	1. Organization and Nature of Operations

	As used in this report, the terms “PetroLogistics LP,” “the Partnership,” “we,” “our,” “us” or like terms, refer to PetroLogistics LP. References to PL Propylene refer to PL Propylene LLC, our sole operating subsidiary. References in this report to our “Sponsors” refer to Lindsay Goldberg LLC (“Lindsay Goldberg”) and York Capital Management who collectively and indirectly own 84% of PetroLogistics GP (our “General Partner”) and directly and indirectly own 63% of our common units.

	Organization

	PetroLogistics LP is a Delaware limited partnership that was formed on June 9, 2011, by Propylene Holdings LLC (“Propylene Holdings”) to own PL Propylene, a wholly-owned subsidiary of Propylene Holdings. The General Partner holds a non-economic interest in the Partnership.

	On March 30, 2012, Propylene Holdings contributed PL Propylene to PetroLogistics LP. Because this transaction was a transaction between entities under common control, the contributed assets and liabilities of PL Propylene were recorded in the consolidated financial statements at PL Propylene’s historical cost. Prior to the contribution, PetroLogistics LP had no operations and nominal assets and liabilities.

	Nature of Operations

	We currently own and operate the only U.S. propane dehydrogenation facility (the “facility”) producing polymer grade and chemical grade propylene from propane. Propylene is used as one of the basic building blocks for petrochemicals in a variety of end uses, including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. In addition to propylene, the facility generates commercial quantities of the following by-products during the production process: hydrogen, C4 mix stream, and C5+ stream.

	2. Summary of Significant Accounting Policies

	Basis of Presentation and Principles of Consolidation

	The interim consolidated financial statements and notes thereto have been prepared by management without audit according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been omitted pursuant to the SEC’s rules and regulations. However, management believes that the disclosures presented herein are adequate to fairly present the information. All inter-company transactions and balances have been eliminated upon consolidation. The accompanying interim consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report on Form 10-K as filed with the SEC on March 7, 2014.

	Use of Estimates

	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting periods. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ materially from those estimates. The results of operations of the Partnership for any interim period are not necessarily indicative of results for the full year.

	Derivative Instruments

	Commencing October 2011 and through March 2012, we entered into commodity derivative contracts (the “propane swaps”) with settlement dates in 2012 and 2013 to manage our exposure to commodity price risk with respect to propane, our sole feedstock. The propane swaps were designed to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our propane swaps were intended to act as a hedging (offset) mechanism against the volatility of energy commodity prices by allowing us to transfer some of the price risk to counterparties who were able and willing to bear it.

	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC” or “Codification”) Topic 815, Derivatives and Hedging (“ASC Topic 815”), addresses the accounting for derivative contracts. We entered into our commodity derivative contracts to economically hedge an exposure through a relationship that did not qualify for hedge accounting under ASC Topic 815. Our derivative contracts were recorded as derivative assets and liabilities, as applicable, at fair value on the consolidated balance sheets, and the associated unrealized gains and losses were recorded as current expense or income in the consolidated statements of comprehensive income. Unrealized gains or losses on commodity derivative contracts represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows in the consolidated statements of cash flows. Until settlement occurred, the changes in fair value of the propane swaps resulted in non-cash gains or losses being reported in our operating results as gain or loss on derivatives.

	Omnibus Agreement

	On May 9, 2012, the General Partner, the Partnership, Propylene Holdings, PL Propylene and PL Manufacturing LLC (“PL Manufacturing”) entered into an omnibus agreement (the “omnibus agreement”). Pursuant to the omnibus agreement and a related pledge agreement (the “pledge agreement”), we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the owners of 100% of the issued and outstanding equity interests in PL Manufacturing (the “PL Manufacturing Members”).

	On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

	While we did not bear any of the costs nor receive any of the benefits of the propane swaps, we remained a party to the propane swaps and were obligated to make payments to the propane swap counterparties as they came due and to post any collateral as required under the terms of the propane swap agreement. As a result, we continued to record the fair value of the propane swaps on our consolidated balance sheets with the related gains or losses reflected in our consolidated statements of comprehensive income. To the extent that we made payments under the propane swaps, PL Manufacturing and the PL Manufacturing Members were responsible for making quarterly capital contributions in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. During the three months ended March 31, 2013, we recorded a capital contribution of approximately $22.1 million for the reimbursement of the realized losses on the propane swaps that we incurred in the first quarter of 2013.

	In connection with the termination of the propane swaps, we paid a cancellation payment of $34.4 million in May 2013, of which $5.4 million was reimbursed to us through a reduction in the distribution paid to PL Manufacturing and the PL Manufacturing Members in May 2013 in accordance with the terms of the omnibus agreement. The remaining $29.0 million was settled with cash held as collateral by the propane swap counterparty, and we were immediately reimbursed by PL Manufacturing and the PL Manufacturing Members. We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms.

	Equity-Based Compensation

	We recognize compensation expense related to unit-based awards granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Note 6). The grant date fair value of the unit-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.

	Fair Value of Financial Instruments

	We consider cash and cash equivalents, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable-related parties, and accrued liabilities to be financial instruments in which the carrying amounts represent fair value because of the short-term nature of the accounts.

	Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated or generally unobservable inputs. We make certain assumptions we believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Partnership and its counterparties is incorporated in the valuation of assets and liabilities. We believe we use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

	The following table presents the financial instruments that require fair value disclosure as of March 31, 2014:

		Fair Value
		(in thousands)
		Level 1			Level 2			Level 3			Carrying Value
	Financial liabilities
	Senior notes		$	—		$	373,557		$	—		$	365,000

	The following table presents the financial instruments that require fair value disclosure as of December 31, 2013:

		Fair Value
		(in thousands)
		Level 1			Level 2			Level 3			Carrying Value
	Financial liabilities
	Senior notes		$	—		$	367,401		$	—		$	365,000

	The senior notes are deemed to be Level 2 financial instruments because the fair value is based on observable market data. At March 31, 2014 and December 31, 2013, the fair value of the senior notes was determined based on active trades and market corroborated data.

	There are no financial instruments that are split across the levels, and there have been no financial instruments that transferred between the levels during the three months ended March 31, 2014.

	Segment Reporting

	We operate in one segment for the production and sale of propylene and related by-products. All of our operations are located in Houston, Texas.

	Net Income Per Common Unit

	Net income per common unit for a given period is based on the distributions that are made to the unitholders plus an allocation of undistributed net income based on provisions of the partnership agreement, divided by the weighted average number of common units outstanding. The two-class method dictates that net income for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income as if all of the net income for the period had been distributed in accordance with the partnership agreement. Unit-based awards granted under the PetroLogistics Long-Term Incentive Plan (the “Long-Term Incentive Plan”) are eligible for Distribution Equivalent Rights (“DERs”). To the extent that non-forfeitable DERs are awarded, the underlying nonvested unit-based awards are considered participating securities for purposes of determining net income per unit. Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and unit-based awards outstanding. Undistributed losses (including those resulting from distributions in excess of net income) are allocated to common units based on provisions of the partnership agreement. Undistributed losses are not allocated to nonvested unit-based awards as they do not participate in net losses. Distributions declared and paid in the period are treated as distributed earnings in the computation of earnings per common unit even though cash distributions are not necessarily derived from current or prior period earnings.

The General Partner does not have an economic interest in the Partnership and, therefore, does not participate in the Partnership’s net income.

The following table provides a reconciliation of net income and the allocation of net income to the common units and the unit-based awards for purposes of computing net income per unit for the three months ended March 31, 2014 (in thousands, except units and per unit data):

	4. Derivative Instruments

	Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011 and through March 2012, we entered into derivative transactions with the intent of reducing volatility in our cash flows due to fluctuations in the price of propane, our sole feedstock. Under the terms of the arrangement, for a portion of our propane consumption, we locked in the price of propane as a fixed percentage of the price of Brent crude oil (the “contractual percentage”). Beginning in January 2012, and at the conclusion of each month thereafter through the May 2013 cancellation date, we performed a calculation to determine the average actual price of propane for that month as a percentage of the average actual price of Brent crude oil for that month (the “actual percentage”). If the actual percentage exceeded the contractual percentage under the propane swaps, we were owed a sum by the propane swaps counterparty. If the contractual percentage exceeded the actual percentage under the propane swaps, we owed a sum to the propane swaps counterparty.

	On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members. See Note 2 regarding the omnibus agreement.

	As of March 31, 2014 and December 31, 2013, we do not have any outstanding commodity forward contracts to hedge our forecasted energy commodity purchases.

	2012 Credit Facilities

	On March 27, 2012, PL Propylene, entered into a term loan facility of $350.0 million and a revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc., and the lenders party thereto (together, the “2012 credit facilities”). Borrowings under the 2012 credit facilities carried interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the term loan facility and the revolving credit facility ranged from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. During the first quarter of 2013, the interest rate on the term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

	The revolving credit facility also included a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the revolving credit facility. In addition, we paid an annual management fee for the term loan facility and the revolving credit facility. We were also required to pay a participation fee equal to the applicable margin for LIBOR loans, and a fronting fee to lenders participating in any letter of credit of 5.75%, and 0.125%, respectively.

	As required by our term loan facility, we entered into an interest rate protection agreement in July 2012 whereby we capped the three month LIBOR rate at 2.0% for up to $115.5 million on our term loan. The agreement terminated on March 27, 2014.

	2013 Credit Facilities and Debt Refinancing

	On March 28, 2013, we and our wholly-owned finance subsidiary, PetroLogistics Finance Corp., co-issued jointly and severally $365.0 million of senior unsecured notes due 2020 (the “senior notes”), and we amended and extended our revolving credit facility (together with the senior notes, the “2013 credit facilities”) from $120 million to $170 million with Morgan Stanley Senior Funding, Inc. (the “Agent”), and the lender parties thereto. We used the net proceeds from the issuance of the senior notes, after underwriting fees of $7.3 million, to (1) repay all borrowings outstanding under our term loan facility in the amount of $347.4 million, (2) pay $6.9 million for the call premium and costs associated with the cancellation of our term loan facility and (3) pay $3.0 million in commitment fees on our revolver and approximately $0.4 million in transaction fees. The proceeds from the senior notes, the repayment of the term loan and the transaction fees were net settled with the Agent as presented in the consolidated statement of cash flows for the quarter ended March 31, 2013. In addition, we incurred approximately $1.3 million in third party transaction costs. The senior notes were issued at the par value of $365 million and are reported as long-term debt in our consolidated balance sheets at March 31, 2014 and December 31, 2013.We recorded total deferred financing costs of approximately $12.0 million in connection with the issuance of the senior notes and the amendment and extension of our revolving credit facility. Cash paid for deferred financing costs totaled approximately $1.3 million with the remaining portion of $10.7 million net settled with the Agent through the senior note proceeds. We amortize the deferred financing costs using the effective interest method over the terms of the underlying credit facilities.

	The 2013 credit facilities contain certain restrictive financial covenants, including limitations on our ability to incur additional debt and the requirement under the terms of our revolver to maintain a total senior secured leverage ratio, as defined, no greater than 2.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2013, the aggregate amounts outstanding under the revolving credit facility exceeds $120 million.

	Interest Rate and Fees.

	The senior notes bear interest at a fixed rate of 6.25% per annum, payable on April 1 and October 1. The revolving credit facility bears interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the revolving credit facility ranges from 2.0% for loans bearing interest at the alternate base rate to 3.0% for loans bearing interest at LIBOR. The alternate base rate is defined as the greatest of the prime rate in effect and the federal funds effective rate in effect plus ½ of 1.0%. The revolving credit facility also contains a facility commitment fee at a rate of 0.50% per annum based on the daily unused amount of the commitment amount of $170 million payable in arrears on the last day of March, June, September and December of each year.

	Amortization and Final Maturity

	The senior notes have a maturity date of April 1, 2020. Prior to April 1, 2016, we may redeem all or part of the senior notes at a redemption price equal to the sum of 100% of the principal amount of the senior notes, plus a “make-whole” premium, plus accrued and unpaid interest, if any, to the date of redemption. We may also redeem some or all of the senior notes on or after April 1, 2016, at the redemption prices (expressed as percentages of principal) set forth below, plus accrued and unpaid interest, if any, on the notes redeemed to the applicable redemption date.

	Year	Percentage
	2016		103.125	%
	2017		101.563	%
	2018 and thereafter		100	%

	The revolving credit facility has a maturity date of March 28, 2018. At March 31, 2014, and December 31, 2013, there were no amounts outstanding under the revolving credit facility.

	Guarantees

	The senior notes rank equally in right of payment with all of our existing and future senior indebtedness. The notes are guaranteed on a senior unsecured basis by our wholly-owned subsidiary PL Propylene. The full and unconditional guarantee ranks equally with all of the existing and future senior indebtedness of our guarantor subsidiaries. PL Propylene and PetroLogistics Finance Corp. are our only subsidiaries. Finance Corp. has no material assets and does not conduct any operations. The Partnership has no independent assets or operations, and there are no significant restrictions upon our ability to obtain funds from our subsidiaries by dividend or loan. None of the assets of our subsidiaries represent restricted net assets pursuant to Rule 4-08(e)(3) of Regulation S-X under the Securities Act of 1933, as amended. The senior notes and the guarantee are effectively subordinated to all of our and our guarantor subsidiaries’ existing and future secured indebtedness to the extent of the value of the assets securing such indebtedness. In addition, the senior notes are structurally subordinated to all future indebtedness and other liabilities of any of our subsidiaries that are not issuers or guarantors of the senior notes.

	Loss on Extinguishment of Debt

	When we entered into the 2013 credit facilities, we recognized a loss on extinguishment of debt of approximately $20.4 million in our consolidated statements of comprehensive income for the three month period ended March 31, 2013. This loss on extinguishment resulted from the write off of approximately $7.7 million of unamortized deferred financing costs associated with the prior credit facilities. We also wrote off the unamortized original issue discount associated with the 2012 credit facilities in the amount of approximately $5.8 million. In addition, we paid a call premium of approximately $6.9 million for the prepayment of the term loan.

	6. Long-Term Incentive Plan

	2012 Long-Term Incentive Plan

	Our General Partner adopted The Long-Term Incentive Plan in May 2012. The Long-Term Incentive Plan is intended to promote our interests by providing incentive compensation, based on our common units, to employees, consultants and directors and to encourage superior performance. The Long-Term Incentive Plan provides for grants of restricted units, phantom units, unit awards and other unit-based awards up to a plan maximum of 5,882,352 common units.

	Unit-based Awards

	A unit-based award under the Long-Term Incentive Plan is a phantom unit whose terms and conditions are set by the Long-Term Incentive Plan administrative committee and that generally vests over a period of time and during that time is subject to forfeiture. Our unit-based awards to employees will generally vest over a three-year period either annually from the date of grant or upon the third anniversary of the grant date, provided the recipient has continuously provided services to us, our General Partner, or any other of our affiliates. Unit awards to members of our General Partner’s board of directors vest upon the first anniversary of the date of grant.

	Certain unit-based awards are eligible for DERs. Absent any restrictions on the DERs in an award agreement, we will pay DERs to the holder of the award without restriction at approximately the same time as we pay quarterly cash distributions to our common unitholders.

	During the three months ended March 31, 2014, we recognized total equity-based compensation expense of approximately $1.3 million related to the unit-based awards ($0.6 million as cost of sales and $0.7 million as general and administrative expense).

	During the three months ended March 31, 2013, we recognized total equity-based compensation expense of approximately $1.1 million related to the unit-based awards ($0.5 million as cost of sales and $0.6 million as general and administrative expense).

	The following table presents activity related to our Long-Term Incentive Plan awards, including those granted to employees during the three months ended March 31, 2014:

					Weighted average
		Unit-Based Awards			grant date fair value

	Awards granted		212,372			12
	Awards forfeited		—		$	—
	Awards outstanding March 31, 2014		756,146		$	14.26

	At March 31, 2014, none of the unit-based awards were vested. The aggregate intrinsic value of outstanding unit-based awards at March 31, 2014, was approximately $9.4 million. Also at March 31, 2014, total compensation cost related to nonvested employee unit-based awards that had not yet been recognized totaled approximately $7.5 million. The weighted-average period over which this amount will be recognized is approximately 2.2 years.

	At March 31, 2014, there were 23,289 non-vested phantom unit awards outstanding that were granted to our General Partner’s independent board members. Generally, these awards vest ratably over one year. No awards were granted to board members during the three months ended March 31, 2014. The aggregate intrinsic value of outstanding director unit-based awards at March 31, 2014, was approximately $0.3 million.

	Services Agreement with PetroLogistics GP LLC

	Our General Partner provides certain operational, managerial and general administrative services to us. All employees of PL Propylene and PetroLogistics LLC are employees of our General Partner. We reimburse the General Partner for all direct and indirect expenses the General Partner incurs or payments the General Partner makes on our behalf including, without limitation, salary, bonus, incentive cash compensation and employee benefits. During the three months ended March 31, 2014 and 2013, we incurred fees of $8.4 million and $7.1 million, respectively, under the services agreement with our General Partner. The amounts we pay the General Partner for these services are reported in the consolidated statements of comprehensive income in the line item to which the expense relates.

	During the three months ended March 31, 2014 and 2013, we utilized the services of a company owned by Lindsay Goldberg in the amounts of approximately $0.6 million and $0.4 million, respectively, in connection with facility maintenance activities which is reported in costs of sales.

Concentration of Risk	'
	8. Concentration of Risk

	Credit Risk Due to Industry and Customer Concentrations

	All of our revenues are derived from companies in the petrochemical industry, and our principal market is the Texas Gulf Coast region. This concentration could affect our overall exposure to credit risk since these customers may be affected by similar economic or other conditions. Generally, we do not require collateral for our accounts receivable; however, we attempt to negotiate prepayment agreements with customers that are deemed to be credit risks in order to minimize our potential exposure to any defaults.

	The following table presents the concentration of total sales to our largest customers:

		Three Months
		Ended
		March 31,
		2014			2013
	The Dow Chemical Company (“Dow”)		43	%		42	%
	Total Petrochemicals & Refining USA, Inc. (“Total”)		24	%		21	%
	INEOS Olefins and Polymers USA (“INEOS”)		21	%		21	%
	Others (less than 10% individually)		12	%		16	%
	Total sales		100	%		100	%

	We have entered into market-based sales contracts with our propylene customers to provide minimum and maximum annual quantities. (See Note 9). These maximum quantities comprise the substantial majority of our facility’s anticipated annual production of propylene. This concentration in the volume of business transacted with a limited number of customers subjects us to substantial risks. The loss of any of the above-named customers without replacement on comparable terms could adversely affect our business, results of operations and financial condition. If we were to lose one or more of our current customers, we would seek to engage in sales transactions with other petrochemical companies on either a long-term contract basis or in the spot market, although there is no assurance we would be able to do so.

	Feedstock Supplier Concentration Risk

	We have entered into long-term market-based contracts for the purchase of propane, our sole feedstock, as well as nitrogen and natural gas. There is only one supplier in each of these contracts. Interruptions in or limitations on volumes provided under these contracts subject us to the risk that we would be unable to meet our production requirements if we were unable to locate and procure replacement volumes from alternate sources.

	Legal Matters

	We are routinely involved in various legal matters arising from the normal course of business for which no provision has been made in the financial statements. While the outcome of these proceedings cannot be predicted with certainty, we believe that these proceedings, when resolved, will not have a material adverse effect on our results of operations financial position or liquidity.

	In March 2014, we received notice of a lawsuit filed against us for liability involving personal injuries sustained in February 2014 by a contractor’s employee working at our facility. Our third-party contracts contain indemnification clauses for incidents of this nature, including an obligation of the contractor to indemnify and defend us with respect to the applicable lawsuit. We also carry general liability insurance, subject to a deductible. We do not expect the cost of a settlement or eventual judgment, if any, to be material to our financial position or results of operations.

	Basis of Presentation and Principles of Consolidation

	The interim consolidated financial statements and notes thereto have been prepared by management without audit according to the rules and regulations of the Securities and Exchange Commission (“SEC”) and reflect all adjustments that, in the opinion of management, are necessary for a fair presentation of results for the periods presented. Such adjustments are of a normal recurring nature, unless otherwise disclosed. Certain information and notes normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) have been omitted pursuant to the SEC’s rules and regulations. However, management believes that the disclosures presented herein are adequate to fairly present the information. All inter-company transactions and balances have been eliminated upon consolidation. The accompanying interim consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our annual report on Form 10-K as filed with the SEC on March 7, 2014.
Use of Estimates	'
	Use of Estimates

	The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of sales and expenses during the reporting periods. We review our estimates on an ongoing basis using currently available information. Changes in facts and circumstances may result in revised estimates, and actual results could differ materially from those estimates. The results of operations of the Partnership for any interim period are not necessarily indicative of results for the full year.

Derivative Instruments	'
	Derivative Instruments

	Commencing October 2011 and through March 2012, we entered into commodity derivative contracts (the “propane swaps”) with settlement dates in 2012 and 2013 to manage our exposure to commodity price risk with respect to propane, our sole feedstock. The propane swaps were designed to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our propane swaps were intended to act as a hedging (offset) mechanism against the volatility of energy commodity prices by allowing us to transfer some of the price risk to counterparties who were able and willing to bear it.

	Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC” or “Codification”) Topic 815, Derivatives and Hedging (“ASC Topic 815”), addresses the accounting for derivative contracts. We entered into our commodity derivative contracts to economically hedge an exposure through a relationship that did not qualify for hedge accounting under ASC Topic 815. Our derivative contracts were recorded as derivative assets and liabilities, as applicable, at fair value on the consolidated balance sheets, and the associated unrealized gains and losses were recorded as current expense or income in the consolidated statements of comprehensive income. Unrealized gains or losses on commodity derivative contracts represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows in the consolidated statements of cash flows. Until settlement occurred, the changes in fair value of the propane swaps resulted in non-cash gains or losses being reported in our operating results as gain or loss on derivatives.
Omnibus Agreement	'
	Omnibus Agreement

	On May 9, 2012, the General Partner, the Partnership, Propylene Holdings, PL Propylene and PL Manufacturing LLC (“PL Manufacturing”) entered into an omnibus agreement (the “omnibus agreement”). Pursuant to the omnibus agreement and a related pledge agreement (the “pledge agreement”), we allocated all of our benefits and obligations under the propane swaps to PL Manufacturing and the owners of 100% of the issued and outstanding equity interests in PL Manufacturing (the “PL Manufacturing Members”).

	On April 19, 2013, we, PL Manufacturing and the counterparty to the propane swaps agreed to terminate the propane swaps remaining as of May 1, 2013. Under the omnibus agreement and the pledge agreement, any amounts that we were required to pay under the propane swaps were contributed to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

	While we did not bear any of the costs nor receive any of the benefits of the propane swaps, we remained a party to the propane swaps and were obligated to make payments to the propane swap counterparties as they came due and to post any collateral as required under the terms of the propane swap agreement. As a result, we continued to record the fair value of the propane swaps on our consolidated balance sheets with the related gains or losses reflected in our consolidated statements of comprehensive income. To the extent that we made payments under the propane swaps, PL Manufacturing and the PL Manufacturing Members were responsible for making quarterly capital contributions in an amount equal to the sum of all payments we made under such propane swaps during the applicable fiscal quarter or that we owed at the end of the quarter. During the three months ended March 31, 2013, we recorded a capital contribution of approximately $22.1 million for the reimbursement of the realized losses on the propane swaps that we incurred in the first quarter of 2013.

	In connection with the termination of the propane swaps, we paid a cancellation payment of $34.4 million in May 2013, of which $5.4 million was reimbursed to us through a reduction in the distribution paid to PL Manufacturing and the PL Manufacturing Members in May 2013 in accordance with the terms of the omnibus agreement. The remaining $29.0 million was settled with cash held as collateral by the propane swap counterparty, and we were immediately reimbursed by PL Manufacturing and the PL Manufacturing Members. We received the final reimbursement for realized losses from PL Manufacturing and the PL Manufacturing Members on August 14, 2013, at which time the omnibus agreement terminated in accordance with its terms.
Equity-Based Compensation	'
	Equity-Based Compensation

	We recognize compensation expense related to unit-based awards granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures (see Note 6). The grant date fair value of the unit-based awards is generally recognized on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards.

Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments

	We consider cash and cash equivalents, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable-related parties, and accrued liabilities to be financial instruments in which the carrying amounts represent fair value because of the short-term nature of the accounts.

	Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date in a principal or most advantageous market. Fair value is a market-based measurement that is determined based on inputs, which refer broadly to assumptions that market participants use in pricing assets or liabilities. These inputs can be readily observable, market corroborated or generally unobservable inputs. We make certain assumptions we believe that market participants would use in pricing assets or liabilities, including assumptions about risk, and the risks inherent in the inputs to valuation techniques. Credit risk of the Partnership and its counterparties is incorporated in the valuation of assets and liabilities. We believe we use valuation techniques that maximize the use of observable market-based inputs and minimize the use of unobservable inputs.

	The following table presents the financial instruments that require fair value disclosure as of March 31, 2014:

		Fair Value
		(in thousands)
		Level 1			Level 2			Level 3			Carrying Value
	Financial liabilities
	Senior notes		$	—		$	373,557		$	—		$	365,000

	Financial liabilities
	Senior notes		$	—		$	367,401		$	—		$	365,000

	The senior notes are deemed to be Level 2 financial instruments because the fair value is based on observable market data. At March 31, 2014 and December 31, 2013, the fair value of the senior notes was determined based on active trades and market corroborated data.

	There are no financial instruments that are split across the levels, and there have been no financial instruments that transferred between the levels during the three months ended March 31, 2014.

Net Income Per Common Unit	'
	Net Income Per Common Unit

	Net income per common unit for a given period is based on the distributions that are made to the unitholders plus an allocation of undistributed net income based on provisions of the partnership agreement, divided by the weighted average number of common units outstanding. The two-class method dictates that net income for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income as if all of the net income for the period had been distributed in accordance with the partnership agreement. Unit-based awards granted under the PetroLogistics Long-Term Incentive Plan (the “Long-Term Incentive Plan”) are eligible for Distribution Equivalent Rights (“DERs”). To the extent that non-forfeitable DERs are awarded, the underlying nonvested unit-based awards are considered participating securities for purposes of determining net income per unit. Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and unit-based awards outstanding. Undistributed losses (including those resulting from distributions in excess of net income) are allocated to common units based on provisions of the partnership agreement. Undistributed losses are not allocated to nonvested unit-based awards as they do not participate in net losses. Distributions declared and paid in the period are treated as distributed earnings in the computation of earnings per common unit even though cash distributions are not necessarily derived from current or prior period earnings.

	The General Partner does not have an economic interest in the Partnership and, therefore, does not participate in the Partnership’s net income.

	The following table provides a reconciliation of net income and the allocation of net income to the common units and the unit-based awards for purposes of computing net income per unit for the three months ended March 31, 2014 (in thousands, except units and per unit data):
