Accounting Policies [Abstract]

Basis of Presentation and Significant Accounting Policies

Basis of Presentation

The preparation of the consolidated financial statements in accordance with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingencies at the date of the financial statements, as well as the reported amounts of revenue and expense during the reporting period. Estimates have been prepared on the basis of the most current and best available information, but actual results could differ materially from those estimates. The results of operations of acquired companies are included in the Company’s results from the closing date of the acquisition and forward.

Consolidation

The consolidated financial statements include the accounts of the Company and its majority-owned subsidiaries and variable interest entities (“VIEs”) for which the Company is the primary beneficiary. Intercompany accounts and transactions have been eliminated in the consolidated financial statements.

If the Company determines that it has a variable interest in a VIE, the Company then evaluates if it is the primary beneficiary of the VIE. The evaluation assesses whether the Company has the power to direct the activities that significantly affect the VIE’s economic performance, including having operational control over each VIE and operating the VIEs under the XPO brand or policies. When changes occur to the design of an entity, the Company reconsiders whether it is subject to the VIE model. The Company continuously evaluates whether it has a controlling financial interest in a VIE. Investors in these entities only have recourse to the assets owned by the entity and not to the Company’s general credit. The Company does not have implicit support arrangements with any VIE. Other than the special purpose entity which the Company consolidates related to the European Trade Securitization Program discussed in Note 10—Debt, assets and liabilities of VIEs for which the Company is the primary beneficiary are not significant to the Company’s consolidated financial statements.

The Company holds a controlling financial interest in other entities where it currently holds, directly or indirectly, more than 50% of the voting rights or where it exercises control through substantive participating rights or as a general partner. Where the Company is a general partner, it considers substantive removal rights held by other partners in determining if it holds a controlling financial interest. The Company reevaluates whether it has a controlling financial interest in these entities when its voting or substantive participating rights change. Income or loss attributable to noncontrolling interests is deducted from net income/loss to determine net income/loss attributable to XPO. The noncontrolling interest reflected in our consolidated financial statements primarily relates to the 13.75% minority interest of Norbert Dentressangle SA (“ND”).

Significant Accounting Policies

Revenue Recognition

In the Company’s Transportation segment, with the exception of the less-than-truckload (“LTL”) business, revenue is recognized at the point in time when delivery is complete and the shipping terms of the contract have been satisfied. Related costs of delivery and service are accrued and expensed in the same period the associated revenue is recognized. For the Company’s LTL business, revenue is recognized based on relative transit time and expenses are recognized as incurred.

In the Company’s Logistics segment, revenue is recognized based on specific, objective criteria which, as discussed below, are identified within the provisions of each contract. Related costs of delivery and service are accrued and expensed in the same period the associated revenue is recognized. Under certain supply chain contracts, billings in excess of revenue recognized are recorded as unearned revenue. Unearned revenue is recognized over the remaining contract period as services are provided. In addition, the Company has deferred certain recoverable direct and incremental costs related to the setup of logistics operations under long-term contracts. These deferred setup costs are recognized as expense over the contract term.

The Company’s Logistics segment recognizes a significant portion of its revenue based on objective criteria that do not require significant estimates or uncertainties. Revenue on cost-reimbursable contracts is recognized by applying a factor to costs as incurred, such factor being determined by the contract provisions. Revenue on unit-price contracts is recognized at the contractual selling prices or as work is completed. Revenue on time and material contracts is recognized at the contractual rates as the labor hours and direct expenses are incurred. Revenue from fixed-price contracts is recognized as services are provided, unless revenue is earned and obligations fulfilled in a different pattern. Certain contracts provide for labor handling charges to be billed for both incoming and outgoing handling of goods at the time the goods are received in a warehouse. For these contracts, revenue is recognized upon receipt for the amounts representing handling of incoming goods and deferred revenue is recorded for the performance of services related to the handling of outgoing goods, which is recognized once the related goods leave the warehouse. Storage revenue is recognized as it is earned based on the length of time the related product is stored in the warehouse. Generally, the contracts contain provisions for adjustments to future pricing based upon changes in volumes, services and other market conditions, such as inflation. Revenue relating to such incentive or contingency payments is recorded when the contingency is satisfied and the Company concludes the amounts are earned.

For all lines of business (other than the Company’s managed expedited freight business and the Company’s Logistics segment with respect to those transactions where its contract logistics business is serving as the customer’s agent in arranging purchased transportation), the Company reports revenue on a gross basis because XPO is the principal in the transaction. For those lines of business where the Company acts as an agent, revenue is recognized on a net basis.

The Company’s global forwarding operations collects certain taxes and duties on behalf of their customers as part of the services offered and arranged for international shipments. The Company presents these collections on a net basis.

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original maturity of three months or less as of the date of purchase to be cash equivalents. Cash and cash equivalents at December 31, 2017 includes $53.3 million of cash collected on receivables which collateralize borrowings related to the European trade securitization program (see Note 10—Debt).

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the contractual amount. The Company records its allowance for doubtful accounts based upon its assessment of various factors. The Company considers historical collection experience, the age of the accounts receivable balances, credit quality of the Company’s customers, any specific customer collection issues that have been identified, current economic conditions, and other factors that may affect the customers’ ability to pay. The Company writes off accounts receivable balances that have aged significantly once all collection efforts have been exhausted and the receivables are no longer deemed collectible from the customer.

The rollforward of the allowance for doubtful accounts is as follows:



	Years Ended December 31,
(In millions)	2017			2016			2015
Beginning balance	$	26.3		$	16.9		$	9.8
Provision, charged to expense	23.9			15.1			12.9
Write-offs, less recoveries, and other adjustments	(7.8		)	(5.7		)	(5.8		)
Ending balance	$	42.4		$	26.3		$	16.9

Property and Equipment

Property and equipment are generally recorded at cost, or in the case of acquired property and equipment, at fair value at the date of acquisition. Maintenance and repair expenditures are charged to expense as incurred. For internally-developed software, all costs incurred in the planning and evaluation stage of internally-developed computer software are expensed as incurred. Costs incurred during the application development stage are capitalized and included in property and equipment. Capitalized software also includes the fair value of acquired internally-developed technology.

Depreciation is computed on a straight-line basis over the estimated useful lives of the assets as follows:



Classification	Estimated Useful Life
Buildings and leasehold improvements	Term of lease to 40 years
Vehicles, containers, tractors, trailers and tankers	3 to 14 years
Rail cars and chassis	15 to 30 years
Machinery and equipment	3 to 10 years
Office and warehouse equipment	3 to 10 years
Computer software and equipment	1 to 6 years

Asset Retirement Obligations

A liability for an asset retirement obligation (“ARO”) is recorded in the period in which it is incurred. When an ARO liability is initially recorded, the Company capitalizes the cost by increasing the carrying amount of the related long-lived asset. For each subsequent period, the liability is increased for accretion expense and the capitalized cost is depreciated over the useful life of the related asset.

Goodwill

Goodwill consists of the excess of cost over the fair value of net assets acquired in business combinations. The Company performs an annual impairment test for goodwill as of August 31 unless events or circumstances indicate impairment of goodwill may have occurred before that time. The Company adopted Accounting Standards Update (“ASU”) 2017-04, Intangibles - Goodwill and Other (Topic 350): “Simplifying the Accounting for Goodwill Impairment” in connection with its annual impairment test as of August 31, 2017. ASU 2017-04 removes the requirement to perform a hypothetical purchase price allocation to measure goodwill impairment (often referred to as “Step 2”). Goodwill impairment, if any, would be measured at the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill.

Prior to the adoption of ASU 2017-04, the goodwill at the reporting units was subject to a two-step impairment test. The first step compared the book value of a reporting unit, including goodwill, with its fair value. If the book value of a reporting unit exceeds its fair value, the Company completed the second step in order to determine the amount of goodwill impairment loss that should be recorded. The Company determines fair values for each of the reporting units using an income approach. For purposes of the income approach, fair value is determined based on the present value of estimated future cash flows, discounted at an appropriate risk-adjusted rate. The Company uses its internal forecasts to estimate future cash flows and includes an estimate of long-term future growth rates based on its most recent views of the long-term outlook for the business.

Accounting guidance allows entities to perform a qualitative assessment (a “step-zero” test) before performing a quantitative analysis. If an entity determines that it is not more-likely-than-not that the fair value of a reporting unit is less than its carry amount, the entity would not need to perform the quantitative analysis described above. The qualitative assessment includes review of macroeconomic conditions, industry and market considerations, internal cost factors, and overall financial performance, among other areas.

For the 2017 goodwill assessment, the Company performed a step-zero qualitative analysis for six of its reporting units. Based on that qualitative assessment, the Company concluded that it is not more likely than not that the fair value of those reporting units was less than their carrying amounts and therefore, further quantitative analysis was not performed. For one reporting unit, the Company elected to proceed directly to the step one quantitative analysis. For the years ended December 31, 2017 and 2016, the Company did not recognize any goodwill impairment.

Intangible Assets

The Company’s intangible assets subject to amortization consist of customer relationships, trade names, and non-compete agreements. The Company reviews long-lived assets to be held-and-used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the sum of the undiscounted expected future cash flows over the remaining useful life of a long-lived asset group is less than its carrying amount, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset group exceeds the fair value of the asset. The Company estimates fair value using the expected future cash flows discounted at a rate commensurate with the risks associated with the recovery of the asset. For the periods presented, the Company did not recognize any impairment of the identified intangible assets. Intangible assets are amortized on a straight-line basis or on a basis consistent with the pattern in which the economic benefits are realized. The range of estimated useful lives and the weighted-average useful lives of the respective intangible assets by type are as follows:



Classification	Estimated Useful Life	Weighted-Average Amortization Period
Customer relationships	5 to 16 years	14 years
Trade names	3 years	3 years
Non-compete agreements	Term of agreement	7 years

Accrued Expenses

Accrued expenses is comprised of the following:



	As of December 31,
(In millions)	2017		2016
Accrued salaries and wages	$	580.6	$	570.9
Accrued transportation and facility charges	437.7		266.9
Accrued value-added tax and other taxes	176.2		145.5
Other accrued expenses	331.3		398.8
Total Accrued Expenses	$	1,525.8	$	1,382.1

Self-Insurance

The Company uses a combination of self-insurance programs and large-deductible purchased insurance to provide for the costs of medical, casualty, liability, vehicular, cargo and workers’ compensation claims. The Company periodically evaluates the level of insurance coverage and adjusts insurance levels based on risk tolerance and premium expense.

The measurement and classification of self-insured costs requires the consideration of historical cost experience, demographic and severity factors, and judgments about current and expected levels of cost per claim and retention levels. These methods provide estimates of the undiscounted liability associated with claims incurred as of the balance sheet date, including estimates of claims incurred but not reported. Changes in these assumptions and factors can affect actual costs paid to settle the claims and those amounts may be different than estimates.

Advertising Costs

Advertising costs are expensed as incurred.

Accumulated Other Comprehensive Income

The components of accumulated other comprehensive income (“AOCI”), net of tax at December 31, 2017 and 2016, are as follows:



(In millions)	Foreign Currency Translation Adjustments			Derivative Hedges			Defined Benefit Plans Liability			Less: AOCI Attributable to Noncontrolling Interests			AOCI Attributable to the Company
As of December 31, 2015	$	(68.5	)	$	6.9		$	(17.0	)	$	6.3		$	(72.3	)

As of December 31, 2017	$	(43.2	)	$	6.8		$	79.1		$	(27.0	)	$	15.7

Income Taxes

The Company accounts for income taxes in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 740, “Income Taxes.” Income taxes and effective tax rates are calculated on a legal entity and jurisdictional basis relying on several factors, including pre-tax earnings, differences between tax laws and accounting rules, statutory tax rates, tax credits, uncertain tax positions, and valuation allowances. The Company uses judgment and estimates in evaluating its tax positions.

Under ASC 740, deferred income taxes arise from temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements. Valuation allowances are established when, in management’s judgment, it is more likely than not that its deferred tax assets will not be realized. In assessing the need for a valuation allowance, management weighs the available positive and negative evidence, including limitations on the use of tax losses and other carryforwards due to changes in ownership, historic information, and projections of future taxable income that include and exclude future reversals of taxable temporary differences.

The Company’s tax returns are subject to examination by U.S. Federal and state and foreign taxing jurisdictions. ASC 740 clarifies the accounting for uncertainty in income taxes recognized in a Company’s financial statements and prescribes a recognition threshold with measurement attributes for income tax positions taken or expected to be taken on a tax return. Under ASC 740, the impact of an uncertain tax position taken or expected to be taken on an income tax return must be recognized in the financial statements at the largest amount estimated to be sustained under the more likely than not principle. An uncertain income tax position will not be recognized in the financial statements if it does not meet this criteria. The Company adjusts these tax liabilities, including related interest and penalties, based on the current facts and circumstances. Recently enacted tax law changes, published rulings, court cases, and outcomes of tax audits are all considered. While the Company does not expect material changes, it is possible that its actual tax liability will differ from its established tax liabilities for unrecognized tax benefits which may impact its effective tax rate. While it is often difficult to predict the outcome of any particular tax position, the Company believes that its tax provisions reflect the more likely than not outcome of known tax contingencies. The Company reports tax-related interest and penalties as a component of income tax expense.

Foreign Currency Translation and Transactions

The assets and liabilities of foreign subsidiaries that use the local currency as their functional currency are translated to U.S. dollars (“USD”) using the exchange rate prevailing at each balance sheet date, with balance sheet currency translation adjustments recorded in AOCI on the Consolidated Balance Sheets. The assets and liabilities of foreign subsidiaries whose local currency is not their functional currency are remeasured from their local currency to their functional currency and then translated to USD. The results of operations of the Company’s foreign subsidiaries are translated to USD using average exchange rates prevailing for each period presented.

Foreign currency transactions recognized in the Consolidated Statements of Operations are converted to USD by applying the exchange rate prevailing on the date of the transaction. Gains and losses arising from foreign currency transactions and the effects of remeasuring monetary assets and liabilities are recorded in Foreign currency loss (gain) in the Consolidated Statements of Operations.

Foreign currency loss (gain) included in the Consolidated Statements of Operations consisted of the following:



	Years ended December 31,
(In millions)	2017			2016			2015
Unrealized foreign currency option and forward contracts losses (gains)	$	49.4		$	(39.7	)	$	1.0
Realized foreign currency option and forward contracts losses (gains)	15.0			(3.8		)	—
Foreign currency transaction and remeasurement (gains) losses	(6.8		)	3.2			2.4
Remeasurement loss on cash held to purchase ND	—			—			31.7
Loss on forward contract related to ND acquisition	—			—			9.7
Total foreign currency loss (gain)	$	57.6		$	(40.3	)	$	44.8

Fair Value Measurements

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 in an orderly transaction between market participants at the measurement date and classifies the inputs used to measure fair value into the following hierarchy:


•	Level 1—Quoted prices for identical instruments in active markets;


•	Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets; and


•	Level 3—Valuations based on inputs that are unobservable, generally utilizing pricing models or other valuation techniques that reflect management’s judgment and estimates.

The fair value estimates are based upon certain market assumptions and information available to management. The carrying value of the following financial instruments approximated their fair values as of December 31, 2017 and 2016: cash and cash equivalents, accounts receivable, accounts payable, accrued expenses, and current maturities of long-term debt. Fair values approximate carrying values for these financial instruments as they are short-term in nature and are receivable or payable on demand. The Level 1 cash equivalents include money market funds valued using quoted prices in active markets. The Level 2 cash equivalents include short-term investments valued using published interest rates for instruments with similar terms and maturities. For information regarding the fair value hierarchy of the Company’s financial liabilities and derivative instruments, refer to Note 9—Derivative Instruments and Note 10—Debt, respectively.

The following table summarizes the fair value hierarchy of cash equivalents:



	As of December 31, 2017
(In millions)	Carrying Value		Fair Value		Level 1		Level 2
Cash equivalents	$	90.0	$	90.0	$	74.3	$	15.7

	As of December 31, 2016
(In millions)	Carrying Value		Fair Value		Level 1		Level 2
Cash equivalents	$	103.5	$	103.5	$	26.4	$	77.1

Derivative Instruments

The Company records all derivative instruments on the Consolidated Balance Sheets as assets or liabilities at fair value. The Company’s accounting treatment for changes in the fair value of derivative instruments depends on whether the instruments have been designated and qualify as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments, the Company must designate the derivative based upon the exposure being hedged. The gain or loss resulting from fair value adjustments on cash flow hedges are recorded in AOCI on the Consolidated Balance Sheets until the hedged item is recognized in earnings and is presented in the same income statement line item as the earnings effect of the hedged item. The gains and losses on the net investment hedges are recorded as cumulative translation adjustments in AOCI to the extent that the instruments are effective in hedging the designated risk. Gains and losses on cash flow hedges and net investment hedges representing hedge components excluded from the assessment of effectiveness will be amortized into Interest expense in the Consolidated Statements of Operations in a systematic manner. Derivatives that are not designated as hedging instruments are adjusted to fair value through earnings and are recorded in Foreign currency loss (gain) in the Consolidated Statements of Operations, depending on the objective of the derivative.

Defined Benefit Pension Plans

Defined benefit pension plan obligations are calculated using various actuarial assumptions and methodologies. Assumptions include discount rates, inflation rates, expected long-term rate of return on plan assets, mortality rates, and other factors. The assumptions used in recording the projected benefit obligation and fair value of plan assets represent the Company’s best estimates based on information available regarding historical experience and factors that may cause future expectations to differ. Differences in actual experience or changes in assumptions could materially impact the Company’s obligation and future expense amounts.

The impact of plan amendments, actuarial gains and losses and prior-service costs are recorded in AOCI, and are generally amortized as a component of net periodic benefit cost over the remaining service period of the active employees covered by the defined benefit pension plans. Unamortized gains and losses are amortized only to the extent they exceed 10% of the higher of the fair value of plan assets or the projected benefit obligation of the respective plan.

Stock-Based Compensation

The Company accounts for stock-based compensation based on the equity instrument’s grant date fair value. For grants of restricted stock units (“RSUs”) subject to service- or performance-based vesting conditions only, the fair value is established based on the market price on the date of the grant. For grants of RSUs subject to market-based vesting conditions, the fair value is established using the Monte Carlo simulation lattice model. For grants of options and stock appreciation rights (“SARs”), the Company uses the Black-Scholes option pricing model to estimate the fair value of stock-based payment awards. The determination of the fair value of stock-based awards is affected by the Company’s stock price and a number of assumptions, including expected volatility, expected life, risk-free interest rate and expected dividends. The Company accounts for forfeitures as they occur.

The weighted-average fair value of each stock option is amortized over the requisite service period. For options with graded vesting, we recognize compensation cost on a straight-line basis over the requisite service period of the entire award; however, the amount of compensation cost recognized at any date will at least equal the portion of the grant date value of the award that is vested as of that date. For the Company’s performance-based restricted stock units (“PRSUs”), the Company recognizes expense over the awards’ requisite service period based on the number of awards expected to vest with consideration to the actual and expected financial results. If achievement of the performance targets for a PRSU award is not considered to be probable, then no expense is recognized until achievement of such targets becomes probable.

New Accounting Standards

In May 2014, the FASB issued ASU 2014-09, Revenue (Topic 606): “Revenue from Contracts with Customers.” This new standard includes the required steps to achieve the core principle that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will be effective for the Company’s annual and interim periods beginning January 1, 2018, and permits the use of either the retrospective or cumulative effect transition method. The Company will use the modified retrospective transition method. The main areas impacted by ASU 2014-09 include the recognition of revenue using proportionate delivery within the Company’s Transportation segment and gross versus net revenue presentation. On adoption, the Company will record an immaterial increase to total equity as of January 1, 2018 for the cumulative impact of adoption, primarily related to the recognition of in-transit revenue in the transportation business. The Company will provide expanded revenue recognition disclosures based on the new qualitative and quantitative disclosure requirements of the standard upon adoption.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The core principle of this ASU is that a lessee should recognize the assets and liabilities that arise from leases, including operating leases. Under the new requirements, a lessee will recognize in the balance sheet a liability to make lease payments (the lease liability) and the right-of-use asset representing the right to the underlying asset for the lease term. For leases with a term of 12 months or less, the lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. The standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently evaluating the effects this ASU will have on its consolidated financial statements and related disclosures. The Company currently discloses approximately $1,978.5 million in operating leases, refer to Note 16—Commitments and Contingencies, and will evaluate those contracts as well as other existing arrangements to determine if they qualify for lease accounting under the new standard. The Company does not plan to adopt the standard early.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): “Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force).” This ASU addresses eight specific cash flow classification issues with the objective of reducing diversity in practice. Under the new standard, cash payments for debt prepayments or debt extinguishment costs should be classified as outflows for financing activities. Additional cash flow issues covered under the standard include: settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant in relation to the effective interest rate of the borrowing, contingent consideration payments made after a business combination, proceeds from the settlement of insurance claims, proceeds from the settlement of corporate-owned life insurance policies, distributions received from equity method investees, beneficial interests in securitization transactions, and separately identifiable cash flows and application of the predominance principle. This ASU is effective for public entities for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The Company adopted this standard on January 1, 2018. Adoption was on a prospective basis and is not expected to have a material effect on the Company’s consolidated statement of cash flows.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): “Restricted Cash.” This ASU requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and restricted cash. The standard is effective for the Company’s annual and interim periods beginning January 1, 2018 and requires retrospective adoption. The Company does not expect the adoption of this standard to have a material effect on its consolidated financial statements.

In March 2017, the FASB issued ASU 2017-07, Compensation - Retirement Benefits (Topic 715): “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost.” The ASU will change how employers that sponsor defined benefit pension and/or other postretirement benefit plans present the cost of the benefits in the statements of operations. This cost, commonly referred to as the “net periodic benefit cost,” is comprised of several components that reflect different aspects of the arrangement with the employee, including the effect of the related funding. Currently, the Company aggregates the various components of the net periodic benefit cost (including interest cost and the expected return on plan assets) for presentation purposes and includes these costs within Operating income (loss) in the Consolidated Statements of Operations. Under the new guidance, these costs will be presented below Operating income (loss). This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period. The Company will be adopting the standard for the year ending December 31, 2018. The adoption of the standard will have no impact on net income. In connection with the adoption of this new standard, prior periods will be recast to reflect the new presentation. The amount of net periodic benefit cost that will be reclassified below operating income for fiscal years 2017 and 2016 was approximately $42 million and $25 million of income, respectively.

In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718): “Scope of Modification Accounting.” This ASU provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Under the new standard, modification accounting applies unless all the following conditions are met: (i) the fair value of the modified award is the same as the fair value of the original award immediately before the modification, (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification, and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification the original award immediately before the original award is modified. Generally speaking, modification accounting requires an entity to calculate and recognize the incremental fair value of the modified award as compensation cost on the date of modification (for a vested award) or over the remaining service period (for an unvested award). This ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within that reporting period; however, early adoption is permitted. The impact of this guidance, which was applied prospectively on January 1, 2018, is dependent on future modifications, if any, to the Company’s share-based payment awards.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): “Targeted Improvements to Accounting for Hedging Activities.” This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period; however, early adoption is permitted. The purpose of the amendments in this ASU is to better align an entity’s risk management activities and financial reporting for hedging relationships, simplify hedge accounting requirements, and improve the disclosures of hedging arrangements. The Company early-adopted the standard effective October 1, 2017. The adoption of the standard did not have a material impact on the Company’s consolidated financial statements. For additional information, refer to Note 9—Derivative Instruments.

Acquisitions and Divestitures

Con-way Inc.

In October 2015, XPO completed its acquisition of Con-way Inc. (“Con-way”), a transportation and logistics company. The fair value of the total consideration paid by XPO was $2,317.8 million, net of cash acquired of $437.3 million, consisting of $2,706.6 million of cash paid at the time of closing for the purchase of all of Con-way’s outstanding shares of common stock, par value $0.625 (the “Con-way Shares”), $17.6 million representing the portion of replacement equity awards attributable to pre-acquisition service, and a $30.9 million liability for the settlement of certain Con-way stock-based compensation awards.



(In millions)
Cash consideration	$	2,706.6
Liability for equity award settlement	30.9
Portion of replacement equity awards attributable to pre-acquisition service	17.6
Cash acquired	(437.3		)
Total consideration	$	2,317.8

Norbert Dentressangle SA

In April 2015, XPO entered into (1) a Share Purchase Agreement (the “Share Purchase Agreement”) relating to ND, a French société anonyme and (2) a Tender Offer Agreement (the “Tender Offer Agreement” and, together with the Share Purchase Agreement, the “ND Transaction Agreements”) between XPO and ND. The ND Transaction Agreements provided for the acquisition of a majority stake in ND by XPO, followed by an all-cash simplified tender offer by XPO to acquire the remaining outstanding ND shares.

In June 2015, pursuant to the terms of the Share Purchase Agreement, XPO purchased approximately 67% of the share capital of ND and all of the outstanding share subscription warrants granted by ND to employees, directors or other officers of ND and its affiliates (together, the “Share Purchase”). Total cash consideration paid by XPO for the Share Purchase was €1,437.0 million, or $1,603.9 million, excluding acquired debt. This cash consideration reflected only that portion of the fair value of the warrants attributable to service performed by employees, officers, or directors of ND and its affiliates prior to the acquisition date. The remaining balance of the fair value of the warrants was recorded as compensation expense in the post-combination period. The Company also agreed to settle certain ND performance stock awards. Similar to the warrants, the consideration paid by XPO for these stock awards of €11.8 million, or $13.2 million, included only that portion of the fair value attributable to service performed prior to the acquisition date with the balance recorded as compensation expense in the post-combination period. The performance shares were settled in cash with 50% of the awards paid 18 months from the acquisition date and the remaining 50% paid 36 months from the acquisition date. Further, as a result of the acquisition, the Company repaid certain ND indebtedness and related interest rate swap liabilities totaling €628.5 million, or $705.0 million.

In June 2015, XPO launched a mandatory simplified cash offer (the “Tender Offer”) to purchase all of the outstanding ordinary shares of ND (other than the shares already owned by XPO). During the Tender Offer period, the minority shareholders had the right to sell their shares of ND to the Company and the Company had the obligation to purchase those shares at the Tender Offer price. Once the Tender Offer closed on July 17, 2015, the noncontrolling interest is classified as noncontrolling interest in equity in the consolidated balance sheet. The Company purchased 1,921,553 shares under the Tender Offer and acquired a total of approximately 86.25% of the share capital of ND. The total fair value of the consideration paid by XPO in connection with the Tender Offer was €702.5 million, or $784.2 million, which is based on the quoted market price of ND shares on the acquisition date. The total consideration paid by XPO for ND is summarized in the table below in Euros (“EUR”) and USD:



(In millions)	In EUR			In USD
Cash consideration	€	1,437.0		$	1,603.9

Bridge Terminal Transport Services, Inc.

In May 2015, the Company acquired all of the outstanding capital stock of Bridge Terminal Transport Services, Inc. (“BTT”), a leading asset-light drayage provider in the United States. The fair value of the total consideration paid by XPO under the BTT Stock Purchase Agreement was $103.8 million and consisted of $103.1 million of cash paid at the time of closing, including an estimate of the working capital adjustment, and $0.7 million of equity.

UX Specialized Logistics

In February 2015, pursuant to an Asset Purchase Agreement between the Company and Earlybird Delivery Systems, LLC, the Company acquired certain assets of UX Specialized Logistics, LLC (“UX”). The fair value of the total consideration paid under the UX Asset Purchase Agreement was $58.9 million and consisted of $58.1 million of cash paid at the time of closing, including an estimate of the working capital adjustment, and $0.8 million of equity. UX provided last mile logistics and same day delivery services for major retail chains and e-commerce companies.

Pro Forma Financial Information (Unaudited)

The following unaudited pro forma consolidated results of operations for the year ended December 31, 2015 present consolidated information of the Company as if the acquisitions of Con-way and ND had occurred as of January 1, 2015:



	Pro Forma Year Ended December 31,

Diluted loss per share	(2.11		)

The unaudited pro forma consolidated results for the year ended December 31, 2015 was prepared using the acquisition method of accounting and is based on the historical financial information of Con-way, ND, and the Company. The unaudited pro forma consolidated results incorporate historical financial information for all significant acquisitions, without effect to the sale of the North American Truckload operations noted below. The historical financial information has been adjusted to give effect to pro forma adjustments that are: (i) directly attributable to the acquisition, (ii) factually supportable and (iii) expected to have a continuing impact on the combined results. The unaudited pro forma consolidated results are not necessarily indicative of what the Company’s consolidated results of operations actually would have been had it completed these acquisitions on January 1, 2015.

Divestitures

North American Truckload Operations

In October 2016, pursuant to a Stock Purchase Agreement between the Company and a subsidiary of TransForce Inc. (“TransForce”), the Company divested its North American Truckload operations (formerly known as Con-way Truckload) for approximately $558.0 million cash consideration, subject to certain adjustments. The Company also agreed to provide certain specified transition services to TransForce following the transaction. For the period from January 1, 2016 through October 26, 2016, these North American Truckload operations generated revenue of $431.9 million and operating income of $31.9 million. These North American Truckload operations are included in the Company’s Transportation segment through the date of sale. As the proceeds from the sale equaled the carrying value (inclusive of goodwill), there was no gain or loss recognized in connection with this divestiture.

Segment Reporting and Geographic Information

Segment Reporting [Abstract]

Segment Reporting and Geographic Information

The Company is organized into two reportable segments: Transportation Services and Logistics Services.

In the Transportation segment, the Company provides multiple services to facilitate the movement of raw materials, parts and finished goods. The Company accomplishes this by using its proprietary transportation technology, third-party carriers and Company-owned trucks and service centers. XPO’s transportation services include: freight brokerage, last mile, LTL, full truckload, and global forwarding services. Freight brokerage, last mile, and global forwarding are all non-asset or asset-light businesses. LTL and full truckload are asset-based.

In the Logistics segment, referred to as supply chain, the Company provides a range of contract logistics services, including highly engineered and customized solutions, value-added warehousing and distribution, cold chain solutions and other inventory management solutions. Additionally, the Company performs e-commerce fulfillment, order personalization, warehousing, reverse logistics, storage, factory support, aftermarket support, manufacturing, distribution, packaging and labeling, as well as supply chain optimization services such as production flow management.

Certain of the Company’s operating companies provide transportation and related services for other companies outside their reportable segment. Billings for such services are based on negotiated rates, which the Company believes approximate fair value, and are reflected as revenues of the billing segment. These rates are adjusted from time to time based on market conditions. Such intersegment revenues and expenses are eliminated in the Company’s consolidated results and are not separately identified in the following segment information, because the amounts are not material.

Corporate includes corporate headquarters costs for executive officers and certain legal and financial functions, as well as certain other costs and credits not attributed to the Company’s core business. These costs are not allocated to the business segments.

The Company’s Chief Executive Officer, who is the chief operating decision maker (“CODM”), regularly reviews financial information at the reporting segment level in order to make decisions about resources to be allocated to the segments and to assess their performance. Segment results that are reported to the CODM include items directly attributable to a segment as well as those that can be allocated on a reasonable basis. Asset information by segment is not provided to the Company’s CODM as the majority of the Company’s assets are managed at the corporate level.

The Company evaluates performance based on the various financial measures of the respective business segments. The following table presents a reconciliation of reportable segment selected financial data to the consolidated financial statements totals for the years ended December 31, 2017, 2016 and 2015, respectively:



(In millions)	Transportation		Logistics		Corporate			Eliminations			Total

Derivative Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments

In the normal course of business, the Company is exposed to certain risks arising from business operations and economic factors, including fluctuations in interest rates and foreign currencies. To manage the volatility related to this exposure to fluctuations in interest rates and foreign currencies, the Company uses derivative instruments. The objective of these derivative instruments is to reduce fluctuations in the Company’s earnings and cash flows associated with changes in foreign currency exchange rates and interest rates. These financial instruments are not used for trading or other speculative purposes. The Company has not historically incurred, and does not expect to incur in the future, any losses as a result of counterparty default.

The Company formally documents all relationships between hedging instruments and hedged items, as well as the risk management objective and strategy for undertaking various hedge transactions. This process includes linking cash flow hedges to specific forecasted transactions or variability of cash flow to be paid. The Company also formally assesses, both at the hedge’s inception and on an ongoing basis, whether the designated derivative instruments that are used in hedging transactions are highly effective in offsetting changes in cash flow of hedged items. When a derivative instrument is determined not to be highly effective as a hedge or the underlying hedged transaction is no longer probable, hedge accounting is discontinued prospectively.

The following table presents the account on the Consolidated Balance Sheets in which the Company’s derivative instruments have been recognized, the fair value hierarchy level applicable to each type of derivative instrument, and the related notional amounts and fair values:

Cross-Currency Swap Agreements

In May 2017, the Company entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting the fixed-rate USD-denominated Senior Notes due 2023 (see Note 10—Debt), including the semi-annual interest payments, to fixed-rate, EUR-denominated debt. The risk management objective of these transactions is to manage foreign currency risk relating to net investments in subsidiaries denominated in foreign currencies and reduce the variability in the functional currency equivalent cash flows of the Senior Notes due 2023.

During the term of the swap contracts, the Company will receive quarterly interest payments in March, June, September and December of each year from the counterparties based on USD fixed interest rates, and the Company will make quarterly interest payments in March, June, September and December of each year to the counterparties based on EUR fixed interest rates. At maturity, the Company will repay the original principal amount in EUR and receive the principal amount in USD.

In 2015, in connection with the issuance of the Senior Notes due 2022, the Company entered into certain cross-currency swap agreements to manage the related foreign currency exchange risk by effectively converting a portion of the fixed-rate USD-denominated Senior Notes due 2022, including the semi-annual interest payments, to fixed-rate, EUR-denominated debt. The risk management objective is to manage foreign currency risk relating to net investments in subsidiaries denominated in foreign currencies and reduce the variability in the functional currency equivalent cash flows of a portion of the Senior Notes due 2022. During the term of the swap contracts, the Company will receive semi-annual interest payments in June and December of each year from the counterparties based on USD fixed interest rates, and the Company will make semi-annual interest payments in June and December of each year to the counterparties based on EUR fixed interest rates. At maturity, the Company will repay the original principal amount in EUR and receive the principal amount in USD.

The Company has designated the cross-currency swap agreements as qualifying hedging instruments and is accounting for these as net investment hedges. The gains and losses resulting from fair value adjustments to the cross-currency swap agreements are recorded as cumulative translation adjustments in AOCI to the extent that the cross-currency swaps are effective in hedging the designated risk. In the fourth quarter of 2017, and in accordance with the guidance in ASU 2017-12, the Company simplified its method of assessing the effectiveness of its net investment hedging relationships. Under this method, for each reporting period, the change in the fair value of the cross-currency swaps is initially recognized in AOCI. The effective portion of the change in the fair value due to foreign exchange remains in AOCI and the remaining ineffective portion will initially remain in AOCI and then get reclassified from AOCI to interest expense each period in a systematic manner. Cash flows related to the cross-currency swaps that are treated as net investment hedges are included in Operating activities on the Consolidated Statements of Cash Flows.

Additionally, subsequent to the adoption of ASU 2017-12, a portion of the cross currency swap that hedges the Senior Notes due 2023 was de-designated as a net investment hedge and re-designated with a larger notional amount as a cash flow hedge. This cash flow hedge was entered into to manage the related foreign currency exposure from intercompany loans. The amounts in AOCI related to the net investment hedge at the date of de-designation were recognized as cumulative translation adjustments and will remain in AOCI until the subsidiary is sold or substantially liquidated. For the new cash flow hedge, the Company will reclassify a portion of AOCI to earnings to offset the foreign exchange impact in earnings created by the intercompany loans. The Company will also amortize a portion of the AOCI to earnings related to the initial portion of the loss of $3.0 million excluded from the assessment of effectiveness of the cash flow hedge. Cash flows related to cash flow hedges containing an other than insignificant financing element are included in Financing activities on the Consolidated Statements of Cash Flows.

Hedge of Net Investments in Foreign Operations

In addition to the cross-currency swaps, the Company periodically uses foreign currency denominated notes as nonderivative hedging instruments of its net investments in foreign operations. In 2016 and 2015, the Company had designated the Senior Notes due 2021 as a net investment hedge and the gains and losses resulting from the exchange rate adjustments to the designated portion of the foreign currency denominated notes were recorded in AOCI to the extent that the foreign currency denominated notes are effective in hedging the designated risk. As of December 31, 2017, there is no amount of Long-term debt on the Consolidated Balance Sheets that is designated as a net investment hedge of its investments in international subsidiaries that use the EUR as their functional currency. The amount recognized in AOCI during the period that the Senior Notes due 2021 were designated as a net investment hedge remains in AOCI as of December 31, 2017 and will remain in AOCI until the subsidiary is sold or substantially liquidated. From the de-designation date through December 2017, when the 2021 Notes were redeemed, the gains and losses resulting from exchange rate adjustments to the foreign currency denominated notes were recorded in the statement of operations in Foreign currency loss (gain). The Company does not expect amounts that are currently deferred in AOCI to be reclassified to income over the next 12 months.

Interest Rate Hedging

In order to mitigate variability in forecasted interest payments on the Company’s EUR-denominated asset financings that are based on benchmark interest rates (e.g., Euribor), the Company entered into interest rate swaps. The objective was for the cash flows of the interest rate swaps to offset any changes in cash flows of the forecasted interest payments attributable to changes in the benchmark interest rate. The interest rate swaps converted floating rate interest payments into fixed rate interest payments. The Company designated the interest rate swaps as qualifying hedging instruments and accounted for these as cash flow hedges of the forecasted obligations. The gains and losses resulting from fair value adjustments to the designated portion of the interest rate swaps were recorded in AOCI and will be reclassified from AOCI to interest expense on the dates that interest payments accrue, or when the hedged item becomes probable not to occur. The Company hedged its exposure to the variability in future cash flows for forecasted interest payments through the maturity date of the swap in December 2017. During the years ended December 31, 2017 and 2016, certain interest rate swaps were not designated as hedges. The gains and losses related to the interest rate swaps not designated as hedges were included in Interest expense in the Consolidated Statements of Operations. Cash flows related to the interest rate swaps were included in Operating activities on the Consolidated Statements of Cash Flows.

Foreign Currency Option and Forward Contracts

In order to mitigate the currency translation risk which results from converting the financial statements of the Company’s international operations, which primarily use the EUR and British Pound Sterling (“GBP”) as their functional currency, the Company uses foreign currency option and forward contracts. Additionally, the Company may use foreign currency forward contracts to mitigate the foreign currency exposure from intercompany loans. The foreign currency contracts were not designated as qualifying hedging instruments as of December 31, 2017 or 2016. The contracts are not speculative; rather, they are used to manage the Company’s exposure to foreign currency exchange rate fluctuations. The contracts expire in 12 months or less. Gains or losses on the contracts are recorded in Foreign currency loss (gain) in the Consolidated Statements of Operations. Cash flows related to the foreign currency contracts are included in Operating activities on the Consolidated Statements of Cash Flows, except for the cash flows resulting from forwards designated as hedges of intercompany loans which are included in Financing activities.

The fair value of the debt at December 31, 2017 was $4,816.1 million, of which $2,647.4 million was classified as Level 1 and $2,168.7 million was classified as Level 2 in the fair value hierarchy. The fair value of the debt at December 31, 2016 was $5,234.7 million, of which $3,586.2 million was classified as Level 1 and $1,648.5 million was classified as Level 2. The Level 1 debt was valued using quoted prices in active markets. The Level 2 debt was valued using bid evaluation pricing models or quoted prices of securities with similar characteristics. The fair value of the asset financing arrangements approximates carrying value since the debt is primarily issued at a floating rate, may be prepaid any time at par without penalty, and the remaining life is short-term in nature.

ABL Facility

In October 2015, the Company entered into the Second Amended and Restated Revolving Loan Credit Agreement (the “ABL Facility”) among XPO and certain of XPO’s U.S. and Canadian wholly owned subsidiaries (which include the U.S. subsidiaries of the former Con-way), as borrowers, the other credit parties from time to time party thereto, the lenders party thereto and Morgan Stanley Senior Funding, Inc. (“MSSF”), as agent for such lenders. The ABL Facility replaced XPO’s then existing Amended Credit Agreement, and, among other things, (i) increased the commitments under the ABL Facility to $1.0 billion, (ii) permitted the acquisition of Con-way, and the transactions relating thereto, (iii) reduced the margin on loans under the ABL Facility by 0.25% from that contained in the then existing Amended Credit Agreement and (iv) matures on October 30, 2020. Up to $350 million of the ABL Facility is available for issuance of letters of credit, and up to $50 million of the ABL Facility is available for swing line loans. Total unamortized debt issuance costs related to the ABL Facility classified in other long-term assets at December 31, 2017 and 2016 were $6.2 million and $8.1 million, respectively.

Availability on the ABL Facility is equal to the borrowing base less advances and outstanding letters of credit. The borrowing base includes a fixed percentage of (i) eligible U.S. and Canadian accounts receivable plus (ii) any eligible U.S. and Canadian rolling stock and equipment. At December 31, 2017, the Company had a borrowing base of $1.0 billion and availability under the ABL Facility of $655.4 million at December 31, 2017 after considering outstanding letters of credit on the ABL Facility of $244.6 million. XPO may from time to time increase base availability under the ABL Facility up to $1.0 billion less any then outstanding letters of credit by including into the borrowing additional rolling stock and equipment. A maximum of 20% of the borrowing base can be attributable to the equipment and rolling stock in the aggregate. As of December 31, 2017, the Company was in compliance with the ABL Facility’s financial covenants.

The ABL Facility is secured on a first lien basis by the assets of the credit parties which constitute ABL Facility priority collateral and on a second lien basis by certain other assets. ABL Facility priority collateral consists primarily of U.S. and Canadian accounts receivable as well as any U.S. and Canadian rolling stock and equipment included by XPO in the borrowing base. The Company’s borrowings under the ABL Facility will bear interest at a rate equal to the London Interbank Offered Rate (“LIBOR”) or a Base Rate, as defined in the agreement, plus an applicable margin of 1.50% to 2.00%, in the case of LIBOR loans, and 0.50% to 1.00%, in the case of Base Rate loans. The interest rate on outstanding borrowings at December 31, 2017 was 2.97%. The ABL Facility contains representations and warranties, affirmative and negative covenants and events of default customary for agreements of this nature.

Among other things, the covenants in the ABL Facility limit the Company’s ability to, with certain exceptions: incur indebtedness; grant liens; engage in certain mergers, consolidations, acquisitions and dispositions; make certain investments and restricted payments; and enter into certain transactions with affiliates. In certain circumstances, such as if availability is below certain thresholds, the ABL Facility also requires the Company to maintain a Fixed Charge Coverage Ratio (as defined in the ABL Facility) of not less than 1.00. As of December 31, 2017, the Company is in compliance with this financial covenant. If an event of default under the ABL Facility shall occur and be continuing, the commitments thereunder may be terminated and the principal amount outstanding thereunder, together with all accrued unpaid interest and other amounts owed thereunder, may be declared immediately due and payable. Certain subsidiaries acquired by the Company in the future may be excluded from the restrictions contained in certain of the foregoing covenants.

Term Loan Facility

In October 2015, XPO entered into a Senior Secured Term Loan Credit Agreement (the “Term Loan Credit Agreement”) that provided for a single borrowing of $1.6 billion. The Term Loan Credit Agreement was issued at an original issue discount of $32.0 million.

In March 2017, the Company entered into a Refinancing Amendment (Amendment No. 2 to Credit Agreement) (the “Second Amendment”), by and among XPO, its subsidiaries signatory thereto, as guarantors, the lenders party thereto and MSSF, in its capacity as administrative agent (the “Administrative Agent”), amending that certain Senior Secured Term Loan Credit Agreement, dated as of October 30, 2015 (as amended, amended and restated, supplemented or otherwise modified, including by that certain Incremental and Refinancing Amendment (Amendment No. 1 to Credit Agreement) (the “First Amendment”), dated as of August 25, 2016, the “Term Loan Credit Agreement”).

Pursuant to the Second Amendment, the outstanding $1,481.9 million principal amount of term loans under the Term Loan Credit Agreement (the “Existing Term Loans”) were replaced with $1,494.0 million in aggregate principal amount of new term loans (the “Current Term Loans”) having substantially similar terms as the Existing Term Loans, other than with respect to the applicable interest rate and prepayment premiums in respect of certain voluntary prepayments. Proceeds from the Current Term Loans were used primarily to refinance the Existing Term Loans and to pay interest, fees and expenses in connection therewith.

The interest rate margin applicable to the Current Term Loans was reduced from 2.25% to 1.25%, in the case of base rate loans, and from 3.25% to 2.25%, in the case of LIBOR loans and the LIBOR floor was reduced from 1.0% to 0%. The interest rate on the Current Term Loans was 3.60% at December 31, 2017. The Current Term Loans maturity date remains October 30, 2021. The refinancing resulted in a debt extinguishment charge of $8.3 million during the twelve months ended December 31, 2017.

In August 2016, the Company entered into the First Amendment, pursuant to which the outstanding $1,592.0 million principal amount of term loans under the Term Loan Credit Agreement (the “Old Term Loans”) were replaced with a like aggregate principal amount of new term loans (the “New Term Loans”) having substantially similar terms as the Old Term Loans, other than with respect to the applicable interest rate and prepayment premiums in respect of certain voluntary prepayments. Of the $1,592.0 million of term loans which were refinanced, $1,197.2 million were exchanged and represent a non-cash financing activity. The interest rate margin applicable to the New Term Loans was reduced from 3.50% to 2.25%, in the case of base rate loans, and from 4.50% to 3.25%, in the case of LIBOR loans. The interest rate at December 31, 2016 was 4.25%. Debt extinguishment costs related to various lenders exiting the syndicate were $18.0 million.

In addition, pursuant to the First Amendment, the Company borrowed an additional $400.0 million of Incremental Term B-1 Loans (the “Incremental Term B-1 Loans”) and an additional $50.0 million of Incremental Term B-2 Loans (the “Incremental Term B-2 Loans”). The New Term Loans, Incremental Term B-1 Loans and Incremental Term B-2 Loans have identical terms, other than with respect to original issue discount, and will mature on October 30, 2021.

On November 3, 2016, the Company used the proceeds from sale of the North American Truckload operations to repurchase $555.0 million of Term Loan debt at par. The repurchase of debt resulted in a non-cash debt extinguishment charge of $16.5 million in the fourth quarter of 2016.

Commencing with the fiscal year ending December 31, 2016, the Company must prepay an aggregate principal amount of the Term Loan Facility equal to (a) 50% of Excess Cash Flow, as defined in the agreement, if any, for the most recent fiscal year ended minus (b) the sum of (i) all voluntary prepayments of loans during such fiscal year and (ii) all voluntary prepayments of loans under the ABL Facility or any other revolving credit facilities during such fiscal year to the extent accompanied by a corresponding permanent reduction in the commitments under the credit agreement or any other revolving credit facilities in the case of each of the immediately preceding clauses (i) and (ii), to the extent such prepayments are funded with internally generated cash flow, as defined in the agreement; provided, further, that (x) the Excess Cash Flow percentage shall be 25% if the Consolidated Secured Net Leverage Ratio of Borrower, as defined in the agreement, for the fiscal year was less than or equal to 3.00:1.00 and greater than 2.50:1.00 and (y) the Excess Cash Flow percentage shall be 0% if the Consolidated Secured Net Leverage Ratio of Borrower for the fiscal year was less than or equal to 2.50:1.00. The remaining principal is due at maturity. As of December 31, 2017, the Company’s Consolidated Secured Net Leverage Ratio was less than 2.50:1.00; therefore, no excess cash payment was required.

Senior Notes

In December 2017, the Company redeemed all of its outstanding senior notes due June 2021 (the “2021 Notes”) that were originally issued in 2015. The redemption price for the 2021 Notes was 102.875% of the principal amount of the 2021 Notes, plus accrued and unpaid interest to, but excluding, the date of redemption. The redemption was funded using cash on hand at the date of the redemption. The loss on debt extinguishment was $22.4 million.

In August 2017, the Company redeemed all of its outstanding 7.25% senior notes due January 2018 (the “2018 Notes”). The 2018 Notes has been assumed in connection with the Company’s acquisition on Con-way. The redemption price for the 2018 Notes was 102.168% of the principal amount of the Notes, plus accrued and unpaid interest to, but excluding, the date of redemption. The redemption was funded using cash on hand at the date of the redemption. The loss on debt extinguishment was approximately $5.3 million.

In September 2016, XPO redeemed all of its outstanding 7.875% Senior Notes due 2019. The redemption price for the Senior Notes due 2019 was 103.938% of the principal amount of the Senior Notes due 2019, plus accrued and unpaid interest to, but excluding, the date of redemption. Debt extinguishment costs were $35.2 million.

In August 2016, the Company completed a private placement of $535.0 million aggregate principal amount of 6.125% senior notes due September 1, 2023 (“Senior Notes due 2023”). In June 2015, the Company completed a private placement of $1,600.0 million aggregate principal amount of 6.50% Senior Notes due 2022.

The Senior Notes bear interest payable semiannually, in cash in arrears. The Senior Notes due 2023 mature on September 1, 2023. The Senior Notes due 2022 mature on June 15, 2022.

The Senior Notes are guaranteed by each of the Company’s direct and indirect wholly-owned restricted subsidiaries (other than certain excluded subsidiaries) that are obligors under, or guarantee obligations under, the Company’s ABL Facility (or certain replacements thereof) or guarantee certain capital markets indebtedness of the Company or any guarantor of the Senior Notes. The Senior Notes and the guarantees thereof are unsecured, unsubordinated indebtedness of the Company and the guarantors. Among other things, the covenants of the Senior Notes limit the Company’s ability to, with certain exceptions: incur indebtedness or issue disqualified stock; grant liens; pay dividends or make distributions in respect of capital stock; make certain investments or other restricted payments; prepay or repurchase subordinated debt; sell or transfer assets; engage in certain mergers, consolidations, acquisitions and dispositions; and enter into certain transactions with affiliates.

Senior Debentures

In conjunction with the Company’s acquisition of Con-way, the Company assumed Con-way’s 6.70% Senior Debentures due 2034 (the “Senior Debentures”) with an aggregate principal amount of $300.0 million. The Senior Debentures bear interest payable semiannually, in cash in arrears, and mature on May 1, 2034. In accordance with ASC 805 “Business Combinations,” the Senior Debentures were recorded at fair value on the Con-way acquisition date, resulting in a fair value discount of $101.3 million on October 30, 2015. Including amortization of the fair value adjustment, interest expense on the Senior Debentures is recognized at an annual effective interest rate of 10.96%.

Convertible Senior Notes

The Convertible Senior Notes bore interest payable semi-annually, in cash in arrears, and matured on October 1, 2017.

During the year ended December 31, 2017, the Company issued an aggregate of approximately 3.0 million shares of the Company’s common stock to certain holders of the Convertible Senior Notes in connection with the conversion of the Convertible Senior Notes. The Convertible Senior Notes and shares of common stock underlying the Convertible Senior Notes were registered pursuant to a registration statement on Form S-3. The conversions were allocated to long-term debt and equity in the amounts of $49.0 million and $49.5 million, respectively. A loss on conversion of $0.5 million was recorded as part of these transactions. Certain of these transactions represented induced conversions pursuant to which the Company paid the holder a market-based premium in cash. The negotiated market-based premiums, in addition to the difference between the current fair value and the book value of the Convertible Senior Notes, were reflected in interest expense.

Euro Private Placement Notes

The Euro Private Placement Notes due 2020 have €12.0 million EUR-denominated aggregate principal amount outstanding as of December 31, 2017. The Euro Private Placement Notes due 2020 bear interest payable annually, in cash in arrears, and mature on December 20, 2020.

The Euro Private Placement Notes are subject to leverage ratio and indebtedness ratio financial covenants, as defined in the agreements. ND is required to maintain a leverage ratio of less than or equal to 4.50 and an indebtedness ratio of less than or equal to 2.00 as of each semi-annual testing date. As of December 31, 2017, the latest semi-annual testing date, ND is in compliance with the financial covenants.

Asset Financing

The asset financing arrangements are unsecured and are used to purchase trucks in Europe. The financing arrangements are denominated in USD, EUR, GBP and Romanian New Lei, with primarily floating interest rates. As of December 31, 2017, interest rates on asset financing range from 0.67% to 4.97%, with a weighted average interest rate of 1.23%, and initial terms range from three years to ten years.

European Trade Securitization Program

In October 2017, XPO Logistics Europe SA (“XPO Logistics Europe”), in which the Company holds an 86.25% controlling interest, entered into a European trade receivables securitization program for an aggregate maximum amount of €270 million (approximately $324 million as of December 31, 2017) for a term of three years co-arranged by Crédit Agricole and HSBC. Under the terms of the program, XPO Logistics Europe, or one of its wholly-owned subsidiaries in the United Kingdom or France, sells trade receivables to XPO Collections Designated Activity Company Limited (“XCDAL”), a wholly-owned bankruptcy remote special purpose entity of XPO Logistics Europe. The receivables are funded by senior variable funding notes denominated in the same currency as the corresponding receivables. XCDAL is considered a variable interest entity and is consolidated by XPO Logistics Europe based on its control of the entity’s activities. The receivable balances under this program is reported as accounts receivable on the Company’s consolidated balance sheet and the obligation to return the cash it receives is included in the Company’s long-term debt. At December 31, 2017, the remaining borrowing capacity was €17.7 million (approximately $21.2 million) and the weighted-average interest rate was 1.06%. In the first quarter of 2018, the aggregate maximum amount under the program was increased to €350 million (approximately $420 million).

The receivables securitization program provides additional liquidity to fund XPO Logistics Europe’s operations. Borrowings under the program will bear interest at lenders’ cost of funds plus a margin of 1.05%. The receivables securitization program contains representations and warranties, affirmative and negative covenants, termination events, events of default, indemnities and other obligations on the part of XPO Logistics Europe, certain of its subsidiaries, and XCDAL which are customary for transactions of this nature.

Employee Benefit Plans

Defined Benefit Pension Plans

The Company maintains defined benefit pension plans for certain employees in the United States. These pension plans include qualified plans (the “U.S. Qualified Plans”) that are eligible for certain beneficial treatment under the Internal Revenue Code (“IRC”), as well as non-qualified plans that do not meet the IRC criteria. The Company’s non-qualified defined benefit pension plans (collectively, the “U.S. Non-Qualified Pension Plans” and together with the U.S. Qualified Plans, the “U.S. Plans”) consist mostly of a primary non-qualified supplemental defined benefit pension plan and provide additional benefits for certain employees who are affected by IRC limitations on compensation eligible for benefits available under the qualified plans.

The Company maintained two separate defined benefit pension plans for certain employees in the United Kingdom. On November 1, 2016, the U.K. Plans were merged into one plan (the “U.K. Plan”) in order to reduce overhead and administrative costs, resulting in a $41.7 million prior service credit recognized in AOCI. The amount currently recognized in AOCI is expected to be recognized as a component of net periodic benefit expense (income) over a period of approximately 26 years. In conjunction with the plan merger, a one-time settlement offer was made to certain U.K. Plan participants. On November 30, 2016, the settlement was completed, resulting in a payment of plan benefits of approximately $22.3 million and a reduction of the pension benefit obligation.

The Company also maintains defined benefit pension plans for certain of its foreign subsidiaries. These international defined benefit pension plans are excluded from the disclosures below due to their immateriality. Both the U.S. Plans and U.K. Plan do not allow for new plan participants or additional benefit accruals.

During 2017, the Company offered eligible former employees, who had not yet commenced receiving their pension benefit, an opportunity to receive a lump sum payout of their vested pension benefit. On December 1, 2017, in connection with this offer, one of the Company’s pension plans paid $142.3 million from pension plan assets to those who accepted this offer, thereby reducing its pension benefit obligations. The transaction had no cash impact on the Company but did result in a non-cash pre-tax pension settlement gain of $0.8 million. As a result of the lump sum payout, the Company re-measured the funded status of its pension plan as of the settlement date. To calculate this pension settlement charge, the Company utilized a discount rate of 4.35% through the measurement date and 3.83% thereafter.

Defined benefit pension plan obligations are measured based on the present value of projected future benefit payments for all participants for services rendered to date. The projected benefit obligation is a measure of benefits attributed to service to date assuming that the plan continues in effect and that estimated future events (including turnover and mortality) occur. The net periodic benefit costs are determined using assumptions regarding the projected benefit obligation and the fair value of plan assets as of the beginning of the year. Net periodic benefit costs are recorded in SG&A. The funded status of the defined benefit pension plans, which represents the difference between the projected benefit obligation and the fair value of plan assets, is calculated on a plan-by-plan basis.

Approximately $1.6 million of the amount currently recognized in Other comprehensive income (loss) is expected to be recognized as a component of net periodic benefit expense (income) for the year ended December 31, 2018.

The following table outlines the weighted-average assumptions used to determine the net periodic benefit costs and benefit obligations at December 31:



	U.S. Qualified Plans					U.S. Non-Qualified Plans						U.K. Plan
	2017	2016		2015		2017		2016		2015		2017		2016		2015
Discount rate - net periodic benefit costs	3.83% - 4.35%	4.65	%	4.55	%	4.35	%	4.65	%	4.55	%	2.70	%	3.75	%	3.60	%
Discount rate - benefit obligations	3.55% - 3.71%	4.35	%	4.65	%	3.21% - 3.60%		4.35	%	4.65	%	2.53	%	2.70	%	3.75	%
Expected long-term rate of return on plan assets	2.35% - 5.65%	5.58	%	5.57	%	N/A		N/A		N/A		5.00	%	5.40	%	5.00	%

No rate of compensation increase was assumed as the plans are frozen to additional participant benefit accruals. As of December 31, 2017, the impact of a 25 basis point decrease in the discount rate would increase the projected benefit obligation by approximately $59.0 million, $1.9 million and $55.8 million for the U.S. Qualified Plans, U.S. Non-Qualified Plans and U.K. Plan, respectively.

In 2018, the Company will change how it estimates the interest cost component of net periodic cost for its U.S. and U.K. pension benefit plans. Previously, the Company estimated the interest cost component utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation. The new estimate utilizes a full yield curve approach in the estimation of this component by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to each of the underlying projected cash flows based on time until payment. The new estimate provides a more precise measurement of interest costs by improving the correlation between projected benefit cash flows and their corresponding spot rates. The change does not affect the measurement of the Company’s U.S. and U.K. pension benefit obligation and it is accounted for as a change in accounting estimate, which will be applied prospectively.

Expected benefit payments for the defined benefit pension plans are summarized below. These estimates are based on assumptions about future events. Actual benefit payments may vary from these estimates.



(In millions)	U.S. Qualified Plans		U.S. Non-Qualified Plans		U.K. Plan

Plan Assets

U.S. Qualified Plans

The U.S. Qualified Plans’ assets are segregated from those of the Company and are managed pursuant to a long-term liability driven asset allocation strategy that seeks to mitigate the funded status volatility by increasing exposure to fixed income investments over time. This strategy was developed by analyzing a variety of diversified asset-class combinations in conjunction with the projected liabilities.

The current investment strategy is to achieve a mix of approximately 80% in fixed income securities and 20% of investments in equity securities. The target allocations for fixed income securities includes 100% in domestic fixed income to match domestic projected liabilities. The target allocations for equity securities include 12% in U.S. companies and 8% in international companies. Investments in equity and fixed income securities consist of individual securities held in managed separate accounts as well as commingled investment funds. The investment strategy does not include a meaningful long-term investment allocation to cash and cash equivalents; however, the cash allocation may rise periodically in response to timing considerations regarding contributions, investments, and the payment of benefits and eligible plan expenses. The Company evaluates its defined benefit plans’ asset portfolios for the existence of significant concentrations of risk. Types of investment concentration risks that are evaluated include, but are not limited to, concentrations in a single entity, industry, foreign country and individual fund manager. As of December 31, 2017, there were no significant concentrations of risk in the Company’s defined benefit plan assets.

The investment policy does not allow investment managers to use market-timing strategies or financial derivative instruments for speculative purposes. However, financial derivative instruments are used to manage risk and achieve stated investment objectives regarding duration, yield curve, credit and equity exposures. Generally, the investment managers are prohibited from short selling, trading on margin, and trading commodities, warrants or other options, except when acquired as a result of the purchase of another security, or in the case of options, when sold as part of a covered position.

The assumption of between 2.35% and 5.65% for the overall expected long-term rate of return in 2017 was developed using asset allocation and return expectations. The return expectations are created using long-term historical returns and current market expectations for inflation, interest rates and economic growth.

U.K. Plan

The U.K. Plan’s assets are segregated from those of the Company and invested by trustees, which include Company representatives, with the goal of meeting the U.K. Plan’s projected future pension liabilities. The trustees’ investment objectives are to meet the performance target set in the deficit recovery plan of the U.K. Plan in a risk-controlled framework. The actual asset allocations of the U.K. Plan are in line with the target asset allocations. The implied target asset allocation of the U.K. Plan consists of 28% matching assets (U.K. gilts and cash) and 72% growth assets (consisting of government and credit - commingled funds, illiquid credit, hedge funds, dynamic asset allocation, and risk parity). The target asset allocations of the U.K. Plan includes acceptable ranges for each asset class, which are typically +/- 10% from the target.

The risk parity and dynamic asset allocation categories include investments in multi-asset funds. These funds are designed to provide a diversified exposure to markets with less volatility than equities. Collateral assets consist of U.K. gilts and cash, which are used to back derivative positions that hedge the sensitivity of the liability to changes in interest rates and inflation. Approximately 90% of the actuarial liability sensitivities were hedged as of December 31, 2017. The derivative positions are also used to gain a synthetic exposure to equity markets. The expected return over 2017 was 5.00%. The approach to determine the expected long-term rate of return on plan assets is consistent with the one used for the U.S. Plans.

The following table sets forth the fair values of investments held in the pension plans by major asset category as of December 31, 2017 and 2016, as well as the percentage that each asset category comprises of total plan assets:

For the periods ended December 31, 2017 and 2016, the Company had no investments held in the pension plans within Level 3 of the fair value hierarchy. There was no XPO common stock held in plan assets as of December 31, 2017 or 2016. The U.S. Non-Qualified Pension Plans are unfunded.

Funding

The Company’s funding practice is to evaluate its tax and cash position, as well as the funded status of its plans, in determining its planned contributions. The Company estimates that it will contribute $5.4 million to its U.S. Non-Qualified Plans and $13.2 million to its U.K. Plan in 2018; however, this could change based on variations in interest rates, asset returns and other factors.

Defined Contribution Retirement Plans

The Company’s cost for defined contribution retirement plans was $61.7 million in 2017, $59.1 million in 2016 and $13.0 million in 2015.

Postretirement Medical Plan

The Company sponsors a postretirement medical plan that provides health benefits to certain non-contractual employees at least 55 years of age with at least 10 years of service (the “Postretirement Plan”). The Postretirement Plan does not provide employer-subsidized retiree medical benefits for employees hired on or after January 1, 1993.

Funded Status of Postretirement Medical Plan

The following sets forth the changes in the benefit obligation and the determination of the amounts recognized on the Consolidated Balance Sheets for the Postretirement Plan:



	As of December 31,
(In millions)	2017			2016
Projected benefit obligation at beginning of year	$	50.6		$	54.0
Service cost – benefits earned during the year	0.5			0.5

Net Periodic Benefit Expense for Postretirement Medical Plan

Net periodic benefit expense includes the following:



	Years Ended December 31,
(In millions, except discount rate)	2017			2016			2015
Net periodic benefit expense:
Service cost - benefits earned during the year	$	0.5		$	0.5		$	0.1
Interest cost on projected benefit obligation	1.9			2.2			0.3
Net periodic benefit expense	$	2.4		$	2.7		$	0.4
Discount rate assumption used to calculate interest cost	3.90		%	4.20		%	4.10		%

Expected benefit payments, which reflect expected future service, as appropriate, are summarized below. These estimates are based on assumptions about future events. Actual benefit payments may vary from these estimates.



(In millions)	Benefit Payments
Year ending December 31:
2018	$	3.2
2019	3.0
2020	3.1
2021	3.2
2022	3.2
2023-2027	15.4

The assumed health care cost trend rates used to determine the benefit obligation are as follows:



	2017		2016
Health care cost trend rate assumed for next year	6.24	%	6.49	%
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate)	4.50	%	4.50	%
Year that the rate reaches the ultimate trend rate	2038		2038

Assumed health care cost trends affect the amounts recognized for the Company’s postretirement benefits. A one-percentage-point change in the assumed health care cost trend rate would not have a material effect on the service and interest cost components of net periodic benefit costs or on the accumulated postretirement benefit obligation.

Stockholder's Equity	12 Months Ended
Stockholder's Equity	Dec. 31, 2017
Equity [Abstract]
Stockholder's Equity	Stockholders’ Equity Pursuant to the Company’s Certificate of Incorporation, the Board of Directors may establish one or more series of preferred stock. Other than the Series A Convertible Perpetual Preferred Stock, par value $0.001 per share (the “Series A Preferred Stock”), no shares of preferred stock are currently outstanding Series A Convertible Perpetual Preferred Stock and Warrants In 2011, the Company issued to certain investors, for $75.0 million in cash: (i) an aggregate of 75,000 shares of the Series A Preferred Stock with an initial liquidation preference of $1,000 per share, which are convertible into shares of Company common stock at a conversion price of $7.00 per common share (subject to customary anti-dilution adjustments), and (ii) warrants exercisable for shares of Company common stock at an initial exercise price of $7.00 per common share (subject to customary anti-dilution adjustments) (the “Warrants”). As of December 31, 2017, the outstanding Series A Preferred Stock is convertible into 10.2 million shares of Company common stock and there are outstanding Warrants exercisable for an aggregate of 10.2 million shares of Company common stock. The Series A Preferred Stock ranks, with respect to dividend rights and rights upon liquidation, winding-up or dissolution of the Company, senior to the Company’s common stock and to each other class or series of stock of the Company (including any series of preferred stock) the terms of which do not expressly provide that such class or series ranks senior to or pari passu with the Series A Preferred Stock. The Series A Preferred Stock pays quarterly cash dividends equal to the greater of (i) the “as-converted” dividends on the underlying Company common stock for the relevant quarter and (ii) 4% of the then-applicable liquidation preference per annum. The Series A Preferred Stock is not redeemable or subject to any required offer to purchase, and votes together with the Company’s common stock on an “as-converted” basis on all matters, except as otherwise required by law, and separately as a class with respect to certain matters implicating the rights of holders of shares of Series A Preferred Stock. In July 2017, the Company completed a registered underwritten offering of 11 million shares of its common stock at a public offering price of $60.50 per share (the “Offering”). Of the 11 million shares of common stock, 5 million shares were offered directly by the Company and 6 million shares were offered in connection with forward sale agreements (the “Forward Sale Agreements”) described below. The Offering closed on July 25, 2017. In connection with the Offering, the Company entered into separate Forward Sale Agreements with Morgan Stanley & Co. LLC and JPMorgan Chase Bank, National Association, London Branch (the “Forward Counterparties”) pursuant to which the Company has agreed to sell, and each Forward Counterparty agreed to purchase, 3 million shares of the Company’s common stock (or 6 million shares of the Company common stock in the aggregate) subject to the terms and conditions of the Forward Sale Agreements, including the Company’s right to elect cash settlement or net share settlement. The initial forward price under each of the Forward Sale Agreements is $58.08 per share (which is the public offering price of the Company’s common stock, less the underwriting discount) and is subject to certain adjustments pursuant to the terms of the Forward Sale Agreements. Settlement of each of the Forward Sale Agreements must occur no later than one year after the closing of the Offering but may occur earlier at the option of the Company or, in certain circumstances described in the Forward Sale Agreements, at the option of the relevant Forward Counterparty. A Forward Counterparty’s decision to exercise its right to accelerate the Forward Sale Agreements entered into with it and to require the Company to settle the Forward Sale Agreements will be made irrespective of the Company’s interests, including the Company’s need for capital. The Company could be required to issue and deliver the Company’s common stock under the terms of the physical settlement provisions of the Forward Sale Agreements irrespective of the Company’s capital needs, which would result in dilution to the Company’s earnings per share and return on equity. The Forward Sales Agreements are accounted for as equity instruments with subsequent changes in fair value not recognized as long as the contracts continue to be equity classified. The Company received proceeds of $290.4 million ($287.6 million net of fees and expenses) from the sale of 5 million shares of common stock in the Offering. The Company has not received any proceeds from the sale of shares of its common stock by the Forward Counterparties pursuant to the Forward Sale Agreements. The Company used the net proceeds of the shares issued and sold by the Company in the Offering and expects to use any net proceeds received upon the settlement of the Forward Sale Agreements for general corporate purposes, which may include strategic acquisitions and the repayment or refinancing of outstanding indebtedness. Series C Convertible Perpetual Preferred Stock and Common Stock In May 2015, the Company issued and sold 15.5 million shares (the “2015 Purchased Common Shares”) in the aggregate of the Company’s common stock, par value $0.001 per share (the “Company Common Stock”), and 0.6 million shares (the “2015 Purchased Preferred Stock” and, together with the 2015 Purchased Common Shares, the “2015 Purchased Securities”) in the aggregate of the Company’s Series C Convertible Perpetual Preferred Stock, par value $0.001 per share, in a private placement. The purchase price per 2015 Purchased Common Share was $45.00 (resulting in aggregate gross proceeds to the Company of approximately $697.5 million), and the purchase price per share of 2015 Purchased Preferred Stock was $1,000 (resulting in aggregate gross proceeds to the Company of approximately $562.5 million). The Company received net proceeds of $1,228.1 million after equity issuance costs which was initially allocated between common and preferred stock based on the relative fair values of each instrument. In September 2015, the 2015 Purchased Preferred Stock was automatically converted into 12.5 million shares of Company common stock. As the fair value of the Company’s common stock was greater than the conversion price, the conversion feature was issued “in-the-money” and the Company allocated the beneficial conversion feature of $52.0 million to additional paid-in capital. The beneficial conversion feature was recognized in net loss attributable to common shareholders upon receiving stockholder approval in September 2015.

Stock-Based Compensation

Stock-Based Compensation

On December 20, 2016, the Company’s stockholders approved the XPO Logistics, Inc. 2016 Omnibus Incentive Compensation Plan (the “2016 Plan”). The 2016 Plan replaces the XPO Logistics, Inc. Amended and Restated 2011 Omnibus Incentive Compensation Plan (the “2011 Plan”) and the Con-way Inc. 2012 Equity and Incentive Plan (the “Con-way Plan”), the latter of which was assumed by the Company in connection with the acquisition of Con-way. Any awards granted under the 2011 Plan and the Con-way Plan will remain in effect pursuant to their respective terms.

Under the terms of the 2016 Plan, the Company grants various types of stock-based compensation awards to directors, officers and key employees. The 2016 Plan provides for awards in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, deferred share units, performance compensation awards, performance units, cash incentive awards and other equity-based or equity-related awards (collectively, “Awards”) that the Compensation Committee of the Board of Directors (the “Committee”) determines are consistent with the purpose of the 2016 Plan and interests of the Company.

The maximum aggregate number of shares of common stock that may be delivered pursuant to Awards under the 2016 Plan is 3.4 million shares. Awards that are settled in cash would not reduce the number of shares available for delivery under the 2016 Plan. In the event of any extraordinary dividend or other extraordinary distribution, recapitalization, rights offering, stock split, reverse stock split, split-up or spin-off, the Committee shall equitably adjust any or all of the number of shares of the Company with respect to which Awards may be granted, including 2011 Plan share limits, the terms of any outstanding Award, the number of shares subject to outstanding Awards, and the exercise price of any Award, if applicable. Any shares delivered pursuant to an Award may consist, in whole or in part, of authorized and unissued shares or of treasury shares.

The 2016 Plan will continue in effect until December 20, 2026, unless terminated earlier by the Board of Directors. As of December 31, 2017, there were 2.5 million shares available for issuance under the 2016 Plan.

On December 20, 2017, the Company’s stockholders approved the XPO Logistics, Inc. Employee Stock Purchase Plan (the “ESPP”). Under the terms of the ESPP, all eligible employees in the U.S. can purchase common stock through payroll deductions (which cannot exceed 10 percent of each employee’s compensation) at 5 percent below fair market value on the last trading day at the end of each six-month purchase period during two offering periods per year, beginning on April 1 and October 1. Under the ESPP, employees must hold the stock they purchase for a minimum of three months from the date of purchase. Subject to adjustment for changes in the Company’s capitalization, the number of shares to be granted under the ESPP is not to exceed 2 million shares. The first offering period will occur in 2018 and the ESPP will be in effect until October 2027, unless terminated earlier at the discretion of the Board of Directors. The plan is deemed non-compensatory and therefore, no stock-based compensation expense will be recognized. Executive officers and directors of the Company are not eligible to participate in the ESPP.

The Company recognized the following stock-based compensation expense in Direct operating expense and SG&A in the Consolidated Statements of Operations:

The Company settled the outstanding warrants and certain performance stock awards of ND. The portion of the fair value of the warrants and performance shares not attributable to service performed prior to the acquisition date was recorded as stock-based compensation expense in 2015. The amount of stock-based compensation expense related to the settlement of ND stock awards included in the year ended December 31, 2015 was $18.5 million. The $8.5 million of stock-based compensation related to the warrants was settled in cash during the second quarter of 2015.

The Company settled all outstanding restricted stock awards as well as certain restricted stock units and performance-stock awards of Con-way. All remaining outstanding Con-way equity awards were assumed by the Company, as more fully discussed below. The portion of the fair value not attributable to service performed prior to the acquisition date was recorded as stock-based compensation expense in the post-combination period. The total value of the cash settlement of Con-way stock-based compensation awards in connection with the acquisition was $30.9 million, of which $17.8 million and $10.0 million was settled in cash during 2016 and 2015, respectively.

Stock Options

For employees and officers, stock options typically vest over three to five years after the grant date, have a ten year contractual term, and an exercise price equal to the Company’s stock price on the grant date. For grants to members of the Company’s Board of Directors, stock options vest one year after the grant date, have a ten year contractual term, and an exercise price equal to the Company’s stock price on the grant date.

In connection with the Con-way transaction, each outstanding Con-way stock option was converted into an equivalent intrinsic value of stock options with the same terms and conditions as were applicable prior to the acquisition, resulting in a total of 883,733 stock options assumed by the Company. All assumed stock options were fully vested as of the acquisition date.

The following is a summary of the weighted-average assumptions used to calculate the grant-date fair value using the Black-Scholes option pricing model. There were no stock options granted during 2017.



	2016		2015
Weighted-average risk-free interest rate	1.8	%	1.6	%
Weighted-average volatility	50.0	%	60.7	%
Weighted-average dividend yield	—		—
Weighted-average expected option term (in years)	6.44		6.61

The expected term of options granted has been derived based upon the Company’s history of actual exercise behavior and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon the Company’s historical market price at consistent points in a period equal to the expected life of the options. The risk-free interest rate is based on the U.S. Treasury yield curve with a term equal to the expected term of the option in effect at the time of grant.

A summary of stock option award activity for the year ended December 31, 2017 is presented below:



	Stock Options
	Number of Stock Options		Weighted-Average Exercise Price		Weighted-Average Remaining Term
Outstanding at December 31, 2016	1,080,554		$	13.32	5.21

Options exercisable at December 31, 2017	815,022		$	12.66	4.31

The weighted-average grant date fair value of options granted during 2016 and 2015 was $11.37 and $15.71, respectively. The intrinsic value of options outstanding and exercisable at December 31, 2017 was $66.8 million and $64.3 million, respectively. As of December 31, 2017, the Company had approximately $0.4 million of unrecognized compensation cost related to stock options which is expected to be recognized over a weighted-average period of one year.

The total intrinsic value of options exercised during 2017, 2016 and 2015 was $9.0 million, $11.7 million and $4.1 million, respectively. The total cash received from options exercised during 2017, 2016 and 2015 was $1.0 million, $13.2 million, and $5.2 million, respectively.

Restricted Stock Units and Performance-based Restricted Stock Units

The Company has granted RSUs and PRSUs to certain key employees, officers and directors of the Company with various vesting requirements as established by the Compensation Committee of the Board of Directors. The RSUs vest based on the passage of time. The vesting of certain RSU awards is also subject to the price of the Company’s common stock exceeding a specified per share price for a designated period of time and continued employment at the Company by the grantee as of the vesting date. The PRSUs granted will vest based on the achievement of certain targets with respect to the Company’s overall financial performance for specified periods. The vesting of certain PRSUs is also subject to the price of the Company’s common stock exceeding a specified per share price for a designated period of time and generally require continued employment at the Company by the grantee as of the vesting date.

The RSUs and PRSUs may vest in whole or in part before the applicable vesting date if the grantee’s employment is terminated by the Company without cause or by the grantee with good reason (as defined in the grant agreement), upon death or disability of the grantee or in the event of a change in control of the Company. Upon vesting, the RSUs and PRSUs result in the issuance of shares of XPO common stock after required minimum tax withholdings. The holders of the RSUs and PRSUs do not have the rights of a stockholder and do not have voting rights until certificates representing shares are issued and delivered in settlement of the awards. The fair value of all grants of RSUs and PRSUs subject to market-based vesting conditions was estimated using the Monte Carlo simulation lattice model.

A summary of RSU and PRSU award activity for the year ended December 31, 2017 is presented below:



	RSUs				PRSUs
	Number of RSUs		Weighted-Average Grant Date Fair Value		Number of PRSUs		Weighted-Average Grant Date Fair Value
Outstanding at December 31, 2016	977,820		$	26.60	2,266,556		$	20.88
Granted	658,222		51.05		283,887		51.67

Outstanding at December 31, 2017	1,041,554		$	41.96	1,838,227		$	24.37

The total fair value of RSUs vested during 2017, 2016 and 2015 was $23.0 million, $26.8 million and $14.3 million, respectively. Of the 1,041,554 outstanding RSUs, 1,029,840 vest subject to service conditions and 11,714 vest subject to service and market conditions.

The total fair value of PRSUs that vested during 2017, 2016 and 2015 was $8.4 million, $7.2 million and $0.7 million, respectively. Of the 1,838,227 outstanding PRSUs, 946,522 vest subject to service and a combination of market and performance conditions and 891,705 vest subject to service and performance conditions.

As of December 31, 2017, the Company had approximately $55.9 million of unrecognized compensation cost related to non-vested RSU and PRSU compensation that is anticipated to be recognized over a weighted-average period of approximately 2.21 years.

Cash-settled Performance-based Restricted Stock Units

In February 2016, the Company entered into employment agreements with its executive officers. Pursuant to these agreements, on February 9, 2016, the Company granted cash-settled PRSUs under the 2011 Plan to certain executive officers. Twenty-five percent of the PRSUs vest and are settled in cash on each of the first four anniversaries of the grant, subject to the grantee’s continued employment through the applicable anniversary and achievement of certain performance targets for each tranche. Cash-settled PRSU awards are measured at fair value initially based on the closing price of the Company’s common stock at the date of grant and are required to be re-measured to fair value at each reporting date until settlement. Compensation expense for cash-settled PRSUs is recognized over the applicable performance periods based on the probability of achieving the performance conditions and the closing price of the Company’s common stock at each balance sheet date. The Company records as a liability (until settlement) the cost of a cash-settled PRSU award for which achievement of the performance condition is deemed probable. At December 31, 2017 and 2016, the Company had recognized accrued liabilities of $51.7 million and $26.9 million, respectively, using a fair value per PRSU of $91.59 and $43.16, respectively.

A summary of cash-settled PRSU award activity for the year ended December 31, 2017 is presented below:



	Number of Cash-settled PRSUs
Outstanding at December 31, 2016	2,447,017
Granted	—
Vested	(622,733	)
Forfeited	(130,890	)
Outstanding at December 31, 2017	1,693,394

As of December 31, 2017, the Company had approximately $103.4 million of unrecognized compensation cost related to non-vested cash-settled PRSU compensation that is anticipated to be recognized over a weighted-average period of approximately 2.0 years and will vary based on changes in the Company’s common stock price and the probability of achieving performance targets in future periods.

On December 22, 2017, the “H.R.1”, formally known as the Tax Cuts and Jobs Act (the “Act”) was signed into law. The Act includes numerous changes to existing tax law, including a permanent reduction in the federal corporate income tax rate from 35% to 21%. The rate reduction is effective January 1, 2018. As a result, the Company recorded a tax benefit of $173.1 million in the fourth quarter of 2017 related to the revaluation of its net deferred tax liabilities. At this time, the Company has not made any adjustments related to potential Global Intangible Low-Taxed Income (“GILTI”) tax in its financial statements and has not made a policy decision regarding whether to record deferred taxes on GILTI. The Act also requires a one-time tax on the “mandatory deemed repatriation” of accumulated foreign earnings as of December 31, 2017. Based on provisional calculations, the Company does not expect to incur a tax liability on the mandatory repatriation. Based on a continued analysis of the estimates and further guidance on the application of the law, it is anticipated that additional revisions may occur throughout the allowable measurement period.

On December 31, 2017, a law was published in France enacting a rate reduction from 34.43% to 25.83% to be phased in over five years starting in 2018. On December 29, 2017, a law was published in Belgium enacting a tax rate reduction from 33.99% to 25% to be phased in over three years starting in 2018. Consequently, the Company recorded a tax benefit of $9.8 million in the fourth quarter of 2017 related to the revaluation of its net deferred tax liabilities.

Investments in Foreign Subsidiaries

The Act includes a mandatory one-time tax on accumulated earnings of foreign subsidiaries, and as a result, all previously unremitted earnings for which no U.S. deferred tax liability had been accrued have now been subject to U.S. tax. We intend to continue to invest all of these earnings, as well as our capital in these subsidiaries, indefinitely outside of the U.S. and do not expect to incur any significant taxes related to such amounts.

Operating Loss and Tax Credit Carryforwards

At December 31, 2017 and 2016, the Company had federal net operating losses for all U.S. operations (including those of minority owned subsidiaries) of $188.1 million and $284.4 million, respectively, expiring at various times between 2024 and 2037. At December 31, 2017 and 2016, the tax effect (before federal benefit) of the Company’s state net operating losses was $32.9 million and $38.2 million, respectively, expiring at various times between 2018 and 2038.

At December 31, 2017 and 2016, the Company had federal tax credit carryforwards of $34.4 million and $25.3 million, respectively, expiring at various times starting in 2032 with certain credits having an unlimited carryforward period. At December 31, 2017, the Company had state tax credit carryforwards of $9.6 million expiring at various times between 2018 and 2031. At December 31, 2016, the Company had state tax credit carryforwards of $4.2 million expiring at various times between 2017 and 2028.

At December 31, 2017 and 2016, the Company’s foreign net operating losses that are available to offset future taxable income were $332.3 million and $296.5 million, respectively. These foreign loss carryforwards will expire at various times beginning in 2018 with some losses having an unlimited carryforward period.

Valuation Allowance

The Company has evaluated the available positive and negative evidence and concluded, for some of its deferred tax assets, it is more likely than not that these assets will not be realized in the foreseeable future. Based on the Company’s assessment, as of December 31, 2017, total valuation allowances of $92.6 million were recorded against deferred tax assets. Although realization is not assured, the Company has concluded that it is more likely than not that the remaining deferred tax assets will be realized and as such no valuation allowance has been provided on these assets. The Company’s valuation allowance increased by $9.5 million during the year ended December 31, 2017.

The following table presents a rollforward of the valuation allowance for the years ended December 31, 2017, 2016, and 2015, respectively:



(In millions)	Balance at Beginning of Year		Additions		Reductions/Charges			Balance at End of Year
Valuation allowance
Year Ended December 31, 2017	$	83.1	$	29.0	$	(19.5	)	$	92.6

Unrecognized Tax Benefits (UTB)

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:



	Years Ended December 31,
(In millions)	2017			2016			2015
Beginning balance	$	14.6		$	11.5		$	6.2
Additions for tax positions of prior years	16.8			0.6			0.2

Total UTB that, if recognized, would impact the effective income tax rate as of the end of the year	$	22.8		$	11.4		$	8.1

During the next twelve months, it is reasonably possible that the Company could reflect a reduction to unrecognized tax benefits of $3.2 million due to the statute of limitations lapsing on positions or because tax positions are sustained on audit.

The Company is subject to taxation in the United States, various states, and foreign jurisdictions. As of December 31, 2017, the Company has no tax years under examination by the IRS. The Company has various U.S. state and local examinations and non-U.S. examinations in process. The U.S. Federal returns after 2010, state and local returns after 2009, and non-U.S. returns after 2007 are open under relevant statutes of limitations and are subject to audit.

Earnings Per Share [Abstract]

Earnings (Loss) per Share

Basic and diluted earnings (loss) per share are computed using the two-class method, which is an earnings allocation method that determines earnings (loss) per share for common shares and participating securities. The participating securities consist of the Company’s Series A Convertible Perpetual Preferred Stock. The undistributed earnings are allocated between common shares and participating securities as if all earnings had been distributed during the period. In periods of loss, no allocation is made to the preferred shares.

Commitments and Contingencies

Lease Commitments

Under operating leases, the Company is required to make payments for various real estate, double-stack railcars, containers, chassis, tractors, data processing equipment, transportation and office equipment leases that have an initial or remaining non-cancelable lease term. Certain leases also contain provisions that allow the Company to extend the leases for various renewal periods.

Under certain capital lease agreements, the Company guarantees the residual value of tractors at the end of the lease term. The stated amounts of the residual-value guarantees have been included in the minimum lease payments below.

Future minimum lease payments with initial or remaining non-cancelable lease terms in excess of one year, at December 31, 2017, were as follows:



(In millions)	Capital Leases			Operating Leases
Year ending December 31:
2018	$	50.0		$	517.9

Rent expense was approximately $716.3 million, $677.2 million and $412.1 million for the years ended December 31, 2017, 2016 and 2015, respectively.

Litigation

The Company is involved, and will continue to be involved, in numerous proceedings arising out of the conduct of its business. These proceedings may include, among other matters, claims for property damage or personal injury incurred in connection with the transportation of freight, claims regarding anti-competitive practices, and employment-related claims, including claims involving asserted breaches of employee restrictive covenants and tortious interference with contract. These proceedings also include numerous purported class action lawsuits, multi-plaintiff and individual lawsuits and state tax and other administrative proceedings that claim either that the Company’s owner operators or contract carriers should be treated as employees, rather than independent contractors, or that certain of the Company’s drivers were not paid for all compensable time or were not provided with required meal or rest breaks. These lawsuits and proceedings may seek substantial monetary damages (including claims for unpaid wages, overtime, failure to provide meal and rest periods, unreimbursed business expenses and other items), injunctive relief, or both.

The Company establishes accruals for specific legal proceedings when it is considered probable that a loss has been incurred and the amount of the loss can be reasonably estimated. Accruals for loss contingencies are reviewed quarterly and adjusted as additional information becomes available. In connection with certain acquisitions of privately-held businesses, the Company has retained purchase price holdbacks or escrows to provide security for a negotiated duration with respect to damages incurred in connection with pre-acquisition claims and litigation matters. If a loss is not both probable and reasonably estimable, or if an exposure to loss exists in excess of the amount accrued therefor or the applicable purchase price holdback or escrow, the Company assesses whether there is at least a reasonable possibility that a loss, or additional loss, may have been incurred. If there is a reasonable possibility that a loss, or additional loss, may have been incurred, the Company discloses the estimate of the possible loss or range of loss if it is material and an estimate can be made, or states that such an estimate cannot be made. The evaluation as to whether a loss is reasonably possible or probable is based on the Company’s assessment, in conjunction with legal counsel, regarding the ultimate outcome of the matter.

The Company believes that it has adequately accrued for, or has adequate purchase price holdbacks or escrows with respect to, the potential impact of loss contingencies that are probable and reasonably estimable. The Company does not believe that the ultimate resolution of any matters to which the Company is presently a party will have a material adverse effect on its results of operations, financial condition or cash flows. However, the results of these matters cannot be predicted with certainty, and an unfavorable resolution of one or more of these matters could have a material adverse effect on the Company’s financial condition, results of operations or cash flows. Legal costs incurred related to these matters are expensed as incurred.

The Company carries liability and excess umbrella insurance policies that it deems sufficient to cover potential legal claims arising in the normal course of conducting its operations as a transportation and logistics company. The liability and excess umbrella insurance policies generally do not cover the misclassification claims described in this Note. In the event the Company is required to satisfy a legal claim outside the scope of the coverage provided by insurance, the Company’s financial condition, results of operations or cash flows could be negatively impacted.

Intermodal Drayage Classification Claims

Certain of the Company’s intermodal drayage subsidiaries received notices from the California Labor Commissioner, Division of Labor Standards Enforcement (the “DLSE”), that a total of approximately 150 owner operators contracted with these subsidiaries filed claims in 2012 with the DLSE in which they assert that they should be classified as employees, rather than independent contractors. These claims seek reimbursement for the owner operators’ business expenses, including fuel, tractor maintenance and tractor lease payments. After a decision was rendered by a DLSE hearing officer in seven of these claims, in 2014, the Company appealed the decision to California Superior Court, San Diego, where a de novo trial was held on the merits of those claims. On July 17, 2015, the court issued a final statement of decision finding that the seven claimants were employees rather than independent contractors, and awarding an aggregate of $2.9 million plus post-judgment interest and attorneys’ fees to the claimants. The Company has exhausted its appeals in this matter and the Superior Court entered final judgment against the Company in January 2018. Separate decisions were rendered in June 2015 by a DLSE hearing officer in claims involving five additional plaintiffs, resulting in an award for the plaintiffs in an aggregate amount of approximately $0.9 million, following which the Company appealed the decisions in the U.S. District Court for the Central District of California. On May 16, 2017, the Court issued judgment finding that the five claimants were employees rather than independent contractors, and awarding an aggregate of approximately $1.0 million plus post-judgment interest and attorneys’ fees to the claimants. The Company has appealed this judgment, but cannot provide assurance that such appeal will be successful. In addition, separate decisions were rendered in April 2017 by a DLSE hearing officer in claims involving four additional plaintiffs, resulting in an award for the plaintiffs in an aggregate amount of approximately $0.9 million, which the Company has appealed to the California Superior Court, Long Beach. The remaining DLSE claims have been transferred to California Superior Court in three separate actions involving approximately 200 claimants, including the approximately 150 claimants mentioned above. The Company believes that it has adequately accrued for the potential impact of loss contingencies that are probable and reasonably estimable relating to the claims referenced above. The Company is unable at this time to estimate the amount of the possible loss or range of loss, if any, in excess of its accrued liability that it may incur as a result of these claims given, among other reasons, that the range of potential loss could be impacted substantially by future rulings by the courts involved, including on the merits of the claims.

Last Mile Logistics Classification Claims

Certain of the Company’s last mile logistics subsidiaries are party to several putative class action litigations brought by independent contract carriers who contracted with these subsidiaries in which the contract carriers assert that they should be classified as employees, rather than independent contractors. The particular claims asserted vary from case to case, but the claims generally allege unpaid wages, unpaid overtime, or failure to provide meal and rest periods, and seek reimbursement of the contract carriers’ business expenses. Putative class actions against the Company’s subsidiaries are pending, or have recently been settled, in California (Fernando Ruiz v. Affinity Logistics Corp., filed in May 2005, in the Federal District Court, Southern District of California - the Company has reached an agreement to settle this litigation, the court has granted final approval, and the Company has accrued the full amount of the settlement; and four related cases all pending in the Federal District Court, Northern District of California: Ron Carter, Juan Estrada, Jerry Green, Burl Malmgren, Bill McDonald and Joel Morales v. XPO Logistics, Inc., filed in March 2016; Ramon Garcia v. Macy’s and XPO Logistics Inc., filed in July 2016; Kevin Kramer v. XPO Logistics Inc., filed in September 2016; and Hector Ibanez v. XPO Last Mile, Inc., filed in May 2017); New Jersey (Leonardo Alegre v. Atlantic Central Logistics, Simply Logistics, Inc., filed in March 2015 in the Federal District Court, New Jersey and settled in November 2017); and Connecticut (Carlos Taveras v. XPO Last Mile, Inc., filed in November 2015 in the Federal District Court, Connecticut and settled in August 2017). The Company believes that it has adequately accrued for the potential impact of loss contingencies relating to the foregoing claims that are probable and reasonably estimable. The Company is unable at this time to estimate the amount of the possible loss or range of loss, if any, in excess of its accrued liability that it may incur as a result of these claims given, among other reasons, that the number and identities of plaintiffs in these lawsuits are uncertain and the range of potential loss could be impacted substantially by future rulings by the courts involved, including on the merits of the claims.

Last Mile TCPA Claims

The Company is a party to a putative class action litigation (Leung v. XPO Logistics, Inc., filed in May 2015 in the U.S. District Court, Illinois) alleging violations of the Telephone Consumer Protection Act (“TCPA”) related to an automated customer call system used by a last mile logistics business that the Company acquired. The Company has reached an agreement to resolve the Leung case and awaits final court approval of the settlement. The Company has accrued the full amount of the proposed settlement.

Less-Than-Truckload Meal Break Claims

The Company’s LTL subsidiary has been a party to class action litigation alleging violations of the state of California’s wage and hour laws, including alleged failure to provide its driver employees with required meal breaks and rest breaks. The primary case is Jose Alberto Fonseca Pina, et al. v. Con-way Freight Inc., et al. and was initially filed in November 2009 in Monterey County Superior Court and then removed to the U.S. District Court of California, Northern District. The Pina case was settled in November 2017 and the matter is now resolved.
