NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

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. The information presented in this Quarterly Report on Form 10-Q contains the unaudited combined financial results of PL Propylene LLC (PL Propylene), our predecessor for accounting purposes (the Predecessor), for all periods presented through March 30, 2012. The consolidated financial results for the three and nine months ended September 30, 2012, also include the results of operations of the Partnership for the period beginning March 30, 2012, the date of the contribution of the Predecessor’s net assets to the Partnership. The consolidated balance sheet as of September 30, 2012, presents solely the consolidated financial position of the Partnership. References in this report to our “Sponsors” refer to Lindsay Goldberg LLC (Lindsay Goldberg) and York Capital Management which, after completion of our initial public offering (the Offering), collectively and indirectly own 84% of PetroLogistics GP (our General Partner) and directly and indirectly own 63% of our common units. See Note 3 to these consolidated financial statements for information regarding the Offering.

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 own and operate the only U.S. propane dehydrogenation facility producing propylene from propane.  We developed and built new assets and converted certain existing assets into an “on-purpose” propylene production facility (the Facility) in Houston, Texas, following the purchase of a former olefins manufacturing facility from ExxonMobil Oil Corporation in March 2008. Production at the Facility began on October 21, 2010. 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. The propane dehydrogenation process also produces certain by-products, which we include as sales.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

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. The accompanying interim consolidated financial statements do not include all the notes that would be included in our annual financial statements and, therefore, should be read in conjunction with the financial statements and notes thereto included in our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.

Summary of Significant Accounting Policies

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 period. 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 or our Predecessor for any interim period are not necessarily indicative of results for the full year.

2. Basis of Presentation and Summary of Significant Accounting Policies (Continued)

Derivative Instruments

Commencing October 2011, 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. Our principal use of the Propane Swaps is to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our Propane Swaps 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 are able and willing to bear it.

In addition to the Propane Swaps, 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 new term loan. The agreement terminates March 27, 2014.

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 enter into our commodity derivative contracts to economically hedge an exposure through a relationship that does not qualify for hedge accounting under ASC Topic 815. Our derivative contracts are recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet, and the associated unrealized gains and losses are recorded as current expense or income in the statement of comprehensive income (loss). 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 on the cash flow statement. Until settlement occurs, this will result 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), the Partnership allocated all of its 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).

Under the Omnibus Agreement and the Pledge Agreement, any amounts received by the Partnership under the Propane Swaps will be distributed to PL Manufacturing and the PL Manufacturing Members, and any amounts that the Partnership is required to pay under the Propane Swaps will be contributed to the Partnership as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

While the Partnership does not receive any of the benefits of the Propane Swaps, it remains a party to the Propane Swaps, and will be obligated to make payments to the Propane Swap counterparties as they come due and to post any collateral as required, under the terms of the Propane Swap agreement. As a result, the Partnership will continue to record the fair value of the Propane Swaps on its balance sheet with the related charge being reflected in its statement of comprehensive income (loss) in accordance with SEC Staff Accounting Bulletin No. 79. To the extent that the Partnership makes payments under the Propane Swaps, PL Manufacturing and the PL Manufacturing Members will be responsible for making quarterly capital contributions in an amount equal to the sum of all payments made by the Partnership under such Propane Swaps during the applicable fiscal quarter or owed by the Partnership at the end of the quarter. During the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members contributed approximately $16 million to the Partnership as reimbursement for realized losses on the Propane Swaps pro-rated from May 9, 2012, the closing date of the Offering, through June 30, 2012. The contribution was made in the form of a reduction in the cash distribution paid to PL Manufacturing and the PL Manufacturing Members. For realized losses on the Propane Swaps in the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members will contribute approximately $31.0 million to the Partnership in November 2012 which is reflected as a related party account receivable at September 30, 2012, in our consolidated balance sheet. The contribution will be partially funded through a reduction in the cash distribution to PL Manufacturing and the PL Manufacturing Members in November 2012 with the remaining portion funded with a cash payment of approximately $9.2 million from PL Manufacturing and the PL Manufacturing Members. In April 2012, we deposited $40.0 million in cash with the Propane Swaps counterparty. The cash is held by the counterparty and is reported as prepaid and other current assets in our consolidated balance sheet.

The Partnership expects that PL Manufacturing and the PL Manufacturing Members will continue to fund their future payment obligations primarily through quarterly distributions that they receive on common units that they own and through the form of additional cash payments should the quarterly distribution not be adequate to cover the amount due on the realized losses from the Propane Swaps. Under the Pledge Agreement, the PL Manufacturing Members pledged to PL Manufacturing (as collateral agent) a number of common units such that, at all times, the market value of all pledged units and all common units owned by PL Manufacturing that are subject to the Omnibus Agreement is equal to or greater than 10 times the mark-to-market value of the Propane Swaps, but in no event shall the number of pledged units be greater than the amount of units distributed to PL Manufacturing and the PL Manufacturing Members in connection with the Offering. The expected aggregate quarterly distributions payable on all pledged common units, together with a cash reserve held by PL Manufacturing, are expected to be sufficient to cover future payments under the Propane Swaps.

Equity-Based Compensation

We recognize compensation expense related to equity-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 7). The grant date fair value of the equity-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.

We also account for equity-based awards granted to non-employees based on the estimated fair value of the awards. The measurement of equity-based compensation for awards granted to non-employees is subject to periodic adjustment as the awards vest, and the resulting change in value is recognized in the statement of comprehensive income (loss) during the period the related services are rendered.

Fair Value of Financial Instruments

We consider cash, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable, 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. The Partnership makes certain assumptions it believes 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. The Partnership believes it uses 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 September 30, 2012.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	2,401	$	—	$	2,401
Financial liabilities
Variable rate debt	$	—	$	345,843	$	—	$	341,925
Propane swaps	—		94,738		—		94,738

The following table presents the financial instruments that require fair value disclosure as of December 31, 2011.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	6,178	$	—	$	6,178
Financial liabilities
Variable rate debt	—		145,115		—		145,115
Propane swaps	—		7,845		—		7,845

The variable rate debt is deemed to be a Level 2 financial instrument because it is based on observable market data. At September 30, 2012, the fair value was determined based on active trades and market corroborated data. To determine the fair value at December 31, 2011, we reviewed the current market interest rates and terms of similar debt, and concluded that the carrying value of the variable rate debt approximates the fair value.

The valuation assumptions utilized to measure the fair value of our Propane Swaps were observable inputs based on market data obtained from independent sources and are considered Level 2 inputs. To determine the fair value of the Propane Swaps, we utilized quoted prices for similar assets, liabilities and market-corroborated inputs.  See Note 5 for discussion regarding our Propane Swaps.

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 nine months ended September 30, 2012.

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 (Loss) Per Common Unit

Net income (loss) 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 (loss) 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 (loss) for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income (loss) be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income (loss) as if all of the net income (loss) for the period had been distributed in accordance with the partnership agreement. Restricted units granted under the PetroLogistics Long-Term Incentive Plan (the Long-Term Incentive Plan) are eligible for Unit Distribution Rights (UDRs). To the extent that non-forfeitable UDRs are awarded, the underlying nonvested restricted units are considered participating securities for purposes of determining net income (loss) per unit.  Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and restricted units 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 restricted units as they do not participate in net losses.  Distributions 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 (loss).  Prior to the Offering, we were wholly-owned by Propylene Holdings.  Accordingly, net income (loss) per common unit is not presented for periods prior to the Offering.

The following table provides a reconciliation of net income (loss) and the allocation of net income to the common units and the restricted units for purposes of computing net income (loss) per unit for the three months ended September 30, 2012, (in thousands, except per unit data):

Recently Issued Accounting Standards

In May 2011, the FASB issued new guidance for fair value measurements intended to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards (IFRS). The amended guidance provides a consistent definition of fair value to ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. The amended guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. We adopted the new fair value measurement guidance on January 1, 2012, and the adoption did not have a material impact on our financial position or results of operations.

                In June 2011, the FASB issued guidance that modified how comprehensive income is presented in an entity’s financial statements. The guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of equity. We adopted the guidance pertaining to the presentation of other comprehensive income as of January 1, 2012, and the adoption did not have an impact on our financial statements or results of operations.

In December 2011, the FASB issued an accounting standards update on disclosures for offsetting assets and liabilities. The new accounting guidance requires companies to disclose both gross and net information about (1) instruments and transactions eligible for offset in the statement of financial position, and (2) instruments and transactions subject to an agreement similar to a master netting arrangement. The accounting standards update will be effective for reporting periods beginning on or after January 1, 2013, and is not expected to have a significant impact on our financial position or results of operations.

3. Initial Public Offering

On May 4, 2012, our common units began trading on the New York Stock Exchange under the symbol “PDH.” On May 9, 2012, we completed our Offering of 35,000,000 common units representing limited partner interests. Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings sold 33,500,000 common units at a price to the public of $17 per common unit ($15.98 per common unit, net of underwriting discounts).  Immediately prior to the Offering, the outstanding limited partner interests in the Partnership were recapitalized into 139,000,000 common units pursuant to an amended and restated limited partnership agreement.  We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts.  For further information related to the Offering, refer to our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.  The underwriters to the Offering did not exercise their rights to purchase additional common units.

5. Derivative Instruments

Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011, 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, a calculation is performed 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 exceeds the contractual percentage under the Propane Swaps, we are owed a sum by the Propane Swaps counterparty. If the contractual percentage exceeds the actual percentage under the Propane Swaps, we owe a sum to the Propane Swaps counterparty. In March 2012, to offset the negative impact of the liability position of our Propane Swaps, we entered into reverse positions for a portion of our Propane Swaps maturing in the second half of 2013. These reverse positions resulted in an asset and are reflected as derivative assets in our consolidated balance sheet at September 30, 2012.

Under the Omnibus Agreement and the Pledge Agreement, any amounts received by the Partnership under the Propane Swaps will be distributed to PL Manufacturing and the PL Manufacturing Members, and any amounts that the Partnership is required to pay under the Propane Swaps will be contributed to the Partnership as a capital contribution by PL Manufacturing and the PL Manufacturing Members. See Note 2 regarding the Omnibus Agreement.

As of September 30, 2012, we had entered into the following outstanding commodity forward contracts to hedge our forecasted energy commodity purchases:

	Volume(1)
	Settlement date
Derivatives not designated as hedging contracts	2012	2013(2)
Propane Swaps, net	1.38 MMBbls	3.83 MMBbls

(1)Volume reflects the absolute value of derivative notional volumes.

(2)The maximum term for derivatives included in the 2013 column is December 2013.

The 2012 and 2013 volumes of 1.38 and 3.83 million barrels (MMBbls) reflect hedged volumes of 15,000 and 11,000 barrels of propane per day, respectively, for each of the years presented with 2013 volumes reduced by a reverse position of 1,000 barrels of propane per day or 0.18 MMBbls for the second half of 2013.

Fair Value of Derivative Contracts

The fair values of our current and non-current derivative contracts are each reported separately on our balance sheets. The following table summarizes the fair values of our derivative contracts included on our balance sheets (in thousands):

Propane Swaps	$	21,114		$	163,684
Total	$	21,114		$	163,684

There was no activity related to the Propane Swaps in the three or nine months ended September 30, 2011.

Credit Risks

We have counterparty credit risk because the counterparty for all of our derivative contracts is one financial institution. This concentration in one counterparty may impact our overall exposure to credit risk in that the counterparty may be singularly affected by changes in economic, regulatory or other conditions, and our credit risk will not benefit from the benefits of a more diversified group of counterparties.

We maintain credit policies with regard to our counterparty that we believe minimize our overall credit risk. These policies include an evaluation of the counterparty’s financial condition (including credit ratings). Based on our policies and exposure, our management does not anticipate counterparty non-performance and, as a result, no material adverse effect on our financial position, results of operations, or cash flows.

Our derivative contracts are entered into outside of central trading organizations such as futures, options or stock exchanges. These contracts are entered into with a counterparty and, are guaranteed by a parent with an investment grade credit rating. While we enter into derivative transactions with an investment grade counterparty and actively monitor credit ratings, it is nevertheless possible that from time to time losses will result from counterparty credit risk in the future. Our derivative contracts do not permit master netting arrangements at this time.

Prior Credit Facility

We entered into a five-year credit facility agreement in June 2009 that included a $150.0 million construction loan commitment and a $55.0 million revolving credit facility (the prior credit facility). In May 2011 the construction loan was converted to a term loan with principal and interest due quarterly thereafter following the successful completion of a series of tests demonstrating successful operating performance of the Facility as required by the terms of our prior credit facility. In October 2011, the term loan was amended to require monthly principal and quarterly interest payments beginning in January 2012. On March 27, 2012, we refinanced and canceled the prior credit facility with borrowings under a new term loan facility.

New Credit Facilities

On March 27, 2012, PL Propylene, entered into a new term loan facility of $350.0 million and a new revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc. (the Agent), and the lenders party thereto (together, the new credit facilities). We drew $350.0 million under the new term loan facility and used (1) $60.8 million to refinance and cancel our prior credit facilities, (2) $250.0 million to reimburse our Sponsors for construction capital expenditures and (3) approximately $16.5 million to pay associated financing costs and debt discounts. PL Propylene used the remaining amount (approximately $22.7 million) for general partnership purposes. The new term loan included a discount of $7.0 million, which is reported net, less related amortization, against the total outstanding debt in our consolidated balance sheet at September 30, 2012.  The discount is being amortized over the term of the new term loan using the straight-line method, which approximates the effective interest method. We also have the right to add, subject to certain restrictions and conditions, incremental term loan and revolving credit facilities in an amount not to exceed $50.0 million.

The new credit facilities contain certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement to maintain a Total Secured Leverage Ratio, as defined, no greater than 4.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2012, the aggregate amounts outstanding under the new revolving credit facility exceed $100.0 million. At September 30, 2012, no amounts were outstanding, and we had $120.0 million available to us under the new revolving credit facility. The new credit facilities are secured by substantially all of PL Propylene’s assets.

Interest Rate and Fees.     Borrowings under the new credit facilities bear interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the new term loan facility and the revolving credit facility ranges from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. At September 30, 2012, the interest rate on the new term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

The new revolving credit facility also includes a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the new revolving credit facility.  In addition, we pay an annual management fee for our new term loan facility and our new revolving credit facility. We are 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 5.75%, and 0.125%, respectively.

Amortization and Final Maturity.     The new term loan facility will be amortized in aggregate amounts of 0.25% per fiscal quarter of the original principal amount and will mature on the fifth anniversary of the closing date, March 27, 2017. The new revolving credit facility maturity date is September 27, 2016, at which time the new revolving credit facility will terminate.

In connection with the refinancing, we wrote off approximately $7.0 million of unamortized deferred financing costs associated with the prior credit facility. The write-off of these costs is reflected as a loss on early extinguishment of debt in our consolidated statement of comprehensive income (loss) for the nine month period ended September 30, 2012.

As required by our new 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 new term loan. The agreement terminates March 27, 2014.

7. PL Manufacturing Profits Interest Plan

Prior to the Offering, PL Manufacturing maintained a profits interest plan (the Profits Interest Plan) for the benefit of our employees, as well as the key management employees of certain affiliated companies (collectively, Management). Because the Profits Interest Plan was intended to compensate Management with respect to the services they performed for our benefit, the equity-based compensation expense is reflected in our financial statements.

PetroLogistics Company LLC (PetroLogistics LLC) is an entity owned by David Lumpkins and Nathan Ticatch. Through December 31, 2011, the senior executives who oversee our operations were employed by PetroLogistics LLC and provided management services to us pursuant to our services agreement with PetroLogistics LLC. The majority of the profits interests (Profits Interest Units) that PL Manufacturing issued were to persons employed by PetroLogistics LLC. For accounting purposes, we treated these awards as being made to non-employees through December 31, 2011. As of January 1, 2012, all PetroLogistics Company LLC employees transferred their employment to the General Partner. As of that date, the underlying grant date fair value of nonvested Profits Interest Units held by the former PetroLogistics LLC employees became fixed due to the change in employment status, and equity-based compensation expense attributed to these Profits Interest Units for the nine months ended September 30, 2012, was based on the underlying fair value of the Profits Interest Units as of January 1, 2012.

Vesting and Unit Rights

Under the Profits Interest Plan, Class B, C and D Profits Interest Units were granted to management and employees.  The Class B Profits Interest Units were fully vested at the date of issuance, July 23, 2008. The issued and outstanding Class C and Class D Profits Interest Units vested over four years beginning on the later of March 11, 2009, or the recipient’s date of employment. The Class C and Class D Profits Interest Units became fully vested upon the closing of the Offering in May 2012.  There were no forfeitures for any of the periods presented. At the closing of the Offering, remaining unrecognized compensation expense related to the previously nonvested Profits Interest Units was recognized in the amount of approximately $43,710,000.

Determination of Equity-Based Compensation Expense

Equity-based compensation expense for all equity-based awards issued to employees was based on the estimated grant-date fair value of the Profits Interest Units. We recognized this equity-based compensation expense on a straight-line basis over the requisite service period of the award for those Profits Interest Units that were expected to vest. For Profits Interest Units granted to non-employees, non-vested Profits Interest Units were revalued at the reporting date fair value, with any change in value reflected in the statements of comprehensive income (loss).

Total recognized equity-based compensation expense related to the Profits Interest Plan was as follows (in thousands):

8. Long-Term Incentive Plan

2012 Long-Term Incentive Plan

The Long-Term Incentive Plan has been adopted by our General Partner. 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.

Restricted Unit Awards

A restricted unit award under the Long-Term Incentive Plan is a common unit that vests over a period of time and during that time is subject to forfeiture. Our General Partner anticipates that the majority of our restricted units will generally vest annually over a three-year period from the date of grant provided the recipient has continuously provided services to us, our General Partner, or any other of our affiliates.

Certain restricted unit awards are eligible for UDRs. Absent any restrictions on the UDRs in an award agreement, we will pay UDRs to the holder of the restricted unit without restriction at the same time as we pay quarterly cash distributions to our common unitholders. To the extent provided by the Long-Term Incentive Plan’s Administrative Committee (the Committee), in its discretion, a grant of restricted units may provide that distributions made with respect to the restricted units shall be subject to the same forfeiture and other restrictions as the underlying restricted unit and, if restricted, such distributions shall be held, without interest, until the restricted unit vests or is forfeited with the UDR being paid or forfeited at the same time, as the case may be. In addition, the Committee may provide that such distributions be used to acquire additional restricted units for the participant. Such additional restricted units may be subject to such vesting and other terms as the Committee may prescribe.

During the three months ended September 30, 2012, we recognized total equity-based compensation expense of approximately $777,000 related to the restricted unit awards ($507,000 as cost of sales and $270,000 as general and administrative expense). During the nine months ended September 30, 2012, we recognized total equity-based compensation expense of approximately $1,244,000 related to the restricted unit awards ($822,000 as cost of sales and $422,000 as general and administrative expense.

The following table presents activity related to our Long-Term Incentive Plan awards granted to employees during the nine months ended September 30, 2012:

	Restricted Unit Awards		Weighted average grant date fair value
Units outstanding December 31, 2011	—		$	—
Units granted	576,539		16.60
Units forfeited	(15,772	)	16.60
Units outstanding September 30, 2012	560,767		$	16.60

These service-based awards vest ratably over three years.  At September 30, 2012, none of the restricted unit awards were vested.  The aggregate intrinsic value of outstanding restricted unit awards at September 30, 2012, was approximately $7,273,000. Also at September 30, 2012, total compensation cost related to nonvested restricted employee unit awards that had not yet been recognized totaled approximately $8,076,000.  The weighted-average period over which this amount will be recognized is approximately 2.6 years.

The following table presents activity related to our Long-Term Incentive Plan awards granted to members of our General Partner’s Board of Directors during the nine months ended September 30, 2012:

	Restricted Unit Awards	Weighted average grant date fair value

Units granted	16,182	12.36
Units forfeited	—	—
Units outstanding September 30, 2012	16,182	$	12.36

These awards vest ratably over one year.  At September 30, 2012, none of the restricted unit awards were vested.  The aggregate intrinsic value of outstanding restricted director unit awards at September 30, 2012, was approximately $210,000. Also at September 30, 2012, total compensation cost related to nonvested restricted director unit awards that had not yet been recognized totaled approximately $189,000  The weighted-average period over which this amount will be recognized is approximately 0.8 years.

Services Agreement with PetroLogistics GP LLC

We entered into a services agreement with our General Partner on January 1, 2012, pursuant to which our General Partner provides certain operational, managerial and general administrative services to us.  All employees of PL Propylene and PetroLogistics LLC became employees of our General Partner on January 1, 2012.  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.  The amounts we pay the General Partner for these services are reported in the statements of comprehensive income (loss) in the line item to which the expense relates.

First Amended and Restated Agreement of Limited Partnership of PetroLogistics LP

On May 3, 2012, in connection with the completion of the Offering, our General Partner amended and restated our partnership agreement and executed the First Amended and Restated Agreement of Limited Partnership of PetroLogistics LP (the Partnership Agreement), which governs the rights of our partners. Among others, revisions included the recapitalization of our common units in connection with the Offering and provisions regarding allocations and distributions. The full text of the Partnership Agreement can be found in our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.

Indemnification Agreement

The Partnership Agreement provides that each of our directors and officers may receive indemnification for actions associated with being a director or officer in order to enhance the indemnification rights provided under Delaware law and the Partnership Agreement. The Partnership Agreement provides each such director or officer with rights to receive his or her costs of defense if the individual is a party or witness to any proceeding other than a proceeding brought by or in the right of, us, provided that such director or officer has not acted in bad faith or engaged in fraud with respect to the action that gave rise to his or her participation in the proceeding.

Other

During the nine months ended September 30, 2012 and 2011, we utilized the services of a company owned by Lindsay Goldberg in the amounts of approximately $1,115,000 and $1,972,000, respectively, in connection with Facility maintenance activities.

In 2011, we entered into an agreement with Lindsay Goldberg, under which we were to pay an annual fee of $2,000,000 for advisory services. This agreement terminated under its terms with the Offering. At the closing of the Offering, we owed Lindsay Goldberg approximately $2,667,000 related to this fee. This amount was waived by Lindsay Goldberg in May 2012 in connection with the Offering, and the accounts payable-related party was reversed at that time with a corresponding increase in partners’ capital.

10. 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				Nine Months
	Ended				Ended
	September 30,				September 30,
	2012		2011		2012		2011
Dow Chemical Company (Dow)	36	%	60	%	42	%	54	%
Total Petrochemicals USA, Inc. (Total)	20	%	18	%	20	%	24	%
INEOS Olefins and Polymers USA (INEOS)	22	%	15	%	18	%	16	%
LyondellBasell Industries N.V. (LyondellBasell)	14	%	0	%	11	%	1	%
Others (less than 10% individually)	8	%	7	%	9	%	5	%
Total sales	100	%	100	%	100	%	100	%

We have entered into market-based sales contracts with our propylene customers to provide minimum annual quantities. (see Note 11). These minimum quantities comprise the substantial majority of the 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 are unable to meet our production requirements if we are unable to locate and procure replacement volumes from alternate sources.

Counterparty Risk with Respect to Derivative Instruments

Our business activities expose us to the risk associated with changes in the market price of propylene and propane. In order to manage our exposure to the price risk related to propane, we began entering into derivative contracts in October 2011. The derivative contracts permit us to economically hedge a portion of our expected propane needs for 2012 and 2013 (see Note 5).

In those situations where we are exposed to credit risk in our derivative instruments transactions, we analyze the counterparty’s financial condition prior to entering into an agreement. Generally, we do not require collateral nor do we anticipate nonperformance by our counterparty.

that these proceedings, when resolved, will not have a material adverse effect on our results of operations, financial position, or liquidity.

12. Subsequent Events

The fair value of our Propane Swap assets decreased from approximately $2.4 million to approximately $1.8 million, and our Propane Swap liabilities decreased from approximately $94.7 million to approximately $65.1 million on October 31, 2012 ($58.0 million current liability and $7.1 million non-current liability), representing an unrealized gain on derivatives of $29.0 million. We also incurred a realized loss on derivatives of approximately $9.6 million in October 2012. Also, see Note 2 regarding the Omnibus Agreement related to our Propane Swaps.

On October 24, 2012, the General Partner approved a distribution to common unitholders of record as of November 5, 2012. The distribution of 21 cents per common unit will be paid on November 14, 2012. PL Manufacturing and the PL Manufacturing Members are required by the Omnibus Agreement to contribute approximately $31.0 million to partially fund their obligation for realized losses on the Propane Swaps through a reduction in the cash distribution payable to them with the remaining portion funded with a cash payment of approximately $9.2 million from PL Manufacturing and the PL Manufacturing Members. We expect to receive payment of the contribution in November 2012, and the entire contribution of $31.0 million is reflected as a related party receivable in our consolidated balance sheet at September 30, 2012.

Initial Public Offering

On May 4, 2012, our common units began trading on the NYSE under the symbol “PDH.” On May 9, 2012, we completed our Offering of 35,000,000 common units representing limited partner interests.  Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings LLC sold 33,500,000 common units at a price to the public of $17.00 per common unit ($15.98 per common unit, net of underwriting discounts).  Immediately prior to the Offering, the outstanding limited partner interests in the Partnership were recapitalized into 139,000,000 common units pursuant to an amended and restated limited partnership agreement.  We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts.

Overview

We currently own and operate the only U.S. propane dehydrogenation (PDH) facility (the Facility) producing propylene from propane. Propylene is one of the basic building blocks for petrochemicals that is utilized in the production of a variety of end uses including paints, coatings, building materials, clothing, automotive parts, packaging and a range of other consumer and industrial products. Our Facility has an annual production capacity of approximately 1.4 billion pounds of propylene. We commenced operations in October 2010 and, after an approximately year-long start-up and plant optimization phase, achieved production rates at or near current capacity beginning in December 2011.

We currently have multi-year contracts for the sale of our propylene with The Dow Chemical Company, Total Petrochemicals USA, Inc., BASF Corporation and INEOS Olefins and Polymers USA that expire between 2013 and 2018 and a one-year contract with LyondellBasell Industries N.V. that ends in December 2012. The contracts provide for minimum and maximum offtake volumes, with the minimum customer-contracted volumes representing approximately 75% of our current Facility capacity and the maximum reflecting approximately 100% of our current Facility capacity. For the three and nine months ended September 30, 2012, four of our customers accounted for 92% and 91%, respectively, of our total sales. Each of our customer contracts contains pricing terms based upon market rates. We have supplied and will continue to opportunistically supply other propylene consumers on a spot basis when permitted by both operational and market conditions.

In addition to propylene, we also produce commercial quantities of hydrogen and C4 mix/C5+ streams. These products represented approximately 3% to 4% of total sales in the three and nine months ended September 30, 2012, and do not represent a material part of our production.

Factors Affecting the Comparability of Future Results

Our historical results of operations and cash flows are not indicative of results of operations and cash flows to be expected in the future, principally for the following reasons:

·Our PDH Facility did not generate sales until we commenced operations in October 2010. We commenced operations in October 2010 and, after an approximately year-long startup and plant optimization phase, achieved production rates at or near current capacity beginning in December 2011. Accordingly, our financial statements for the three and nine months ended September 30, 2011, reflect limited operations.

·Our historical results of operations reflect equity-based compensation expense that may not be indicative of future equity-based compensation expense. Our historical results of operations reflect equity-based compensation expense for both our employees and certain employees of affiliated entities, who are treated for accounting purposes as non-employees. As of January 1, 2012, all PetroLogistics Company LLC employees became employees of our General Partner and are treated as employees for accounting purposes. Equity-based awards granted to non-employees are subject to periodic fair value adjustments as the awards vest. The changes in fair value are recognized in our statement of comprehensive income (loss) during the period the related services are rendered, resulting in greater

26

volatility of our results of operations. Because certain members of our senior management were treated as non-employees for accounting purposes prior to January 1, 2012, these fair value adjustments have significantly affected our historical results of operations. The equity-based awards outstanding at the time of the Offering became fully vested as of the completion of the Offering, and we recorded equity-based compensation expense of $43.7 million in the second quarter of 2012. No additional expense related to these awards was recorded during the third quarter of 2012 or will be recorded in the future. However, we intend to make future equity-based compensation awards pursuant to our long-term incentive plan, which will again require us to record equity-based compensation expense.

·We will incur additional general and administrative expenses as a publicly traded partnership. We expect we will incur additional general and administrative expenses as a publicly traded limited partnership that we have not previously incurred, including costs associated with compliance under the Exchange Act, annual and quarterly reports to unitholders, tax return and Schedule K-1 preparation and distribution, investor relations, registrar and transfer agent fees, audit fees, incremental director and officer liability insurance costs and directors’ compensation. In addition, we will incur incremental expenses associated with the initial implementation of our Sarbanes-Oxley Section 404 internal control reviews and testing as well as the costs associated with a change in our accounting information systems.

·Our historical results of operations reflect allocated administrative costs that may not be indicative of future administrative costs. Our 2011 combined financial statements included certain costs of a formerly affiliated company that were incurred on our behalf. Historically, these costs, which are reflected in general and administrative expense, have been billed to us pursuant to a services agreement entered into in 2008 (the former services agreement). Our financial statements, therefore, include certain expenses incurred which may include, but are not necessarily limited to, executive management and employee salaries and benefits, travel and entertainment expenses, rent and other general and administrative expenses. Such expenses were allocated to us based upon certain assumptions and estimates that were made in order to allocate a reasonable share of such expenses from the formerly affiliated company to us so that our financial statements would reflect substantially all the costs of conducting our business. The former services agreement terminated at the end of 2011. We entered into a services agreement with our General Partner on January 1, 2012, pursuant to which the General Partner provides certain operational, managerial and general administrative services to us.  All employees of PL Propylene and the formerly affiliated company became employees of our General Partner on January 1, 2012.  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.  The amounts we pay the General Partner for these services are reported in the statements of comprehensive income (loss) in the line item to which the expense relates.  The amounts charged or allocated to us under the former and current services agreements are not necessarily indicative of the costs that we will incur going forward.

·We will periodically experience planned and unplanned downtime. Safe and reliable operations at our Facility are critical to our performance and financial results. As such, we expect future periods of major maintenance. We do not expect to undergo a major maintenance project until the second half of 2013, at which time the most significant activity will be to replace the reactor catalyst, which is required approximately every three years based on facilities of similar design. We expect these catalyst change-out projects will typically last approximately four weeks. In addition to the triennial maintenance projects, more significant maintenance projects will be undertaken approximately every nine years and will include change-out of the reactor catalyst and overhauls of selected pieces of equipment. We anticipate these projects to take approximately six weeks. Additionally, we may undertake capital projects in connection with major maintenance projects. If we elect to undertake such projects, these capital projects will require additional time and expense.

27

In addition to planned downtime for major maintenance projects, we may experience periods of unplanned downtime. We expect to be able to mitigate the financial and operational impact of unplanned downtime through a targeted program of routine maintenance and diligent monitoring of our systems. Downtime, whether planned or unplanned, will result in lost sales and margin, increased capital and maintenance expenditures and/or working capital changes.

·We may enter into different financing arrangements. Our current financing arrangement may not be representative of the arrangements we will enter into in the future. For descriptions of our current financing arrangements, see “—Liquidity and Capital Resources.”

Factors Affecting Results

We believe key factors that influence our business and impact our operating results are (1) the propane-to-propylene spread, (2) our Facility’s production capacity utilization and sales volume as a percentage of capacity and (3) our propane-to-propylene conversion factor.

Propane-to-Propylene Spread

The price spread between propane, our sole feedstock, and propylene, our primary product, largely determines our gross margin and is the key driver of our profitability.

Propylene sales constitute substantially all of our sales. Propylene is a commodity, and its price can be cyclical and highly volatile. The price of propylene depends on a number of factors, including general economic conditions, cyclical trends in end-user markets and supply and demand imbalances. The customers under our propylene sales contracts, (Dow, Total, BASF, INEOS and LyondellBasell) each pay market-based prices for propylene, and a significant decrease in propylene prices would have a material adverse effect on sales generated from these customers. In addition, a decrease in the price of propylene would result in decreased sales from any sales of propylene on the spot market.

Propane is the sole feedstock in our production process, and the cost of propane represents a substantial portion of our cost of sales. Enterprise supplies 100% of our required propane feedstock volume under a multi-year contract at market-based prices, which prices are subject to fluctuations in response to changes in supply, demand, market uncertainties and a variety of additional factors beyond our control. The contract with Enterprise expires in 2015. See “—Quantitative and Qualitative Disclosures about Market Risk.”

The propane-to-propylene spread is calculated as (PGP Contract Benchmark Price (¢/lb ) — 1.2* (Propane Price (¢/gl)/4.2)). This calculation assumes it takes approximately 1.2 pounds of propane to make 1.0 pound of propylene and one gallon of propylene weighs approximately 4.2 pounds.

Capacity Utilization

Our Facility has a current annual production capacity of approximately 1.4 billion pounds of propylene. Actual annual production will vary based on a number of factors, including the amount of downtime for planned and unplanned maintenance on the Facility and the amount of demand from our customers. Any significant planned or unplanned downtime will affect not only production, but also capital expenditures and direct operating expenses, primarily maintenance expenses, and fuel and utilities. Unplanned downtime may also affect our sales, and demand from our customers will affect our sales volume as a percentage of capacity.

Propane-to-Propylene Conversion Factor (Monomer Factor)

An important contributor to profitability is our propane-to-propylene conversion factor, which is a ratio that indicates how much propane is used to produce one pound of propylene. We expect to have an average monthly propane-to-propylene

28

conversion factor of 1.0 pound of propylene for each 1.2 pounds of propane used. This important statistic reflects our Facility’s operating efficiency.

How We Evaluate Our Performance

In addition to utilizing the key factors affecting our operating results described above to evaluate our performance, our management uses certain additional financial and operational measures as well. These measures include Adjusted EBITDA and health, safety and environmental performance.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) plus interest expense and amortization of deferred financing costs (including loss on early extinguishment of debt), income tax expense, depreciation, amortization and accretion, equity-based compensation expense, unrealized loss on derivatives and, effective May 9, 2012, realized gains and losses on derivative contracts. Pursuant to an Omnibus Agreement among our General Partner, the Partnership, Propylene Holdings LLC (Propylene Holdings), PL Propylene, and PL Manufacturing LLC (PL Manufacturing) (the Omnibus Agreement) to the extent we make payments on our commodity derivative contracts (the Propane Swaps), PL Manufacturing and the PL Manufacturing Members, through our General Partner, will be responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we make under such Propane Swaps during the applicable fiscal quarter or that we owe at the end of the quarter resulting in a capital contribution to us and a zero net effect on cash and partners’ capital. Adjusted EBITDA is a non-U.S. GAAP financial measure that may be used by our management and by external users of our financial statements, such as industry analysts, investors, lenders and rating agencies, to assess:

·the ability of our assets to generate sufficient cash flow to make distributions to our unitholders;

·evaluate the financial performance of our assets without regard to financing methods, capital structure, or historical cost basis; and

·determine our ability to incur and service debt and fund capital expenditures.

29

We view Adjusted EBITDA as an important indicator of cash flow generation. Adjusted EBITDA is principally affected by our sales volumes, the propane-to-propylene spread, capacity utilization, propane-to-propylene conversion factors and, to a lesser extent, the prices of natural gas and our by-products. Other than the cost of propane and natural gas, production-related expenses generally remain stable across broad ranges of throughput volumes, but can fluctuate significantly depending on the planned and unplanned maintenance performed during a specific period. Our Adjusted EBITDA and available cash may not always correlate to each other.

Adjusted EBITDA should not be considered an alternative to net income (loss), operating income (loss), cash flows from operating activities or any other measure of financial performance presented in accordance with U.S. GAAP. Our Adjusted EBITDA may not be comparable to Adjusted EBITDA or similarly titled measures of other entities, as other entities may not calculate Adjusted EBITDA in the same manner as we do. Our management compensates for the limitations of Adjusted EBITDA as an analytical tool by reviewing the comparable U.S. GAAP measures, understanding the differences between the measures and incorporating this knowledge into management’s decision-making processes. Adjusted EBITDA should not be viewed as indicative of the actual amount we have available for distributions or that we plan to distribute for a given period, nor should it be equated with “available cash” as defined in our Partnership Agreement.

The following table reconciles net income (loss) to Adjusted EBITDA for the periods indicated (in thousands):

(1) Effective May 9, 2012, pursuant to the Omnibus Agreement, to the extent that we make payments for realized losses under the Propane Swaps, PL Manufacturing and the PL Manufacturing Members, through our General Partner, will be responsible for making quarterly capital contributions to us in an amount equal to the sum of all payments we make under such Propane Swaps during the applicable fiscal quarter or that we owe at the end of the quarter. The amount of realized loss on derivatives shown as an adjustment for EBITDA represents the amount received or to be received from PL Manufacturing and the PL Manufacturing Members. See discussion of the Omnibus Agreement in Note 2 to our combined financial statements included elsewhere in this report.

Health, Safety and Environmental Performance

We consider our ability to manage our Facility and customer needs in a safe and reliable manner to be a critical factor in assessing our performance. Accordingly, we have an extensive training program and set annual goals on achieving operating performance and safety measures that assure the reliable operation of our Facility and a safe working environment for our employees. Further, we closely monitor all environmental metrics to assure compliance with all regulatory requirements and that we operate in an environmentally responsible manner.

Results of Operations

The period-to-period comparisons of our results of operations have been prepared using the historical periods included in our consolidated financial statements. In order to effectively review and assess our historical financial information below, we have also included a description of the components of the various financial statement line items.

Sales.  Sales are comprised of propylene sales and by-product sales, which include hydrogen and C4 mix/C5+ streams.

Cost of Sales.  Cost of sales represents the costs of propylene and by-products sold. These costs include the cost of propane, fuel and utilities used in the propylene production process, as well as direct operating expenses and insurance and property tax expenses associated with our Facility. Direct operating expenses include all direct and indirect labor at our Facility, materials, supplies, and other expenses associated with the operation and maintenance of the Facility. Depreciation, amortization and accretion expenses, exclusive of amortization of deferred financing fees, are also included within cost of sales. During periods in which our Facility operates below normal capacity, we record charges to cost of sales to reflect unabsorbed fixed overhead costs.

                General and Administrative Expense.  General and administrative expense includes salary and benefits costs for executive management, accounting and information technology personnel, as well as legal, audit, tax and other professional service costs and charges for equity-based compensation expense. In 2011, a portion of these costs were billed to us by an affiliated company pursuant to the former services agreement. As of January 1, 2012, these services are provided under a services agreement with our General Partner.

30

Management Fee.  Management fee consists of the expense incurred through our advisory services agreement with Lindsay Goldberg LLC. This agreement terminated upon the closing of the Offering.

Loss on Derivatives.  Our derivative contracts are recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet. Our derivative contracts do not qualify for hedge accounting treatment. Consequently, the associated unrealized gains and losses are recorded as current expense or income in the statement of comprehensive loss. Unrealized gains or losses on derivatives represent the non-cash change in the fair value of these derivative instruments and do not impact operating cash flows until settlement occurs in 2012 and 2013.

Interest Expense, Net.  Interest expense includes expense incurred on outstanding debt balances, the amortization of loan discount and deferred financing fees and loan commitment expenses under our credit facilities. Loan commitment expense is comprised of the fees assessed on the unutilized portion of our credit facility. Interest income results from earnings on available cash balances and is offset against interest expense.

Other Income.  Other income has historically been generated through the sale of certain equipment.

Income Tax Expense.  As an entity operating in the State of Texas, we are subject to the Texas Margin Tax. This tax represents a tax on gross margin, as adjusted, and is reported as income tax benefit (expense) in the accompanying statements of comprehensive loss.

Sales.  For the third quarter of 2012, we produced 312 million pounds of propylene compared to 253 million pounds of propylene produced during the third quarter of 2011, which represents an increase in production of 23%. This increase in production is due to our Facility having less downtime in the third quarter of 2012 compared to the downtime in second quarter of 2011 caused by startup issues.  For the three months ended September 30, 2012 and 2011, we recognized sales of 318 million and 222 million pounds of propylene, respectively, an increase of 43%. The Facility’s first full month of polymer grade propylene (PGP) production was September 2011 whereas the third quarter of 2012 had three full months of PGP production. The average polymer grade contract benchmark propylene price in the three months ended September 30, 2012, was 51.3 cents per pound compared to an average of 78.0 cents per pound for the three months ended September 30, 2011, a price drop of 26.7 cents per pound or 34%. The increase in propylene sales is a result of the increase in the volume of propylene sold, offset by lower contract propylene prices in the third quarter of 2012 compared to 2011.

Cost of sales	$	117,996	$	131,332		$	(13,336	)	(10	)

Cost of sales was $118.0 million for the three months ended September 30, 2012, compared to $131.3 million for the three months ended September 30, 2011. The primary component of cost of sales is the propane feedstock, which represented 72% of total production costs for the three months ended September 30, 2012, compared to 78% for the comparable 2011 period. Despite higher propane usage, propane expense decreased 27% in the third quarter of 2012 compared to 2011. This result is due to a 42% drop in propane prices for the third quarter of 2012 compared to 2011. The average propane price was 89.3 and 153.8 cents per gallon for the third quarter of 2012 and 2011, respectively.

The change in inventory represents the change in the production value of the product inventory between the beginning and end of the period based on the weighted average cost of production. This amount fluctuates with our average cost of production and the amount of product inventory we carry.

Gross Profit. For the quarter ended September 30, 2012, we had a gross profit of $38.1 million compared to $36.4 million in the comparable quarter of 2011. The increase in gross profit was a result of increased propylene volumes offset by a decrease in the propane-to-propylene spread to 25.9 cents for the third quarter of 2012 from 34.1 cents per pound for the comparable 2011 period.

General and Administrative Expense.   General and administrative expense was $8.7 million for the three months ended September 30, 2012, compared to $7.1 million for the three months ended September 30, 2011, an increase of $1.6 million. The increase is primarily attributable to project development expense of $5.7 million in the three months ended September 2012 incurred on potential future capital projects which do not yet qualify for capitalization under U.S. GAAP because of the preliminary stage of these projects. This increase was offset by a decrease of $4.6 million in non-cash equity-based compensation expense recognized in the third quarter of 2011 which was attributable to equity-based awards granted in 2010 to both our employees and certain employees of affiliated entities.

Management Fee.  In 2011, we entered into an agreement with Lindsay Goldberg, under which we were to pay an annual fee of $2 million for advisory services.  This agreement terminated under its terms with the completion of the Offering.

Loss on Derivatives. Commencing October 2011, we entered into 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.  For the quarter ended September 30, 2012, we recognized $31.0 million of realized losses and $9.9 million of unrealized gain under the Propane Swaps. Unrealized gain on the Propane Swaps represents the non-cash change in the fair value of the Propane Swaps and does not impact operating cash flows. Until settlement occurs, this will result in non-cash gains or losses being reported in our results of operations as the Propane Swaps do not qualify for hedge accounting treatment.

Interest Expense, Net.   Interest expense on borrowings of $6.2 million was incurred for the three months ended September 30, 2012, on an average daily debt balance of $349.4 million. For the three months ended September 30, 2011, we incurred $3.0 million in interest expense on borrowings on an average debt balance of $150.0 million. 

Income Tax Benefit (Expense).   For the third quarter of 2012 we recognized net income tax expense of $0.2 million compared to income tax expense of $0.4 million in the third quarter of 2011. Our income tax expense solely relates to income taxes incurred on gross margin with the State of Texas.

Sales.    For the nine months ended September 30, 2012 we produced 967 million pounds of propylene compared to 620 million pounds of propylene produced during the 2011 year-to-date period, which represents an increase in production of 56%. During the nine months ended September 30, 2011, we had not yet achieved production rates at or near current capacity. In addition, our Facility experienced periods of significant downtime in the first nine months of 2011 related to Facility startup issues. Accordingly, production and sales were lower during that period.

Cost of sales was $408.0 million, or approximately 70% of sales, for the nine months ended September 30, 2012, compared to $350.5 million or, 75% of sales, for the nine months ended September 30, 2011. The primary component of cost of sales is the propane feedstock, which represented 77% and 74% of total production costs for the nine months ended September 30, 2012 and 2011, respectively. The increase in propane expense in 2012 over the nine months ended September 30, 2011, is due to the higher production volumes in 2012 offset by lower propane prices. The decrease in fuel and utilities expense is primarily due to a 42% increase in natural gas volumes used in production offset by a decrease in natural gas prices from 2011 to 2012.

The change in inventory represents the change in the production value of the product inventory between the beginning and end of the period based on the weighted average cost of production. This amount fluctuates with our average cost of production and the amount of product inventory we carry.

General and Administrative Expense.    General and administrative expense was $68.5 million for the nine months ended September 30, 2012, compared to $54.0 million for the nine months ended September 30, 2011, an increase of $14.5 million. The increase is primarily attributable to an increase of $8.2 million in equity-based compensation expense and project development expense of $5.7 million incurred on potential future capital projects which do not yet qualify for capitalization under U.S. GAAP because of the preliminary stage of these projects. Also contributing to the increase is an increase of approximately $0.8 million in salaries and benefits resulting from an increased headcount associated with being a public company.

Management Fee.    We incurred management fees of $0.7 million for the nine months ended September 30, 2012, compared to $1.5 million for the nine months ended September 30, 2011. The management fees relate to an advisory services agreement pursuant to which we were to pay Lindsay Goldberg a total of $2.0 million per year, beginning in January 2011. The agreement and related management fees were terminated at the closing of the Offering.

Loss on Derivatives.  Commencing October 2011, we entered into 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.  Through September 30, 2012, we had recognized $73.0 million of realized losses and $90.7 million of unrealized losses under the Propane Swaps.

Interest Expense, Net.    Interest expense on borrowings of $15.5 million was incurred for the nine months ended September 30, 2012, on an average daily debt balance of $285.5 million. Interest expense on borrowings of $10.4 million was incurred on an average daily balance of $173.1 million for the nine months ended September 30, 2011, an increase of $5.1 million.

Loan commitment expense for the nine months ended September 30, 2012, was $0.9 million compared to $1.0 million for the nine months ended September 30, 2011. Also included in interest expense for the nine months ended September 30, 2012, is loan discount amortization of $0.7 million.

Loss on Early Extinguishment of Debt.  We recognized a loss on early extinguishment of debt of $7.0 million related to the termination and pay-off of our prior credit facility. See discussion under “Liquidity and Capital Resources.”

Income Tax Expense.    Income tax expense was $0.3 million for the nine months ended September 30, 2012, compared to $1.5 million for the nine months ended September 30, 2011, resulting from income taxes incurred on gross margin with the State of Texas. Lack of significant income tax expense for the nine months ended September 30, 2012, is due to a deferred tax benefit recorded for the temporary difference from the treatment of unrealized losses on derivatives for book purposes compared to the tax treatment. This benefit is reduced by current tax expense.

Critical Accounting Policies

The preparation of our financial statements in accordance with U.S. GAAP requires that management make estimates and assumptions affecting 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 period. There were no changes in our critical accounting policies for the period covered by this report.

35

Liquidity and Capital Resources

Prior to commencing operations in October 2010, our principal sources of liquidity historically were equity contributions from our Sponsors and borrowings under our prior credit facility. Beginning with the commencement of our operations in October 2010, our principal source of liquidity is cash flows from operations. Our principal uses of cash are expected to be operations, distributions, capital expenditures and funding our debt service obligations. We believe that our cash from operations will be adequate to satisfy commercial commitments for the next twelve months and that the borrowings under our new revolving credit facility will be adequate to fund our planned capital expenditures and working capital needs.

Our ability to make payments on our indebtedness, to make distributions, to fund planned capital expenditures and to satisfy our other capital and commercial commitments will depend on our ability to generate cash flow in the future. This, to a certain extent, is subject to the prevailing propane-to-propylene spread, propylene demand, propane supply levels, natural gas prices and general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. Our business may not generate sufficient cash flow from operations, and future borrowings may not be available to us under our new credit facilities in amounts sufficient to enable us to make quarterly distributions, finance necessary capital expenditures, service our indebtedness or fund our other liquidity needs. We may seek to sell assets or issue debt securities or additional equity securities to fund our liquidity needs but may not be able to do so. We may also need to refinance all or a portion of our indebtedness on or before maturity. We may not be able to refinance any of our indebtedness on commercially reasonable terms or at all.

On May 9, 2012, we, our General Partner, Propylene Holdings, PL Propylene and PL Manufacturing, entered into an 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 (together the PL Manufacturing Members).

Under the Omnibus Agreement and the Pledge Agreement any amounts we receive under the Propane Swaps will be distributed, through the General Partner, to PL Manufacturing and the PL Manufacturing Members, and any amounts that we are required to pay under the Propane Swaps is expected to be contributed back to us as a capital contribution by PL Manufacturing and the PL Manufacturing Members. During the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members contributed approximately $16 million to the Partnership as reimbursement for realized losses on the Propane Swaps pro-rated from May 9, 2012, the closing date of the Offering, through June 30, 2012.  The contribution was made in the form of a reduction in the cash distribution paid to PL Manufacturing and the PL Manufacturing Members.  For realized losses on the Propane Swaps in the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members will contribute approximately $31.0 million to the Partnership in November 2012 through a reduction in the cash distribution payable to them and a cash contribution of approximately $9.2 million.

While we do not receive any of the benefits of the Propane Swaps, we remain a party to the Propane Swaps, and are obligated to make payments to the Propane Swap counterparties as they come due and to post any collateral as required, under the terms of the Propane Swap agreement. To the extent that we make payments for realized losses under the Propane Swaps, PL Manufacturing and the PL Manufacturing Members, through our General Partner, will be responsible for making quarterly capital contributions in an amount equal to the net amount due to the Propane Swap counterparty for the applicable fiscal quarter.

We expect that PL Manufacturing and the PL Manufacturing Members will continue to fund their payment obligations primarily through quarterly distributions that they receive on common units that they own. Under the Pledge Agreement, the PL Manufacturing Members pledged to PL Manufacturing (as collateral agent) a number of common units such that at all times, the market value of all pledged units and all common units owned by PL Manufacturing that are subject to the Omnibus Agreement is equal to or greater than ten times the mark-to-market value of the Propane Swaps, but in no event shall the number of pledged units be greater than the amount of units distributed to PL Manufacturing and the PL Manufacturing Members in connection with the Offering. The expected aggregate quarterly distributions payable on all pledged common units are expected to be sufficient to cover future payments under the Propane Swaps, plus an additional reserve to be used for any cash payments, if necessary.

Initial Public Offering

On May 4, 2012, our common units began trading on the New York Stock Exchange under the symbol “PDH.” On May 9, 2012, we completed our Offering of 35,000,000 common units representing limited partner interests. Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings sold 33,500,000 common units at a price to the public of $17 per common unit ($15.98 per common unit, net of underwriting discounts). We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts. Offering costs totaled $5.5 million.  We did not receive any proceeds from the sale of common units by Propylene Holdings.

We intend to use the net proceeds of the Offering for working capital and general partnership purposes, for funding certain future capital expenditures at our Facility, including a portion of those associated with our planned major maintenance project in 2013 to replace the reactor catalyst, and for funding a portion of the distributions to our common unitholders for the lost margin resulting therefrom.

Prior Credit Facility

We entered into a five-year credit facility agreement in June 2009 that included a $150.0 million construction loan commitment and a $55.0 million revolving credit facility (the prior credit facilities). On March 27, 2012, we refinanced and canceled the prior credit facilities with borrowings under a new term loan facility.

New Credit Facilities

On March 27, 2012, PL Propylene entered into a new term loan facility of $350.0 million and a new revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc. (the Agent), and the lenders party thereto (together, the new credit facilities).

36

We drew $350.0 million under the new term loan facility and used (1) $60.8 million to refinance and cancel our prior credit facility, (2) $250.0 million to reimburse our Sponsors for construction capital expenditures and (3) approximately $16.5 million to pay associated financing costs and debt discounts. We used the remaining amount (approximately $22.7 million) for general working capital purposes. Borrowings under our new revolving credit facility may be used to fund our working capital needs and for other general partnership purposes as necessary. We also have the right to add, subject to certain restrictions and conditions, incremental term loan and revolving credit facilities in an amount not to exceed $50.0 million.

During the period from the date of the refinancing to September 30, 2012, we borrowed and repaid $21.7 million under the new revolving credit facility and repaid principal of $1.8 million on the new term loan facility. We also posted approximately $40.0 million as cash collateral with the Propane Swaps counterparty. At September 30, 2012, we had $120.0 million available under the new revolving credit facility.

Interest Rate and Fees.  Borrowings under the new credit facilities bear interest at a rate per annum based on an underlying base rate plus an applicable margin.  The applicable margin for the new term loan facility and the revolving credit facility ranges from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. At September 30, 2012, the interest rate on the new term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

The new revolving credit facility also includes a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the new revolving credit facility.  In addition, we pay an annual management fee for our new term loan facility and our new revolving credit facility. We are 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 5.75%, and 0.125%, respectively.

Prepayments.  The new credit facilities contain provisions for prepayment penalties if we prepay, refinance or reprice the term loan prior to the third anniversary of the closing date, March 27, 2015. We may not prepay, refinance or reprice the term loan facility on or prior to the first anniversary of the closing date, March 27, 2013.

37

Amortization and Final Maturity.  The new term loan facility amortizes in aggregate amounts of 0.25% per fiscal quarter of the original principal amount and will mature on the fifth anniversary of the closing date, March 27, 2017. The new revolving credit facility maturity date is September 27, 2016, at which time the new revolving credit facility will terminate.

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 new term loan. The agreement terminates March 27, 2014.

Capital Spending

During the nine months ended September 30, 2012, we incurred capital expenditures of $16.2 million, which includes approximately $5.1 million of progress payments towards the purchase of the reactor catalyst and related materials in preparation for the 2013 planned major maintenance project all of which was pre-funded by the pre-Offering investors, and $11.1 million for other capital projects of which $4.5 million was pre-funded by the pre-Offering investors.

During the nine months ended September 30, 2011, we incurred capital expenditures of $16.3 million primarily for plant modifications that improved the operating efficiency of our Facility.

38

In addition, during the nine months ended September 30, 2012, we purchased additional emissions credits for $9.3 million which are classified as other noncurrent assets in our consolidated balance sheet. We also incurred $5.7 million in project development expense during the quarter ended September 30, 2012, on future capital projects which do not yet qualify for capitalization under U.S. GAAP because of the preliminary stage of these projects. Of this amount, $5.5 million was pre-funded by the pre-Offering investors. This project development expense is classified as general and administrative expense in our consolidated statement of comprehensive income (loss).

Major planned turnaround costs will be deferred and amortized from the period incurred until the next turnaround. Certain capital expenditures are for discretionary projects. Our new term loan facility may limit the amount we can spend on capital expenditures.

Our future capital spending will be determined by the board of directors of our General Partner. We currently plan to incur capital expenditures of $42.5 million in 2012 and $41.1 million during 2013. The $41.1 million includes the capital required for our planned triennial plant turnaround in the second half of 2013, at which time the most significant activity will be to replace the reactor catalyst as well as other maintenance projects. We expect the turnaround projects will typically cost approximately $25 million to $30 million per project. In addition to the triennial turnaround projects, a more significant turnaround project will be undertaken approximately every nine years, which will include change-out of the reactor catalyst and overhauls of selected pieces of equipment.

Our estimated capital expenditures and planned turnaround project costs are subject to change due to unforeseen circumstances and unanticipated increases in the cost, scope and completion time. For example, we may experience increases in labor or equipment costs necessary to comply with government regulations or to complete projects that sustain or improve the profitability of our Facility.

Capital expenditures and planned turnaround projects will be funded using cash flow from operations and cash set aside for known projects. Other capital expenditures (including acquisitions and plant expansion capital expenditures), should we identify opportunities for such expenditures, may be funded using cash flow from operations or, if significant, will be funded by issuances of debt or equity or cash that has been set aside by the pre-Offering investors. In addition to the capital costs associated with planned major maintenance or expansion projects at our Facility, our production will be reduced during any period in which our Facility is not operating. Our board of directors may elect to reserve amounts in the period(s) preceding such project(s) to fund the estimated capital costs, operating expenses and distributions for the lost margin associated with the loss of production in the period in which the project(s) are expected to occur. The actual costs and lost margin associated with such project(s) may, however, differ from the estimated amounts reserved.

Cash Flows

Operating Activities

Net cash provided by operating activities for the nine months ended September 30, 2012, was $97.1 million. This positive cash flow from operating activities resulted from net income of $8.1 million prior to unrealized losses on the Propane Swaps totaling $90.7 million. Reported net loss also reflects certain non-cash charges for equity-based compensation, depreciation, amortization and accretion, amortization of deferred financing costs, loss on early extinguishment of debt and deferred income taxes totaling $90.4 million. Cash flows from operations was reduced $40.0 million with our posting of cash collateral for the Propane Swaps, which is reported as a current asset, and increased $3.7 million from a net decrease in working capital, excluding the cash collateral. In addition to the decrease in working capital, restricted cash decreased by $34.9 million, adding to operating cash as restrictions on our cash balances were lifted in connection with the refinancing of our prior credit facility.

39

Net cash provided by operating activities for the nine months ended September 30, 2011, was $69.9 million. This positive cash flow from operating activities resulted from net income of $48.9 million, which had been reduced by non-cash charges totaling $75.8 million, which include equity-based compensation expense, depreciation, amortization and accretion expense as well as amortization of deferred financing costs and deferred income tax expense. Cash flow from operating activities was reduced by an increase in restricted cash of $11.3 million combined with an increase in working capital of $43.5 million.

Investing Activities

Net cash used in investing activities for the nine months ended September 30, 2012 and 2011, was $25.6 million and $16.3 million, respectively, related to capital expenditures for our Facility and the purchase of additional air permits for $9.3 million in 2012.

Financing Activities

Net cash used in financing activities for the nine months ended September 30, 2012, was $52.8 million. Our cash flows used in financing activities were primarily due to the full repayment of $145.1 million on our former debt facility, distributions to our Sponsor totaling $250.0 million and cash distributions totaling $20.3 millon. We also received $343.0 million in proceeds from the new term debt, during the nine months ended September 30, 2012. Concurrent with the refinancing, we were able to release a debt service reserve of $10.9 million that had been set aside under the terms of the former credit facility. During the period from the date of the refinancing to September 30, 2012, we borrowed and repaid $ 21.7 million under the new revolving credit facility and repaid principal of $1.8 million on the new term loan facility. We also received proceeds of approximately $24.0 million from the initial public offering.  Additionally, we incurred deferred financing costs of $13.5 million related to the refinancing of our debt and the initial public offering.

Net cash used in financing activities for the nine months ended September 30, 2011, was $53.6 million. Our cash flows used in financing activities were primarily due to the net repayment of $41.9 million on our prior revolving credit facility and term loan during the period as well as the receipt of $2.3 million from our Sponsors for fixed construction capital on our Facility. Also contributing to the negative financing cash flows in 2011 was the establishment of a debt service reserve of $10.9 million and $3.2 million in deferred financing costs.

Off-Balance Sheet Arrangements

We do not have any material “off-balance sheet arrangements” as such term is defined within the rules and regulations of the SEC.

Item 3. quantitative and qualitative disclosures about market risk

Market risk represents the risk of loss that may impact our financial position, results of operations or cash flows due to adverse changes in financial and commodity market prices and rates. Given that our business is currently based entirely in the U.S., we are not directly exposed to foreign currency exchange rate risk.

Commodity Price Risk

Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011, we began entering into the Propane Swaps 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 Propane Swaps, 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 subsequent month, a calculation is performed 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 exceeds the contractual percentage under the Propane Swaps, we are owed a sum by the Propane Swaps counterparty. If the contractual percentage exceeds the actual percentage under the Propane Swaps, we owe a sum to the Propane Swaps counterparty.

41

Upon the closing of the Offering, we entered into the Omnibus Agreement and the Pledge Agreement, pursuant to which the PL Manufacturing Members, through our General Partner, all of our benefits and obligations under the Propane Swaps. Under the Omnibus Agreement and the Pledge Agreement, any amounts received by us under the Propane Swaps will be distributed, through our General Partner, to the PL Manufacturing Members, and any amounts that we are required to pay under the Propane Swaps are expected to be contributed back to us as a capital contribution by the PL Manufacturing Members. While we will not receive any of the benefits of the Propane Swaps, we remain a party to the Propane Swaps, and are obligated to make payments to the Propane Swap counterparties as they come due.

Interest Rate Risk

As required by our new term loan facility, we entered into an interest rate protection agreement in July 2012. Additionally, our management will continue to monitor whether financial derivatives become available which could effectively hedge identified risks. In the future, management may elect to use derivative financial instruments consistent with our overall business objectives to avoid unnecessary risk and to limit, to the extent practical, risks associated with our operating activities.

42

Item 4.  CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We have established disclosure controls and procedures to ensure that material information relating to the Partnership and its consolidated subsidiaries is made known to the officers of our General Partner who certify our financial reports and the Board of Directors.

Our Principal Executive Officers, David Lumpkins and Nathan Ticatch, and our Principal Financial Officer, Sharon Spurlin, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act), as of the end of the quarterly period ended September 30, 2012 (the Evaluation Date). Based on this evaluation, they believe that as of the Evaluation Date our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act (i) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and (ii) is accumulated and communicated to our management, including the Principal Executive Officers and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

There has not been any change in our internal control over financial reporting that occurred during our quarterly period ended September 30, 2012, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. LEGAL PROCEEDINGS.

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.

Item 1A.  RISK FACTORS

In addition to the other information set forth in this Form 10-Q, you should carefully consider the factors discussed under the heading “Risk Factors” in the Prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012, which could materially affect our business, financial condition, or future results. The risks described in the Prospectus are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, or operating results.

Item 2.  UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Issuer Purchases of Equity Securities

We did not repurchase any of our equity securities during the period covered by this report.

Item 3.  DEFAULTS UPON SENIOR SECURITIES

We did not have any defaults on our term loan facility during the period covered by this report.

On May 4, 2012, our common units began trading on the New York Stock Exchange under the symbol “PDH.” On May 9, 2012, we completed our Offering of 35,000,000 common units representing limited partner interests. Pursuant to a Registration Statement on Form S-1, as amended through the date of its effectiveness, we sold 1,500,000 common units, and Propylene Holdings sold 33,500,000 common units at a price to the public of $17 per common unit ($15.98 per common unit, net of underwriting discounts).  Immediately prior to the Offering, the outstanding limited partner interests in the Partnership were recapitalized into 139,000,000 common units pursuant to an amended and restated limited partnership agreement.  We received net proceeds of approximately $24.0 million from the sale of the common units, after deducting underwriting discounts.  For further information related to the Offering, refer to our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.  The underwriters to the Offering did not exercise their rights to purchase additional common units.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

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. The accompanying interim consolidated financial statements do not include all the notes that would be included in our annual financial statements and, therefore, should be read in conjunction with the financial statements and notes thereto included in our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.

Summary of Significant Accounting Policies

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 period. 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 or our Predecessor for any interim period are not necessarily indicative of results for the full year.

Derivative Instruments

Commencing October 2011, 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. Our principal use of the Propane Swaps is to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our Propane Swaps 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 are able and willing to bear it.

In addition to the Propane Swaps, 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 new term loan. The agreement terminates March 27, 2014.

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 enter into our commodity derivative contracts to economically hedge an exposure through a relationship that does not qualify for hedge accounting under ASC Topic 815. Our derivative contracts are recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet, and the associated unrealized gains and losses are recorded as current expense or income in the statement of comprehensive income (loss). 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 on the cash flow statement. Until settlement occurs, this will result 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), the Partnership allocated all of its 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).

Under the Omnibus Agreement and the Pledge Agreement, any amounts received by the Partnership under the Propane Swaps will be distributed to PL Manufacturing and the PL Manufacturing Members, and any amounts that the Partnership is required to pay under the Propane Swaps will be contributed to the Partnership as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

While the Partnership does not receive any of the benefits of the Propane Swaps, it remains a party to the Propane Swaps, and will be obligated to make payments to the Propane Swap counterparties as they come due and to post any collateral as required, under the terms of the Propane Swap agreement. As a result, the Partnership will continue to record the fair value of the Propane Swaps on its balance sheet with the related charge being reflected in its statement of comprehensive income (loss) in accordance with SEC Staff Accounting Bulletin No. 79. To the extent that the Partnership makes payments under the Propane Swaps, PL Manufacturing and the PL Manufacturing Members will be responsible for making quarterly capital contributions in an amount equal to the sum of all payments made by the Partnership under such Propane Swaps during the applicable fiscal quarter or owed by the Partnership at the end of the quarter. During the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members contributed approximately $16 million to the Partnership as reimbursement for realized losses on the Propane Swaps pro-rated from May 9, 2012, the closing date of the Offering, through June 30, 2012. The contribution was made in the form of a reduction in the cash distribution paid to PL Manufacturing and the PL Manufacturing Members. For realized losses on the Propane Swaps in the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members will contribute approximately $31.0 million to the Partnership in November 2012 which is reflected as a related party account receivable at September 30, 2012, in our consolidated balance sheet. The contribution will be partially funded through a reduction in the cash distribution to PL Manufacturing and the PL Manufacturing Members in November 2012 with the remaining portion funded with a cash payment of approximately $9.2 million from PL Manufacturing and the PL Manufacturing Members. In April 2012, we deposited $40.0 million in cash with the Propane Swaps counterparty. The cash is held by the counterparty and is reported as prepaid and other current assets in our consolidated balance sheet.

The Partnership expects that PL Manufacturing and the PL Manufacturing Members will continue to fund their future payment obligations primarily through quarterly distributions that they receive on common units that they own and through the form of additional cash payments should the quarterly distribution not be adequate to cover the amount due on the realized losses from the Propane Swaps. Under the Pledge Agreement, the PL Manufacturing Members pledged to PL Manufacturing (as collateral agent) a number of common units such that, at all times, the market value of all pledged units and all common units owned by PL Manufacturing that are subject to the Omnibus Agreement is equal to or greater than 10 times the mark-to-market value of the Propane Swaps, but in no event shall the number of pledged units be greater than the amount of units distributed to PL Manufacturing and the PL Manufacturing Members in connection with the Offering. The expected aggregate quarterly distributions payable on all pledged common units, together with a cash reserve held by PL Manufacturing, are expected to be sufficient to cover future payments under the Propane Swaps.

Equity-Based Compensation

We recognize compensation expense related to equity-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 7). The grant date fair value of the equity-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.

We also account for equity-based awards granted to non-employees based on the estimated fair value of the awards. The measurement of equity-based compensation for awards granted to non-employees is subject to periodic adjustment as the awards vest, and the resulting change in value is recognized in the statement of comprehensive income (loss) during the period the related services are rendered.

Fair Value of Financial Instruments

We consider cash, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable, 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. The Partnership makes certain assumptions it believes 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. The Partnership believes it uses 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 September 30, 2012.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	2,401	$	—	$	2,401
Financial liabilities
Variable rate debt	$	—	$	345,843	$	—	$	341,925
Propane swaps	—		94,738		—		94,738

The following table presents the financial instruments that require fair value disclosure as of December 31, 2011.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	6,178	$	—	$	6,178
Financial liabilities
Variable rate debt	—		145,115		—		145,115
Propane swaps	—		7,845		—		7,845

The variable rate debt is deemed to be a Level 2 financial instrument because it is based on observable market data. At September 30, 2012, the fair value was determined based on active trades and market corroborated data. To determine the fair value at December 31, 2011, we reviewed the current market interest rates and terms of similar debt, and concluded that the carrying value of the variable rate debt approximates the fair value.

The valuation assumptions utilized to measure the fair value of our Propane Swaps were observable inputs based on market data obtained from independent sources and are considered Level 2 inputs. To determine the fair value of the Propane Swaps, we utilized quoted prices for similar assets, liabilities and market-corroborated inputs.  See Note 5 for discussion regarding our Propane Swaps.

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 nine months ended September 30, 2012.

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 (Loss) Per Common Unit

Net income (loss) 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 (loss) 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 (loss) for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income (loss) be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income (loss) as if all of the net income (loss) for the period had been distributed in accordance with the partnership agreement. Restricted units granted under the PetroLogistics Long-Term Incentive Plan (the Long-Term Incentive Plan) are eligible for Unit Distribution Rights (UDRs). To the extent that non-forfeitable UDRs are awarded, the underlying nonvested restricted units are considered participating securities for purposes of determining net income (loss) per unit.  Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and restricted units 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 restricted units as they do not participate in net losses.  Distributions 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 (loss).  Prior to the Offering, we were wholly-owned by Propylene Holdings.  Accordingly, net income (loss) per common unit is not presented for periods prior to the Offering.

The following table provides a reconciliation of net income (loss) and the allocation of net income to the common units and the restricted units for purposes of computing net income (loss) per unit for the three months ended September 30, 2012, (in thousands, except per unit data):

Recently Issued Accounting Standards

In May 2011, the FASB issued new guidance for fair value measurements intended to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards (IFRS). The amended guidance provides a consistent definition of fair value to ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. The amended guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. We adopted the new fair value measurement guidance on January 1, 2012, and the adoption did not have a material impact on our financial position or results of operations.

                In June 2011, the FASB issued guidance that modified how comprehensive income is presented in an entity’s financial statements. The guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of equity. We adopted the guidance pertaining to the presentation of other comprehensive income as of January 1, 2012, and the adoption did not have an impact on our financial statements or results of operations.

In December 2011, the FASB issued an accounting standards update on disclosures for offsetting assets and liabilities. The new accounting guidance requires companies to disclose both gross and net information about (1) instruments and transactions eligible for offset in the statement of financial position, and (2) instruments and transactions subject to an agreement similar to a master netting arrangement. The accounting standards update will be effective for reporting periods beginning on or after January 1, 2013, and is not expected to have a significant impact on our financial position or results of operations.

Organization and Nature of Operations

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. The information presented in this Quarterly Report on Form 10-Q contains the unaudited combined financial results of PL Propylene LLC (PL Propylene), our predecessor for accounting purposes (the Predecessor), for all periods presented through March 30, 2012. The consolidated financial results for the three and nine months ended September 30, 2012, also include the results of operations of the Partnership for the period beginning March 30, 2012, the date of the contribution of the Predecessor’s net assets to the Partnership. The consolidated balance sheet as of September 30, 2012, presents solely the consolidated financial position of the Partnership. References in this report to our “Sponsors” refer to Lindsay Goldberg LLC (Lindsay Goldberg) and York Capital Management which, after completion of our initial public offering (the Offering), collectively and indirectly own 84% of PetroLogistics GP (our General Partner) and directly and indirectly own 63% of our common units. See Note 3 to these consolidated financial statements for information regarding the Offering.

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 own and operate the only U.S. propane dehydrogenation facility producing propylene from propane.  We developed and built new assets and converted certain existing assets into an “on-purpose” propylene production facility (the Facility) in Houston, Texas, following the purchase of a former olefins manufacturing facility from ExxonMobil Oil Corporation in March 2008. Production at the Facility began on October 21, 2010. 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. The propane dehydrogenation process also produces certain by-products, which we include as sales.

The fair value of our Propane Swap assets decreased from approximately $2.4 million to approximately $1.8 million, and our Propane Swap liabilities decreased from approximately $94.7 million to approximately $65.1 million on October 31, 2012 ($58.0 million current liability and $7.1 million non-current liability), representing an unrealized gain on derivatives of $29.0 million. We also incurred a realized loss on derivatives of approximately $9.6 million in October 2012. Also, see Note 2 regarding the Omnibus Agreement related to our Propane Swaps.

On October 24, 2012, the General Partner approved a distribution to common unitholders of record as of November 5, 2012. The distribution of 21 cents per common unit will be paid on November 14, 2012. PL Manufacturing and the PL Manufacturing Members are required by the Omnibus Agreement to contribute approximately $31.0 million to partially fund their obligation for realized losses on the Propane Swaps through a reduction in the cash distribution payable to them with the remaining portion funded with a cash payment of approximately $9.2 million from PL Manufacturing and the PL Manufacturing Members. We expect to receive payment of the contribution in November 2012, and the entire contribution of $31.0 million is reflected as a related party receivable in our consolidated balance sheet at September 30, 2012.

Prior Credit Facility

We entered into a five-year credit facility agreement in June 2009 that included a $150.0 million construction loan commitment and a $55.0 million revolving credit facility (the prior credit facility). In May 2011 the construction loan was converted to a term loan with principal and interest due quarterly thereafter following the successful completion of a series of tests demonstrating successful operating performance of the Facility as required by the terms of our prior credit facility. In October 2011, the term loan was amended to require monthly principal and quarterly interest payments beginning in January 2012. On March 27, 2012, we refinanced and canceled the prior credit facility with borrowings under a new term loan facility.

New Credit Facilities

On March 27, 2012, PL Propylene, entered into a new term loan facility of $350.0 million and a new revolving credit facility of $120.0 million with Morgan Stanley Senior Funding, Inc. (the Agent), and the lenders party thereto (together, the new credit facilities). We drew $350.0 million under the new term loan facility and used (1) $60.8 million to refinance and cancel our prior credit facilities, (2) $250.0 million to reimburse our Sponsors for construction capital expenditures and (3) approximately $16.5 million to pay associated financing costs and debt discounts. PL Propylene used the remaining amount (approximately $22.7 million) for general partnership purposes. The new term loan included a discount of $7.0 million, which is reported net, less related amortization, against the total outstanding debt in our consolidated balance sheet at September 30, 2012.  The discount is being amortized over the term of the new term loan using the straight-line method, which approximates the effective interest method. We also have the right to add, subject to certain restrictions and conditions, incremental term loan and revolving credit facilities in an amount not to exceed $50.0 million.

The new credit facilities contain certain restrictive financial covenants including limitations on our ability to incur additional debt and the requirement to maintain a Total Secured Leverage Ratio, as defined, no greater than 4.0 to 1.0, but only in the event that on the last day of any quarter beginning with the quarter ended June 30, 2012, the aggregate amounts outstanding under the new revolving credit facility exceed $100.0 million. At September 30, 2012, no amounts were outstanding, and we had $120.0 million available to us under the new revolving credit facility. The new credit facilities are secured by substantially all of PL Propylene’s assets.

Interest Rate and Fees.     Borrowings under the new credit facilities bear interest at a rate per annum based on an underlying base rate plus an applicable margin. The applicable margin for the new term loan facility and the revolving credit facility ranges from 4.75% for loans bearing interest at the Alternate Base Rate to 5.75% for loans bearing interest at LIBOR. At September 30, 2012, the interest rate on the new term loan was based on LIBOR, subject to the LIBOR floor of 1.25%, resulting in a rate of 7%.

The new revolving credit facility also includes a commitment fee calculated at a rate per annum equal to 0.50% on the average daily unused portion of the commitments under the new revolving credit facility.  In addition, we pay an annual management fee for our new term loan facility and our new revolving credit facility. We are 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 5.75%, and 0.125%, respectively.

Amortization and Final Maturity.     The new term loan facility will be amortized in aggregate amounts of 0.25% per fiscal quarter of the original principal amount and will mature on the fifth anniversary of the closing date, March 27, 2017. The new revolving credit facility maturity date is September 27, 2016, at which time the new revolving credit facility will terminate.

In connection with the refinancing, we wrote off approximately $7.0 million of unamortized deferred financing costs associated with the prior credit facility. The write-off of these costs is reflected as a loss on early extinguishment of debt in our consolidated statement of comprehensive income (loss) for the nine month period ended September 30, 2012.

As required by our new 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 new term loan. The agreement terminates March 27, 2014.

Our business activities expose us to risks associated with unfavorable changes in the market price of propylene and propane. Commencing October 2011, 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, a calculation is performed 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 exceeds the contractual percentage under the Propane Swaps, we are owed a sum by the Propane Swaps counterparty. If the contractual percentage exceeds the actual percentage under the Propane Swaps, we owe a sum to the Propane Swaps counterparty. In March 2012, to offset the negative impact of the liability position of our Propane Swaps, we entered into reverse positions for a portion of our Propane Swaps maturing in the second half of 2013. These reverse positions resulted in an asset and are reflected as derivative assets in our consolidated balance sheet at September 30, 2012.

Under the Omnibus Agreement and the Pledge Agreement, any amounts received by the Partnership under the Propane Swaps will be distributed to PL Manufacturing and the PL Manufacturing Members, and any amounts that the Partnership is required to pay under the Propane Swaps will be contributed to the Partnership as a capital contribution by PL Manufacturing and the PL Manufacturing Members. See Note 2 regarding the Omnibus Agreement.

As of September 30, 2012, we had entered into the following outstanding commodity forward contracts to hedge our forecasted energy commodity purchases:

	Volume(1)
	Settlement date
Derivatives not designated as hedging contracts	2012	2013(2)
Propane Swaps, net	1.38 MMBbls	3.83 MMBbls

(1)Volume reflects the absolute value of derivative notional volumes.

(2)The maximum term for derivatives included in the 2013 column is December 2013.

The 2012 and 2013 volumes of 1.38 and 3.83 million barrels (MMBbls) reflect hedged volumes of 15,000 and 11,000 barrels of propane per day, respectively, for each of the years presented with 2013 volumes reduced by a reverse position of 1,000 barrels of propane per day or 0.18 MMBbls for the second half of 2013.

Propane Swaps	$	21,114		$	163,684
Total	$	21,114		$	163,684

There was no activity related to the Propane Swaps in the three or nine months ended September 30, 2011.

Credit Risks

We have counterparty credit risk because the counterparty for all of our derivative contracts is one financial institution. This concentration in one counterparty may impact our overall exposure to credit risk in that the counterparty may be singularly affected by changes in economic, regulatory or other conditions, and our credit risk will not benefit from the benefits of a more diversified group of counterparties.

We maintain credit policies with regard to our counterparty that we believe minimize our overall credit risk. These policies include an evaluation of the counterparty’s financial condition (including credit ratings). Based on our policies and exposure, our management does not anticipate counterparty non-performance and, as a result, no material adverse effect on our financial position, results of operations, or cash flows.

Our derivative contracts are entered into outside of central trading organizations such as futures, options or stock exchanges. These contracts are entered into with a counterparty and, are guaranteed by a parent with an investment grade credit rating. While we enter into derivative transactions with an investment grade counterparty and actively monitor credit ratings, it is nevertheless possible that from time to time losses will result from counterparty credit risk in the future. Our derivative contracts do not permit master netting arrangements at this time.

Basis of Presentation and Summary of Significant Accounting Policies

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 period. 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 or our Predecessor for any interim period are not necessarily indicative of results for the full year.

Derivative Instruments

Derivative Instruments

Commencing October 2011, 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. Our principal use of the Propane Swaps is to mitigate the risk associated with unfavorable market movements in the price of energy commodities. Our Propane Swaps 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 are able and willing to bear it.

In addition to the Propane Swaps, 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 new term loan. The agreement terminates March 27, 2014.

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 enter into our commodity derivative contracts to economically hedge an exposure through a relationship that does not qualify for hedge accounting under ASC Topic 815. Our derivative contracts are recorded as derivative assets and liabilities, as applicable, at fair value on the balance sheet, and the associated unrealized gains and losses are recorded as current expense or income in the statement of comprehensive income (loss). 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 on the cash flow statement. Until settlement occurs, this will result 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), the Partnership allocated all of its 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).

Under the Omnibus Agreement and the Pledge Agreement, any amounts received by the Partnership under the Propane Swaps will be distributed to PL Manufacturing and the PL Manufacturing Members, and any amounts that the Partnership is required to pay under the Propane Swaps will be contributed to the Partnership as a capital contribution by PL Manufacturing and the PL Manufacturing Members.

While the Partnership does not receive any of the benefits of the Propane Swaps, it remains a party to the Propane Swaps, and will be obligated to make payments to the Propane Swap counterparties as they come due and to post any collateral as required, under the terms of the Propane Swap agreement. As a result, the Partnership will continue to record the fair value of the Propane Swaps on its balance sheet with the related charge being reflected in its statement of comprehensive income (loss) in accordance with SEC Staff Accounting Bulletin No. 79. To the extent that the Partnership makes payments under the Propane Swaps, PL Manufacturing and the PL Manufacturing Members will be responsible for making quarterly capital contributions in an amount equal to the sum of all payments made by the Partnership under such Propane Swaps during the applicable fiscal quarter or owed by the Partnership at the end of the quarter. During the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members contributed approximately $16 million to the Partnership as reimbursement for realized losses on the Propane Swaps pro-rated from May 9, 2012, the closing date of the Offering, through June 30, 2012. The contribution was made in the form of a reduction in the cash distribution paid to PL Manufacturing and the PL Manufacturing Members. For realized losses on the Propane Swaps in the quarter ended September 30, 2012, PL Manufacturing and the PL Manufacturing Members will contribute approximately $31.0 million to the Partnership in November 2012 which is reflected as a related party account receivable at September 30, 2012, in our consolidated balance sheet. The contribution will be partially funded through a reduction in the cash distribution to PL Manufacturing and the PL Manufacturing Members in November 2012 with the remaining portion funded with a cash payment of approximately $9.2 million from PL Manufacturing and the PL Manufacturing Members. In April 2012, we deposited $40.0 million in cash with the Propane Swaps counterparty. The cash is held by the counterparty and is reported as prepaid and other current assets in our consolidated balance sheet.

The Partnership expects that PL Manufacturing and the PL Manufacturing Members will continue to fund their future payment obligations primarily through quarterly distributions that they receive on common units that they own and through the form of additional cash payments should the quarterly distribution not be adequate to cover the amount due on the realized losses from the Propane Swaps. Under the Pledge Agreement, the PL Manufacturing Members pledged to PL Manufacturing (as collateral agent) a number of common units such that, at all times, the market value of all pledged units and all common units owned by PL Manufacturing that are subject to the Omnibus Agreement is equal to or greater than 10 times the mark-to-market value of the Propane Swaps, but in no event shall the number of pledged units be greater than the amount of units distributed to PL Manufacturing and the PL Manufacturing Members in connection with the Offering. The expected aggregate quarterly distributions payable on all pledged common units, together with a cash reserve held by PL Manufacturing, are expected to be sufficient to cover future payments under the Propane Swaps.

Equity-Based Compensation

Equity-Based Compensation

We recognize compensation expense related to equity-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 7). The grant date fair value of the equity-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.

We also account for equity-based awards granted to non-employees based on the estimated fair value of the awards. The measurement of equity-based compensation for awards granted to non-employees is subject to periodic adjustment as the awards vest, and the resulting change in value is recognized in the statement of comprehensive income (loss) during the period the related services are rendered.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

We consider cash, accounts receivable, accounts payable, accounts receivable-related parties, accounts payable, 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. The Partnership makes certain assumptions it believes 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. The Partnership believes it uses 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 September 30, 2012.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	2,401	$	—	$	2,401
Financial liabilities
Variable rate debt	$	—	$	345,843	$	—	$	341,925
Propane swaps	—		94,738		—		94,738

The following table presents the financial instruments that require fair value disclosure as of December 31, 2011.

	Fair Value
	(in thousands)
	Level 1		Level 2		Level 3		Carrying Value
Financial assets
Propane swaps	$	—	$	6,178	$	—	$	6,178
Financial liabilities
Variable rate debt	—		145,115		—		145,115
Propane swaps	—		7,845		—		7,845

The variable rate debt is deemed to be a Level 2 financial instrument because it is based on observable market data. At September 30, 2012, the fair value was determined based on active trades and market corroborated data. To determine the fair value at December 31, 2011, we reviewed the current market interest rates and terms of similar debt, and concluded that the carrying value of the variable rate debt approximates the fair value.

The valuation assumptions utilized to measure the fair value of our Propane Swaps were observable inputs based on market data obtained from independent sources and are considered Level 2 inputs. To determine the fair value of the Propane Swaps, we utilized quoted prices for similar assets, liabilities and market-corroborated inputs.  See Note 5 for discussion regarding our Propane Swaps.

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 nine months ended September 30, 2012.

Segment Reporting

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 (Loss) Per Common Unit

Net Income (Loss) Per Common Unit

Net income (loss) 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 (loss) 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 (loss) for a period be reduced by the amount of distributions and that any residual amount representing undistributed net income (loss) be allocated to common unitholders and other participating unitholders to the extent that each unit may share in net income (loss) as if all of the net income (loss) for the period had been distributed in accordance with the partnership agreement. Restricted units granted under the PetroLogistics Long-Term Incentive Plan (the Long-Term Incentive Plan) are eligible for Unit Distribution Rights (UDRs). To the extent that non-forfeitable UDRs are awarded, the underlying nonvested restricted units are considered participating securities for purposes of determining net income (loss) per unit.  Undistributed income is allocated to participating securities based on the proportional relationship of the weighted average number of common units and restricted units 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 restricted units as they do not participate in net losses.  Distributions 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 (loss).  Prior to the Offering, we were wholly-owned by Propylene Holdings.  Accordingly, net income (loss) per common unit is not presented for periods prior to the Offering.

The following table provides a reconciliation of net income (loss) and the allocation of net income to the common units and the restricted units for purposes of computing net income (loss) per unit for the three months ended September 30, 2012, (in thousands, except per unit data):

Recently Issued Accounting Standards

Recently Issued Accounting Standards

In May 2011, the FASB issued new guidance for fair value measurements intended to achieve common fair value measurement and disclosure requirements between U.S. GAAP and International Financial Reporting Standards (IFRS). The amended guidance provides a consistent definition of fair value to ensure that the fair value measurement and disclosure requirements are similar between U.S. GAAP and IFRS. The amended guidance changes certain fair value measurement principles and enhances the disclosure requirements, particularly for Level 3 fair value measurements. We adopted the new fair value measurement guidance on January 1, 2012, and the adoption did not have a material impact on our financial position or results of operations.

                In June 2011, the FASB issued guidance that modified how comprehensive income is presented in an entity’s financial statements. The guidance requires an entity to present the total of comprehensive income, the components of net income, and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements and eliminates the option to present the components of other comprehensive income as part of the statement of equity. We adopted the guidance pertaining to the presentation of other comprehensive income as of January 1, 2012, and the adoption did not have an impact on our financial statements or results of operations.

In December 2011, the FASB issued an accounting standards update on disclosures for offsetting assets and liabilities. The new accounting guidance requires companies to disclose both gross and net information about (1) instruments and transactions eligible for offset in the statement of financial position, and (2) instruments and transactions subject to an agreement similar to a master netting arrangement. The accounting standards update will be effective for reporting periods beginning on or after January 1, 2013, and is not expected to have a significant impact on our financial position or results of operations.

Services Agreement with PetroLogistics GP LLC

We entered into a services agreement with our General Partner on January 1, 2012, pursuant to which our General Partner provides certain operational, managerial and general administrative services to us.  All employees of PL Propylene and PetroLogistics LLC became employees of our General Partner on January 1, 2012.  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.  The amounts we pay the General Partner for these services are reported in the statements of comprehensive income (loss) in the line item to which the expense relates.

First Amended and Restated Agreement of Limited Partnership of PetroLogistics LP

On May 3, 2012, in connection with the completion of the Offering, our General Partner amended and restated our partnership agreement and executed the First Amended and Restated Agreement of Limited Partnership of PetroLogistics LP (the Partnership Agreement), which governs the rights of our partners. Among others, revisions included the recapitalization of our common units in connection with the Offering and provisions regarding allocations and distributions. The full text of the Partnership Agreement can be found in our prospectus dated May 3, 2012, as filed with the SEC on May 7, 2012.

Indemnification Agreement

The Partnership Agreement provides that each of our directors and officers may receive indemnification for actions associated with being a director or officer in order to enhance the indemnification rights provided under Delaware law and the Partnership Agreement. The Partnership Agreement provides each such director or officer with rights to receive his or her costs of defense if the individual is a party or witness to any proceeding other than a proceeding brought by or in the right of, us, provided that such director or officer has not acted in bad faith or engaged in fraud with respect to the action that gave rise to his or her participation in the proceeding.

Other

During the nine months ended September 30, 2012 and 2011, we utilized the services of a company owned by Lindsay Goldberg in the amounts of approximately $1,115,000 and $1,972,000, respectively, in connection with Facility maintenance activities.

In 2011, we entered into an agreement with Lindsay Goldberg, under which we were to pay an annual fee of $2,000,000 for advisory services. This agreement terminated under its terms with the Offering. At the closing of the Offering, we owed Lindsay Goldberg approximately $2,667,000 related to this fee. This amount was waived by Lindsay Goldberg in May 2012 in connection with the Offering, and the accounts payable-related party was reversed at that time with a corresponding increase in partners’ capital.

PL Manufacturing Profits Interest Plan

PL Manufacturing Profits Interest Plan

PL Manufacturing Profits Interest Plan

7. PL Manufacturing Profits Interest Plan

Prior to the Offering, PL Manufacturing maintained a profits interest plan (the Profits Interest Plan) for the benefit of our employees, as well as the key management employees of certain affiliated companies (collectively, Management). Because the Profits Interest Plan was intended to compensate Management with respect to the services they performed for our benefit, the equity-based compensation expense is reflected in our financial statements.

PetroLogistics Company LLC (PetroLogistics LLC) is an entity owned by David Lumpkins and Nathan Ticatch. Through December 31, 2011, the senior executives who oversee our operations were employed by PetroLogistics LLC and provided management services to us pursuant to our services agreement with PetroLogistics LLC. The majority of the profits interests (Profits Interest Units) that PL Manufacturing issued were to persons employed by PetroLogistics LLC. For accounting purposes, we treated these awards as being made to non-employees through December 31, 2011. As of January 1, 2012, all PetroLogistics Company LLC employees transferred their employment to the General Partner. As of that date, the underlying grant date fair value of nonvested Profits Interest Units held by the former PetroLogistics LLC employees became fixed due to the change in employment status, and equity-based compensation expense attributed to these Profits Interest Units for the nine months ended September 30, 2012, was based on the underlying fair value of the Profits Interest Units as of January 1, 2012.

Vesting and Unit Rights

Under the Profits Interest Plan, Class B, C and D Profits Interest Units were granted to management and employees.  The Class B Profits Interest Units were fully vested at the date of issuance, July 23, 2008. The issued and outstanding Class C and Class D Profits Interest Units vested over four years beginning on the later of March 11, 2009, or the recipient’s date of employment. The Class C and Class D Profits Interest Units became fully vested upon the closing of the Offering in May 2012.  There were no forfeitures for any of the periods presented. At the closing of the Offering, remaining unrecognized compensation expense related to the previously nonvested Profits Interest Units was recognized in the amount of approximately $43,710,000.

Determination of Equity-Based Compensation Expense

Equity-based compensation expense for all equity-based awards issued to employees was based on the estimated grant-date fair value of the Profits Interest Units. We recognized this equity-based compensation expense on a straight-line basis over the requisite service period of the award for those Profits Interest Units that were expected to vest. For Profits Interest Units granted to non-employees, non-vested Profits Interest Units were revalued at the reporting date fair value, with any change in value reflected in the statements of comprehensive income (loss).

Total recognized equity-based compensation expense related to the Profits Interest Plan was as follows (in thousands):

Long-Term Incentive Plan

9 Months Ended

Sep. 30, 2012

Long-Term Incentive Plan

Long-Term Incentive Plan

8. Long-Term Incentive Plan

2012 Long-Term Incentive Plan

The Long-Term Incentive Plan has been adopted by our General Partner. 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.

Restricted Unit Awards

A restricted unit award under the Long-Term Incentive Plan is a common unit that vests over a period of time and during that time is subject to forfeiture. Our General Partner anticipates that the majority of our restricted units will generally vest annually over a three-year period from the date of grant provided the recipient has continuously provided services to us, our General Partner, or any other of our affiliates.

Certain restricted unit awards are eligible for UDRs. Absent any restrictions on the UDRs in an award agreement, we will pay UDRs to the holder of the restricted unit without restriction at the same time as we pay quarterly cash distributions to our common unitholders. To the extent provided by the Long-Term Incentive Plan’s Administrative Committee (the Committee), in its discretion, a grant of restricted units may provide that distributions made with respect to the restricted units shall be subject to the same forfeiture and other restrictions as the underlying restricted unit and, if restricted, such distributions shall be held, without interest, until the restricted unit vests or is forfeited with the UDR being paid or forfeited at the same time, as the case may be. In addition, the Committee may provide that such distributions be used to acquire additional restricted units for the participant. Such additional restricted units may be subject to such vesting and other terms as the Committee may prescribe.

During the three months ended September 30, 2012, we recognized total equity-based compensation expense of approximately $777,000 related to the restricted unit awards ($507,000 as cost of sales and $270,000 as general and administrative expense).

Concentration of Risk

Concentration of Risk

10. 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				Nine Months
	Ended				Ended
	September 30,				September 30,
	2012		2011		2012		2011
Dow Chemical Company (Dow)	36	%	60	%	42	%	54	%
Total Petrochemicals USA, Inc. (Total)	20	%	18	%	20	%	24	%
INEOS Olefins and Polymers USA (INEOS)	22	%	15	%	18	%	16	%
LyondellBasell Industries N.V. (LyondellBasell)	14	%	0	%	11	%	1	%
Others (less than 10% individually)	8	%	7	%	9	%	5	%
Total sales	100	%	100	%	100	%	100	%

We have entered into market-based sales contracts with our propylene customers to provide minimum annual quantities. (see Note 11). These minimum quantities comprise the substantial majority of the 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 are unable to meet our production requirements if we are unable to locate and procure replacement volumes from alternate sources.

Counterparty Risk with Respect to Derivative Instruments

Our business activities expose us to the risk associated with changes in the market price of propylene and propane. In order to manage our exposure to the price risk related to propane, we began entering into derivative contracts in October 2011. The derivative contracts permit us to economically hedge a portion of our expected propane needs for 2012 and 2013 (see Note 5).

In those situations where we are exposed to credit risk in our derivative instruments transactions, we analyze the counterparty’s financial condition prior to entering into an agreement. Generally, we do not require collateral nor do we anticipate nonperformance by our counterparty.
