Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The consolidated financial statements and accompanying notes (the “Financial Statements”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Prior year amounts have been reclassified to conform with the current year presentation for amounts related to discontinued operations (see Note 4, “Discontinued Operations”) and segment reporting (see Note 19, “Segment and Geographic Information”). Unless otherwise noted, all references to years are to our fiscal year, which ends on October 31.

Principles of Consolidation

The Financial Statements include the accounts of ABM and all of our consolidated subsidiaries. We account for ABM’s investments in unconsolidated affiliates under the equity method of accounting. We include the results of acquired businesses in the consolidated statements of comprehensive income from their respective dates of acquisition. All intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of consolidated financial statements in accordance with U.S. GAAP requires our management to make certain estimates that affect the reported amounts. We base our estimates on historical experience, known or expected trends, independent valuations, and various other assumptions that we believe to be reasonable under the circumstances. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates.

Significant Accounting Policies

Cash and Cash Equivalents

We consider all investments purchased with an original maturity of three months or less to be cash and cash equivalents. We present the change in book cash overdrafts (i.e., negative book cash balances that have not been presented to the bank for payment) as cash flows from financing activities.

Trade Accounts Receivable

Trade accounts receivable arise from services provided to our clients and are usually due and payable on varying terms from receipt of the invoice to net ninety days, with the exception of certain U.S. Government receivables that generally have longer collection periods. Our trade accounts receivables are recorded at the invoiced amount and normally do not bear interest. In addition, our trade accounts receivable includes unbilled receivables that represent costs and estimated earnings in excess of billings on uncompleted contracts related to fixed-price repair and refurbishment arrangements.

Allowance for Doubtful Accounts

We estimate the allowance for doubtful accounts based on a variety of factors, including an analysis of the historical rate of credit losses or write-offs, specific client concerns, and known or expected trends. Additionally, a specific reserve is established upon the earlier of a client’s inability to meet its financial obligations or after a period of twelve months, unless our management believes such amounts will ultimately be collectible. We do not believe that we have any material exposure due to either industry or regional concentrations of credit risk. Further, no client accounted for more than 10% of our consolidated revenues during 2015, 2014, or 2013.

Sales Allowance

In connection with our service contracts, we periodically issue credit memos to our clients. As such, we make estimates for potential future losses on client receivables, which are recorded as a reduction in revenues and an increase to the allowance for billing adjustments. These credits can result from client vacancy discounts, job cancellations, property damage, and other items. Our sales allowance estimate is based on an analysis of the historical rate of sales adjustments (credit memos, net of re-bills) and considers known current or expected trends.

Other Current Assets

At October 31, 2015 and 2014, other current assets primarily consisted of other receivables and short-term insurance recoverables.

Other Investments

At October 31, 2015 and 2014, other investments primarily consisted of investments in unconsolidated affiliates and investments in auction rate securities.

Investments in Unconsolidated Affiliates

We own non-controlling interests (generally 20% to 50%) in certain affiliated entities that predominantly provide facility solutions to governmental and commercial clients, primarily in the United States and the Middle East. We account for such investments under the equity method of accounting. We evaluate our equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amounts of such investments may not be recoverable. An impairment loss is recognized to the extent that the estimated fair value of the investment is less than its carrying amount and we determine that the impairment is other-than-temporary. At October 31, 2015 and 2014, our investments in unconsolidated affiliates were $22.6 million and $20.0 million, respectively. In 2015, 2014, and 2013, we did not have any impairment losses.

Investments in Auction Rate Securities

Our investments in auction rate securities are classified as available for sale. Accordingly, auction rate securities are presented at fair value with unrealized gains and losses excluded from earnings and recorded in accumulated other comprehensive loss (“AOCL”). A decline in the fair value of available-for-sale securities below their cost or amortized cost that are deemed to be other-than-temporary are reflected in earnings. The credit loss component of an other-than-temporary impairment (“OTTI”) is recorded in earnings in the period identified. We estimate the fair values utilizing a discounted cash flow model, which considers, among other factors, assumptions about the following items:

Assumptions

(1) the underlying collateral

(2) credit risks associated with the issuer

(3) contractual maturity

(4) credit enhancements associated with financial insurance guarantees, if any

(5) the possibility of the security being re-financed by the issuer or having a successful auction

Our determination of whether our auction rate securities are other-than-temporarily impaired is based on an evaluation of several factors, circumstances, and known or reasonably supportable trends including, but not limited to the following:

OTTI Evaluation Factors

(1) our intent to hold the securities

(2) our assessment that it is not more likely than not that we will be required to sell the securities before recovering our cost basis

(3) expected defaults

(4) available ratings for the securities or the underlying collateral

(5) the rating of the associated guarantor (where applicable)

(6) the nature and value of the underlying collateral expected to service the investment

(7) actual historical performance of the security in servicing its obligations

(8) actuarial experience of the underlying re-insurance arrangement (where applicable), which in certain circumstances may have preferential rights to the underlying collateral

Our determination of whether an OTTI represents a credit loss is based upon the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the security. Significant assumptions include, but are not limited to: (1) default rates for the security and the mono-line insurer, if any (which are based on published historical default rates of similar securities and consideration of current market trends); and (2) the expected life of the security (which represents our view of when market efficiencies for securities may be restored). Adverse changes in any of these factors could result in additional declines in fair value and further OTTIs in the future. See Note 9, “Auction Rate Securities,” for additional information.

Property, Plant and Equipment

We record property, plant and equipment at cost. Repairs and maintenance expenditures are expensed as incurred. In contrast, we capitalize major renewals or replacements that substantially extend the useful life of an asset. We determine depreciation for financial reporting purposes using the straight-line method over the following estimated useful lives:



	Years*
Computer equipment and software	3–5
Machinery and other equipment	3–5
Transportation equipment	1.5–10
Buildings	10–40
Furniture and fixtures	5

*We depreciate assets under capital leases and leasehold improvements over the shorter of their estimated useful lives or the remaining lease term.

Upon retirement or the sale of an asset, we remove the cost and accumulated depreciation from the accounts. When applicable, we record corresponding gains or losses within the accompanying consolidated statements of comprehensive income.

Leases

We enter into various noncancelable lease agreements for premises and equipment used in the normal course of business. We evaluate the lease agreement at the inception of the lease to determine whether the lease is an operating or capital lease.

We account for rent expense under noncancelable operating leases with escalation clauses on a straight-line basis over the initial lease term. A deferred liability is recorded for the amount of the excess of straight-line rent expense over scheduled payments. We do not assume renewals in our determination of the lease term unless the renewals are deemed to be reasonably assured at lease inception. We may also be required to make additional payments to reimburse the lessors for operating expenses such as real estate taxes, maintenance, utilities, and insurance, which are expensed as incurred.

Within our Parking business, we enter into leases of parking lots and garages that contain contingent payment provisions. Under these provisions, we pay contingent amounts in addition to base rent, primarily based on percentages of the gross receipts or other financial parameters attributable to the related facilities. We record contingent rent as it becomes probable that specified targets will be met.

We record capital leases as an asset and an obligation at an amount that is equal to the present value of the minimum lease payments over the lease term.

Other Intangible Assets

Other intangible assets primarily consist of acquired customer contracts and relationships that are amortized using the sum-of-the-years-digits method over their useful lives, consistent with the estimated useful life considerations used in the determination of their fair values. This accelerated method of amortization reflects the pattern in which the economic benefits from the intangible assets of customer contracts and relationships are expected to be realized. We amortize other non-customer acquired intangibles using a straight-line method of amortization.

Impairment of Long-Lived Assets

We evaluate our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. When this occurs, a recoverability test is performed that compares the projected undiscounted cash flows from the use and eventual disposition of an asset or asset group to its carrying amount. If as a result of this test we conclude that the projected undiscounted cash flows are less than the carrying amount, an impairment would be recorded for the excess of the carrying amount over the estimated fair value.

Goodwill

Goodwill represents the excess purchase price of acquired businesses over the fair values of the assets acquired and liabilities assumed. We have elected to make the first day of our fiscal fourth quarter, August 1st, the annual impairment assessment date for goodwill. However, we could be required to evaluate the recoverability of goodwill prior to the annual assessment if we experience a significant change in the business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of one of our businesses.

We test the carrying value of goodwill for impairment at a “reporting unit” level using a two-step approach. The first step of the process is to evaluate whether the fair value of a reporting unit is less than its carrying value, which is an indicator that the goodwill assigned to that reporting unit may be impaired. In this case, a second step of impairment testing is performed to allocate the fair value of the reporting unit to the assets and liabilities of the reporting unit as if it had just been acquired in a business combination, and as if the purchase price was equivalent to the fair value of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to its assets and liabilities is referred to as the implied fair value of goodwill. The implied fair value of the reporting unit’s goodwill is then compared to the actual carrying value of goodwill. If the implied fair value is less than its carrying value, we would record an impairment for the excess of the carrying amount over the estimated fair value.

Other Noncurrent Assets

At October 31, 2015 and 2014, other noncurrent assets primarily consisted of long-term insurance recoverables, insurance and other long-term deposits, prepayments to carriers for future insurance claims, and other long-term receivables.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In making our determination of the fair value measurements for our financial assets and liabilities, we consider the principal or most advantageous market in which we would transact, as well as the assumptions that market participants would use when pricing the asset or liability.

Authoritative guidance requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1 – Quoted prices for identical assets or liabilities in active markets;

Level 2 – Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs or significant value drivers are observable in active markets; and

Level 3 – Unobservable inputs for the asset or liability.

See Note 7, “Fair Value of Financial Instruments,” for the fair value hierarchy table and for details on how we measure fair value for financial assets and liabilities.

Acquisitions

On the date of acquisition, we allocate the purchase price to the assets acquired and liabilities assumed at their estimated fair values. The excess of the purchase price over the amount allocated to the assets acquired and liabilities assumed is recorded as goodwill. Acquisition-related costs are expensed as incurred.

Our acquisitions may include contingent consideration that requires us to recognize the fair value of the estimated contingency at the time of the acquisition. We recognize subsequent changes in the estimate of the amount to be paid under contingent consideration arrangements in the accompanying consolidated statements of comprehensive income. We classify payments that do not exceed the acquisition-date fair value of a contingent consideration liability arrangement as cash flows used in financing activities. In contrast, we report amounts paid in excess of the original acquisition date fair value as operating activities.

Discontinued Operations

To be reported within discontinued operations, we must dispose of a component or a group of components that represents a strategic shift which will have a major effect on our operations and financial results.

We aggregate the results of operations for discontinued operations within a single line item on the income statement. General corporate overhead is not allocated to discontinued operations. We disclose any gain or loss that is recognized upon the disposition of a discontinued operation. Prior to disposition, we aggregate the assets and liabilities of discontinued operations and report the amounts on separate line items within the balance sheet.

For the sale of business components that do not meet the discontinued operation criteria, we record gains and losses within continuing operations, and separately disclose such amounts, if significant.

Insurance Reserves

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. Insurance claim liabilities represent our estimate of retained risks without regard to insurance coverage. We retain a substantial portion of the risk related to certain workers’ compensation and medical claims. Liabilities associated with these losses include estimates of both claims filed and “incurred but not reported” claim costs.

With the assistance of third-party professionals, we periodically review our estimate of ultimate losses for “incurred but not reported” claim costs and adjust our required self-insurance reserves as appropriate. As part of this evaluation, we review the status of existing and new claim reserves as established by our third-party claims administrators. Our third-party administrators establish the case reserves based upon known factors related to the type and severity of the claims, demographic factors, legislative matters, and case law, as appropriate. We compare actual trends to expected trends and monitor claims developments. The specific case reserves estimated by the third-party administrators are provided to an actuary who assists us in projecting an actuarial estimate of the overall ultimate losses for our self-insured or high deductible programs, which includes the case reserves plus an actuarial estimate of reserves required for additional developments including “incurred but not reported” claim costs. We utilize the independent third-party administrator’s actuarial point estimate, reviewed by our management, to adjust our carried self-insurance reserves.

In general, our reserves are recorded on an undiscounted basis. We allocate current-year insurance expense to our operating segments based upon their underlying exposures, while actuarial adjustments related to prior year claims are recorded within Corporate expenses. We classify claims as current or long-term based on the expected settlement date. Estimated insurance recoveries related to recorded liabilities are reflected as assets in our consolidated balance sheets when we believe that the receipt of such amounts is probable.

Other Accrued Liabilities

At October 31, 2015 and 2014, other accrued liabilities primarily consisted of accrued employee benefits, progress billings in excess of costs related to fixed-price repair and refurbishment arrangements, deferred revenue, accrued legal fees and settlements, dividends payable, and other accrued expenses.

Other Noncurrent Liabilities

At October 31, 2015 and 2014, other noncurrent liabilities primarily consisted of retirement plan liabilities, deferred compensation, and deferred rent.

Revenue Recognition

We earn revenue under various types of service contracts. In all forms of service we provide, revenue is recognized when persuasive evidence of an arrangement exists, services have been rendered, the fee is fixed or determinable, and collectability is reasonably assured. The various types of service contracts are described below.



Contract Type		Description
Monthly Fixed-Price		These arrangements are contracts in which the client agrees to pay a fixed fee every month over a specified contract term. A variation of a fixed-price arrangement is a square-foot arrangement, under which monthly billings are based on the actual square footage serviced.
Transaction-Price		These arrangements are agreements in which the clients are billed for each transaction performed on a monthly basis (e.g., wheelchair passengers served, aircrafts cleaned).
Hourly		These arrangements are contracts in which the client is billed a set hourly rate for each labor hour provided.
Cost-Plus		These arrangements are contracts in which the clients reimburse us for the agreed-upon amount of wages and benefits, payroll taxes, insurance charges, and other expenses associated with the contracted work, plus a profit margin.
Tag		Tag work generally consists of supplemental services requested by clients outside of the standard service specification. Examples are cleanup after tenant moves, construction cleanup, flood cleanup, snow removal, and extermination services.
Parking Reimbursement		Under parking reimbursement arrangements, we manage the parking facility for a management fee, and we pass through the revenue and expenses associated with the facility to the owner. Revenues and expenses are reported in equal amounts for costs reimbursed from our managed locations. During 2015, 2014, and 2013, such amounts totaled $305.9 million, $306.1 million, and $302.4 million, respectively.
Fixed-Price Repair and Refurbishment		These arrangements are accounted for under the percentage-of-completion method of accounting, most often based on the cost-to-cost method. Under the percentage-of-completion method, revenues are recognized as the work progresses. The percentage of work completed is determined principally by comparing the actual costs incurred to date with the current estimate of total costs to complete. Under the percentage-of-completion method, recognition of profit is dependent upon the accuracy of a variety of estimates, including engineering progress, achievement of milestones, incentives, labor productivity, and cost estimates. Such estimates are based on various professional judgments made with respect to those factors and are subject to change as each project proceeds and new information becomes available. Revenue and gross profit are adjusted periodically for revisions in estimated total contract costs and values. Estimated losses are recorded when identified.
Franchise		We franchise certain engineering services under the Linc Network and TEGG brands through individual and area franchises. Initial franchise fees are recognized when we have performed substantially all initial services required by the franchise agreement. Royalties are recognized in income as underlying franchisee sales occur. Franchise fees charged to franchisees on a flat rate are recognized as earned. Direct (incremental) costs related to new franchise sales for which the revenue has not been recognized are deferred until the related revenue is recognized. We expense costs related to continuing franchise royalty fees as incurred.

Exit and Disposal Activities

Exit and disposal activities primarily consist of various actions to terminate employees, exit certain contractual obligations, and dispose of certain assets. Our methodology used to record these expenses are described below:

Severance

We recognize severance costs using the provisions of Accounting Standards Codification (“ASC”) ASC 712, Nonretirement Postemployment Benefits, and ASC 420, Exit or Disposal Cost Obligations.

ASC 712 relates to ongoing benefit arrangements. As we do not have a past history of consistently providing severance benefits that would constitute a substantive plan, we typically apply this accounting to executives with employment agreements. As such, we accrue for these separation liabilities when it is probable that the impacted executives will be entitled to the benefits and the amount can be reasonably estimated.

In contrast, ASC 420 relates to one-time termination benefits. This accounting normally applies to employees who do not have formal employment agreements. Under ASC 420, severance costs are recognized when management with the proper level of authority has committed to a restructuring plan and communicated those actions to employees. In addition, if employees are required to render service beyond the minimum retention period until they are terminated in order to receive the benefits, a liability is recognized ratably over the future service period.

Noncancelable Leases and Contractual Obligations

We apply the provisions of ASC 420 for noncancelable leases and contractual obligations. As such, we record liabilities when we terminate a contract in accordance with the contract terms or when we exit the leased space. The expense for these items is determined based on the fair value of remaining lease rentals reduced by the fair value of estimated sublease rentals that could reasonably be obtained for the property, estimated using a present value technique.

Other

For other costs associated with exit and disposal activities, we apply the provisions of ASC 420. We recognize an expense at fair value in the period in which the liability is incurred.

Advertising

Advertising costs are expensed as incurred. During 2015, 2014, and 2013, advertising expense was $2.8 million, $6.8 million, and $7.1 million, respectively.

Share-Based Compensation

Our outstanding share-based awards principally consist of restricted stock units (“RSUs”), stock options, and various performance share awards. The fair value of RSUs, stock options, and total shareholder return (“TSR”) performance share awards are expensed over the requisite service period. Other performance share awards are expensed over the requisite service period based on the probability of achievement of performance criteria. The fair value of RSUs and certain performance share awards is determined based on the fair value of our stock price on the date of grant. We use the Black-Scholes option pricing model to determine the fair value of our stock option grants. Since our TSR performance share awards are performance awards with a market condition, the fair value of these awards are determined using a Monte Carlo simulation valuation model. We record share-based compensation expense within selling, general and administrative expenses.

Taxes Collected from Clients and Remitted to Governmental Agencies

We record taxes on client transactions due to governmental agencies as receivables and liabilities on the consolidated balance sheets.

Income Taxes

Our provision for income taxes is based on domestic and international statutory income tax rates in the tax jurisdictions where we operate, permanent differences between financial reporting and tax reporting, and available credits and incentives.

We recognize deferred income taxes for the future tax effects of temporary differences between financial and income tax reporting using tax rates in effect for the years in which the differences are expected to reverse. Deferred tax assets are reviewed for recoverability quarterly. We classify the deferred income taxes as current or long-term based on the classification of the related asset or liability.

Our deferred tax assets are reduced by a valuation allowance when, in the opinion of our management, it is more likely than not that all or a portion of the deferred tax assets will not be realized.

All or a portion of the benefit of income tax positions is recognized only when we have made a determination that it is more likely than not that the tax position will be sustained upon examination, based upon the technical merits of the position and other factors. For tax positions that are determined as more likely than not to be sustained upon examination, the tax benefit recognized is the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement. We include interest and penalties related to unrecognized tax benefits in income tax expense.

Net Income Per Common Share

Basic net income per common share is net income divided by the weighted-average number of shares outstanding during the period. Diluted net income per common share is based on the weighted-average number of shares outstanding during the period, adjusted to include the assumed conversion of RSUs, vesting of performance shares, and exercise of stock options.

Contingencies and Litigation

We are a party to a variety of actions, proceedings, and legal, administrative, and other inquiries arising in the normal course of business relating to labor and employment, contracts, personal injury, and other matters. We accrue for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range and no amount within the range is a better estimate, the minimum amount of the range is recorded as a liability. We recognize legal costs as an expense in the period incurred.

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”). The 2020 Vision 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 is positioned to continue to competitively offer value added services to clients over the long-term. As a result of our 2020 Vision, we recorded a total charge of $12.7 million in 2015. These restructuring and related costs were primarily related to employee severance, external support fees, asset impairment, and other costs.

(1) These costs were recorded in selling, general and administrative on the accompanying consolidated statements of comprehensive income. The results by segment, as disclosed in Note 19, “Segment Information,” exclude these costs, which is consistent with the manner by which management evaluates the performance of each reportable segment based on its respective operating profit results. As such, these costs are included with Corporate expenses.

(2) In connection with our 2020 Vision, we wrote down our investment in certain proprietary task management software in the fourth quarter.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS 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, subject to post-closing adjustments. 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. 2014 Acquisitions During 2014, we completed acquisitions for an aggregate purchase price of $52.9 million, which includes $3.3 million of contingent consideration. As of October 31, 2015, the remaining balance of this contingent consideration is $2.8 million. There were no material purchase price allocation adjustments recognized in the current period related to business combinations that occurred in 2014. 2013 Acquisitions Air Serv Acquisition On November 1, 2012, we acquired all of the outstanding stock of Air Serv Corporation (“Air Serv”) for an aggregate purchase price of $162.9 million in cash (the “Air Serv Acquisition”). Air Serv provides facility solutions for airlines, airports, and freight companies at airports primarily in the United States. This acquisition allowed us to significantly expand our vertical market expertise in servicing the comprehensive needs of airline and airport authorities, which resulted in the allocation of a significant portion of the purchase price to goodwill. As such, we recorded goodwill and intangible assets associated with this acquisition of $89.2 million and $44.6 million, respectively. Other Acquisitions During 2013, we completed other acquisitions for an aggregate purchase price of $49.9 million, which includes $1.6 million of contingent consideration. The contingent consideration was adjusted by $0.2 million in 2014 to reflect the probable achievement of the final settlement of the contingent consideration liability. This adjustment was recorded in selling, general and administrative on the accompanying consolidated statements of comprehensive income. Pro Forma and Other Supplemental Financial Information Pro forma and other supplemental financial information is not presented, as these acquisitions are not considered material business combinations individually or on a combined basis.

The entire disclosure for a business combination (or series of individually immaterial business combinations) completed during the period, including background, timing, and recognized assets and liabilities. The disclosure may include leverage buyout transactions (as applicable).

(1) Represents investments held in a Rabbi trust associated with one of our deferred compensation plans, which we include in “Other noncurrent assets” on the accompanying consolidated balance sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. See Note 14, “Employee Benefit Plans,” for further information.

(2) For investments in auction rate securities, the fair values are based on discounted cash flow valuation models, primarily utilizing unobservable inputs, which we include in “Other investments” on the accompanying consolidated balance sheets. See Note 9, “Auction Rate Securities,” for further information.

(3) Cash and cash equivalents are stated at nominal value, which equals fair value.

(4) 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 consolidated balance sheets. See Note 12, “Insurance,” for further information.

(5) 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. The fair values of the interest rate swap liabilities are included in “Other accrued liabilities” for 2015 and “Other noncurrent liabilities” for 2014, on the accompanying consolidated balance sheets. See Note 13, “Line of Credit,” for more 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 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 13, “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 2015, we wrote down our investment in certain proprietary task management software in the fourth quarter. See Note 3, “Restructuring and Related Costs,” for further information.

During 2015 and 2014, 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 and 2014, we held investments in auction rate securities from three different issuers having an aggregate original principal amount of $15.0 million and an amortized cost basis of $13.0 million. At October 31, 2015 and 2014, the fair value of these securities was $13.0 million. Our auction rate securities are debt instruments with stated maturities ranging from 2033 to 2050, for which the interest rate is designed to be reset through Dutch auctions approximately every thirty days. Auctions for these securities have not occurred since August 2007. We have classified all our auction rate security investments as noncurrent, as we do not reasonably expect to liquidate the securities for cash within the next twelve months.

At October 31, 2015 and 2014, there were no unrealized gains or losses included in 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 between $1.0 million and $5.0 million per occurrence. To cover general liability losses above these primary limits, we maintain commercial insurance umbrella 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 limits of $75.0 million.

During 2015, our annual actuarial evaluations were performed for the majority of our casualty insurance programs, including those related to certain previously acquired businesses. For 2015, the actuarial evaluations showed unfavorable developments in our estimate of ultimate losses related to certain general liability, workers’ compensation, and automobile liability claims, as explained below. These evaluations indicated that previously estimated decreases in our average claim cost and the anticipated reduction in the total number of claims have not occurred at the pace contemplated in the 2014 evaluations.

General Liability. The actuarial evaluations showed that while the total number of general liability claims has remained relatively stable, the ratio of alleged bodily injury claims as compared to the total number of general liability claims has increased. The shift in the claim-type mix, coupled with an increase in the number of premises liability claims from earlier years reported to us subsequent to the 2014 actuarial evaluations, resulted in increases to our estimate of ultimate losses.

Workers’ Compensation. Our workers’ compensation claim development patterns in the majority of states in which we provide services, coupled with an increase in claims frequency in California, also warranted increases to our estimate of ultimate losses. This adverse development can be attributed to an increase in the statutory benefits paid to the claimants as well as to increases in administrative and legal expenses associated with claims in which settlements cannot be quickly attained.

Automobile Liability. We operate a fleet of passenger vehicles, service vans, and shuttle buses associated with our various transportation service contracts. Subsequent to last year’s actuarial review, the adverse development trend of the claims related to operating these vehicles was primarily attributable to three large multi-party claims that occurred in the 2013 policy year. Additionally, during the last 12 months, the claims frequency associated with our continuing fleet operations trended unfavorably versus the actuarial expectations.

After analyzing the recent loss development patterns, comparing the loss developments against benchmarks, and applying actuarial projection methods to determine the estimate of ultimate losses, we increased our total reserves by $42.4 million during 2015. For 2014 and 2013, insurance reserve adjustments resulting from periodic actuarial evaluations totaled $4.7 million and $9.5 million, respectively.

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. During 2015, actuarial evaluations were completed for our medical and dental plans for the calendar year ended December 31, 2014. The results of the actuarial evaluations indicated a higher than expected incurred but not reported liability for medical and dental claims. As a result, we increased our reserves by $3.0 million in 2015, which was recorded as part of Corporate expenses.

At October 31, 2015 and 2014, we had insurance claim reserves totaling $387.4 million and $349.7 million, respectively, which include $8.1 million and $4.8 million in reserves, respectively, related to our medical and dental self-insured plans. At October 31, 2015 and 2014, we also had insurance recoverables, which we include in “Other current assets” and “Other noncurrent assets” on the accompanying consolidated balance sheets, totaling $65.9 million and $66.4 million, respectively.

Debt Disclosure [Abstract]
Line of Credit	LINE OF CREDIT On November 30, 2010, we entered into a five-year 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.” The aggregate amount of the Credit Agreement is $800.0 million, and the current maturity date of the Facility is December 11, 2018. At our option, we may increase the size of the Facility to $1.0 billion at any time prior to the 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 leverage and 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. On September 2, 2015, we entered into an amendment to our Credit Agreement to update the definition of Consolidated EBITDA that is used in the calculation of certain leverage and financial covenants. The revised definition of Consolidated EBITDA provides addbacks for: (i) restructuring and related charges arising out of our 2020 Vision, (ii) adjustments with respect to insurance liabilities for periods prior to 2015, and (iii) costs arising from the consolidation of locations, subject to the limitation that the aggregate amount of all addbacks does not exceed $75.0 million. In addition, the amendment permits us to dispose of certain assets and to repurchase our common stock without regard to a cap so long as certain leverage tests are met. As of October 31, 2015, 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 obligations. 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. At October 31, 2015, the total outstanding amounts under the Facility in the form of cash borrowings and standby letters of credit were $158.0 million and $112.9 million, respectively. At October 31, 2014, the total outstanding amounts under the Facility in the form of cash borrowings and standby letters of credit were $319.8 million and $114.9 million, respectively. At October 31, 2015 and 2014, we had up to $529.1 million and $365.3 million borrowing capacity, respectively, under the Facility, the availability of which was subject to, and limited by, compliance with the covenants described above. Interest Rate Swaps During 2013, we entered into a series of interest rate swap agreements with effective start dates of March 18, 2013 and April 11, 2013, totaling an underlying aggregate notional amount of $155.0 million, pursuant to which we receive variable interest payments based on LIBOR and pay fixed interest on such amounts, at rates ranging from 0.44% to 0.47%. These interest rate swap agreements will mature between March 18, 2016 and April 11, 2016 and are intended to hedge the interest rate risk associated with our floating-rate, LIBOR-based borrowings under our Facility. The swaps were designated and accounted for as cash flow hedges from inception. We recognize all interest rate swaps on the accompanying consolidated balance sheets at fair value. 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. See Note 7, “Fair Value of Financial Instruments,” for more information. Each of the swap derivatives is designated as a cash flow hedge, and 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 October 31, 2015 and 2014, the amounts recorded in AOCL were $0.1 million ($0.1 million, net of taxes) and $0.2 million ($0.1 million, net of taxes), respectively. At October 31, 2015, the amount expected to be reclassified from AOCL to earnings during the next twelve months was $0.1 million

Employee Benefit Plans

EMPLOYEE BENEFIT PLANS

Defined Benefit Plans

We provide benefits to certain employees under various defined benefit and postretirement benefit plans (collectively, the “Plans”). The Plans were previously amended to preclude new participants. All but one of the Plans are unfunded. At October 31, 2015 and 2014, we recorded aggregate net obligations of $7.4 million and $8.2 million, respectively, for the Plans. At October 31, 2015 and 2014, the projected benefit obligations in the aggregate for the Plans was $15.6 million and $16.0 million, respectively. The fair value of the Plans’ assets was $8.2 million and $7.8 million, at October 31, 2015 and 2014, respectively. At October 31, 2015, approximately 53% of the Plan assets were invested in equities, 30% in fixed income, and 17% in cash. The expected return on assets was $0.5 million during both of 2015 and 2014 and $0.4 million for 2013. The aggregate net periodic benefit cost for all the Plans was $0.2 million for 2015 and $0.4 million for both 2014 and 2013. Future benefit payments in the aggregate are expected to be $13.6 million.

Deferred Compensation Plans

We maintain various deferred compensation plans that permit eligible employees and directors to defer a portion of their compensation. At October 31, 2015 and 2014, the total liability of all deferred compensation was $19.5 million and $20.0 million, respectively, and these amounts are included in “Other accrued liabilities” and “Other noncurrent liabilities” on the accompanying consolidated balance sheets. Under one of our deferred compensation plans, a Rabbi trust was created to fund the obligations, and we are required to contribute a portion of the deferred compensation contributions for eligible participants. The assets held in the Rabbi trust are not available for general corporate purposes. At October 31, 2015 and 2014, the fair value of these assets was $5.3 million and $5.4 million, respectively, and was included in “Other noncurrent assets” on the accompanying consolidated balance sheets. Aggregate expense recognized under these deferred compensation plans was $0.5 million for both 2015 and 2014 and $0.4 million for 2013.

Defined Contribution Plans

We sponsor three defined contribution plans covering certain employees that are subject to the applicable provisions of the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code (“IRC”). Certain plans permit a company match of a portion of the participant’s contributions or a discretionary contribution after the participant has met the eligibility requirements set forth in the plan. During 2015, 2014, and 2013, we made matching contributions required by the plans of $12.1 million, $10.0 million, and $9.3 million, respectively.

Multiemployer Pension and Postretirement Plans

We participate in various multiemployer pension plans under union and industry-wide agreements, which generally provide defined pension benefits to employees covered by collective bargaining agreements. Because of the nature of multiemployer plans, there are risks associated with participation in these plans that differ from single-employer plans. Assets contributed by an employer to a multiemployer plan are not segregated into a separate account and are not restricted to provide benefits only to employees of that contributing employer. In the event another participating employer in a multiemployer plan no longer contributes to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers, including us. In the event of the termination of a multiemployer pension plan or if we withdraw from a multiemployer pension plan, under applicable law we potentially could incur material liabilities.

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 October 31, 2015, these surety bonds and letters of credit totaled approximately $407.1 million and $112.9 million, respectively. Included in the total amount of surety bonds is $6.7 million of bonds with an effective date starting after October 31, 2015.

Guarantees

In some instances, we offer certain clients guaranteed energy savings under certain energy savings contracts. At October 31, 2015 and 2014, total guarantees were $91.1 million and $39.3 million, respectively, and extend through 2030 and 2029, 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 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 liable for any losses incurred by the client due to the failure to perform.

Indemnifications

We are party to a variety of agreements under which we may be obligated to indemnify the other party for certain matters. Primarily, these agreements are standard indemnification arrangements entered into in our ordinary course of business. Pursuant to these arrangements, we may agree to indemnify, hold harmless, and reimburse the indemnified parties for losses suffered or incurred by the indemnified party, generally our clients, in connection with any claims arising out of the services that we provide. We also incur costs to defend lawsuits or settle claims related to these indemnification arrangements, and in most cases these costs are paid from our insurance program. The terms of these indemnification arrangements are generally perpetual. Although we attempt to place limits on this indemnification reasonably related to the size of the contract, the maximum obligation may not be explicitly stated and, as a result, the maximum potential amount of future payments we could be required to make under these arrangements is not determinable.

Our certificate of incorporation and bylaws may require us to indemnify our directors and officers against liabilities that may arise by reason of their status as such and to advance their expenses incurred as a result of any legal proceeding against them as to which they could be indemnified. The overall amount of these obligations cannot be reasonably estimated; however, we believe that any loss under these obligations would not have a material adverse effect on our financial position, results of operations, or cash flows.

Legal Matters

We are a party to a variety of actions, proceedings, and legal, administrative, and other inquiries arising in the normal course of business relating 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 purported class of employees. Litigation outcomes are difficult to predict and are often resolved over long periods of time. Estimating probable losses requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. At October 31, 2015, the total amount accrued for all probable litigation losses where a reasonable estimate of the loss could be made was $8.6 million.

We do not accrue for contingent losses that, in our judgment, are considered to be reasonably possible but not probable. Estimating 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 an estimate can be made is between zero and $6 million, which excludes the individual 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, including, but 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 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 expect that oral argument will not be scheduled before 2016. We believe that the Appeals Court correctly ruled in our favor, and we look forward to presenting our arguments to the California Supreme Court.

Bojorquez v. ABM Industries Incorporated and ABM Janitorial Services–Northern California, Inc., filed on January 13, 2010, in the San Francisco Superior Court (the “Bojorquez case”)

In the previously reported Bojorquez case, the plaintiff brought suit for sexual harassment, retaliation, and failure to prevent harassment and discrimination. On May 17, 2012, a jury awarded the plaintiff approximately $0.8 million in damages. We appealed this decision. On April 11, 2013, the San Francisco Superior Court awarded plaintiff attorneys’ fees in the amount of $2.5 million. Oral argument relating to the appeal took place before the State of California Court of Appeal, First Appellate District (“Court of Appeal”), on May 14, 2015. On June 23, 2015, the Court of Appeal issued an order vacating the submission of the case and requesting supplemental briefing on various issues in the appeal. Pursuant to the Court of Appeal’s June 23, 2015 order, the case was resubmitted for decision on August 13, 2015. Subsequent to the resubmission of the case on August 13, 2015, the parties agreed to mediate the case. The mediation took place on September 10, 2015. The parties have agreed to a settlement in an amount that is not material.

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. The Court scheduled a mandatory settlement conference to take place on January 15, 2016, and trial is set to begin February 16, 2016. We have employment practices liability insurance that we believe would cover us for this case, subject to our negotiated retention.

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 (“SEC”) 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 condition, results of operations, or cash flows.

We are authorized to issue 500,000 shares of preferred stock. None of these preferred shares are issued.

Common Stock

On September 2, 2015, our Board of Directors approved a share repurchase program authorizing us to repurchase shares of our common stock amounting to $200.0 million. This authorization replaced our previous $50.0 million share repurchase program, which had $10.0 million of authorization remaining. As was the case with the previous program, these purchases may take place on the open market or otherwise, and all or part of the repurchases may be made pursuant to the terms of a Rule 10b5-1 plan or in privately negotiated transactions. In addition, such purchases will be made at such times and for such prices as we shall determine at our discretion. Repurchased shares are retired and returned to an authorized but unissued status. The repurchase program may be suspended or discontinued at any time without notice.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]

Share-Based Compensation Plans

12 Months Ended

Oct. 31, 2015

Share-Based Compensation Plans

SHARE-BASED COMPENSATION PLANS

We use various share-based compensation plans to provide incentives for our key employees and directors. Currently, these incentives primarily consist of RSUs, various performance shares, and stock options.

On May 2, 2006, our stockholders approved the 2006 Equity Incentive Plan (the “2006 Equity Plan”). The 2006 Equity Plan is an omnibus plan that provides for a variety of equity and equity-based award vehicles, including stock options, stock appreciation rights, RSUs, performance shares, and other share-based awards. Shares subject to awards that terminate without vesting or exercise are available for future awards under the 2006 Equity Plan. Certain of the awards under the 2006 Equity Plan may qualify as “performance-based” compensation under the IRC.

In 2014, we began issuing TSR-based performance share awards in lieu of stock options. These TSR awards will be earned on the basis of our total shareholder return measured against the total shareholder return of companies in the Standard & Poor’s Small Cap 600 Index (“S&P 600”) over a three-year period.

The 2006 Equity Plan was amended in March 2015 to increase the total shares of common stock authorized for issuance to 11,679,265. At October 31, 2015, 2,311,075 shares of common stock were available for grant for future equity-based compensation awards under the plan. In addition, there are certain plans under which we can no longer issue awards, although awards outstanding under these plans may still vest and be exercised.

We also maintain an employee stock purchase plan, which our stockholders approved on March 9, 2004 (the “2004 Employee Stock Purchase Plan”). The 2004 Employee Stock Purchase Plan was amended in March 2010 to increase the total shares of common stock authorized for issuance to 3,000,000. Effective May 1, 2006, the plan is no longer considered compensatory and the values of the awards are no longer treated as share-based compensation expense. Additionally, as of that date, the purchase price became 95% of the fair value of our common stock price on the last trading day of the month. Employees may designate up to 10% of their compensation for the purchase of stock, subject to a $25,000 annual limit. Employees are required to hold their shares for a minimum of six months from the date of purchase. At October 31, 2015, 241,148 shares remained unissued under the plan.

Income tax benefit	(5.9		)	(6.7		)	(5.0		)
Share-based compensation expense, net of taxes	$	8.3		$	9.1		$	7.8

RSUs and Dividend Equivalent Rights

We award RSUs to eligible employees and our directors (each, a “Grantee”) that entitle the Grantee to receive shares of our common stock as the units vest based on service. In general, the receipt of RSUs is subject to the Grantee’s continuing employment or service as a director, as the case may be. RSUs granted to eligible employees generally vest with respect to 50% of the underlying award on the second and fourth anniversary of the award. RSUs granted to directors vest over three years.

RSUs are credited with dividend equivalent rights that are converted to RSUs at the fair market value of our common stock on the dates the dividend payments are made and are subject to the same terms and conditions as the underlying award.

RSU Activity



	Number of Shares (in millions)		Weighted-Average Grant Date Fair Value per Share
Outstanding at November 1, 2014	1.4		$	23.4
Granted	0.4		29.3
Vested (including 0.1 shares withheld for income taxes)	(0.4	)	22.2
Forfeited	(0.1	)	24.4
Outstanding at October 31, 2015	1.3		25.8

At October 31, 2015, total unrecognized compensation cost, net of estimated forfeitures, related to RSUs was $18.9 million, which is expected to be recognized ratably over a weighted-average vesting period of 1.7 years. In 2015, 2014, and 2013, the weighted-average grant date fair value per share of awards granted was $29.3, $27.8, and $24.9, respectively. In 2015, 2014, and 2013, the total fair value of RSUs that vested was $9.4 million, $5.4 million, and $5.1 million, respectively.

Stock Options

Typically, stock options vest and become exercisable at a rate of 25% per year beginning one year after the date of grant. However terms of stock options can vary, and certain stock options granted on January 10, 2011 will vest on the fifth anniversary of the award. Options typically expire seven years after the date of grant. No stock options were granted in 2015 and 2014. All option grants provide for an option exercise price equal to the closing market value of the common stock on the date of grant.

⁽¹⁾ Amount by which the current market price of our common stock on October 31, 2015 exceeds the exercise price.

⁽²⁾Excludes contractual terms associated with plans prior to the 2006 Equity Plan due to the uncertainty of expiration.

At October 31, 2015, total unrecognized compensation cost, net of estimated forfeitures, related to stock option grants was $0.8 million, which is expected to be recognized ratably over a weighted-average vesting period of 1.6 years. For 2015, 2014, and 2013, the total intrinsic value of stock options exercised was $8.8 million, $3.8 million, and $4.1 million, respectively. In 2013, the weighted-average grant date fair value per share of awards granted was $7.5. In 2015, 2014, and 2013, the total fair value of options that vested was $2.1 million, $1.5 million, and $1.4 million, respectively.

Performance Shares, Including TSR Performance Shares

Performance shares consist of a contingent right to receive shares of our common stock based on performance targets adopted by our Compensation Committee. Performance shares are credited with dividend equivalent rights that will be converted to performance shares at the fair market value of our common stock beginning after the performance targets have been satisfied and are subject to the same terms and conditions as the underlying award.

For certain performance share awards, the number of performance shares that will vest is based on pre-established internal financial performance targets and typically a three-year service and performance period. For TSR awards, the number of performance shares that will vest is based on our total shareholder return relative to the S&P 600 at the time of grant over the respective three-year performance period. Vesting of 0% to 150% of the awards originally granted may occur depending on the respective performance metrics under both award types.

Performance Share Activity



	Number of Shares (in millions)		Weighted-Average Grant Date Fair Value per Share
Outstanding at November 1, 2014	1.1		$	23.9
Granted	0.5		29.8
Vested (including 0.1 shares withheld for income taxes)	(0.2	)	23.0
Performance adjustments	(0.1	)	25.1
Forfeited	(0.2	)	24.3
Outstanding at October 31, 2015	1.1		$	26.4

At October 31, 2015, total unrecognized compensation cost related to performance stock awards was $10.0 million, which is expected to be recognized ratably over a weighted-average vesting period of 1.3 years. Except for TSR performance shares, these costs are based on estimated achievement of performance targets and estimated costs will be reevaluated periodically. For our TSR performance shares, these costs are based on the fair value of awards at the grant date and are recognized on a straight-line basis over the service period of 3 years.

In 2015, 2014, and 2013, the weighted-average grant date fair value per share of awards granted was $29.8, $27.7, and $20.5, respectively. The total fair value of performance shares that vested was $5.0 million in both 2015 and 2014 and $2.2 million in 2013.

Method of Accounting and Our Assumptions

In 2015 and 2014, we used the Monte Carlo simulation valuation technique to estimate the fair value of TSR performance share grants. In the year where stock options were granted, we used the Black-Scholes options-pricing model to estimate the grant date fair value of stock option grants.

Assumptions

*	Not Applicable

(1) For TSR awards valued under the Monte Carlo simulation model, the expected life represents the remaining performance period of the awards. For stock options valued under the Black-Scholes options-pricing model, the expected life is based on observed historical exercise patterns of the previously granted options adjusted to reflect the change in vesting and expiration dates.

(2) For the Monte Carlo simulation model, the expected volatility for each grant is determined based on the historical volatility of our common stock over a period equal to the remaining term of the performance period from the date of grant for all awards. For the Black-Scholes options-pricing model, the expected volatility is based on considerations of implied volatility from publicly traded and quoted options on our common stock and the historical volatility of our common stock.

(3) The dividend yield is based on the historical dividend yield over the expected life of the awards granted.

(4) For the Monte Carlo simulation and Black-Scholes options-pricing models, the risk-free interest rate is based on the continuous compounded yield on U.S. Treasury Constant Maturity Rates with varying remaining terms. For TSR awards valued under the Monte Carlo simulation model, the remaining term is determined over a period of time that is commensurate with the performance period from the grant date. For stock option awards valued under the Black-Scholes options-pricing models, the remaining term is equal to the expected term of the option.

(5) The stock price is the closing price of our common stock on the valuation date.

The effective tax rates on income from continuing operations for 2015 and 2014 were 25.3% and 39.5%, respectively. The effective tax rate for 2015 was lower than the rate for 2014 principally due to: (i) $2.8 million of additional Work Opportunity Tax Credits (“WOTC”) primarily from the retroactive reinstatement of WOTC for calendar year 2014; (ii) $1.9 million of tax benefits for tax deductions on energy efficient government buildings; (iii) $1.6 million of state employment-based tax credits; and (iv) $1.6 million of tax benefits related to the recognition of previously unrecognized tax positions.

The effective tax rate for 2014 was higher than the rate for 2013 due to (i) the expiration of the WOTC as of December 31, 2013 and (ii) the retroactive reinstatement of the WOTC for calendar year 2012, which occurred during the year ended October 31, 2013.

Operating Loss Carryforwards

Operating loss carryforwards totaling $9.1 million at October 31, 2015 are being carried forward in a number of state jurisdictions where we are permitted to use tax operating losses from prior periods to reduce future taxable income. These operating losses will expire between 2016 and 2035. The valuation allowance represents the amount of tax benefits related to state net operating loss carryforwards that are not likely to be realized. We believe the remaining net deferred tax assets are more likely than not to be realizable based on estimates of future taxable income. Changes to the deferred tax asset valuation allowance for 2015, 2014, and 2013 were are as follows:



	Years Ended October 31,

Other, net	0.1			—		0.2
Valuation allowance at the end of the year	$	5.5		$	6.2	$	6.2

During 2015, the decrease in the valuation allowance was primarily due to $0.8 million of state net operating loss carryforwards associated with the sale of the Security business. During 2014, there was no change to the valuation allowance.

Unrecognized Tax Benefits

At October 31, 2015, 2014, and 2013, there was $75.6 million, $78.6 million, and $80.9 million, respectively, of unrecognized tax benefits that if recognized in the future, would impact our effective tax rate. We estimate that a decrease in unrecognized tax benefits of up to approximately $21 million is reasonably possible over the next twelve months due to the resolution of certain tax matters. At October 31, 2015 and 2014, accrued interest and penalties were $3.2 million and $2.2 million, respectively. During 2015, 2014 and 2013, we recognized interest and penalties of $1.0 million, $0.9 million, and $0.2 million, respectively.

Segment Reporting [Abstract]

Segment and Geographic Information

SEGMENT AND GEOGRAPHIC INFORMATION

Segment Information

As discussed in Note 4, “Discontinued Operations,” during the fourth quarter of 2015, we sold our Security business, which was previously reported as a reportable segment. This business is now included within discontinued operations for all periods presented, and we have revised our segment results accordingly. As such, 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.

During 2015, we completed our annual actuarial evaluations for the majority of our casualty insurance programs, which showed unfavorable developments for 2015. Refer to Note 12, “Insurance,” for further details on the results of our actuarial evaluations. As a result of these evaluations, we increased our reserves for 2015 insurance claims by $6.5 million and, consistent with prior periods, we allocated this expense to our operating segments based upon underlying exposures. For years prior to 2015, the analysis showed unfavorable developments in our insurance claims, and as a result, we increased our reserves by $35.9 million. Consistent with prior periods, this adjustment is recorded in Corporate. Additionally, other 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; and


•	direct acquisition costs.

¹Effective in the first quarter of 2015, we reallocated certain costs from our Janitorial segment to our Facility Services and Parking segments to better reflect certain overhead support functions. The impact of these reallocations on the segments was an increase of operating profit to the Janitorial segment and a decrease of operating profit to the Facility Services and Parking segments as follows:

(1) the underlying collateral

(2) credit risks associated with the issuer

(3) contractual maturity

(4) credit enhancements associated with financial insurance guarantees, if any

(5) the possibility of the security being re-financed by the issuer or having a successful auction

OTTI Evaluation Factors

(1) our intent to hold the securities

(2) our assessment that it is not more likely than not that we will be required to sell the securities before recovering our cost basis

(3) expected defaults

(4) available ratings for the securities or the underlying collateral

(5) the rating of the associated guarantor (where applicable)

(6) the nature and value of the underlying collateral expected to service the investment

(7) actual historical performance of the security in servicing its obligations

(8) actuarial experience of the underlying re-insurance arrangement (where applicable), which in certain circumstances may have preferential rights to the underlying collateral

*We depreciate assets under capital leases and leasehold improvements over the shorter of their estimated useful lives or the remaining lease term.

Leases

We record capital leases as an asset and an obligation at an amount that is equal to the present value of the minimum lease payments over the lease term.

Other Intangible Assets

Impairment of Long-Lived Assets

Goodwill

Fair Value of Financial Instruments

Level 1 – Quoted prices for identical assets or liabilities in active markets;

Level 3 – Unobservable inputs for the asset or liability.

See Note 7, “Fair Value of Financial Instruments,” for the fair value hierarchy table and for details on how we measure fair value for financial assets and liabilities.

Other Accrued Liabilities

Insurance Reserves

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. Insurance claim liabilities represent our estimate of retained risks without regard to insurance coverage. We retain a substantial portion of the risk related to certain workers’ compensation and medical claims. Liabilities associated with these losses include estimates of both claims filed and “incurred but not reported” claim costs.

Revenue Recognition



Contract Type		Description
Monthly Fixed-Price		These arrangements are contracts in which the client agrees to pay a fixed fee every month over a specified contract term. A variation of a fixed-price arrangement is a square-foot arrangement, under which monthly billings are based on the actual square footage serviced.
Transaction-Price		These arrangements are agreements in which the clients are billed for each transaction performed on a monthly basis (e.g., wheelchair passengers served, aircrafts cleaned).
Hourly		These arrangements are contracts in which the client is billed a set hourly rate for each labor hour provided.
Cost-Plus		These arrangements are contracts in which the clients reimburse us for the agreed-upon amount of wages and benefits, payroll taxes, insurance charges, and other expenses associated with the contracted work, plus a profit margin.
Tag		Tag work generally consists of supplemental services requested by clients outside of the standard service specification. Examples are cleanup after tenant moves, construction cleanup, flood cleanup, snow removal, and extermination services.
Parking Reimbursement		Under parking reimbursement arrangements, we manage the parking facility for a management fee, and we pass through the revenue and expenses associated with the facility to the owner. Revenues and expenses are reported in equal amounts for costs reimbursed from our managed locations. During 2015, 2014, and 2013, such amounts totaled $305.9 million, $306.1 million, and $302.4 million, respectively.
Fixed-Price Repair and Refurbishment		These arrangements are accounted for under the percentage-of-completion method of accounting, most often based on the cost-to-cost method. Under the percentage-of-completion method, revenues are recognized as the work progresses. The percentage of work completed is determined principally by comparing the actual costs incurred to date with the current estimate of total costs to complete. Under the percentage-of-completion method, recognition of profit is dependent upon the accuracy of a variety of estimates, including engineering progress, achievement of milestones, incentives, labor productivity, and cost estimates. Such estimates are based on various professional judgments made with respect to those factors and are subject to change as each project proceeds and new information becomes available. Revenue and gross profit are adjusted periodically for revisions in estimated total contract costs and values. Estimated losses are recorded when identified.
Franchise		We franchise certain engineering services under the Linc Network and TEGG brands through individual and area franchises. Initial franchise fees are recognized when we have performed substantially all initial services required by the franchise agreement. Royalties are recognized in income as underlying franchisee sales occur. Franchise fees charged to franchisees on a flat rate are recognized as earned. Direct (incremental) costs related to new franchise sales for which the revenue has not been recognized are deferred until the related revenue is recognized. We expense costs related to continuing franchise royalty fees as incurred.

Exit and Disposal Activities

Severance

We recognize severance costs using the provisions of Accounting Standards Codification (“ASC”) ASC 712, Nonretirement Postemployment Benefits, and ASC 420, Exit or Disposal Cost Obligations.

Noncancelable Leases and Contractual Obligations

Other

For other costs associated with exit and disposal activities, we apply the provisions of ASC 420. We recognize an expense at fair value in the period in which the liability is incurred.

Advertising

Advertising costs are expensed as incurred.

Share-Based Compensation

Taxes Collected from Clients and Remitted to Governmental Agencies

We record taxes on client transactions due to governmental agencies as receivables and liabilities on the consolidated balance sheets.

Income Taxes

Our deferred tax assets are reduced by a valuation allowance when, in the opinion of our management, it is more likely than not that all or a portion of the deferred tax assets will not be realized.

Net Income Per Common Share

Contingencies and Litigation

We are a party to a variety of actions, proceedings, and legal, administrative, and other inquiries arising in the normal course of business relating to labor and employment, contracts, personal injury, and other matters. We accrue for loss contingencies when losses become probable and are reasonably estimable. If the reasonable estimate of the loss is a range and no amount within the range is a better estimate, the minimum amount of the range is recorded as a liability. We recognize legal costs as an expense in the period incurred.

[1]	Cash and cash equivalents are stated at nominal value, which equals fair value.
[2]	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 consolidated balance sheets. See Note 12, “Insurance,” for further information.
[3]	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 13, “Line of Credit,” for further information.
[4]	Represents investments held in a Rabbi trust associated with one of our deferred compensation plans, which we include in “Other noncurrent assets” on the accompanying consolidated balance sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. See Note 14, “Employee Benefit Plans,” for further information.
[5]	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. The fair values of the interest rate swap liabilities are included in “Other accrued liabilities” for 2015 and “Other noncurrent liabilities” for 2014, on the accompanying consolidated balance sheets. See Note 13, “Line of Credit,” for more information.
[6]	For investments in auction rate securities, the fair values are based on discounted cash flow valuation models, primarily utilizing unobservable inputs, which we include in “Other investments” on the accompanying consolidated balance sheets. See Note 9, “Auction Rate Securities,” for further information.
[7]	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 consolidated balance sheets.

[1]	For TSR awards valued under the Monte Carlo simulation model, the expected life represents the remaining performance period of the awards. For stock options valued under the Black-Scholes options-pricing model, the expected life is based on observed historical exercise patterns of the previously granted options adjusted to reflect the change in vesting and expiration dates.
[2]	For the Monte Carlo simulation model, the expected volatility for each grant is determined based on the historical volatility of our common stock over a period equal to the remaining term of the performance period from the date of grant for all awards. For the Black-Scholes options-pricing model, the expected volatility is based on considerations of implied volatility from publicly traded and quoted options on our common stock and the historical volatility of our common stock.
[3]	The dividend yield is based on the historical dividend yield over the expected life of the awards granted.
[4]	For the Monte Carlo simulation and Black-Scholes options-pricing models, the risk-free interest rate is based on the continuous compounded yield on U.S. Treasury Constant Maturity Rates with varying remaining terms. For TSR awards valued under the Monte Carlo simulation model, the remaining term is determined over a period of time that is commensurate with the performance period from the grant date. For stock option awards valued under the Black-Scholes options-pricing models, the remaining term is equal to the expected term of the option.
[5]	The stock price is the closing price of our common stock on the valuation date.

[1]	Substantially all of our long-lived assets are related to United States operations.
[2]	Effective in the first quarter of 2015, we reallocated certain costs from our Janitorial segment to our Facility Services and Parking segments to better reflect certain overhead support functions. The impact of these reallocations on the segments was an increase of operating profit to the Janitorial segment and a decrease of operating profit to the Facility Services and Parking segments as follows:
[3]	In connection with the sale of our Security business, certain general corporate expenses that were previously allocated to Security are now allocated back to Corporate expenses and the Janitorial segment. In addition, certain Corporate expenses that were directly related to the operations of the Security business have been allocated to discontinued operations. The net impact of these allocations is as follows:
