Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited consolidated financial statements have been prepared in accordance with (i) United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and (ii) the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, such financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments that are necessary for the fair statement of the interim periods presented. Interim results of operations are not necessarily indicative of the results for the full year. The Financial Statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) in our Annual Report on Form 10-K for the fiscal year ended October 31, 2015 (“Annual Report”). Unless otherwise noted, all references to years are to our fiscal year, which ends on October 31 . Rounding We round amounts in the Financial Statements to millions and calculate all percentages and per-share data from the underlying whole-dollar amounts. As a result, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding. Adoption of New Accounting Pronouncement During the first quarter of 2016, we early adopted Accounting Standards Update (“ASU”) 2015-17, Balance Sheet Classification of Deferred Taxes, on a retrospective basis. As a result, all deferred tax assets and liabilities are now classified as noncurrent on our consolidated balance sheets. Prior Year Reclassifications (in millions) Previously Reported October 31, 2015 Adjustment Revised October 31, 2015 Deferred income tax asset, net (current) $ 53.2 $ (53.2 ) $ — Deferred income tax liability, net (noncurrent) $ 19.1 $ (19.1 ) $ — Deferred income tax asset, net (noncurrent) $ — $ 34.1 $ 34.1 In addition, we reclassified prior year amounts throughout the Financial Statements to conform to the current year presentation of discontinued operations. See Note 4 , “Discontinued Operations,” for more information. Parking Revenue Presentation Our Parking business operates certain parking facilities under managed location arrangements. Under these arrangements, we manage the parking facility for a management fee and pass through the revenue and expenses associated with the facility to the owner. These revenues and expenses are reported in equal amounts for costs reimbursed from our managed locations.

Restructuring and Related Activities [Abstract]
Restructuring and Related Costs	RESTRUCTURING AND RELATED COSTS On September 2, 2015, our Board of Directors approved a comprehensive strategy intended to have a positive transformative effect on ABM (the “2020 Vision”). As part of the 2020 Vision, we identified a number of key priorities to differentiate ABM in the marketplace, improve our margin profile, and accelerate revenue growth. We also reviewed all service lines and investments to assess whether ABM was positioned to continue to competitively offer value-added services to clients over the long term. Reconciliation of Restructuring and Related Cost Accrual (in millions) External Support Fees Employee Severance Lease Exit and Other Total Balance, November 1, 2015 $ 2.1 $ 4.3 $ 0.2 $ 6.6 Costs recognized – first quarter (1)(2) 4.6 1.8 0.8 7.2 Costs recognized – second quarter (1)(2) 4.5 3.7 0.6 8.8 Payments (7.6 ) (3.8 ) (1.0 ) (12.4 ) Balance, April 30, 2016 $ 3.6 $ 6.0 $ 0.6 $ 10.3 (1) From inception of our 2020 Vision in the fourth quarter of 2015, we have incurred cumulative restructuring and related charges of $28.7 million , consisting of external support fees of $13.7 million , employee severance costs of $10.3 million , asset impairment costs of $2.6 million , and lease exit and other costs of $2.2 million . (2) The results by segment exclude these costs, consistent with the manner in which our management evaluates the performance of each reportable segment based on its respective operating profit results. These costs are included within Corporate expenses. See Note 15 , “Segment Information,” for more information.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On October 26, 2015, in connection with our 2020 Vision, we sold substantially all of the assets of our Security business to Universal Protection Service, LP (“UPS”) for cash proceeds of $131.0 million , subject to a working capital adjustment. In the second quarter of 2016, the working capital adjustment related to the sale was finalized, resulting in a payment to UPS of $3.1 million . As such, we reduced the gain on sale recorded in the fourth quarter of 2015 by the amount of this adjustment.

In addition, certain general corporate expenses that were previously allocated to Security are now allocated back to Corporate expenses and the Janitorial segment. Refer to Note 15 , “Segment Information,” for further information. (2) Discontinued operations includes both costs related to ongoing legal cases and insurance reserves associated with our former Security business. We will continue to reflect these types of costs within discontinued operations in future periods. Refer to Note 12 , “Commitments and Contingencies,” and Note 10 , “Insurance,” for further information. (3) For the six months ended April 30, 2016, the income tax benefit includes the retroactive reinstatement of the Work Opportunity Tax Credits (“WOTC”). (4) During the first quarter of 2016, we paid $20.6 million in taxes in connection with the sale of our Security business.

Acquisitions

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS 2016 Acquisitions Effective December 1, 2015, we acquired all of the outstanding stock of Westway Services Holdings (2014) Ltd. (“Westway”), a provider of technical engineering services to customers in the United Kingdom, for a purchase price of $81.0 million . We accounted for this acquisition under the acquisition method of accounting. Accordingly, we allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values, and recorded the excess of the purchase price as goodwill. As of April 30, 2016, the valuation of the intangible assets was incomplete. As such, the purchase price allocation reflects preliminary amounts of net assets acquired, including other intangible assets. These net assets are subject to adjustments within the measurement period, which is not to exceed one year from the acquisition date. We recorded preliminary goodwill of $45.1 million , which is primarily attributable to projected long-term margin improvement through expansion of our technical services business to new and existing clients in the United Kingdom. Goodwill also reflects our identification of buyer-specific synergies that we anticipate will be realized by the reduction of duplicative positions, back office functions, professional fees, and other services. The goodwill associated with this acquisition is not deductible for tax purposes. As of December 1, 2015, the operations of Westway are included in our Building & Energy Solutions segment. 2015 Acquisitions Effective May 1, 2015, we acquired certain assets and assumed certain liabilities of CTS Services/Facility Support Services (“CTS”), a provider of HVAC services and energy solutions in government, commercial, and industrial buildings, for a purchase price of $18.8 million . The purchase price includes $3.8 million of contingent consideration that is based on the expected achievement of certain pre-established revenue goals. See Note 7 , “Fair Value of Financial Instruments,” regarding the valuation of the contingent consideration liability. As of May 1, 2015, the operations of CTS are included in our Building & Energy Solutions segment. Pro Forma and Other Supplemental Financial Information Pro forma and other supplemental financial information is not presented for these acquisitions, as they are not considered material business combinations.

The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. (2) For investments in auction rate securities, the fair value was based on discounted cash flow valuation models, primarily utilizing unobservable inputs. These amounts are included in “Other investments” on the accompanying unaudited consolidated balance sheets. See Note 9 , “Auction Rate Securities,” for further information. (3) Represents interest rate swap derivatives designated as cash flow hedges. The fair values of the interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for LIBOR forward rates at the end of the period. For 2016 the interest rate swap was included in “Other noncurrent assets,” and for 2015 the interest rate swaps were included in “Other accrued liabilities” on the accompanying unaudited consolidated balance sheets. See Note 11 , “Line of Credit,” for more information. (4) Cash and cash equivalents are stated at nominal value, which equals fair value. (5) Represents restricted insurance deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets. See Note 10 , “Insurance,” for further information. (6) Certain of our acquisitions involve the payment of contingent consideration. Depending on the structure of the contingent consideration arrangement, the fair value of the liability is based on either (i) the expected achievement of certain pre-established revenue goals or (ii) pre-defined forecasted adjusted income from operations using a probability weighted income approach. Our contingent consideration liabilities are included in “Other accrued liabilities” and “Other noncurrent liabilities” on the accompanying unaudited consolidated balance sheets. (7) Represents outstanding borrowings under our syndicated line of credit. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit approximates the fair value. See Note 11 , “Line of Credit,” for further information. Our non-financial assets, which include goodwill and long-lived assets held and used, are not required to be measured at fair value on a recurring basis. However, if certain triggering events occur, or if an annual impairment test is required, we would evaluate the non-financial assets for impairment. If an impairment were to occur, the asset would be recorded at the estimated fair value, which is determined using discounted future cash flows for goodwill or undiscounted future cash flows for long-lived assets. During the six months ended April 30, 2016 , we had no transfers of assets or liabilities between any of the above hierarchy levels.

Auction Rate Securities	AUCTION RATE SECURITIES At October 31, 2015 , we held investments in auction rate securities from three different issuers that had an aggregate original principal amount of $15.0 million and an amortized cost and fair value of $13.0 million . During the second quarter of 2016, one of our auction rate securities was redeemed by the issuer at its par value of $5.0 million . No gain or loss was recognized upon its redemption. At April 30, 2016 , the two remaining auction rate securities had an aggregate original principal amount of $10.0 million and an amortized cost and fair value of $8.0 million . These two auction rate securities are debt instruments with stated maturities in 2036 and 2050 . The interest rates for these securities are designed to be reset through Dutch auctions approximately every thirty days, but auctions for these securities have not occurred since August 2007 . At April 30, 2016 and October 31, 2015 , there were no unrealized gains or losses on our auction rate securities included in accumulated other comprehensive loss, net of taxes (“AOCL”), and the total amount of other-than-temporary impairment credit loss on our auction rate security investments included in our retained earnings was $2.0 million .

Insurance [Abstract]
Insurance	INSURANCE We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. For the majority of these insurance programs, we retain the initial $1.0 million of exposure on a per-occurrence basis, either through deductibles or self-insured retentions. Beyond the retained exposures, we have varying primary policy limits ranging between $1.0 million and $5.0 million per occurrence. To cover general liability and automobile liability losses above these primary limits, we maintain commercial umbrella insurance policies that provide aggregate limits of $200.0 million . Our insurance policies generally cover workers’ compensation losses to the full extent of statutory requirements. Additionally, to cover property damage risks above our retained limits, we maintain policies that provide per occurrence limits of $75.0 million . The adequacy of our reserves for workers’ compensation, general liability, automobile liability, and property damage insurance claims is based upon known trends and events and the actuarial estimates of required reserves considering the most recently completed actuarial reports. We use all available information to develop our best estimate of insurance claims reserves as information is obtained. During the three months ended January 31, 2016, an actuarial review was performed for the majority of our casualty insurance programs that indicated unfavorable developments in our estimates of ultimate losses related to certain general liability, workers’ compensation, and automobile liability claims, as described below. This review considered all changes made to claims reserves and claim payment activity for the period commencing May 1, 2015 and ending October 31, 2015 (the “Review Period”). We performed this review for all policy years in which open claims existed. For our general liability program, claim frequency was generally consistent with our expectations. However, the actuarial review identified adverse developments in prior year claims. The adverse developments can be largely attributed to increases in the projected costs to resolve several high exposure claims within our retained limits. Also contributing to the increase in projected estimates was a higher than expected average incurred cost for our less severe claims observed during the Review Period. Our workers’ compensation estimate of ultimate losses was negatively impacted by increases in projected costs for a significant number of prior year claims in New York. These claims have been impacted by increases in statutory benefits and a slowing of claims closures observed during the Review Period. In California, we experienced increases in severity of claims and in frequency of claims beyond that previously projected. For our automobile liability program, the increase in the projected estimates was primarily associated with significant claim reserve adjustments for a small population of high exposure claims within the 2013 policy year. Also contributing to the increase in projected estimates was an increase in claims frequency in the 2015 policy year observed during the Review Period. As a result of these developments in our casualty insurance programs, we increased our reserves for known claims as well as our estimate of the loss amounts associated with incurred but not reported (“IBNR”) claims. As a result of this actuarial review, we increased our reserves for claims related to prior periods by $6.0 million at January 31, 2016. As we continue to see a similar trend in adverse developments, we increased our reserves by an additional $6.0 million , resulting in a total increase to our reserves for claims related to prior periods of $12.0 million at April 30, 2016. During the third quarter of 2016, we expect to complete comprehensive actuarial evaluations for our significant insurance programs using recent claims data. We will continue to monitor claims developments, which may result in further adjustments to our reserves. We are also self-insured for certain employee medical and dental plans. We retain up to $0.4 million of exposure on a per-participant, per-year basis with respect to claims under our medical plan. At April 30, 2016 and October 31, 2015 , we had insurance claim reserves totaling $394.8 million and $387.4 million , respectively, which include $7.5 million and $8.1 million in reserves, respectively, related to our medical and dental self-insured plans. At April 30, 2016 and October 31, 2015 , we also had insurance recoverables, which we include in “Other current assets” and “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets, totaling $66.0 million and $65.9 million , respectively.

Line of Credit

Debt Disclosure [Abstract]
Line of Credit	LINE OF CREDIT On November 30, 2010 , we entered into a syndicated credit agreement pursuant to which we obtained an unsecured revolving credit facility (the “Facility”). This credit agreement, as amended from time to time, is referred to as the “Credit Agreement.” We can borrow up to $800.0 million under our Credit Agreement and we have the option to increase the size of the Facility to $1.0 billion at any time prior to the December 11, 2018 expiration date (subject to receipt of commitments for the increased amount from existing and new lenders). Borrowings under the Facility bear interest at a rate equal to an applicable margin plus, at our option, either a (i) eurodollar rate (generally LIBOR) or (ii) base rate determined by reference to the highest of (1) the federal funds rate plus 0.50% , (2) the prime rate published by Bank of America, N.A. from time to time, and (3) the eurodollar rate plus 1.00% . The applicable margin is a percentage per annum varying from zero to 0.75% for base rate loans and 1.00% to 1.75% for eurodollar loans, based upon our leverage ratio. We also pay a commitment fee, based on the leverage ratio, payable quarterly in arrears, ranging from 0.200% to 0.275% on the average daily unused portion of the Facility. For purposes of this calculation, irrevocable standby letters of credit, which are issued primarily in conjunction with our insurance programs, and cash borrowings are included as outstanding under the Facility. The Credit Agreement contains certain financial covenants that require us to maintain a maximum leverage ratio of 3.25 to 1.0 at the end of each fiscal quarter (except as described below), a minimum fixed charge coverage ratio of 1.50 to 1.0 at any time, and a consolidated net worth in an amount not less than the sum of (i) $570.0 million , (ii) 50% of our consolidated net income (with no deduction for net loss), and (iii) 100% of our aggregate increases in stockholders’ equity beginning on November 30, 2010 . In the event of a material acquisition, as defined in the Credit Agreement, we may elect to increase the leverage ratio to 3.50 to 1.0 for a total of four fiscal quarters. As of April 30, 2016 , we were in compliance with these covenants. If an event of default occurs under the Credit Agreement, including certain cross-defaults, insolvency, change in control, or violation of specific covenants, the lenders can terminate or suspend our access to the Facility, declare all amounts outstanding under the Facility (including all accrued interest and unpaid fees) to be immediately due and payable, and require that we cash collateralize the outstanding standby letters of credit. The Facility is available for working capital, the issuance of up to $300.0 million for standby letters of credit, the issuance of up to $50.0 million in swing line advances, the financing of capital expenditures, and other general corporate purposes, including acquisitions and investments in subsidiaries, subject to certain limitations, where applicable, as set forth in the Credit Agreement. Facility Information (in millions) April 30, 2016 October 31, 2015 Cash borrowings $ 208.9 $ 158.0 Standby letters of credit 127.6 112.9 Borrowing capacity (1) 463.5 529.1 (1) Availability of our borrowing capacity is subject to, and limited by, compliance with the covenants described above. Interest Rate Swaps We enter into interest rate swaps to manage the interest rate risk associated with our floating-rate, LIBOR-based borrowings under our Facility. Under these arrangements, we typically pay a fixed interest rate in exchange for LIBOR-based variable interest throughout the life of the agreement. During the second quarter of 2016, several interest rate swaps matured that had an underlying aggregate notional amount of $155.0 million . During April and May 2016, we entered into three new interest rate swap agreements with an underlying aggregate notional amount of $105.0 million , a fixed interest rate of 1.05% , and effective dates of April 7, 2016 and May 11, 2016. These swaps were designated and accounted for as cash flow hedges from inception and mature on April 7, 2021 and May 11, 2021. We recognize interest rate swaps on the accompanying unaudited consolidated balance sheets at fair value. The fair value of our interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for LIBOR forward rates at the end of the period. See Note 7 , “Fair Value of Financial Instruments,” for more information. The effective portion of the derivative’s mark-to-market gain or loss is initially reported as a component of AOCL and subsequently reclassified into earnings when the hedged transactions occur and affect earnings. The ineffective portion of the gain or loss is reported in earnings immediately. Interest payables and receivables under the swap agreements are accrued and recorded as adjustments to interest expense. At April 30, 2016 and October 31, 2015 , the net unrealized gains and losses recorded in AOCL were $0.1 million , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Surety Bonds and Letters of Credit We use surety bonds and letters of credit to secure certain commitments related to insurance programs and for other purposes. As of April 30, 2016 , these surety bonds and letters of credit totaled $391.5 million and $127.6 million , respectively. Included in the total amount of surety bonds is $0.7 million of bonds with an effective date starting after April 30, 2016 . Guarantees In some instances, we offer certain clients guaranteed energy savings under certain energy savings contracts. At April 30, 2016 and October 31, 2015 , total guarantees were $96.1 million and $90.5 million , respectively, and these guarantees extend through 2031 and 2030 , respectively. We accrue for the estimated cost of guarantees when it is probable that a liability has been incurred and the amount can be reasonably estimated. Historically, we have not incurred any material losses in connection with these guarantees. In connection with an unconsolidated joint venture in which one of our subsidiaries has a 33% ownership interest, that subsidiary and the other joint venture partners have each jointly and severally guaranteed the obligations of the joint venture to perform under certain contracts extending through 2018. Annual revenues relating to the underlying contracts are approximately $35.0 million . Should the joint venture be unable to perform under these contracts, the joint venture partners would be jointly and severally liable for any losses incurred by the client due to the failure to perform. Legal Matters We are a party to a number of lawsuits, claims, and proceedings incident to the operation of our business, including those pertaining to labor and employment, contracts, personal injury, and other matters, some of which allege substantial monetary damages. Some of these actions may be brought as a class action on behalf of a class or purported class of employees. At April 30, 2016 , the total amount accrued for all probable litigation losses where a reasonable estimate of the loss could be made was $11.4 million . Litigation outcomes are difficult to predict and the estimation of probable losses requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. There is the potential for a material adverse effect on our financial statements if one or more matters are resolved in a particular period in an amount materially in excess of what we anticipated. We do not accrue for contingent losses that, in our judgment, are considered to be reasonably possible but not probable. The estimation of reasonably possible losses also requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. Our management currently estimates the range of loss for all reasonably possible losses for which a reasonable estimate of the loss can be made is between zero and $14 million , which excludes the Augustus and Bucio cases discussed below. Factors underlying this estimated range of loss may change from time to time, and actual results may vary significantly from this estimate. In some cases, although a loss is probable or reasonably possible, we cannot reasonably estimate the maximum potential losses for probable matters or the range of losses for reasonably possible matters. Therefore, our accrual for probable losses and our estimated range of loss for reasonably possible losses do not represent our maximum possible exposure. While the results of these proceedings, claims, and inquiries cannot be predicted with any certainty, our management believes that the final outcome of these matters will not have a material adverse effect on our consolidated financial statements, results of operations, or cash flows. Certain Legal Proceedings Certain pending lawsuits to which we are a party are discussed below. In determining whether to include any particular lawsuit or other proceeding, we consider both quantitative and qualitative factors. These factors include, but are not limited to: the amount of damages and the nature of any other relief sought in the proceeding; if such damages and other relief are specified, our view of the merits of the claims; whether the action is or purports to be a class action, and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; and the potential impact of the proceeding on our reputation. The Consolidated Cases of Augustus, Hall and Davis v. American Commercial Security Services, filed July 12, 2005, in the Superior Court of California, Los Angeles County (the “Augustus case”) The Augustus case is a certified class action involving alleged violations of certain California state laws relating to rest breaks. The case centers on whether requiring security guards to remain on call during rest breaks violated Section 226.7 of the California Labor Code. On February 8, 2012 , the plaintiffs filed a motion for summary judgment on the rest break claim, and on July 31, 2012, the Superior Court of California, Los Angeles County (the “Superior Court”), entered judgment in favor of plaintiffs in the amount of approximately $89.7 million (the “common fund”). Subsequently, the Superior Court also awarded plaintiffs’ attorneys’ fees of approximately $4.5 million in addition to approximately 30% of the $89.7 million common fund. We appealed the Superior Court’s rulings to the Court of Appeals of the State of California, Second Appellate District (the “Appeals Court”). On December 31, 2014 , the Appeals Court issued its opinion, reversing the judgment in favor of the plaintiffs and vacating the award of $89.7 million in damages and the attorneys’ fees award. Plaintiffs requested rehearing of the Appeals Court’s decision to reverse the judgment in favor of plaintiffs and vacate the damages award. On January 29, 2015 , the Appeals Court denied the plaintiffs’ request for rehearing, modified its December 31, 2014 opinion, and certified the opinion for publication. The Appeals Court opinion held that “on-call rest breaks are permissible” and remaining on call during rest breaks does not render the rest breaks invalid under California law. The Appeals Court explained that “although on-call hours constitute ‘hours worked,’ remaining available to work is not the same as performing work.... Section 226.7 proscribes only work on a rest break.” The plaintiffs filed a petition for review with the California Supreme Court on March 4, 2015 , and on April 29, 2015 , the California Supreme Court granted the plaintiffs’ petition. No date has been set for oral argument. We believe that the Appeals Court correctly ruled in our favor, and we look forward to presenting our arguments to the California Supreme Court. The Consolidated Cases of Bucio and Martinez v. ABM Janitorial Services filed on April 7, 2006, in the Superior Court of California, County of San Francisco (the “Bucio case”) The Bucio case is a purported class action involving allegations that we failed to track work time and provide breaks. On April 19, 2011 , the trial court held a hearing on plaintiffs’ motion to certify the class. At the conclusion of that hearing, the trial court denied plaintiffs’ motion to certify the class. On May 11, 2011 , the plaintiffs filed a motion to reconsider, which was denied. The plaintiffs have appealed the class certification issues. The trial court stayed the underlying lawsuit pending the decision in the appeal. On August 30, 2012 , the plaintiffs filed their appellate brief on the class certification issues. We filed our responsive brief on November 15, 2012 . Oral argument relating to the appeal has not been scheduled. Plaintiffs Evelia Davila, Elizabeth Marcos, and Angelica Aguilar v. ABM Janitorial Services, Inc., ABM, Jeremias Rivera, and Rene Quintanar, filed on April 6, 2012 in the Superior Court of Los Angeles County, California (the “Davila” case). A Second Amended Complaint was filed on August 13, 2012. We are a defendant in the Davila case. Plaintiffs are three former janitors who have made various allegations of sexual harassment and discrimination, assault and battery, retaliation, wrongful discharge, discrimination based on disability and age, and related claims against ABM, a former co-worker, and a former ABM human resources representative. Following a settlement conference during the first quarter of 2016, the parties agreed to a settlement in an amount that is reflected in our accruals for probable litigation losses. We have employment practices liability insurance that covers us for this case, subject to our negotiated retention. We recorded this liability at the gross amount of the settlement and the corresponding insurance recoverable as an asset. During the three months ended April 30, 2016 , we received the insurance proceeds, which were net of our negotiated retention. The settlement amount was paid after April 30, 2016. Other During October 2011 , we began an internal investigation into matters relating to compliance with the U.S. Foreign Corrupt Practices Act and our internal policies in connection with services provided by a foreign entity affiliated with a former joint venture partner of The Linc Group, LLC (“Linc”). Such services commenced prior to the acquisition of Linc. As a result of the investigation, we caused Linc to terminate its association with the arrangement. In December 2011 , we contacted the U.S. Department of Justice and the Securities and Exchange Commission to voluntarily disclose the results of our internal investigation to date, and we are cooperating with the government’s investigation. We cannot reasonably estimate the potential liability, if any, related to these matters. However, based on the facts currently known, we do not believe that these matters will have a material adverse effect on our business, financial position, results of operations, or cash flows.

Segment Information	SEGMENT INFORMATION During the fourth quarter of 2015 , we sold our Security business, which was previously a separate reportable segment. This business is now included within discontinued operations for all periods presented, and we have revised our segment results accordingly. Refer to Note 4 , “Discontinued Operations,” for further information. We currently have five reportable segments: Janitorial, Facility Services, Parking, Building & Energy Solutions, and Other. The accounting policies for our segments are the same as those disclosed within our significant accounting policies in Note 2 , “Basis of Presentation and Significant Accounting Policies.” Our management evaluates the performance of each reportable segment based on its respective operating profit results, which include the allocation of certain centrally incurred costs. Corporate expenses not allocated to segments include: • certain CEO and other finance and human resource departmental costs; • certain information technology costs; • share-based compensation costs; • certain legal costs and settlements; • restructuring and related charges; • certain adjustments resulting from actuarial developments of self-insurance reserves; and • direct acquisition costs.

Accordingly, such financial statements do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments that are necessary for the fair statement of the interim periods presented. Interim results of operations are not necessarily indicative of the results for the full year. The Financial Statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) in our Annual Report on Form 10-K for the fiscal year ended October 31, 2015 (“Annual Report”). Unless otherwise noted, all references to years are to our fiscal year, which ends on October 31 . Rounding We round amounts in the Financial Statements to millions and calculate all percentages and per-share data from the underlying whole-dollar amounts. As a result, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.

The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. (2) For investments in auction rate securities, the fair value was based on discounted cash flow valuation models, primarily utilizing unobservable inputs. These amounts are included in “Other investments” on the accompanying unaudited consolidated balance sheets. See Note 9 , “Auction Rate Securities,” for further information. (3) Represents interest rate swap derivatives designated as cash flow hedges. The fair values of the interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for LIBOR forward rates at the end of the period. For 2016 the interest rate swap was included in “Other noncurrent assets,” and for 2015 the interest rate swaps were included in “Other accrued liabilities” on the accompanying unaudited consolidated balance sheets. See Note 11 , “Line of Credit,” for more information. (4) Cash and cash equivalents are stated at nominal value, which equals fair value. (5) Represents restricted insurance deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets. See Note 10 , “Insurance,” for further information. (6) Certain of our acquisitions involve the payment of contingent consideration. Depending on the structure of the contingent consideration arrangement, the fair value of the liability is based on either (i) the expected achievement of certain pre-established revenue goals or (ii) pre-defined forecasted adjusted income from operations using a probability weighted income approach. Our contingent consideration liabilities are included in “Other accrued liabilities” and “Other noncurrent liabilities” on the accompanying unaudited consolidated balance sheets. (7) Represents outstanding borrowings under our syndicated line of credit. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit approximates the fair value. See Note 11 , “Line of Credit,” for further information.
