| Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles ("GAAP") requires the use of certain estimates by management in determining the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions are the allowance for doubtful accounts receivable, valuation of inventory at lower of cost or market, valuation of goodwill and other intangible assets, share-based compensation, and income taxes. Actual results could differ from those estimates. Revenue Recognition The Company derives its revenues primarily from the services it performs and from the sale of processed oil from its used oil re-refinery. Parts cleaning and other service revenues are recognized as the service is performed. Product revenues are recognized at the time risk of loss passes to the customer. The risk of loss passes to customers at various times depending on the particular terms of the sales agreement in force with each individual customer. Common thresholds for when risk of loss passes to the customer are at the time that product is loaded onto the shipping vessel or at the time that product is offloaded at the customer’s receiving location. Revenues are recognized only if collection of the relevant receivable is probable, persuasive evidence of an arrangement exists, and the sales price is fixed or determinable. Sales Tax Amounts billed for sales tax, value added tax, or other transactional taxes imposed on revenue producing transactions are presented on a net basis and are not recognized as revenues. Operating Costs Within operating costs are cost of sales. Cost of sales in the Environmental Services segment includes the cost of the materials the Company sells and provides in its services, such as solvents and other chemicals, transportation of inventory and waste, and payments to third parties to recycle or dispose of the waste materials that the Company collects. Parts cleaning machines are either sold to a customer or continue to be owned by the Company but placed offsite at a customer location to be used in parts cleaning services. When sold to a customer, machines are removed from inventory, and the costs are recognized under operating costs. The used solvent that the Company retrieves from customers in its product reuse program is accounted for as a reduction in net cost of solvent under cost of sales, whether placed in inventory or sold to a purchaser for reuse. If the used solvent is placed in inventory it is recorded at lower of cost or net realizable value. Cost of sales in the Oil Business include the costs paid to customers for used oil (if any), transportation out to customers, and costs to operate the used oil re-refinery, including utilities. Operating costs also include the Company's costs of operating its branch system and hubs. These costs include personnel costs, facility rent and utilities, truck leases, fuel, transportation, and maintenance. Operating costs are not presented separately for products and services. Selling, General, and Administrative Expenses Selling, general, and administrative expenses include costs of performing centralized business functions, including sales management at or above the regional level, billing, receivables management, accounting and finance, information technology, environmental health and safety, and legal. Cash and Cash Equivalents The Company considers highly liquid investments, purchased with an original maturity of ninety days or less, to be cash equivalents. Included in cash and cash equivalents are $0.5 million and $0.2 million of cash on deposit outside the United States of America as of December 30, 2017 and December 31, 2016, respectively. Concentration Risk Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution in the United States of America are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. The Company had cash deposits in excess of the FDIC insured limit of $41.1 million and $35.9 million at December 30, 2017 and December 31, 2016, respectively. The Company has not experienced any losses in such accounts. The Company has a broad customer base and believes it is not exposed to any significant concentration of credit risk. Accounts Receivable Trade accounts receivable represent amounts due from customers. The allowance for doubtful accounts is the Company's best estimate of the amount of probable credit losses in the Company's existing accounts receivable. The Company determines the allowance based on analysis of customer credit worthiness, historical losses, and general economic trends and conditions. Accounts receivable are written off once the Company determines the account to be uncollectible. The Company does not have any off-balance-sheet credit exposure related to its customers. Inventory Inventory consists primarily of used oil, processed oil, catalyst, new and used solvents, new and refurbished parts cleaning machines, new and used antifreeze products, drums, and other items. Inventories are valued at the lower of first-in, first-out ("FIFO") cost or market, net of any reserves for excess, obsolete, or unsalable inventory. The Company performs a physical inventory count on a periodic basis and uses the results of these counts to determine inventory quantities. These quantities are used to help determine the value of the inventory. Processed oil inventory consists of the costs of feedstock, transportation, labor, conversion costs, and re-refining overhead costs incurred in bringing the inventory to its existing condition and location. Fixed production overhead costs are capitalized in processed oil inventory based on the normal capacity of the production facility. In periods of abnormal production levels, excess overhead costs are recognized as expense in the period they are incurred. The Company continually monitors its inventory levels at each of its distribution locations and evaluates inventories for excess or slow-moving items. If circumstances indicate the cost of inventories exceed their recoverable value, inventories are reduced to net realizable value. In fiscal 2017 the Company did no t incur inventory write-downs. In fiscal 2016, the Company wrote down inventory by $1.7 million due to sharply declining prices of oil and other petroleum-based products. Prepaid and Other Current Assets Prepaid and other current assets include, but are not limited to, insurance and vehicle license contract costs, which are expensed over the term of the underlying contract. Property, Plant, and Equipment Property, plant, and equipment are stated at cost. Expenditures for major renewals and betterments are capitalized, while expenditures for repair and maintenance charges are expensed as incurred. Property, plant, and equipment acquired in business combinations is stated at fair value as of the date of the acquisition. Depreciation of property, plant, and equipment is calculated using the straight-line method over the estimated useful lives of the assets. The estimated useful lives of buildings and storage tanks range from 10 to 39 years. The estimated useful lives of machinery, vehicles, and equipment range from 3 to 25 years. Leasehold improvements are amortized over the shorter of the lease terms or five years using the straight-line method. The Company capitalizes interest on borrowings during the active construction period of major capital projects. Capitalized interest is added to the cost of the underlying assets and is amortized over the useful lives of the assets once the assets are placed into service. The interest rate used to capitalize interest is based upon the borrowing rate on the Company's bank debt outstanding. In fiscal 2017 the Company capitalized no interest for capital projects, and in fiscal 2016 and 2015, the Company capitalized interest of $0.1 million , and $0.6 million , respectively. Equipment at Customers The Company records purchases of new parts cleaning machines as inventory. Parts cleaning machines are either sold to a customer or continue to be owned by the Company but placed off-site at a customer location to be used in parts cleaning services. When sold to a customer, machines are removed from inventory, and the appropriate revenues and costs are recognized in the Income Statement. When the Company retains title to a machine that is placed off-site at a customer location to be used in parts cleaning services, the Company capitalizes the machine as a productive non-current asset under the Balance Sheet caption “Equipment at Customers” at the time the machine is placed at the customer’s site. Machines capitalized as Equipment at Customers are depreciated over their estimated useful lives of 7 to 15 years, depending on the model. Depreciation of in-service equipment commences when equipment is placed in service at a customer location. Expenditures for machines that are sold to a customer are treated as a cash outflow from operating activities on the Statement of Cash Flows. Expenditures for machines that are placed at a customer’s site to be used in parts cleaning services are treated as a cash outflow from investing activities. Acquisitions The Company accounts for acquired businesses using the purchase method of accounting, which requires that the assets acquired, liabilities assumed, and contingent consideration be recorded as of the date of acquisition at their respective fair values. It further requires that acquisition-related costs be recognized separately from the acquisition and expensed as incurred and that restructuring costs be expensed in periods subsequent to the acquisition date. In many cases, the Company engages third party valuation appraisal firms to assist the Company in determining the fair values and useful lives of the assets acquired and liabilities assumed. The Company records a preliminary purchase price allocation for its acquisitions and finalizes purchase price allocations as additional information relative to the fair values of the assets acquired becomes known. Identifiable Intangible Assets The fair value of identifiable intangible assets is based on significant judgments made by management. The Company engaged third party valuation appraisal firms to assist the Company in determining the fair values and useful lives of the assets acquired. Such valuations and useful life determinations require the Company to make significant estimates and assumptions. These estimates and assumptions are based on historical experience and information obtained from the management of the acquired companies and include, but are not limited to, future expected cash flows to be earned from the continued operation of the acquired business and discount rates applied in determining the present value of those cash flows. Unanticipated events and circumstances may occur that could affect the accuracy or validity of such assumptions, estimates, or actual results. Acquisition-related finite lived intangible assets are amortized on a straight-line basis over their estimated economic lives. The Company evaluates the estimated benefit periods and recoverability of its intangible assets when facts and circumstances indicate that the lives may not be appropriate and/or the carrying value of the asset may not be recoverable. If the carrying value is not recoverable, impairment is measured as the amount by which the carrying value exceeds its estimated fair value. There were no impairment charges in fiscal 2017. Software Costs The Company expenses costs incurred in the research stage of developing or acquiring internal use software, such as research and feasibility studies, as well as costs incurred in the post-implementation/operational stage, such as maintenance and training. Capitalization of software costs occurs only after the research stage is complete and after the development stage begins. The capitalized costs are amortized on a straight-line basis over the estimated useful lives of the software, ranging from 5 to 10 years. Impairment of Long-Lived Assets Long-lived assets, such as property and equipment and intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized as the amount by which the carrying amount of the asset exceeds the fair value of the asset. There were no impairment charges in fiscal 2017. Assets to be disposed of would be separately presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell, and would no longer be depreciated. Income Taxes The Company accounts for income taxes to recognize the amount of taxes payable or refundable for the current year and the amount of deferred tax assets and liabilities resulting from the future tax consequences of differences between the financial statements and tax basis of the respective assets and liabilities. The Company estimates and reserves for any material uncertain tax position that is unlikely to withstand an audit by the taxing authorities. These estimates are based on judgments made with currently available information. The Company reviews these estimates and makes changes to recorded amounts of any uncertain tax positions as facts and circumstances warrant. For additional information about income taxes, see Note 14. Shipping Costs For all periods presented, amounts billed to customers related to shipping and handling are classified as revenue, and the Company's shipping and handling costs are included in operating costs. Research and Development Research and development costs are expensed as incurred within general, selling, and administrative expenses. Such costs incurred during fiscal 2017, 2016 and 2015 were $0.5 million , $0.2 million , and $0.2 million , respectively. Advertising Costs Advertising costs are expensed as incurred. Advertising expense was $0.5 million , $0.5 million , and $0.6 million for fiscal 2017, 2016, and 2015, respectively. Share-Based Compensation When a future restricted grant is approved, the Company evaluates the probability that the award will be granted, based on certain performance conditions. If satisfaction of the performance criteria is deemed probable, the Company accrues compensation expense related to these awards prior to the grant date. The Company accrues compensation expense based on the fair value of the performance awards at each reporting period when the performance criteria are deemed probable. Once the performance awards have been granted, the Company values the awards at fair value on the date of grant and amortizes the expense through the end of the vesting period, or requisite service period, on a straight-line basis. The requisite service period is a function of the service condition defined for each award on a case by case basis. See Note 15 “Share-Based Compensation” for more details. Fair Value of Financial Instruments The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include: Level 1, defined as quoted market prices in active markets for identical assets or liabilities; Level 2, defined as inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, model-based valuation techniques for which all significant assumptions are observable in the market, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and Level 3, defined as unobservable inputs that are not corroborated by market data. The Company’s financial instruments consist primarily of cash and cash equivalents, trade receivables, trade payables, notes payable, and term debt. As of December 30, 2017 and December 31, 2016 , the carrying values of cash and cash equivalents, trade receivables, trade payables, and notes payable are considered to be representative of their respective fair values due to the short maturity of these instruments. Term debt is representative of its fair value due to the interest rates being applied. Insurance and Self-Insurance Policy The Company purchases insurance providing financial protection from a range of risks; as of the end of fiscal 2017, the Company's insurance policies provided coverage for general liability, vehicle liability, and pollution liability, among other exposures. Each of these policies contains exclusions and limitations such that they would not cover all related exposures and each of these policies have maximum coverage limits and deductibles such that even in the event of an insured claim, the Company's net exposure could still have a material adverse effect on its financial results. The Company is self-insured for certain healthcare benefits provided to its employees. The liability for the self-insured benefits is limited by the purchase of stop-loss insurance. The stop-loss coverage provides payment for medical and prescription claims exceeding $200,000 per covered person, as well as an aggregate, cumulative claims cap for any given year. Accruals for losses are made based on the Company's claim experience and actuarial estimates based on historical data. Actual losses may differ from accrued amounts. At December 30, 2017 and December 31, 2016 , the Company's liability for its self-insured benefits was $1.3 million and $1.2 million , respectively. Should actual losses exceed the amounts expected and the recorded liabilities be insufficient, additional expense will be recorded. Expenses incurred for healthcare benefits in fiscal 2017, 2016, and 2015 were $11.9 million , $11.6 million , and $11.6 million , respectively. Goodwill Goodwill is measured as a residual amount as of the acquisition date, which in most cases results in measuring goodwill as an excess of the purchase consideration transferred plus the fair value of any noncontrolling interest in the acquiree over the fair value of the net assets acquired, including any contingent consideration. The Company tests goodwill for impairment annually in the fourth quarter and in interim periods if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company's determination of fair value requires certain assumptions and estimates, such as margin expectations, market conditions, growth expectations, expected changes in working capital, etc., regarding expected future profitability and expected future cash flows. The Company tests goodwill for impairment at each of its two reporting units, Environmental Services and Oil Business. In fiscal 2015, we tested goodwill for impairment. In fiscal 2015, the fair value of the Environmental Services reporting unit was substantially in excess of its carrying value. In fiscal 2015, our tests indicated impairment of all of the goodwill in our Oil Business reporting unit. Therefore during the fourth quarter of fiscal 2015 we recorded a charge of approximately $4.0 million related to impairment of goodwill in our Oil Business reporting unit. The facts and circumstances leading to the impairment were primarily related to the deterioration of market conditions in the markets in which the Company’s Oil Business reporting unit operates. The deterioration of those market conditions manifested in lower average selling prices for the Company’s re-refined lubricating base oil, recycled fuel oil, and byproducts within the Oil Business. The method for determining the fair value of the Oil Business reporting unit was a combination of an income approach using a discounted cash flow method in combination with a market approach using a guideline company method. There was a moderate degree of uncertainty associated with key Oil Business fair value assumptions such as the selling prices of our oil products and byproducts, the price paid or charged for raw material inputs such as used oil, operating efficiency of the used oil re-refinery, etc. A contraction of the spread between the selling prices of our oil products and the price paid or charged to vendors for raw material inputs could reasonably be expected to negatively affect the key assumptions used to determine fair value. In fiscal 2016, we tested goodwill for impairment. The Oil Business reporting unit had zero goodwill throughout fiscal 2016. The fair value of the Environmental Services reporting unit was substantially in excess of its carrying amount including goodwill, and therefore no impairment was indicated. In fiscal 2017, the Company performed a qualitative assessment to determine whether the two-step quantitative impairment test was necessary. The Oil Business reporting unit had zero goodwill throughout fiscal 2017. Based on the qualitative assessment, the Company concluded it is more likely than not that the fair value of the Environmental Services reporting unit is greater than its carrying amount including goodwill, and therefore the two-step quantitative test was not necessary and no impairment was indicated. Recently Issued Accounting Pronouncements Accounting standards not yet adopted Standard Issuance Date Description Our Effective Date Effect on the Financial Statements ASU 2014-09 “Revenue from Contracts with Customers (Topic 606),” ASU 2014-15 “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” ASU 2016-08 “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” ASU 2016-10 “ Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” and ASU 2016-12 “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients” May 2014 and subsequent These standards outline a single comprehensive model for entities to use in accounting for revenue using a five-step process that supersedes virtually all existing revenue guidance. The underlying principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Entities have the option of using either a full retrospective approach or a modified retrospective approach to adopt the guidance. Early adoption is permitted. December 31, 2017 The Company analyzed the impact of the standard on our contracts by reviewing our current accounting policies and practices to identify potential differences that would result from applying the requirements of the new standard to our revenue contracts. In addition, we have identified appropriate changes to our business processes, systems, and controls to support recognition and disclosure under the new standard. The Company will adopt the new revenue guidance effective December 31, 2017, using the modified retrospective transition method, by recognizing the cumulative effect of initially applying the new standard as a decrease to the opening balance of retained earnings. We expect this adjustment to be less than $1 million, with an immaterial impact to our revenues and net income on an ongoing basis. The impact to our results is not material because, for the vast majority of our revenue, the analysis of our contracts under the new revenue recognition standard supports the recognition of revenue which is consistent with our current revenue recognition model. With the adoption of the standard, the consolidated financial statements will be supplemented by new disclosure requirements. ASU 2016-02 February 2016 This update was issued to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. Early application of the amendments in this update is permitted for all entities. January 4, 2019 The Company is currently evaluating the effect that implementation of this update will have on its consolidated financial position and results of operations. The Company anticipates that implementation of this standard will result in an increase to assets and an increase to liabilities. To date, certain personnel have attended technical training concerning this new lease accounting standard. Recently issued accounting standards adopted Standard Issuance Date Description Effective Date Effect on the Financial Statements ASU 2016-09 Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting. (Topic 718) March 2016 This update addresses the simplification of accounting for employee share-based payment transactions as it pertains to income taxes, the classification of awards as equity or liabilities, accounting for forfeitures, statutory tax withholding requirements, and certain classifications on the statement of cash flows. Early adoption is permitted. January 1, 2017 ASU 2016-09 simplified the treatment for employee share-based compensation by allowing an entity to recognize excess tax benefits in the current period whether or not current taxes payable are reduced. Prior to 2017 the Company could not recognize windfall tax benefits associated with employee share-based compensation because it was in an NOL position and current taxes payable would not be reduced by the excess tax benefits. As a result of ASU 2016-09 the Company recognized excess tax benefits of $2.5 million from share-based compensation from prior years, resulting in cumulative-effect increases to retained earnings and deferred tax assets of approximately $1.0 million. In conjunction with the adoption of ASU 2016-09, the Company reclassified $131 thousand of cash outflows for share repurchases to satisfy tax withholding obligations from Cash flows from Operating Activities to Cash flows from Financing Activities compared to the amounts previously reported for the fiscal year ended January 2, 2016. ASU 2015-11, Simplifying the Measurement of Inventory. (Topic 330) July 2015 This update requires the measurement of inventory at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. January 1, 2017 The adoption of ASU 2015-11 at the start of fiscal 2017 resulted in no impact to our consolidated financial statements. ASU 2014-15 Presentation of Financial Statements - Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. (Subtopic 205-40) August 2014 This update provides guidance about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote disclosures. Early adoption is permitted. December 31, 2016 The adoption of ASU 2014-15 in fiscal 2016 resulted in no impact to our consolidated financial statements. ASU 2015-03 April 2015 These updates require debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt, and allows for the presentation of debt issuance costs as an asset regardless of whether or not there is an outstanding balance on the line-of-credit arrangement. January 3, 2016 The adoption of ASU 2015-03 resulted in the reclassification of $1.4 million of unamortized debt issuance costs from "Other current assets" to "Term loan, less current maturities" as of January 2, 2016. ASU 2015-16 Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments (Topic 805) September 2015 This update simplifies the accounting for measurement-period adjustments in a business combination by requiring the acquirer to recognize adjustments to provisional amounts identified during the measurement period in the reporting period in which the adjustments are determined. The acquirer is also required to record in the reporting period in which the adjustments are determined the effect on earnings of changes in depreciation, amortization, and other items resulting from the change to the provisional amounts. January 3, 2016 The Company early adopted the amendments of this ASU No. 2015-16 in fiscal 2015 and it did not have an impact on our consolidated financial condition and results of operations. |
