New Accounting Standards

Accounting Policies [Abstract]
New Accounting Standards	2. New Accounting Standards In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases (Topic 842) (Accounting Standards Codification (ASC) 840) The new standard provided a number of optional practical expedients for transition. The Company elected to adopt the standard using the package of practical expedients, which allowed the Company not to reassess prior conclusions about lease identification, lease classification and initial direct costs. In addition, the new guidance provides practical expedients for an entity’s ongoing lessee accounting. The Company has elected not to separate payments for lease components from payments for non-lease components for any classes of assets. The Company has elected the short-term lease recognition exemption for all leases that qualify, which means ROU assets and lease liabilities are not recognized for leases with an initial term of twelve months or less. The most significant quantitative effect of adoption relates to the recognition of ROU assets and lease liabilities on the balance sheet for operating leases. The adoption did not have a material impact on the Company’s results of operations or cash flows. The cumulative effect of initially applying the new leasing guidance to the Company’s Condensed Consolidated Financial Statements as of October 1, 2019 was as follows (in millions): Balance as of September 30, 2019 Cumulative Impact from Adopting New Lease Standard Balance as of October 1, 2019 Assets Other current assets $ 78.9 $ (0.5 ) $ 78.4 Total current assets 3,408.3 (0.5 ) 3,407.8 Other long-term assets 156.4 179.5 335.9 Total assets 5,566.3 179.0 5,745.3 Liabilities and Shareholders’ Equity Other current liabilities $ 307.3 $ 46.4 $ 353.7 Total current liabilities 1,741.9 46.4 1,788.3 Other long-term liabilities 405.6 132.6 538.2 Total liabilities and shareholders’ equity 5,566.3 179.0 5,745.3 See Note 12 of the Notes to Condensed Consolidated Financial Statements for additional information regarding the Company’s accounting for leases. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) , Simplifying the Accounting for Income Taxes . The standard simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 such as recognizing deferred taxes for equity investments, the incremental approach to performing intraperiod tax allocation and calculating income taxes in interim periods . The standard also simplif ies accounting for income taxes under U.S. GAAP by clarifying and amending existing guidance , including the recognition of deferred taxes for goodwill , the a llocati on of taxes to members of a consolidated group and requiring that an entity reflect the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date . The Company will be required to adopt ASU 2019-12 as of October 1, 2021. Early adoption is permitted. The Company is currently evaluating the impact of 2019-12 on the Company’s consolidated financial statements.

Revenue Recognition

Sales And Revenue Recognition [Abstract]
Revenue Recognition	3. Revenue Recognition The Defense segment recognizes revenue on its performance obligations that are satisfied over time by measuring progress using the cost-to-cost method of percentage-of-completion because it best depicts the transfer of control to the customer. Under the cost-to-cost method of percentage-of-completion, the Defense segment measures progress based on the ratio of costs incurred to date to total estimated costs for the performance obligation. The Company recognizes changes in estimated sales or costs and the resulting profit or loss on a cumulative basis. Cumulative estimate-at-completion adjustments represent the cumulative effect of the changes on prior periods. If a loss is expected on a performance obligation, the complete estimated loss is recorded in the period in which the loss is identified. There is significant judgment involved in estimating sales and costs within the Defense segment. Each contract is evaluated at contract inception to identify risks and estimate revenue and costs. In performing this evaluation, the Defense segment considers risks of contract performance such as technical requirements, schedule, duration and key contract dependencies. These considerations are then factored into the Company’s estimated revenue and costs. Preliminary contract estimates are subject to change throughout the duration of the contract as additional information becomes available that impacts risks and estimated revenue and costs. In addition, as contract modifications (e.g., new orders) are received, the additional units are factored into the overall contract estimate of costs and transaction price. Contract adjustments resulted in changes within the Defense segment as follows (in millions, except for per share amounts): Three Months Ended June 30, Nine Months Ended June 30, 2020 2019 2020 2019 Net sales $ 4.5 $ (0.4 ) $ 28.2 $ 55.7 Operating income 1.6 (10.5 ) 15.2 37.6 Net income 1.2 (8.2 ) 11.6 28.9 Diluted earnings per share 0.02 (0.12 ) 0.17 0.41 Disaggregation of Revenue The table below presents consolidated net sales disaggregated by segment and timing of revenue recognition (in millions): Three Months Ended June 30, 2020 Access Equipment Defense Fire & Emergency Commercial Corporate and intersegment eliminations Total Point in time $ 472.1 $ 0.4 $ 298.7 $ 153.5 $ (13.2 ) $ 911.5 Over time 15.9 547.1 12.0 94.2 0.1 669.3 $ 488.0 $ 547.5 $ 310.7 $ 247.7 $ (13.1 ) $ 1,580.8 Three Months Ended June 30, 2019 Access Equipment Defense Fire & Emergency Commercial Corporate and intersegment eliminations Total Point in time $ 1,231.1 $ 0.5 $ 319.9 $ 176.5 $ (4.6 ) $ 1,723.4 Over time 18.0 510.6 21.1 119.6 — 669.3 $ 1,249.1 $ 511.1 $ 341.0 $ 296.1 $ (4.6 ) $ 2,392.7 Nine Months Ended June 30, 2020 Access Equipment Defense Fire & Emergency Commercial Corporate and intersegment eliminations Total Point in time $ 1,838.2 $ 1.3 $ 793.6 $ 391.0 $ (20.6 ) $ 3,003.5 Over time 60.7 1,654.3 35.1 317.6 1.4 2,069.1 $ 1,898.9 $ 1,655.6 $ 828.7 $ 708.6 $ (19.2 ) $ 5,072.6 Nine Months Ended June 30, 2019 Access Equipment Defense Fire & Emergency Commercial Corporate and intersegment eliminations Total Point in time $ 3,007.8 $ 2.2 $ 885.1 $ 445.8 $ (14.7 ) $ 4,326.2 Over time 55.4 1,459.7 34.6 310.4 — 1,860.1 $ 3,063.2 $ 1,461.9 $ 919.7 $ 756.2 $ (14.7 ) $ 6,186.3 See Note 21 of the Notes to Condensed Consolidated Financial Statements for further disaggregated sales information. Contract Assets and Contract Liabilities The Company is generally entitled to bill its customers upon satisfaction of its performance obligations, with the exception of its long-term contracts in the Defense segment which typically allow for billing upon acceptance of the finished good, advance payments from customers primarily within the Fire & Emergency segment and extended warranties that are usually billed in advance of the warranty coverage period. Customer payment is usually received shortly after billing and payment terms generally do not exceed one year. With the exception of the Fire & Emergency segment, the Company’s contracts typically do not contain a significant financing component. In the Fire & Emergency segment, customers earn interest on customer advances at a rate determined in a separate financing transaction between the Fire & Emergency segment and the customer at contract inception. Interest due on customer advances of $4.5 million and $11.7 million was recorded in “Interest expense” in the Condensed Consolidated Statements of Income for the three and nine months ended June 30, 2020, respectively, and $3.9 million and $11.2 million for the three and nine months ended June 30, 2019, respectively. The timing of billing does not always match the timing of revenue recognition. In instances where a customer pays consideration in advance or when the Company is entitled to bill a customer in advance of recognizing the related revenue, the Company records a contract liability within “Customer advances”, “Other current liabilities” or “Other long-term liabilities” in the Condensed Consolidated Balance Sheet. Total contract liabilities were $628.8 million as of June 30, 2020 , of which $518.4 million , $60.1 million and $50.3 million was included in “Customer advances”, “Other current liabilities” and “Other long-term liabilities”, respectively. Total contract liabilities were $512.5 million as of September 30 , 201 9 , of which $382.0 million , $78.2 million and $52.3 million was included in “Customer advances”, “Other current liabilities” and “Other long-term liabilities”, respectively. The Company reduces contract liabilities when revenue is recognized. The Company recognized $102.2 million and $392.8 million of revenue that was recorded as a contract liability as of the beginning of the period during the three and nine months ended June 30, 2020 . The Company recognized $248.1 million and $721.5 million of revenue that was recorded as a contract liability as of the beginning of the period during the three and nine months ended June 3 0 , 2019 . In instances where the Company recognizes revenue prior to having an unconditional right to payment, the Company records a contract asset within “Unbilled receivables, net” in the Condensed Consolidated Balance Sheet. The Company reduces contract assets when the Company has an unconditional right to payment. The Company periodically assesses its contract assets for impairment. Contract assets and liabilities are determined on a net basis for each contract. The Company did not record any impairment losses on contract assets during the three and nine months ended June 30, 2020 and 2019, respectively. See Note 8 of the Notes to Condensed Consolidated Financial Statements for additional information on the Company’s receivable balances. The Company offers a variety of service-type warranties, including optionally priced extended warranty programs. Outstanding balances related to service-type warranties are included within contract liabilities disclosed above.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	4. Stock-Based Compensation In February 2017, the Company’s shareholders approved the 2017 Incentive Stock and Awards Plan (the “2017 Stock Plan”). The 2017 Stock Plan replaced the 2009 Incentive Stock and Awards Plan (as amended, the “2009 Stock Plan”). While no new awards will be granted under the 2009 Stock Plan, awards previously made under that plan that were outstanding as of the approval date of the 2017 Stock Plan will remain outstanding and continue to be governed by the provisions of that plan. At June 30, 2020, the Company had reserved 5,780,306 shares of Common Stock available for issuance to provide for the exercise of outstanding stock options and the issuance of Common Stock under incentive compensation awards, including awards issued prior to the effective date of the 2017 Stock Plan. The Company recognizes stock-based compensation expense over the requisite service period for vesting of an award, or to an employee’s eligible retirement date, if earlier and applicable. Total stock-based compensation expense, including cash-based liability awards, for the three and nine months ended June 30, 2020 was $7.0 million ($6.1 million net of tax) and $24.9 million ($21.8 million net of tax), respectively.

Income Tax Disclosure [Abstract]
Income Taxes	6. Income Taxes The Company recorded income tax expense of $28.0 million for the three months ended June 30, 2020, or 25.8% of pre-tax income, compared to $53.7 million, or 21.8% of pre-tax income, for the three months ended June 30, 2019. For the three months ended June 30, 2020 a discrete benefit related to the fiscal 2019 federal provision-to-return adjustment of $2.0 million was largely offset by discrete charges related to changes in uncertain tax position reserves. Results for the three months ended June 30, 2019 were favorably impacted by $1.2 million of net discrete tax benefits, including a $0.4 million benefit related to the fiscal 2018 federal provision-to-return adjustment, a $0.4 million benefit for the expiration of foreign tax statutes of limitations and a $0.3 million benefit related to employee share-based payments. The Company recorded income tax expense of $87.0 million for the nine months ended June 30, 2020, or 27.8% of pre-tax income, compared to $129.6 million, or 23.2% of pre-tax income, for the nine months ended June 30, 2019. Results for the nine months ended June 30, 2020 were unfavorably impacted by $10.1 million of net discrete tax charges, including a $11.4 million charge related to a valuation allowance recorded against certain foreign net deferred tax assets in Europe, a $2.6 million benefit related to employee stock-based compensation payments, a $2.0 million benefit related to the fiscal 2019 federal provision-to-return adjustment and $1.9 million of charges related to changes in uncertain tax position reserves. Results for the nine months ended June 30, 2019 were unfavorably impacted by $5.9 million of net discrete tax charges, including $4.6 million of tax charges related to uncertain tax position reserves, a $1.5 million tax benefit related to receiving tax incentives in a foreign jurisdiction, a $1.3 million charge related to remeasuring deferred tax assets and liabilities in response to a corporate tax rate change in a foreign jurisdiction, a $1.4 million tax benefit related to employee share-based payments and a $1.9 million charge related to adjustments to the repatriation tax required under the U.S. Tax Cuts and Jobs Act. The Company’s liability for gross unrecognized tax benefits, excluding related interest and penalties, was $100.5 million and $97.3 million as of June 30, 2020 and September 30, 2019, respectively. As of June 30, 2020, net unrecognized tax benefits, excluding interest and penalties, of $21.4 million would affect the Company’s net income if recognized. The Company recognizes accrued interest and penalties, if any, related to unrecognized tax benefits in the “Provision for income taxes” in the Condensed Consolidated Statements of Income. During the nine months ended June 30, 2020 and 2019, the Company recognized expense of $1.0 million and $0.6 million, respectively, related to interest and penalties. At June 30, 2020, the Company had accruals for the payment of interest and penalties of $5.4 million. During the next twelve months, it is reasonably possible that federal, state and foreign tax audit resolutions could reduce net unrecognized tax benefits by approximately $9.0 million because the Company’s tax positions are sustained on audit, the Company agrees to their disallowance or the statutes of limitations close.

Leases [Abstract]
Leases	1 2 . Leases The Company leases certain real estate, information technology equipment, warehouse equipment, vehicles and other equipment almost exclusively through operating leases. The Company determines whether an arrangement contains a lease at inception. A lease liability and corresponding ROU asset are recognized for qualifying leased assets based on the present value of fixed and certain index based lease payments at lease commencement. Variable payments, which are generally determined based on the usage rate of the underlying asset, are excluded from the present value of lease payments and are recognized in the period in which the payment is made. To determine the present value of lease payments, the Company uses the stated interest rate in the lease, when available, or more commonly a secured incremental borrowing rate that reflects risk, term and economic environment in which the lease is denominated. The incremental borrowing rate is determined using a portfolio approach based on the current rate of interest that the Company would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term. The Company has elected not to separate payments for lease components from payments for non-lease components in contracts that contain both components. Lease agreements may include options to extend or terminate the lease. Those options that are reasonably certain of exercise at lease commencement have been included in the term of the lease used to recognize the ROU assets and lease liabilities. The lease term of the Company’s real estate and equipment leases extend up to 29 years and 16 years, respectively. The Company has elected not to recognize ROU assets or lease liabilities for leases with a term of twelve months or less. Expense is recognized on a straight-line basis over the lease term for operating leases. The Company’s finance leases are not significant. The components of lease costs were as follows (in millions): Three Months Ended June 30, 2020 Nine Months Ended June 30, 2020 Operating lease cost $ 13.6 $ 42.4 Variable lease cost 12.0 33.8 Short-term lease cost 1.7 3.5 Supplemental information related to operating leases was as follows (in millions): Balance Sheet Classification June 30, 2020 Operating leases Lease ROU assets Other long-term assets $ 158.2 Current lease liabilities Other current liabilities 45.5 Long-term lease liabilities Other long-term liabilities 116.0 Weighted average remaining lease term 6 years Weighted average discount rates 2.9 % The table below presents the ROU asset balance for operating leases disaggregated by segment and type of lease (in millions): June 30, 2020 Access Equipment Defense Fire & Emergency Commercial Corporate and intersegment eliminations Total Real estate leases $ 66.3 $ 28.9 $ 6.9 $ 18.5 $ 7.2 $ 127.8 Equipment leases 7.8 4.6 2.4 2.5 13.1 30.4 $ 74.1 $ 33.5 $ 9.3 $ 21.0 $ 20.3 $ 158.2 Maturities of operating lease liabilities at June 30, 2020 and minimum payments for operating leases (under ASC 842) having initial or remaining non-cancelable terms in excess of one year were as follows (in millions) : Amounts due in Remaining three months of 2020 $ 13.5 2021 46.0 2022 34.0 2023 23.1 2024 15.7 2025 11.2 Thereafter 31.5 Total lease payments 175.0 Less: imputed interest (13.5 ) Present value of lease liability $ 161.5 At September 30, 2019, future minimum operating lease payments (under ASC 840) were as follows (in millions): Amounts due in 2020 $ 34.0 2021 26.7 2022 15.9 2023 11.3 2024 7.1 Thereafter 11.7

The Credit Agreement provides for (i) an unsecured revolving credit facility (the “Revolving Credit Facility”) that matures in April 2023 with an initial maximum aggregate amount of availability of $850 million and (ii) an unsecured $325 million term loan (the “Term Loan”) due in quarterly principal installments of $4.1 million commencing September 30, 2019 with a balloon payment of $264.1 million due at maturity in April 2023. The Company has prepaid all required quarterly principal installments and $39.1 million of the balloon payment on the Term Loan. At June 30, 2020, outstanding letters of credit of $57.9 million reduced available capacity under the Revolving Credit Facility to $792.1 million. Under the Credit Agreement, the Company is obligated to pay (i) an unused commitment fee ranging from 0.125% to 0.275% per annum of the average daily unused portion of the aggregate revolving credit commitments under the Credit Agreement and (ii) a fee ranging from 0.563% to 1.75% per annum of the maximum amount available to be drawn for each letter of credit issued and outstanding under the Credit Agreement. Borrowings under the Credit Agreement bear interest at a variable rate equal to (i) LIBOR plus a specified margin, which may be adjusted upward or downward depending on whether certain criteria are satisfied, or (ii) for dollar-denominated loans only, the base rate (which is the highest of (a) the administrative agent’s prime rate, (b) the federal funds rate plus 0.50% or (c) the sum of 1% plus one-month LIBOR) plus a specified margin, which may be adjusted upward or downward depending on whether certain criteria are satisfied. At June 30, 2020, the interest spread on the Revolving Credit Facility and Term Loan was 125 basis points. The weighted-average interest rate on borrowings outstanding under the Term Loan at June 30, 2020 was 1.43%. The Credit Agreement contains various restrictions and covenants, including requirements that the Company maintain certain financial ratios at prescribed levels and restrictions, subject to certain exceptions, on the ability of the Company and certain of its subsidiaries to consolidate or merge, create liens, incur additional indebtedness, and dispose of substantially all assets. The Credit Agreement contains the following financial covenants: • Leverage Ratio: A maximum leverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated indebtedness to consolidated net income before interest, taxes, depreciation, amortization, non-cash charges and certain other items (EBITDA)) as of the last day of any fiscal quarter of 3.75 to 1.00. • Interest Coverage Ratio: A minimum interest coverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated EBITDA to the Company’s consolidated cash interest expense) as of the last day of any fiscal quarter of 2.50 to 1.00. The Company was in compliance with the financial covenants contained in the Credit Agreement as of June 30, 2020. In March 2015, the Company issued $250.0 million of 5.375% unsecured senior notes due March 1, 2025 (the “2025 Senior Notes”). In May 2018, the Company issued $300.0 million of 4.600% unsecured senior notes due May 15, 2028 (the “2028 Senior Notes”). The Company used the net proceeds from the sale of the 2028 Senior Notes to repay certain outstanding notes of the Company and to pre-pay $49.2 million of quarterly principal installment payments under the Term Loan. On February 26, 2020, the Company issued $300.0 million of 3.100% unsecured senior notes due March 1, 2030 (the “2030 Senior Notes”) at a discount of $1.2 million. The Company used a portion of the net proceeds from the sale of the 2030 Senior Notes to redeem all of the outstanding 2025 Senior Notes. The Company used the remaining net proceeds to pre-pay all outstanding future quarterly principal installments, as well as pay down a portion of the balloon payment due at maturity on the Term Loan. The Company recognized approximately $8.5 million of expense associated with the Senior Notes transaction, comprised of unamortized debt issuance costs and call premium costs on the 2025 Senior Notes. Expenses related to the transaction are included in interest expense. Additionally, approximately $2.9 million of debt issuance costs were capitalized to long-term debt in connection with the transaction. The 2028 Senior Notes and the 2030 Senior Notes were issued pursuant to an indenture (the “Indenture”) between the Company and a trustee. The Indenture contains customary affirmative and negative covenants. The Company has the option to redeem the 2028 and 2030 Senior Notes at any time for a premium. In September 2019, the Company entered into a 220.0 million Chinese renminbi uncommitted line of credit to provide short-term finance support to operations in China. There was 35.0 million Chinese renminbi ($4.9 million) outstanding on the uncommitted line of credit at June 30, 2020. The line of credit carries a variable interest rate that is set by the lender, which was 3.5% at June 30, 2020. The fair value of the long-term debt is estimated based upon Level 2 inputs to reflect market rate of the Company’s debt. At June 30, 2020 , t he fair value of the 202 8 Senior Notes and the 20 30 Senior Notes was estimated to be $327 million ( $322 million at September 30, 201 9 ) and $301 million , respectively. The fair value of the Term Loan approximated book value at both June 30, 2020 and September 30, 201 9 . See Note 20 of the Notes to Condensed Consolidated Financial Statements for the definition of a Level 2 input.

Product Warranties Disclosures [Abstract]
Warranties	1 4 . Warranties The Company’s products generally carry explicit warranties that extend from six months to five years, based on terms that are generally accepted in the marketplace. Selected components (such as engines, transmissions, tires, etc.) included in the Company’s end products may include manufacturers’ warranties. These manufacturers’ warranties are generally passed on to the end customer of the Company’s products, and the customer would generally deal directly with the component manufacturer. Provisions for estimated warranty and other related costs are recorded at the time of sale and are periodically adjusted to reflect actual experience. Certain warranty and other related claims involve matters of dispute that ultimately are resolved by negotiation, arbitration or litigation. At times, warranty issues arise that are beyond the scope of the Company’s historical experience. It is reasonably possible that additional warranty and other related claims could arise from disputes or other matters in excess of amounts accrued; however, the Company does not expect that any such amounts, while not determinable, would have a material effect on the Company’s consolidated financial condition, results of operations or cash flows. Changes in the Company’s assurance-type warranty liability were as follows (in millions): Nine Months Ended June 30, 2020 2019 Balance at beginning of period $ 65.1 $ 75.3 Adoption of ASC 606 — (14.4 ) Warranty provisions 29.3 37.5 Settlements made (40.1 ) (37.5 ) Changes in liability for pre-existing warranties, net 12.1 1.2 Foreign currency translation 0.1 (0.2 ) Balance at end of period $ 66.5 $ 61.9 Due to the adoption of ASC 606, the Company determined that certain warranties previously classified as assurance-type warranties are service-type warranties. The liabilities associated with service-type warranties are disclosed in Note 3 of the Notes to Condensed Consolidated Financial Statements.

Guarantee Arrangements	1 5 . Guarantee Arrangements Customers of the Company, from time to time, may fund purchases of the Company’s equipment through third-party finance companies. In certain instances, the Company may be requested to provide support for these arrangements through credit or residual value guarantees, by which the Company agrees to make payments to the finance companies in certain circumstances as further described below. Credit Guarantees: The Company is party to multiple agreements whereby at June 30, 2020 the Company guaranteed an aggregate of $750.5 million in indebtedness of customers. The Company estimated that its maximum loss exposure under these contracts at June 30, 2020 was $151.3 million . Terms of these guarantees coincide with the financing arranged by the customer and generally do not exceed five years. Under the terms of these agreements and upon the occurrence of certain events, the Company generally has the ability to, among other things, take possession of the underlying collateral. If the financial condition of the customers were to deteriorate and result in their inability to make payments, then loss provisions in excess of amounts provided for at inception may be required. Given the Company’s position as original equipment manufacturer and its knowledge of end markets, the Company, when called upon to fulfill a guarantee, generally has been able to liquidate the financed equipment at a minimal loss, if any, to the Company. While the Company does not expect to experience losses under these agreements that are materially in excess of the amounts reserved, it cannot provide any assurance that the financial condition of the third parties will not deteriorate resulting in the third parties’ inability to meet their obligations. In the event that this occurs, the Company cannot guarantee that the collateral underlying the agreements will be sufficient to avoid losses materially in excess of the amounts reserved. Any losses under these guarantees would generally be mitigated by the value of any underlying collateral, including financed equipment. During periods of economic weakness, collateral values generally decline and can contribute to higher exposure to losses. Residual Value Guarantees: The Company is party to multiple agreements whereby at June 30, 2020 the Company guaranteed to support an aggregate of $99.6 million of customer equipment value. The Company estimated that its maximum loss exposure under these contracts at June 30, 2020 was $11.7 million. Terms of these guarantees coincide with the financing arranged by the customer and generally do not exceed five years. Under the terms of these agreements, the Company guarantees that a piece of equipment will have a minimum residual value at a future date. If the counterparty is not able to recover the agreed upon residual value through sale, or alternative disposition, the Company is responsible for a portion of the shortfall. The Company is generally able to mitigate a portion of the risk associated with these guarantees by staggering the maturity terms of the guarantees, diversification of the portfolio and leveraging knowledge gained through the Company’s own experience in the used equipment markets. There can be no assurance the Company’s historical experience in used equipment markets will be indicative of future results. The Company’s ability to recover losses experienced from its guarantees may be affected by economic conditions in used equipment markets at the time of loss. During periods of economic weakness, residual values generally decline and can contribute to higher exposure to losses. Changes in the Company’s guarantee liabilities were as follows (in millions): Three Months Ended June 30, Nine Months Ended June 30, 2020 2019 2020 2019 Balance at beginning of period $ 16.2 $ 12.9 $ 15.8 $ 10.4 Provision for new credit guarantees 0.5 2.3 3.7 6.7 Changes for pre-existing guarantees, net (1.8 ) (0.1 ) (0.4 ) — Amortization of previous guarantees 0.2 (1.0 ) (4.0 ) (3.0 ) Foreign currency translation 0.1 — 0.1 — Balance at end of period $ 15.2 $ 14.1 $ 15.2 $ 14.1

Restructuring And Related Activities [Abstract]
Restructuring and Other Charges	1 6 . Restructuring and Other Charges On June 29, 2020, the Company committed to a series of restructuring activities within its Access Equipment segment. On that day, the Company announced that it would close its Medias, Romania manufacturing facility. The Company intends to relocate production to factories in the United States, Mexico and China. The Company also announced that it would close its service center in Riverside, California. Both facilities are being closed to simplify and better align operations to support customers and enable sustainable growth. The Company intends to cease all operations in Medias by June 30, 2021 and in Riverside by September 30, 2020. In addition, the Access Equipment segment initiated targeted reductions in its salaried workforce in response to the ongoing COVID-19 pandemic. The Company expects to incur restructuring charges consisting of severance costs, other post-employment-related benefits, lease impairment and accelerated depreciation of approximately $10.0 million during fiscal 2020. The Company expects another $5.3 million of restructuring costs related to these activities in fiscal 2021. On July 23, 2020, the Company committed to a series of restructuring activities within the Commercial segment. On that day, the Company announced that it will cease production of rear discharge concrete mixers at its Dodge Center, Minnesota facility and relocate it to other concrete mixer factories in North America. The Dodge Center factory will focus on refuse collection vehicle manufacturing. The Company believes both product lines will benefit from focused facilities. The Company intends to cease all concrete mixer operations in Dodge Center by December 31, 2020. In addition, the Commercial segment initiated reductions in its salaried workforce in response to the ongoing COVID-19 pandemic. The Company expects to incur restructuring charges consisting of severance costs, other post-employment-related benefits and accelerated depreciation related to the activities of approximately $9.0 million during fiscal 2020.

Commitments And Contingencies Disclosure [Abstract]
Contingencies, Significant Estimates and Concentrations	1 7 . Contingencies, Significant Estimates and Concentrations Personal Injury Actions and Other - Product and general liability claims are made against the Company from time to time in the ordinary course of business. The Company is generally self-insured for future claims up to $5.0 million per claim. Accordingly, a reserve is maintained for the estimated costs of such claims. At June 30, 2020 and September 30, 2019, the estimated net liabilities for product and general liability claims totaled $34.8 million and $36.2 million, respectively. There is inherent uncertainty as to the eventual resolution of unsettled claims. Management, however, believes that any losses in excess of established reserves will not have a material effect on the Company’s financial condition, results of operations or cash flows. Market Risks - The Company was contingently liable under bid, performance and specialty bonds totaling $712.7 million and $552.2 million at June 30, 2020 and September 30, 2019, respectively. Open standby letters of credit issued by the Company’s banks in favor of third parties totaled $62.1 million and $63.7 million at June 30, 2020 and September 30, 2019, respectively. Other Matters - The Company is subject to environmental matters and legal proceedings and claims, including patent, antitrust, product liability, warranty and state dealership regulation compliance proceedings, that arise in the ordinary course of business. Although the final results of all such matters and claims cannot be predicted with certainty, management believes that the ultimate resolution of all such matters and claims will not have a material effect on the Company’s financial condition, results of operations or cash flows. Actual results could vary, among other things, due to the uncertainties involved in litigation. Major contracts for military systems are performed over extended periods of time and are subject to changes in scope of work and delivery schedules. Pricing negotiations on changes and settlement of claims often extend over prolonged periods of time. The Company’s ultimate profitability on such contracts may depend on the eventual outcome of an equitable settlement of contractual issues with the Company’s customers.

Accounting Policies [Abstract]
New Accounting Standards	New Accounting Standards In February 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases (Topic 842) (Accounting Standards Codification (ASC) 840) The new standard provided a number of optional practical expedients for transition. The Company elected to adopt the standard using the package of practical expedients, which allowed the Company not to reassess prior conclusions about lease identification, lease classification and initial direct costs. In addition, the new guidance provides practical expedients for an entity’s ongoing lessee accounting. The Company has elected not to separate payments for lease components from payments for non-lease components for any classes of assets. The Company has elected the short-term lease recognition exemption for all leases that qualify, which means ROU assets and lease liabilities are not recognized for leases with an initial term of twelve months or less. The most significant quantitative effect of adoption relates to the recognition of ROU assets and lease liabilities on the balance sheet for operating leases. The adoption did not have a material impact on the Company’s results of operations or cash flows. The cumulative effect of initially applying the new leasing guidance to the Company’s Condensed Consolidated Financial Statements as of October 1, 2019 was as follows (in millions): Balance as of September 30, 2019 Cumulative Impact from Adopting New Lease Standard Balance as of October 1, 2019 Assets Other current assets $ 78.9 $ (0.5 ) $ 78.4 Total current assets 3,408.3 (0.5 ) 3,407.8 Other long-term assets 156.4 179.5 335.9 Total assets 5,566.3 179.0 5,745.3 Liabilities and Shareholders’ Equity Other current liabilities $ 307.3 $ 46.4 $ 353.7 Total current liabilities 1,741.9 46.4 1,788.3 Other long-term liabilities 405.6 132.6 538.2 Total liabilities and shareholders’ equity 5,566.3 179.0 5,745.3 See Note 12 of the Notes to Condensed Consolidated Financial Statements for additional information regarding the Company’s accounting for leases. Standards not yet adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740) , Simplifying the Accounting for Income Taxes . The standard simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740 such as recognizing deferred taxes for equity investments, the incremental approach to performing intraperiod tax allocation and calculating income taxes in interim periods . The standard also simplif ies accounting for income taxes under U.S. GAAP by clarifying and amending existing guidance , including the recognition of deferred taxes for goodwill , the a llocati on of taxes to members of a consolidated group and requiring that an entity reflect the effect of enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date . The Company will be required to adopt ASU 2019-12 as of October 1, 2021. Early adoption is permitted. The Company is currently evaluating the impact of 2019-12 on the Company’s consolidated financial statements.
