	Discontinued Operations
	In March 2013, the Company discontinued production of ambulances, which were sold under the Medtec brand name. Medtec was previously included in the Company's fire & emergency segment. Due to the closure of the business, it has been segregated from continuing operations and reported as discontinued operations in the Condensed Consolidated Statements of Income. Results of discontinued operations for the three months ended December 31, 2012 were as follows (in millions):

	Receivables consisted of the following (in millions):
		December 31,			September 30,
		2013			2013
	U.S. government:
	Amounts billed	$	80.9		$	118.3
	Costs and profits not billed	33.1			31.7

	Less allowance for doubtful accounts	(20.5		)	(20.4		)
		$	710.5		$	814.1
	Costs and profits not billed includes undefinitized change orders on existing long-term contracts and “not-to-exceed” undefinitized contracts whereby the Company cannot invoice the customer the full price under the contract or contract change order until such contract or change order is definitized and agreed to with the customer following a review of costs under such a contract or change order, even though the contract deliverables may have been met. Definitization of a change order on an existing long-term contract or a sole source contract begins when the U.S. government customer undertakes a detailed review of the Company’s submitted costs and proposed margin related to the contract and concludes with a final change order. The Company recognizes revenue on undefinitized contracts to the extent that it can reasonably and reliably estimate the expected final contract price and when collectability is reasonably assured. At December 31, 2013, the Company had recorded $5.1 million of revenue on contracts which remained undefinitized as of that date. To the extent that contract definitization results in changes to previously estimated or incurred costs or revenues, the Company records those adjustments as a change in estimate. The Company recorded revenue of $7.5 million and $3.5 million for the three months ended December 31, 2013 and 2012, respectively, related to changes in estimates on these contracts. The changes increased net income by $4.7 million, or $0.05 per diluted share, and $2.2 million, or $0.02 per diluted share, for the three months ended December 31, 2013 and 2012, respectively.

	Finance Receivables: Finance receivables represent sales-type leases resulting from the sale of the Company's products and the purchase of finance receivables from lenders pursuant to customer defaults under program agreements with finance companies. Finance receivables originated by the Company generally include a residual value component. Residual values are determined based on the expectation that the underlying equipment will have a minimum fair market value at the end of the lease term. This residual value accrues to the Company at the end of the lease. The Company uses its experience and knowledge as an original equipment manufacturer and participant in end markets for the related products along with third-party studies to estimate residual values. The Company monitors these values for impairment on a periodic basis and reflects any resulting reductions in value in current earnings. Finance receivables are written down if management determines that the specific borrower does not have the ability to repay the loan amounts due in full.
	Delinquency is the primary indicator of credit quality of finance receivables. The Company maintains a general allowance for finance receivables considered doubtful of future collection based upon historical experience. Additional allowances are established based upon the Company’s perception of the quality of the finance receivables, including the length of time the receivables are past due, past experience of collectability and underlying economic conditions. In circumstances where the Company believes collectability is no longer reasonably assured, a specific allowance is recorded to reduce the net recognized receivable to the amount reasonably expected to be collected. The terms of the finance agreements generally give the Company the ability to take possession of the underlying collateral. The Company may incur losses in excess of recorded allowances if the financial condition of its customers were to deteriorate or the full amount of any anticipated proceeds from the sale of the collateral supporting its customers’ financial obligations is not realized.
	Notes Receivable: Notes receivable include amounts related to refinancing of trade accounts and finance receivables. As of December 31, 2013, approximately 90% of the notes receivable balance outstanding was due from two parties. The Company routinely evaluates the creditworthiness of its customers and establishes reserves where the Company believes collectability is no longer reasonably assured. Notes receivable are written down if management determines that the specific borrower does not have the ability to repay the loan in full. Certain notes receivable are collateralized by a security interest in the underlying assets and/or other assets owned by the debtor. The Company may incur losses in excess of recorded allowances if the financial condition of its customers were to deteriorate or the full amount of any anticipated proceeds from the sale of the collateral supporting its customers' financial obligations is not realized.
	Quality of Finance and Notes Receivable: The Company does not accrue interest income on finance and notes receivables in circumstances where the Company believes collectability is no longer reasonably assured. Any cash payments received on nonaccrual finance and notes receivables are applied first to principal balances. The Company does not resume accrual of interest income until the customer has shown that it is capable of meeting its financial obligations by making timely payments over a sustained period of time. For the three months ended December 31, 2013 and 2012, the Company recognized interest income as the result of the receipt of payment from a customer on a note receivable on nonacrrual status of $0.1 million and $2.3 million, respectively. The Company determines past due or delinquency status based upon the due date of the receivable.
	Receivables subject to specific reserves also include loans that the Company has modified in troubled debt restructurings as a concession to customers experiencing financial difficulty. To minimize the economic loss, the Company may modify certain finance and notes receivable. Modifications generally consist of restructured payment terms and time frames in which no payments are required. At December 31, 2013, restructured finance receivables and notes receivables were $1.2 million and $18.7 million, respectively. Losses on troubled debt restructurings were not significant during the three months ended December 31, 2013 and 2012.

	Recorded investments generally represent the Company’s maximum exposure to loss as a result of the Company’s ownership interest. Earnings or losses are reflected in “Equity in earnings of unconsolidated affiliates” in the Condensed Consolidated Statements of Income.
	The Company and an unaffiliated third party are joint venture partners in RiRent Europe BV ("RiRent"). RiRent maintains a fleet of access equipment for short-term lease to rental companies throughout most of Europe. The re-rental fleet provides rental companies with equipment to support requirements on short notice. RiRent does not provide services directly to end users. The Company made no sales to RiRent during the three month period ended December 31, 2013. Sales to RiRent for the three months ended December 31, 2012 were $0.2 million. The Company recognizes income on sales to RiRent at the time of shipment in proportion to the outside third-party interest in RiRent and recognizes the remaining income ratably over the estimated useful life of the equipment, which is generally five years. Indebtedness of RiRent is secured by the underlying leases and assets of RiRent. All such RiRent indebtedness is non-recourse to the Company and its partner. Under RiRent’s €12.0 million bank credit facility, the partners of RiRent have committed that RiRent will maintain an overall equity to asset ratio of at least 30.0% (RiRent's equity to asset ratio was 72.2% as of December 31, 2013).

	Equipment on operating lease to others represents the cost of equipment shipped to customers for whom the Company has guaranteed the residual value and equipment on short-term leases. These transactions are accounted for as operating leases with the related assets capitalized and depreciated over their estimated economic lives of five to ten years. Cost less accumulated depreciation for equipment on operating lease to others at December 31, 2013 and September 30, 2013 was $22.5 million and $14.0 million, respectively.

	The Company maintains a senior secured credit agreement with various lenders (the “Credit Agreement”). The Credit Agreement provides for (i) a revolving credit facility (“Revolving Credit Facility”) that matures in October 2015 with an initial maximum aggregate amount of availability of $525 million and (ii) a $438.75 million term loan (“Term Loan”) due in quarterly principal installments of $16.25 million with a balloon payment of $341.25 million due at maturity in October 2015. At December 31, 2013, outstanding letters of credit of $81.5 million reduced available capacity under the Revolving Credit Facility to $443.5 million.
	The Company’s obligations under the Credit Agreement are guaranteed by certain of its domestic subsidiaries, and the Company will guarantee the obligations of certain of its subsidiaries under the Credit Agreement to the extent such subsidiaries borrow directly under the Credit Agreement. Subject to certain exceptions, the Credit Agreement is secured by (i) a first-priority perfected lien and security interests in substantially all of the personal property of the Company, each material subsidiary of the Company and each subsidiary guarantor, (ii) mortgages upon certain real property of the Company and certain of its domestic subsidiaries and (iii) a pledge of the equity of each material subsidiary and each subsidiary guarantor.
	Under the Credit Agreement, the Company must pay (i) an unused commitment fee ranging from 0.25% to 0.50% per annum of the average daily unused portion of the aggregate revolving credit commitments under the Credit Agreement and (ii) a fee ranging from 0.75% to 1.25% per annum of the maximum amount available to be drawn for each performance 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 December 31, 2013, the interest spread on the Revolving Credit Facility and Term Loan was 150 basis points. The weighted-average interest rate on borrowings outstanding under the Term Loan at December 31, 2013 was 1.67%.
	The Credit Agreement contains various restrictions and covenants, including requirements that the Company maintain certain financial ratios at prescribed levels and restrictions on the ability of the Company and certain of its subsidiaries to consolidate or merge, create liens, incur additional indebtedness, dispose of assets, consummate acquisitions and make investments in joint ventures and foreign subsidiaries.
	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 4.50 to 1.0.
	•	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 1.0.
	•	Senior Secured Leverage Ratio: A maximum senior secured leverage ratio (defined as, with certain adjustments, the ratio of the Company’s consolidated secured indebtedness to the Company’s consolidated EBITDA) of 2.75 to 1.0.
	The Company was in compliance with the financial covenants contained in the Credit Agreement as of December 31, 2013 and expects to be able to meet the financial covenants contained in the Credit Agreement over the next twelve months.
	Additionally, with certain exceptions, the Credit Agreement limits the ability of the Company to pay dividends and other distributions, including repurchases of shares of Common Stock. However, so long as no event of default exists under the Credit Agreement or would result from such payment, the Company may pay dividends and other distributions after April 1, 2012 in an aggregate amount not exceeding the sum of:
	i.	$485 million; plus
	ii.	50% of the consolidated net income of the Company and its subsidiaries (or if such consolidated net income is a deficit, minus 100% of such deficit), accrued on a cumulative basis during the period beginning on April 1, 2012 and ending on the last day of the fiscal quarter immediately preceding the date of the applicable proposed dividend or distribution; plus
	iii.	100% of the aggregate net proceeds received by the Company subsequent to March 31, 2012 either as a contribution to its common equity capital or from the issuance and sale of its Common Stock.
	In March 2010, the Company issued $250.0 million of 8¼% unsecured senior notes due March 1, 2017 and $250.0 million of 8½% unsecured senior notes due March 1, 2020 (collectively, the “Senior Notes”). The Senior Notes were issued pursuant to an indenture (the “Indenture”) among the Company, the subsidiary guarantors named therein and a trustee. The Indenture contains customary affirmative and negative covenants. The Company has the option to redeem the Senior Notes due 2017 and Senior Notes due 2020 for a premium after March 1, 2014 and March 1, 2015, respectively. Certain of the Company’s subsidiaries fully, unconditionally, jointly and severally guarantee the Company’s obligations under the Senior Notes. See Note 21 of the Notes to Condensed Consolidated Financial Statements for separate financial information of the subsidiary guarantors.
	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 December 31, 2013, the fair value of the Senior Notes was estimated to be $538 million and the fair value of the Term Loan approximated book value. See Note 13 of the Notes to Condensed Financial Statements for the definition of a level 2 input.

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.

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 adverse effect on the Company's consolidated financial condition, results of operations or cash flows.

	Guarantee Arrangements
	The Company is party to multiple agreements whereby it guarantees an aggregate of $392.4 million in indebtedness of customers. The Company estimated that its maximum loss exposure under these agreements at December 31, 2013 was $97.0 million. Under the terms of these and various related 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 additional accruals may be required. 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 customers will not deteriorate resulting in the customers' 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, and are generally subject to the finance company's ability to provide the Company clear title to foreclosed equipment and other conditions. During periods of economic weakness, collateral values generally decline and can contribute to higher exposure to losses.

Derivative Financial Instruments and Hedging Activities

The Company has used forward foreign currency exchange contracts (“derivatives”) to reduce the exchange rate risk of specific foreign currency denominated transactions. These derivatives typically require the exchange of a foreign currency for U.S. dollars at a fixed rate at a future date. At times, the Company has designated these hedges as either cash flow hedges or fair value hedges under Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging. At December 31, 2013 and 2012, the Company had no forward foreign exchange contracts designated as hedges.

The Company has entered into forward foreign currency exchange contracts to create an economic hedge to manage foreign exchange risk exposure associated with non-functional currency denominated payables resulting from global sourcing activities. The Company has not designated these derivative contracts as hedge transactions under FASB ASC Topic 815, and accordingly, the mark-to-market impact of these derivatives is recorded each period in current earnings. The fair value of foreign currency related derivatives is included in the Condensed Consolidated Balance Sheets in “Other current assets” and “Other current liabilities.” At December 31, 2013, the U.S. dollar equivalent of these outstanding forward foreign exchange contracts totaled $99.0 million in notional amounts, including $47.1 million in contracts to sell Euro, $23.9 million in contracts to sell Australian dollars and $9.5 million in contracts to buy U.K. pound sterling, with the remaining contracts covering a variety of foreign currencies.

Fair Value Measurement	'
	Fair Value Measurement
	FASB ASC Topic 820, Fair Value Measurements and Disclosures, defines fair value as the price that would be received to sell an asset or paid to transfer a liability (i.e., exit price) in an orderly transaction between market participants at the measurement date. FASB ASC Topic 820 requires disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the assumptions (i.e., inputs) used in the valuation. Level 1 provides the most reliable measure of fair value, while Level 3 generally requires significant management judgment. The three levels are defined as follows:
	Level 1:	Unadjusted quoted prices in active markets for identical assets or liabilities.
	Level 2:	Observable inputs other than quoted prices in active markets for identical assets or liabilities, such as quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.
	Level 3:	Unobservable inputs reflecting management's own assumptions about the inputs used in pricing the asset or liability.
	There were no transfers of assets between levels during the three months ended December 31, 2013.
	As of December 31, 2013, the fair values of the Company’s financial assets and liabilities were as follows (in millions):

	Stock-Based Compensation
	In February 2009, the Company’s shareholders approved the 2009 Incentive Stock and Awards Plan. In January 2012, the Company's shareholders approved amendments to the 2009 Incentive Stock and Awards Plan (as amended, the “2009 Stock Plan”) to add 6.0 million shares to the number of shares available for issuance under the plan. The 2009 Stock Plan replaced the 2004 Incentive Stock and Awards Plan, as amended (the “2004 Stock Plan”). While no new awards will be granted under the 2004 Stock Plan, awards previously made under the 2004 Stock Plan that remained outstanding as of the initial approval date of the 2009 Stock Plan will remain outstanding and continue to be governed by the provisions of the 2004 Stock Plan.
	Under the 2009 Stock Plan, officers, directors, including non-employee directors, and employees of the Company may be granted stock options, stock appreciation rights, performance shares, performance units, shares of Common Stock, restricted stock, restricted stock units or other stock-based awards. The 2009 Stock Plan provides for the granting of options to purchase shares of Common Stock at not less than the fair market value of such shares on the date of grant. Stock options granted under the 2009 Stock Plan generally become exercisable in equal installments over a three-year period, beginning with the first anniversary of the date of grant of the option, unless a shorter or longer duration is established by the Human Resources Committee of the Board of Directors at the time of the option grant. Stock options terminate not more than seven years from the date of grant. Except for performance shares and performance units, vesting is based solely on continued service as an employee of the Company. At December 31, 2013, the Company had reserved 8,677,996 shares of Common Stock available for issuance under the 2009 Stock Plan 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 2009 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, included in the Condensed Consolidated Statements of Income for the three months ended December 31, 2013 and 2012 was $5.9 million ($3.7 million net of tax) and $6.4 million ($4.1 million net of tax), respectively.

	The Company's effective income tax rate was 31.2% and 31.5% of pre-tax income for the three months ended December 31, 2013 and 2012, respectively. The effective income tax rate for the three months ended December 31, 2013 as compared to the statutory income tax rate was favorably impacted by net discrete tax benefits generally related to adjustments to positions taken in prior periods (230 basis points). The effective income tax rate for the three months ended December 31, 2012 was favorably impacted by net discrete tax benefits related to provision to return adjustments (280 basis points).
	The Company’s liability for gross unrecognized tax benefits, excluding related interest and penalties, was $38.9 million and $36.9 million as of December 31, 2013 and September 30, 2013, respectively. As of December 31, 2013, net unrecognized tax benefits, excluding interest and penalties, of $27.1 million would affect the Company’s net income if recognized, including $26.5 million which would impact net income from continuing operations.
	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 three months ended December 31, 2013 and 2012, the Company recognized charges of $0.8 million and $0.7 million, respectively, related to interest and penalties. At December 31, 2013, the Company had accruals for the payment of interest and penalties of $17.3 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 $14.6 million because the Company’s tax positions are sustained on audit, the Company agrees to their disallowance or the applicable statutes of limitations expire.
	The Company files federal income tax returns as well as multiple state, local and non-U.S. jurisdiction tax returns. The Company is regularly audited by federal, state and foreign tax authorities. At December 31, 2013, the Company was under audit by the U.S. Internal Revenue Service for the taxable years ended September 30, 2011 and 2010.

	Earnings Per Share
	Prior to September 1, 2013, the Company granted awards of nonvested stock that contain a nonforfeitable right to dividends, if declared. In accordance with FASB ASC Topic 260, Earnings Per Share, these awards are considered to be participating securities, and as a result, earnings per share is calculated using the two-class method. The two-class method is an earnings allocation method that determines earnings per share for common shares and participating securities. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. Participating securities and common shares have equal rights to undistributed earnings.
	Effective September 1, 2013, new grants of awards of nonvested stock do not contain a nonforfeitable right to dividends during the vesting period. As a result, an employee will forfeit the right to dividends accrued on unvested awards if such awards do not ultimately vest. As such, these awards are not treated as participating securities in the earnings per share calculation as the employees do not have equivalent dividend rights as common shareholders.

	Contingencies, Significant Estimates and Concentrations
	Environmental - As part of its routine business operations, the Company disposes of and recycles or reclaims certain industrial waste materials, chemicals and solvents at third-party disposal and recycling facilities, which are licensed by appropriate governmental agencies. In some instances, these facilities have been and may be designated by the United States Environmental Protection Agency (“EPA”) or a state environmental agency for remediation. Under the Comprehensive Environmental Response, Compensation, and Liability Act and similar state laws, each potentially responsible party (“PRP”) that contributed hazardous substances may be jointly and severally liable for the costs associated with cleaning up these sites. Typically, PRPs negotiate a resolution with the EPA and/or the state environmental agencies. PRPs also negotiate with each other regarding allocation of the cleanup costs.
	The Company had reserves of $1.6 million and $1.9 million for losses related to environmental matters that were probable and estimable at December 31, 2013 and September 30, 2013, respectively. The amount recorded for identified contingent liabilities is based on estimates. Amounts recorded are reviewed periodically and adjusted to reflect additional technical and legal information that becomes available. Actual costs incurred in future periods may vary from the estimates, given the inherent uncertainties in evaluating certain exposures. Subject to the imprecision in estimating future contingent liability costs, the Company does not expect that any sum it may have to pay in connection with these matters in excess of the amounts recorded will have a material adverse effect on the Company’s financial position, results of operations or cash flows.
	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 ($3.0 million per claim prior to April 1, 2013). Accordingly, a reserve is maintained for the estimated costs of such claims. At December 31, 2013 and September 30, 2013, the estimated net liabilities for product and general liability claims were $40.7 million and $45.6 million, respectively, based on available information. 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 adverse 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 $283.2 million and open standby letters of credit issued by the Company’s banks in favor of third parties totaling $81.5 million at December 31, 2013.
	Other Matters - The Company is subject to other 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 adverse effect on the Company’s financial condition, results of operations or cash flows. Actual results could vary due to, among other things, the uncertainties involved in litigation.
	Certain of the Company's sales in the defense segment are made pursuant to contracts with the U.S. government with pricing based on the costs as determined by the Company to produce products or perform services under the contracts. Cost-based pricing is determined under the Federal Acquisition Regulations ("FAR"). The FAR provide guidance on the types of costs that are allowable in establishing prices for goods and services under U.S. government contracts. Pension and other postretirement benefit costs are allocated to contracts as allowed costs based upon the U.S. Government Cost Accounting Standards ("CAS"). The CAS requirements for pension and other postretirement benefit costs differ from the FASB under generally accepted accounting principles in the United States of America. On December 31, 2012, the Oshkosh salaried defined benefit plan was frozen such that salaried employees would no longer accrue additional benefits under this plan. This resulted in a plan curtailment. Per CAS, when there is a plan curtailment of benefits, the contractor must determine the difference between the actuarial accrued liability and the market value of the assets. The difference represents an adjustment to previously-determined pension costs and the government shares in the difference, whether a credit or charge based on that portion of pension plan costs that related to CAS-covered contracts during the applicable time period. The Company believes that it is entitled to an equitable adjustment of approximately $5 million under CAS related to the pension plan curtailment. This amount is subject to negotiation with the U.S. government. Because of uncertainty pertaining to the amount and form of any ultimate settlement (current payment or adjustment to future contracts), the Company has not recognized any income from this matter.

Segment Reporting [Abstract]	'
Business Segment Information	'
	Business Segment Information
	The Company is organized into four reportable segments based on the internal organization used by management for making operating decisions and measuring performance and based on the similarity of customers served, common management, common use of facilities and economic results attained.
	In accordance with FASB ASC Topic 280, Segment Reporting, for purposes of business segment performance measurement, the Company does not allocate to individual business segments costs or items that are of a non-operating nature or organizational or functional expenses of a corporate nature. The caption “Corporate” includes corporate office expenses, share-based compensation, costs of certain business initiatives and shared services benefiting multiple segments, and results of insignificant operations. Identifiable assets of the business segments exclude general corporate assets, which principally consist of cash and cash equivalents, certain property, plant and equipment, and certain other assets pertaining to corporate activities. Intersegment sales generally include amounts invoiced by a segment for work performed for another segment. Amounts are based on actual work performed and agreed-upon pricing, which is intended to be reflective of the contribution made by the supplying business segment.
	Selected financial information concerning the Company’s reportable segments and product lines is as follows (in millions):

	Guarantee Arrangements
	The Company is party to multiple agreements whereby it guarantees an aggregate of $392.4 million in indebtedness of customers. The Company estimated that its maximum loss exposure under these agreements at December 31, 2013 was $97.0 million. Under the terms of these and various related 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 additional accruals may be required. 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 customers will not deteriorate resulting in the customers' 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, and are generally subject to the finance company's ability to provide the Company clear title to foreclosed equipment and other conditions. During periods of economic weakness, collateral values generally decline and can contribute to higher exposure to losses.
