 1, 2013. For de-designated cash flow hedges, changes in fair value prior to their de-designation date are recorded as other comprehensive income (loss) within our Balance Sheets, and changes in fair value subsequent to their de-designation date are recorded as derivative gain (loss) within our Statements of Operations.
	In June 2013, we concluded that the hedged forecasted transactions associated with the Interest Rate Derivatives entered into in connection with the 2012 Liquefaction Credit Facility had become probable of not occurring based on the issuances of the Senior Notes, the closing of the 2013 Liquefaction Credit Facilities, the additional Interest Rate Derivatives executed in June 2013, and our intention to continue to issue fixed rate debt to refinance the 2013 Liquefaction Credit Facilities. As a result, the amount remaining in accumulated other comprehensive income ("AOCI") pertaining to the previously designated Interest Rate Derivatives was reclassified out of AOCI and into income. We have presented the reclassification of unrealized losses from AOCI into income and the changes in fair value and settlements subsequent to the reclassification date separate from interest expense as derivative gain (loss), net in our Statements of Operations.
	At March 31, 2014, we had the following Interest Rate Derivatives outstanding:

	Services Agreements
	During the three months ended March 31, 2014 and 2013 and the period from June 24, 2010 (date of inception) through March 31, 2014, we recorded general and administrative expense—affiliate of 19.9 million, $13.5 million and $146.1 million, respectively, under the following service agreements:
	Sabine Pass Liquefaction O&M Agreement
	We have entered into an operation and maintenance agreement (the "Liquefaction O&M Agreement") with Cheniere Investments pursuant to which we receive all of the necessary services required to construct, operate and maintain the liquefaction facilities. Before the liquefaction facilities are operational, the services to be provided include, among other services, obtaining governmental approvals on our behalf, preparing an operating plan for certain periods, obtaining insurance, preparing staffing plans and preparing status reports. After the liquefaction facilities are operational, the services include all necessary services required to operate and maintain the liquefaction facilities. Before the liquefaction facilities are operational, in addition to reimbursement of operating expenses, we are required to pay a monthly fee equal to 0.6% of the capital expenditures incurred in the previous month. After substantial completion of each Train, for services performed while the liquefaction facilities are operational, we will pay in addition to the reimbursement of operating expenses, a fixed monthly fee of $83,333 (indexed for inflation) for services with respect to such Train. Cheniere Investments provides the services required under the Liquefaction O&M Agreement pursuant to a secondment agreement with a wholly owned subsidiary of Cheniere.
	Sabine Liquefaction MSA
	We have entered into a management services agreement (the "Liquefaction MSA") with a wholly owned subsidiary of Cheniere pursuant to which such subsidiary manages the construction and operation of the liquefaction facilities, excluding those matters provided for under the Liquefaction O&M Agreement. The services include, among other services, exercising the day-to-day management of our affairs and business, managing our regulatory matters, managing bank and brokerage accounts and financial books and records of our business and operations, entering into financial derivatives on our behalf and providing contract administration services for all contracts associated with the liquefaction facilities. We pay a monthly fee equal to 2.4% of the capital expenditures incurred in the previous month. After substantial completion of each Train, we will pay a fixed monthly fee of $541,667 for services with respect to such Train.
	Terminal Use Agreements
	We have entered into a terminal use agreement ("TUA") with Sabine Pass LNG to provide berthing for LNG vessels and for the unloading, loading, storage and regasification of LNG. We have reserved approximately 2.0 Bcf/d of regasification capacity and we are obligated to make monthly capacity payments to Sabine Pass LNG aggregating approximately $250.0 million per year, continuing until at least 20 years after we deliver our first commercial cargo at our facilities under construction. We obtained this reserved capacity as a result of an assignment in July 2012 by Cheniere Investments of its rights, title and interest under its TUA. In connection with the assignment, we, Cheniere Investments and Sabine Pass LNG also entered into a terminal use rights assignment and agreement ("TURA") pursuant to which Cheniere Investments has the right to use our reserved capacity under the TUA and has the obligation to make the monthly capacity payments required by the TUA to Sabine Pass LNG.  Cheniere Investments' right to use our capacity at the Sabine Pass LNG terminal will be reduced as each of Trains 1 through 4 reaches commercial operation. The percentage of the monthly capacity payments payable by Cheniere Investments will be reduced from 100% to zero (unless Cheniere Investments utilizes terminal use capacity after Train 4 reaches commercial operations), and the percentage of the monthly capacity payments payable by us will increase by the amount that Cheniere Investments' percentage decreases. Cheniere Partners has guaranteed our obligations under our TUA and the obligations of Cheniere Investments under the TURA.
	In connection with our TUA, we are required to pay for a portion of the cost to maintain the cryogenic readiness of the regasification facilities at the Sabine Pass LNG terminal. Terminal use agreement maintenance expense—affiliate represents the amount recorded related to the reimbursement to Sabine Pass LNG of a portion of its fuel costs related to maintaining the cryogenic readiness of the Sabine Pass LNG terminal. Our portion of the cost (including affiliate) to maintain the cryogenic readiness of the regasification facilities at the Sabine Pass LNG terminal is based on our approximately 41% share of the commercial LNG storage capacity at the Sabine Pass LNG terminal. During the three months ended March 31, 2014 and 2013, we recorded credits of $0.2 million and $0.3 million, respectively, and during the period from June 24, 2010 (date of inception) through March 31, 2014, we recorded $36.4 million as terminal use agreement maintenance expense (including affiliate) on our Statements of Operations related to this obligation.
	Cheniere Marketing Sale and Purchase Agreement ("SPA")
	Cheniere Marketing has entered into an SPA with us (the "Cheniere Marketing SPA") to purchase, at Cheniere Marketing's option, up to 104,000,000 MMBtu/yr of LNG. We have the right each year during the term of the SPA to reduce the annual contract quantity based on its assessment of how much LNG it can produce in excess of that required for other customers. Cheniere Marketing may purchase incremental LNG volumes at a price of 115% of Henry Hub plus up to $3.00 per MMBtu for the most profitable 36,000,000 MMBtu of cargoes sold each year by Cheniere Marketing, and then 20% of net profits of the remaining 68,000,000 MMBtu sold each year by Cheniere Marketing.
	LNG Site Sublease Agreement
	In June 2012, we entered into an agreement with Sabine Pass LNG to sublease a portion of its Sabine Pass LNG terminal site for the Liquefaction Project. The annual sublease payment is $0.5 million. The initial term of the sublease expires on December 31, 2034, with options to renew for five 10-year extensions with similar terms as the initial term. The annual sublease payment will be adjusted for inflation every five years based on a consumer price index, as defined in the sublease agreement. During the three months ended March 31, 2014 and 2013 and the period from June 24, 2010 (date of inception) through March 31, 2014, we recorded $0.1 million, $0.1 million, and $0.9 million, respectively, of sublease expense as general and administrative expense—affiliate on our Statements of Operations.

Basis of Presentation	'
	The accompanying unaudited Financial Statements of Sabine Pass Liquefaction, LLC have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation, have been included. Certain reclassifications have been made to conform prior period information to the current presentation.  The reclassifications had no effect on our overall financial position, results of operations or cash flows. Results of operations for the three months ended March 31, 2014 are not necessarily indicative of the results of operations that will be realized for the year ending December 31, 2014.
	We are a development stage company formed on June 24, 2010 by Cheniere Energy Partners, L.P. ("Cheniere Partners") to own, develop and operate natural gas liquefaction facilities in Cameron Parish, Louisiana (the "Liquefaction Project") at the Sabine Pass liquefied natural gas ("LNG") terminal (the "Sabine Pass LNG terminal") adjacent to the existing regasification facilities owned and operated by Sabine Pass LNG, L.P. ("Sabine Pass LNG"). Cheniere Partners is a publicly traded limited partnership (NYSE MKT: CQP) that is an indirect 49.2% owned subsidiary of Cheniere Energy, Inc. ("Cheniere"), a Houston-based energy company primarily engaged in LNG-related businesses (NYSE MKT: LNG). We and Sabine Pass LNG are each indirect wholly owned subsidiaries of Cheniere Energy Investments, LLC ("Cheniere Investments"), which is a wholly owned subsidiary of Cheniere Partners.
	We plan to construct up to six Trains, which are in various stages of development. Each Train is expected to have nominal production capacity of approximately 4.5 mtpa of LNG. Operations to date have been devoted to pre-construction and construction activities of the Liquefaction Project. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. Our ultimate profitability will depend on, among other factors, obtaining financing, and completion of construction and commencement of commercial operations of the Liquefaction Project. As of March 31, 2014, we had a cumulative net loss of $385.9 million. In addition, Cheniere Partners has committed to provide financing necessary to financially support us. No owner of Sabine Pass Liquefaction is liable for Sabine Pass Liquefaction's debts, liabilities or obligations beyond such owner's capital contribution.
	Because we are a development stage enterprise, we have presented our financial statements in accordance with guidance applicable to development stage entities. Our Statements of Operations also include expense allocations for certain corporate functions historically performed by Cheniere, including allocations of material general corporate expenses related to executive oversight, accounting, treasury, tax, legal, procurement and information technology. These allocations are based primarily on specific identification of time and/or activities associated with Sabine Pass Liquefaction, employee headcount or capital expenditures. Our management believes the assumptions underlying the financial statements, including the assumptions regarding allocating general corporate expenses from Cheniere, are reasonable. Nevertheless, the financial statements may not include all of the actual expenses that would have been incurred had we been a stand-alone company during the periods presented and may not reflect our results of operations, financial position and cash flows had we been a stand-alone company during the periods presented. Actual costs that would have been incurred if we had been a stand-alone company would depend on multiple factors, including the organization's structure and strategic decisions made in various areas, including information technology and infrastructure.
	We are a disregarded entity for federal and state income tax purposes. Our taxable income or loss, which may vary substantially from the net income or loss reported on our Statements of Operations, is able to be included in the federal income tax return of Cheniere Partners. Accordingly, no provision or liability for federal or state income taxes is included in the accompanying Financial Statements.
	For further information, refer to the financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2013.
