	Note 1 - Basis of Presentation
	On June 30, 2014, TimkenSteel Corporation (TimkenSteel) became an independent company as a result of the distribution by The Timken Company (Timken) of 100 percent of the outstanding common shares of TimkenSteel to Timken shareholders (the spinoff). Each Timken shareholder of record as of the close of business on June 23, 2014 (the Record Date) received one TimkenSteel common share for every two Timken common shares held as of the Record Date. The spinoff was completed on June 30, 2014 and was structured to be tax-free to both Timken and TimkenSteel shareholders. Settlement of the transfer of assets and liabilities between Timken and TimkenSteel is expected to be finalized in the second half of 2014.
	On July 1, 2014, TimkenSteel common shares began regular trading on the New York Stock Exchange under the ticker symbol “TMST”. Pursuant to the separation and distribution agreement with Timken, on June 30, 2014, TimkenSteel made a special cash dividend to Timken of $50.0 million.
	TimkenSteel manufactures alloy steel, as well as carbon and micro-alloy steel, with an annual melt capacity of approximately 2 million tons. TimkenSteel’s portfolio includes special bar quality (SBQ) bars, seamless mechanical tubing and precision steel components. In addition, TimkenSteel supplies machining and thermal treatment services and manages raw material recycling programs, which is done as a feeder system for TimkenSteel’s operations.
	Prior to the spinoff on June 30, 2014, TimkenSteel operated as a reportable segment within Timken. The accompanying Unaudited Consolidated Financial Statements have been prepared from Timken’s historical accounting records and are presented on a stand-alone basis as if the operations had been conducted independently from Timken. Accordingly, Timken and its subsidiaries net investment in these operations (Parent Equity) is shown in lieu of stockholder’s equity in the Unaudited Consolidated Financial Statements. The Unaudited Consolidated Financial Statements include the historical results of operations, assets and liabilities of the legal entities that are considered to comprise TimkenSteel. The historical results of operations, financial position, and cash flows of TimkenSteel presented in the Unaudited Consolidated Financial Statements may not be indicative of what they would have been had TimkenSteel actually been a separate stand-alone entity during such periods, nor are they necessarily indicative of TimkenSteel’s future results of operations, financial position and cash flows.
	The accompanying Unaudited Consolidated Financial Statements for TimkenSteel have been prepared for the six months ended June 30, 2014 and do not include all of the information and notes required by the accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) and disclosures considered necessary for a fair presentation have been included. For further information, refer to TimkenSteel’s Audited Consolidated Financial Statements for the year ended December 31, 2013 and related included in its registration statement on Form 10, which the SEC declared effective on June 10, 2014.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	'
	Note 2 - Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)”, which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets. This ASU will supersede the revenue recognition requirements in Topic 605, “Revenue Recognition”, and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, “Revenue Recognition-Construction-Type and Production-Type Contracts.” The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies will need to use more judgment and make more estimates than under today’s guidance. These may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard will be effective for TimkenSteel in the first quarter of fiscal year 2017. Early adoption is not permitted. TimkenSteel is currently evaluating the impact of the adoption of this accounting standard update on its results of operations and financial condition.
	In April 2014, the FASB issued ASU 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360).” ASU 2014-08 amends the requirements for reporting discontinued operations and requires additional disclosures about discontinued operations. Under the new guidance, only disposals representing a strategic shift in operations or that have a major effect on TimkenSteel’s operations and financial results should be presented as discontinued operations. ASU 2014-08 also requires expanded disclosures about discontinued operations, including information about the assets, liabilities, income, and expenses of discontinued operations. This new accounting guidance is effective for annual periods beginning after December 15, 2014. The adoption of ASU 2014-08 did not affect TimkenSteel’s Unaudited Consolidated Financial Statements because TimkenSteel did not have any discontinued operations.
	In July 2013, the FASB issued ASU 2013-11, Income Taxes (Topic 740): “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists.” ASU 2013-11 clarifies guidance and eliminates diversity in practice on the presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The new accounting rules were effective for annual and interim reporting periods beginning after December 15, 2013. Effective January 1, 2014, TimkenSteel adopted ASU 2013-11. The new accounting rules had no material impact on the results of operations and financial condition of TimkenSteel.

Inventory Disclosure [Text Block]	'
	Note 3 - Inventories
	The components of inventories, net as of June 30, 2014 and December 31, 2013 were as follows:
		June 30,			December 31,
		2014			2013
	Inventories, net:
	Manufacturing supplies		$34.10			$32.80
	Raw materials	45.8			42.9
	Work in process	89			81.6
	Finished products	72.6			71.6
	Subtotal	241.5			228.9
	Allowance for surplus and obsolete inventory	(2.7		)	(1.9		)
	Total Inventories, net		$238.80			$227.00
	Inventories are valued at the lower of cost or market, with approximately 65% valued by the last-in, first-out (LIFO) method and the remaining 35% valued by the first-in, first-out (FIFO) method. The majority of TimkenSteel’s domestic inventories are valued by the LIFO method. All of TimkenSteel’s manufacturing supplies inventory as well as its international (outside the United States) inventories are valued by the FIFO method.
	An actual valuation of the inventory under the LIFO method can be made only at the end of each year based on the inventory levels and costs at that time. Accordingly, interim LIFO calculations must be based on management’s estimates of expected year-end inventory levels and costs. Because these calculations are subject to many factors beyond management’s control, annual results may differ from interim results as they are subject to the final year-end LIFO inventory valuation.
	The LIFO reserve, excluding the impact of full-cost inventory adjustments, at June 30, 2014 and December 31, 2013 was $82.6 million and $75.5 million, respectively. TimkenSteel expects to recognize additional LIFO expense of approximately $7 million in the second half of 2014. The expected increase in the LIFO reserve for the year ended December 31, 2014 reflects higher anticipated costs, particularly scrap steel costs. A 1.0% increase in costs would increase the current LIFO expense estimate for the year ended December 31, 2014 by approximately $2 million. A 1.0% increase in inventory quantities would have no effect on the current LIFO expense estimate for 2014.

	Credit Facility
	On June 30, 2014, TimkenSteel entered into a credit facility with JPMorgan Chase Bank, N.A., as administrative agent, PNC Bank, National Association, as Syndication Agent, Bank of America, N.A. and HSBC Bank USA, National Association as Co-Documentation Agents and the other lenders and arrangers party thereto. The credit facility has a term of five years through June 30, 2019 and provides for a committed revolving credit line of up to $300.0 million. The credit facility includes an expansion option allowing TimkenSteel to request additional commitments of up to $150.0 million, in term loans or revolving credit commitments, subject to certain conditions and approvals as set forth in the credit agreement. The credit agreement provides a $50.0 million sublimit for multicurrency loans, a $50.0 million sublimit for letters of credit and a $30.0 million sublimit for swing line loans.
	The credit facility may be used for working capital and asset renewal and acquisition and is secured by a first priority lien on substantially all of the assets of TimkenSteel and its subsidiaries.
	TimkenSteel is required to maintain a certain capitalization ratio and interest coverage ratio as well as minimum liquidity balances as set forth in the credit agreement. As of June 30, 2014, TimkenSteel was in compliance with these ratios and liquidity requirements, as well as the additional covenants contained in the credit agreement. The credit agreement also provides the lenders with the ability to reduce the credit line amount, even if TimkenSteel is in compliance with all conditions of the credit agreement, upon a material adverse change to the business, properties, assets, financial condition or results of operations of TimkenSteel. The credit agreement contains a number of restrictions that limit TimkenSteel’s ability, among other things, and subject to certain limited exceptions, to incur additional indebtedness, pledge its assets as security, guaranty obligations of third parties, make investments, undergo a merger or consolidation, dispose of assets, or materially change its line of business. In addition, the credit agreement includes a cross-default provision whereby an event of default under other debt obligations, as defined in the credit agreement, will be considered an event of default under the credit agreement.
	Borrowings under the credit facility bear interest based on the daily balance outstanding at LIBOR (with no rate floor), plus an applicable margin (varying from 1.25% to 2.25%) or, in certain cases, an alternate base rate (based on a certain lending institution’s Prime Rate or as otherwise specified in the credit agreement, with no rate floor), plus an applicable margin (varying from 0.25% to 1.25%). The credit facility also carries a commitment fee equal to the unused borrowings multiplied by an applicable margin (varying from 0.20% to 0.40%). The applicable margins are calculated quarterly and vary based on TimkenSteel’s consolidated capitalization ratio as set forth in the credit agreement. On June 30, 2014, TimkenSteel borrowed $100.0 million under the revolving credit facility to pay a $50.0 million dividend to Timken, with the remaining amounts available to fund TimkenSteel’s operations. The interest rate under the revolving credit facility was 1.75% as of June 30, 2014. The amount available under the credit facility as of June 30, 2014 was $200.0 million.
	Revenue Refunding Bonds
	On June 1, 2014, Timken purchased in lieu of redemption the State of Ohio Water Development Revenue Refunding Bonds (Water Bonds), State of Ohio Air Quality Development Revenue Refunding Bonds (Air Quality Bonds) and State of Ohio Pollution Control Revenue Refunding Bonds (Pollution Control Bonds) (collectively, the Bonds). Pursuant to an Assignment and Assumption Agreement dated June 24, 2014 (the Assignment) between Timken and TimkenSteel, Timken assigned all of its right, title and interest in and to the loan agreement and the note, and these obligations were assumed by TimkenSteel. Additionally, replacement letters of credit were issued for the Water Bonds and the Pollution Control Bonds. The Bonds were remarketed on June 24, 2014 (the Remarketing Date) in connection with the conversion of the interest rate mode for the Bonds to the weekly rate and the delivery of the replacement letters of credit, as applicable. TimkenSteel is responsible for payment of the interest and principal associated with the Bonds subsequent to the Remarketing Date. As a result of the purchase and remarketing of the Bonds, TimkenSteel recorded a loss on debt extinguishment of $0.7 million during the second quarter of 2014 related to the write-off of original deferred financing costs, which are reflected as interest expense in the Unaudited Consolidated Statements of Income.
	All of TimkenSteel’s long-term debt is variable-rate debt, and, as a result, the carrying value of this debt is a reasonable estimate of fair value as interest rates on these borrowings approximate current market rates, which is considered a Level 2 input.

The amounts recorded related to the transfer to TimkenSteel plans were remeasured as of the date of transfer, which included updated valuation assumptions, as appropriate, and are expected to be adjusted in the third quarter of 2014 based on final actuarial analyses.
	Pension benefits earned are generally based on years of service and compensation during active employment. TimkenSteel’s funding policy is consistent with the funding requirements of applicable laws and regulations. Asset allocations are established in a manner consistent with projected plan liabilities, benefit payments and expected rates of return for the various asset classes. The expected rate of return for the investment portfolio is based on expected rates of return for various asset classes, as well as historical asset class and fund performance.
	Postretirement Benefits
	Prior to the spinoff, eligible retirees of TimkenSteel and their dependents were provided health care and life insurance benefits from the following Timken-sponsored plans: The Timken Company Bargaining Unit Welfare Benefit Plan for Retirees and The Timken Company Welfare Plan for Retirees. During the second quarter of 2014, the assets and liabilities of these postretirement plans related to TimkenSteel employees and retirees were transferred to postretirement plans sponsored by TimkenSteel. Plan assets of $130.1 million, benefit plan obligations of $232.2 million and accumulated other comprehensive losses of $7.9 million ($5.0 million, net of tax) were recorded by TimkenSteel related to these plans. The amounts recorded related to the transfer to TimkenSteel plans were remeasured as of the date of transfer, which included updated valuation assumptions, as appropriate, and are expected to be adjusted in the third quarter of 2014 based on final actuarial analyses.

	Net actuarial loss (gain)		$0.40				$—
	Prior service cost (credit)	13.9				0.4

	The weighted-average assumptions used in determining benefit obligations at each plan’s measurement date were as follows:
	Assumptions:	Pension			Postretirement
	Discount rate	4.65	%		4.33	%
	Future compensation assumption	3.11	%		n/a
	Expected long-term return on plan assets	7.25	%		5	%
	The discount rate assumption is based on current rates of high-quality long-term corporate bonds over the same period that benefit payments will be required to be made. The expected rate of return on plan assets assumption is based on the weighted-average expected return on the various asset classes in the plans’ portfolio. The asset class return is developed using historical asset return performance as well as current market conditions such as inflation, interest rates and equity market performance. For measurement purposes, the Company assumed a weighted-average annual rate of increase in the per capita cost (health care cost trend rate) of 7.25% for 2014, declining gradually to 5.00% in 2023 and thereafter for medical and prescription drug benefits, and 9.25% for 2014, declining gradually to 5.00% in 2023 and thereafter for HMO benefits.
	The components of net periodic benefit cost for the three and six months ended June 30, 2014 and 2013 were as follows:

As disclosed above, prior to the spinoff, employees of TimkenSteel participated in various retirement and postretirement benefits sponsored by Timken. Because Timken provided these benefits to eligible employees and retirees of TimkenSteel, the costs to participating employees of TimkenSteel in these plans were reflected in the Unaudited Consolidated Financial Statements, while the related assets and liabilities were retained by Timken. Expense allocations for these benefits were determined based on a review of personnel by business unit and based on allocations of corporate and other shared functional personnel. All cost allocations related to the various retirement benefit plans have been deemed paid by TimkenSteel to Timken in the period in which the cost was recorded in the Unaudited Consolidated Statements of Income as a component of cost of products sold and selling, general and administrative expenses. Allocated benefit cost from Timken were funded through intercompany transactions, which were reflected within the Net Parent Investment on the Unaudited Consolidated Balance Sheets.
TimkenSteel recognizes its overall responsibility to ensure that the assets of its various defined benefit pension plans are managed effectively and prudently and in compliance with its policy guidelines and all applicable laws. Preservation of capital is important; however, TimkenSteel also recognizes that appropriate levels of risk are necessary to allow its investment managers to achieve satisfactory long-term results consistent with the objectives and the fiduciary character of the pension funds. Asset allocations are established in a manner consistent with projected plan liabilities, benefit payments and expected rates of return for various asset classes. The expected rate of return for the investment portfolios is based on expected rates of return for various asset classes, as well as historical asset class and fund performance. The target allocations for plan assets are 27 percent equity securities, 51 percent debt securities and 22 percent in all other types of investments.
Fair value is defined 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 (exit price). The FASB provides accounting rules that classify the inputs used to measure fair value into the following hierarchy:
Level 1 -	Unadjusted quoted prices in active markets for identical assets or liabilities.
Level 2 -	Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability.
Level 3 -	Unobservable inputs for the asset or liability.
The following table presents the fair value hierarchy for those investments of TimkenSteel’s pension assets measured at fair value on a recurring basis as of June 30, 2014:

	Note 10 - Earnings Per Share
	On June 30, 2014, 45.4 million TimkenSteel common shares were distributed to Timken shareholders in conjunction with the spinoff. For comparative purposes, and to provide a more meaningful calculation for weighted average shares, this amount was assumed to be outstanding as of the beginning of each period presented in the calculation of basic weighted average shares. In addition, for the dilutive weighted average share calculations, the dilutive securities outstanding at June 30, 2014 were assumed to be also outstanding at each of the periods presented. Excluded from the diluted share calculation are 0.2 million shares related to stock options as their effect would have been anti-dilutive.
	The following table sets forth the reconciliation of the numerator and the denominator of basic earnings per share and diluted earnings per share for the three and six months ended June 30, 2014 and 2013:

Stock Based Compensation [Abstract]	'
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	'
	Note 11 - Stock-Based Compensation
	Description of the Plan
	Prior to the spinoff, employees of TimkenSteel were eligible to participate in The Timken Company Long-Term Incentive Plan (Timken LTIP Plan) and The Timken Company 2011 Long-Term Incentive Plan (Timken 2011 Plan) and received options to purchase Timken common shares. Effective June 30, 2014, TimkenSteel employees are eligible to participate in the TimkenSteel Corporation 2014 Equity and Incentive Compensation Plan (TimkenSteel 2014 Plan).
	The TimkenSteel 2014 Plan authorizes the Compensation Committee of the TimkenSteel Board of Directors to grant non-qualified or incentive stock options, stock appreciation rights, stock awards (including restricted stock and restricted stock unit awards), cash awards, and performance awards to TimkenSteel employees and non-employee directors. No more than 6.75 million TimkenSteel common shares may be delivered under the TimkenSteel 2014 Plan and no more than approximately 2.7 million common shares can be issued in settlement of restricted stock units awards from the 6.75 million common shares initially authorized. The TimkenSteel 2014 Plan authorizes the grant of up to 3.0 million “replacement awards” to current holders of Timken equity awards under Timken’s equity compensation plans.
	In connection with the spinoff, stock compensation awards granted under the Timken LTIP Plan and the Timken 2011 Plan were adjusted or substituted as follows:
	•	Vested and unvested stock options were adjusted and substituted so that the grantee holds options to purchase both Timken and TimkenSteel common shares.
	•	The adjustment to the Timken and TimkenSteel stock options, when combined, were intended to generally preserve the intrinsic value of each original option grant and the ratio of the exercise price to the fair market value of Timken common shares on June 30, 2014.
	•	Unvested restricted stock awards were replaced with adjusted, substitute awards for restricted shares or units, as applicable, of Timken and TimkenSteel common shares. The new awards of restricted stock were intended to generally preserve the intrinsic value of the original award determined as of June 30, 2014.
	•	Vesting periods of awards were unaffected by the adjustment and substitution.
	Awards granted in connection with the adjustment and substitution of awards originally issued under the Timken LTIP Plan and the Timken 2011 Plan are a part of the TimkenSteel 2014 Plan and reduce the maximum number of TimkenSteel common shares available for delivery under the TimkenSteel 2014 Plan. TimkenSteel will record compensation expense for both TimkenSteel and Timken common shares for awards held by TimkenSteel employees only.
	Outstanding Awards
	Awards outstanding under the TimkenSteel 2014 Plan as a result of the adjustment and substitution of the Timken LTIP Plan and the Timken 2011 Plan awards were as follows:
		Stock Options			Restricted Shares
		Number of Shares	Weighted Average Exercise Price		Number of Shares	Weighted Average Grant Date Fair Value
	Outstanding as of June 30, 2014*	1,859,312		$26.31	342,080		$31.94
	* Stock options and restricted shares presented in this table represent TimkenSteel awards only, including those held by Timken employees.
	The adjustment and substitution of the stock compensation awards occurred in conjunction with the distribution of TimkenSteel common shares to Timken shareholders in the June 30, 2014 after-market distribution. As a result, no grant, exercise, or cancellation activity occurred on TimkenSteel stock compensation awards during the six months ended June 30, 2014. Outstanding restricted shares include restricted shares, deferred shares, strategic performance shares and strategic shares that will settle in common shares. Strategic performance shares are performance-based restricted stock units that vest based on achievement of specified performance objectives and cliff-vest after three years. Strategic shares are timed-based restricted stock units and generally vest in 25% increments annually beginning on the first anniversary of the date of grant.
	As of June 30, 2014, unrecognized compensation cost related to stock option awards was $8.0 million, which is expected to be recognized over a weighted average period of 2.0 years. Unrecognized compensation cost related to restricted stock awards was $7.2 million, which is expected to be recognized over a weighted average period of 2.6 years. The calculations of unamortized expense and weighted-average periods include awards based on both TimkenSteel and Timken stock awards held by TimkenSteel employees.
	Certain strategic performance shares and performance-based restricted stock are settled in cash and were adjusted and substituted as described above. TimkenSteel accrued $4.0 million as of June 30, 2014, which was included in Salaries, wages and benefits, and Other non-current liabilities on the Unaudited Consolidated Balance Sheets. Compensation expense related to cash-settled awards was $2.0 million for the six months ended June 30, 2014, which includes $0.2 million of incremental compensation expense resulting from the adjustment and substitution on the distribution date.
	TimkenSteel recognized stock-based compensation expense of $2.4 million related to stock option awards and restricted shares for the six months ended June 30, 2014, which includes the recognition of $0.3 million of incremental compensation expense in the second quarter of 2014 resulting from the adjustment and substitution of stock-based awards.

	TimkenSteel operates and reports financial results for two segments: Industrial & Mobile and Energy & Distribution. These segments represent the level at which the chief operating decision maker (CODM) reviews the financial performance of TimkenSteel and makes operating decisions. Segment earnings before interest and taxes (EBIT) is the measure of profit and loss that the CODM uses to evaluate the financial performance of TimkenSteel and is the basis for resource allocation, performance reviews and compensation. For these reasons, TimkenSteel believes that Segment EBIT represents the most relevant measure of segment profit and loss. The CODM may exclude certain charges or gains, such as corporate charges and other special charges, from EBIT to arrive at a Segment EBIT that is a more meaningful measure of profit and loss upon which to base operating decisions. TimkenSteel defines Segment EBIT margin as Segment EBIT as a percentage of net sales.

	Historically, TimkenSteel has been managed and operated in the normal course of business with other affiliates of Timken. Transactions between Timken and TimkenSteel, with the exception of sales and purchase transactions and reimbursements for payments made to third-party service providers by Timken on TimkenSteel’s behalf, are reflected in equity in the Unaudited Consolidated Balance Sheets as Net Parent Investment and in the Unaudited Consolidated Statements of Cash Flows as a financing activity in Net transfers (to)/from Parent and affiliates.
	Corporate Costs/Allocations
	For the periods prior to April 1, 2014, the Unaudited Consolidated Financial Statements include corporate costs incurred by Timken for services that were provided to or on behalf of TimkenSteel, including but not limited to legal, treasury, corporate administration, technology and human resource services. These costs consist of allocated cost pools and direct costs. Corporate costs have been directly charged to, or allocated to, TimkenSteel using methods management believes are consistent and reasonable. TimkenSteel direct costs are incurred directly by TimkenSteel based on negotiated usage rates and dedicated employee assignments. These corporate charges and allocations have been deemed paid by TimkenSteel to Timken in the period in which the cost was recorded in the Unaudited Consolidated Statements of Income. Net charges from Timken for these services, reflected in selling, general and administrative expenses, were $7.4 million and $11.2 million for the six months ended June 30, 2014 and 2013, respectively. Effective April 1, 2014, TimkenSteel performed these functions using internal resources or services provided by third parties, certain of which were provided by Timken and directly charged to TimkenSteel for services provided. Timken will continue to provide such services during a transition period pursuant to a transition services agreement described below.
	Transactions with Other Timken Businesses
	Throughout the periods covered by the Unaudited Consolidated Financial Statements, TimkenSteel sold finished goods to Timken and its businesses. During the second quarter of 2014 and 2013, revenues from sales of products to Timken totaled $23.4 million, or 5.3% of net sales, and $18.8 million, or 5.3% of net sales, respectively. During the first six months of 2014 and 2013, revenues from related party sales of products totaled $46.0 million, or 5.5% of net sales, and $38.4 million, or 5.5% of net sales, respectively. Prior to the spinoff, TimkenSteel recorded related-party receivables from other Timken businesses as Accounts receivable due from related party in its Unaudited Consolidated Balance Sheets. Upon separation, outstanding amounts were reclassified to trade receivables.
	TimkenSteel purchased material from a related party for approximately $0.4 million and $1.3 million during the second quarter of 2014 and 2013, respectively. TimkenSteel purchased material from a related party for approximately $1.0 million and $2.7 million during the first six months of 2014 and 2013, respectively. In addition, certain of TimkenSteel’s third-party service providers are paid by Timken on behalf of TimkenSteel. TimkenSteel subsequently reimburses Timken in cash for such payments. Prior to the spinoff, TimkenSteel recorded related-party payables to other Timken businesses as Accounts payable due to related party in its Unaudited Consolidated Balance Sheets. Upon separation, outstanding amounts were reclassified to trade payables.
	Material Agreements Between TimkenSteel and Timken
	On June 30, 2014, TimkenSteel entered into a separation and distribution agreement and several other agreements with Timken to effect the spinoff and to provide a framework for the relationship with Timken. These agreements govern the relationship between TimkenSteel and Timken subsequent to the completion of the spinoff and provide for the allocation between TimkenSteel and Timken of assets, liabilities and obligations attributable to periods prior to the spinoff. Because these agreements were entered into in the context of a related party transaction, the terms may not be comparable to terms that would be obtained in a transaction between unaffiliated parties.
	Separation and Distribution Agreement — The separation and distribution agreement contains the key provisions relating to the spinoff, including provisions relating to the principal intercompany transactions required to effect the spinoff, the conditions to the spinoff and provisions governing the relationships between TimkenSteel and Timken after the spinoff.
	Tax Sharing Agreement — The tax sharing agreement, which generally governs TimkenSteel’s and Timken’s respective rights, responsibilities and obligations after the distribution with respect to taxes for any tax period ending on or before the distribution date, as well as tax periods beginning before and ending after the distribution date. Generally, TimkenSteel is liable for all pre-distribution U.S. federal income taxes, foreign income taxes and non-income taxes attributable to TimkenSteel’s business, and all other taxes attributable to TimkenSteel, paid after the distribution. In addition, the tax sharing agreement addresses the allocation of liability for taxes that are incurred as a result of restructuring activities undertaken to effectuate the distribution. The tax sharing agreement also provides that TimkenSteel is liable for taxes incurred by Timken that arise as a result of TimkenSteel’s taking or failing to take, as the case may be, certain actions that result in the distribution failing to meet the requirements of a tax-free distribution under Section 355 of the Internal Revenue Code of 1986, as amended.
	Employee Matters Agreement — TimkenSteel entered into an employee matters agreement with Timken, which generally provides that each of TimkenSteel and Timken has responsibility for its own employees and compensation plans, subject to certain exceptions as described in the agreement. In general, prior to the spinoff, TimkenSteel employees participated in various retirement, health and welfare, and other employee benefit and compensation plans maintained by Timken. Following the spinoff (or earlier, in the case of the tax-qualified defined benefit plans and retiree medical plans), pursuant to the employee matters agreement, TimkenSteel employees and former employees generally participate in similar plans and arrangements established and maintained by TimkenSteel. The employee matters agreement provides for the bifurcation of equity awards as described above. Among other things, the employee matters agreement also provides for TimkenSteel’s assumption of certain employment-related contracts that its employees originally entered into with Timken, the allocation of certain employee liabilities and the cooperation between TimkenSteel and Timken in the sharing of employee information.
	Transition Services Agreement — The transition services agreement governs the process under which TimkenSteel and Timken provides and/or makes available various administrative services and assets to each other, during what is expected to be a period of 24 months or less beginning on the distribution date. Services to be provided by Timken to TimkenSteel include certain services related to engineering, finance, facilities, information technology and employee benefits. Services to be provided by TimkenSteel to Timken include certain services related to engineering, operations, finance, facilities and information technology.
