Summary of Significant Accounting Policies (Policies) | 6 Months Ended
--- | ---
Mar. 31, 2017
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, 2017, 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, 2016.
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.
Cash, Cash Equivalents, and Restricted Cash | Cash, cash equivalents, and restricted cash At March 31, 2017, the $53.1 million of cash, cash equivalents, and restricted cash on the condensed consolidated statement of cash flows is composed of $52.9 million of cash and cash equivalents and $0.3 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that are required by state insurance regulations to remain in the captive insurance company as cash.
Investments | Investments The investments are held by our captive insurance company in an irrevocable trust as collateral for workers’ compensation and automobile liability claims incurred and expected to be incurred in fiscal 2017. The collateral is required by a third party insurance carrier that insures per claim amounts above a set deductible. Due to the expected timing of claim payments, the nature of the collateral agreement with the carrier, and our captive insurance company’s source of other operating cash, the collateral is not expected to be used to pay obligations within the next twelve months. Investments are currently comprised of $11.3 million of Level 1 debt securities and $0.3 million of mutual funds measured at net asset value.
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 (EITF 99-2). 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, 2017 and 2018, the Partnership has weather hedge contracts 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, for each respective fiscal year. The ultimate amount due to the Partnership (if any) is based on the entire five month accumulated calculation for the hedge period and has a maximum payout of $12.5 million for each respective fiscal year. In accordance with ASC 815-45-15, as of December 31, 2015, the Partnership recorded a credit of $12.5 million under this contract that reduced delivery and branch expenses. No credit was recorded as of March 31, 2017.
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, 2017, we had $0.2 million and $17.4 million balances 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 Fund 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 Fund withdrawal liability as of March 31, 2017 was $21.7 million. We utilized Level 2 inputs in the fair value hierarchy of valuation techniques to determine the fair value of this liability.
Recently Adopted Accounting Pronouncements | Recently Adopted Accounting Pronouncements In April 2015, the FASB issued Accounting Standards Update (“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 Partnership retrospectively adopted the ASU effective December 31, 2016. As a result of the adoption, certain prior year balances changed to conform to the current year presentation as follows: deferred charges and other assets, net decreased from $11.9 million to $11.1 million and long-term debt decreased from $76.3 million to $75.4 million. 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. The Partnership adopted the ASU effective December 31, 2016. The adoption of ASU No. 2015-16 did not have an impact on the Partnership’s consolidated financial statements and related disclosures. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flow (Topic 230): Restricted cash. The update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Partnership adopted the ASU effective December 31, 2016. The adoption of ASU No. 2016-18 did not have a material impact on the Partnership’s consolidated financial statements and related disclosures.
Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements In May 2014, the FASB issued 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. The FASB has also issued several updates to ASU 2014-09. This ASU will replace most existing 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 in the process of evaluating the effect that ASU 2014-09 will have on its revenue streams, consolidated financial statements and related disclosures. The Partnership has not yet selected a transition method, nor does it intend to early adopt. 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 has not determined the timing of adoption, but does not expect ASU No. 2015-11 to have a material impact on its consolidated financial statements and related disclosures. 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 by calculating the discounted present value of such leases and accounting for them through a right-of-use asset and an offsetting 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 does not intend to early adopt. The Partnership is continuing to evaluate the effect that ASU No. 2016-02 could have on its consolidated financial statements and related disclosures, but has not yet selected a transition method. The new guidance will materially change how we account for operating leases for office space, trucks and other equipment. Upon adoption, we expect to recognize discounted right-of-use assets and offsetting lease liabilities related to our operating leases of office space, trucks and other equipment. As of March 31, 2017, the undiscounted future minimum lease payments through 2032 for such operating leases are approximately $118.9 million, but what the range of reasonable discount rates will be at the time of adoption and what amount of leasing activity is expected between March 31, 2017, and the date of adoption, are currently unknown. For this reason we are unable to estimate the discounted right-of-use assets and lease liabilities as of the date of adoption. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses. The update broadens the information that an entity should consider in developing expected credit loss estimates, eliminates the probable initial recognition threshold, and allows for the immediate recognition of the full amount of expected credit losses. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2021, with early adoption permitted in the first quarter of fiscal 2020. The Partnership is evaluating the effect that ASU No. 2016-13 will have on its consolidated financial statements and related disclosures, but has not yet determined the timing of adoption. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flow (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The update addresses the issues of debt prepayment or debt extinguishment costs, settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2019, with early adoption permitted. The Partnership has not determined the timing of adoption, but does not expect ASU 2016-15 to have a material impact on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the definition of a business. The update clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2019, with early adoption permitted. The Partnership has not determined the timing of adoption, but does not expect ASU 2017-01 to have a material impact on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 230): Simplifying the test for goodwill impairment. The update simplifies how an entity is required to test goodwill for impairment. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, but not exceed the total amount of goodwill allocated to the reporting unit. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2021, with early adoption permitted. The Partnership has not determined the timing of adoption, but does not expect ASU 2017-04 to have a material impact on its consolidated financial statements and related disclosures.
