Partnership Organization

Partnership Organization	6 Months Ended
	Mar. 31, 2016
Partnership Organization	1) Partnership Organization Star Gas Partners, L.P. (“Star Gas Partners,” the “Partnership,” “we,” “us,” or “our”) is a full service provider specializing in the sale of home heating products and services to residential and commercial customers. The Partnership also services and sells heating and air conditioning equipment to its home heating oil and propane customers and to a lesser extent, provides these offerings to customers outside of our home heating oil and propane customer base. In certain of our marketing areas, we provide home security and plumbing services primarily to our home heating oil and propane customer base. We also sell diesel fuel, gasoline and home heating oil on a delivery only basis. These products and services are offered through our home heating oil and propane locations. The Partnership has one reportable segment for accounting purposes. We are the nation’s largest retail distributor of home heating oil based upon sales volume. Including our propane locations, we serve customers in the more northern and eastern states within the Northeast, Central and Southeast U.S. regions. The Partnership is organized as follows: • The Partnership is a master limited partnership, which as of March 31, 2016, had outstanding 57.2 million Common Units (NYSE: “SGU”), representing 99.43% limited partner interest in Star Gas Partners, and 0.3 million general partner units, representing 0.57% general partner interest in Star Gas Partners. The general partner of the Partnership is Kestrel Heat, LLC, a Delaware limited liability company (“Kestrel Heat” or the “general partner”). The Board of Directors of Kestrel Heat (the “Board”) is appointed by its sole member, Kestrel Energy Partners, LLC, a Delaware limited liability company (“Kestrel”). • The Partnership owns 100% of Star Acquisitions, Inc., a Minnesota corporation (“SA”), that owns 100% of Petro Holdings, Inc., a Minnesota corporation (“Petro”). SA and its subsidiaries are subject to Federal and state corporate income taxes. The Partnership’s operations are conducted through Petro and its subsidiaries. Petro is primarily a Northeast, Central and Southeast region retail distributor of home heating oil and propane that as of March 31, 2016, served approximately 452,000 full-service residential and commercial home heating oil and propane customers. Petro also sold diesel fuel, gasoline and home heating oil to approximately 79,000 customers on a delivery only basis. In addition, Petro installed, maintained, and repaired heating and air conditioning equipment for its customers and provided ancillary home services, including home security and plumbing, to approximately 26,000 customers. • Petroleum Heat and Power Co., Inc., a Minnesota corporation (“PH&P”) is a 100% owned subsidiary of the Partnership. PH&P is the borrower and the Partnership is the guarantor of the third amended and restated credit agreement’s five-year senior secured term loan and the $300 million ($450 million during the heating season of December through April of each year) revolving credit facility, both due July 30, 2020 (See Note 9—Long-Term Debt and Bank Facility Borrowings).

Summary of Significant Accounti

Summary of Significant Accounting Policies	6 Months Ended

Summary of Significant Accounting Policies	2) Summary of Significant Accounting Policies Basis of Presentation The Consolidated Financial Statements include the accounts of Star Gas Partners and its subsidiaries. All material inter-company items and transactions have been eliminated in consolidation. The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Partnership’s business, the results of operations and cash flows for the six month period ended March 31, 2016, and March 31, 2015, are not necessarily indicative of the results to be expected for the full year. These interim financial statements of the Partnership have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission and should be read in conjunction with the financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended September 30, 2015. Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of the unrealized gain (loss) amortization on the Partnership’s pension plan obligation for its two frozen defined benefit pension plans and the corresponding tax effect. Weather Hedge Contract To partially mitigate the adverse effect of warm weather on cash flows, the Partnership has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives. The premium paid is included in the caption Prepaid Expenses and Other Current Assets in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period. For fiscal years 2016 and 2017 the Partnership has a weather hedge contract with Swiss Re under which the Partnership is entitled to receive a payment of $35,000 per heating degree-day shortfall, when the accumulated number of heating degree-days in the entire hedge period is less than approximately 92.5% of the ten year average, the Payment Threshold as defined in the contract. The hedge covers the five month period from November 1, through March 31, taken as a whole, and has a maximum payout of $12.5 million for each respective fiscal year. The amount due to the Partnership at March 31, 2016 is $12.5 million based on the degree-day shortfall experienced during the most recent five month hedge period. In April 2016, the Partnership received $12.5 million from Swiss Re. New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability As of March 31, 2016 we had $0.1 million and $17.6 million included in the captions Accrued Expenses and Other Current Liabilities and Other Long-Term Liabilities, respectively, on our condensed consolidated balance sheet representing the remaining balance of the NETTI withdrawal liability. Based on the borrowing rates currently available to the Partnership for long-term financing of a similar maturity, the fair value of the NETTI withdrawal liability as of March 31, 2016 was $17.1 million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace the latest revenue recognition guidance in GAAP when it becomes effective. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2019, with early adoption permitted beginning in the first quarter of fiscal 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Partnership is evaluating the effect that ASU No. 2014-09 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. The update requires retrospective application and represents a change in accounting principle. The update is effective for our annual reporting period beginning in the first quarter of fiscal 2017, with early adoption permitted. The impact of ASU No. 2015-03 will be limited to the presentation of debt issuance cost on our balance sheet. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. The update changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2018, with early adoption permitted. The Partnership does not expect ASU No. 2015-11 to have a material impact on its consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which requires an acquiring entity to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquiring entity is required to record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, the acquiring entity is to present separately on the face of its income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods as if the adjustment to the provisional amounts had been recognized as of the acquisition date. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2017. The Partnership does not expect ASU No. 2015-16 to have a material impact on its consolidated financial statements and related disclosures. In November 2015, FASB issued ASU No. 2015-17, Income Taxes - Balance Sheet Classification of Deferred Taxes, which eliminates the requirement for companies to present deferred tax assets and liabilities as current and non-current in a classified balance sheet. Instead, companies will be required to classify all deferred tax assets and liabilities as non-current. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2018, with early adoption permitted. The standard permits the use of either the prospective or retrospective transition method. The Partnership is evaluating the effect that ASU No. 2015-17 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption. In February 2016, the FASB issued ASU No. 2016-02, Leases. The update requires all leases with a term greater than twelve months to be recognized on the balance sheet through a right-of-use asset and a lease liability, and the disclosure of key information pertaining to leasing arrangements. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2020, with early adoption permitted. The Partnership is evaluating the effect that ASU No. 2016-02 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption.

Common Unit Repurchase and Reti

Common Unit Repurchase and Retirement	6 Months Ended

Common Unit Repurchase and Retirement	3) Common Unit Repurchase and Retirement In July 2012, the Board authorized the repurchase of up to 3.0 million of the Partnership’s Common Units (“Plan III”). In July 2013, the Board authorized the repurchase of an additional 1.9 million Common Units under Plan III. The authorized Common Unit repurchases may be made from time to time in the open market, in privately negotiated transactions or in such other manner deemed appropriate by management. There is no guarantee of the exact number of units that will be purchased under the program and the Partnership may discontinue purchases at any time. The program does not have a time limit. The Board may also approve additional purchases of units from time to time in private transactions. The Partnership’s repurchase activities take into account SEC safe harbor rules and guidance for issuer repurchases. All of the Common Units purchased in the repurchase program will be retired. Under the Partnership’s third amended and restated credit agreement dated July 30, 2015, in order to repurchase Common Units we must maintain Availability (as defined in the amended and restated credit agreement) of $45 million, 15.0% of the facility size of $300 million (assuming the non-seasonal aggregate commitment is in effect) on a historical pro forma and forward-looking basis, and a fixed charge coverage ratio of not less than 1.15 measured as of the date of repurchase. The Partnership was in compliance with this covenant for all unit repurchases made during the six months ended March 31, 2016. The following table shows repurchases under Plan III.

Derivatives and Hedging-Disclosures and Fair Value Measurements	4) Derivatives and Hedging—Disclosures and Fair Value Measurements FASB ASC 815-10-05 Derivatives and Hedging, established accounting and reporting standards requiring that derivative instruments be recorded at fair value and included in the consolidated balance sheet as assets or liabilities, along with qualitative disclosures regarding the derivative activity. The Partnership uses derivative instruments such as futures, options and swap agreements in order to mitigate exposure to market risk associated with the purchase of home heating oil for price-protected customers, physical inventory on hand, inventory in transit, priced purchase commitments and internal fuel usage. The Partnership has elected not to designate its derivative instruments as hedging derivatives, but rather as economic hedges whose change in fair value is recognized in its statement of operations in the line item (increase) decrease in the fair value of derivative instruments. Depending on the risk being economically hedged, realized gains and losses are recorded in cost of product, cost of installations and services, or delivery and branch expenses. As of March 31, 2016, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Partnership held the following derivative instruments that settle in future months to match anticipated sales: 5.4 million gallons of swap contracts, 3.4 million gallons of call options, 3.5 million gallons of put options, and 58.7 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Partnership, as of March 31, 2016, had 0.7 million gallons of long swap contracts, 34.0 million gallons of long future contracts, and 53.1 million gallons of short future contracts that settle in future months. In addition to the previously described hedging instruments, to lock-in the differential between high sulfur home heating oil and ultra low sulfur diesel, the Partnership as of March 31, 2016, had 2.1 million gallons of spread contracts (simultaneous long and short positions). To hedge its internal fuel usage and other related activities for fiscal 2016, the Partnership, as of March 31, 2016, had 4.6 million gallons of swap contracts that settle in future months. As of March 31, 2015, to hedge a substantial majority of the purchase price associated with heating oil gallons anticipated to be sold to its price-protected customers, the Partnership held the following derivative instruments that settle in future months to match anticipated sales: 6.3 million gallons of swap contracts, 4.1 million gallons of call options, 3.1 million gallons of put options, and 54.7 million net gallons of synthetic call options. To hedge the inter-month differentials for its price-protected customers, its physical inventory on hand and inventory in transit, the Partnership, as of March 31, 2015, had 34.1 million gallons of long future contracts, and 54.7 million gallons of short future contracts that settle in future months. To hedge its internal fuel usage and other related activities for fiscal 2015, the Partnership, as of March 31, 2015, had 3.2 million gallons of swap contracts that settle in future months. The Partnership’s derivative instruments are with the following counterparties: Bank of America, N.A., Bank of Montreal, Cargill, Inc., Citibank, N.A., JPMorgan Chase Bank, N.A., Key Bank, N.A., Munich Re Trading LLC, Regions Financial Corporation, Societe Generale, and Wells Fargo Bank, N.A. The Partnership assesses counterparty credit risk and considers it to be low. We maintain master netting arrangements that allow for the non-conditional offsetting of amounts receivable and payable with counterparties to help manage our risks and record derivative positions on a net basis. The Partnership generally does not receive cash collateral from its counterparties and does not restrict the use of cash collateral it maintains at counterparties. At March 31, 2016, the aggregate cash posted as collateral in the normal course of business at counterparties was $3.4 million ($3.4 million recorded in prepaid expenses and other current assets). Positions with counterparties who are also parties to our credit agreement are collateralized under that facility. As of March 31, 2016, $7.9 million of hedge positions and payable amounts were secured under the credit facility. FASB ASC 820-10 Fair Value Measurements and Disclosures, established a three-tier fair value hierarchy, which classified the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. The Partnership’s Level 1 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are identical and traded in active markets. The Partnership’s Level 2 derivative assets and liabilities represent the fair value of commodity contracts used in its hedging activities that are valued using either directly or indirectly observable inputs, whose nature, risk and class are similar. No significant transfers of assets or liabilities have been made into and out of the Level 1 or Level 2 tiers. All derivative instruments were non-trading positions and were either a Level 1 or Level 2 instrument. The Partnership had no Level 3 derivative instruments. The fair market value of our Level 1 and Level 2 derivative assets and liabilities are calculated by our counter-parties and are independently validated by the Partnership. The Partnership’s calculations are, for Level 1 derivative assets and liabilities, based on the published New York Mercantile Exchange (“NYMEX”) market prices for the commodity contracts open at the end of the period. For Level 2 derivative assets and liabilities the calculations performed by the Partnership are based on a combination of the NYMEX published market prices and other inputs, including such factors as present value, volatility and duration.

On July 30, 2015, the Partnership entered into a third amended and restated asset based credit agreement with a bank syndicate comprised of thirteen participants, which enables the Partnership to borrow up to $300 million ($450 million during the heating season of December through April of each year) on a revolving credit facility for working capital purposes (subject to certain borrowing base limitations and coverage ratios), provides for a $100 million five-year senior secured term loan (the “$100 million Term Loan”), allows for the issuance of up to $100 million in letters of credit, and has a maturity date of July 30, 2020. The Partnership can increase the revolving credit facility size by $100 million without the consent of the bank group. However, the bank group is not obligated to fund the $100 million increase. If the bank group elects not to fund the increase, the Partnership can add additional lenders to the group, with the consent of the Agent, which shall not be unreasonably withheld. Obligations under the third amended and restated credit facility are guaranteed by the Partnership and its subsidiaries and are secured by liens on substantially all of the Partnership’s assets including accounts receivable, inventory, general intangibles, real property, fixtures and equipment. All amounts outstanding under the third amended and restated revolving credit facility become due and payable on the facility termination date of July 30, 2020. The $100 million Term Loan, whose balance at March 31, 2016, was $97.5 million, is repayable in quarterly payments of $2.5 million, plus an annual payment equal to 25% of the annual Excess Cash Flow as defined in the agreement (an amount not to exceed $15 million annually), less certain voluntary prepayments made during the year, with final payment at maturity. The interest rate on the third amended and restated revolving credit facility and the term loan is based on a margin over LIBOR or a base rate. At March 31, 2016, the effective interest rate on the term loan was approximately 3.58%. The Commitment Fee on the unused portion of the revolving credit facility is 0.30% from December through April, and 0.20% from May through November. The third amended and restated credit agreement requires the Partnership to meet certain financial covenants, including a fixed charge coverage ratio (as defined in the credit agreement) of not less than 1.1 as long as the $100 million Term Loan is outstanding or revolving credit facility availability is less than 12.5% of the facility size. In addition, as long as the $100 million Term Loan is outstanding, a senior secured leverage ratio at any time cannot be more than 3.0 as calculated during the quarters ending June or September, and at any time no more than 4.5 as calculated during the quarters ending December or March. Certain restrictions are also imposed by the agreement, including restrictions on the Partnership’s ability to incur additional indebtedness, to pay distributions to unitholders, to pay certain inter-company dividends or distributions, make investments, grant liens, sell assets, make acquisitions and engage in certain other activities. At March 31, 2016, $97.5 million of the term loan was outstanding, no amount was outstanding under the revolving credit facility, $7.9 million of hedge positions were secured under the credit agreement, and $49.6 million of letters of credit were issued and outstanding. At September 30, 2015, $100.0 million of the term loan was outstanding, no amount was outstanding under the revolving credit facility, $15.3 million of hedge positions were secured under the credit agreement, and $54.8 million of letters of credit were issued and outstanding. At March 31, 2016, availability was $242.5 million, and the Partnership was in compliance with the fixed charge coverage ratio and the senior secured leverage ratio. At September 30, 2015, availability was $176.0 million, and the Partnership was in compliance with the fixed charge coverage ratio and the senior secured leverage ratio.

Income Taxes

Income Taxes	6 Months Ended
	Mar. 31, 2016
Income Taxes	10) Income Taxes Since Star Gas Partners is organized as a master limited partnership, it is not subject to tax at its entity level for Federal and state income tax purposes. However, Star Gas Partners’ income is derived from its corporate subsidiaries, and these entities do incur Federal and state income taxes relating to their respective corporate subsidiaries, which are reflected in these financial statements. For the corporate subsidiaries of Star Gas Partners, a consolidated Federal income tax return is filed. Income and losses of Star Gas Partners are allocated directly to the individual partners. Even though Star Gas Partners will generate non-qualifying Master Limited Partnership income through its corporate subsidiaries, cash received by Star Gas Partners from its corporate subsidiaries is generally included in the determination of qualified Master Limited Partnership income. All or a portion of such cash could be taxable as dividend income or as a capital gain to the individual partners. This could be the case even if Star Gas Partners used the cash received from its corporate subsidiaries for purposes such as the repurchase of Common Units, other types of capital transactions, or paying its own expenses rather than for distributions to its individual partners. The Bipartisan Budget Act of 2015 provides that any tax adjustments resulting from partnership audits will generally be determined, and any resulting tax, interest and penalties collected, at the partnership level for tax years beginning after December 31, 2017. The accompanying financial statements are reported on a fiscal year, however, Star Gas Partners and its corporate subsidiaries file Federal and state income tax returns on a calendar year. The current and deferred income tax expenses for the three and six months ended March 31, 2016, and 2015 are as follows: Three Months Ended Six Months Ended March 31, March 31, (in thousands) 2016 2015 2016 2015 Income before income taxes $ 94,113 $ 129,876 $ 115,588 $ 156,789 Current tax expense $ 31,218 $ 46,642 $ 40,027 $ 57,772 Deferred tax expense 7,686 7,547 8,294 7,776 Total tax expense $ 38,904 $ 54,189 $ 48,321 $ 65,548 As of January 1, 2016, Star Acquisitions, Inc., a wholly-owned subsidiary of the Partnership, had an estimated Federal net operating loss carry forward (“NOLs”) of approximately $3.9 million. The Federal NOLs, which will expire between 2018 and 2024, are generally available to offset any future taxable income but are also subject to annual limitations of between $1.0 million and $2.2 million. Due to a change in a state tax law enacted in December 2015, the Partnership increased its valuation allowance by $0.5 million. The balance of the valuation allowance at March 31, 2016, is $3.5 million. At March 31, 2016, we did not have unrecognized income tax benefits. Our continuing practice is to recognize interest and penalties related to income tax matters as a component of income tax expense. We file U.S. Federal income tax returns and various state and local returns. A number of years may elapse before an uncertain tax position is audited and finally resolved. For our Federal income tax returns we have four tax years subject to examination. In our major state tax jurisdictions of New York, Connecticut, Pennsylvania and New Jersey, we have four, four, four, and five tax years, respectively, that are subject to examination. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, based on our assessment of many factors including past experience and interpretation of tax law, we believe that our provision for income taxes reflect the most probable outcome. This assessment relies on estimates and assumptions and may involve a series of complex judgments about future events.

Commitments and Contingencies	12) Commitments and Contingencies On February 18, 2016, a civil action was filed in the United States District Court, District of New Jersey, entitled M. Norman Donnenfeld v. Petro Home Services, Petro Holdings Inc. and Petro, Inc., The Partnership’s operations are subject to the operating hazards and risks normally incidental to handling, storing and transporting and otherwise providing for use by consumers hazardous liquids such as home heating oil and propane. The Partnership maintains insurance policies with insurers in amounts and with coverages and deductibles we believe are reasonable and prudent. However, the Partnership cannot assure that this insurance will be adequate to protect it from all material expenses related to potential future claims. In the ordinary course of business the Partnership is a defendant in various legal proceedings and litigations. The Partnership records a liability when it is probable that a loss has been incurred and the amount is reasonably estimable. We do not believe these matters when considered individually or in the aggregate, could reasonably be expected to have a material adverse effect on the Partnership’s results of operations, financial position or liquidity.

Earnings Per Limited Partner Un

Earnings Per Limited Partner Unit	6 Months Ended
	Mar. 31, 2016
Earnings Per Limited Partner Unit	13) Earnings Per Limited Partner Unit Income per limited partner unit is computed in accordance with FASB ASC 260-10-05 Earnings Per Share, Master Limited Partnerships (EITF 03-06), by dividing the limited partners’ interest in net income by the weighted average number of limited partner units outstanding. The pro forma nature of the allocation required by this standard provides that in any accounting period where the Partnership’s aggregate net income exceeds its aggregate distribution for such period, the Partnership is required to present net income per limited partner unit as if all of the earnings for the periods were distributed, regardless of whether those earnings would actually be distributed during a particular period from an economic or practical perspective. This allocation does not impact the Partnership’s overall net income or other financial results. However, for periods in which the Partnership’s aggregate net income exceeds its aggregate distributions for such period, it will have the impact of reducing the earnings per limited partner unit, as the calculation according to this standard result in a theoretical increased allocation of undistributed earnings to the general partner. In accounting periods where aggregate net income does not exceed aggregate distributions for such period, this standard does not have any impact on the Partnership’s net income per limited partner unit calculation. A separate and independent calculation for each quarter and year-to-date period is performed, in which the Partnership’s contractual participation rights are taken into account. The following presents the net income allocation and per unit data using this method for the periods presented: Three Months Ended Six Months Ended Basic and Diluted Earnings Per Limited Partner: March 31, March 31, (in thousands, except per unit data) 2016 2015 2016 2015 Net income $ 55,209 $ 75,687 $ 67,267 $ 91,241 Less General Partner’s interest in net income 313 428 381 516 Net income available to limited partners 54,896 75,259 66,886 90,725 Less dilutive impact of theoretical distribution of earnings under FASB ASC 260-10-45-60 9,617 13,616 10,960 15,705 Limited Partner’s interest in net income under FASB ASC 260-10-45-60 $ 45,279 $ 61,643 $ 55,926 $ 75,020 Per unit data: Basic and diluted net income available to limited partners $ 0.96 $ 1.31 $ 1.17 $ 1.58 Less dilutive impact of theoretical distribution of earnings under FASB ASC 260-10-45-60 0.17 0.23 0.19 0.27 Limited Partner’s interest in net income under FASB ASC 260-10-45-60 $ 0.79 $ 1.08 $ 0.98 $ 1.31 Weighted average number of Limited Partner units outstanding 57,242 57,282 57,262 57,288

Subsequent Events	14) Subsequent Events Quarterly Distribution Declared In April 2016, we declared a quarterly distribution of $0.1025 per unit, or $0.41 per unit on an annualized basis, on all Common Units with respect to the second quarter of fiscal 2016, payable on May 6, 2016, to holders of record on April 28, 2016. In accordance with our Partnership Agreement, the amount of distributions in excess of the minimum quarterly distribution of $0.0675, are distributed 90% to Common Unit holders and 10% to the General Partner unit holders (until certain distribution levels are met), subject to the management incentive compensation plan. As a result, $5.9 million will be paid to the Common Unit holders, $0.13 million to the General Partner unit holders (including $0.1 million of incentive distribution as provided in our Partnership Agreement) and $0.1 million to management pursuant to the management incentive compensation plan which provides for certain members of management to receive incentive distributions that would otherwise be payable to the General Partner.

Basis of Presentation	Basis of Presentation The Consolidated Financial Statements include the accounts of Star Gas Partners and its subsidiaries. All material inter-company items and transactions have been eliminated in consolidation. The financial information included herein is unaudited; however, such information reflects all adjustments (consisting solely of normal recurring adjustments), which are, in the opinion of management, necessary for the fair statement of financial condition and results for the interim periods. Due to the seasonal nature of the Partnership’s business, the results of operations and cash flows for the six month period ended March 31, 2016, and March 31, 2015, are not necessarily indicative of the results to be expected for the full year. These interim financial statements of the Partnership have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”) for interim financial information and Rule 10-01 of Regulation S-X of the U.S. Securities and Exchange Commission and should be read in conjunction with the financial statements included in the Partnership’s Annual Report on Form 10-K for the year ended September 30, 2015.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) is comprised of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) consists of the unrealized gain (loss) amortization on the Partnership’s pension plan obligation for its two frozen defined benefit pension plans and the corresponding tax effect.
Weather Hedge Contract	Weather Hedge Contract To partially mitigate the adverse effect of warm weather on cash flows, the Partnership has used weather hedge contracts for a number of years. Weather hedge contracts are recorded in accordance with the intrinsic value method defined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 815-45-15 Derivatives and Hedging, Weather Derivatives. The premium paid is included in the caption Prepaid Expenses and Other Current Assets in the accompanying balance sheets and amortized over the life of the contract, with the intrinsic value method applied at each interim period. For fiscal years 2016 and 2017 the Partnership has a weather hedge contract with Swiss Re under which the Partnership is entitled to receive a payment of $35,000 per heating degree-day shortfall, when the accumulated number of heating degree-days in the entire hedge period is less than approximately 92.5% of the ten year average, the Payment Threshold as defined in the contract. The hedge covers the five month period from November 1, through March 31, taken as a whole, and has a maximum payout of $12.5 million for each respective fiscal year. The amount due to the Partnership at March 31, 2016 is $12.5 million based on the degree-day shortfall experienced during the most recent five month hedge period. In April 2016, the Partnership received $12.5 million from Swiss Re.
New England Teamsters and Trucking Industry Pension Fund ("the NETTI Fund") Liability	New England Teamsters and Trucking Industry Pension Fund (“the NETTI Fund”) Liability As of March 31, 2016 we had $0.1 million and $17.6 million included in the captions Accrued Expenses and Other Current Liabilities and Other Long-Term Liabilities, respectively, on our condensed consolidated balance sheet representing the remaining balance of the NETTI withdrawal liability. Based on the borrowing rates currently available to the Partnership for long-term financing of a similar maturity, the fair value of the NETTI withdrawal liability as of March 31, 2016 was $17.1 million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace the latest revenue recognition guidance in GAAP when it becomes effective. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2019, with early adoption permitted beginning in the first quarter of fiscal 2018. The standard permits the use of either the retrospective or cumulative effect transition method. The Partnership is evaluating the effect that ASU No. 2014-09 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The update requires debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability instead of being presented as an asset. The update requires retrospective application and represents a change in accounting principle. The update is effective for our annual reporting period beginning in the first quarter of fiscal 2017, with early adoption permitted. The impact of ASU No. 2015-03 will be limited to the presentation of debt issuance cost on our balance sheet. In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. The update changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2018, with early adoption permitted. The Partnership does not expect ASU No. 2015-11 to have a material impact on its consolidated financial statements and related disclosures. In September 2015, the FASB issued ASU No. 2015-16, Simplifying the Accounting for Measurement-Period Adjustments, which requires an acquiring entity to recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amounts are determined. The acquiring entity is required to record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. In addition, the acquiring entity is to present separately on the face of its income statement or disclose in the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods as if the adjustment to the provisional amounts had been recognized as of the acquisition date. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2017. The Partnership does not expect ASU No. 2015-16 to have a material impact on its consolidated financial statements and related disclosures. In November 2015, FASB issued ASU No. 2015-17, Income Taxes - Balance Sheet Classification of Deferred Taxes, which eliminates the requirement for companies to present deferred tax assets and liabilities as current and non-current in a classified balance sheet. Instead, companies will be required to classify all deferred tax assets and liabilities as non-current. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2018, with early adoption permitted. The standard permits the use of either the prospective or retrospective transition method. The Partnership is evaluating the effect that ASU No. 2015-17 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption. In February 2016, the FASB issued ASU No. 2016-02, Leases. The update requires all leases with a term greater than twelve months to be recognized on the balance sheet through a right-of-use asset and a lease liability, and the disclosure of key information pertaining to leasing arrangements. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2020, with early adoption permitted. The Partnership is evaluating the effect that ASU No. 2016-02 will have on its consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method nor has it determined the timing of adoption.
