Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	3) Summary of Significant Accounting Policies Basis of Presentation The Consolidated Financial Statements include the accounts of Star Gas Partners, L.P. and its subsidiaries. All material intercompany items and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America 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 revenue and expenses during the reporting period. Actual results could differ from those estimates. Revenue Recognition Sales of heating oil and other fuels are recognized at the time of delivery of the product to the customer and sales of heating and air conditioning equipment are recognized at the time of installation. Revenue from repairs and maintenance service is recognized upon completion of the service. Payments received from customers for equipment service contracts are deferred and amortized into income over the terms of the respective service contracts, on a straight-line basis, which generally do not exceed one year. To the extent that the Partnership anticipates that future costs for fulfilling its contractual obligations under its service maintenance contracts will exceed the amount of deferred revenue currently attributable to these contracts, the Partnership recognizes a loss in current period earnings equal to the amount that anticipated future costs exceed related deferred revenues. Cost of Product Cost of product includes the cost of heating oil, diesel, propane, kerosene, heavy oil, gasoline, throughput costs, barging costs, option costs, and realized gains/losses on closed derivative positions for product sales. Cost of Installations and Service Cost of installations and service includes equipment and material costs, wages and benefits for equipment technicians, dispatchers and other support personnel, subcontractor expenses, commissions and vehicle related costs. Delivery and Branch Expenses Delivery and branch expenses include wages and benefits and department related costs for drivers, dispatchers, garage mechanics, customer service, sales and marketing, compliance, credit and branch accounting, information technology, insurance and operational support. General and Administrative Expenses General and administrative expenses include wages and benefits and department related costs for human resources, finance and partnership accounting, administrative support and supply. Allowance for Doubtful Accounts The allowance for doubtful accounts, which includes the allowance for long-term receivables, is the Partnership's best estimate of the amount of trade receivables that may not be collectible. The allowance is determined at an aggregate level (as opposed to account by account) by grouping accounts based on the type of account and its receivable aging. The allowance is based on both quantitative and qualitative factors, including historical loss experience, historical collection patterns, overdue status, aging trends, and current economic conditions. The Partnership has an established process to periodically review current and past due trade receivable balances to determine the adequacy of the allowance. No single statistic or measurement determines the adequacy of the allowance. The total allowance reflects management's estimate of losses inherent in its trade receivables at the balance sheet date. Different assumptions or changes in economic conditions could result in material changes to the allowance for doubtful accounts. Allocation of Net Income Net income for partners' capital and statement of operations is allocated to the general partner and the limited partners in accordance with their respective ownership percentages, after giving effect to cash distributions paid to the general partner in excess of its ownership interest, if any. Net Income per Limited Partner Unit Income per limited partner unit is computed in accordance with FASB ASC 260-10-05 Earnings Per Share topic, Master Limited Partnerships subtopic (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 results 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. Until the quarter ended March 31, 2009, either the partners had no rights to accrue or receive distributions, or the earnings of the period did not exceed the aggregate distributions. Cash, Accounts Receivable, Notes Receivable, Revolving Credit Facility Borrowings, and Accounts Payable The carrying amount of cash, accounts receivable, notes receivable, revolving credit facility borrowings, and accounts payable approximates fair value because of the short maturity of these instruments. Cash Equivalents The Partnership considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Inventories Liquid product inventories are stated at the lower of cost or market using the weighted average cost method of accounting. All other inventories, representing parts and equipment are stated at the lower of cost or market using the FIFO method. Property, and Equipment Property and equipment are stated at cost. Depreciation is computed over the estimated useful lives of the depreciable assets using the straight-line method. Goodwill and Intangible Assets Goodwill and intangible assets include goodwill, customer lists and covenants not to compete. Goodwill is the excess of cost over the fair value of net assets in the acquisition of a company. In accordance with FASB ASC 350-10-05 Intangibles-Goodwill and Other topic, goodwill and intangible assets with indefinite useful lives are not amortized, but instead are annually tested for impairment. Also in accordance with this standard, intangible assets with definite useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment. The Partnership performs its annual impairment review during its fiscal fourth quarter or more frequently if events or circumstances indicate that the value of goodwill might be impaired. Customer lists are the names and addresses of an acquired company's customers. Based on historical retention experience, these lists are amortized on a straight-line basis over seven to ten years. Trade names are the names of acquired companies. Based on the economic benefit expected and historical retention experience of customers, trade names are amortized on a straight-line basis over seven to twenty years. Covenants not to compete are agreements with the owners of acquired companies and are amortized over the respective lives of the covenants on a straight-line basis, which are generally five years. Business Combinations The Partnership uses the acquisition method of accounting in accordance with FASB ASC 805 Business Combinations. The acquisition method of accounting requires the Partnership to use significant estimates and assumptions, including fair value estimates, as of the business combination date, and to refine those estimates as necessary during the measurement period (defined as the period, not to exceed one year, in which the amounts recognized for a business combination may be adjusted). Each acquired company's operating results are included in the Partnership's consolidated financial statements starting on the date of acquisition. The purchase price is equivalent to the fair value of consideration transferred. Tangible and identifiable intangible assets acquired and liabilities assumed as of the date of acquisition, are recorded at the acquisition date fair value. The separately identifiable intangible assets generally are comprised of customer lists, trade names and covenants not to compete. Goodwill is recognized for the excess of the purchase price over the net fair value of assets acquired and liabilities assumed. Costs that are incurred to complete the business combination such as investment banking, legal and other professional fees are not considered part of consideration transferred, and are charged to general and administrative expense as they are incurred. For any given acquisition, certain contingent consideration may be identified. Estimates of the fair value of liability or asset classified contingent consideration are included under the acquisition method as part of the assets acquired or liabilities assumed. At each reporting date, these estimates are remeasured to fair value, with changes recognized in earnings. Impairment of Long-lived Assets The Partnership reviews intangible assets and other long-lived assets in accordance with FASB ASC 360-10-05-4 Property Plant and Equipment topic, Impairment or Disposal of Long-Lived Assets subsection, for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. The Partnership determines whether the carrying values of such assets are recoverable over their remaining estimated lives through undiscounted future cash flow analysis. If such a review should indicate that the carrying amount of the assets is not recoverable, the Partnership will reduce the carrying amount of such assets to fair value. Deferred Charges Deferred charges represent the costs associated with the issuance of debt instruments and are amortized over the lives of the related debt instruments. Advertising and Direct Mail Expenses Advertising and direct mail costs are expensed as they are incurred. Advertising and direct mail expenses were $9.5 million, $9.6 million, and $8.4 million, in 2011, 2010, and 2009, respectively and are recorded in delivery and branch expenses. Customer Credit Balances Customer credit balances represent payments received in advance from customers pursuant to a balanced payment plan (whereby customers pay on a fixed monthly basis) and the payments made have exceeded the charges for liquid product and other services. Environmental Costs Costs associated with managing hazardous substances and pollution are expensed on a current basis. Accruals are made for costs associated with the remediation of environmental pollution when it becomes probable that a liability has been incurred and the amount can be reasonably estimated. Insurance Reserves The Partnership uses a combination of insurance, self-insured retention and self-insurance for a number of risks, including workers' compensation, general liability, vehicle liability and property. Reserves are established and periodically evaluated, based upon expectations as to what our ultimate liability may be for outstanding claims using developmental factors based upon historical claim experience, including frequency, severity, demographic factors and other actuarial assumptions, supplemented with support from qualified actuaries. Income Taxes The Partnership is a master limited partnership and is not subject to tax at the entity level for Federal and State income tax purposes. Rather, income and losses of the Partnership are allocated directly to the individual partners (the Partnership's corporate subsidiaries are subject to tax at the entity level for federal and state income tax purposes). While the Partnership will generate non-qualifying Master Limited Partnership revenue through its corporate subsidiaries, distributions from the corporate subsidiaries to the Partnership are generally included in the determination of qualified Master Limited Partnership income. All or a portion of the distributions received by the Partnership from the corporate subsidiaries could be a dividend or capital gain to the partners. The accompanying financial statements are reported on a fiscal year, however, the Partnership and its Corporate subsidiaries file Federal and State income tax returns on a calendar year. As most of the Partnership's income is derived from its corporate subsidiaries, these financial statements reflect significant Federal and State income taxes. For corporate subsidiaries of the Partnership, a consolidated Federal income tax return is filed. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amount of assets and liabilities and their respective tax bases and operating loss carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. A valuation allowance is recognized if, based on the weight of available evidence including historical tax losses, it is more likely than not that some or all of deferred tax assets will not be realized. Sales, Use and Value Added Taxes Taxes are assessed by various governmental authorities on many different types of transactions. Sales reported for product, installation and service excludes taxes. Derivatives and Hedging The Financial Accounting Standards Board ("FASB") ASC 815-10-05 Derivatives and Hedging topic 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. The Partnership has elected not to designate its derivative instruments as hedging instruments under this standard, and the change in fair value of the derivative instruments are recognized in our statement of operations. Weather Hedge Contract Weather hedge contract is recorded in accordance with the intrinsic value method defined by FASB ASC 815-45-15 Derivatives and Hedging topic, Weather Derivatives subtopic (EITF 99-2). The premium paid is amortized over the life of the contract and the intrinsic value method is applied at each interim period. Recent Accounting Pronouncements In May 2011, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. generally accepted accounting principles ("U.S. GAAP") and the International Financial Reporting Standards ("IFRS"), that results in a consistent definition of fair value and common requirements for measurement of and disclosure about fair value. The new guidance clarifies and changes some fair value measurement principles and disclosure requirements under U.S. GAAP. Among them is the clarification that the concepts of highest and best use and valuation premise in a fair value measurement, should only be applied when measuring the fair value of nonfinancial assets. Additionally, the new guidance requires quantitative information about unobservable inputs, disclosure of the valuation processes used and narrative descriptions with regard to fair value measurements within the Level 3 categorization of the fair value hierarchy. The new guidance is effective for interim and annual reporting periods beginning after December 15, 2011, with early adoption prohibited. The adoption of this new guidance is not expected to have a material impact on the Partnership's Consolidated Financial Statements. In June 2011, the FASB issued ASU No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income, and subsequently issued a proposal to defer the requirement to separately present within net income reclassification adjustments of items out of accumulated other comprehensive income. This standard eliminates the option to present items of other comprehensive income ("OCI") as part of the statement of changes in stockholders' equity, and instead requires either OCI presentation and net income in a single continuous statement to the statement of operations, or as a separate statement of comprehensive income. ASU No. 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011, with early adoption permitted. The Partnership is required to adopt this update in the first quarter of fiscal year 2013. The adoption of ASU No. 2011-05 will not impact our results of operations or the amount of assets and liabilities reported. In September 2011, the FASB issued ASU No. 2011-08, Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment. This standard simplifies how entities test goodwill for impairment by providing for an optional qualitative assessment in determining whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, as a basis for determining whether it is necessary to perform the first step, of the two-step goodwill impairment test. The new guidance is effective for annual and interim goodwill impairment tests performed in fiscal years beginning after December 15, 2011, with early adoption permitted. The Partnership has not early adopted this standard and is required to adopt this update in fiscal year 2012. The adoption of ASU No. 2011-08 will not impact our results of operations or the amount of assets and liabilities reported. In September 2011, the FASB issued ASU No. 2011-09, Compensation—Retirement Benefits—Multiemployer Plans (Subtopic 715-80): Disclosures about an Employer's Participation in a Multiemployer Plan. This standard requires employers that participate in multiemployer pension plans to provide additional quantitative and qualitative disclosures such as significant multiemployer plan names, identifying number, employer contributions, an indication of the plan's funded status, and the nature of the employer commitments to the plan. The new guidance is effective for annual periods for fiscal years ending after December 15, 2011, with early adoption permitted. The Partnership has not early adopted this standard and is required to adopt it in fiscal year 2012. The adoption of ASU No. 2011-09 will not impact our results of operations or the amount of assets and liabilities reported.
