Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets Disclosure [Text Block]	The Company tests goodwill and indefinite-lived intangible assets for impairment at least annually. The Company performs its annual impairment test as of October 1 after the annual forecasting process is completed. Furthermore, goodwill and indefinite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The Company reviews goodwill for impairment at the reporting unit level. The Mobile Industries segment has three reporting units and the Process Industries segment has two reporting units. Changes in the carrying value of goodwill were as follows: Year ended December 31, 2015 : Mobile Industries Process Industries Total Beginning Balance $ 89.6 $ 169.9 $ 259.5 Acquisitions 8.2 62.6 70.8 Other (0.8 ) (2.2 ) (3.0 ) Ending Balance $ 97.0 $ 230.3 $ 327.3 Acquisitions in 2015 related to the preliminary purchase price allocation for the Belts business completed on September 1, 2015. $59.7 million of the goodwill acquired for the Belts business is tax-deductible and will be recognized over 15 years for tax purposes. The remaining $11.1 million is non-deductible for tax purposes. “Other” primarily includes foreign currency translation adjustments. Year ended December 31, 2014 : Mobile Industries Process Industries Total Beginning Balance $ 176.7 $ 169.4 $ 346.1 Acquisitions — 3.3 3.3 Impairment (86.3 ) — (86.3 ) Other (0.8 ) (2.8 ) (3.6 ) Ending Balance $ 89.6 $ 169.9 $ 259.5 The change related to acquisitions reflects the results of preliminary purchase price allocations for the acquisitions of Schulz on April 28, 2014 and Revolvo on November 30, 2014. The goodwill acquired from Schulz of $2.9 million is tax-deductible and will be amortized over 15 years . The goodwill acquired from Revolvo of $0.4 million is tax-deductible and is estimated to be amortized over approximately 15 years . These amounts were updated in 2015. “Other” primarily included foreign currency translation adjustments for 2014 . Refer to Note 3 - Acquisitions and Divestitures for additional information on the acquisitions listed above. During the third quarter of 2014, the Company reviewed goodwill for impairment for two of its reporting units within the Company's former Aerospace segment (now included in the Mobile Industries segment) as a result of declining sales forecasts and financial performance within the segment. The Company utilizes both an income approach and a market approach in testing goodwill for impairment. The Company utilized updated forecasts for the income approach as part of the goodwill impairment review. As a result of the lower earnings and cash flow forecasts, the Company determined that the Aerospace Transmissions and the Aerospace Aftermarket reporting units could not support the carrying value of their goodwill. As a result, the Company recorded a pretax impairment loss of $86.3 million during the third quarter of 2014, which was reported in impairment and restructuring charges in the Consolidated Statement of Income. In 2015 and 2013 , no goodwill impairment losses were recorded.

Most of these lines of credit are uncommitted. At December 31, 2015 , the Company’s foreign subsidiaries had borrowings outstanding of $13.0 million and guarantees of $4.4 million , which reduced the availability under these facilities to $200.5 million . The weighted-average interest rate on short-term debt during the year was 1.1% , 3.1% and 3.2% in 2015 , 2014 and 2013 , respectively. The weighted-average interest rate on short-term debt outstanding at December 31, 2015 and 2014 was 0.90% and 1.39% , respectively. The decrease in the weighted-average interest rate was primarily due to increased borrowings in the U.S. at a lower rate. The Company has a $100 million Accounts Receivable Facility that matures on November 30, 2018 . Under the terms of the Accounts Receivable Facility, the Company sells, on an ongoing basis, certain domestic trade receivables to Timken Receivables Corporation, a wholly-owned consolidated subsidiary that in turn uses the trade receivables to secure borrowings which are funded through a vehicle that issues commercial paper in the short-term market. Borrowings under the Accounts Receivable Facility are limited to certain borrowing base calculations. Any amounts outstanding under this Accounts Receivable Facility would be reported in short-term debt on the Company's Consolidated Balance Sheets. Certain borrowing base limitations reduced the availability of the Accounts Receivable Facility to $54.6 million at December 31, 2015 . As of December 31, 2015 , there were outstanding borrowings of $49.0 million under the Accounts Receivable Facility, which reduced the availability under this facility to $5.6 million . As of December 31, 2014 , there were no outstanding borrowings under the Accounts Receivable Facility. The cost of this facility, which is the commercial paper rate plus program fees, is considered a financing cost and is included in interest expense in the Consolidated Statements of Income. The yield rate was 1.05% , 0.20% and 0.96% , at December 31, 2015 , 2014 and 2013 , respectively.

At December 31, 2015 , the Company had $75.2 million of outstanding borrowings under the Senior Credit Facility, which reduced the availability under this facility to $424.8 million . Under the Senior Credit Facility, the Company has two financial covenants: a consolidated leverage ratio and a consolidated interest coverage ratio. At December 31, 2015 , the Company was in full compliance with the covenants under the Senior Credit Facility. On August 20, 2014, the Company issued the 2024 Notes. The Company used the net proceeds from the issuance of the 2024 Notes to repay the Company's 2014 Notes and for general corporate purposes. The maturities of long-term debt for the five years subsequent to December 31, 2015 are as follows: 2016 – $15.1 million ; 2017 – $5.0 million ; 2018 – zero ; 2019 – zero and 2020 - $75.2 million . Interest paid was $32.1 million in 2015 , $34.4 million in 2014 and $31.0 million in 2013 . This differs from interest expense due to the timing of payments and interest capitalized of zero in 2015 , $1.6 million in 2014 and $12.7 million in 2013 . The Company and its subsidiaries lease a variety of real property and equipment. Rent expense under operating leases amounted to $33.5 million , $33.0 million and $35.6 million in 2015 , 2014 and 2013 , respectively. At December 31, 2015 , future minimum lease payments for noncancelable operating leases totaled $142.2 million and are payable as follows: 2016 - $35.1 million ; 2017 - $29.4 million ; 2018 - $24.4 million ; 2019 - $20.8 million ; 2020 - $18.5 million and $14.0 million thereafter.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	The Company and certain of its subsidiaries have been identified as potentially responsible parties for investigation and remediation under the Superfund or similar state laws with respect to certain sites. Claims for investigation and remediation have been asserted against numerous other entities, which are believed to be financially solvent and are expected to fulfill their proportionate share of the obligation. The Company had an accrual of $1.2 million and $1.5 million for environmental matters that are probable and reasonably estimable as of December 31, 2015 and 2014 , respectively. This accrual was recorded based upon the best estimate of costs to be incurred in light of the progress made in determining the magnitude of remediation costs, the timing and extent of remedial actions required by governmental authorities and the amount of the Company’s liability in proportion to other responsible parties. Of the 2015 and 2014 accruals, $0.3 million and $0.6 million , respectively, was included in the rollforward of the restructuring accrual as of December 31, 2015 , discussed further in Note 12 - Impairment and Restructuring Charges . In addition, the Company is subject to various lawsuits, claims and proceedings, which arise in the ordinary course of its business. The Company accrues costs associated with legal and non-income tax matters when they become probable and reasonably estimable. Accruals are established based on the estimated undiscounted cash flows to settle the obligations and are not reduced by any potential recoveries from insurance or other indemnification claims. Management believes that any ultimate liability with respect to these actions, in excess of amounts provided, will not materially affect the Company’s Consolidated Financial Statements. In October 2014, the Brazilian government antitrust agency announced that it had opened an investigation of alleged antitrust violations in the bearing industry. The Company’s Brazilian subsidiary, Timken do Brasil Comercial Importadora Ltda, was included in the investigation. While the Company is unable to predict the ultimate length, scope or results of the investigation, management believes that the outcome will not have a material effect on the Company’s consolidated financial position; however, any such outcome may be material to the results of operations of any particular period in which costs, if any, are recognized. Based on current facts and circumstances, the low end of the range for potential penalties, if any, would be immaterial to the Company. Product Warranties: In addition to the contingencies above, the Company provides limited warranties on certain of its products. The following is a rollforward of the warranty liability for 2015 and 2014 : 2015 2014 Beginning balance, January 1 $ 1.7 $ 4.2 Expense (Income) 0.6 (1.4 ) Payments (1.3 ) (1.1 ) Ending balance, December 31 $ 1.0 $ 1.7 The product warranty liability for 2015 and 2014 was included in other current liabilities on the Consolidated Balance Sheets.

Coughlin, Executive Vice President and Group President; (2) sold the assets of its aerospace engine overhaul business, located in Mesa, Arizona, during the fourth quarter of 2014; (3) evaluated strategic alternatives for its aerospace MRO parts business, also located in Mesa; and (4) announced plans to close its aerospace bearing facility located in Wolverhampton, U.K. by early 2016, rationalizing the capacity into existing facilities. In conjunction with this announcement, the Company reviewed goodwill for impairment for its three reporting units within the Aerospace segment as a result of declining sales forecasts and financial performance within the segment. As a result of that review, the Company recorded a pretax goodwill impairment charge of $86.3 million during the third quarter of 2014 related to its Aerospace Transmissions and Aerospace Aftermarket reporting units. In addition, the Company recorded an intangible asset impairment charge of $9.9 million , an impairment charge of $1.2 million for its engine overhaul business, which it classified as assets held for sale and severance and related benefits of $0.3 million . During the fourth quarter of 2014, the Company recorded severance and related benefits of $3.7 million related to the planned closure of Wolverhampton. See Note 18 - Fair Value for additional information on the impairment charges for the former Aerospace segment. In May 2012, the Company announced the closure of its manufacturing facility in St. Thomas, which was expected to be completed in approximately one year , and was intended to consolidate bearing production from this plant with existing U.S. operations to better align the Company's manufacturing footprint and customer base. In connection with this closure, the Company also moved customer service for the Canadian market to its offices in Toronto. The Company completed the closure of this manufacturing facility on March 31, 2013. The closure of the St. Thomas manufacturing facility displaced 190 employees. The Company has incurred pretax costs related to this closure of approximately $41.8 million as of December 31, 2015 , including rationalization costs recorded in cost of products sold. During 2013, the Company recorded $1.1 million of severance and related benefits related to this closure. In March 2007 , the Company announced the closure of its manufacturing facility in Sao Paulo. The Company completed the closure of this manufacturing facility on March 31, 2010 . Mobile Industries has incurred cumulative pretax expenses of approximately $55.2 million as of December 31, 2015 related to this closure. In 2013 , the Company recorded a favorable adjustment of $2.0 million associated with the closure of this facility. The favorable adjustment for 2013 was primarily related to environmental remediation costs. In addition to the above charges, during 2015 and 2014, the Company recorded severance and related benefit costs of $1.2 million and $2.9 million related to the rationalization of one of its facilities in Europe. Process Industries During 2015, the Company recorded $2.9 million of exit costs related to the Company's termination of its relationship with one of its third-party sales representatives in Colombia. In addition, the Company recorded impairment charges of $3.0 million related to one of the Company's repair business in Niles, Ohio. See Note 18 - Fair Value for additional information on the impairment charges for the repair business. Workforce Reductions: In 2015 , the Company recognized $6.5 million of severance and related benefits to eliminate approximately 100 positions to improve efficiency and reduce costs. Of the $6.5 million charge for 2015, $3.4 million related to the Mobile Industries segment, $2.5 million related to the Process Industries segment and $0.6 million related to Corporate positions. During 2013, the Company recognized $5.9 million of severance and related benefit costs to eliminate approximately 180 positions. Of the $5.9 million charge for 2013, $3.4 million related to the Mobile Industries segment and $2.5 million related to the Process Industries segment.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock Compensation Plans	Under the Company’s long-term incentive plan, the Company’s common shares have been made available for grant, at the discretion of the Compensation Committee of the Board of Directors, to officers and key employees in the form of stock option awards. Stock option awards typically have a ten -year term and generally vest in 25% increments annually beginning on the first anniversary of the date of grant. In addition to stock option awards, the Company has granted restricted shares, deferred shares, performance-based restricted stock units and time-vested restricted stock units under the long-term incentive plan. During 2015 , 2014 and 2013 , the Company recognized stock-based compensation expense of $6.6 million ( $4.1 million after tax or $0.05 per diluted share), $13.7 million ( $8.5 million after tax or $0.09 per diluted share) and $12.1 million ( $7.6 million after tax or $0.08 per diluted share), respectively, for stock option awards. The fair value of stock option awards granted during 2015 , 2014 and 2013 was estimated at the date of grant using a Black-Scholes option-pricing method with the following assumptions: 2015 2014 2013 Weighted-average fair value per option (Pre-Spinoff for 2014 and 2013) $ 11.67 $ 23.09 $ 21.17 Risk-free interest rate 1.58 % 1.64 % 1.09 % Dividend yield 2.29 % 1.75 % 2.29 % Expected stock volatility 36.53 % 50.96 % 50.66 % Expected life - years 5 5 6 Historical information was the primary basis for the selection of the expected dividend yield, expected volatility and the expected lives of the options. The dividend yield was calculated based upon the last dividend prior to the grant compared to the trailing 12 months' daily stock prices. The risk-free interest rate was based upon yields of U.S. zero coupon issues with a term equal to the expected life of the option being valued. Forfeitures were estimated at 2.3% . A summary of stock option award activity for the year ended December 31, 2015 is presented below: Number of Shares Weighted-average Weighted-average Aggregate Intrinsic Value (millions) Outstanding - beginning of year 3,168,363 $ 33.57 Granted - new awards 491,615 41.56 Exercised (297,765 ) 22.35 Canceled or expired (82,345 ) 40.95 Outstanding - end of year 3,279,868 $ 35.60 6 years $ 5.9 Options expected to vest 3,257,113 $ 35.55 6 years $ 5.9 Options exercisable 2,034,395 $ 32.41 5 years $ 5.9 The total intrinsic value of stock option awards exercised during the years ended December 31, 2015 , 2014 and 2013 was $5.6 million , $21.5 million and $25.2 million , respectively. Net cash proceeds from the exercise of stock option awards were $4.1 million , $16.8 million and $13.1 million , respectively. Income tax benefits were $1.3 million , $5.9 million and $8.9 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. In 2015, the Company issued 288,585 performance-based restricted stock units and 211,980 time-vesting restricted stock units to officers and key employees. These performance-based restricted stock units vest based on achievement of specified performance objectives and cliff-vest after 3 years . These performance-based restricted stock units settle in either cash or shares, with 8,580 shares expected to settle in cash and 280,005 expected to settle in shares. Time-vesting restricted stock units vest in 25% increments annually beginning on the first anniversary of the grant or cliff-vest after five years . Time-vesting restricted stock units also settle in either cash or shares, with 6,010 time-vesting restricted stock units expected to settle in cash and 205,970 time-vesting restricted stock units expected to settle in common shares. For time-vesting restricted stock units that are expected to settle in cash, the Company had $6.1 million and $15.3 million , accrued in salaries, wages and benefits as of December 31, 2015 and 2014, respectively, on the Consolidated Balance Sheets. A summary of stock award activity, including restricted shares, deferred shares, performance-based restricted stock units and time-vested restricted stock units that will settle in common shares, for the year ended December 31, 2015 is as follows: Number of Shares Weighted-average Outstanding - beginning of year 687,030 $ 39.61 Granted - new awards 485,975 41.39 Vested (103,953 ) 36.37 Canceled or expired (54,282 ) 41.44 Outstanding - end of year 1,014,770 $ 40.69 As of December 31, 2015 , a total of 1,014,770 stock awards have been awarded that have not yet vested.

Retirement Benefit Plans

Retirement Benefit Plans	12 Months Ended

Pension Plan, Defined Benefit [Member]
Defined Benefit Plan Disclosure [Line Items]
Retirement Benefit Plans	The Company and its subsidiaries sponsor a number of defined benefit pension plans, which cover eligible employees, including certain employees in foreign countries. These plans are generally noncontributory. Pension benefits earned are generally based on years of service and compensation during active employment. The cash contributions for the Company’s defined benefit pension plans were $10.8 million , $21.1 million and $120.7 million in 2015 , 2014 and 2013, respectively. The following tables summarize the net periodic benefit cost information and the related assumptions used to measure the net periodic benefit cost for the years ended December 31: U.S. Plans International Plans 2015 2014 2013 2015 2014 2013 Components of net periodic benefit cost: Service cost $ 15.4 $ 21.5 $ 35.7 $ 2.2 $ 2.4 $ 2.8 Interest cost 45.6 98.3 116.2 12.3 17.7 18.5 Expected return on plan assets (62.6 ) (152.0 ) (207.6 ) (16.7 ) (23.7 ) (24.4 ) Amortization of prior service cost 2.8 3.5 4.5 0.1 0.1 — Amortization of net actuarial loss 31.1 55.6 109.2 5.2 5.3 7.6 Curtailment — — — 0.6 — — Settlement 456.4 32.7 — 4.8 0.8 7.2 Special termination benefits — — — 0.6 — — Less: Discontinued operations — (8.0 ) (24.2 ) — 0.4 0.4 Net periodic benefit cost $ 488.7 $ 51.6 $ 33.8 $ 9.1 $ 3.0 $ 12.1 Assumptions 2015 2014 2013 U.S. Plans: Discount rate 3.98% to 4.64% 4.68% / 5.02% 4.00 % Future compensation assumption 2.00% to 3.00% 2.00% to 3.00% 2.00% to 3.00% Expected long-term return on plan assets 6.00 % 7.25 % 8.00 % International Plans: Discount rate 1.50% to 8.75% 3.25% to 9.75% 2.75% to 9.00% Future compensation assumption 2.20% to 8.00% 2.30% to 8.00% 2.30% to 8.00% Expected long-term return on plan assets 2.25% to 9.25% 3.00% to 8.50% 3.25% to 8.50% In 2015, the Company entered into two agreements pursuant to which two of the Company's U.S. defined benefit pension plans purchased group annuity contracts from Prudential. The two group annuity contracts require Prudential to pay and administer future pension benefits for approximately 8,400 U.S. Timken retirees in the aggregate. The Company transferred a total of approximately $1.1 billion of its pension obligations and a total of approximately $1.2 billion of pension assets to Prudential in these transactions. In addition to the purchase of the group annuity contracts, the Company made lump-sum distributions of $37.2 million to new retirees in the U.S. The Company also entered into an agreement pursuant to which one of the Company's Canadian defined benefit pension plans purchased a group annuity contract from Canada Life. The group annuity contract requires Canada Life to pay and administer future pension benefits for approximately 40 Canadian retirees. As a result of the group annuity contracts, lump-sum distributions, as well as pension settlement and curtailment charges related to the Company's Canadian pension plans, the Company incurred total pension settlement and curtailment charges of $465.0 million , including professional fees of $2.6 million , in 2015. In 2014, the Company incurred pension settlement charges of $33.7 million , including professional fees, primarily to settle approximately $110 million of the Company's pension obligations related to one of its defined benefit pension plans in the U.S. as a result of the lump sum distributions for 2014 retirements and certain deferred vested plan participants. 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 expense purposes in 2015 , the Company applied a discount rate of 4.20% for one month of 2015 and a discount rate of 3.98% for eleven months for one of its U.S. defined benefit pension plans due to the remeasurement of the defined benefit pension plan as a result of the purchase of a group annuity contract in January 2015. For expense purposes in 2015 , the Company applied a discount rate of 4.20% for eleven months of 2015 and a discount rate of 4.64% for one month for another of its U.S. defined benefit pension plans as a result of a remeasurement of the defined benefit pension plan due to the purchase of a group annuity contract in November 2015. For expense purposes in 2016 , the Company will apply a discount rate of 4.69% to its U.S. defined benefit pension plans. For expense purposes in 2015 , the Company applied an expected rate of return of 6.00% for the Company’s U.S. pension plan assets. For expense purposes in 2016 , the Company will apply an expected rate of return on plan assets of 5.75% . The reduction in expected rate of return on plan assets was due to the Company's move to a greater investment in fixed-income debt securities offset by a reduction in equity securities in an effort to de-risk the assets and maintain its overfunded status on U.S. pension plans. The following tables set forth the change in benefit obligation, change in plan assets, funded status and amounts recognized on the Consolidated Balance Sheets for the defined benefit pension plans as of December 31, 2015 and 2014 : U.S. Plans International Plans 2015 2014 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ 1,703.9 $ 2,642.4 $ 415.7 $ 491.1 Service cost 15.4 21.5 2.2 2.4 Interest cost 45.6 98.3 12.3 17.7 Amendments — — — 0.3 Actuarial losses (gains) 68.8 239.6 (31.6 ) 38.7 Employee contributions — — — 0.3 International plan exchange rate change — — (29.5 ) (29.5 ) Curtailment — — 0.5 — Benefits paid (100.9 ) (234.6 ) (17.6 ) (23.5 ) Special termination benefits — — 0.6 — Settlements (1,162.8 ) — (14.5 ) — Acquisitions 19.9 — — — Spinoff of TimkenSteel — (1,063.3 ) — (81.8 ) Benefit obligation at end of year $ 589.9 $ 1,703.9 $ 338.1 $ 415.7 U.S. Plans International Plans 2015 2014 2015 2014 Change in plan assets: Fair value of plan assets at beginning of year $ 1,772.4 $ 2,870.0 $ 349.4 $ 420.6 Actual return on plan assets 23.0 250.5 4.5 42.2 Employee contributions — — — 0.3 Company contributions / payments 4.4 4.5 6.4 16.6 International plan exchange rate change — — (23.6 ) (21.2 ) Acquisitions 17.6 — — — Settlements (1,162.8 ) — (14.5 ) — Benefits paid (100.9 ) (234.6 ) (17.6 ) (23.5 ) Spinoff of TimkenSteel — (1,118.0 ) — (85.6 ) Fair value of plan assets at end of year 553.7 1,772.4 304.6 349.4 Funded status at end of year $ (36.2 ) $ 68.5 $ (33.5 ) $ (66.3 ) Amounts recognized on the Consolidated Balance Sheets: Non-current assets $ 69.0 $ 176.2 $ 17.3 $ — Current liabilities (4.2 ) (4.1 ) (4.9 ) (4.0 ) Non-current liabilities (101.0 ) (103.6 ) (45.9 ) (62.3 ) $ (36.2 ) $ 68.5 $ (33.5 ) $ (66.3 ) Amounts recognized in accumulated other comprehensive loss: Net actuarial loss $ 187.4 $ 566.5 $ 93.3 $ 132.3 Net prior service cost 9.1 11.9 0.5 0.7 Accumulated other comprehensive loss $ 196.5 $ 578.4 $ 93.8 $ 133.0 Changes in plan assets and benefit obligations recognized in accumulated other comprehensive loss (AOCL): AOCL at beginning of year $ 578.4 $ 865.4 $ 133.0 $ 142.7 Net actuarial loss (gain) 108.4 141.0 (18.9 ) 20.2 Prior service cost — — — 0.3 Recognized net actuarial loss (31.1 ) (55.6 ) (5.2 ) (5.3 ) Recognized prior service cost (2.8 ) (3.5 ) (0.1 ) (0.1 ) Loss recognized due to curtailment — — (0.6 ) — Loss recognized due to settlement (456.4 ) (32.7 ) (4.8 ) (0.8 ) Foreign currency impact — — (9.6 ) (9.8 ) TimkenSteel Spinoff — (336.2 ) — (14.2 ) Total recognized in accumulated other comprehensive loss at December 31 $ 196.5 $ 578.4 $ 93.8 $ 133.0 The presentation in the above tables for amounts recognized in accumulated other comprehensive loss on the Consolidated Balance Sheets is before the effect of income taxes. The following table summarizes assumptions used to measure the benefit obligation for the defined benefit pension plans at December 31: Assumptions 2015 2014 U.S. Plans: Discount rate 4.69 % 4.20 % Future compensation assumption 2.00% to 3.00% 2.00% to 3.00% International Plans: Discount rate 2.00% to 8.50% 1.50% to 8.75% Future compensation assumption 2.20% to 8.00% 2.20% to 8.00% Defined benefit pension plans in the United States represent 64% of the benefit obligation and 65% of the fair value of plan assets as of December 31, 2015 . Certain of the Company’s defined benefit pension plans were overfunded as of December 31, 2015 . As a result, $86.3 million and $176.2 million at December 31, 2015 and 2014 , respectively, are included in non-current pension assets on the Consolidated Balance Sheets. The current portion of accrued pension cost, which was included in salaries, wages and benefits on the Consolidated Balance Sheets, was $9.1 million and $8.1 million at December 31, 2015 and 2014 , respectively. In 2015 , the current portion of accrued pension cost relates to unfunded plans and represents the actuarial present value of expected payments related to the plans to be made over the next 12 months. The accumulated benefit obligation at December 31, 2015 exceeded the market value of plan assets for several of the Company’s pension plans. For these plans, the projected benefit obligation was $207.6 million , the accumulated benefit obligation was $196.8 million and the fair value of plan assets was $52.2 million at December 31, 2015 . The total pension accumulated benefit obligation for all plans was $0.9 billion and $2.1 billion at December 31, 2015 and 2014 , respectively. Investment performance increased the value of the Company’s pension assets by 0.6% . As of December 31, 2015 and 2014 , the Company’s defined benefit pension plans did not directly hold any of the Company’s common shares. The estimated net actuarial loss and prior service cost for the defined benefit pension plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost over the next fiscal year are $16.5 million and $1.7 million , respectively. Plan Assets: The Company’s target allocation for pension plan assets, as well as the actual pension plan asset allocations as of December 31, 2015 and 2014 , was as follows: Current Target Allocation Percentage of Pension Plan Assets at December 31, Asset Category 2015 2014 Equity securities 6% to 12% 15% 10% Debt securities 70% to 90% 63% 77% Other 7% to 15% 22% 13% Total 100% 100% The current asset allocation deviates from the target asset allocation due to the transfer of fixed income assets to Prudential in connection with the annuity purchase for one of the Company's US pension plans that was completed in November 2015. The Company intends to have the actual asset allocations in line with the target allocations by the conclusion of 2016. The Company 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, the Company 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 portfolio is based on expected rates of return for various asset classes, as well as historical asset class and fund performance. 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 the Company’s pension assets measured at fair value on a recurring basis as of December 31, 2015 : U.S. Pension Plans International Pension Plans Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 65.9 $ 23.9 $ 42.0 $ — $ 31.0 $ 12.8 $ 18.2 $ — Government and agency securities 35.1 32.9 2.2 — — — — — Corporate bonds - investment grade 56.0 — 56.0 — 3.0 — 3.0 — Equity securities - U.S. companies 9.8 9.7 0.1 — — — — — Equity securities - international companies 6.1 6.1 — — 0.9 — 0.9 — Common collective funds - domestic equities 13.0 — 13.0 — — — — — Common collective funds - international equities 14.2 — 14.2 — 81.4 — 81.4 — Common collective funds - fixed income 173.5 — 173.5 — 85.0 — 85.0 — Common collective funds - other — — — — 103.3 — 103.3 — Limited partnerships 52.8 — — 52.8 — — — — Real estate partnerships 99.7 — 71.9 27.8 — — — — Risk parity 27.6 — 27.6 — — — — — Total Assets $ 553.7 $ 72.6 $ 400.5 $ 80.6 $ 304.6 $ 12.8 $ 291.8 $ — The table below sets forth a summary of changes in the fair value of the level 3 assets by fund for the year ended December 31, 2015 : Limited Partnerships Real Estate Total Beginning balance, January 1 $ 66.1 $ 27.8 $ 93.9 Purchases 0.6 7.0 7.6 Sales (9.8 ) (8.3 ) (18.1 ) Realized losses (7.5 ) (4.7 ) (12.2 ) Unrealized gains 3.4 6.0 9.4 Ending balance, December 31 $ 52.8 $ 27.8 $ 80.6 The following table presents the fair value hierarchy for those investments of the Company’s pension assets measured at fair value on a recurring basis as of December 31, 2014 : U.S. Pension Plans International Pension Plans Total Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 55.3 $ 0.8 $ 54.5 $ — $ 25.5 $ — $ 25.5 $ — Government and agency securities 505.9 496.4 9.5 — — — — — Corporate bonds - investment grade 473.7 — 473.7 — 2.7 — 2.7 — Equity securities - U.S. companies 22.7 22.7 — — 30.2 30.2 — — Equity securities - international companies 16.3 16.3 — — 26.6 25.7 0.9 — Asset backed securities — — — — 3.4 — 3.4 — Common collective funds - domestic equities 22.6 — 22.6 — 2.1 — 2.1 — Common collective funds - international equities 27.4 — 27.4 — 60.6 — 60.6 — Common collective funds - fixed income 379.5 — 379.5 — 108.9 — 108.9 — Common collective funds - other — — — — 89.4 — 89.4 — Limited partnerships 66.1 — — 66.1 — — — — Real estate partnerships 112.6 — 84.8 27.8 — — — — Risk Parity 90.3 — 90.3 — — — — — Total Assets $ 1,772.4 $ 536.2 $ 1,142.3 $ 93.9 $ 349.4 $ 55.9 $ 293.5 $ — The table below sets forth a summary of changes in the fair value of the level 3 assets by fund for the year ended December 31, 2014 : Limited Partnerships Real Estate Total Beginning balance, January 1 $ 78.8 $ 21.1 $ 99.9 Purchases 2.1 10.5 12.6 Sales (16.8 ) (5.6 ) (22.4 ) Realized losses (11.0 ) (4.1 ) (15.1 ) Unrealized gains 13.0 5.9 18.9 Ending balance, December 31 $ 66.1 $ 27.8 $ 93.9 Cash and cash equivalents are valued at redemption value. Government and agency securities are valued at the closing price reported in the active market in which the individual securities are traded. Certain corporate bonds are valued at the closing price reported in the active market in which the bond is traded. Equity securities (both common and preferred stock) are valued at the closing price reported in the active market in which the individual security is traded. Common collective funds are valued based on a net asset value per share. Asset-backed securities are valued based on quoted prices for similar assets in active markets. When such prices are unavailable, the plan trustee determines a valuation from the market maker dealing in the particular security. Limited partnerships include investments in funds that invest primarily in private equity, venture capital and distressed debt. Limited partnerships are valued based on the ownership interest in the net asset value of the investment, which is used as a practical expedient to fair value, per the underlying investment fund, which is based upon the general partner's own assumptions about the assumptions a market participant would use in pricing the assets and liabilities of the partnership. Real estate investments include funds that invest in companies that primarily invest in commercial and residential properties, commercial mortgage-backed securities, debt and equity securities of real estate operating companies, and real estate investment trusts. Other real estate investments are valued based on the ownership interest in the net asset value of the investment, which is used as a practical expedient to fair value per the underlying investment fund, which is based on appraised values and current transaction prices. Risk parity investments include funds that invest in diversified global asset classes (equities, bonds, inflation-linked bonds, and commodities) with leverage to balance risk and achieve consistent returns with lower volatility. Risk parity investments are valued based on the closing prices of the underlying securities in the active markets in which they are traded. Cash Flows: Employer Contributions to Defined Benefit Plans 2014 $ 21.1 2015 10.8 2016 (planned) 15.0 Future benefit payments, including lump sum distributions, are expected to be as follows: Benefit Payments 2016 $ 94.5 2017 67.4 2018 59.5 2019 83.8 2020 63.2 2021-2025 331.6 Employee Savings Plans: The Company sponsors defined contribution retirement and savings plans covering substantially all employees in the United States and employees at certain non-U.S. locations. The Company has contributed its common shares to certain of these plans based on formulas established in the respective plan agreements. At December 31, 2015 , the plans held 4,116,090 of the Company’s common shares with a fair value of $117.7 million . Company contributions to the plans, including performance sharing, were $22.4 million in 2015 , $26.1 million in 2014 and $28.5 million in 2013 .

Defined Benefit Plan Disclosure [Line Items]
Postretirement Benefit Plans	The Company and its subsidiaries sponsor several funded and unfunded postretirement plans that provide health care and life insurance benefits for eligible retirees and dependents. Depending on retirement date and employee classification, certain health care plans contain contribution and cost-sharing features such as deductibles, coinsurance and limitations on employer-provided subsidies. The remaining health care and life insurance plans are noncontributory. The following tables summarize the net periodic benefit cost information and the related assumptions used to measure the net periodic benefit cost for the years ended December 31 : 2015 2014 2013 Components of net periodic benefit cost: Service cost $ 0.4 $ 1.3 $ 2.9 Interest cost 10.9 16.7 21.7 Expected return on plan assets (7.1 ) (8.5 ) (11.1 ) Amortization of prior service credit 0.8 1.0 (0.2 ) Amortization of net actuarial loss 0.1 — 2.3 Less: discontinued operations — (3.1 ) (6.4 ) Net periodic benefit cost $ 5.1 $ 7.4 $ 9.2 Assumptions: 2015 2014 2013 Discount rate 3.95 % 4.33% / 4.59% 3.80 % Rate of return 6.25 % 5.00 % 5.00 % 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 expense purposes in 2015 , the Company applied a discount rate of 3.95% to its postretirement benefit plans. For expense purposes in 2016 , the Company will apply a discount rate of 4.39% to its postretirement benefit plans. For expense purposes in 2015 , the Company applied an expected rate of return of 6.25% to the VEBA trust assets. For expense purposes in 2016, the Company will apply an expected rate of return of 6.00% to the VEBA trust assets. The following tables set forth the change in benefit obligation, change in plan assets, funded status and amounts recognized on the Consolidated Balance Sheets of the postretirement benefit plans as of December 31, 2015 and 2014 : 2015 2014 Change in benefit obligation: Benefit obligation at beginning of year $ 284.6 $ 515.6 Service cost 0.4 1.3 Interest cost 10.9 16.7 Actuarial (gains) losses (7.7 ) 18.0 International plan exchange rate change (0.3 ) (0.1 ) Benefits paid (26.3 ) (37.1 ) Spinoff of TimkenSteel — (229.8 ) Acquisition 1.1 — Benefit obligation at end of year $ 262.7 $ 284.6 2015 2014 Change in plan assets: Fair value of plan assets at beginning of year $ 120.7 $ 240.1 Company contributions / payments 19.0 49.4 Return on plan assets (1.3 ) 12.2 Benefits paid (26.3 ) (37.1 ) Spinoff of TimkenSteel — (143.9 ) Fair value of plan assets at end of year 112.1 120.7 Funded status at end of year $ (150.5 ) $ (163.9 ) Amounts recognized on the Consolidated Balance Sheets: Current liabilities $ (14.4 ) $ (22.1 ) Non-current liabilities (136.1 ) (141.8 ) $ (150.5 ) $ (163.9 ) Amounts recognized in accumulated other comprehensive loss: Net actuarial loss $ 19.2 $ 18.5 Net prior service cost 2.1 3.0 Accumulated other comprehensive loss $ 21.3 $ 21.5 Changes in plan assets and benefit obligations recognized in AOCL: AOCL at beginning of year $ 21.5 $ 13.3 Net actuarial loss 0.7 14.3 Recognized net actuarial loss (0.1 ) — Recognized prior service credit (0.8 ) (1.0 ) Spinoff of TimkenSteel — (5.1 ) Total recognized in accumulated other comprehensive loss at December 31 $ 21.3 $ 21.5 The presentation in the above tables for amounts recognized in accumulated other comprehensive loss on the Consolidated Balance Sheets is before the effect of income taxes. The following table summarizes assumptions used to measure the benefit obligation for the postretirement benefit plans at December 31 : Assumptions: 2015 2014 Discount rate 4.39 % 3.95 % The current portion of accrued postretirement benefit cost, which was included in salaries, wages and benefits on the Consolidated Balance Sheets, was $14.4 million and $22.1 million at December 31, 2015 and 2014 , respectively. In 2015 , the current portion of accrued postretirement benefit cost related to unfunded plans and represented the actuarial present value of expected payments related to the plans to be made over the next 12 months . The estimated net actuarial loss and prior service cost for the postretirement plans that will be amortized from accumulated other comprehensive loss into net periodic benefit cost over the next fiscal year are $0.1 million and $1.0 million of expense, respectively. For measurement purposes, the Company assumed a weighted-average annual rate of increase in the per capita cost (health care cost trend rate) for medical benefits of 6.75% for 2015, declining gradually to 5.0% in 2023 and thereafter; and 6.75% for 2015, declining gradually to 5.0% in 2023 and thereafter for prescription drug benefits; and 8.75% for 2015, declining gradually to 5.0% in 2031 and thereafter for HMO benefits. Most of the Company's postretirement plans include caps that limit the amount of the benefit provided by the Company to participants each year, which lessens the impact of health care inflation costs to the Company. The assumed health care cost trend rate may have a significant effect on the amounts reported. A one percentage point increase in the assumed health care cost trend rate would have increased the 2015 total service and interest cost components by $0.3 million and would have increased the postretirement benefit obligation by $6.4 million . A one percentage point decrease would provide corresponding reductions of $0.2 million and $5.7 million , respectively. The Medicare Prescription Drug, Improvement and Modernization Act of 2003 (the Medicare Act) provides for prescription drug benefits under Medicare Part D and contains a subsidy to plan sponsors who provide “actuarially equivalent” prescription plans. The Company’s actuary determined that the prescription drug benefit provided by the Company’s postretirement plan is considered to be actuarially equivalent to the benefit provided under the Medicare Act. In accordance with ASC Topic 715, “Compensation – Retirement Benefits,” all measures of the accumulated postretirement benefit obligation or net periodic postretirement benefit cost in the financial statements or accompanying notes reflect the effects of the Medicare Act on the plan for the entire fiscal year. The 2015 expected subsidy was $1.8 million , of which zero was received prior to December 31, 2015 . Plan Assets: The Company’s target allocation for the VEBA trust assets, as well as the actual VEBA trust asset allocation as of December 31, 2015 and 2014 , was as follows: Current Target Allocation Percentage of VEBA Assets at December 31, Asset Category 2015 2014 Equity securities 34% to 46% 42% 51% Debt securities 54% to 66% 58% 49% Total 100% 100% The Company recognizes its overall responsibility to ensure that the assets of its postretirement benefit plan are managed effectively and prudently and in compliance with its policy guidelines and all applicable laws. Preservation of capital is important; however, the Company 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 postretirement 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 portfolio is based on expected rates of return for various asset classes, as well as historical asset class and fund performance. The following table presents the fair value hierarchy for those investments of the Company’s VEBA trust assets measured at fair value on a recurring basis as of December 31, 2015 : Total Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 3.0 $ — $ 3.0 $ — Common collective fund - U.S. equities 28.2 — 28.2 — Common collective fund - international equities 18.3 — 18.3 — Common collective fund - fixed income 62.6 — 62.6 — Total Assets $ 112.1 $ — $ 112.1 $ — The following table presents the fair value hierarchy for those investments of the Company’s VEBA trust assets measured at fair value on a recurring basis as of December 31, 2014 : Total Level 1 Level 2 Level 3 Assets: Cash and cash equivalents $ 7.9 $ — $ 7.9 $ — Common collective fund - U.S. equities 39.9 — 39.9 — Common collective fund - international equities 22.1 — 22.1 — Common collective fund - fixed income 50.8 — 50.8 — Total Assets $ 120.7 $ — $ 120.7 $ — Cash and cash equivalents are valued at redemption value. Common collective funds are valued based on a net asset value per share, which is used as a practical expedient to fair value. When such prices are unavailable, the plan trustee determines a valuation from the market maker dealing in the particular security. Cash Flows: Employer Contributions to the VEBA Trust: 2014 $ 20.0 2015 — 2016 (planned) — Future benefit payments are expected to be as follows: Gross Expected Medicare Subsidies Net Including Medicare Subsidies 2016 $ 29.0 $ 1.7 $ 27.3 2017 27.7 1.7 26.0 2018 26.5 1.7 24.8 2019 25.1 1.7 23.4 2020 23.7 1.7 22.0 2021-2025 101.4 7.8 93.6

This segment also supports aftermarket sales and service needs through its global network of authorized industrial distributors. In addition, the Company’s industrial services group offers end users a broad portfolio of maintenance support and capabilities that include repair and service for bearings and gearboxes as well as electric motor rewind, repair and services. Measurement of segment profit or loss and segment assets: The Company evaluates performance and allocates resources based on return on capital and profitable growth. The primary measurement used by management to measure the financial performance of each segment is EBIT. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies. Factors used by management to identify the enterprise’s reportable segments: Net sales by geographic area are reported by the destination of net sales, which is reflective of how the Company operates its segments. Long-lived assets by geographic area are reported by the location of the subsidiary. Timken’s non-U.S. operations are subject to normal international business risks not generally applicable to a domestic business. These risks include currency fluctuation, changes in tariff restrictions, difficulties in establishing and maintaining relationships with local distributors and dealers, import and export licensing requirements, difficulties in staffing and managing geographically diverse operations and restrictive regulations by foreign governments, including price and exchange controls, compliance with a variety of foreign laws and regulations, including unexpected changes in taxation and environmental regulatory requirements, and disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including the FCPA.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income before income taxes, based on geographic location of the operations to which such earnings are attributable, is provided below. As the Company has elected to treat certain foreign subsidiaries as branches for U.S. income tax purposes, pretax income attributable to the United States shown below may differ from the pretax income reported in the Company’s annual U.S. Federal income tax return. (Loss) income from continuing operations before income taxes: 2015 2014 2013 United States $ (307.7 ) $ 39.5 $ 189.4 Non-United States 118.1 164.5 100.7 (Loss) income from continuing operations before income taxes $ (189.6 ) $ 204.0 $ 290.1 The (benefit) provision for income taxes consisted of the following: 2015 2014 2013 Current: Federal $ 26.8 $ 61.1 $ 96.8 State and local 5.4 2.8 11.5 Foreign 16.3 44.1 39.3 $ 48.5 $ 108.0 $ 147.6 Deferred: Federal $ (146.1 ) $ (46.9 ) $ (35.7 ) State and local (13.1 ) (4.4 ) 1.8 Foreign (10.9 ) (2.0 ) 0.9 $ (170.1 ) $ (53.3 ) $ (33.0 ) United States and foreign tax (benefit) expense on (loss) income $ (121.6 ) $ 54.7 $ 114.6 The Company made net income tax payments of $83.3 million , $111.6 million and $98.9 million in 2015 , 2014 and 2013 , respectively. The following table is the reconciliation between the (benefit) provision for income taxes and the amount computed by applying the U.S. Federal income tax rate of 35% to income before taxes: 2015 2014 2013 Income tax at the U.S. federal statutory rate $ (66.4 ) $ 71.4 $ 101.5 Adjustments: State and local income taxes, net of federal tax benefit (4.9 ) (0.3 ) 8.4 Tax on foreign remittances and U.S. tax on foreign income 13.8 19.6 41.0 Tax expense related to undistributed earnings of foreign subsidiaries — (8.7 ) 8.7 Foreign losses without current tax benefits 5.3 4.3 9.5 Foreign earnings taxed at different rates including tax holidays (11.0 ) (15.7 ) (3.9 ) U.S. domestic manufacturing deduction (4.5 ) (6.6 ) (8.8 ) U.S. foreign tax credit (22.4 ) (15.1 ) (25.9 ) U.S. research tax credit (1.1 ) (1.0 ) (3.2 ) Accruals and settlements related to tax audits (5.9 ) 12.8 (10.8 ) Reversal of valuation allowance (34.7 ) — — Deferred taxes related to branch operations 11.6 — — Other items, net (1.4 ) (6.0 ) (1.9 ) (Benefit) provision for income taxes $ (121.6 ) $ 54.7 $ 114.6 Effective income tax rate 64.1 % 26.8 % 39.5 % In connection with various investment arrangements, the Company has been granted a “holiday” from income taxes for one affiliate in Asia for 2015, 2014 and 2013. These agreements began to expire at the end of 2010, with full expiration in 2018. In total, the agreements reduced income tax expense by $1.3 million in 2015, $1.3 million in 2014 and $0.7 million in 2013. These savings resulted in an increase to earnings per diluted share of approximately $0.01 in 2015, approximately $0.01 in 2014 and approximately $0.01 in 2013. Income tax expense includes U.S. and international income taxes. At December 31, 2015 and December 31, 2014, the total amount of earnings planned to be reinvested outside of the U.S. were approximately $547.6 million and $486.7 million , respectively. The Company has determined that U.S. earnings are sufficient to cover U.S. cash needs for operations and foreign earnings will be reinvested outside the U.S. The Company intends to continue to make substantial investments to support the ongoing development and growth of our international operations. It is not practicable to calculate the deferred taxes that could be associated with the earnings indefinitely reinvested outside the U.S.; however, foreign tax credits would be available to reduce federal income taxes in the event of distribution. The effect of temporary differences giving rise to deferred tax assets and liabilities at December 31, 2015 and 2014 was as follows: 2015 2014 Deferred tax assets: Accrued postretirement benefits cost $ 72.3 $ 91.4 Accrued pension cost 36.3 16.3 Other employee benefit accruals 10.9 16.9 Tax loss and credit carryforwards 100.3 117.9 Other, net 40.0 60.0 Valuation allowances (83.7 ) (145.4 ) $ 176.1 $ 157.1 Deferred tax liabilities - principally depreciation and amortization (113.8 ) (100.3 ) Net deferred tax assets $ 62.3 $ 56.8 The Company has a U.S. foreign tax credit carryforward of $2.0 million that will begin to expire in 2023, and U.S. state and local credit carryforwards of $0.8 million , portions of which will expire in 2016. The Company also has U.S. state and local loss carryforwards with tax benefits totaling $1.5 million , portions of which will expire at the end of 2016. In addition, the Company has loss carryforwards in various non-U.S. jurisdictions with tax benefits totaling $95.9 million having various expiration dates, as well as tax credit carryforwards of $0.1 million . The Company has provided valuation allowances of $68.9 million against certain of these carryforwards. The majority of the non-U.S. loss carryforwards represent local country net operating losses for branches of the Company or entities treated as branches of the Company under U.S. tax law. Tax benefits have been recorded for these losses in the United States. The related local country net operating loss carryforwards are offset fully by valuation allowances. In addition to loss and credit carryforwards, the Company has provided valuation allowances of $14.8 million against other deferred tax assets. As of December 31, 2015, the Company had $50.4 million of total gross unrecognized tax benefits. Included in this amount was $38.0 million of unrecognized tax benefits that would favorably impact the Company’s effective income tax rate in any future periods if such benefits were recognized. As of December 31, 2015, the Company anticipates a decrease in its unrecognized tax positions of approximately $35.0 million to $40.0 million during the next 12 months. The anticipated decrease is primarily due to settlements with tax authorities and the expiration of various statutes of limitation. As of December 31, 2015, the Company had accrued $12.2 million of interest and penalties related to uncertain tax positions. The Company records interest and penalties related to uncertain tax positions as a component of income tax expense. As of December 31, 2014, the Company had $57.5 million of total gross unrecognized tax benefits. Included in this amount was $47.3 million of unrecognized tax benefits that would favorably impact the Company’s effective income tax rate in any future periods if such benefits were recognized. As of December 31, 2014, the Company had accrued $16.5 million of interest and penalties related to uncertain tax positions. As of December 31, 2013, the Company had $49.5 million of total gross unrecognized tax benefits. Included in this amount was $35.8 million of unrecognized tax benefits that would favorably impact the Company’s effective income tax rate in any future periods if such benefits were recognized. As of December 31, 2013, the Company had accrued $9.8 million of interest and penalties related to uncertain tax positions. The following table reconciles the Company’s total gross unrecognized tax benefits for the years ended December 31, 2015 , 2014 and 2013 : 2015 2014 2013 Beginning balance, January 1 $ 57.5 $ 49.5 $ 112.6 Tax positions related to the current year: Additions 6.5 0.7 9.3 Tax positions related to prior years: Additions 5.0 14.7 6.9 Reductions (4.0 ) (3.5 ) (1.4 ) Settlements with tax authorities (14.6 ) (3.0 ) (77.9 ) Lapses in statutes of limitation — (0.9 ) — Ending balance, December 31 $ 50.4 $ 57.5 $ 49.5 During 2015, gross unrecognized tax benefits decreased primarily due to settlements with tax authorities related to various prior year tax matters, including certain U.S. federal taxes, U.S. state and local taxes and taxes related to the Company’s international operations. These decreases were partially offset by accruals related to prior year tax matters, including certain U.S. federal taxes, U.S. state and local taxes and taxes related to the Company’s international operations. During 2014, gross unrecognized tax benefits decreased primarily due to net reductions related to various current year and prior year tax matters, including settlement of tax matters with government authorities and taxes related to the Company’s international operations. These decreases were partially offset by additions related to prior year tax matters, including certain U.S. federal taxes, U.S. state and local taxes and taxes related to the Company’s international operations. During 2013, gross unrecognized tax benefits decreased primarily due to net reductions related to various current year and prior year tax matters, including settlement of tax matters with government authorities and taxes related to the Company’s international operations. These decreases were partially offset by additions related to prior year tax matters, including certain U.S. federal taxes, U.S. state and local taxes and taxes related to the Company ’ s international operations. As of December 31, 2015, the Company was subject to examination by the IRS for tax years 2012 to the present. The Company was also subject to tax examination in various U.S. state and local tax jurisdictions for tax years 2006 to the present, as well as various foreign tax jurisdictions, including China, France, Germany, Italy, Mexico and India for tax years 2002 to the present. The current portion of the Company’s unrecognized tax benefits was presented on the Consolidated Balance Sheets within income taxes payable, and the non-current portion was presented as a component of other non-current liabilities.

Short-term investments are investments with maturities between four months and one year and are valued at amortized cost, which approximates fair value. The Company uses publicly available foreign currency forward and spot rates to measure the fair value of its foreign currency forward contracts. The Company does not believe it has significant concentrations of risk associated with the counterparts to its financial instruments. The following table presents those assets measured at fair value on a nonrecurring basis for the year ended December 31, 2015 using Level 3 inputs: Carrying Value Fair Value Adjustment Fair Value Long-lived assets held for sale: Repair business in Niles, Ohio $ 5.8 $ (3.0 ) $ 2.8 Total long-lived assets held for sale $ 5.8 $ (3.0 ) $ 2.8 Long-lived assets held and used: Fixed assets $ 0.8 $ (0.3 ) $ 0.5 Total long-lived assets held and used $ 0.8 $ (0.3 ) $ 0.5 Assets held for sale of $5.8 million associated with the Company's service center in Niles, Ohio were written down to their fair value of $2.8 million during the first quarter of 2015, resulting in an impairment charge of $3.0 million . The fair value of these assets was based on the price that the Company expected to receive from the sale of these assets. Various items of property, plant and equipment, with a carrying value of $0.8 million , were written down to their fair value of $0.5 million , resulting in an impairment charge of $0.3 million . The fair value for these assets was based on the price that would be received in a current transaction to sell the assets on a standalone basis, considering the age and physical attributes of these items, as these assets had been idled. The following table presents those assets measured at fair value on a nonrecurring basis for the year ended December 31, 2014 using Level 3 inputs: Carrying Value Fair Value Adjustment Fair Value Long-lived assets held for sale: Aerospace overhaul business $ 8.0 $ (1.2 ) $ 6.8 Total long-lived assets held for sale $ 8.0 $ (1.2 ) $ 6.8 Long-lived assets held and used: Goodwill $ 92.5 $ (86.3 ) $ 6.2 Indefinite-lived intangible assets 14.2 (5.5 ) 8.7 Amortizable intangible assets 4.4 (4.4 ) — Fixed assets 1.5 (1.5 ) — Total long-lived assets held and used $ 112.6 $ (97.7 ) $ 14.9 During 2014, assets held for sale of $8.0 million and assets held and used of $112.6 million were written down to their fair value of $6.8 million and $14.9 million , respectively, and impairment charges of $1.2 million and $97.7 million , respectively, were included in earnings. The fair value of these assets was based on the price that the Company expected to receive to sell these assets. On September 8, 2014, the Company announced plans to restructure its former rated substantially all aerospace activities into Mobile Industries under the direction of its Group President; (2) sold the assets of its aerospace engine overhaul business, located in Mesa, Arizona, during the fourth quarter of 2014; (3) evaluated strategic alternatives for its aerospace MRO parts business, also located in Mesa; and (4) announced plans to close its aerospace bearing facility located in Wolverhampton, U.K. by early 2016, rationalizing the capacity into existing facilities. In conjunction with the above Aerospace announcement, the Company reviewed goodwill for impairment for its Aerospace Transmissions and Aerospace Aftermarket reporting units. Step one of the goodwill impairment test failed for both of these reporting units. Therefore, the Company conducted step two of the goodwill impairment test. The carrying value of goodwill for the Aerospace Transmissions reporting unit was $56.9 million , and the carrying value of the Aerospace Aftermarket reporting unit was $35.6 million . The implied fair value of goodwill for the Aerospace Transmissions reporting unit was $1.7 million , and the implied fair value of the Aerospace Aftermarket reporting unit was $4.5 million . As a result of the carrying value of goodwill for these two reporting units exceeding fair value, the Company recorded a pretax impairment charge of $86.3 million during the third quarter of 2014. Indefinite-lived intangible assets that were classified as assets held and used associated with the Company's Aerospace Aftermarket reporting unit with a carrying value of $14.2 million were written down to their fair value of $8.7 million resulting in an impairment charge of $5.5 million . In conjunction with the above Aerospace announcement, the Company also reviewed indefinite-lived intangible assets within the Aerospace segment for impairment. The fair value for these intangible assets was based on a relief from royalty method. Intangible assets that were classified as assets held and used associated with the Company's Aerospace Aftermarket reporting unit with a carrying value of $4.4 million were written down to their fair value of zero resulting in an impairment charge of $4.4 million . The fair value for these intangible assets was based on the price that would be received in a current transaction to sell the assets on a standalone basis. Various items of property, plant and equipment, with a carrying value of $1.5 million , were written down to their fair value of zero , resulting in an impairment charge of $1.5 million . The fair value for these assets was based on the price that would be received in a current transaction to sell the assets on a standalone basis, considering the age and physical attributes of these items, as these assets had been idled. Financial Instruments: The Company’s financial instruments consist primarily of cash and cash equivalents, short-term investments, accounts receivable, net, accounts payable, trade, short-term borrowings and long-term debt. Due to their short-term nature, the carrying value of cash and cash equivalents, short-term investments, accounts receivable, net, accounts payable, trade and short-term borrowings are a reasonable estimate of their fair value. The fair value of the Company’s long-term fixed-rate debt, based on quoted market prices, was $521.5 million and $558.6 million at December 31, 2015 and 2014 , respectively. The carrying value of this debt was $520.4 million and $521.4 million at December 31, 2015 and 2014 , respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and hedging Activities Disclosure [Text Block]	Note 19 - Derivative Instruments and Hedging Activities The Company is exposed to certain risks relating to its ongoing business operations. The primary risks managed by using derivative instruments are foreign currency exchange rate risk, commodity price risk and interest rate risk. Forward contracts on various foreign currencies are entered into in order to manage the foreign currency exchange rate risk on forecasted revenue denominated in foreign currencies. Other forward exchange contracts on various foreign currencies are entered into in order to manage the foreign currency exchange rate risk associated with certain of the Company’s commitments denominated in foreign currencies. Forward contracts on various commodities are entered into in order to manage the price risk associated with forecasted purchases of natural gas used in the Company’s manufacturing process. Interest rate swaps are entered into to manage interest rate risk associated with the Company’s fixed and floating-rate borrowings. The Company designates certain foreign currency forward contracts as cash flow hedges of forecasted revenues and certain interest rate hedges as fair value hedges of fixed-rate borrowings. The majority of the Company’s natural gas forward contracts are not subject to any hedge designation as they are considered within the normal purchases exemption. The Company does not purchase or hold any derivative financial instruments for trading purposes. As of December 31, 2015 and 2014 , the Company had approximately $235.7 million and $194.1 million , respectively, of outstanding foreign currency forward contracts at notional value. Refer to Note 18 – Fair Value for the fair value disclosure of derivative financial instruments. Cash Flow Hedging Strategy: For certain derivative instruments that are designated as and qualify as cash flow hedges ( i.e ., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any ( i.e ., the ineffective portion), or hedge components excluded from the assessment of effectiveness, are recognized in the Consolidated Statement of Income during the current period. To protect against a reduction in the value of forecasted foreign currency cash flows resulting from export sales over the next year, the Company has instituted a foreign currency cash flow hedging program. The Company hedges portions of its forecasted intra-group revenue or expense denominated in foreign currencies with forward contracts. When the dollar strengthens significantly against foreign currencies, the decline in the present value of future foreign currency revenue is offset by gains in the fair value of the forward contracts designated as hedges. Conversely, when the dollar weakens, the increase in the present value of future foreign currency cash flows is offset by losses in the fair value of the forward contracts. The maximum length of time over which the Company hedges it exposure to the variability in future cash flows for forecasted transactions is generally eighteen months or less. Fair Value Hedging Strategy: For derivative instruments that are designated and qualify as fair value hedges ( i.e ., hedging the exposure to changes in the fair value of an asset or a liability or an identified portion thereof that is attributable to a particular risk), the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in the same line item associated with the hedged item ( i.e ., in “interest expense” when the hedged item is fixed-rate debt). Purpose for Derivative Instruments not designated as Hedging Instruments: For derivative instruments that are not designated as hedging instruments, the instruments are typically forward contracts. In general, the practice is to reduce volatility by selectively hedging transaction exposures including intercompany loans, accounts payable and accounts receivable. Intercompany loans between entities with different functional currencies are typically hedged with a forward contract at the inception of loan with a maturity date at the maturity of the loan. The revaluation of these contracts, as well as the revaluation of the underlying balance sheet items, is recorded directly to the income statement so the adjustment generally offsets the revaluation of the underlying balance sheet items to protect cash payments and reduce income statement volatility. The following table presents the fair value and location of all assets and liabilities associated with the Company's hedging instruments within the Consolidated Balance Sheets.

Significant Accounting Policies

Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Principles of Consolidation	The consolidated financial statements include the accounts and operations of the Company in which a controlling interest is maintained. Investments in affiliated companies that the Company does not control, and the activities of which it is not the primary beneficiary, are accounted for using the equity method. All intercompany accounts and transactions are eliminated upon consolidation.
Revenue Recognition, Services, Commissions [Policy Text Block]	The Company recognizes revenue when title passes to the customer. This occurs at the shipping point except for goods sold by certain foreign entities and certain exported goods, where title passes when the goods reach their destination. Selling prices are fixed based on purchase orders or contractual arrangements. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold in the Consolidated Statements of Income. The Company recognizes a portion of its revenues on the percentage-of-completion method measured on the cost-to-cost basis. In 2015 , 2014 and 2013 , the Company recognized $66 million , $50 million and $55 million , respectively, in net sales under the percentage-of-completion method.
Cash and Cash Equivalents, Policy [Policy Text Block]	The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Restricted Cash: Cash of $0.2 million and $15.3 million at December 31, 2015 and 2014, respectively, was restricted. The decrease was primarily due to cash restricted for workers compensation claims in 2014, which was replaced by a $14.5 million letter of credit in 2015.
Allowance for Doubtful Accounts	The Company maintains an allowance for doubtful accounts, which represents an estimate of the losses expected from the accounts receivable portfolio, to reduce accounts receivable to their net realizable value. The allowance is based upon historical trends in collections and write-offs, management’s judgment of the probability of collecting accounts and management’s evaluation of business risk. The Company extends credit to customers satisfying pre-defined credit criteria. The Company believes it has limited concentration of credit risk due to the diversity of its customer base.
Inventory, Policy [Policy Text Block]	Inventories are valued at the lower of cost or market. The majority of domestic inventories are valued by the LIFO method and the balance of the Company's inventories is valued by the FIFO method.
Investment, Policy [Policy Text Block]	Short-term investments are investments with maturities between four months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2015 and 2014 with a fair value and cost basis of $9.7 million and $8.4 million , respectively, which were included in other current assets on the Consolidated Balance Sheets.
Property, Plant and Equipment, Policy [Policy Text Block]	Property, plant and equipment, net is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed principally by the straight-line method based upon the estimated useful lives of the assets. The useful lives are approximately 30 years for buildings, three to ten years for computer software and three to 20 years for machinery and equipment. The impairment of long-lived assets is evaluated when events or changes in circumstances indicate that the carrying amount of the asset or related group of assets may not be recoverable. If the expected future undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized at that time to reduce the asset to the lower of its fair value or its net book value.
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Intangible assets subject to amortization are amortized on a straight-line method over their legal or estimated useful lives, with useful lives ranging from one to 20 years . Goodwill and indefinite-lived intangible assets not subject to amortization are tested for impairment at least annually. The Company performs its annual impairment test as of October 1, after the annual forecasting process is completed. Furthermore, goodwill and indefinite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying values may not be recoverable in accordance with accounting rules related to goodwill and other intangible assets.
Standard Product Warranty, Policy [Policy Text Block]	The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties based upon specific claims and a review of historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. The Company records and accounts for its warranty liability based on specific claim incidents. Should the Company become aware of a specific potential warranty claim for which liability is probable and reasonably estimable, a specific charge is recorded and accounted for accordingly. Adjustments are made quarterly to the accruals as claim data and historical experience change.
Income Tax, Policy [Policy Text Block]	The Company accounts for income taxes in accordance with ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss and tax credit carryforwards. The Company recognizes valuation allowances against deferred tax assets by tax jurisdiction when it is more likely than not that such assets will not be realized. Accruals for uncertain tax positions are provided for in accordance with ASC 740-10. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	$0.3 million , $9.9 million and $9.1 million for the years ended December 31, 2015 , 2014 and 2013 , respectively.
Pension and Other Postretirement Plans, Policy [Policy Text Block]	The Company recognizes an overfunded status or underfunded status (i.e., the difference between the fair value of plan assets and the benefit obligations) as either an asset or a liability for its defined benefit pension and postretirement benefit plans on the Consolidated Balance Sheets, with a corresponding adjustment to accumulated other comprehensive loss, net of tax. The adjustment to accumulated other comprehensive loss represents the current year net unrecognized actuarial gains and losses and unrecognized prior service costs. These amounts will be recognized in future periods as net periodic benefit cost.
Share-based Compensation, Option and Incentive Plans Policy [Policy Text Block]	The Company recognizes stock-based compensation expense based on the grant date fair value of the stock-based awards over their required vesting period. Stock options are issued with an exercise price equal to the opening market price of Timken common shares on the date of grant. The fair value of stock options is determined using a Black-Scholes option pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate and the expected dividend yield. The fair value of stock-based awards that will settle in Timken common shares, other than stock options, is based on the opening market price of Timken common shares on the grant date. The fair value of stock-based awards that will settle in cash are remeasured at each reporting period until settlement of the awards.
Earnings Per Share, Policy [Policy Text Block]	nvested restricted share grants provide for the payment of nonforfeitable dividends. The Company considers these awards as participating securities. Earnings per share are computed using the two-class method. Basic earnings per share are computed by dividing net income less undistributed earnings allocated to unvested restricted shares by the weighted-average number of common shares outstanding during the year. Diluted earnings per share are computed by dividing net income less undistributed earnings allocated to unvested restricted shares by the weighted-average number of common shares outstanding, adjusted for the dilutive impact of outstanding stock-based awards.
Derivatives, Policy [Policy Text Block]	The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. Derivatives that are not designated as hedges are adjusted to fair value through earnings. If the derivative is designated and qualifies as a hedge, depending on the nature of the hedge, changes in the fair value of the derivatives are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in accumulated other comprehensive loss until the hedged item is recognized in earnings. The Company’s holdings of forward foreign currency exchange contracts qualify as derivatives pursuant to the criteria established in derivative accounting guidance, and the Company has designated certain of those derivatives as hedges.
New Accounting Pronouncements, Policy [Policy Text Block]	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 the Company's operations and financial results should be presented as discontinued operations. ASU 2014-08 also requires expanded disclosures about discontinued operations that will provide financial statement users with more 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 this accounting guidance did not have any impact on the Company's results of operations or financial condition.
Use of Estimates, Policy [Policy Text Block]	The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Because actual results could differ from these estimates, the Company reviews and updated these estimates and assumptions regularly to reflect recent experience.
Significant Accounting Policies [Text Block]	Principles of Consolidation: The consolidated financial statements include the accounts and operations of the Company in which a controlling interest is maintained. Investments in affiliated companies that the Company does not control, and the activities of which it is not the primary beneficiary, are accounted for using the equity method. All intercompany accounts and transactions are eliminated upon consolidation. Revenue Recognition: The Company recognizes revenue when title passes to the customer. This occurs at the shipping point except for goods sold by certain foreign entities and certain exported goods, where title passes when the goods reach their destination. Selling prices are fixed based on purchase orders or contractual arrangements. Shipping and handling costs billed to customers are included in net sales and the related costs are included in cost of products sold in the Consolidated Statements of Income. The Company recognizes a portion of its revenues on the percentage-of-completion method measured on the cost-to-cost basis. In 2015 , 2014 and 2013 , the Company recognized $66 million , $50 million and $55 million , respectively, in net sales under the percentage-of-completion method. Cash Equivalents: The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Restricted Cash: Cash of $0.2 million and $15.3 million at December 31, 2015 and 2014, respectively, was restricted. The decrease was primarily due to cash restricted for workers compensation claims in 2014, which was replaced by a $14.5 million letter of credit in 2015. Allowance for Doubtful Accounts: The Company maintains an allowance for doubtful accounts, which represents an estimate of the losses expected from the accounts receivable portfolio, to reduce accounts receivable to their net realizable value. The allowance is based upon historical trends in collections and write-offs, management’s judgment of the probability of collecting accounts and management’s evaluation of business risk. The Company extends credit to customers satisfying pre-defined credit criteria. The Company believes it has limited concentration of credit risk due to the diversity of its customer base. Inventories: Inventories are valued at the lower of cost or market. The majority of domestic inventories are valued by the LIFO method and the balance of the Company's inventories is valued by the FIFO method. Investments: Short-term investments are investments with maturities between four months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2015 and 2014 with a fair value and cost basis of $9.7 million and $8.4 million , respectively, which were included in other current assets on the Consolidated Balance Sheets. Property, Plant and Equipment: Property, plant and equipment, net is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed principally by the straight-line method based upon the estimated useful lives of the assets. The useful lives are approximately 30 years for buildings, three to ten years for computer software and three to 20 years for machinery and equipment. The impairment of long-lived assets is evaluated when events or changes in circumstances indicate that the carrying amount of the asset or related group of assets may not be recoverable. If the expected future undiscounted cash flows are less than the carrying amount of the asset, an impairment loss is recognized at that time to reduce the asset to the lower of its fair value or its net book value. Goodwill and Other Intangible Assets: Intangible assets subject to amortization are amortized on a straight-line method over their legal or estimated useful lives, with useful lives ranging from one to 20 years . Goodwill and indefinite-lived intangible assets not subject to amortization are tested for impairment at least annually. The Company performs its annual impairment test as of October 1, after the annual forecasting process is completed. Furthermore, goodwill and indefinite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying values may not be recoverable in accordance with accounting rules related to goodwill and other intangible assets. Product Warranties: The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties based upon specific claims and a review of historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. The Company records and accounts for its warranty liability based on specific claim incidents. Should the Company become aware of a specific potential warranty claim for which liability is probable and reasonably estimable, a specific charge is recorded and accounted for accordingly. Adjustments are made quarterly to the accruals as claim data and historical experience change. Income Taxes: The Company accounts for income taxes in accordance with ASC 740, “Income Taxes.” Deferred tax assets and liabilities are recorded for the future tax consequences attributable to differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as net operating loss and tax credit carryforwards. The Company recognizes valuation allowances against deferred tax assets by tax jurisdiction when it is more likely than not that such assets will not be realized. Accruals for uncertain tax positions are provided for in accordance with ASC 740-10. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense. Foreign Currency: Assets and liabilities of subsidiaries are translated at the rate of exchange in effect on the balance sheet date; income and expenses are translated at the average rates of exchange prevailing during the reporting period. Related translation adjustments are reflected as a separate component of accumulated other comprehensive loss. Foreign currency gains and losses resulting from transactions are included in the Consolidated Statements of Income. The Company recognized a foreign currency exchange loss resulting from transactions of $0.3 million , $9.9 million and $9.1 million for the years ended December 31, 2015 , 2014 and 2013 , respectively. For the year ended December 31, 2015, the Company recorded a non-cash foreign currency translation adjustment of $71.5 million that decreased shareholders’ equity, compared with a non-cash foreign currency translation adjustment of $41.3 million that decreased shareholders’ equity for the year ended December 31, 2014. The foreign currency translation adjustments for the year ended December 31, 2015 were negatively impacted by the strengthening of the U.S. dollar relative to most other currencies. Pension and Other Postretirement Benefits: The Company recognizes an overfunded status or underfunded status (i.e., the difference between the fair value of plan assets and the benefit obligations) as either an asset or a liability for its defined benefit pension and postretirement benefit plans on the Consolidated Balance Sheets, with a corresponding adjustment to accumulated other comprehensive loss, net of tax. The adjustment to accumulated other comprehensive loss represents the current year net unrecognized actuarial gains and losses and unrecognized prior service costs. These amounts will be recognized in future periods as net periodic benefit cost. Net actuarial gains and losses for the Company's defined benefit pension plan in the United Kingdom are amortized over the remaining life expectancy of the participants in the plan. For all other plans, the Company generally amortizes actuarial gains and losses over the remaining service period of active participants. However, in accordance with its policy, the Company updates the census data for its U.S. defined benefit pension plans on an annual basis. The updated 2015 census data indicated that, as a result of the Spinoff, over 95% of the participants in one of the U.S. plans were inactive. Therefore, the Company changed the amortization period over which actuarial gains and losses related to that plan will be amortized to be based on the remaining expected life of inactive participants in the plan. This change resulted in an amortization period of 15.5 years, compared to 10.1 years had the change not been made. The impact of the change resulted in lower pension expense of $5.7 million ( $3.6 million after-tax, or $0.04 per share) for the first eleven months of 2015. On November 30, 2015, the Company purchased a group annuity contact from Prudential covering substantially all of the inactive participants in this plan. Refer to Note 14 - Retirement Benefit Plans for additional information. Subsequent to this transaction, the vast majority of the participants remaining in this plan were active. Therefore, the Company changed the amortization period back to the remaining service period of active participants in December 2015. Stock-Based Compensation: The Company recognizes stock-based compensation expense based on the grant date fair value of the stock-based awards over their required vesting period. Stock options are issued with an exercise price equal to the opening market price of Timken common shares on the date of grant. The fair value of stock options is determined using a Black-Scholes option pricing model, which incorporates assumptions regarding the expected volatility, the expected option life, the risk-free interest rate and the expected dividend yield. The fair value of stock-based awards that will settle in Timken common shares, other than stock options, is based on the opening market price of Timken common shares on the grant date. The fair value of stock-based awards that will settle in cash are remeasured at each reporting period until settlement of the awards. Earnings Per Share: Only certain unvested restricted share grants provide for the payment of nonforfeitable dividends. The Company considers these awards as participating securities. Earnings per share are computed using the two-class method. Basic earnings per share are computed by dividing net income less undistributed earnings allocated to unvested restricted shares by the weighted-average number of common shares outstanding during the year. Diluted earnings per share are computed by dividing net income less undistributed earnings allocated to unvested restricted shares by the weighted-average number of common shares outstanding, adjusted for the dilutive impact of outstanding stock-based awards. Derivative Instruments: The Company recognizes all derivatives on the Consolidated Balance Sheets at fair value. Derivatives that are not designated as hedges are adjusted to fair value through earnings. If the derivative is designated and qualifies as a hedge, depending on the nature of the hedge, changes in the fair value of the derivatives are either offset against the change in fair value of the hedged assets, liabilities or firm commitments through earnings or recognized in accumulated other comprehensive loss until the hedged item is recognized in earnings. The Company’s holdings of forward foreign currency exchange contracts qualify as derivatives pursuant to the criteria established in derivative accounting guidance, and the Company has designated certain of those derivatives as hedges. Recent Accounting Pronouncements: In November 2015, the Financial Accounting Standards Board (FASB) issued ASU 2015-17, "Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes." ASU 2015-17 requires entities to classify all deferred tax assets and liabilities as noncurrent on the balance sheet instead of separating deferred taxes into current and noncurrent amounts. Prior to the issuance of this new accounting guidance, entities were required to classify deferred tax assets and liabilities as current or noncurrent based on how the related assets or liabilities are classified. This new accounting guidance is effective for annual periods beginning after December 15, 2016. Early adoption of this new guidance is permitted. Effective October 1, 2015, the Company adopted ASU 2015-17 because the Company believes the adoption of ASU 2015-17 provides greater transparency to the overall presentation of deferred taxes. The Company adopted ASU 2015-17 on a prospective basis, and the Company did not retrospectively restate prior year amounts. In September 2015, the FASB issued ASU 2015-16, "Business Combinations (Topic 805): Simplifying the Accounting for Measurement-Period Adjustments." ASU 2015-16 eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Instead, acquirers must recognize measurement-period adjustments during the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. The new guidance does not eliminate the requirement for the measurement period to be completed within one year. This new accounting guidance is effective for annual periods beginning after December 15, 2015. The adoption of ASU 2015-16 is not expected to have a material impact on the Company's results of operations or financial condition. In May 2015, the FASB issued ASU 2015-07, "Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent)." ASU 2015-07 eliminates the requirement to categorize within the fair value hierarchy investments for which fair values are estimated using the net asset value (NAV) practical expedient provided in ASC 820, "Fair Value Measurement." Instead entities will be required to disclose the fair values of such investments so that financial statement users can reconcile amounts reported in the fair value hierarchy table and the amounts reported on the balance sheet. ASU 2015-07 is effective for fiscal years beginning after December 15, 2015, with retrospective application to all periods presented. Early adoption is permitted. The Company is currently evaluating the effect that the provisions of ASU 2015-07 will have on the Company's consolidated financial statements. The adoption of ASU 2015-07 is not expected to have an impact on the Company's results of operations or financial condition as the new guidance addresses disclosure only. In April 2015, the FASB issued ASU 2015-04, "Compensation - Retirement Benefits (Topic 715): Practical Expedient for the Measurement Date of an Employer's Defined Benefit Obligation and Plan Assets." ASU 2015-04 allows employers with fiscal year ends that do not coincide with a calendar month end to make an accounting policy election to measure defined benefit plan assets and obligations as of the end of the month closest to their fiscal year ends. Employers that elect to use this practical expedient must do so for all their defined benefit plans. In addition, all employers can elect to remeasure defined plan assets and obligations in interim periods at the closest calendar month end to an event that triggers a remeasurement, such as a plan settlement or curtailment. ASU 2015-04 is effective for public business entities in fiscal years beginning after December 15, 2015, with prospective application. Early adoption is permitted. Effective October 1, 2015, the Company adopted the provisions of ASU 2015-04 that allows an employer to remeasure defined benefit plan assets and obligations in interim periods at the closest month end to an event that triggers a remeasurement. The adoption of ASU 2015-04 had no effect on the Company's results of operations or financial condition. In April 2015, the FASB issued ASU 2015-03, "Interest - Imputation of Interest (Subtopic 835-30) - Simplifying the Presentation of Debt Issuance Costs." ASU 2015-03 requires that all costs incurred to issue debt be presented in the balance sheet as a direct deduction in the carrying value of debt. Prior to the issuance of this new accounting guidance, debt issuance costs were required to be presented in the balance sheet as a deferred charge (i.e., an asset), and only a debt discount was recorded as a direct deduction to the carrying value of debt. This new accounting guidance is effective for annual periods beginning after December 15, 2015. The adoption of ASU 2015-03 is not expected to have a material impact on the Company's results of operations or financial condition. In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)." ASU 2014-09 introduces a new five-step revenue recognition model in which an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU 2014-09 also requires disclosures sufficient to enable users to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers, including qualitative and quantitative disclosures about contracts with customers, significant judgments and changes in judgments and assets recognized from the costs to obtain or fulfill a contract. On July 9, 2015, the FASB decided to delay the effective date of this new accounting guidance by one year, which will result in it being effective for annual periods beginning after December 15, 2017. The Company is currently evaluating the impact of adopting ASU 2014-09 on the Company's results of operations or 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 the Company's operations and financial results should be presented as discontinued operations. ASU 2014-08 also requires expanded disclosures about discontinued operations that will provide financial statement users with more 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 this accounting guidance did not have any impact on the Company's results of operations or financial condition. Use of Estimates: The preparation of consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Because actual results could differ from these estimates, the Company reviews and updated these estimates and assumptions regularly to reflect recent experience. Reclassifications: Certain amounts reported in the 2014 and 2013 consolidated financial statements for segment results have been reclassified to conform to the current segment presentation.

The two group annuity contracts require Prudential to pay and administer future pension benefits for approximately 8,400 U.S. Timken retirees in the aggregate. The Company transferred a total of approximately $1.1 billion of its pension obligations and a total of approximately $1.2 billion of pension assets to Prudential in these transactions. In addition to the purchase of the group annuity contracts, the Company made lump-sum distributions of $37.2 million to new retirees in the U.S. The Company also entered into an agreement pursuant to which one of the Company's Canadian defined benefit pension plans purchased a group annuity contract from Canada Life. The group annuity contract requires Canada Life to pay and administer future pension benefits for approximately 40 Canadian retirees. As a result of the group annuity contracts, lump-sum distributions, as well as pension settlement and curtailment charges related to the Company's Canadian pension plans, the Company incurred total pension settlement and curtailment charges of $465.0 million , including professional fees of $2.6 million , in 2015. In 2014, the Company incurred pension settlement charges of $33.7 million , including professional fees, primarily to settle approximately $110 million of the Company's pension obligations related to one of its defined benefit pension plans in the U.S. as a result of the lump sum distributions for 2014 retirements and certain deferred vested plan participants. 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. The following table summarizes assumptions used to measure the benefit obligation for the defined benefit pension plans at December 31: Assumptions 2015 2014 U.S. Plans: Discount rate 4.69 % 4.20 % Future compensation assumption 2.00% to 3.00% 2.00% to 3.00% International Plans: Discount rate 2.00% to 8.50% 1.50% to 8.75% Future compensation assumption 2.20% to 8.00% 2.20% to 8.00%
