Partnership Organization And Formation [Abstract]
Partnership Organization and Formation	1. Partnership Organization and Formation Suburban Propane Partners, L.P. (the “Partnership”) is a publicly traded Delaware limited partnership principally engaged, through its operating partnership and subsidiaries, in the retail marketing and distribution of propane, fuel oil and refined fuels, as well as the marketing of natural gas and electricity in deregulated markets. In addition, to complement its core marketing and distribution businesses, the Partnership services a wide variety of home comfort equipment, particularly for heating and ventilation. The publicly traded limited partner interests in the Partnership are evidenced by common units traded on the New York Stock Exchange (“Common Units”), with 61,734,551 Common Units outstanding at June 29, 2019. The holders of Common Units are entitled to participate in distributions and exercise the rights and privileges available to limited partners under the Third Amended and Restated Agreement of Limited Partnership (the “Partnership Agreement”), as amended. Rights and privileges under the Partnership Agreement include, among other things, the election of all members of the Board of Supervisors and voting on the removal of the general partner. Suburban Propane, L.P. (the “Operating Partnership”), a Delaware limited partnership, is the Partnership’s operating subsidiary formed to operate the propane business and assets. In addition, Suburban Sales & Service, Inc. (the “Service Company”), a subsidiary of the Operating Partnership, was formed to operate the service work and appliance and parts businesses of the Partnership. The Operating Partnership, together with its direct and indirect subsidiaries, accounts for substantially all of the Partnership’s assets, revenues and earnings. The Partnership, the Operating Partnership and the Service Company commenced operations in March 1996 in connection with the Partnership’s initial public offering. The general partner of both the Partnership and the Operating Partnership is Suburban Energy Services Group LLC (the “General Partner”), a Delaware limited liability company, the sole member of which is the Partnership’s Chief Executive Officer. Other than as a holder of 784 Common Units that will remain in the General Partner, the General Partner does not have any economic interest in the Partnership or the Operating Partnership. The Partnership’s fuel oil and refined fuels, natural gas and electricity and services businesses are structured as either limited liability companies that are treated as corporations or corporate entities (collectively referred to as the “Corporate Entities”) and, as such, are subject to corporate level U.S. income tax. Suburban Energy Finance Corp., a direct 100%-owned subsidiary of the Partnership, was formed on November 26, 2003 to serve as co-issuer, jointly and severally with the Partnership, of the Partnership’s senior notes.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Presentation	2. Basis of Presentation Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Partnership, the Operating Partnership and all of its direct and indirect subsidiaries. All significant intercompany transactions and account balances have been eliminated. The Partnership consolidates the results of operations, financial condition and cash flows of the Operating Partnership as a result of the Partnership’s 100% limited partner interest in the Operating Partnership. The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). They include all adjustments that the Partnership considers necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed. These financial statements should be read in conjunction with the financial statements included in the Partnership’s Annual Report on Form 10-K for the fiscal year ended September 29, 2018. Due to the seasonal nature of the Partnership’s operations, the results of operations for interim periods are not necessarily indicative of the results to be expected for a full year. Fiscal Period. The Partnership uses a 52/53 week fiscal year which ends on the last Saturday in September. The Partnership’s fiscal quarters are generally thirteen weeks in duration. When the Partnership’s fiscal year is 53 weeks long, the corresponding fourth quarter is fourteen weeks in duration. Revenue Recognition. On September 30, 2018, the first day of fiscal 2019, the Partnership adopted the new accounting guidance regarding revenue recognition under the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”) and all related amendments using the full retrospective method. ASU 2014-09 provides a five-step model to be applied to all contracts with customers. The five steps are to identify the contract(s) with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when each performance obligation is satisfied. The adoption of this standard had no impact on the Partnership’s condensed consolidated statements of financial position, operations or cash flows. Revenue is recognized by the Partnership when goods or services promised in a contract with a customer have been transferred, and no further performance obligation on that transfer is required, in an amount that reflects the consideration expected to be received. sales of propane, fuel oil and refined fuels is met at the time product is delivered to the customer. Revenue from the sale of appliances and equipment is recognized at the time of sale or when installation is complete, as defined by the performance obligations included within the related customer contract. Revenue from repairs, maintenance and other service activities is recognized upon completion of the service. Revenue from the sale of natural gas and electricity is recognized based on customer usage as determined by meter readings for amounts delivered, an immaterial amount of which may be unbilled at the end of each accounting period. The Partnership defers the recognition of revenue for annually billed tank rent, maintenance service contracts, fixed price contracts and budgetary programs where customer consideration is received at the start of the contract period, establishing contract liabilities which are disclosed as customer deposits and advances on the condensed consolidated balance sheets. Deliveries to customers enrolled in budgetary programs that exceed billings to those customers establish contract assets which are included in accounts receivable on the condensed consolidated balance sheets. The Partnership ratably recognizes revenue over the applicable term for tank rent and maintenance service agreements, which is generally one year The Partnership incurs incremental direct costs, such as commissions to its salesforce, to obtain certain contracts. These costs are expensed as incurred, consistent with the practical expedients issued by the FASB, since the expected amortization period is one year or less. The Partnership generally determines selling prices based on, among other things, the current weighted average cost and the current replacement cost of the product at the time of delivery, plus an applicable margin. Except for tank rental agreements, maintenance service contracts, fixed price contracts and budgetary programs, customer p ayments for the satisfaction of a performance obligation are due upon receipt. Fair Value Measurements. The Partnership measures certain of its assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants – in either the principal market or the most advantageous market. The principal market is the market with the greatest level of activity and volume for the asset or liability. The common framework for measuring fair value utilizes a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest. • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices in active markets for similar assets or liabilities; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable. Business Combinations. The Partnership accounts for business combinations using the acquisition method and accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired, including the amount assigned to identifiable intangible assets. The primary drivers that generate goodwill are the value of synergies between the acquired entities and the Partnership, and the acquired assembled workforce, neither of which qualifies as an identifiable intangible asset. Identifiable intangible assets with finite lives are amortized over their useful lives. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date. The Partnership expenses all acquisition-related costs as incurred. Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US 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 revenues and expenses during the reporting period. Estimates have been made by management in the areas of self-insurance and litigation reserves, pension and other postretirement benefit liabilities and costs, valuation of derivative instruments, depreciation and amortization of long-lived assets, asset impairment assessments, tax valuation allowances, allowances for doubtful accounts, and purchase price allocation for acquired businesses. The Partnership uses Society of Actuaries life expectancy information when developing the annual mortality assumptions for the pension and postretirement benefit plans, which are used to measure net periodic benefit costs and the obligation under these plans. Actual results could differ from those estimates, making it reasonably possible that a material change in these estimates could occur in the near term. Reclassifications. Certain prior period amounts have been reclassified to conform to the current period presentation. See Recently Adopted Accounting Pronouncements, below. Recently Issued Accounting Pronouncements. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). This update eliminates the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. In testing goodwill for impairment, an entity may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment indicates that goodwill impairment is more likely than not, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit to its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective for the first interim period within annual reporting periods beginning after December 15, 2019, which will be the Partnership’s first quarter of fiscal 2021. Early adoption of ASU 2017-04 is permitted. The Partnership does not expect that the adoption of ASU 2017-04 will have a material impact on the Partnership’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”). The standard amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 is effective for the first interim period within annual reporting periods beginning after December 15, 2018, which will be the Partnership’s first quarter of fiscal 2020. Early adoption of ASU 2016-02 is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Partnership is currently evaluating the impact of adopting ASU 2016-02 on the Partnership’s consolidated financial statements. Recently Adopted Accounting Pronouncements. During the first quarter of fiscal 2019, the Partnership adopted new accounting guidance under ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”), which has been applied retrospectively. This update required separate disclosure below Operating income on the face of the condensed consolidated statements of operations for certain components of net periodic pension cost and net periodic postretirement cost. The adoption of this standard had no material impact on the Partnership’s condensed consolidated financial statements other than to classify certain components of net periodic benefit costs on the condensed consolidated statements of operations from Operating expenses to Other, net. Refer to Note 14, “Pension Plans and Other Postretirement Benefits.” In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). This update addresses eight specific cash flow issues and is intended to reduce diversity in practice on how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The adoption of this standard had no material impact on the Partnership’s condensed consolidated statements of cash flows. See also Revenue Recognition, above.

Fair Value Disclosures [Abstract]
Financial Instruments and Risk Management	5 . Financial Instruments and Risk Management Cash and Cash Equivalents. The Partnership considers all highly liquid instruments purchased with an original maturity of three months or less to be cash equivalents. The carrying amount approximates fair value because of the short-term maturity of these instruments. Derivative Instruments and Hedging Activities Commodity Price Risk . Given the retail nature of its operations, the Partnership maintains a certain level of priced physical inventory to help ensure its field operations have adequate supply commensurate with the time of year. The Partnership’s strategy is to keep its physical inventory priced relatively close to market for its field operations. The Partnership enters into a combination of exchange-traded futures and option contracts and, in certain instances, over-the-counter options and swap contracts (collectively, “derivative instruments”) to hedge price risk associated with propane and fuel oil physical inventories, as well as future purchases of propane or fuel oil used in its operations and to help ensure adequate supply during periods of high demand. In addition, the Partnership sells propane and fuel oil to customers at fixed prices, and enters into derivative instruments to hedge a portion of its exposure to fluctuations in commodity prices as a result of selling the fixed price contracts. Under this risk management strategy, realized gains or losses on derivative instruments will typically offset losses or gains on the physical inventory once the product is sold or delivered as it pertains to fixed price contracts. All of the Partnership’s derivative instruments are reported on the condensed consolidated balance sheet at their fair values. In addition, in the course of normal operations, the Partnership routinely enters into contracts such as forward priced physical contracts for the purchase or sale of propane and fuel oil that qualify for and are designated as normal purchase or normal sale contracts. Such contracts are exempted from the fair value accounting requirements and are accounted for at the time product is purchased or sold under the related contract. The Partnership does not use derivative instruments for speculative trading purposes. Market risks associated with derivative instruments are monitored daily for compliance with the Partnership’s Hedging and Risk Management Policy which includes volume limits for open positions. Priced on-hand inventory is also reviewed and managed daily as to exposures to changing market prices. On the date that derivative instruments are entered into, other than those designated as normal purchases or normal sales, the Partnership makes a determination as to whether the derivative instrument qualifies for designation as a hedge. Changes in the fair value of derivative instruments are recorded each period in current period earnings or other comprehensive income (“OCI”), depending on whether the derivative instrument is designated as a hedge and, if so, the type of hedge. For derivative instruments designated as cash flow hedges, the Partnership formally assesses, both at the hedge contract’s inception and on an ongoing basis, whether the hedge contract is highly effective in offsetting changes in cash flows of hedged items. Changes in the fair value of derivative instruments designated as cash flow hedges are reported in OCI to the extent effective and reclassified into earnings during the same period in which the hedged item affects earnings. The mark-to-market gains or losses on ineffective portions of cash flow hedges are recognized in earnings immediately. Changes in the fair value of derivative instruments that are not designated as cash flow hedges, and that do not meet the normal purchase and normal sale exemption, are recorded within earnings as they occur. Cash flows associated with derivative instruments are reported as operating activities within the condensed consolidated statement of cash flows. Interest Rate Risk . A portion of the Partnership’s borrowings bear interest at prevailing interest rates based upon, at the Operating Partnership’s option, LIBOR plus an applicable margin or the base rate, defined as the higher of the Federal Funds Rate plus ½ of 1% or the agent bank’s prime rate, or LIBOR plus 1%, plus the applicable margin. The applicable margin is dependent on the level of the Partnership’s total leverage (the ratio of total debt to income before deducting interest expense, income taxes, depreciation and amortization (“EBITDA”)). Therefore, the Partnership is subject to interest rate risk on the variable component of the interest rate. From time to time, the Partnership manages part of its variable interest rate risk by entering into interest rate swap agreements. The interest rate swaps have been designated as, and are accounted for as, cash flow hedges. The fair value of the interest rate swaps are determined using an income approach, whereby future settlements under the swaps are converted into a single present value, with fair value being based on the value of current market expectations about those future amounts. Changes in the fair value are recognized in OCI until the hedged item is recognized in earnings. However, due to changes in the underlying interest rate environment, the corresponding value in OCI is subject to change prior to its impact on earnings. Valuation of Derivative Instruments . The Partnership measures the fair value of its exchange-traded options and futures contracts using quoted market prices found on the New York Mercantile Exchange (the “NYMEX”) (Level 1 inputs); the fair value of its swap contracts using quoted forward prices, and the fair value of its interest rate swaps using model-derived valuations driven by observable projected movements of the 3-month LIBOR (Level 2 inputs); and the fair value of its over-the-counter options contracts using Level 3 inputs. The Partnership’s over-the-counter options contracts are valued based on an internal option model. The inputs utilized in the model are based on publicly available information as well as broker quotes. The significant unobservable inputs used in the fair value measurements of the Partnership’s over-the-counter options contracts are interest rate and market volatility. The following summarizes the fair value of the Partnership’s derivative instruments and their location in the condensed consolidated balance sheets as of June 29, 2019 and September 29, 2018, respectively: As of June 29, 2019 As of September 29, 2018 Asset Derivatives Location Fair Value Location Fair Value Derivatives not designated as hedging instruments: Commodity-related derivatives Other current assets $ 5,253 Other current assets $ 14,875 Other assets — Other assets 13 $ 5,253 $ 14,888 Liability Derivatives Location Fair Value Location Fair Value Derivatives not designated as hedging instruments: Commodity-related derivatives Other current liabilities $ 3,379 Other current liabilities $ 6,122 Other liabilities 436 Other liabilities 167 $ 3,815 $ 6,289 The following summarizes the reconciliation of the beginning and ending balances of assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs: Fair Value Measurement Using Significant Unobservable Inputs (Level 3) Nine Months Ended Nine Months Ended June 29, 2019 June 30, 2018 Assets Liabilities Assets Liabilities Beginning balance of over-the-counter options $ 1,546 $ 361 $ 4,108 $ 737 Beginning balance realized during the period (1,488 ) (361 ) (3,277 ) (737 ) Contracts purchased during the period 434 — 1,352 158 Change in the fair value of outstanding contracts 997 — (800 ) — Ending balance of over-the-counter options $ 1,489 $ — $ 1,383 $ 158 As of June 29, 2019 and September 29, 2018, the Partnership’s outstanding commodity-related derivatives had a weighted average maturity of approximately five and four months, respectively. The effect of the Partnership’s derivative instruments on the condensed consolidated statements of operations and the condensed consolidated statements of comprehensive income, as applicable, for the three and nine months ended June 29, 2019 and June 30, 2018 are as follows: Three Months Ended June 29, 2019 Three Months Ended June 30, 2018 Derivatives Not Designated as Hedging Instruments Unrealized Gains (Losses) Recognized in Income Unrealized Gains (Losses) Recognized in Income Location Amount Location Amount Commodity-related derivatives Cost of products sold $ 138 Cost of products sold $ 3,806 Nine Months Ended June 29, 2019 Nine Months Ended June 30, 2018 Derivatives Not Designated as Hedging Instruments Unrealized Gains (Losses) Recognized in Income Unrealized Gains (Losses) Recognized in Income Location Amount Location Amount Commodity-related derivatives Cost of products sold $ (7,252 ) Cost of products sold $ (1,421 ) The following table presents the fair value of the Partnership’s recognized derivative assets and liabilities on a gross basis and amounts offset on the condensed consolidated balance sheets subject to enforceable master netting arrangements or similar agreements: As of June 29, 2019 As of September 29, 2018 Net amounts Net amounts presented in the presented in the Gross amounts Effects of netting balance sheet Gross amounts Effects of netting balance sheet Asset Derivatives Commodity-related derivatives $ 16,852 $ (11,599 ) $ 5,253 $ 23,181 $ (8,293 ) $ 14,888 Liability Derivatives Commodity-related derivatives $ 15,414 $ (11,599 ) $ 3,815 $ 14,582 $ (8,293 ) $ 6,289 The Partnership had $3,891 and $-0- posted cash collateral as of June 29, 2019 and September 29, 2018, respectively, with its brokers for outstanding commodity-related derivatives.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangible Assets	7 . Goodwill and Other Intangible Assets Goodwill represents the excess of the purchase price over the fair value of net assets acquired. Goodwill is subject to an impairment review at a reporting unit level, on an annual basis as of the end of fiscal July of each year, or when an event occurs or circumstances change that would indicate potential impairment. The Partnership has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary. However, if an entity concludes otherwise, then it is required to perform the first step of the two-step impairment test. Under the two-step impairment test, the Partnership assesses the carrying value of goodwill at a reporting unit level based on an estimate of the fair value of the respective reporting unit. Fair value of the reporting unit is estimated using discounted cash flow analyses taking into consideration estimated cash flows in a ten-year projection period and a terminal value calculation at the end of the projection period. If the fair value of the reporting unit exceeds its carrying value, the goodwill associated with the reporting unit is not considered to be impaired. If the carrying value of the reporting unit exceeds its fair value, an impairment loss is recognized to the extent that the carrying amount of the associated goodwill, if any, exceeds the implied fair value of the goodwill. The carrying values of goodwill assigned to the Partnership’s operating segments are as follows: Fuel oil and Natural gas Propane refined fuels and electricity Total Balance as of September 29, 2018 Goodwill $ 1,081,132 $ 10,900 $ 7,900 $ 1,099,932 Accumulated adjustments — (6,462 ) — (6,462 ) $ 1,081,132 $ 4,438 $ 7,900 $ 1,093,470 Fiscal 2019 Activity Goodwill acquired (1) $ 4,615 $ — $ — $ 4,615 Balance as of June 29, 2019 Goodwill $ 1,085,747 $ 10,900 $ 7,900 $ 1,104,547 Accumulated adjustments — (6,462 ) — (6,462 ) $ 1,085,747 $ 4,438 $ 7,900 $ 1,098,085 Other intangible assets consist of the following: As of June 29, September 29, 2019 2018 Customer relationships (1) $ 507,159 $ 499,432 Non-compete agreements (1) 35,440 33,540 Other 1,967 1,967 544,566 534,939 Less: accumulated amortization Customer relationships (370,965 ) (330,571 ) Non-compete agreements (29,579 ) (27,836 ) Other (1,418 ) (1,349 ) (401,962 ) (359,756 ) $ 142,604 $ 175,183 (1) Reflects the impact from acquisitions (See Note 4).

Net Income Per Common Unit	8 . Net Income Per Common Unit Computations of basic income per Common Unit are performed by dividing net income by the weighted average number of outstanding Common Units, and vested (and unissued) restricted units granted under the Partnership’s Restricted Unit Plans, as defined below, to retirement-eligible grantees. Computations of diluted income per Common Unit are performed by dividing net income by the weighted average number of outstanding Common Units and unissued restricted units granted under the Restricted Unit Plans. In computing diluted net income per Common Unit, weighted average units outstanding used to compute basic net income per Common Unit were increased by 299,569 and 237,697 units for the nine months ended June 29, 2019 and June 30, 2018, respectively, to reflect the potential dilutive effect of the unvested restricted units outstanding using the treasury stock method. Diluted loss per unit for the three months ended June 29, 2019 and June 30, 2018 does not include unvested Restricted Units (See Note 11) as their effect would be anti-dilutive.

The 2027 Senior Notes were issued at 100% of the principal amount and require semi-annual interest payments in March and September. The net proceeds from the issuance of the 2027 Senior Notes, along with borrowings under the Revolving Credit Facility, were used to repurchase, satisfy and discharge all of the Partnership’s then-outstanding 7.375% senior notes due in 2021. The Partnership’s obligations under the 2024 Senior Notes, 2025 Senior Notes and 2027 Senior Notes (collectively, the “Senior Notes”) are unsecured and rank senior in right of payment to any future subordinated indebtedness and equally in right of payment with any future senior indebtedness. The Senior Notes are structurally subordinated to, which means they rank effectively behind, any debt and other liabilities of the Operating Partnership. The Partnership is permitted to redeem some or all of the Senior Notes at redemption prices and times as specified in the indentures governing the Senior Notes. The Senior Notes each have a change of control provision that would require the Partnership to offer to repurchase the notes at 101% of the principal amount repurchased, if a change of control, as defined in the indenture, occurs and is followed by a rating decline (a decrease in the rating of the notes by either Moody’s Investors Service or Standard and Poor’s Rating Group by one or more gradations) within 90 days Credit Agreement. The Operating Partnership has an amended and restated credit agreement, dated March 3, 2016 and further amended on May 1, 2017 (the “Amended Credit Agreement”) that provides for a five-year $500,000 revolving credit facility (the “Revolving Credit Facility”) with a maturity date of March 3, 2021, of which $127,200 and $143,600 was outstanding as of June 29, 2019 and September 29, 2018, respectively. Borrowings under the Revolving Credit Facility may be used for general corporate purposes, including working capital, capital expenditures and acquisitions. The Operating Partnership has the right to prepay any borrowings under the Revolving Credit Facility, in whole or in part, without penalty at any time prior to maturity. The Amended Credit Agreement contains certain restrictive and affirmative covenants applicable to the Operating Partnership, its subsidiaries and the Partnership, as well as certain financial covenants, including (a) requiring the Partnership’s Consolidated Interest Coverage Ratio, as defined in the Amended Credit Agreement, to be not less than 2.5 to 1.0 as of the end of any fiscal quarter, (b) prohibiting the Total Consolidated Leverage Ratio, as defined in the Amended Credit Agreement, of the Partnership from being greater than 5.5 to 1.0 for the fiscal quarter ending in December 2018 and for each fiscal quarter thereafter, and (c) prohibiting the Senior Secured Consolidated Leverage Ratio, as defined in the Amended Credit Agreement, of the Operating Partnership from being greater than 3.0 to 1.0 as of the end of any fiscal quarter. The Partnership and certain subsidiaries of the Operating Partnership act as guarantors with respect to the obligations of the Operating Partnership under the Amended Credit Agreement pursuant to the terms and conditions set forth therein. The obligations under the Amended Credit Agreement are secured by liens on substantially all of the personal property of the Partnership, the Operating Partnership and their subsidiaries, as well as mortgages on certain real property. Borrowings under the Revolving Credit Facility bear interest at prevailing interest rates based upon, at the Operating Partnership’s option, LIBOR plus the Applicable Rate, or the base rate, defined as the higher of the Federal Funds Rate plus ½ of 1%, the administrative agent bank’s prime rate, or LIBOR plus 1%, plus in each case the Applicable Rate. The Applicable Rate is dependent upon the Partnership’s Total Consolidated Leverage Ratio. As of June 29, 2019, the interest rate for borrowings under the Revolving Credit Facility was approximately 4.8%. The interest rate and the Applicable Rate will be reset following the end of each calendar quarter. As of June 29, 2019, the Partnership had standby letters of credit issued under the Revolving Credit Facility of $65,826 which expire periodically through November 1, 2020. The Amended Credit Agreement and the Senior Notes both contain various restrictive and affirmative covenants applicable to the Operating Partnership, its subsidiaries and the Partnership, respectively, including (i) restrictions on the incurrence of additional indebtedness, and (ii) restrictions on certain liens, investments, guarantees, loans, advances, payments, mergers, consolidations, distributions, sales of assets and other transactions. Under the Amended Credit Agreement and the indentures governing the Senior Notes, the Operating Partnership and the Partnership are generally permitted to make cash distributions equal to available cash, as defined, as of the end of the immediately preceding quarter, if no event of default exists or would exist upon making such distributions, and with respect to the indentures governing the Senior Notes, the Partnership’s Consolidated Fixed Charge Coverage Ratio, as defined, is greater than 1.75 to 1. The Partnership and the Operating Partnership were in compliance with all covenants and terms of the Senior Notes and the Amended Credit Agreement as of June 29, 2019. The aggregate amounts of long-term debt maturities subsequent to June 29, 2019 are as follows: fiscal 2019: $-0-; fiscal 2020: $-0-; fiscal 2021: $127,200; fiscal 2022: $-0-; fiscal 2023: $-0-; and thereafter: $1,125,000.

Distributions of Available Cash	10 . Distributions of Available Cash The Partnership makes distributions to its partners no later than 45 days after the end of each fiscal quarter in an aggregate amount equal to its Available Cash for such quarter. Available Cash, as defined in the Partnership Agreement, generally means all cash on hand at the end of the respective fiscal quarter less the amount of cash reserves established by the Board of Supervisors in its reasonable discretion for future cash requirements. These reserves are retained for the proper conduct of the Partnership’s business, the payment of debt principal and interest and for distributions during the next four quarters. On July 25, 2019, the Partnership announced a quarterly distribution of $0.60 per Common Unit, or $2.40 per Common Unit on an annualized basis, in respect of the third quarter of fiscal 2019, payable on August 13, 2019 to holders of record on August 6, 2019.

Unit-Based Compensation Arrangements	1 1 . Unit-Based Compensation Arrangements The Partnership recognizes compensation cost over the respective service period for employee services received in exchange for an award of equity, or equity-based compensation, based on the grant date fair value of the award. The Partnership measures liability awards under an equity-based payment arrangement based on remeasurement of the award’s fair value at the conclusion of each interim and annual reporting period until the date of settlement, taking into consideration the probability that the performance conditions will be satisfied. Restricted Unit Plans. On July 22, 2009, the Partnership adopted the Suburban Propane Partners, L.P. 2009 Restricted Unit Plan, as amended (the “2009 Restricted Unit Plan”), which authorizes the issuance of Common Units to executives, managers and other employees and members of the Board of Supervisors of the Partnership. The total number of Common Units authorized for issuance under the 2009 Restricted Unit Plan was 2,400,000 as of June 29, 2019. As of that date, there were no units available for future awards under the 2009 Restricted Unit Plan. At the Partnership’s Tri-Annual Meeting held on May 15, 2018, the Unitholders approved the Partnership's 2018 Restricted Unit Plan (the “2018 Restricted Unit Plan” and together with the 2009 Restricted Unit Plan, the “Restricted Unit Plans”) authorizing the issuance of up to 1,800,000 Common Units. Unless otherwise stipulated by the Compensation Committee of the Partnership’s Board of Supervisors on or before the grant date, all currently outstanding restricted unit awards will vest 33.33% on each of the first three anniversaries of the award grant date. Participants in the Restricted Unit Plans are not eligible to receive quarterly distributions on, or vote, their respective restricted units until vested. Restricted units cannot be sold or transferred prior to vesting. The value of the restricted unit is established by the market price of the Common Unit on the date of grant, net of estimated future distributions during the vesting period. Restricted units are subject to forfeiture in certain circumstances as defined in the Restricted Unit Plans documents. Compensation expense for the unvested awards is recognized ratably over the vesting periods and is net of estimated forfeitures. During the nine months ended June 29, 2019, the Partnership awarded 618,268 restricted units under the Restricted Unit Plans at an aggregate grant date fair value of $11,212. The following is a summary of activity for the Restricted Unit Plans for the nine months ended June 29, 2019: Weighted Restricted Grant Date Fair Units Value Per Unit Outstanding September 29, 2018 696,131 $ 19.47 Awarded 618,268 18.13 Forfeited (5,205 ) (18.37 ) Vested (319,510 ) (21.08 ) Outstanding June 29, 2019 989,684 $ 18.12 As of June 29, 2019, unrecognized compensation cost related to unvested restricted units awarded under the Restricted Unit Plans amounted to $5,340. Compensation cost associated with unvested awards is expected to be recognized over a weighted-average period of 1 year. Compensation expense for the Restricted Unit Plans, net of forfeitures, for the three and nine months ended June 29, 2019 was $2,280 and $8,855, respectively, and $1,715 and $6,862, for the three and nine months ended June 30, 2018, respectively. Distribution Equivalent Rights Plan. On January 17, 2017, the Partnership adopted the Distribution Equivalent Rights Plan (the “DER Plan”), which gives the Compensation Committee of the Partnership’s Board of Supervisors discretion to award distribution equivalent rights (“DERs”) to executive officers of the Partnership. Once awarded, DERs entitle the grantee to a cash payment each time the Board of Supervisors declares a cash distribution on the Partnership’s Common Units, which cash payment will be equal to an amount calculated by multiplying the number of unvested restricted units which are held by the grantee on the record date of the distribution, by the amount of the declared distribution per Common Unit. Compensation expense recognized under the DER Plan for the three and nine months ended June 29, 2019 was $264 and $784, respectively, and $201 and $609 for the three and nine months ended June 30, 2018, respectively. Long-Term Incentive Plan. On August 6, 2013, the Partnership adopted the 2014 Long-Term Incentive Plan (“LTIP”). The LTIP is a non-qualified, unfunded, long-term incentive plan for executive officers and key employees that provides for payment, in the form of cash, of an award of equity-based compensation at the end of a three-year performance period. The level of compensation earned under the LTIP is based on the Partnership’s average distribution coverage ratio over the three-year measurement period. The Partnership’s average distribution coverage ratio is calculated as the Partnership’s average distributable cash flow, as defined by the LTIP, for each of the three years in the measurement period, subject to certain adjustments as set forth in the LTIP, divided by the amount of annualized cash distributions to be paid by the Partnership. As a result of the quarterly remeasurement of the liability for awards under the LTIP, compensation expense recognized for the three and nine months ended June 29, 2019 was $1,271 and $4,470, respectively, and $595 and $2,719, for the three and nine months ended June 30, 2018, respectively. As of June 29, 2019 and September 29, 2018, the Partnership had a liability included within accrued employment and benefit costs (or other liabilities, as applicable) of $9,286 and $4,817, respectively, related to estimated future payments under the LTIP.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	1 2 . Commitments and Contingencies Accrued Insurance. As of June 29, 2019 and September 29, 2018, the Partnership had accrued insurance liabilities of $69,783 and $70,567, respectively, representing the total estimated losses under its general and product, workers’ compensation and automobile liabilities. The Partnership is self-insured for these liabilities, up to predetermined thresholds above which third party insurance applies. For the portion of the estimated liability that exceeds insurance deductibles, the Partnership records an asset within other assets (or prepaid expenses and other current assets, as applicable) related to the amount of the liability expected to be covered by insurance which amounted to $19,069 and $20,837 as of June 29, 2019 and September 29, 2018, respectively. Legal Matters. The Partnership’s operations are subject to operating hazards and risks normally incidental to handling, storing and delivering combustible liquids such as propane. The Partnership has been, and will continue to be, a defendant in various legal proceedings and litigation as a result of these operating hazards and risks, and as a result of other aspects of its business. In this regard, the Partnership’s natural gas and electricity business is currently a defendant in two putative class action suits in the federal district courts of New York and Pennsylvania. The complaints allege a number of claims under various consumer statutes and common law in New York and Pennsylvania regarding pricing offered to electricity customers in those states. The complaint in the Pennsylvania action was dismissed in its entirety by the district court, which dismissal is being appealed by the plaintiff. The complaint in the New York action was dismissed in part by the district court, but causes of action based on the New York consumer statute and breach of contract were allowed to proceed. Based on the nature of the allegations under these suits, the Partnership believes that the suits are without merit and is defending each of these suits vigorously. With respect to these pending suits, the Partnership has determined, based on the allegations and discovery to date, that no reserve for a loss contingency is required. The Partnership is unable to reasonably estimate the possible loss or range of loss, if any, arising from either of these two actions. Although any litigation is inherently uncertain, based on past experience, the information currently available to the Partnership, and the amount of its accrued insurance liabilities, the Partnership does not believe that currently pending or threatened litigation matters, or known claims or known contingent claims, will have a material adverse effect on its results of operations, financial condition or cash flow .

Guarantees [Abstract]
Guarantees	1 3 . Guarantees The Partnership has residual value guarantees associated with certain of its operating leases, related primarily to transportation equipment, with remaining lease periods scheduled to expire periodically through fiscal 2028. Upon completion of the lease period, the Partnership guarantees that the fair value of the equipment will equal or exceed the guaranteed amount, or the Partnership will pay the lessor the difference. Although the fair value of equipment at the end of its lease term has historically exceeded the guaranteed amounts, the maximum potential amount of aggregate future payments the Partnership could be required to make under these leasing arrangements, assuming the equipment is deemed worthless at the end of the lease term, was $17,975 as of June 29, 2019. The fair value of residual value guarantees for outstanding operating leases was de minimis as of June 29, 2019 and September 29, 2018.

The projected annual contribution requirements related to the Partnership’s postretirement health care and life insurance benefit plan for fiscal 2019 is $1,129, of which $718 was contributed during the nine months ended June 29, 2019. The components of net periodic benefit cost are included in the line item Other, net in the condensed consolidated statements of operations. The Partnership contributes to multi-employer pension plans (“MEPPs”) in accordance with various collective bargaining agreements covering union employees. As one of the many participating employers in these MEPPs, the Partnership is responsible with the other participating employers for any plan underfunding. As of June 29, 2019 and September 29, 2018, the Partnership’s estimated obligation to these MEPPs was $21,710 and $22,509, respectively, as a result of its voluntary full withdrawal from certain MEPPs.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	1 6 . Income Taxes For federal income tax purposes, as well as for state income tax purposes in the majority of the states in which the Partnership operates, the earnings attributable to the Partnership and the Operating Partnership are not subject to income tax at the partnership level. With the exception of those states that impose an entity-level income tax on partnerships, the taxable income or loss attributable to the Partnership and to the Operating Partnership, which may vary substantially from the income (loss) before income taxes reported by the Partnership in the condensed consolidated statement of operations, are includable in the federal and state income tax returns of the Common Unitholders. The aggregate difference in the basis of the Partnership’s net assets for financial and tax reporting purposes cannot be readily determined as the Partnership does not have access to each Common Unitholder’s basis in the Partnership. As described in Note 1, the earnings of the Corporate Entities are subject to corporate level federal and state income tax. However, based upon past performance, the Corporate Entities are currently reporting an income tax provision composed primarily of minimum state income taxes. A full valuation allowance has been provided against the deferred tax assets (with the exception of the AMT credit carryforward; see below) based upon an analysis of all available evidence, both negative and positive at the balance sheet date, which, taken as a whole, indicates that it is more likely than not that sufficient future taxable income will not be available to utilize the assets. Management’s periodic reviews include, among other things, the nature and amount of the taxable income and expense items, the expected timing of when assets will be used or liabilities will be required to be reported and the reliability of historical profitability of businesses expected to provide future earnings. Furthermore, management considered tax-planning strategies it could use to increase the likelihood that the deferred tax assets will be realized. On December 22, 2017, the Tax Cuts and Jobs Act (“2017 Act”) was signed into law, which enacted significant changes to U.S. tax and related laws. Some of the provisions of the 2017 Act that could affect the Partnership, the Operating Partnership and their subsidiaries include, but are not limited to, a reduction of the federal corporate income tax rate from 35% to 21%, limitations on the deductibility of net business interest expense, restrictions on the use of net operating loss carryforwards arising in taxable years beginning after December 31, 2017 and full expensing for certain qualified property. In the case of a corporation, the 2017 Act made Alternative Minimum Tax (“AMT”) credit carryforwards fully refundable without regard to future taxable income. Accordingly, the Partnership concluded that the existing valuation allowance on the AMT credit carryforwards of the Corporate Entities should be released as part of accounting for tax reform. The reversal of the valuation allowance resulted in a $1,086 discrete deferred tax benefit being recorded during the first quarter of fiscal 2018. The Partnership remeasured all other federal net deferred tax assets of the Corporate Entities using the new 21% federal income tax rate and correspondingly adjusted the full valuation allowance. The blended corporate tax federal rate requirements of Internal Revenue Code Section 15 do not apply because the Corporate Entities are calendar-year tax filers.

Segment Information

Segment Information	9 Months Ended

Segment Reporting [Abstract]
Segment Information	1 7 . Segment Information The Partnership manages and evaluates its operations in four operating segments, three of which are reportable segments: Propane, Fuel Oil and Refined Fuels, and Natural Gas and Electricity. The chief operating decision maker evaluates performance of the operating segments using a number of performance measures, including gross margins and income before interest expense and provision for income taxes (operating profit). Costs excluded from these profit measures are captured in Corporate and include corporate overhead expenses not allocated to the operating segments. Unallocated corporate overhead expenses include all costs of back office support functions that are reported as general and administrative expenses within the condensed consolidated statements of operations. In addition, certain costs associated with field operations support that are reported in operating expenses within the condensed consolidated statements of operations, including purchasing, training and safety, are not allocated to the individual operating segments. Thus, operating profit for each operating segment includes only the costs that are directly attributable to the operations of the individual segment. The accounting policies of the operating segments are otherwise the same as those described in Note 2, “Summary of Significant Accounting Policies,” in the Partnership’s Annual Report on Form 10-K for the fiscal year ended September 29, 2018. The propane segment is primarily engaged in the retail distribution of propane to residential, commercial, industrial and agricultural customers and, to a lesser extent, wholesale distribution to large industrial end users. In the residential and commercial markets, propane is used primarily for space heating, water heating, cooking and clothes drying. Industrial customers use propane generally as a motor fuel burned in internal combustion engines that power over-the-road vehicles, forklifts and stationary engines, to fire furnaces and as a cutting gas. In the agricultural markets, propane is primarily used for tobacco curing, crop drying, poultry brooding and weed control. The fuel oil and refined fuels segment is primarily engaged in the retail distribution of fuel oil, diesel, kerosene and gasoline to residential and commercial customers for use primarily as a source of heat in homes and buildings. The natural gas and electricity segment is engaged in the marketing of natural gas and electricity to residential and commercial customers in the deregulated energy markets of New York and Pennsylvania. Under this operating segment, the Partnership owns the relationship with the end consumer and has agreements with the local distribution companies to deliver the natural gas or electricity from the Partnership’s suppliers to the customer. Activities in the “all other” category include the Partnership’s service business, which is primarily engaged in the sale, installation and servicing of a wide variety of home comfort equipment, particularly in the areas of heating and ventilation. The following table presents certain data by reportable segment and provides a reconciliation of total operating segment information to the corresponding consolidated amounts for the periods presented: Three Months Ended Nine Months Ended June 29, June 30, June 29, June 30, 2019 2018 2019 2018 Revenues: Propane $ 183,052 $ 205,400 $ 937,468 $ 990,344 Fuel oil and refined fuels 12,921 15,400 83,428 82,414 Natural gas and electricity 7,527 10,403 38,527 43,942 All other 10,712 10,733 36,270 34,795 Total revenues $ 214,212 $ 241,936 $ 1,095,693 $ 1,151,495 Operating (loss) income: Propane $ 21,038 $ 29,245 $ 254,159 $ 249,363 Fuel oil and refined fuels (1,084 ) (891 ) 10,457 10,132 Natural gas and electricity 1,059 2,192 8,772 11,131 All other (5,018 ) (4,607 ) (13,814 ) (14,821 ) Corporate (24,779 ) (21,706 ) (77,734 ) (67,248 ) Total operating (loss) income (8,784 ) 4,233 181,840 188,557 Reconciliation to net (loss) income: Interest expense, net 18,906 19,512 58,041 58,428 Other, net 1,176 1,172 3,527 3,518 Provision for (benefit from) income taxes 175 144 578 (749 ) Net (loss) income $ (29,041 ) $ (16,595 ) $ 119,694 $ 127,360 Depreciation and amortization: Propane $ 26,828 $ 27,875 $ 81,722 $ 83,944 Fuel oil and refined fuels 594 571 1,619 1,866 Natural gas and electricity — — — — All other 49 57 149 163 Corporate 2,680 2,756 7,355 8,620 Total depreciation and amortization $ 30,151 $ 31,259 $ 90,845 $ 94,593 As of June 29, September 29 2019 2018 Assets: Propane $ 1,933,169 $ 1,995,060 Fuel oil and refined fuels 46,772 47,911 Natural gas and electricity 12,035 13,067 All other 3,753 3,363 Corporate 39,414 41,798 Total assets $ 2,035,143 $ 2,101,199

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Principles of Consolidation	Principles of Consolidation. The condensed consolidated financial statements include the accounts of the Partnership, the Operating Partnership and all of its direct and indirect subsidiaries. All significant intercompany transactions and account balances have been eliminated. The Partnership consolidates the results of operations, financial condition and cash flows of the Operating Partnership as a result of the Partnership’s 100% limited partner interest in the Operating Partnership. The accompanying condensed consolidated financial statements are unaudited and have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). They include all adjustments that the Partnership considers necessary for a fair statement of the results of operations, financial position and cash flows for the interim periods presented. Such adjustments consist only of normal recurring items, unless otherwise disclosed. These financial statements should be read in conjunction with the financial statements included in the Partnership’s Annual Report on Form 10-K for the fiscal year ended September 29, 2018. Due to the seasonal nature of the Partnership’s operations, the results of operations for interim periods are not necessarily indicative of the results to be expected for a full year.
Fiscal Period	Fiscal Period. The Partnership uses a 52/53 week fiscal year which ends on the last Saturday in September. The Partnership’s fiscal quarters are generally thirteen weeks in duration. When the Partnership’s fiscal year is 53 weeks long, the corresponding fourth quarter is fourteen weeks in duration.
Revenue Recognition	Revenue Recognition. On September 30, 2018, the first day of fiscal 2019, the Partnership adopted the new accounting guidance regarding revenue recognition under the Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2014-09 “Revenue from Contracts with Customers” (“ASU 2014-09”) and all related amendments using the full retrospective method. ASU 2014-09 provides a five-step model to be applied to all contracts with customers. The five steps are to identify the contract(s) with the customer, identify the performance obligations in the contract, determine the transaction price, allocate the transaction price to the performance obligations in the contract and recognize revenue when each performance obligation is satisfied. The adoption of this standard had no impact on the Partnership’s condensed consolidated statements of financial position, operations or cash flows. Revenue is recognized by the Partnership when goods or services promised in a contract with a customer have been transferred, and no further performance obligation on that transfer is required, in an amount that reflects the consideration expected to be received. sales of propane, fuel oil and refined fuels is met at the time product is delivered to the customer. Revenue from the sale of appliances and equipment is recognized at the time of sale or when installation is complete, as defined by the performance obligations included within the related customer contract. Revenue from repairs, maintenance and other service activities is recognized upon completion of the service. Revenue from the sale of natural gas and electricity is recognized based on customer usage as determined by meter readings for amounts delivered, an immaterial amount of which may be unbilled at the end of each accounting period. The Partnership defers the recognition of revenue for annually billed tank rent, maintenance service contracts, fixed price contracts and budgetary programs where customer consideration is received at the start of the contract period, establishing contract liabilities which are disclosed as customer deposits and advances on the condensed consolidated balance sheets. Deliveries to customers enrolled in budgetary programs that exceed billings to those customers establish contract assets which are included in accounts receivable on the condensed consolidated balance sheets. The Partnership ratably recognizes revenue over the applicable term for tank rent and maintenance service agreements, which is generally one year The Partnership incurs incremental direct costs, such as commissions to its salesforce, to obtain certain contracts. These costs are expensed as incurred, consistent with the practical expedients issued by the FASB, since the expected amortization period is one year or less. The Partnership generally determines selling prices based on, among other things, the current weighted average cost and the current replacement cost of the product at the time of delivery, plus an applicable margin. Except for tank rental agreements, maintenance service contracts, fixed price contracts and budgetary programs, customer p ayments for the satisfaction of a performance obligation are due upon receipt.
Fair Value Measurements	Fair Value Measurements. The Partnership measures certain of its assets and liabilities at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants – in either the principal market or the most advantageous market. The principal market is the market with the greatest level of activity and volume for the asset or liability. The common framework for measuring fair value utilizes a three-level hierarchy to prioritize the inputs used in the valuation techniques to derive fair values. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest. • Level 1: Quoted prices in active markets for identical assets or liabilities. • Level 2: Quoted prices in active markets for similar assets or liabilities; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets. • Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable.
Business Combinations	Business Combinations. The Partnership accounts for business combinations using the acquisition method and accordingly, the assets and liabilities of the acquired entities are recorded at their estimated fair values at the acquisition date. Goodwill represents the excess of the purchase price over the fair value of the net assets acquired, including the amount assigned to identifiable intangible assets. The primary drivers that generate goodwill are the value of synergies between the acquired entities and the Partnership, and the acquired assembled workforce, neither of which qualifies as an identifiable intangible asset. Identifiable intangible assets with finite lives are amortized over their useful lives. The results of operations of acquired businesses are included in the consolidated financial statements from the acquisition date. The Partnership expenses all acquisition-related costs as incurred.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“US 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 revenues and expenses during the reporting period. Estimates have been made by management in the areas of self-insurance and litigation reserves, pension and other postretirement benefit liabilities and costs, valuation of derivative instruments, depreciation and amortization of long-lived assets, asset impairment assessments, tax valuation allowances, allowances for doubtful accounts, and purchase price allocation for acquired businesses. The Partnership uses Society of Actuaries life expectancy information when developing the annual mortality assumptions for the pension and postretirement benefit plans, which are used to measure net periodic benefit costs and the obligation under these plans. Actual results could differ from those estimates, making it reasonably possible that a material change in these estimates could occur in the near term.
Reclassifications	Reclassifications. Certain prior period amounts have been reclassified to conform to the current period presentation. See Recently Adopted Accounting Pronouncements, below.
Recently Issued and Adopted Accounting Pronouncements	Recently Issued Accounting Pronouncements. In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”). This update eliminates the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment. In testing goodwill for impairment, an entity may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative assessment indicates that goodwill impairment is more likely than not, an entity should perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit to its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value, not to exceed the total amount of goodwill allocated to the reporting unit. ASU 2017-04 is effective for the first interim period within annual reporting periods beginning after December 15, 2019, which will be the Partnership’s first quarter of fiscal 2021. Early adoption of ASU 2017-04 is permitted. The Partnership does not expect that the adoption of ASU 2017-04 will have a material impact on the Partnership’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU 2016-02”). The standard amends the existing accounting standards for lease accounting, including requiring lessees to recognize most leases on their balance sheets and making targeted changes to lessor accounting. ASU 2016-02 is effective for the first interim period within annual reporting periods beginning after December 15, 2018, which will be the Partnership’s first quarter of fiscal 2020. Early adoption of ASU 2016-02 is permitted. The new leases standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The Partnership is currently evaluating the impact of adopting ASU 2016-02 on the Partnership’s consolidated financial statements. Recently Adopted Accounting Pronouncements. During the first quarter of fiscal 2019, the Partnership adopted new accounting guidance under ASU 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost” (“ASU 2017-07”), which has been applied retrospectively. This update required separate disclosure below Operating income on the face of the condensed consolidated statements of operations for certain components of net periodic pension cost and net periodic postretirement cost. The adoption of this standard had no material impact on the Partnership’s condensed consolidated financial statements other than to classify certain components of net periodic benefit costs on the condensed consolidated statements of operations from Operating expenses to Other, net. Refer to Note 14, “Pension Plans and Other Postretirement Benefits.” In August 2016, the FASB issued ASU 2016-15, “Classification of Certain Cash Receipts and Cash Payments” (“ASU 2016-15”). This update addresses eight specific cash flow issues and is intended to reduce diversity in practice on how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The adoption of this standard had no material impact on the Partnership’s condensed consolidated statements of cash flows. See also Revenue Recognition, above.

Distribution Equivalent Rights Plan, terms			On January 17, 2017, the Partnership adopted the Distribution Equivalent Rights Plan (the “DER Plan”), which gives the Compensation Committee of the Partnership’s Board of Supervisors discretion to award distribution equivalent rights (“DERs”) to executive officers of the Partnership.  Once awarded, DERs entitle the grantee to a cash payment each time the Board of Supervisors declares a cash distribution on the Partnership’s Common Units, which cash payment will be equal to an amount calculated by multiplying the number of unvested restricted units which are held by the grantee on the record date of the distribution, by the amount of the declared distribution per Common Unit.

Restricted Unit Plans, terms of award			Unless otherwise stipulated by the Compensation Committee of the Partnership’s Board of Supervisors on or before the grant date, all currently outstanding restricted unit awards will vest 33.33% on each of the first three anniversaries of the award grant date.  Participants in the Restricted Unit Plans are not eligible to receive quarterly distributions on, or vote, their respective restricted units until vested.  Restricted units cannot be sold or transferred prior to vesting. The value of the restricted unit is established by the market price of the Common Unit on the date of grant, net of estimated future distributions during the vesting period.  Restricted units are subject to forfeiture in certain circumstances as defined in the Restricted Unit Plans documents. Compensation expense for the unvested awards is recognized ratably over the vesting periods and is net of estimated forfeitures.
