SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation:

The consolidated financial statements include the accounts of Stericycle, Inc. and its subsidiaries.

Revenue Recognition:

Revenues for our regulated waste management services, other than our compliances services such as Steri-Safe, are recognized at the time of waste collection. Our compliance service revenues are recognized evenly over the contractual service period. Payments received in advance are deferred and recognized as services are provided. Revenues from hazardous waste services are recorded at the time waste is received at our processing facility. Revenues from regulated recall and returns management services and communication solutions are recorded at the time services are performed. Revenues from product sales are recognized at the time the goods are shipped to the ordering customer. Charges related to international value added tax ("VAT") and other similar pass through taxes are not included as revenue.

Cash Equivalents and Short-Term Investments:

We consider all highly liquid investments with a maturity of less than three months when purchased to be cash equivalents. Short-term investments consist of certificates of deposit which mature in less than one year.

Property, Plant and Equipment:

Property, plant and equipment are stated at cost. Depreciation and amortization, which include the depreciation of assets recorded under capital leases, are computed using the straight-line method over the estimated useful lives of the assets as follows:



Building and improvements		5 to 50 years
Machinery and equipment		3 to 30 years
Containers		2 to 20 years
Vehicles		2 to 7 years
Office equipment and furniture		2 to 15 years
Software		2 to 7 years

Our containers have a weighted average remaining useful life of 13.1 years.

Acquisition Accounting:

Acquisition accounting requires us to recognize assets and liabilities at their fair value. The process of determining fair value requires time to complete therefore we will make some estimates at the time of acquisition. These estimates are primarily for amortizable intangibles and, if appropriate, an associated deferred tax liability. These estimates are based on historical experience and allow us to recognize amortization expense until the final valuation is complete.

Goodwill and Identifiable Intangibles:

Goodwill and identifiable indefinite lived intangible assets are not amortized, but are subject to an annual impairment test (see Note 11 - Goodwill and Other Intangible Assets for more information about goodwill and the annual impairment test). Our finite-lived intangible assets are amortized over their useful lives. We have determined that our customer relationships have useful lives from 10 to 40 years based upon the type of customer, with a weighted average remaining useful life of 23.8 years. We have covenants not-to-compete intangibles with useful lives from 3 to 14 years, with a weighted average remaining useful life of 4.7 years. We have tradename intangibles with useful lives from 10 to 40 years, with a weighted average remaining useful life of 15.8 years. We have technology with useful life of 5 years, with a weighted average remaining useful life of 1.0 years. We have determined that our permits have indefinite lives due to our ability to renew these permits with minimal additional cost, and therefore they are not amortized. We also have a tradename that we have determined has an indefinite life.

Our indefinite lived intangible assets are tested for impairment annually at December 31, or more frequently, if circumstances indicate that they may be impaired. We use a qualitative assessment, as provided for under the FASB Accounting Standards Codification Topic 350, Intangibles - Goodwill and Other, to determine if is is more likely then not that the asset is impaired. If there is an indication of impairment, we test the recoverability of the asset using either a discounted income or cost savings model to calculate fair value. The calculated fair value is based upon, among other things, certain assumptions about expected future operating performance, internal and external processing costs, and an appropriate discount rate determined by management. Our estimates of discounted income may differ from actual income due to, among other things, inaccuracies in economic estimates (see Note 11 - Goodwill and Other Intangible Assets for more information about indefinite lived intangible assets).

Valuation of Intangibles:

Valuation of our intangible assets other than goodwill is derived using a discounted income and cost savings approach. Financial information such as revenues, costs, assets and liabilities, and other assumptions related to the intangible asset are input into a standard valuation model to determine a stream of income attributable to that intangible. The income stream is then discounted to the present to arrive at a valuation. We perform annual impairment tests on our indefinite lived intangible assets.

We have determined that our customer relationships have lives between 10 and 40 year based on the specific type of relationship. The valuation of our contractual customer relationships was derived using a discounted income approach valuation model. These assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may be less than its undiscounted estimated future cash flows (see Note 11 - Goodwill and Other Intangible Assets for more information about our intangible assets other than goodwill).

Share Repurchases:

Purchase price over par value for share repurchases are allocated to retained earnings.

Income Taxes:

Deferred income tax assets and liabilities are determined based on the differences between the financial statement and income tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Interest and penalties accrued related to unrecognized tax benefits are recognized as a component of income tax expense.

Accounts Receivable:

Accounts receivable consist of amounts due to us from our normal business activities and are carried at their estimated collectible amounts. Our accounts receivable balance includes amounts related to VAT and similar international pass-through taxes. We do not require collateral as part of our standard trade credit policy. Accounts receivable balances are determined to be past due when the amount is overdue based on the contractual terms with the customer. We maintain an allowance for doubtful accounts to reflect the expected uncollectibility of accounts receivable based on past collection history and specific risks identified among uncollected accounts. Accounts receivable are written off against the allowance for doubtful accounts when we have determined that the receivable will not be collected and/or when the account has been referred to a third party collection agency. No single customer accounts for more than approximately 1% of our accounts receivable. Bad debt expense was $9.9 million, $4.8 million and $4.6 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Environmental Remediation Liabilities:

We record a liability for environmental remediation when such liability becomes probable and the costs or damages can be reasonably estimated. We accrue environmental remediation costs, on an undiscounted basis, associated with identified sites where an assessment has indicated that cleanup costs are probable and can be reasonably estimated, but the timing of such payments is not fixed and determinable. Such accruals are based on currently available information, estimated timing of remedial actions, existing technology, and enacted laws and regulations.

Financial Instruments:

Our financial instruments consist of cash and cash equivalents, short-term investments, accounts receivable and payable and long-term debt. At December 31, 2014, the fair value of the Company’s debt obligations was estimated at $1.67 billion, compared to a carrying amount of $1.66 billion. This fair value was estimated using market interest rates for comparable instruments. The Company has no current plans to retire a significant amount of its debt prior to maturity. Financial instruments, which potentially subject us to concentrations of credit risk, consist principally of accounts receivable. Credit risk on trade receivables is minimized as a result of the large size of our customer base. No single customer represents greater than approximately 1% of total accounts receivable. We perform ongoing credit evaluation of our customers and maintain allowances for potential credit losses. For any contracts in loss positions, losses are recorded when probable and estimable. These losses, when incurred, have been within the range of our expectations.

Use of Estimates:

The preparation of financial statements in conformity with generally accepted accounting principles requires us to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Some areas where we make estimates include allowance for doubtful accounts, credit memo reserve, accrued employee health and welfare benefits, stock compensation expense, income tax liabilities, accrued auto and workers’ compensation insurance claims, and intangible asset valuations. Such estimates are based on historical trends and on various other assumptions that are believed to be reasonable under the circumstances. Actual results could differ from our estimates.

Future estimated expenses may fluctuate depending on changes in foreign currency rates. The estimates for payments due on long-term debt, lease payments under capital leases, accrued liabilities, contingent consideration liabilities, intangible assets amortization expense, and rental payments are based upon foreign exchange rates at December 31, 2014.

Stock-Based Compensation:

We recognize compensation expense for all stock-based awards made to our employees and directors. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized over the vesting period. Determining the fair value of stock-based awards at the grant date requires considerable judgment, including estimating expected volatility of our stock, expected term of the award, and the risk-free interest rate. Our stock’s expected volatility is based upon historical experience. The expected term of options granted is based on historical experience. The risk-free interest rate assumption is based upon the U.S. Treasury yield rates for a comparable period. If factors change and we employ different assumptions, stock-based compensation expense for new grants may differ significantly from what we have recorded in the past.

Foreign Currency Translation:

Assets and liabilities of foreign affiliates that use the local currency as their functional currency are translated at the exchange rate on the last day of the accounting period, and income statement accounts are translated at the average rates during the period. Related translation adjustments are reported as a component of accumulated other comprehensive loss in Stericycle, Inc.'s equity.

New Accounting Standards:

Accounting Standards Recently Adopted

Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists

On January 1, 2014, we adopted guidance on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. An unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except in certain circumstances. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. For example, an entity should not evaluate whether the deferred tax asset expires before the statute of limitations on the tax position or whether the deferred tax asset may be used prior to the unrecognized tax benefit being settled. We are applying this guidance on a prospective basis. The implementation of this guidance did not affect our results of operations or financial liquidity.

Accounting Standards Issued But Not Yet Adopted

Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity

In April 2014, the Financial Accounting Standards Board ("FASB") issued guidance that changes the threshold for reporting discontinued operations and adds new disclosures. The new guidance defines a discontinued operation as a disposal of a component or group of components that is disposed of or is classified as held for sale and "represents a strategic shift that has (or will have) a major effect on an entity's operations and financial results." For disposals of individually significant components that do not qualify as discontinued operations, an entity must disclose pre-tax earnings of the disposed component. For public business entities, this guidance is effective prospectively for all disposals (or classifications as held for sale) of components of an entity that occur within annual periods beginning on or after December 15, 2014, and interim periods within those years. Early adoption is permitted, but only for disposals (or classifications as held for sale) that have not been reported in financial statements previously issued or available for issuance. The Company has no plans to dispose of a component of our entity and therefore does not expect the adoption of this guidance to have a material impact on the Company’s financial position or results of operations.

Revenue From Contracts With Customers

In May 2014, the FASB issued guidance to provide a single, comprehensive revenue recognition model for all contracts with customers. The revenue guidance contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. The standard will be effective for the first interim period within annual reporting periods beginning after December 15, 2016 for public entities, with no early adoption permitted. The Company is currently evaluating the impact of the adoption of this guidance on its internal processes, operating results, and financial reporting. The impact is currently not known or reasonably estimable.

Accounting for Share-Based Payment When the Terms of an Award Provide That a Performance Target Could Be Achieved After the Requisite Service Period

In June 2014, the FASB issued guidance that applies to all reporting entities that grant their employees share-based payments in which the terms of the award provide that a performance target that affects vesting could be achieved after the requisite service period. It requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition and follows existing accounting guidance for the treatment of performance conditions. The standard will be effective for annual periods and interim periods within those annual periods beginning after December 15, 2015, with early adoption permitted. The Company does not have any share-based payments with a performance target and therefore does not expect the adoption of this guidance to have a material impact on the Company’s financial position or results of operations.
