Principal Accounting Policies [Abstract]	'
Principal Accounting Policies	'
	Principal Accounting Policies
	Organization
	Con-way Inc. and its consolidated subsidiaries (“Con-way” or the “Company”) provide transportation, logistics and supply-chain management services for a wide range of manufacturing, industrial and retail customers. As more fully discussed in Note 12, “Segment Reporting,” for financial reporting purposes, Con-way is divided into three reporting segments: Freight, Logistics and Truckload.
	Principles of Consolidation
	The consolidated financial statements include the accounts of Con-way and its subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	Estimates
	Management makes estimates and assumptions when preparing the financial statements in conformity with accounting principles generally accepted in the U.S. These estimates and assumptions affect the amounts reported in the accompanying financial statements and notes. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates relate to revenue-related adjustments, impairment of goodwill and long-lived assets, amortization and depreciation, income taxes, self-insurance accruals, pension plan and postretirement obligations, contingencies, and assets and liabilities recognized in connection with acquisitions, restructurings and dispositions.
	Con-way evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Estimates and assumptions are adjusted when facts and circumstances dictate. Volatility in financial markets and changing levels of economic activity increase the uncertainty inherent in such estimates and assumptions. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
	Recognition of Revenue
	Con-way Freight recognizes revenue between reporting periods based on relative transit time in each period and recognizes expense as incurred. Estimates for future billing adjustments to revenue, including those related to weight and freight-classification verification and pricing discounts, are recognized at the time of shipment. Con-way Truckload recognizes revenue and related direct costs when the shipment is delivered. Menlo Worldwide Logistics ("Menlo") recognizes revenue based on the service outputs provided to the customer.
	Menlo records revenue on a gross basis, without deducting third-party purchased transportation costs, on transactions for which it acts as a principal. Menlo records revenue on a net basis, after deducting purchased transportation costs, on transactions for which it acts as an agent. When recognizing revenue for services provided under performance-based incentive arrangements, the contingent portion of the revenue is not considered fixed or determinable until the performance criteria have been met.
	Under certain Menlo contracts, billings in excess of revenue recognized are recorded as unearned revenue. Unearned revenue is recognized over the contract period as services are provided. At December 31, 2013 and 2012, unearned revenue of $12.1 million and $16.9 million was reported in Con-way’s consolidated balance sheets within accrued liabilities. In addition, Menlo 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. At December 31, 2013 and 2012, these deferred setup costs of $9.9 million and $15.2 million were reported in the consolidated balance sheets within deferred charges and other assets.
	Cash Equivalents and Marketable Securities
	Cash equivalents consist of short-term interest-bearing instruments with maturities of three months or less at the date of purchase. At December 31, 2013 and 2012, cash-equivalent investments of $441.2 million and $378.3 million consisted primarily of commercial paper, certificates of deposit and money-market funds.
	Con-way classifies its marketable debt securities as available-for-sale and reports them at fair value. Changes in the fair value of available-for-sale securities are recognized in other comprehensive income or loss, unless an unrealized loss is an other-than-temporary loss. If any portion of the unrealized loss is determined to be other than temporary, that portion of the loss is recognized in earnings. During 2013, Con-way liquidated all remaining variable-rate demand notes. At December 31, 2012, Con-way held $3.2 million of variable-rate demand notes.
	Trade Accounts Receivable, Net
	Con-way Freight and Con-way Truckload report accounts receivable at net realizable value and provide an allowance when losses are probable. Estimates for uncollectible accounts are based on various judgments and assumptions, including revenue levels, historical loss experience and the aging of outstanding accounts receivable. Menlo, based on the size and nature of its client base, performs a periodic evaluation of its customers’ creditworthiness and accounts receivable portfolio and recognizes expense from uncollectible accounts when losses are both probable and reasonably estimable. Activity in the allowance for uncollectible accounts is presented in the following table:
	(Dollars in thousands)			Additions

	2011	6,209		6,761		—		(6,019		)	6,951
	Estimates for billing adjustments, including those related to weight and freight-classification verifications and pricing discounts, are also reported as a reduction to accounts receivable. Activity in the allowance for revenue adjustments is presented in the following table:

	2011	14,291		—		86,853		(84,224		)	16,920
	Property, Plant and Equipment
	Property, plant and equipment are reported at historical cost and are depreciated primarily on a straight-line basis over their estimated useful lives, generally 25 years for buildings, 4 to 14 years for revenue equipment, and 3 to 10 years for most other equipment. Leasehold improvements and assets acquired under capital leases are amortized over the shorter of the terms of the respective leases or the useful lives of the assets, with the resulting expense reported as depreciation. Depreciation expense was $221.2 million in 2013, $204.9 million in 2012 and $191.4 million in 2011.
	In response to recent conditions in the used-trailer market, Con-way Truckload increased the estimated salvage values for certain of its trailers in the fourth quarter of 2013. This change decreased depreciation expense by $1.3 million in 2013 and is expected to decrease 2014 depreciation expense by $7.3 million.
	Expenditures for equipment maintenance and repairs are charged to operating expenses as incurred; betterments are capitalized. Gains or losses on sales of equipment and property are recorded in other operating expenses.
	Tires and Maintenance
	The cost of replacement tires are expensed at the time those tires are placed into service, as is the case with other repairs and maintenance costs. The cost of tires on new revenue equipment is capitalized and depreciated over the estimated useful life of the related equipment.
	Capitalized Software, Net
	Capitalized software consists of certain direct internal and external costs associated with internal-use software, net of accumulated amortization. Amortization of capitalized software is computed on an item-by-item basis depending on the estimated useful life of the software, currently between 3 years and 7 years. Amortization expense related to capitalized software was $7.2 million in 2013, $8.3 million in 2012, and $7.9 million in 2011. Accumulated amortization at December 31, 2013 and 2012 was $158.7 million and $155.9 million, respectively.
	Long-Lived Assets
	Con-way performs an impairment analysis of long-lived assets whenever circumstances indicate that the carrying amount may not be recoverable. For assets that are to be held and used, an impairment charge is recognized when the estimated undiscounted cash flows associated with the asset or group of assets is less than carrying value. If impairment exists, a charge is recognized for the difference between the carrying value and the fair value. Fair values are determined using quoted market values, discounted cash flows or external appraisals, as applicable. Assets held for disposal are carried at the lower of carrying value or estimated net realizable value. Con-way’s accounting policies for goodwill and other long-lived intangible assets are more fully discussed in Note 2, “Goodwill and Intangible Assets.”
	Book Overdrafts
	Book overdrafts represent outstanding drafts not yet presented to the bank that are in excess of recorded cash. These amounts do not represent bank overdrafts, which occur when drafts presented to the bank are in excess of cash in Con-way’s bank account, and would effectively be a loan to Con-way. At December 31, 2013 and 2012, book overdrafts of $40.8 million and $43.0 million, respectively, were included in accounts payable.
	Self-Insurance Accruals
	Con-way uses a combination of purchased insurance and self-insurance programs to provide for the costs of medical, casualty, liability, vehicular, cargo and workers’ compensation claims. The long-term portion of self-insurance accruals relates primarily to workers’ compensation and vehicular claims that are expected to be payable over several years. Con-way 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 the 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 materially affect actual costs paid to settle the claims and those amounts may be different than estimates.
	Con-way participates in a reinsurance pool to reinsure a portion of its workers’ compensation claims. Each company that participates in the pool cedes claims to the pool and assumes an equivalent amount of claims. Reinsurance does not relieve Con-way of its liabilities under the original policy. However, in the opinion of management, potential exposure to Con-way for non-payment is minimal. At December 31, 2013 and 2012, Con-way had recorded a liability related to assumed claims of $59.2 million and $65.0 million, respectively, and had recorded a receivable from the reinsurance pool of $38.1 million and $39.6 million, respectively. Revenue related to these reinsurance activities is reported net of the associated expenses and are classified as other operating expenses. In connection with its participation in the reinsurance pool, Con-way recognized operating income of $2.2 million in 2013, an operating loss of $2.5 million in 2012, and an operating loss of $4.4 million in 2011.
	Foreign Currency Translation
	Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are included in the foreign currency translation adjustment in the statements of consolidated comprehensive income (loss). Transaction gains and losses that arise from exchange-rate fluctuations on transactions denominated in a currency other than the functional currency are included in results of operations and are reported as miscellaneous, net in the statements of consolidated income.
	Con-way has determined that advances to certain of its foreign subsidiaries are indefinite in nature. Accordingly, the corresponding foreign currency translation gains or losses related to these advances are included in the foreign currency translation adjustment in the statements of consolidated comprehensive income (loss).
	Earnings Per Share (EPS)
	Basic EPS is computed by dividing reported net income or loss by the weighted-average common shares outstanding. Diluted EPS is calculated as follows:
	(Dollars in thousands, except per share data)	Years ended December 31,

New Accounting Standards
In March 2013, the FASB issued ASU 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU, codified in the "Foreign Currency Matters" topic of the FASB Accounting Standards Codification, resolves the differing views in practice about whether the deconsolidation guidance in the "Consolidation" topic of the FASB Accounting Standards Codification impacts the guidance in "Foreign Currency Matters" topic in regard to when to release the cumulative translation adjustment into earnings. Under this ASU, complete or substantially complete liquidation of the foreign entity is required to release the cumulative translation adjustment for transactions occurring within a foreign entity. However, for transactions impacting the parent's investments in a foreign entity, the cumulative translation adjustment should be released into earnings in a manner consistent with the deconsolidation guidance in the "Consolidation" topic. This accounting guidance in ASU 2013-05 will be applied prospectively and will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Con-way does not believe that the standard will have a material effect on its financial statements

	Con-way assesses goodwill for impairment on an annual basis in the fourth quarter, or more frequently if events or changes in circumstances indicate that the asset might be impaired.
	In connection with the annual impairment test in the fourth quarter of 2013, Con-way concluded that the goodwill of its reporting units was not impaired at December 31, 2013.
	Intangible Assets
	Intangible assets are amortized on a straight-line basis over their estimated useful life. Amortization expense related to intangible assets was $2.4 million in 2013, $3.0 million in 2012, and $3.3 million in 2011. Intangible assets consisted of the following:

	Purchase-Price Dispute
	Menlo Worldwide, LLC (“MW”) had asserted claims against the sellers of Chic Logistics, which MW acquired in 2007, alleging inaccurate books and records, misstatement of revenue, and other similar matters related to the pre-sale financial performance of Chic Logistics. In 2011, MW and the sellers entered into an agreement in which the sellers agreed to pay MW $10.0 million as an adjustment of the original purchase price to settle this dispute. MW received the full settlement amount in 2011 and recognized a corresponding gain of $10.0 million. The entire amount of goodwill associated with Chic Logistics had previously been written off.

	Fair-Value Measurements
	Assets and liabilities reported at fair value are classified in one of the following three levels within the fair-value hierarchy:
	Level 1: Quoted market prices in active markets for identical assets or liabilities
	Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data
	Level 3: Unobservable inputs that are not corroborated by market data
	Financial Assets Measured at Fair Value on a Recurring Basis

	Current marketable securities		3,200		—		3,200		—
	Cash equivalents consist of short-term interest-bearing instruments (primarily commercial paper, certificates of deposit and money market funds) with maturities of three months or less at the date of purchase. At December 31, 2012, current marketable securities consisted of variable-rate demand notes.
	Money-market funds reflect their published net asset value and are classified as Level 1 instruments. Commercial paper, certificates of deposit and variable-rate demand notes are generally valued using published interest rates for instruments with similar terms and maturities, and accordingly, are classified as Level 2 instruments. At December 31, 2013, the weighted-average remaining maturity of the cash equivalents was less than one month. Based on their short maturities, the carrying amount of the cash equivalents approximates their fair value.
	Level 3 investments consisted of one auction-rate security at December 31, 2011, which was valued with an income approach that utilized a discounted cash flow model. This investment was sold in the third quarter of 2012. The following table summarizes the change in fair value of Con-way's auction-rate security, which was valued using Level 3 inputs:

	Revolving Credit Facility
	Con-way has a $325 million revolving credit facility that matures on June 28, 2018. In 2013, Conway amended the credit facility to extend the maturity date from August 2, 2016 to June 28, 2018. The amended facility also includes revised pricing that lowers Con-way's cost of utilizing the facility. The financial covenants and available credit provided to Con-way under the facility are unchanged by the amendment.
	At December 31, 2013, no cash borrowings were outstanding under the credit facility; however, $109.3 million of letters of credit were outstanding, leaving $215.7 million of available capacity for additional letters of credit or cash borrowings, subject to compliance with financial covenants and other customary conditions to borrowing. The letters of credit outstanding at December 31, 2013 provided collateral for Con-way’s self-insurance programs.
	Under the agreement, standby letter of credit fees are equal to a margin that is dependent upon Con-way’s leverage ratio, and cash borrowings bear interest at a rate based upon LIBOR or the lead bank’s base rate, in each case plus a margin dependent on Con-way’s leverage ratio. The credit facility fee ranges from 0.18% to 0.35% applied to the total facility of $325 million based on Con-way’s leverage ratio. The revolving facility is guaranteed by certain of Con-way’s material domestic subsidiaries and contains two financial covenants: (i) a leverage ratio and (ii) a fixed-charge coverage ratio. There are also various restrictive covenants, including limitations on (i) the incurrence of liens, (ii) consolidations, mergers and asset sales, and (iii) the incurrence of additional subsidiary indebtedness.
	Other Credit Facilities and Short-term Borrowings
	At December 31, 2013, Con-way had $29.9 million of bank guarantees, letters of credit and overdraft facilities outstanding under other credit facilities.
	Con-way had short-term borrowings of $1.6 million and $7.0 million at December 31, 2013 and 2012, respectively. Excluding the non-interest bearing borrowings described below, the weighted-average interest rate on the short-term borrowings was 5.5% at December 31, 2012.
	Of the short-term borrowings outstanding at December 31, 2013 and 2012, non-interest bearing borrowings of $1.6 million and $4.2 million, respectively, related to a credit facility that Menlo utilizes for one of its logistics contracts. Borrowings under the facility related to amounts the financial institution paid to vendors on behalf of Menlo.
	7.25% Senior Notes due 2018
	The 7.25% Senior Notes bear interest at a rate of 7.25% per year, payable semi-annually on January 15 and July 15 of each year. Con-way may redeem the 7.25% Senior Notes, in whole or in part, on not less than 30 nor more than 60-days notice, at a redemption price equal to the greater of (i) the principal amount being redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the notes being redeemed, discounted at the redemption date on a semi-annual basis at the rate payable on a Treasury note having a comparable maturity plus 50 basis points. There are also various restrictive covenants, including limitations on (i) the incurrence of liens, and (ii) consolidations, mergers and asset sales. Including amortization of underwriting fees and related debt costs, interest expense on the 7.25% Senior Notes due 2018 is recognized at an annual effective interest rate of 7.37%.
	Holders of the 7.25% Senior Notes have the right to require Con-way to repurchase the notes if, upon the occurrence of both (i) a change in control, and (ii) a below investment-grade rating by any two of Moody’s, Standard and Poor’s or Fitch Ratings. The repurchase price would be equal to 101% of the aggregate principal amount of the notes repurchased plus any accrued and unpaid interest.
	6.70% Senior Debentures due 2034
	The $300 million aggregate principal amount of Senior Debentures bear interest at the rate of 6.70% per year, payable semi-annually on May 1 and November 1 of each year. Con-way may redeem the Senior Debentures, in whole or in part, on not less than 30 nor more than 60-days notice, at a redemption price equal to the greater of (i) the principal amount being redeemed, or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Senior Debentures being redeemed, discounted at the redemption date on a semi-annual basis at the rate payable on a Treasury note having a comparable maturity plus 35 basis points. The Senior Debentures were issued under an indenture that restricts Con-way’s ability, with certain exceptions, to incur debt secured by liens. Including amortization of a discount, interest expense on the 6.70% Senior Debentures Due 2034 is recognized at an annual effective interest rate of 6.90%.
	Other
	The aggregate annual maturities of long-term debt for the next five years ending December 31, are $0.6 million in 2016 and $425.0 million in 2018. Following 2018, Con-way does not have any principal payments due until 2034.
	As of December 31, 2013 and 2012, the estimated fair value of long-term debt was $806 million and $817 million, respectively. For the periods presented, long-term debt is classified as a Level 2 instrument with fair values estimated using broker-provided pricing.

	At December 31, 2013, Con-way had a federal tax loss carryforward of $41.5 million. This federal tax loss carryforward will fully expire in 2031. In addition to the federal tax loss carryforward, other carryforwards, including state tax credits, foreign taxes creditable against federal tax, and state and foreign tax losses, may create future benefits. The resulting benefit of the future use of all tax losses, including domestic and foreign, is $39.3 million while tax credit carryforwards provide a benefit of $10.0 million. Because Con-way does not anticipate that future state and foreign taxable income will allow realization of the full benefits, management concluded that these assets fail to meet the more-likely-than-not threshold for realization. These combined future tax benefits of $49.3 million, therefore, have been offset by a valuation allowance of $25.4 million.
	For all other deferred tax assets, management believes it is more likely than not that the results of future operations will generate taxable income of a sufficient amount and type to realize these deferred tax assets.
	Certain capital expenditures made between September 9, 2010 and December 31, 2013 were eligible for bonus depreciation, and in accordance with this provision of U.S. tax law, Con-way deducted a substantial portion of its capital expenditures made during the 2010 through 2013 tax years. Also, in January 2013, the American Taxpayer Relief Act of 2012 was enacted which extended the alternative-fuel credit to 2012 and 2013 tax years. Con-way recorded a discrete benefit of $3.3 million in the first quarter of 2013 to recognize the effect of the credit associated with the 2012 tax year. The alternative-fuel credit for the 2013 tax year was recognized over the course of 2013.
	No deferred taxes have been provided for the cumulative undistributed earnings of Con-way’s foreign subsidiaries ($29.9 million at December 31, 2013), which if remitted, are subject to withholding and U.S. taxes. Such amounts have been indefinitely reinvested in the respective foreign subsidiaries’ operations until it becomes advantageous for tax or foreign exchange reasons to remit these earnings. Determination of the amount of any unrecognized deferred income tax liability on this temporary difference is not practicable.
Income tax receivables of $10.6 million and $6.6 million were included in other accounts receivable in Con-way’s consolidated balance sheets at December 31, 2013 and 2012, respectively.
Uncertain Tax Positions
Con-way recognizes tax positions in the financial statements only when it is more likely than not that the position will be sustained upon examination by a taxing authority. If the position meets the more-likely-than-not criteria, it is measured using a probability-weighted approach as the largest amount of tax benefit that is greater than 50% likely of being realized upon settlement. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold are derecognized in the first subsequent financial reporting period in which the threshold is no longer met.
During 2012, the estimate for uncertain tax positions decreased to $15.0 million (including $5.3 million of accrued interest and penalties), primarily due to the lapse of statute of limitations and settlements with various taxing authorities, more fully discussed below. During 2013, the estimate decreased to $11.9 million (including $3.5 million of accrued interest and penalties), primarily due to the lapse of statute of limitations and settlements with various taxing authorities, more fully discussed below.
At December 31, 2013 and 2012, Con-way estimated that $6.5 million and $8.2 million, respectively, of the unrecognized tax benefits, if recognized, would change the effective tax rate. In 2013, a $1.8 million reversal of interest and penalties was included in income tax expense compared to $1.3 million in 2012.
The following summarizes the changes in the unrecognized tax benefits during the year, excluding interest and penalties:
(Dollars in thousands)

In the normal course of business, Con-way is subject to examination by taxing authorities throughout the world. As a result of these examinations, Con-way maintains ongoing discussions and negotiations relating to tax matters with the taxing authorities in these various jurisdictions.
Con-way is subject to examination for federal income taxes for tax years 2008 forward. In 2013, Con-way entered the Compliance Assurance Program (“CAP”). CAP is designed to make audits more effective, efficient and current such that when the federal tax return is filed it has been approved by the Internal Revenue Service ("IRS").
In 2012, the IRS finished its field audit of the 2008 through 2010 tax years and an issue emerged that resulted in an increase to the estimate for uncertain tax positions in 2012. Con-way settled this issue in 2013. Payment of the liability will occur in 2014.
In 2011, Con-way settled a disputed issue with the IRS that arose in the 2005 to 2007 audit cycle. This issue primarily related to the treatment and character of certain payments Con-way made to retirees and former employees of Menlo Worldwide Forwarding, Inc. and its subsidiaries (“MWF”) since the 2004 sale of MWF. Con-way and the IRS agreed in the settlement to re-characterize a portion of these payments as capital losses. The re-characterized portion may not be deducted, but may be used only to offset capital gains.
Con-way is also subject to examination by state, local, and foreign jurisdictions for 2003 to 2012. Con-way is currently under audit in many state and foreign tax jurisdictions, and management expects that, in the next 12 months, it is reasonably possible that the total of unrecognized tax benefits will decrease by $1.8 million. This decrease is primarily due to settlement agreements Con-way expects to reach with various tax authorities and by lapses of applicable statutes of limitations.

Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract]	'
Employee Benefit Plans	'
	Employee Benefit Plans
	In the periods presented, certain employees of Con-way and its subsidiaries in the U.S. were covered under several retirement benefit plans, including defined benefit pension plans, defined contribution retirement plans and a postretirement medical plan.
	Defined Benefit Pension Plans
	Con-way’s defined benefit pension plans include 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 IRC criteria. Con-way’s qualified defined benefit pension plans (collectively, the “Qualified Pension Plans”) consist mostly of a primary qualified defined benefit pension plan (the “Primary DB Plan”), which covers the non-contractual employees and former employees of Con-way’s continuing operations as well as former employees of its discontinued operations. Con-way’s other qualified defined benefit pension plans cover only the former employees of discontinued operations.
	Con-way's non-qualified defined benefit pension plans (collectively, the “Non-Qualified Pension Plans”) consist mostly of a primary non-qualified supplemental defined benefit pension plan (the “Supplemental DB Plan”). The Supplemental DB Plan provides additional benefits for certain employees who are affected by IRC limitations on compensation eligible for benefits available under the qualified Primary DB Plan.
	Some of Con-way's foreign subsidiaries sponsor defined benefit pension plans. These international defined benefit pension plans are excluded from the disclosures below due to their immateriality.
	Benefits
	As a result of plan amendments in previous years, no additional benefits accrue under these plans and already-accrued benefits will not be adjusted for future increases in compensation. In 2012, as a result of an actuarial equivalence review, Con-way amended its defined benefit pension plans, increasing the expected benefits to be paid.
	Funded Status of Defined Benefit Pension Plans
	The following table reports the changes in the projected benefit obligation, the fair value of plan assets and the determination of the amounts recognized in the consolidated balance sheets for Con-way’s defined benefit pension plans at December 31:

Plan Assets
Investment Policies and Strategies
Assets of the Qualified Pension Plans are managed pursuant to a long-term allocation strategy that seeks to mitigate the Plans' funded status volatility by increasing the Plans' 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 of the Qualified Pension Plans. In 2013, the Plans lowered their percentage of investments in equity securities and increased their percentage of investments in fixed-income securities.
The Plans' current investment strategy is to achieve a mix of approximately 69% in fixed-income securities and 31% of investments in equity securities by the end of 2014. Investments in fixed-income securities consist primarily of high-quality U.S. corporate or government debt instruments in a variety of industries. The target allocations for equity securities include 16% in U.S. large companies, 3% in U.S. small companies, and 12% in international companies. Investments in equity securities are allocated between growth- and value-style investment strategies and are diversified across industries and investment managers. The Plans’ investments in fixed-income and equity securities consist of individual securities held in managed separate accounts as well as commingled investment funds.
The Plans' investment strategy does not include a meaningful long-term investment allocation to cash and cash equivalents; however, the Plan's cash allocation may rise periodically in response to timing considerations regarding contributions, investments, and the payment of benefits and eligible plan expenses. Additionally, the level of cash and cash equivalents may reflect the un-invested balance of each manager's allocated portfolio balance. This “un-invested cash” is typically held in a short-term fund that invests in money-market instruments, including commercial paper and other liquid short-term interest-bearing instruments.
The Plans' 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. Con-way's investment policies also restrict the investment managers from accumulating concentrations by issuer, country or industry segment. The assumption of 6.53% for the overall expected long-term rate of return in 2014 was developed using asset allocation, return, risk (defined as standard deviation), and correlation expectations. The return expectations are created using long-term historical returns and current market expectations for inflation, interest rates and economic growth.

Funding
Con-way's funding practice is to evaluate its tax and cash position, as well as the Qualified Pension Plans' funded status, in determining its planned contributions. Con-way estimates that it will contribute $59 million to its Qualified Pension Plans in 2014; however, this could change based on variations in interest rates, asset returns, Pension Protection Act requirements and other factors.
Defined Contribution Retirement Plans
Con-way’s cost for defined contribution retirement plans was $55.3 million in 2013, $50.8 million in 2012, and $38.4 million in 2011. In the fourth quarter of 2011, Con-way reinstated certain contributions to its defined contribution retirement plans to their prior levels that had previously been suspended in the second quarter of 2009 as part of a cost-savings initiative. In the first quarter of 2013, additional contributions were implemented for employees hired on or after January 1, 2010. In the periods presented, Con-way’s contributions included cash and Con-way common stock. From January 2009 through June 2011, the common stock contributions were made with repurchased common stock (also referred to as treasury stock). In 2011, Con-way used 461,151 shares of treasury stock to fund $17.3 million in contributions.
Postretirement Medical Plan
Con-way 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.
On October 31, 2013, Con-way amended the Postretirement Plan to provide a set benefit to certain retirees, at least 65 years of age, effective in 2014. Accordingly, a remeasurement was performed, reducing the projected benefit obligation by $28.3 million with an offsetting prior-service credit of $19.2 million and an actuarial gain of $9.1 million recognized in other comprehensive income (loss).

Share-Based Compensation	'
	Share-Based Compensation
	Under terms of its share-based compensation plans, Con-way grants various types of share-based compensation awards to employees and directors. The plans provide for awards in the form of nonvested stock (also known as restricted stock), performance-share plan units ("PSPUs"), stock options and stock appreciation rights (“SARs”).
	Con-way recognizes expense on a straight-line basis over the shorter of (1) the requisite service period stated in the award or (2) the period from the grant date of the award up to the employee’s retirement-eligibility date if the award contains an accelerated-vesting provision. Awards with graded-vesting terms recognize expense on a straight-line basis over the requisite service period for the entire award. The following expense was recognized for share-based compensation:
	(Dollars in thousands)	Years ended December 31,
		2013				2012				2011
	Salaries, wages and employee benefits	$	20,783			$	14,464			$	12,764
	Deferred income tax benefit	(8,090		)		(5,616		)		(4,935		)
	Net share-based compensation expense	$	12,693			$	8,848			$	7,829
	The fair value of each stock option and SAR grant is estimated using the Black-Scholes option-pricing model, which considers the risk-free interest rate, and the expected award term, volatility and dividend yield. The risk-free interest rate is determined using the U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the award. The expected term of the award is derived from a binomial lattice model, and is based on the historical rate of voluntary exercises, post-vesting terminations and volatility. Expected volatility is based on the historical volatility of Con-way’s common stock over the most recent period equal to the expected term of the award.
	The Board of Directors authorized the issuance of 7,637,432 shares of common stock for the grant of stock options, nonvested stock or other share-based compensation under its equity plans, of which 3,391,554 were available at December 31, 2013.
	Nonvested Stock
	Awards granted to directors prior to 2012 generally have three-year graded-vesting terms, while those granted in 2012 and after generally vest one year from the award date. Awards granted to employees generally vest three years from the award date. Nonvested stock awards provide for accelerated vesting as a result of a change in control, death or disability (as defined in the award agreement). The awards allow for pro-rata vesting if the award recipient leaves Con-way due to a qualifying retirement during the vesting period. Shares of nonvested stock that are eligible for dividends are valued at the market price of Con-way's common stock at the date of the award. Those awards that are not eligible for dividends are valued at the market price of Con-way’s common stock at the date of award, reduced by the present value of the dividends not received during the vesting period.
	The following table summarizes nonvested stock activity for 2013:
		Number of			Weighted-
		Awards			Average
					Grant-Date
					Fair Value
	Outstanding at December 31, 2012	817,319			$	31.25
	Awarded – Employees	294,997			33.19
	Awarded – Directors	28,900			34.6
	Vested	(275,257	)		30.88
	Forfeited	(42,889	)		31.83
	Outstanding at December 31, 2013	823,070			$	32.15
	The weighted-average grant-date fair value per share for nonvested stock awards granted to employees in 2012 and 2011 was $30.37 and $32.41, respectively. The weighted-average grant-date fair value per share for nonvested stock awards granted to directors in 2012 and 2011 was $33.75 and $38.11, respectively.
	The total fair value of nonvested stock that vested in 2013, 2012 and 2011 was $9.4 million, $11.0 million and $5.4 million, respectively, based on Con-way’s closing common stock price on the vesting date. At December 31, 2013, the total unrecorded deferred compensation cost of shares of nonvested stock, net of forfeitures, was $10.5 million, which is expected to be recognized over a weighted-average period of 1.72 years.
	Performance-share Plan Units
	The PSPUs vest three years from the grant date if certain performance criteria are achieved. The number of shares the award recipients ultimately receive can range from 0% to 200% of the grant target depending on achievement relative to the performance criteria. PSPUs are subject to forfeiture if any award recipient ceases to be an active full-time employee prior to the end of the three-year period, subject in some cases to early vesting upon specified events, including death or disability of the award recipient, or termination of employment following a change in control of Con-way. The awards allow for pro-rata vesting if the award recipient leaves Con-way due to a qualifying retirement during the vesting period. The PSPUs are valued at the market price of Con-way's common stock at the date of the award, reduced by the present value of the dividends not received during the three-year vesting period. The amount of expense recorded each period is based on Con-way's current estimate of the number of shares that will ultimately vest.
	The following table summarizes PSPU activity for 2013:
		Number of			Weighted-
		Awards			Average
					Grant-Date

	Outstanding at December 31, 2012	235,984			$	29.67

	Outstanding at December 31, 2013	437,015			$	31.02
	The weighted-average grant-date fair value per share for PSPUs granted in 2012 was $29.67.
	At December 31, 2013, the total unrecorded deferred compensation cost of shares of PSPUs, net of forfeitures, was $8.2 million, which is expected to be recognized over a weighted-average period of 1.78 years.
	Stock Options
	Stock options are granted at prices equal to the market value of the common stock on the date of grant and expire 10 years from the date of grant. Stock options are granted with three-year graded-vesting terms, under which one-third of the award vests each year. Certain option awards provide for accelerated vesting as a result of a change in control, qualifying retirement, death or disability (as defined in the stock option plans).

Stock Appreciation Rights
The cash-settled SARs were granted at the stock price on the grant date and have a three-year graded-vesting term. The awards provide for accelerated vesting if the employee ceases employment due to retirement, death, disability, or a change in control (as defined in the SAR agreement). The SARs were granted in 2010 and became fully vested in January 2013. During the vesting period, compensation cost was recognized based on the proportionate amount of service rendered to date. The SARs are liability-classified awards and, as a result, Con-way re-measures the fair value of the awards each reporting period until the awards are settled. Con-way will recognize any changes in fair value after the vesting period as compensation cost in the current period. The ultimate expense recognized for the SARs is equal to the intrinsic value at settlement. Con-way’s accrued liability for cash-settled SARs of $4.3 million and $3.6 million at December 31, 2013 and 2012 was determined using a weighted-average fair value of $15.13 and $7.43 per SAR at December 31, 2013 and 2012 respectively.

Commitments And Contingencies	'
	Service Contracts
	Con-way has agreements with third-party service providers to provide certain information-technology, administrative and accounting services. The payments under the terms of the agreements are subject to change depending on the quantities and types of services consumed. The contracts also contain provisions that allow Con-way to terminate the contract at any time; however, Con-way would be required to pay fees if termination is for causes other than the failure of the service providers to perform.
	California Wage and Hour
	Con-way is a defendant in several class-action lawsuits alleging violations of the state of California's wage and hour laws. Plaintiffs allege that Con-way failed to pay certain drivers for all compensable time and that certain other drivers were not provided with required meal breaks and rest breaks. Plaintiffs seek to recover unspecified monetary damages, penalties, interest and attorneys' fees. The two primary cases are Jorge R. Quezada v. Con-way Inc., dba Con-way Freight, (the "Quezada" case), and Jose Alberto Fonseca Pina, et al. v. Con-way Freight Inc., et al. (the "Pina" case). The Quezada case was initially filed in February 2009 in San Mateo County Superior Court, and was removed to the U.S. District Court of California, Northern District. The Pina case was initially filed in November 2009 in Monterey County Superior Court and was removed to the U.S. District Court of California, Northern District. By agreement of the parties, in March 2010, the Pina case and the Quezada case were deemed related and transferred to the same judge. On April 12, 2012, the Court granted plaintiff's request for class certification in the Pina case as to a limited number of issues. On October 15, 2012, the Court granted plaintiffs' request for class certification in the Quezada case and granted summary judgment as to certain issues. The class certification rulings do not address whether Con-way will ultimately be held liable. In the Quezada case, trial is currently scheduled for April 2014.
	Con-way continues to challenge the certification of the class in both cases, and further contends that plaintiffs' claims are pre-empted by federal law and not substantiated by the facts. Con-way has denied any liability with respect to these claims and intends to vigorously defend itself in these cases. There are multiple factors that prevent Con-way from being able to estimate the amount of potential loss, if any, in excess of its accrued liability that may result from this matter, including: (1) Con-way is vigorously defending itself and believes that it has a number of meritorious legal defenses; and (2) at this early stage in the cases, there are unresolved questions of fact that could be important to the resolution of these matters. Accordingly, Con-way cannot estimate the amount or range of potential loss, if any, in excess of its accrued liability.
	Menlo Receivable Dispute
	Menlo filed for and received an asset preservation order from the Ningxia High Court in China in April of 2013 in connection with an unpaid accounts receivable balance. The order secures the customer's assets for the equivalent unpaid accounts receivable balance. Following the customer's failure to pay $6.1 million within agreed-upon terms, Menlo, in the fourth quarter of 2012, became less confident of its ability to collect the full amount of the outstanding receivable balance. As a result, Menlo recorded an allowance of $2.3 million in the fourth quarter of 2012. In connection with that action, Menlo seized coal inventory and the customer provided two shareholders' personal guarantees to Menlo in the event the customer fails to pay any or all the unpaid accounts receivable balance after selling all its assets, including the coal inventory. In the second quarter of 2013, new information came to Menlo's attention that caused Menlo to question whether it could continue to recognize any portion of the outstanding receivable balance, including information that raised uncertainty regarding Menlo's ability to realize value from the sale of secured assets of the customer. Accordingly, Menlo wrote off the entire receivable in June 2013. Any proceeds from the sales of any customer assets will be recognized in future periods when and if they occur.
	Unclaimed-Property Audits
	Con-way is currently being audited by eight states, primarily the State of Delaware, for compliance with unclaimed-property laws. The property subject to review in this audit process generally includes unclaimed securities and unclaimed payments and refunds to employees, vendors and customers. State and federal escheat laws generally require companies to report and remit unclaimed property to the states. Con-way believes it has procedures in place to comply with these laws. The audits of Con-way securities were completed in the third quarter of 2013 with no material findings and the remaining audits will continue into 2014. Given the current stage of the remaining audits, Con-way cannot estimate the amount or range of potential loss, if any.
	Other
	Con-way is a defendant in various other lawsuits incidental to its businesses. It is the opinion of management that the ultimate outcome of these actions will not have a material effect on Con-way’s financial condition, results of operations or cash flows.

Segment Reporting [Abstract]	'
Segment Reporting	'
	Con-way discloses segment information in the manner in which the business units are organized for making operating decisions, assessing performance and allocating resources. For the periods presented, Con-way is divided into the following three reporting segments:
	•	Freight. The Freight segment consists of the operating results of the Con-way Freight business unit, which provides regional, inter-regional and transcontinental less-than-truckload freight services throughout North America.
	•	Logistics. The Logistics segment consists of the operating results of the Menlo business unit, which develops contract-logistics solutions, including the management of complex distribution networks and supply-chain engineering and consulting, and also provides multimodal freight-brokerage services.
	•	Truckload. The Truckload segment consists of the operating results of the Con-way Truckload business unit, which provides asset-based full-truckload freight services throughout North America.
	In prior years, the Other reporting segment consisted of the operating results of Con-way's trailer manufacturer and certain corporate activities for which the related income or expense was not allocated to other reporting segments. Beginning in the first quarter of 2013, the former Other segment is reported as Corporate and Eliminations in order to reconcile the segment results to the consolidated totals. All years presented reflect this change to the reporting segment structure.
	Financial Data
	Management evaluates segment performance primarily based on revenue and operating income (loss). Accordingly, investment income, interest expense, and other non-operating items are not reported in segment results. Corporate expenses are generally allocated based on measurable services provided to each segment, or for general corporate expenses, based on segment revenue. Beginning in the first quarter of 2013, defined benefit pension plan costs are no longer allocated from Corporate to the reporting segments. The amount of defined benefit pension cost retained in Corporate and Eliminations was $4.2 million in 2013. In prior periods, the amount of defined benefit pension cost allocated from Corporate to the three reporting segments was $9.6 million in 2012 and $0.4 million in 2011. Inter-segment revenue and related operating income (loss) have been eliminated to reconcile to consolidated revenue and operating income. Transactions between segments are generally based on negotiated prices.

Principles Of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of Con-way and its subsidiaries. All significant intercompany accounts and transactions have been eliminated.
Estimates	'
	Estimates
	Management makes estimates and assumptions when preparing the financial statements in conformity with accounting principles generally accepted in the U.S. These estimates and assumptions affect the amounts reported in the accompanying financial statements and notes. Changes in estimates are recognized in accordance with the accounting rules for the estimate, which is typically in the period when new information becomes available. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Such estimates relate to revenue-related adjustments, impairment of goodwill and long-lived assets, amortization and depreciation, income taxes, self-insurance accruals, pension plan and postretirement obligations, contingencies, and assets and liabilities recognized in connection with acquisitions, restructurings and dispositions.
	Con-way evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment. Estimates and assumptions are adjusted when facts and circumstances dictate. Volatility in financial markets and changing levels of economic activity increase the uncertainty inherent in such estimates and assumptions. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods.
Recognition Of Revenues	'
	Recognition of Revenue
	Con-way Freight recognizes revenue between reporting periods based on relative transit time in each period and recognizes expense as incurred. Estimates for future billing adjustments to revenue, including those related to weight and freight-classification verification and pricing discounts, are recognized at the time of shipment. Con-way Truckload recognizes revenue and related direct costs when the shipment is delivered. Menlo Worldwide Logistics ("Menlo") recognizes revenue based on the service outputs provided to the customer.
	Menlo records revenue on a gross basis, without deducting third-party purchased transportation costs, on transactions for which it acts as a principal. Menlo records revenue on a net basis, after deducting purchased transportation costs, on transactions for which it acts as an agent. When recognizing revenue for services provided under performance-based incentive arrangements, the contingent portion of the revenue is not considered fixed or determinable until the performance criteria have been met.
	Under certain Menlo contracts, billings in excess of revenue recognized are recorded as unearned revenue. Unearned revenue is recognized over the contract period as services are provided. At December 31, 2013 and 2012, unearned revenue of $12.1 million and $16.9 million was reported in Con-way’s consolidated balance sheets within accrued liabilities. In addition, Menlo 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. At December 31, 2013 and 2012, these deferred setup costs of $9.9 million and $15.2 million were reported in the consolidated balance sheets within deferred charges and other assets.
Cash Equivalents And Marketable Securities	'
	Cash Equivalents and Marketable Securities
	Cash equivalents consist of short-term interest-bearing instruments with maturities of three months or less at the date of purchase. At December 31, 2013 and 2012, cash-equivalent investments of $441.2 million and $378.3 million consisted primarily of commercial paper, certificates of deposit and money-market funds.
	Con-way classifies its marketable debt securities as available-for-sale and reports them at fair value. Changes in the fair value of available-for-sale securities are recognized in other comprehensive income or loss, unless an unrealized loss is an other-than-temporary loss. If any portion of the unrealized loss is determined to be other than temporary, that portion of the loss is recognized in earnings. During 2013, Con-way liquidated all remaining variable-rate demand notes. At December 31, 2012, Con-way held $3.2 million of variable-rate demand notes.

Trade Accounts Receivable, Net	'
	Trade Accounts Receivable, Net
	Con-way Freight and Con-way Truckload report accounts receivable at net realizable value and provide an allowance when losses are probable. Estimates for uncollectible accounts are based on various judgments and assumptions, including revenue levels, historical loss experience and the aging of outstanding accounts receivable. Menlo, based on the size and nature of its client base, performs a periodic evaluation of its customers’ creditworthiness and accounts receivable portfolio and recognizes expense from uncollectible accounts when losses are both probable and reasonably estimable. Activity in the allowance for uncollectible accounts is presented in the following table:

Property, Plant And Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment are reported at historical cost and are depreciated primarily on a straight-line basis over their estimated useful lives, generally 25 years for buildings, 4 to 14 years for revenue equipment, and 3 to 10 years for most other equipment. Leasehold improvements and assets acquired under capital leases are amortized over the shorter of the terms of the respective leases or the useful lives of the assets, with the resulting expense reported as depreciation. Depreciation expense was $221.2 million in 2013, $204.9 million in 2012 and $191.4 million in 2011.
	In response to recent conditions in the used-trailer market, Con-way Truckload increased the estimated salvage values for certain of its trailers in the fourth quarter of 2013. This change decreased depreciation expense by $1.3 million in 2013 and is expected to decrease 2014 depreciation expense by $7.3 million.
	Expenditures for equipment maintenance and repairs are charged to operating expenses as incurred; betterments are capitalized. Gains or losses on sales of equipment and property are recorded in other operating expenses.
Tires	'
	Tires and Maintenance
	The cost of replacement tires are expensed at the time those tires are placed into service, as is the case with other repairs and maintenance costs. The cost of tires on new revenue equipment is capitalized and depreciated over the estimated useful life of the related equipment.
Capitalized Software, Net	'
	Capitalized Software, Net
	Capitalized software consists of certain direct internal and external costs associated with internal-use software, net of accumulated amortization. Amortization of capitalized software is computed on an item-by-item basis depending on the estimated useful life of the software, currently between 3 years and 7 years. Amortization expense related to capitalized software was $7.2 million in 2013, $8.3 million in 2012, and $7.9 million in 2011. Accumulated amortization at December 31, 2013 and 2012 was $158.7 million and $155.9 million, respectively.
Long-Lived Assets	'
	Long-Lived Assets
	Con-way performs an impairment analysis of long-lived assets whenever circumstances indicate that the carrying amount may not be recoverable. For assets that are to be held and used, an impairment charge is recognized when the estimated undiscounted cash flows associated with the asset or group of assets is less than carrying value. If impairment exists, a charge is recognized for the difference between the carrying value and the fair value. Fair values are determined using quoted market values, discounted cash flows or external appraisals, as applicable. Assets held for disposal are carried at the lower of carrying value or estimated net realizable value. Con-way’s accounting policies for goodwill and other long-lived intangible assets are more fully discussed in Note 2, “Goodwill and Intangible Assets.”
Book Overdrafts	'
	Book Overdrafts
	Book overdrafts represent outstanding drafts not yet presented to the bank that are in excess of recorded cash. These amounts do not represent bank overdrafts, which occur when drafts presented to the bank are in excess of cash in Con-way’s bank account, and would effectively be a loan to Con-way. At December 31, 2013 and 2012, book overdrafts of $40.8 million and $43.0 million, respectively, were included in accounts payable.
Self-Insurance Accruals	'
	Self-Insurance Accruals
	Con-way uses a combination of purchased insurance and self-insurance programs to provide for the costs of medical, casualty, liability, vehicular, cargo and workers’ compensation claims. The long-term portion of self-insurance accruals relates primarily to workers’ compensation and vehicular claims that are expected to be payable over several years. Con-way 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 the 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 materially affect actual costs paid to settle the claims and those amounts may be different than estimates.
	Con-way participates in a reinsurance pool to reinsure a portion of its workers’ compensation claims. Each company that participates in the pool cedes claims to the pool and assumes an equivalent amount of claims. Reinsurance does not relieve Con-way of its liabilities under the original policy. However, in the opinion of management, potential exposure to Con-way for non-payment is minimal. At December 31, 2013 and 2012, Con-way had recorded a liability related to assumed claims of $59.2 million and $65.0 million, respectively, and had recorded a receivable from the reinsurance pool of $38.1 million and $39.6 million, respectively. Revenue related to these reinsurance activities is reported net of the associated expenses and are classified as other operating expenses. In connection with its participation in the reinsurance pool, Con-way recognized operating income of $2.2 million in 2013, an operating loss of $2.5 million in 2012, and an operating loss of $4.4 million in 2011.
Foreign Currency Translation	'
	Foreign Currency Translation
	Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are included in the foreign currency translation adjustment in the statements of consolidated comprehensive income (loss). Transaction gains and losses that arise from exchange-rate fluctuations on transactions denominated in a currency other than the functional currency are included in results of operations and are reported as miscellaneous, net in the statements of consolidated income.
	Con-way has determined that advances to certain of its foreign subsidiaries are indefinite in nature. Accordingly, the corresponding foreign currency translation gains or losses related to these advances are included in the foreign currency translation adjustment in the statements of consolidated comprehensive income (loss).

New Accounting Standards	'
	New Accounting Standards
	In March 2013, the FASB issued ASU 2013-05, "Parent's Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity." This ASU, codified in the "Foreign Currency Matters" topic of the FASB Accounting Standards Codification, resolves the differing views in practice about whether the deconsolidation guidance in the "Consolidation" topic of the FASB Accounting Standards Codification impacts the guidance in "Foreign Currency Matters" topic in regard to when to release the cumulative translation adjustment into earnings. Under this ASU, complete or substantially complete liquidation of the foreign entity is required to release the cumulative translation adjustment for transactions occurring within a foreign entity. However, for transactions impacting the parent's investments in a foreign entity, the cumulative translation adjustment should be released into earnings in a manner consistent with the deconsolidation guidance in the "Consolidation" topic. This accounting guidance in ASU 2013-05 will be applied prospectively and will be effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Con-way does not believe that the standard will have a material effect on its financial statements

	[a]	These funds are not publicly traded and do not have readily determinable fair values. Accordingly, they are valued at their net asset value per share. The underlying investments in the funds consist primarily of publicly traded securities with quoted market prices.
	[b]	Gains from S&P 500 futures held in a separately managed account.
	[c]	Publicly traded equity securities are valued at their closing market prices.
	[d]	U.S. government securities are valued at their quoted market price, while corporate-debt instruments are generally valued using observable bid-ask spreads or broker-provided pricing.
	[e]	The fair value of the private real estate fund is based on the fair values of the underlying assets, which consist of commercial and residential properties valued using periodic appraisals. The fund maintains a redemption plan whereby redemption requests must be received in writing 45 days prior to the end of the quarter. If the fund is unable to satisfy all redemption requests, partial redemptions may be made on a prorated basis.
	[f]	The fair value of the hedge fund is based on the fair value of the underlying assets, which consists of individual equities, convertible securities, futures, forward contracts, currency forwards, swaps, high-yield debt portfolios, options, other derivative instruments, and cash which are all valued monthly.
