Organization Consolidation And Presentation Of Financial Statements [Abstract]
BASIS OF PRESENTATION	NOTE 1 – BASIS OF PRESENTATION The accompanying condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual consolidated financial statements prepared in accordance with generally accepted accounting principles have been condensed or omitted pursuant to such rules and regulations. However, the Company believes the disclosures included in the accompanying condensed consolidated financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments necessary for a fair presentation for the periods presented have been reflected and are of a normal recurring nature. These condensed consolidated financial statements should be read in conjunction with the Stericycle, Inc. and Subsidiaries Consolidated Financial Statements and notes thereto for the year ended December 31, 2015, as filed with our Annual Report on Form 10-K for the year ended December 31, 2015. The results of operations for the nine months ended September 30, 2016 are not necessarily indicative of the results that may be achieved for the entire year ending December 31, 2016. There were no material changes in the Company’s significant accounting policies since the filing of its 2015 Form 10-K. As discussed in the 2015 Form 10-K, the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States requires management to make certain estimates and assumptions that affect the amount of reported assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and expenses during the periods reported. Actual results may differ from those estimates. Certain amounts in previously issued financial statements have been reclassified to conform to the current period presentation. We have evaluated subsequent events through the date of filing this quarterly report on Form 10-Q. No events have occurred that would require adjustment to or disclosure in the condensed consolidated financial statements.

ACQUISITIONS	NOTE 2 – ACQUISITIONS The following table summarizes the locations of our acquisitions for the nine months ended September 30, 2016: Acquisition Locations 2016 United States 16 Republic of Korea 1 Romania 2 Spain 2 United Kingdom 1 Total 22 During the quarter ended March 31, 2016, we completed seven acquisitions. Domestically, we acquired 100% of the stock of one regulated waste business and selected assets of four secure information destruction businesses. Internationally, we acquired selected assets of one regulated waste business in Romania and one in Spain. During the quarter ended June 30, 2016, we completed ten acquisitions. Domestically, we acquired selected assets of three regulated waste businesses and three secure information destruction businesses. Internationally, we acquired selected assets of one regulated waste business in each of the Republic of Korea, Romania, Spain and the United Kingdom. During the quarter ended September 30, 2016, we completed five domestic acquisitions, acquiring selected assets of one communication services business and four secure information destruction businesses. The following table summarizes the acquisition date fair value of consideration transferred for acquisitions completed during the nine months ended September 30, 2016: In thousands Nine Months Ended September 30, 2016 Cash $ 41,052 Promissory notes 31,063 Deferred consideration 2,045 Contingent consideration 75 Total purchase price $ 74,235 For financial reporting purposes, our acquisitions were accounted for using the acquisition method of accounting. These acquisitions resulted in the recognition of goodwill in our financial statements reflecting the premium paid to acquire businesses that we believe are complementary to our existing operations and fit our growth strategy. During the nine months ended September 30, 2016, we recognized an increase in goodwill of $40.3 million related to current year acquisitions, excluding the effect of foreign currency translation, of which $33.0 million was assigned to our Domestic Regulated Waste and Compliance Services (“Domestic RCS”) reportable segment, $4.4 million was assigned to our International Regulated Waste and Compliance Services (“International RCS”) reportable segment, and $2.9 million was assigned to other (see Note 9 – Goodwill and Other Intangible Assets). Approximately $35.4 million of the goodwill recognized from current year acquisitions will be deductible for tax purposes. During the nine months ended September 30, 2016, we recognized an increase in intangible assets from current year acquisitions of $23.2 million, excluding the effect of foreign currency translation. We recognized $22.4 million for the estimated fair value of acquired customer relationships with amortizable lives of 10 to 40 years, and $0.8 million for a covenant not-to-compete with an amortizable life of 5 years. The fair value of consideration transferred in business combinations is allocated to the tangible and intangible assets acquired and liabilities assumed at the acquisition date, with the remaining unallocated amount recorded as goodwill. The allocations of the acquisition price for recent acquisitions have been prepared on a preliminary basis, pending completion of certain intangible asset valuations and finalization of the opening balance sheet. The following table summarizes the preliminary purchase price allocation for current period acquisitions during the nine months ended September 30, 2016: In thousands Nine Months Ended September 30, 2016 Fixed assets $ 10,487 Intangibles 23,235 Goodwill 40,336 Accounts receivable 1,574 Net other assets/ (liabilities) 8 Current liabilities (355 ) Net deferred tax liabilities (1,050 ) Total purchase price allocation $ 74,235 During the nine months ended September 30, 2016 and 2015 the Company incurred $7.9 million and $40.0 million, respectively, of acquisition related expenses. These expenses are included in “Selling, general and administrative expenses” (“SG&A”) on our Condensed Consolidated Statements of Income. The results of operations of these acquired businesses have been included in the Condensed Consolidated Statements of Income from the date of the acquisition. Pro forma results of operations for these acquisitions are not presented because the pro forma effects, individually or in the aggregate, were not material to the Company’s consolidated results of operations.

We do not anticipate material changes in the purchase price allocation of other prior year acquisitions. Following is a description of the methodologies for estimating the fair value of major tangible and identifiable intangible assets of the Company. Intangible Asset Valuation: The methods commonly used to value intangible assets are the income, market and cost approaches. The nature and characteristics of the asset indicate which approach is most appropriate. Based on the analysis performed by the Company, the fair values of intangible assets were estimated using acceptable income approaches. Following is a description of the methodologies for estimating the fair value of major intangible asset classes: Customer Relationships: A multi-period excess earnings method (“MPEEM”) was used to determine the fair value of the customer relationships. The fair value was derived by calculating the present value of the estimated after-tax earnings attributable to the respective intangible assets. Key inputs and assumptions to the valuation model are forecasted after-tax cash-flows, the identification of contributory assets and the quantification of appropriate returns on these assets, the discount rate applied to present value the cash-flows and attrition rates. Brand: A relief from royalty method was used to determine the fair value of the brand. Key inputs and assumptions to the valuation model are a reasonable approximation of the license rate for the brand, forecasted revenues and the discount rate applied to present value the after-tax stream of estimated royalties avoided by acquiring the brand. Tangible Asset Valuation: Shred trucks, consoles and equipment are some of the major asset classes of fixed assets that were subject to revaluation as of October 1, 2015. The indirect and direct methods of the cost approach and the market approach were used by the Company to value the tangible personal property assets. Following is a description of the methodologies for estimating the fair value of major tangible fixed asset classes: Shred Trucks: The market approach was used for the valuation of the shred trucks. The market approach is based on market conditions and transactions. In the market approach, the assets being valued are compared to recent sales and/or asking prices of comparable properties or assets. In using similar units of comparison, adjustments are made to the comparable assets to account for factors such as condition, capacity, and age. Consoles: The direct method of the cost approach was used in the valuation of the consoles. In the direct method of the cost approach, replacement cost new (RCN) is determined through current cost information obtained from original equipment manufacturers, equipment dealers and vendors, and independent research. Equipment: The cost of reproduction new (CRN) of equipment was calculated using the indirect method of the cost approach. Historical equipment costs and dates were used to calculate the current CRN. In the indirect method of the cost approach, trend factors are applied to the historical costs to estimate the CRN of the assets. Time-adjusted trend factors are applied to historical costs using asset category specific cost indices published by industry sources. The CRN is then adjusted for physical deterioration and functional and economic obsolescence.

Accounting Standards Issued But Not Yet Adopted Revenue From Contracts With Customers In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), guidance to provide a single and 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 amended authoritative guidance associated with revenue recognition is effective for the Company on January 1, 2018. The amended guidance may be applied retrospectively for all periods presented or retrospectively with the cumulative effect of initially applying the amended guidance recognized at the date of initial application. We have engaged a third party to assist the Company in the transition to the new revenue recognition guidance. Currently we are evaluating our existing contracts with customers under the new guidance to determine any impact to our financial statements. We have not yet determined our transition method or whether the adoption will have a material impact on our financial statements.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 4 – FAIR VALUE MEASUREMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (1) market participant assumptions developed based on market data obtained from independent sources (observable inputs) and (2) an entity's own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: Level 1 – Quoted prices in active markets for identical assets or liabilities. Level 2 – Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 – Inputs that are generally unobservable and typically reflect management’s judgment about the assumptions that market participants would use in pricing the asset or liability. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of assets and liabilities and their placement within the fair value hierarchy levels. The impact of creditworthiness and nonperformance risk has been considered in the fair value measurements presented below. There were no movements of items between fair value hierarchies.

We recorded a $0.8 million asset related to the fair value of the U.S. dollar - Canadian dollar foreign currency swap which was classified as other assets at September 30, 2016. The objective of the swap is to offset the foreign exchange risk to the U.S. dollar equivalent cash outflows for our Canadian subsidiary. We had contingent consideration liabilities recorded using Level 3 inputs in the amount of $22.7 million, of which $8.2 million was classified as current liabilities at September 30, 2016. Contingent consideration liabilities were $25.4 million at December 31, 2015 of which $9.1 million was classified as current liabilities. Contingent consideration represents amounts expected to be paid as part of acquisition consideration only if certain future events occur. These events are usually targets for revenues or earnings related to the business acquired. We arrive at the fair value of contingent consideration by applying a weighted probability of potential payment outcomes. The calculation of these potential outcomes is dependent on both past financial performance and management assumptions about future performance. If the financial performance measures were all fully met, our maximum liability would be $39.7 million at September 30, 2016. Contingent consideration liabilities are reassessed each quarter and are reflected in the Condensed Consolidated Balance Sheets as part of “Other current liabilities” and “Other liabilities”. Changes to contingent consideration are reflected in the table below: In thousands Contingent consideration at January 1, 2016 $ 25,390 Increases due to acquisitions 75 Decrease due to payments (2,272 ) Changes due to foreign currency fluctuations 1,560 Changes in fair value reflected in selling, general, and administrative expenses (2,085 ) Contingent consideration at September 30, 2016 $ 22,668 Fair Value of Debt : At September 30, 2016, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $2.98 billion compare to a carrying amount of $3.02 billion. At December 31, 2015, the fair value of the Company’s debt obligations was estimated, using Level 2 inputs, at $3.22 billion compared to a carrying amount of $3.21 billion. The fair values were estimated using an income approach by applying market interest rates for comparable instruments. The Company has no current plans to retire a significant amount of its debt prior to maturity.

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 5 – INCOME TAXES We file income tax returns in the U.S, in various states and in certain foreign jurisdictions. The Company has recorded accruals to cover certain uncertain tax positions. Such uncertain tax positions relate to additional taxes that the Company may be required to pay in various tax jurisdictions. During the course of examinations by various taxing authorities, proposed adjustments may be asserted. The Company evaluates such items on a case-by-case basis and adjusts the accrual for uncertain tax positions as deemed necessary. During the quarter ended September 30, 2016, we had no material changes to our accruals related to previous or current uncertain tax positions. The effective tax rates for the quarters ended September 30, 2016 and 2015 (as restated) were approximately 36.6% and 36.2%, respectively. The higher rate in the current quarter compared to the prior year is primarily related to the recognition of tax benefits in the previous year as well as a higher proportion of pre-tax income in the United States, compared to international operations, which has a higher statutory tax rate.

The following table provides information about our repurchases of depository shares of Mandatory Convertible Preferred Stock during the nine months ended September 30, 2016: Number of Depository Shares Repurchased Amount Paid for Repurchases Average Price Paid per Share (in thousands) Three months ended March 31, 2016 — $ - $ - Three months ended June 30, 2016 65,000 5,025 77.31 Three months ended September 30, 2016 265,000 19,238 72.60 Nine months ended September 30, 2016 330,000 $ 24,263 $ 73.52 Repurchases of our Mandatory Convertible Preferred Stock resulted in a $6.5 million and $7.7 million gain for the three and nine months ended September 30, 2016, respectively, because we redeemed the preferred stock at a discount. The 330,000 depository shares are equivalent to 33,000 units of preferred stock. Series A Mandatory Convertible Preferred Stock Offering: On September 15, 2015, we completed a registered public offering of 7,700,000 depositary shares, each representing a 1/10th interest in a share of our 5.25% Series A Mandatory Convertible Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”), at a public offering price of $100.00 per depository share for total gross proceeds of $770.0 million. Unless earlier converted or redeemed, each share of the Series A Preferred Stock will automatically convert into between 5.8716 and 7.3394 shares of our common stock, subject to anti-dilution and other adjustments, on the mandatory conversion date, which is expected to be September 15, 2018. The number of shares of our common stock issuable on conversion will be determined based on the volume-weighted average price of our common stock over the 20 trading day period commencing on and including the 23rd scheduled trading day prior to September 15, 2018. Subject to certain restrictions, at any time prior to September 15, 2018, holders of the Series A Preferred Stock may elect to convert all or a portion of their shares into common stock at the minimum conversion rate of 5.8716 shares of common stock per share of Series A Preferred Stock, subject to adjustment. Dividends on shares of the Series A Preferred Stock are payable on a cumulative basis when, as and if declared by our board of directors, or an authorized committee thereof, at an annual rate of 5.25% on the liquidation preference of $1,000 per share (and, correspondingly, $100.00 per share with respect to the depositary shares). The dividends may be payable in cash, or subject to certain limitations, in shares of our common stock or any combination of cash and shares of our common stock on March 15, June 15, September 15 and December 15 of each year, commencing on December 15, 2015, and to, and including, September 15, 2018. We declared and paid dividends of $9.7 million and $29.9 million to the preferred stock shareholders for the three and nine months ended September 30, 2016, respectively.

EARNINGS PER COMMON SHARE

Earnings Per Share [Abstract]
EARNINGS PER COMMON SHARE	NOTE 8 – EARNINGS PER COMMON SHARE Basic earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing income available to common shareholders by the weighted-average number of shares of common stock outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the potentially dilutive securities had been issued. Potentially dilutive securities include outstanding stock options, shares to be purchased under the Company’s employee stock purchase plan, RSUs, and the assumed conversion of mandatory convertible preferred stock. The effect of potentially dilutive securities is reflected in diluted earnings per share by application of the “treasury stock method” for outstanding restricted stock awards and stock options. Under the treasury stock method, an increase in the fair market value of the Company’s common stock can result in a greater dilutive effect from potentially dilutive securities. For the issue of the mandatory convertible preferred stock, we use the “if-converted method”. Under the if-converted method, the preferred dividend applicable to convertible preferred stock is added back as an adjustment to the numerator. The Mandatory Convertible Preferred shares are assumed to be converted to common shares at the beginning of the period or, if later, at the time of issuance, and the resulting common shares are included in the denominator. In applying the if-converted method, conversion shall not be assumed for purposes of computing diluted EPS if the effect would be anti-dilutive. The numerator is also adjusted for any premium or discount arising from redemption of the preferred stock. The following table sets forth the computation of basic and diluted earnings per share: In thousands, except share and per share data Three Months Ended September 30, Nine Months Ended September 30, 2016 2015 (Restated) 2016 2015 (Restated) Numerator: Net income attributable to Stericycle, Inc. $ 64,795 $ 69,449 $ 187,615 $ 186,219 Less: mandatory convertible preferred stock dividend 9,726 — 29,853 — Less: gain on repurchase of preferred stock (6,467 ) — (7,747 ) — Numerator for basic earnings per share attributable to Stericycle, Inc. common shareholders $ 61,536 $ 69,449 $ 165,509 $ 186,219 Denominator: Denominator for basic earnings per share-weighted average shares 85,044,303 84,884,599 84,881,452 84,960,955 Effect of diluted securities: Employee stock based awards 526,226 1,235,716 808,073 1,273,904 Mandatory convertible preferred stock (1) — — — — Denominator for diluted earnings per share-adjusted weighted average shares and after assumed exercises 85,570,529 86,120,315 85,689,525 86,234,859 Earnings per share – Basic $ 0.72 $ 0.82 $ 1.95 $ 2.19 Earnings per share – Diluted $ 0.72 $ 0.81 $ 1.93 $ 2.16 (1) The weighted average common shares issuable upon the assumed conversion of the mandatory convertible preferred stock totaling 5,495,861 and 5,590,105 shares for the three and nine months ended September 30, 2016 For additional information regarding outstanding employee stock options, see Note 6 - Stock Based Compensation.

Goodwill And Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	NOTE 9 – GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill and other identifiable indefinite lived intangibles are not amortized, but are subject to an annual impairment test, or more frequent testing if circumstances indicate that they may be impaired. Goodwill: During the second quarter of 2016, we changed the composition of our operating segments; see Note 12 – Segment Reporting for more information. Due to this change, part of our Domestic Regulated Waste and Compliance Services operating segment was combined with the legacy Domestic Regulated Recall and Returns Management Services operating segment to form a new operating segment, Domestic Communication and Related Services. Our three operating segments, which are also our reporting units, are: • Domestic Regulated Waste and Compliance Services, • Domestic Communication and Related Services, and • International Regulated Waste and Compliance Services. Our Domestic Communication and Related Services operating segment does not meet the quantitative criteria to be a separate reportable segment and is categorized as “Other.” Goodwill was reassigned to the affected reporting units using a relative fair value approach. That is, the goodwill was assigned to the businesses in the Domestic Regulated Waste and Compliance Services reporting unit based on their relative fair values and then the assigned goodwill followed the business impacted by the reorganization into the new Domestic Communication and Related Services reporting unit. As a result of these changes in our segment reporting, all historical segment information has been revised to conform to the new presentation including our goodwill rollforward by segment. The changes in the carrying amount of goodwill since January 1, 2015, by reportable segment and for the "Other” category, were as follows: In thousands Domestic Regulated Waste and Compliance Services International Regulated Waste and Compliance Services Other Total Balance as of January 1, 2015 $ 1,467,969 $ 614,783 $ 336,080 $ 2,418,832 Goodwill acquired during the year 1,150,437 273,519 26,994 1,450,950 Purchase accounting allocation adjustments for prior year acquisitions (6,221 ) (19,072 ) (2,984 ) (28,277 ) Goodwill other changes — (440 ) — (440 ) Changes due to foreign currency fluctuations — (82,888 ) — (82,888 ) Balance as of December 31, 2015 2,612,185 785,902 360,090 3,758,177 Goodwill acquired during the year 33,041 4,422 2,873 40,336 Purchase accounting allocation adjustments for prior year acquisitions (74,193 ) (103,398 ) (2,663 ) (180,254 ) Changes due to foreign currency fluctuations — (21,360 ) — (21,360 ) Balance at September 30, 2016 $ 2,571,033 $ 665,566 $ 360,300 $ 3,596,899 Current year adjustments to goodwill are primarily due to updated tangible and intangible asset valuations for certain 2015 acquisitions. During the quarter ended June 30, 2016, we performed our annual goodwill impairment evaluation for our three reporting units: Domestic Regulated Waste and Compliance Services, Domestic Communication and Related Services, and International Regulated Waste and Compliance Services. We calculated the fair value of each of our reporting units using an income method and validated those results using a market approach by applying estimated EBITDA multiples to the EBITDA of the reporting units. The income approach uses expected future cash flows of each reporting unit and discounts those cash flows to present values. Expected future cash flows are calculated using management assumptions of growth rates, capital expenditures, and cost efficiencies. Future acquisitions are not included in the expected future cash flows. We use a discount rate based on our Company calculated weighted average cost of capital which is adjusted for each of our reporting units based on size and country risk premiums. The results of our goodwill impairment test using the market approach corroborated the results of the impairment test under the income approach and indicated the fair value of our reporting units exceeded their respective carrying values. Due to the change in reporting units during the second quarter, we analyzed goodwill for impairment immediately before and after we reorganized our reporting structure. As a result of this analysis, we concluded that goodwill related to the effected reporting units were not impaired. Other Intangible Assets: At September 30, 2016 and December 31, 2015, the values of other intangible assets were as follows: In thousands September 30, 2016 December 31, 2015 Gross Carrying Amount Accumulated Amortization Net Value Gross Carrying Amount Accumulated Amortization Net Value Amortizable intangibles: Customer relationships $ 1,579,988 $ 241,368 $ 1,338,620 $ 1,304,388 $ 144,020 $ 1,160,368 Covenants not-to-compete 10,561 6,501 4,060 6,878 5,141 1,737 Tradenames 9,088 1,797 7,291 3,819 948 2,871 Other 19,005 2,924 16,081 18,902 916 17,986 Indefinite lived intangibles: Operating permits 242,281 — 242,281 233,101 — 233,101 Tradenames 318,776 — 318,776 426,498 — 426,498 Total $ 2,179,699 $ 252,590 $ 1,927,109 $ 1,993,586 $ 151,025 $ 1,842,561 The changes in the carrying amount of intangible assets since January 1, 2015 were as follows: In thousands Total Balance as of January 1, 2015 $ 909,645 Intangible assets acquired during the year 1,016,775 Valuation adjustments for prior year acquisitions 35,241 Impairments during the year (4,177 ) Amortization during the year (45,498 ) Changes due to foreign currency fluctuations (69,425 ) Balance as of December 31, 2015 1,842,561 Intangible assets acquired during the year 23,235 Valuation adjustments for prior year acquisitions 178,621 Impairments during the year (4 ) Amortization during the year (102,311 ) Changes due to foreign currency fluctuations (14,993 ) Balance at September 30, 2016 $ 1,927,109 Under generally accepted accounting principles, a fair value must be assigned to all acquired assets based on a theoretical “market participant” regardless of the acquirer's intended use for those assets. This accounting treatment can lead to the recognition of losses when a company disposes of acquired assets. We complete our annual impairment analysis of our indefinite lived intangibles during the quarter ended December 31 of each year, or more frequently, if circumstances indicate that they may be impaired. Our finite-lived intangible assets are amortized over their useful lives. We have determined that our customer relationships have useful lives from 5 to 40 years based upon the type of customer, with a weighted average remaining useful life of 15.3 years. We have covenant not-to-compete intangibles with useful lives from 5 to 14 years, with a weighted average remaining useful life of 3.5 years. We have tradename intangibles with useful lives from 10 to 40 years, with a weighted average remaining useful life of 15.0 years. Other intangibles mainly consist of landfill air rights with a weighted average remaining useful life of 18.0 years. We have determined that our permits have indefinite lives due to our ability to renew these permits with minimal additional cost, and therefore these are not amortized. We also have a trade name that we have determined has an indefinite life. During the quarters ended September 30, 2016 and 2015, the aggregate amortization expense was $33.1 million and $9.2 million, respectively. We recorded approximately $33 million of additional amortization during the nine months ended September 30, 2016 due to an update to the valuation of the Shred-it intangibles. For the nine months ended September 30, 2016 and 2015, the aggregate amortization expense was $102.3 million and $27.0 million, respectively. The estimated amortization expense for each of the next five years, assuming no additional amortizable intangible assets, is as follows for the years ended December 31: In thousands 2016 $ 132,122 2017 118,850 2018 118,788 2019 117,964 2020 116,353 Future amortization expense may fluctuate depending on changes in foreign currency rates, future acquisitions, or changes to the estimated amortizable life of the intangibles. The estimates for amortization expense noted above are based upon foreign exchange rates as of September 30, 2016.

Environmental Remediation Obligations [Abstract]
ENVIRONMENTAL REMEDIATION LIABILITIES	NOTE 10 – 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. The liability for environmental remediation is included in the Condensed Consolidated Balance Sheets in current liabilities within “Accrued liabilities” and in non-current liabilities within “Other liabilities.” At September 30, 2016, the total environmental remediation liabilities recorded were $30.5 million, of which $2.7 million was classified as accrued liabilities and $27.8 million was classified as other liabilities.

The financial debt covenants are the same for the senior credit facility, term loan, and the private placement notes. At September 30, 2016, we were in compliance with all of our financial debt covenants. Our senior credit facility, term loan, and the private placement notes rank pari passu to each other and all other unsecured debt obligations.

Segment Reporting [Abstract]
SEGMENT REPORTING	NOTE 12 – SEGMENT REPORTING Our plans to make certain changes to our organizational structure to integrate the domestic and international Shred-it operations into our Domestic Regulated Waste and Compliance Services and International Regulated Waste and Compliance Services operating segments, respectively, were finalized in the second quarter of 2016. We also changed the composition of our operating segments to further align our compliance and communication services. Due to this change, part of our Domestic Regulated Waste and Compliance Services operating segment was combined with the legacy Domestic Regulated Recall and Returns Management Services operating segment to form a new operating segment, Domestic Communication and Related Services. As a result, our three operating segments are: • Domestic Regulated Waste and Compliance Services; • Domestic Communication and Related Services; and • International Regulated Waste and Compliance Services. Our Domestic and International Regulated Waste and Compliance segments include medical waste disposal, pharmaceutical waste disposal, hazardous waste management, sustainability solutions for expired or unused inventory, secure information destruction of documents and e-media, training and consulting through our Steri-Safe® and Clinical Services programs, and other regulatory compliance services. Our Domestic Communication and Related Services segment consists of inbound/outbound communication, automated patient reminders, online scheduling, notifications, product retrievals, product returns, and quality audits. Our two reportable segments are: • Domestic Regulated Waste and Compliance Services (“Domestic RCS”), • International Regulated Waste and Compliance Services (“International RCS”). Our Domestic Communication and Related Services operating segment does not meet the quantitative criteria to be a separate reportable segment and is categorized as “Other.” In connection with changes made to our management reporting to align with the new operating segments, we have also changed our measure of segment profit a measure of earnings before interest, tax and amortization (“EBITA”). As a result of these changes in segment reporting, all historical segment information has been revised to conform to the new presentation.

Commitments And Contingencies Disclosure [Abstract]
LEGAL PROCEEDINGS	NOTE 13 – LEGAL PROCEEDINGS We operate in a highly regulated industry and must deal with regulatory inquiries or investigations from time to time that may be instituted for a variety of reasons. We are also involved in a variety of civil litigation from time to time. We review all of our outstanding legal proceedings with counsel quarterly, and we will disclose an estimate of any reasonably possible loss or range of reasonably possible losses if and when we are able to make such an estimate and the reasonably possible loss or range of reasonably possible losses is material to our financial statements. Contract Class Action Lawsuits. As we have previously disclosed, we were served on March 12, 2013 with a class action complaint filed in the U.S. District Court for the Western District of Pennsylvania by an individual plaintiff for itself and on behalf of all other “similarly situated” customers of ours. The complaint alleges, among other things, that we imposed unauthorized or excessive price increases and other charges on our customers in breach of our contracts and in violation of the Illinois Consumer Fraud and Deceptive Business Practices Act. The complaint sought certification of the lawsuit as a class action and the award to class members of appropriate damages and injunctive relief. The Pennsylvania class action complaint was filed in the wake of a settlement with the State of New York of an investigation under the New York False Claims Act which arose out of the qui tam (or “whistle blower”) action captioned United States of America ex rel. Jennifer D. Perez v. Stericycle, Inc., Case No. 1:08-cv-2390 which was settled in the fourth quarter of 2015 as previously disclosed. Following the filing of the Pennsylvania class action complaint, we were served with class action complaints filed in federal and state courts in several jurisdictions. These complaints asserted claims and allegations substantially similar to those made in the Pennsylvania class action complaint. All of these cases appear to be follow-on litigation to our settlement with the State of New York. On August 9, 2013, the Judicial Panel on Multidistrict Litigation granted our Motion to Transfer these related actions to the United States District Court for the Northern District of Illinois for centralized pretrial proceedings (the “MDL Action”). On December 10, 2013, we filed our answer to the Amended Consolidated Class Action Complaint in the MDL Action, generally denying the allegations therein. Plaintiffs subsequently filed a Second Amended Consolidated Complaint on March 8, 2016, and we filed an answer to that pleading on March 25, 2016, generally denying the allegations therein and asserting a variety of affirmative defenses. The parties are currently briefing plaintiffs’ motion for class certification which was filed on January 29, 2016. We filed our response to that motion as well as a motion to strike plaintiffs’ expert reports on August 29, 2016. On October 27, 2016, plaintiffs filed their reply memorandum in further support of their motion for class certification and their opposition to our motion to exclude plaintiffs’ expert reports. We believe that we have operated in accordance with the terms of our customer contracts and that these complaints are without merit. We will continue to vigorously defend ourselves against each of these lawsuits. We have not accrued any amounts in respect of these class action lawsuits, and we cannot estimate the reasonably possible loss or the range of reasonably possible losses that we may incur. We are unable to make such an estimate because (i) litigation is by its nature uncertain and unpredictable, (ii) we do not know whether the court will certify any class of plaintiffs or, if any class is certified, how the class would be defined, (iii) if a class or classes are certified, what the ultimate disposition on the merits would be of any class claim as well as our defenses to that claim, and (iv) in our judgment, there are no comparable proceedings against other defendants that might provide guidance in making estimates. Securities Class Action Lawsuit. On July 11, 2016, two purported stockholders filed a putative class action complaint in the U.S. District Court for the Northern District of Illinois. The plaintiffs purported to sue for themselves and on behalf of all purchasers of our publicly traded securities between February 7, 2013 and April 28, 2016, inclusive, and all those who purchased securities in our public offering of depositary shares, each representing a 1/10th interest in a share of our mandatory convertible preferred stock, on or around September 15, 2015. The complaint named as defendants the Company, our directors and certain of our current and former officers, and certain of the underwriters in the public offering. The complaint purports to assert claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as well as SEC Rule 10b-5, promulgated thereunder. The complaint alleges, among other things, that the Company imposed unauthorized or excessive price increases and other charges on its customers in breach of its contracts, and that defendants failed to disclose those alleged practices in public filings and other statements issued during the proposed class period beginning February 7, 2013 and ending April 28, 2016. On August 4, 2016, plaintiffs filed an Amended Complaint that purports to assert additional misrepresentations in public statements through July 28, 2016, and therefore to change the putative class period to the period from February 7, 2013 to July 28, 2016, inclusive. On October 21, 2016, plaintiffs filed a Corrected Amended Complaint adding the Company as a named defendant in plaintiff’s Count I, asserting a claim under Section 11 of the Securities Act, which had previously been asserted only against the Underwriters and certain officers and directors. On November 1, 2016, the Court appointed the Public Employees’ Retirement System of Mississippi and the Arkansas Teacher Retirement System as Lead Plaintiffs and their counsel as Lead Counsel and ordered the parties to confer on a schedule going forward. We intend to vigorously defend ourselves against this lawsuit. We have not accrued any amounts in respect of this lawsuit, and we cannot estimate the reasonably possible loss or the range of reasonably possible losses that we may incur. We are unable to make such an estimate because (i) litigation is by its nature uncertain and unpredictable, (ii) we do not know whether the court will certify any class of plaintiffs or, if any class is certified, how the class would be defined, and (iii) in our judgment, there are no comparable proceedings against other defendants that might provide guidance in making estimates. Shareholder Derivative Lawsuit. On September 1, 2016, a purported stockholder filed a putative derivative action complaint in the Circuit Court of Cook County, Illinois against certain officers and directors of the Company, naming the Company as nominal defendant. The complaint alleges that defendants breached their fiduciary duties to the Company and its stockholders by causing the Company to allegedly overcharge certain customers in breach of those customers’ contracts, otherwise provide unsatisfactory customer service and injure customer relationships, and make materially false and misleading statements and omissions regarding the Company’s business, operational and compliance policies between February 7, 2013 and the present. The Company notes, among other things, that this filing is in violation of the Company’s Bylaws, which require any such actions to be brought in a court in Delaware. None of the defendants in the Derivative Action has been served with the Complaint. We have not accrued any amounts in respect of this lawsuit, and we cannot estimate the reasonably possible loss or the range of reasonably possible losses that we may incur. We are unable to make such an estimate because (i) litigation is by its nature uncertain and unpredictable, (ii) we do not know whether the court will certify any class of plaintiffs or, if any class is certified, how the class would be defined, and (iii) in our judgment, there are no comparable proceedings against other defendants that might provide guidance in making estimates. Shareholder Demand Letter. On October 18, 2016, the Company received a letter from an attorney purporting to represent a current stockholder of the Company demanding, pursuant to Del. Ct. Ch. R. 23.1, that the Company’s Board of Directors take action to remedy alleged breaches of fiduciary duties by certain officers and directors of the Company. The factual allegations set forth in the letter are similar to those asserted in the Securities Class Action Lawsuit and the Shareholder Derivative Lawsuit. The letter asserts breaches of fiduciary duty in connection with the management, operation and oversight of the Company’s business and in connection with alleged false, misleading and/or incomplete statements regarding the Company’s business practices. The Company has responded to advise that the demand letter has been communicated to the Board of Directors for consideration. TCPA Lawsuit. On June 3, 2016, plaintiff filed a putative class action, captioned Ibrahim v. Stericycle, Inc., No. 16-cv-4294 (N.D. Ill.), against us and our wholly-owned subsidiary, Stericycle Communication Solutions, Inc., under the Telephone Consumer Protection Act (“TCPA”), asserting that the defendants called plaintiff and others in violation of that statute. Plaintiff challenges our use of pre-recorded messages that urge the owners of recalled products to return or obtain repairs for those products. Plaintiff seeks certification of two nationwide classes. One class includes people who received one or more cellular telephone calls from Stericycle featuring a prerecorded or artificial voice message relating to a product recall, where the called party was not the same individual who, according to Stericycle’s records, was the intended recipient of the call. The second class includes people who received one or more cellular telephone calls from Stericycle featuring a prerecorded or artificial voice message relating to a product recall after such person had communicated to Stericycle that Stericycle did not have consent to make any such calls to their cellular telephone number. On July 28, 2016, we answered the complaint, denying the material allegations and raising certain affirmative defenses. Among the asserted defenses is the “emergency” exception to the TCPA, which exempts calls made to promote public health and safety. We have not accrued any amounts in respect of this lawsuit, and we cannot estimate the reasonably possible loss or the range of reasonably possible losses that we may incur. We are unable to make such an estimate because (i) litigation is by its nature uncertain and unpredictable, (ii) we do not know whether the court will certify any class of plaintiffs or, if any class is certified, how the class would be defined, and (iii) in our judgment, there are no comparable proceedings against other defendants that might provide guidance in making estimates. Environmental Matters. Our Environmental Solutions business is regulated by federal, state and local laws enacted to regulate the discharge of materials into the environment, remediate contaminated soil and groundwater or otherwise protect the environment. As a result of this continuing regulation, we frequently become a party to legal or administrative proceedings involving various governmental authorities and other interested parties. The issues involved in these proceedings generally relate to alleged violations of existing permits and licenses or alleged responsibility under federal or state Superfund laws to remediate contamination at properties owned either by us or by other parties to which either we or the prior owners of certain of its facilities shipped wastes. From time to time, we may be subject to fines or penalties in regulatory proceedings relating primarily to waste treatment, storage or disposal facilities. We believe that the fines or other penalties that we may pay in connection with any pending regulatory proceedings of this nature will not, individually or in the aggregate, be material to our financial statements. On February 29, 2016, we entered into a statute of limitations tolling agreement with the United States Attorney’s Office for the District of Utah relating to that Office’s investigation of the same facts underlying the notice of violation (the “NOV”) issued by the State of Utah Division of Air Quality (the “DAQ”) that resulted in our December 2014 settlement with the DAQ that we have previously disclosed. The U.S. Attorney’s Office is investigating whether the matters forming the basis of the NOV constitute violations of the Clean Air Act and other federal statutes. On October 7, 2016, we extended the tolling agreement to February 28, 2017. Under the tolling agreement as extended, the period from March 1, 2016 through February 28, 2017 will be excluded from any calculation of time for the purpose of determining the statute of limitations concerning any charges that we violated federal statutes. The agreement does not constitute an admission of guilt or wrongdoing on our part and cannot be construed as a waiver of any other rights or defenses that we may have in any resulting action or proceeding. We will continue to cooperate with the investigation. On April 8, 2016, the State of Missouri through the Missouri Department of Natural Resources (“MDNR”) filed an Amended Verified Petition in the Circuit Court of the City of St. Louis, Missouri alleging that we had violated certain provisions of the Solid Waste Permit relating to our facility located in St. Louis by failing to treat or transport certain waste within 24 hours or to transfer certain waste within 24 hours. The Petition also alleged that certain record keeping requirements had not been met. On May 27, 2016 a First Amended Verified Petition was filed with essentially the same allegations. MDNR originally filed its Petition on October 16, 2014. On October 31, 2016, we entered into a Consent Judgment that requires us to timely treat or transfer waste received, to keep proper records and to pay a civil penalty of $130,000.

Accounting Standards Issued But Not Yet Adopted Revenue From Contracts With Customers In May 2014, the FASB issued ASU No. 2014-09, "Revenue from Contracts with Customers" (Topic 606), guidance to provide a single and 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 amended authoritative guidance associated with revenue recognition is effective for the Company on January 1, 2018. The amended guidance may be applied retrospectively for all periods presented or retrospectively with the cumulative effect of initially applying the amended guidance recognized at the date of initial application. We have engaged a third party to assist the Company in the transition to the new revenue recognition guidance. Currently we are evaluating our existing contracts with customers under the new guidance to determine any impact to our financial statements. We have not yet determined our transition method or whether the adoption will have a material impact on our financial statements. Leases In February 2016, the FASB issued ASU No. 2016-02, “Leases” (Topic 842) Statement of Cash Flows In August 2016, the FASB issued ASU No. 2016-15 “ Statement of Cash Flows” (Topic 230)
