Summary of Significant Accounting Policies (Policies) | 12 Months Ended
--- | ---
Sep. 30, 2014
Basis of Presentation | 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.
Correction of Errors | Correction of Immaterial Errors As reported in our June 30, 2014 Form 10-Q, during fiscal year 2014 we recorded adjustments that reduce net income by $2.2 million ($3.7 million, excluding the related income tax benefit) to correct certain errors related to periods from 2002 through September 30, 2013. The errors include understatements of expenses for state sales and petroleum taxes and the related interest and penalties, and overstatements of installations and services sales. The errors were the result of certain control deficiencies that we identified during the third quarter of fiscal 2014. These errors did not, individually or in the aggregate, result in a material misstatement of our previously issued consolidated financial statements for any period through September 30, 2013. The correction of these errors in fiscal year 2014 had no material effect on our results for the full year ending September 30, 2014.
Interest expense, net | Interest expense, net The components of interest expense, net are:
(in thousands) |  | September 30, |
|  | 2014 |  |  | 2013 |  |  | 2012 |
Interest expense |  | $ | (16,904 | ) |  | $ | (14,474 | ) |  | $ | (14,110 | )

Interest expense, net |  | $ | (16,854 | ) |  | $ | (14,433 | ) |  | $ | (14,060 | )
Comprehensive Income | Comprehensive Income Comprehensive income is comprised of net income and other comprehensive income. Other comprehensive income 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.
Use of Estimates | 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 | Revenue Recognition Sales of petroleum products are recognized at the time of delivery to the customer and sales of heating and air conditioning equipment are recognized at the time of installation. Revenue from repairs, maintenance and other services are 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 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 Services Cost of installations and services 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 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, weather hedge contract costs and recoveries, and operational support.
General and Administrative Expenses | 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.
Receivables and Allowance for Doubtful Accounts | Receivables and Allowance for Doubtful Accounts Accounts receivables from customers are recorded at the invoiced amounts. Finance charges may be applied to trade receivables that are more than 30 days past due, and are recorded as finance charge income. The allowance for doubtful accounts 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 by grouping accounts based on certain account criteria 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 | 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 | Net Income per Limited Partner Unit Income per limited partner unit is computed in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 260-10-05 Earnings Per Share, Master Limited Partnerships (EITF 03-06), by dividing the limited partners’ interest in net income by the weighted average number of limited partner units outstanding. The pro forma nature of the allocation required by this standard provides that in any accounting period where the Partnership’s aggregate net income exceeds its aggregate distribution for such period, the Partnership is required to present net income per limited partner unit as if all of the earnings for the periods were distributed, regardless of whether those earnings would actually be distributed during a particular period from an economic or practical perspective. This allocation does not impact the Partnership’s overall net income or other financial results. However, for periods in which the Partnership’s aggregate net income exceeds its aggregate distributions for such period, it will have the impact of reducing the earnings per limited partner unit, as the calculation according to this standard 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.
Cash, Accounts Receivable, Notes Receivable, Revolving Credit Facility Borrowings, and Accounts Payable | 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 | 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 | 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 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 Goodwill and intangible assets include goodwill, customer lists, trade names 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, 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 finite 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 | 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 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 | 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, 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 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 Expenses Advertising and direct mail costs are expensed as they are incurred. Advertising and direct mail expenses were $12.5 million, $10.5 million, and $9.6 million, in 2014, 2013, and 2012, respectively and are recorded in delivery and branch expenses.
Customer Credit Balances | 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 | 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 | 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 | 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 | Sales, Use and Value Added Taxes Taxes are assessed by various governmental authorities on many different types of transactions. Sales reported for product, installations and services excludes taxes.
Derivatives and Hedging | Derivatives and Hedging FASB ASC 815-10-05 Derivatives and Hedging, requires 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 guidance, and the changes in fair value of the derivative instruments are recognized in our statement of operations.
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 FASB 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 2015, 2016 and 2017 the Partnership has a weather hedge contract with subsidiaries of Swiss Re under which we are entitled to receive a payment of $35,000 per heating degree-day shortfall, when the total number of heating degree-days in the hedge period is less than approximately 92.5% of the ten year average, the Payment Threshold. The hedge covers the period from November 1, through March 31, taken as a whole, for each respective fiscal year, and has a maximum payout of $12.5 million for each respective fiscal year.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. This ASU will replace most existing revenue recognition guidance in U.S. Generally Accepted Accounting Principles (“GAAP”) when it becomes effective. This new guidance is effective for our annual reporting period beginning in the first quarter of fiscal 2018, with early adoption prohibited. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a transition method nor has it determined the effect of the standard on its ongoing financial reporting.
