The Company and Nature of Operations	THE COMPANY AND NATURE OF OPERATIONS ABM Industries Incorporated, which operates through its subsidiaries (collectively referred to as “ABM,” “we,” “us,” “our,” or the “Company”), is a leading provider of integrated facility services with a mission to make a difference, every person, every day . We are organized into four industry groups and one Technical Solutions segment:

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with (i) United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and (ii) the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments that are necessary for the fair statement of the interim periods presented. Interim results of operations are not necessarily indicative of results for the full year. The Financial Statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) in our Annual Report on Form 10-K for the year ended October 31, 2019 (“Annual Report”). Unless otherwise indicated, all references to years are to our fiscal years, which end on October 31. Impact of the Novel Coronavirus Pandemic A novel strain of coronavirus (“COVID-19”) has resulted in a worldwide health pandemic (the “Pandemic”). To date, the Pandemic has surfaced in nearly all regions around the world and resulted in business slowdowns and shutdowns, as well as global travel restrictions. In these financial statements and related disclosures we have assessed the current impact of the Pandemic on our financial condition, results of operations, and cash flows, as well as our estimates, forecasts, and accounting policies. We have made additional disclosures of these assessments, as necessary. Given the unprecedented nature of this situation, we cannot reasonably estimate the full extent of impact the Pandemic will have on our financial condition, results of operations, or cash flows in the foreseeable future. The ultimate impact of the Pandemic on our company is highly uncertain and will depend on future developments, and such impacts could exist for an extended period of time, even after the Pandemic subsides. The Pandemic continues to create a dynamic client environment, and we are working diligently to ensure our clients’ changing staffing and service needs are met while actively managing direct labor and related personnel costs, including furloughs or reduced hours for certain service employees in markets significantly impacted by business slowdowns and shutdowns. In addition, during the second and third quarters of 2020, we took several human capital management actions to help align our organization operationally and help mitigate the financial impact of the Pandemic on our business, one of which included temporary furloughs for certain staff and management employees. To continue supporting furloughed staff and management employees during the Pandemic, we paid 100% of health insurance premiums during the furlough period for those enrolled in health benefit plans. Most of the furloughed staff and management employees returned to work effective August 1, 2020, and we have not accrued any additional expenses associated with these employees as of and for the three months ended July 31, 2020. Refer to additional discussion regarding the Pandemic and the impact on our business throughout this document, including Note 7, “Fair Value of Financial Instruments,” Note 9, “Credit Facility,” and Item 2., “Management’s Discussion and Analysis of Financial Conditions and Results of Operations.” Rounding We round amounts in the Financial Statements to millions and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding. Discontinued Operations Following the sale of our Security business in 2015, we record all costs associated with this former business in discontinued operations. Such costs generally relate to litigation we retained and insurance reserves. Management Reimbursement Revenue by Segment We operate certain parking facilities under management reimbursement arrangements. Under these arrangements, we manage the parking facilities for management fees and pass through the revenues and expenses associated with the facilities to the owners. These revenues and expenses are reported in equal amounts as costs reimbursed from our managed locations: Three Months Ended July 31, Nine Months Ended July 31, (in millions) 2020 2019 2020 2019 Business & Industry $ 42.6 $ 70.9 $ 178.0 $ 211.2 Aviation 14.8 24.4 61.4 72.0 Total $ 57.4 $ 95.3 $ 239.3 $ 283.2 Recently Adopted Accounting Standards Our significant accounting policies are described in Note 2, “Basis of Presentation and Significant Accounting Policies,” in our Annual Report. There have been no material changes to our significant accounting policies during the nine months ended July 31, 2020, other than as described below. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) . Since the release of ASU 2016-02, the FASB issued the following additional ASUs further updating Topic 842: • In January 2018, ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842 • In July 2018, ASU 2018-10, Codification Improvements to Topic 842 • In July 2018, ASU 2018-11, Leases (Topic 842): Targeted Improvements • In March 2019, ASU 2019-01, Leases (Topic 842): Codification Improvements Topic 842 replaced existing lease accounting guidance and is intended to provide enhanced transparency and comparability by requiring lessees to record most leases on the balance sheet. Under Topic 842, lessees are required to record on the balance sheet right-of-use (“ROU”) assets (the right to use an underlying asset for the lease term) and the corresponding lease liabilities (the obligation to make lease payments arising from the lease). The new guidance requires us to continue classifying leases as either operating or financing, with classification affecting the pattern of expense recognition in the Consolidated Statements of Comprehensive Income (Loss). In addition, the new standard requires enhanced disclosures surrounding the amount, timing, and uncertainty of cash flows arising from leasing arrangements. We adopted Topic 842 on November 1, 2019 on a modified retrospective basis using the optional transition method permitted under ASU 2018-11 and have used this effective date as the initial application date. Comparative prior period financial statements have not been restated and continue to be reported under the accounting standards in effect for those prior periods presented. Upon adoption, we elected the package of transition practical expedients that allowed us to carry forward prior conclusions related to: (i) whether any expired or existing contracts are or contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for existing leases. Additionally, we elected the practical expedient of not separating lease components from non-lease components for all asset classes. We also made an accounting policy election to not record ROU assets or lease liabilities for leases with an initial term of 12 months or less and will recognize payments for such leases in our Consolidated Statements of Comprehensive Income (Loss) on a straight-line basis over the lease term. We did not elect the use of hindsight for determining the reasonably certain lease term. The adoption of Topic 842 had a significant impact on our unaudited Consolidated Balance Sheet, but did not have a significant impact on our unaudited Consolidated Statement of Comprehensive Income (Loss), our unaudited Consolidated Statement of Stockholders’ Equity, our unaudited Consolidated Statement of Cash Flows, our liquidity, or our compliance with the various covenants contained within our credit facility, as further described in Note 9, “Credit Facility.” The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. See Note 4, “Leases,” for additional information on our lease arrangements. The impact of adoption of Topic 842 on our unaudited Consolidated Balance Sheet was as follows: (in millions) Balance at Adjustments Due Balance at ASSETS Right-of-use assets (1) $ — $ 167.5 $ 167.5 LIABILITIES AND STOCKHOLDERS’ EQUITY Current portion of lease liabilities (2) $ — $ 36.3 $ 36.3 Other accrued liabilities (3) 158.2 (3.0) 155.2 Long-term lease liabilities (4) — 154.2 154.2 Other noncurrent liabilities (5) 78.8 (20.0) 58.8 (1) Represents capitalization of operating lease assets and reclassification of prepaid rent, deferred rent, lease exit impairment liabilities, and lease incentives and tenant improvements on operating leases. (2) Represents the recognition of short-term operating lease liabilities. (3) Represents short-term deferred rent reclassified to ROU assets. (4) Represents the recognition of long-term operating lease liabilities. (5) Represents long-term deferred rent, lease incentives and tenant improvements, and lease exit impairment liabilities reclassified to ROU assets. In April 2020, the FASB issued a question and answer document focused on the application of lease accounting guidance to lease concessions provided as a result of the Pandemic (the “Lease Modification Q&A”). The Lease Modification Q&A provides entities with the option to elect to account for lease concessions as though the enforceable rights and obligations existed in the original lease when the total cash flows resulting from the modified lease are substantially similar to the cash flows in the original lease. We have elected this practical expedient for Pandemic-related rent concessions, primarily rent deferrals or rent abatements, and we have elected not to remeasure the related lease liability and ROU asset for those leases. These concessions will be recognized as a reduction of rent expense in the month they occur. This election will continue while these concessions are in effect. Pandemic-related lease concessions were not material for the three and nine months ended July 31, 2020.

Revenue from Contract with Customer [Abstract]
Revenues	REVENUES Disaggregation of Revenues We generate revenues under several types of contracts, as further explained below. The type of contract is determined by the nature of the services provided by each of our major service lines throughout our reportable segments; therefore, we disaggregate revenues from contracts with customers into major service lines. We have determined that disaggregating revenues into these categories best depicts how the nature, amount, timing, and uncertainty of revenues and cash flows are affected by economic factors. Our reportable segments are Business & Industry (“B&I”), Technology and Manufacturing (“T&M”), Education, Aviation, and Technical Solutions, as described in Note 13, “Segment Information.” Three Months Ended July 31, 2020 Nine Months Ended July 31, 2020 (in millions) B&I T&M Education Aviation Technical Total B&I T&M Education Aviation Technical Total Janitorial (1) $ 596.9 $ 197.1 $ 165.7 $ 26.9 $ — $ 986.6 $ 1,786.9 $ 573.1 $ 529.4 $ 91.2 $ — $ 2,980.5 Parking (2) 67.7 8.5 0.2 46.9 — 123.3 290.7 24.0 1.5 203.1 — 519.4 Facility Services (3) 92.2 37.6 22.7 6.3 — 158.8 285.5 113.7 65.7 24.8 — 489.7 Building & Energy Solutions (4) — — — — 119.2 119.2 — — — — 383.5 383.5 Airline Services (5) 0.1 — — 36.2 — 36.3 0.3 — — 220.7 — 221.0 $ 756.9 $ 243.2 $ 188.6 $ 116.4 $ 119.2 $ 1,424.2 $ 2,363.4 $ 710.8 $ 596.6 $ 539.9 $ 383.5 $ 4,594.1 Elimination of inter-segment revenues (30.1) (91.1) Total $ 1,394.1 $ 4,503.0 Three Months Ended July 31, 2019 Nine Months Ended July 31, 2019 (in millions) B&I T&M Education Aviation Technical Total B&I T&M Education Aviation Technical Total Janitorial (1) $ 576.9 $ 184.2 $ 191.4 $ 32.4 $ — $ 985.0 $ 1,738.2 $ 554.4 $ 566.8 $ 94.0 $ — $ 2,953.4 Parking (2) 129.5 6.3 0.7 83.6 — 220.1 383.3 19.6 2.3 253.7 — 658.8 Facility Services (3) 101.4 36.5 23.3 18.5 — 179.6 322.5 113.2 64.6 54.5 — 554.7 Building & Energy Solutions (4) — — — — 165.7 165.7 — — — — 417.7 417.7 Airline Services (5) 0.1 — — 128.8 — 128.9 0.5 0.1 — 363.7 — 364.2 $ 807.9 $ 226.9 $ 215.4 $ 263.3 $ 165.7 $ 1,679.3 $ 2,444.5 $ 687.3 $ 633.6 $ 765.8 $ 417.7 $ 4,948.9 Elimination of inter-segment revenues (31.3) (98.3) Total $ 1,647.9 $ 4,850.6 (1) Janitorial arrangements provide a wide range of essential cleaning services for commercial office buildings, airports and other transportation centers, educational institutions, government buildings, health facilities, industrial buildings, retail stores, and stadiums and arenas. These arrangements are often structured as monthly fixed-price, square-foot, cost-plus, and tag services (work orders) contracts. (2) Parking arrangements provide parking and transportation services for clients at various locations, including airports and other transportation centers, commercial office buildings, educational institutions, health facilities, hotels, and stadiums and arenas. These arrangements are structured as management reimbursement, leased location, and allowance contracts. Certain of these arrangements are considered service concession agreements and are accounted for under the guidance of Topic 853; accordingly, rent expense related to these arrangements is recorded as a reduction of the related parking service revenues. (3) Facility Services arrangements provide onsite mechanical engineering and technical services and solutions relating to a broad range of facilities and infrastructure systems that are designed to extend the useful life of facility fixed assets, improve equipment operating efficiencies, reduce energy consumption, lower overall operational costs for clients, and enhance the sustainability of client locations. These arrangements are generally structured as monthly fixed-price, cost-plus, and tag services contracts. (4) Building & Energy Solutions arrangements provide custom energy solutions, electrical, HVAC, lighting, and other general maintenance and repair services for clients in the public and private sectors and are generally structured as Energy Savings and Fixed-Price Repair and Refurbishment contracts. We also franchise certain operations under franchise agreements relating to our Linc Network and TEGG brands, pursuant to franchise contracts. (5) Airline Services arrangements support airlines and airports with services such as passenger assistance, catering logistics, and airplane cabin maintenance. These arrangements are often structured as monthly fixed-price, cost-plus, transaction price, and hourly contracts. Contract Types We have arrangements under various contract types, as described in Note 2, “Basis of Presentation and Significant Accounting Policies,” in our Annual Report. Certain arrangements involve variable consideration (primarily per transaction fees, reimbursable expenses, and sales-based royalties). We do not estimate the variable consideration for these arrangements; rather, we recognize these variable fees as they are earned. The majority of our contracts include performance obligations that are primarily satisfied over time as we provide the related services. These contract types include: monthly fixed-price; square-foot; cost-plus; tag services; transaction-price; hourly; management reimbursement; leased location; allowance; energy savings contracts; and fixed-price repair and refurbishment contracts, as well as our franchise and royalty fee arrangements. We recognize revenue as the services are performed using a measure of progress that is determined by the contract type. Generally, most of our contracts are cancelable by either party without a substantive penalty, and the majority have a notification period of 30 to 60 days. We primarily account for our performance obligations under the series guidance, using the as-invoiced practical expedient when applicable. We apply the as-invoiced practical expedient to record revenue as the services are provided, given the nature of the services provided and the frequency of billing under the customer contracts. Under this practical expedient, we recognize revenue in an amount that corresponds directly with the value to the customer of our performance completed to date and for which we have the right to invoice the customer. Remaining Performance Obligations At July 31, 2020, performance obligations that were unsatisfied or partially unsatisfied for which we expect to recognize revenue totaled $181.5 million. We expect to recognize revenue on approximately 83% of the remaining performance obligations over the next 12 months, with the remainder recognized thereafter, based on our estimates of project timing. These amounts exclude variable consideration primarily related to: (i) contracts where we have determined that the contract consists of a series of distinct service periods and revenues are based on future performance that cannot be estimated at contract inception; (ii) parking contracts where we and the customer share the gross revenues or operating profit for the location; and (iii) contracts where transaction prices include performance incentives that are based on future performance and therefore cannot be estimated at contract inception. We apply the practical expedient that permits exclusion of information about the remaining performance obligations with original expected durations of one year or less. Contract Balances The timing of revenue recognition, billings, and cash collections results in contract assets and contract liabilities, as further explained below. The timing of revenue recognition may differ from the timing of invoicing to customers. Contract assets primarily consist of billed trade receivables, unbilled trade receivables, and costs incurred in excess of amounts billed. Billed and unbilled trade receivables represent amounts from work completed in which we have an unconditional right to bill our customer. Costs incurred in excess of amounts billed typically arise when the revenue recognized on a project exceeds the amount billed to the customer. These amounts are transferred to billed trade receivables when the rights become unconditional. Contract assets also include the capitalization of incremental costs of obtaining a contract with a customer, primarily commissions. Commissions expense is recognized on a straight-line basis over a weighted average expected customer relationship period. Contract liabilities consist of deferred revenue and advance payments and billings in excess of revenue recognized. We generally classify contract liabilities as current since the related contracts are generally for a period of one year or less. Contract liabilities decrease as we recognize revenue from the satisfaction of the related performance obligation. The following tables present the balances in our contract assets and contract liabilities: (in millions) July 31, 2020 October 31, 2019 Contract assets Billed trade receivables (1) $ 829.3 $ 978.7 Unbilled trade receivables (1) 52.2 56.9 Costs incurred in excess of amounts billed (2) 72.5 72.6 Capitalized commissions (3) 22.6 21.8 (1) Included in trade accounts receivable, net, on the consolidated balance sheets. The fluctuations correlate directly to the execution of new customer contracts and to invoicing and collections from customers in the normal course of business. (2) Fluctuation is primarily due to the timing of payments on our contracts measured using the cost-to-cost method of revenue recognition. (3) Included in other current assets and other noncurrent assets on the consolidated balance sheets. During the nine months ended July 31, 2020, we capitalized $10.6 million of new costs and amortized $9.8 million of previously capitalized costs. There was no impairment loss recorded on the costs capitalized.

Leases [Abstract]
Leases	LEASES We primarily lease office space, parking facilities, warehouses, vehicles, and equipment. We determine if an arrangement is a lease at inception and begin recording lease activity at the commencement date, which is generally the date in which we take possession of or control the physical use of the asset. ROU assets and lease liabilities are recognized based on the present value of lease payments over the lease term with lease expense recognized on a straight-line basis. We use our incremental borrowing rate to determine the present value of future lease payments unless the implicit rate in a lease is readily determinable. Our incremental borrowing rate is the rate of interest we would have to pay to borrow on a collateralized basis over a similar term at an amount equal to the lease payments in a similar economic environment. This incremental borrowing rate is applied to the minimum lease payments within each lease agreement to determine the amounts of our ROU assets and lease liabilities. Our incremental borrowing rate as of November 1, 2019 was utilized for the initial measurement of operating lease liabilities upon adoption of Topic 842, as described in Note 2, “Basis of Presentation and Significant Accounting Policies.” Our lease terms range from 1 to 30 years. Some leases include one or more options to renew, with renewal terms that can extend the lease term. We typically include options to extend the lease in a lease term when it is reasonably certain that we will exercise that option and when doing so is at our sole discretion. Certain equipment and vehicle leases may also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term unless there is a transfer of title or purchase option reasonably certain of exercise. Typically, if we decide to cancel or terminate a lease before the end of its term, we would owe the lessor the remaining lease payments under the term of such lease. Our lease agreements generally do not contain any material residual value guarantees or material restrictive covenants. We may rent or sublease to third parties certain real estate assets that we no longer use. Lease agreements may contain rent escalation clauses, rent holidays, or certain landlord incentives, including tenant improvement allowances. Prior to November 1, 2019, we recognized lease expense related to operating leases on a straight-line basis over the terms of the leases and, accordingly, recorded the difference between cash rent payments and recognition of rent expense as a deferred rent liability or prepaid rent. Landlord-funded leasehold improvements were also recorded as deferred rent liabilities and were amortized as a reduction of rent expense over the noncancelable term of the related operating lease. The ROU assets recognized upon adoption of Topic 842 include cumulative prepaid or accrued rent on the adoption date, unamortized lease incentives, and unamortized initial direct costs initially recognized prior to adoption of Topic 842. Following adoption of Topic 842, ROU assets include amounts for scheduled rent increases and are reduced by lease incentive amounts. Certain of our lease agreements include variable rent payments, consisting primarily of rental payments adjusted periodically for inflation and amounts paid to the lessor based on cost or consumption, such as maintenance and utilities. Certain of our parking arrangements also contain variable rent payments that are a percentage of parking services revenue based on contractual levels. Variable rent lease components are not included in the lease liability. Service concession arrangements within the scope of ASU No. 2017-10, Service Concession Arrangements (Topic 853): Determining the Customer of the Operation Services , are excluded from the scope of Topic 842. Lease costs associated with these arrangements are recorded as a reduction of revenues. See Note 3, “Revenues,” for further discussion.

Restructuring and Related Activities [Abstract]
Restructuring and Related Costs	RESTRUCTURING AND RELATED COSTS We may periodically engage in various restructuring activities intended to drive long-term profitable growth and increase operational efficiency, which can include streamlining and realigning our overall organizational structure and reallocating resources. These activities may result in restructuring costs related to employee severance, other project fees, external support fees, lease exit costs, and asset impairment charges. Recently, our significant restructuring activities have been primarily associated with integrating our acquisition of GCA Services Group (“GCA”) and implementing our 2020 Vision initiative, as described below. GCA Restructuring and Other Initiatives Following the acquisition of GCA, during the first quarter of 2018 we initiated a restructuring program to achieve cost synergies and subsequently incurred expenses primarily related to employee severance, the migration and upgrade of several key technology platforms, and the consolidation of certain real estate leases. Additionally, during 2019 we reorganized our former Healthcare business and incurred immaterial severance expense. In early 2020 we continued our technology-based modernization efforts, including standardizing our financial systems. However, due to the Pandemic, the majority of these projects have been temporarily suspended since the second quarter of 2020. 2020 Vision Restructuring During the fourth quarter of 2015, we initiated a restructuring plan as part of a comprehensive strategy intended to have a positive transformative effect on ABM (the “ 2020 Vision ”). These actions were substantially completed by the end of fiscal 2019 at a cumulative cost of $66.5 million.

(2) Represents restricted deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying unaudited Consolidated Balance Sheets. See Note 8, “Insurance,” for further information. (3) 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 unaudited Consolidated Balance Sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. (4) Represents gross outstanding borrowings under our syndicated line of credit and term loan. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit and term loan approximates the fair value. See Note 9, “Credit Facility,” 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 the London Interbank Offered Rate (“LIBOR”) forward rates at the end of the period. At July 31, 2020 and October 31, 2019, our interest rate swaps are included in “Other noncurrent liabilities” on the accompanying unaudited Consolidated Balance Sheets. See Note 9, “Credit Facility,” for further information. (6) The fair value of investments in auction rate securities is based on discounted cash flow valuation models, primarily utilizing unobservable inputs, including assumptions about the underlying collateral, credit risks associated with the issuer, credit enhancements associated with financial insurance guarantees, and the possibility of the security being re-financed by the issuer or having a successful auction. At October 31, 2019 we held an investment in one auction rate security that had an original principal amount, amortized cost, and fair value of $5.0 million that was included in “Other investments” on the accompanying unaudited Consolidated Balance Sheets. During the first quarter of 2020, this auction rate security was called by the issuer, and we received proceeds for the fair value of this debt instrument of $5.0 million. There were no unrealized gains or losses on this auction rate security included in accumulated other comprehensive loss (“AOCL”). At July 31, 2020 we had no investments in auction rate securities. During the nine months ended July 31, 2020, we had no transfers of assets or liabilities between any of the above hierarchy levels. Non-Financial Assets Measured at Fair Value on a Non-Recurring Basis In addition to assets and liabilities that are measured at fair value on a recurring basis, we are also required to measure certain items at fair value on a non-recurring basis. These assets can include: goodwill; intangible assets; property, plant and equipment; lease-related ROU assets; and long-lived assets that have been reduced to fair value when they are held for sale. If certain triggering events occur, or if an annual impairment test is required, we would evaluate these non-financial assets for impairment. If an impairment were to occur, the asset would be recorded at the estimated fair value, using primarily unobservable Level 3 inputs. During the second quarter of 2020, given the general deterioration in economic and market conditions arising from the Pandemic, we identified a triggering event indicating possible impairment of goodwill and intangible assets, as further described below. We did not identify impairment of our property, plant and equipment, lease-related ROU assets, or long-lived assets. Goodwill Due to the triggering event identified above arising from the impact of the Pandemic, we first performed a qualitative assessment of goodwill to determine whether it was more likely than not that impairment occurred within our goodwill reporting units in the second quarter of 2020. Based on this qualitative assessment, we determined that goodwill impairment was not more likely than not in our goodwill reporting units, other than in Education, Aviation, and our U.K. Technical Solutions business. As a result, we performed an interim quantitative impairment test as of March 31, 2020, on these three goodwill reporting units. For the three goodwill reporting units tested quantitatively, we estimated the fair value using a weighting of fair values derived from an income approach and a market approach, as further described below. Based on the evaluation performed, we determined that goodwill was impaired for each of the three goodwill reporting units evaluated and recognized a non-cash impairment charge totaling $163.8 million ($99.3 million related to Education, $55.5 million related to Aviation, and $9.0 million related to our U.K. Technical Solutions business). The impairment charge is included in “Impairment loss” on our unaudited Consolidated Statements of Comprehensive Income (Loss) for the nine months ended July 31, 2020, and is not tax deductible. During the three months ended July 31, 2020, we did not identify any triggering events, and thus, there were no goodwill impairments recorded during the quarter. The only other changes to the balance of goodwill from October 31, 2019, are translation adjustments. We estimate the fair value of each reporting unit using a combination of the income approach and the market approach. The income approach incorporates the use of a discounted cash flow method in which the estimated future cash flows and terminal value are calculated for each reporting unit and then discounted to present value using an appropriate discount rate. The discount rates utilized in the income approach valuation method are summarized in the table below. Discount Education 10.0% Aviation 10.5% Technical Solutions 11.0% The market approach estimates the fair value of a reporting unit by using market comparables for reasonably similar public companies and a control premium of 15.0%. The valuation of our reporting units requires significant judgment in evaluating recent indicators of market activity and estimated future cash flows, discount rates, and other factors. Our impairment analyses contain inherent uncertainties due to uncontrollable events that could positively or negatively impact anticipated future economic and operating conditions. In making these estimates, the weighted-average cost of capital is utilized to calculate the present value of future cash flows and terminal value. Many variables go into estimating future cash flows, including estimates of our future revenue growth and operating results. When estimating our projected revenue growth and future operating results, we consider industry trends, economic data, and our competitive advantage. If future cash flows or future growth rates vary from what is expected, including those assumptions relating to the duration and severity of the Pandemic, this may reduce the underlying cash flows used to estimate fair values and result in a further decline in fair value, which may trigger future impairment charges. Intangible Assets As a result of the goodwill triggering event described above, we also performed recoverability tests on our intangible assets within each of those segments, primarily customer contracts and relationships, as of March 31, 2020. The recoverability tests were based on forecasts of undiscounted cash flows for each asset group. The results of the recoverability tests indicated certain customer contracts and relationships within our Aviation and U.K. Technical Solutions businesses were not recoverable. As such, we recognized net impairment charges of $5.6 million related to Aviation (consisting of a $13.8 million reduction in the gross carrying amount of the underlying customer relationships less $8.2 million of accumulated amortization) and $3.4 million related to our U.K. Technical Solutions business (consisting of an $8.7 million reduction in the gross carrying amount of the underlying customer relationships less $5.3 million of accumulated amortization). These impairment charges are included in “Impairment

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 to $1.5 million of exposure on a per-occurrence basis, either through deductibles or self-insured retentions. Beyond the retained exposures, we have varying primary policy limits ranging between $1.0 million and $5.0 million per occurrence. To cover general liability and automobile liability losses above these primary limits, we maintain commercial umbrella insurance policies that provide aggregate limits of $200.0 million. Our insurance policies generally cover workers’ compensation losses to the full extent of statutory requirements. Additionally, to cover property damage risks above our retained limits, we maintain policies that provide per occurrence limits of $75.0 million. We are also self-insured for certain employee medical and dental plans. We maintain stop-loss insurance for our self-insured medical plan under which we retain up to $0.5 million of exposure on a per-participant, per-year basis with respect to claims. We maintain our reserves for workers’ compensation, general liability, automobile liability, and property damage insurance claims based upon known trends and events and the actuarial estimates of required reserves considering the most recently completed actuarial reports. We use all available information to develop our best estimate of insurance claims reserves as information is obtained. The results of actuarial reviews are used to estimate our insurance rates and insurance reserves for future periods and to adjust reserves, if appropriate, for prior years. Actuarial Review Performed During Q3 2020 We review our self-insurance liabilities on a regular basis and adjust our accruals accordingly. Actual claims activity or development may vary from our assumptions and estimates, which may result in material losses or gains. As we obtain additional information that affects the assumptions and estimates used in our reserve liability calculations, we adjust our self-insurance rates and reserves for future periods and, if appropriate, adjust our reserves for claims incurred in prior accounting periods. During the third quarter of 2020, we performed a comprehensive actuarial review of the majority of our casualty insurance programs that evaluated changes made to claims reserves and claims payment activity for the period of November 1, 2019 through April 30, 2020 (the “Actuarial Review”). The Actuarial Review was comprehensive in nature and was based on loss development patterns, trend assumptions, and underlying expected loss costs during the period analyzed. Based on the results of the Actuarial Review, at July 31, 2020, we decreased our total reserves for prior periods by $8.5 million. Together with the $6.6 million decrease we recorded during the first half of 2020, the total decrease to our reserves for claims related to prior periods was $15.1 million for the nine months ended July 31, 2020. This compares to a $2.0 million increase in prior period reserves for the nine months ended July 31, 2019. We will continue to assess ongoing developments, which may result in further adjustments to reserves. During the fourth quarter of 2020, we expect to perform an update to our Actuarial Review for our significant insurance programs that will use updated claims data and consider changes in claims development and claims payment activity for the periods analyzed. This review will be abbreviated in nature based on actual versus expected development during the periods analyzed, will rely on the key assumptions used in the Actuarial Review (most notably loss development patterns, trend assumptions, and underlying expected loss costs), and will include claims related to certain previously acquired businesses. This review may lead to further adjustments to our insurance reserves.

Debt Disclosure [Abstract]
Credit Facility	CREDIT FACILITY On September 1, 2017, we refinanced and replaced our then-existing $800.0 million credit facility with a new senior, secured five The Amendment modified the financial covenants under the Credit Facility, including: (i) replacing a maximum total leverage ratio with a maximum total net leverage ratio that varies on a quarterly basis and adjusts to 6.50 to 1.00 by the quarter ending October 31, 2020, and back to 4.00 to 1.00 by the quarter ending October 31, 2022; (ii) modifying the minimum fixed charge coverage ratio on a quarterly basis, which adjusts to 1.25 to 1.00 as of the quarter ending April 30, 2022; and (iii) adding a minimum liquidity (defined in the Amendment as domestic cash plus available revolving loans) of $250.0 million. These financial covenants were effective with the quarter ended April 30, 2020. Our borrowing capacity is subject to, and limited by, compliance with these covenants. The Amendment changed the interest rate, interest margins, and commitment fees applicable to loans and commitments under the Credit Facility. It also added a new anti-cash hoarding mandatory prepayment that requires us to repay outstanding revolving loans or swingline loans if at any time we have in excess of $250 million of cash and cash equivalents on our balance sheet. The Amendment made certain additional changes to the negative covenant restrictions under the Credit Facility, including, subject to certain exceptions, restrictions to our ability to make acquisitions, share repurchases, and other defined restricted payments, depending on our total net leverage ratio. At July 31, 2020, we were in compliance with these covenants. Prior to the Amendment, borrowings under the Credit Facility bore interest at a rate equal to 1-month LIBOR plus a spread that was based upon our leverage ratio. The spread ranged from 1.00% to 2.25% for Eurocurrency loans and 0.00% to 1.25% for base rate loans. We were also charged a commitment fee, which was paid quarterly in arrears and was based on our leverage ratio, that ranged from 0.200% to 0.350% on the average daily unused portion of the revolving line of credit. For purposes of this calculation, irrevocable standby letters of credit, which are issued primarily in conjunction with our insurance programs, and cash borrowings were included as outstanding under the line of credit. Subsequent to the Amendment, borrowings under the Credit Facility bear interest at a rate equal to 1-month LIBOR plus a spread that is based upon our total leverage ratio. The spread ranges from 1.00% to 2.75% for revolving Eurocurrency loans and 0.00% to 1.75% for revolving base rate loans. At July 31, 2020, the weighted average interest rate on our outstanding borrowings was 3.42% . We are also charged a commitment fee, which is paid quarterly in arrears and is based on our total leverage ratio, that ranges from 0.200% to 0.450% on the average daily unused portion of the revolving line of credit. 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 revolving line of credit. The Credit Facility also includes customary events of default, such as: failure to pay principal, interest, or fees when due; failure to comply with covenants; the occurrence of certain material judgments; or a change in control of the Company. If certain events of default occur, including certain cross-defaults, insolvency, change in control, or violation of specific covenants, the lenders can terminate or suspend our access to the Credit Facility, declare all amounts outstanding (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. Total deferred financing costs related to the Credit Facility of $18.7 million, consisting of $13.4 million related to the term loan and $5.2 million related to the line of credit, are being amortized to interest expense over the term of the Credit Facility. We incurred total fees of $4.6 million in conjunction with the Amendment, the majority of which we capitalized in the quarter ended July 31, 2020, and are amortizing over the remaining term of the Credit Facility.

(2) At July 31, 2020, we had borrowing capacity of $563.7 million, reflecting covenant restrictions. Term Loan Maturities During the three and nine months ended July 31, 2020, we made principal payments under the term loan of $30.0 million and $60.0 million, respectively. As of July 31, 2020, the following principal payments are required under the term loan. (in millions) 2020 2021 2022 Debt maturities $ — $ 120.0 $ 560.0 Interest Rate Swaps We enter into interest rate swaps to manage the interest rate risk associated with our floating-rate, LIBOR-based borrowings. Under these arrangements, we typically pay a fixed interest rate in exchange for LIBOR-based variable interest throughout the life of the agreement. We initially report the mark-to-market gain or loss on a derivative as a component of AOCL and subsequently reclassify the gain or loss into earnings when the hedged transactions occur and affect earnings. Interest payables and receivables under the swap agreements are accrued and recorded as adjustments to interest expense. All of our interest rate swaps have been designated and accounted for as cash flow hedges from inception. See Note 7, “Fair Value of Financial Instruments,” regarding the valuation of our interest rate swaps. Notional Amount Fixed Interest Rate Effective Date Maturity Date $ 90.0 million 2.83% November 1, 2018 April 30, 2021 $ 90.0 million 2.84% November 1, 2018 October 31, 2021 $ 130.0 million 2.86% November 1, 2018 April 30, 2022 $ 130.0 million 2.84% November 1, 2018 September 1, 2022 At July 31, 2020 and October 31, 2019, amounts recorded in AOCL for interest rate swaps were a loss of $4.5 million, net of taxes of $1.3 million, and a gain of $2.2 million, net of taxes of $1.2 million, respectively. These amounts included the gain associated with the interest rate swaps we terminated in 2018, which is being amortized to interest expense as interest payments are made over the term of our Credit Facility. During the three and nine months ended July 31, 2020, we amortized $1.2 million, net of taxes of $0.5 million, and $3.6 million, net of taxes of $1.4 million, respectively, of this gain to interest expense. During the three and nine months ended July 31, 2019, we amortized $1.0 million, net of taxes of $0.4 million, and $3.1 million, net of taxes of $1.2 million, respectively. At July 31, 2020, the total amount expected to be reclassified from AOCL to earnings during the next twelve months is a loss of $4.1 million, net of a tax benefit of $1.4 million.

Commitments and Contingencies

Commitments and Contingencies	9 Months Ended

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Letters of Credit and Surety Bonds We use letters of credit and surety bonds to secure certain commitments related to insurance programs and for other purposes. As of July 31, 2020, these letters of credit and surety bonds totaled $153.1 million and $635.0 million, respectively. Guarantees In some instances, we offer clients guaranteed energy savings under certain energy savings contracts. At July 31, 2020, total guarantees were $178.9 million and extend through 2039. We accrue for the estimated cost of guarantees when it is probable that a liability has been incurred and the amount can be reasonably estimated. Historically, we have not incurred any material losses in connection with these guarantees. In connection with an unconsolidated joint venture in which one of our subsidiaries has a 33% ownership interest, that subsidiary and the other joint venture partners have each jointly and severally guaranteed the obligations of the joint venture to perform under certain contracts extending through 2024. Annual revenues relating to the underlying contracts are approximately $30 million. Should the joint venture be unable to perform under these contracts, the joint venture partners would be jointly and severally liable for any losses incurred by the client due to the failure to perform. Sales Tax Audits We collect sales tax from clients and remit those collections to the applicable states. When clients fail to pay their invoices, including the amount of any sales tax that we paid on their behalf, in some cases we are entitled to seek a refund of that amount of sales tax from the applicable state. Sales tax laws and regulations enacted by the various states are subject to interpretation, and our compliance with such laws is routinely subject to audit and review by such states. Audit risk is concentrated in several states, and these states are conducting ongoing audits. The outcomes of ongoing and any future audits and changes in the states’ interpretation of the sales tax laws and regulations could materially adversely impact our results of operations. Legal Matters We are a party to a number of lawsuits, claims, and proceedings incident to the operation of our business, including those pertaining to labor and employment, contracts, personal injury, and other matters, some of which allege substantial monetary damages. Some of these actions may be brought as class actions on behalf of a class or purported class of employees. At July 31, 2020, the total amount accrued for all probable litigation losses where a reasonable estimate of the loss could be made was $6.3 million. Litigation outcomes are difficult to predict and the estimation of probable losses requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. If one or more matters are resolved in a particular period in an amount in excess of, or in a manner different than, what we anticipated, this could have a material adverse effect on our financial position, results of operations, or cash flows. We do not accrue for contingent losses that, in our judgment, are considered to be reasonably possible but not probable. The estimation of reasonably possible losses also requires the analysis of multiple possible outcomes that often depend on judgments about potential actions by third parties. Our management currently estimates the range of loss for all reasonably possible losses for which a reasonable estimate of the loss can be made is between zero and $11 million. 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 lawsuits, claims, and proceedings 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 financial position, results of operations, or cash flows. Certain Legal Proceedings In determining whether to include any particular lawsuit or other proceeding in our disclosure below, we consider both quantitative and qualitative factors. These factors include, but are not limited to: the amount of damages and the nature of any other relief sought in the proceeding; if such damages and other relief are specified, our view of the merits of the claims; whether the action is or purports to be a class action, and our view of the likelihood that a class will be certified by the court; the jurisdiction in which the proceeding is pending; and the potential impact of the proceeding on our reputation. The Consolidated Cases of Bucio and Martinez v. ABM Janitorial Services filed on April 7, 2006, pending in the Superior Court of California, County of San Francisco (the “Bucio case”) The Bucio case is a class action pending in San Francisco Superior Court that alleges we failed to provide legally required meal periods and make additional premium payments for such meal periods, pay split shift premiums when owed, and reimburse janitors for travel expenses. There is also a claim for penalties under the California Labor Code Private Attorneys General Act (“PAGA”). 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 appealed the class certification issues. The trial court stayed the underlying lawsuit pending the decision in the appeal. The Court of Appeal of the State of California, First Appellate District (the “Court of Appeal”), heard oral arguments on November 7, 2017. On December 11, 2017, the Court of Appeal reversed the trial court’s order denying class certification and remanded the matter for certification of a meal period, travel expense reimbursement, and split shift class. The case was remitted to the trial court for further proceedings on class certification, discovery, dispositive motions, and trial. On September 20, 2018, the trial court entered an order defining four certified subclasses of janitors who were employed by the legacy ABM janitorial companies in California at any time between April 7, 2002 and April 30, 2013, on claims based on alleged previous automatic deduction practices for meal breaks, unpaid meal premiums, unpaid split shift premiums, and unreimbursed business expenses, such as mileage reimbursement for use of personal vehicles to travel between worksites. On February 1, 2019, the trial court held that the discovery related to

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our quarterly tax provision is calculated using an estimated annual tax rate that is adjusted for discrete items occurring during the period to arrive at our effective tax rate. During the three and nine months ended July 31, 2020, we had effective tax rates of 29.9% and (444.6)%, respectively. The effective tax rate for the nine months ended July 31, 2020, excluding a nondeductible impairment loss of $163.8 million, was 28.0%. For the three and nine months ended July 31, 2020, the provisions for taxes were $24.0 million and $43.2 million, respectively. During the three and nine months ended July 31, 2019, we had effective tax rates of 18.9% and 24.5%, respectively, resulting in provisions for taxes of $8.5 million and $25.8 million, respectively. Our effective tax rate for the three months ended July 31, 2020, was impacted by a discrete benefit of $0.8 million related to energy efficiency. Our effective tax rate for the three months ended July 31, 2019, was impacted by the following discrete items: a $2.0 million benefit from an expiring statute of limitations and a $0.5 million benefit from certain credits. Our effective tax rate for the nine months ended July 31, 2020, was impacted by the following discrete items: a $1.9 million tax provision related to the Work Opportunity Tax Credit (“WOTC”) and a $1.2 million benefit related to energy efficiency. Our effective tax rate for the nine months ended July 31, 2019, was impacted by the following discrete items: a $2.0 million benefit from an expiring statute of limitations; a $1.4 million provision for reserves; a $1.3 million provision related to WOTC; and a $1.1 million benefit from the vesting of share-based compensation awards. In response to COVID-19, Congress enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) on March 27, 2020. The CARES Act provides various stimulus measures, including several income tax and payroll tax provisions. Among the payroll tax provisions is the creation of a refundable credit for employee retention and the deferral of certain payroll tax remittances through December 31, 2020, to future years (with 50% of the deferred amount due by December 31, 2021, and the remaining 50% due by December 31, 2022). We evaluated the impact of business tax provisions in the CARES Act. The impact of the income tax provisions was not

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended
	Jul. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited consolidated financial statements have been prepared in accordance with (i) United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and (ii) the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of our management, our unaudited consolidated financial statements and accompanying notes (the “Financial Statements”) include all normal recurring adjustments that are necessary for the fair statement of the interim periods presented. Interim results of operations are not necessarily indicative of results for the full year. The Financial Statements should be read in conjunction with our audited consolidated financial statements (and notes thereto) in our Annual Report on Form 10-K for the year ended October 31, 2019 (“Annual Report”). Unless otherwise indicated, all references to years are to our fiscal years, which end on October 31.
Discontinued Operations	Following the sale of our Security business in 2015, we record all costs associated with this former business in discontinued operations. Such costs generally relate to litigation we retained and insurance reserves.
Management Reimbursement Revenue by Segment and Contracts with Customers	We operate certain parking facilities under management reimbursement arrangements. Under these arrangements, we manage the parking facilities for management fees and pass through the revenues and expenses associated with the facilities to the owners.
Recently Adopted Accounting Standards	Our significant accounting policies are described in Note 2, “Basis of Presentation and Significant Accounting Policies,” in our Annual Report. There have been no material changes to our significant accounting policies during the nine months ended July 31, 2020, other than as described below. Leases In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) . Since the release of ASU 2016-02, the FASB issued the following additional ASUs further updating Topic 842: • In January 2018, ASU 2018-01, Land Easement Practical Expedient for Transition to Topic 842 • In July 2018, ASU 2018-10, Codification Improvements to Topic 842 • In July 2018, ASU 2018-11, Leases (Topic 842): Targeted Improvements • In March 2019, ASU 2019-01, Leases (Topic 842): Codification Improvements Topic 842 replaced existing lease accounting guidance and is intended to provide enhanced transparency and comparability by requiring lessees to record most leases on the balance sheet. Under Topic 842, lessees are required to record on the balance sheet right-of-use (“ROU”) assets (the right to use an underlying asset for the lease term) and the corresponding lease liabilities (the obligation to make lease payments arising from the lease). The new guidance requires us to continue classifying leases as either operating or financing, with classification affecting the pattern of expense recognition in the Consolidated Statements of Comprehensive Income (Loss). In addition, the new standard requires enhanced disclosures surrounding the amount, timing, and uncertainty of cash flows arising from leasing arrangements. We adopted Topic 842 on November 1, 2019 on a modified retrospective basis using the optional transition method permitted under ASU 2018-11 and have used this effective date as the initial application date. Comparative prior period financial statements have not been restated and continue to be reported under the accounting standards in effect for those prior periods presented. Upon adoption, we elected the package of transition practical expedients that allowed us to carry forward prior conclusions related to: (i) whether any expired or existing contracts are or contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for existing leases. Additionally, we elected the practical expedient of not separating lease components from non-lease components for all asset classes. We also made an accounting policy election to not record ROU assets or lease liabilities for leases with an initial term of 12 months or less and will recognize payments for such leases in our Consolidated Statements of Comprehensive Income (Loss) on a straight-line basis over the lease term. We did not elect the use of hindsight for determining the reasonably certain lease term. The adoption of Topic 842 had a significant impact on our unaudited Consolidated Balance Sheet, but did not have a significant impact on our unaudited Consolidated Statement of Comprehensive Income (Loss), our unaudited Consolidated Statement of Stockholders’ Equity, our unaudited Consolidated Statement of Cash Flows, our liquidity, or our compliance with the various covenants contained within our credit facility, as further described in Note 9, “Credit Facility.” The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. See Note 4, “Leases,” for additional information on our lease arrangements. The impact of adoption of Topic 842 on our unaudited Consolidated Balance Sheet was as follows: (in millions) Balance at Adjustments Due Balance at ASSETS Right-of-use assets (1) $ — $ 167.5 $ 167.5 LIABILITIES AND STOCKHOLDERS’ EQUITY Current portion of lease liabilities (2) $ — $ 36.3 $ 36.3 Other accrued liabilities (3) 158.2 (3.0) 155.2 Long-term lease liabilities (4) — 154.2 154.2 Other noncurrent liabilities (5) 78.8 (20.0) 58.8 (1) Represents capitalization of operating lease assets and reclassification of prepaid rent, deferred rent, lease exit impairment liabilities, and lease incentives and tenant improvements on operating leases. (2) Represents the recognition of short-term operating lease liabilities. (3) Represents short-term deferred rent reclassified to ROU assets. (4) Represents the recognition of long-term operating lease liabilities. (5) Represents long-term deferred rent, lease incentives and tenant improvements, and lease exit impairment liabilities reclassified to ROU assets. In April 2020, the FASB issued a question and answer document focused on the application of lease accounting guidance to lease concessions provided as a result of the Pandemic (the “Lease Modification Q&A”). The Lease Modification Q&A provides entities with the option to elect to account for lease concessions as though the enforceable rights and obligations existed in the original lease when the total cash flows resulting from the modified lease are substantially similar to the cash flows in the original lease. We have elected this practical expedient for Pandemic-related rent concessions, primarily rent deferrals or rent abatements, and we have elected not to remeasure the related lease liability and ROU asset for those leases. These concessions will be recognized as a reduction of rent expense in the month they occur. This election will continue while these concessions are in effect. Pandemic-related lease concessions were not material for the three and nine months ended July 31, 2020.
Revenues	We have arrangements under various contract types, as described in Note 2, “Basis of Presentation and Significant Accounting Policies,” in our Annual Report. Certain arrangements involve variable consideration (primarily per transaction fees, reimbursable expenses, and sales-based royalties). We do not estimate the variable consideration for these arrangements; rather, we recognize these variable fees as they are earned. The majority of our contracts include performance obligations that are primarily satisfied over time as we provide the related services. These contract types include: monthly fixed-price; square-foot; cost-plus; tag services; transaction-price; hourly; management reimbursement; leased location; allowance; energy savings contracts; and fixed-price repair and refurbishment contracts, as well as our franchise and royalty fee arrangements. We recognize revenue as the services are performed using a measure of progress that is determined by the contract type. Generally, most of our contracts are cancelable by either party without a substantive penalty, and the majority have a notification period of 30 to 60 days.

These arrangements are often structured as monthly fixed-price, square-foot, cost-plus, and tag services (work orders) contracts. (2) Parking arrangements provide parking and transportation services for clients at various locations, including airports and other transportation centers, commercial office buildings, educational institutions, health facilities, hotels, and stadiums and arenas. These arrangements are structured as management reimbursement, leased location, and allowance contracts. Certain of these arrangements are considered service concession agreements and are accounted for under the guidance of Topic 853; accordingly, rent expense related to these arrangements is recorded as a reduction of the related parking service revenues. (3) Facility Services arrangements provide onsite mechanical engineering and technical services and solutions relating to a broad range of facilities and infrastructure systems that are designed to extend the useful life of facility fixed assets, improve equipment operating efficiencies, reduce energy consumption, lower overall operational costs for clients, and enhance the sustainability of client locations. These arrangements are generally structured as monthly fixed-price, cost-plus, and tag services contracts. (4) Building & Energy Solutions arrangements provide custom energy solutions, electrical, HVAC, lighting, and other general maintenance and repair services for clients in the public and private sectors and are generally structured as Energy Savings and Fixed-Price Repair and Refurbishment contracts. We also franchise certain operations under franchise agreements relating to our Linc Network and TEGG brands, pursuant to franchise contracts. (5) Airline Services arrangements support airlines and airports with services such as passenger assistance, catering logistics, and airplane cabin maintenance. These arrangements are often structured as monthly fixed-price, cost-plus, transaction price, and hourly contracts.

(2) Represents restricted deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying unaudited Consolidated Balance Sheets. See Note 8, “Insurance,” for further information. (3) 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 unaudited Consolidated Balance Sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. (4) Represents gross outstanding borrowings under our syndicated line of credit and term loan. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit and term loan approximates the fair value. See Note 9, “Credit Facility,” 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 the London Interbank Offered Rate (“LIBOR”) forward rates at the end of the period. At July 31, 2020 and October 31, 2019, our interest rate swaps are included in “Other noncurrent liabilities” on the accompanying unaudited Consolidated Balance Sheets. See Note 9, “Credit Facility,” for further information. (6) The fair value of investments in auction rate securities is based on discounted cash flow valuation models, primarily utilizing unobservable inputs, including assumptions about the underlying collateral, credit risks associated with the issuer, credit enhancements associated with financial insurance guarantees, and the possibility of the security being re-financed by the issuer or having a successful auction. At October 31, 2019 we held an investment in one auction rate security that had an original principal amount, amortized cost, and fair value of $5.0 million that was included in “Other investments” on the accompanying unaudited Consolidated Balance Sheets. During the first quarter of 2020, this auction rate security was called by the issuer, and we received proceeds for the fair value of this debt instrument of $5.0 million. There were no unrealized gains or losses on this auction rate security included in accumulated other comprehensive loss (“AOCL”). At July 31, 2020 we had no investments in auction rate securities.
