Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]

Note 1 - Significant Accounting Policies

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 where the Company exercises significant influence, but 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:

A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Revenue is recognized when performance obligations under the terms of a contract with a customer of the Company are satisfied. Of the Company's revenue, approximately 85-90% is from short-term, fixed-price contracts and continues to be recognized as of a point in time when products are shipped from the Company's manufacturing facilities or at a later point in time when control of the products transfers to the customer. In accordance with applicable accounting guidance adopted by the Company on January 1, 2018 and applied on a modified retrospective basis, the Company recognizes approximately 10-15% of revenue over time for services and certain sales of customer-specific product as it satisfies the performance obligations because of the continuous transfer of control to the customer, supported as follows:

• For certain service contracts, this continuous transfer of control to the customer occurs as the Company's service enhances assets that the customer owns and controls at all times and the Company is contractually entitled to payment for work performed to date plus a reasonable margin.

• For U.S. government contracts, the customer is allowed to unilaterally terminate the contract for convenience, and is required to pay the Company for costs incurred plus a reasonable margin and can take control of any work in process.

• For certain non-U.S. government contracts involving customer-specific products, the customer controls the work in process based on contractual termination clauses or restrictions on the Company's use of the product and the Company possesses a right to payment for work performed to date plus a reasonable margin.

As a result of control transferring over time for these products and services, revenue is recognized based on progress toward completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company has elected to use the cost-to-cost input measure of progress for these contracts because it best depicts the transfer of goods or services to the customer based on incurring costs on the contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

The pricing and payment terms for non-U.S. government contracts are based on the Company's standard terms and conditions or the result of specific negotiations with each customer. The Company's standard terms and conditions require payment 30 days from the invoice date, but the timing of payment for specific negotiated terms may vary. The Company also has both prime and subcontracts in support of the provision of goods and services to the U.S. government. Certain of these contracts are subject to the Federal Acquisition Regulation ("FAR") and are priced commercially based on a competitive market. Under the payment terms of those U.S. government fixed-price contracts, the customer pays the Company performance-based payments, which are interim payments of up to 80% of the contract price for costs incurred to date based on quantifiable measures of performance or on the achievement of specified events or milestones. Because the customer retains a portion of the contract price until completion of such contracts, certain of these U.S. government fixed-price contracts result in revenue recognized in excess of billings, which is presented within "Unbilled Receivables" on the Consolidated Balance Sheet. The portion of the payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. As a practical expedient, the Company may exclude an assessment of whether promised goods or services are performance obligations, if such promised goods and services are immaterial to the customer contract taken as a whole, and combine these with other performance obligations. The Company has also elected not to adjust the promised amount of consideration for the effects of any significant financing component where the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Finally, the Company's policy is to exclude performance obligations resulting from contracts with a duration of one year or less from its disclosures related to remaining performance obligations.

The amount of consideration to which the Company expects to be entitled in exchange for the goods and services is not generally subject to significant variations. However, the Company does offer certain customers rebates, prompt payment discounts, end-user discounts, the right to return eligible products, and/or other forms of variable consideration. The Company estimates this variable consideration using the expected value amount, which is based on historical experience. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company adjusts the estimate of revenue at the earlier of when the amount of consideration the Company expects to receive changes or when the consideration becomes fixed. The Company recognizes the cost of freight and shipping when control of the products or services has transferred to the customer as an expense in "Cost of products sold" on the Consolidated Statement of Income, because those are costs incurred to fulfill the promise recognized, not a separate performance obligation. To the extent certain freight and shipping fees are charged to customers, the Company recognizes the amounts charged to customers as revenues and the related costs as an expense in "Cost of products sold" when control of the related products or services has transferred to the customer.

Contracts are occasionally modified to account for changes in contract specifications, requirements, and pricing. The Company considers contract modifications to exist when the modification either creates new enforceable rights and obligations or changes existing ones. Substantially all of the Company's contract modifications are for goods or services that are distinct from the existing contract. Therefore, the effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates is generally recognized on a prospective basis.

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 $6.7 million and $0.6 million at December 31, 2019 and 2018, respectively, was restricted for contractually specified uses. The increase was primarily due to the Company's contractual hold-back of cash for potential working capital adjustments as part of the BEKA acquisition.

Accounts Receivable, Less Allowances:

Accounts receivable, less allowances on the Consolidated Balance Sheet include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. 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.

Unbilled Receivables:

Unbilled receivables on the Consolidated Balance Sheet primarily include unbilled amounts typically resulting from sales under long-term contracts when the following conditions exist: (i) cost-to-cost method of revenue recognition is utilized; (ii) the revenue recognized exceeds the amount billed to the customer; and (iii) the right to payment is primarily subject only to the passage of time. The amounts recorded for unbilled amounts do not exceed their net realizable value.

Inventories:

Inventories are valued at the lower of cost or net realizable value, with approximately 59% valued by the FIFO method and the remaining 41% valued by the LIFO method. The majority of the Company’s domestic inventories are valued by the LIFO method, while all of the Company’s international inventories are valued by the FIFO method.

Investments:

Short-term investments are investments with maturities between three months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2019 and 2018 with a fair value and cost basis of $25.8 million and $21.8 million, respectively, which were included in "Other current assets" on the Consolidated Balance Sheets.

Property, Plant and Equipment:

Property, plant and equipment, net on the Consolidated Balance Sheets is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed 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 10 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 1st. Furthermore, goodwill and 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.

Purchase accounting and business combinations:

Assets acquired and the liabilities assumed as part of a business combination are recognized at their acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. The Company considers inputs to value the assets and liabilities by taking into account competitive trends, market comparisons, independent appraisals, and historical data, among other factors, as supplemented by current and anticipated market conditions. The valuation inputs in these analyses are based on market participant assumptions. The Company may refine these estimates and record adjustments to an asset or liability with the offset to goodwill during the measurement period, which may be up to one year from the acquisition date. Upon the conclusion of the measurement period or final determination of the values of the assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded in the Company’s Consolidated Statements of Income.

Product Warranties:

The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties generally based upon specific claims and in certain instances based on historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. When the Company becomes 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 those 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. Translation adjustments for assets and liabilities 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. Net of related derivative activity, the Company recognized a foreign currency exchange gain resulting from transactions of $6.1 million for the year ended December 31, 2019, and recognized a gain of $3.6 million and a loss of $3.7 million for the years ended December 31, 2018 and 2017, respectively.

Pension and Other Postretirement Benefits:

The Company recognizes actuarial gains and losses immediately through net periodic benefit cost upon the annual remeasurement in the fourth quarter, or on an interim basis if specific events trigger a remeasurement.

With the adoption of Accounting Standards Update ("ASU") 2017-07 on January 1, 2018, service cost is included in other employee compensation costs within operating income and is the only component of net periodic benefit cost that may be capitalized when applicable. The other components of net periodic benefit cost are presented outside of operating income. Also, actuarial gains and losses are excluded from segment results, while all other components of net periodic benefit cost will continue to be included within segment results. These changes in accounting principles were applied retrospectively; therefore, prior period amounts impacted have been revised accordingly herein. For further information, refer to the description of new accounting guidance adopted below.

Stock-Based Compensation:

The Company recognizes stock-based compensation expense over the related vesting period of the awards based on the fair value on the grant date. 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.

Use of Estimates:

The preparation of consolidated financial statements in conformity with U.S. GAAP 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 updates these estimates and assumptions regularly to reflect recent experience.

Recent Accounting Pronouncements:

New Accounting Guidance Adopted:

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 was issued to increase transparency and comparability among entities by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. The Company adopted the new leasing standard on January 1, 2019 using the cumulative-effect adjustment transition method. The Company also elected several practical expedients to not asses the following as part of adoption: (1) whether any expired or existing contracts contain leases; (2) the lease classification between finance and operating leases for any expired or existing leases; and (3) the recognition of initial direct costs for existing leases. The Company also elected to not recognize leases with a term of 12 months or less on the Consolidated Balance Sheets. The adoption of the lease standard had no impact to the Company's consolidated results of operations or the captions on the consolidated statements of cash flows. The cumulative effect of the changes made to the balance sheet as of January 1, 2019 for the adoption of the new lease standard was as follows:

	Balance at December 31, 2018		Effect of Accounting Change			Balance at January 1, 2019
Operating lease assets	$	—	$	114.1		$	114.1
Other intangible assets	733.2		0.7			733.9
Other non-current assets (1)	37.0		(15.3		)	21.7
Total Assets	4,445.2		99.5			4,544.7
Short-term operating lease liability	—		29.8			29.8
Long-term operating lease liability	—		69.7			69.7
Total Liabilities	$	2,802.5	$	99.5		$	2,902.0

⁽¹⁾ Due to the adoption of the new leasing standard, the Company recognized operating lease assets and corresponding operating lease liabilities on the Consolidated Balance Sheet. In conjunction with the adoption of the new leasing standard, the Company reclassified $15.3 million of lease assets related to purchase accounting adjustments from the ABC Bearings acquisition from Other assets to Operating lease assets. These assets do not have material corresponding lease liabilities.

The Company determines if any arrangement is a lease at the inception of a contract. For leases where the Company is the lessee, it recognizes lease assets and related lease liabilities at the lease commencement date based on the present value of lease payments over the lease term. Most of the Company’s leases do not provide an implicit interest rate. As a result, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease assets also consist of amounts for favorable or unfavorable lease terms related to acquisitions. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition. A lease asset and lease liability are not recorded for leases with an initial term of less than 12 months or less and the lease expenses related to these leases is recognized as incurred over the lease term.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities", which impacts both designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. ASU 2017-12 amends and clarifies the requirements to qualify for hedge accounting, removes the requirement to recognize changes in fair value from certain hedges in current earnings, and specifies the presentation of changes in fair value in the income statement for all hedging instruments. ASU 2017-12 is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-12 effective January 1, 2019, and the impact of adoption was not material to the Company's results of operations and financial condition.

New Accounting Guidance Issued and Not Yet Adopted:

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade, unbilled and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. ASU 2016-13 is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Based on the Company's analysis, ASU 2016-13 did not have a material impact on the Company's results of operations and financial condition upon adoption on January 1, 2020.

Investment, Policy [Policy Text Block]

Investments:

Short-term investments are investments with maturities between three months and one year and are valued at amortized cost, which approximates fair value. The Company held short-term investments as of December 31, 2019 and 2018 with a fair value and cost basis of $25.8 million and $21.8 million, respectively, which were included in "Other current assets" on the Consolidated Balance Sheets.

Principles of Consolidation

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 where the Company exercises significant influence, but 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 [Policy Text Block]

Revenue:

A contract exists when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable.

Revenue is recognized when performance obligations under the terms of a contract with a customer of the Company are satisfied. Of the Company's revenue, approximately 85-90% is from short-term, fixed-price contracts and continues to be recognized as of a point in time when products are shipped from the Company's manufacturing facilities or at a later point in time when control of the products transfers to the customer. In accordance with applicable accounting guidance adopted by the Company on January 1, 2018 and applied on a modified retrospective basis, the Company recognizes approximately 10-15% of revenue over time for services and certain sales of customer-specific product as it satisfies the performance obligations because of the continuous transfer of control to the customer, supported as follows:

• For certain service contracts, this continuous transfer of control to the customer occurs as the Company's service enhances assets that the customer owns and controls at all times and the Company is contractually entitled to payment for work performed to date plus a reasonable margin.

• For U.S. government contracts, the customer is allowed to unilaterally terminate the contract for convenience, and is required to pay the Company for costs incurred plus a reasonable margin and can take control of any work in process.

• For certain non-U.S. government contracts involving customer-specific products, the customer controls the work in process based on contractual termination clauses or restrictions on the Company's use of the product and the Company possesses a right to payment for work performed to date plus a reasonable margin.

As a result of control transferring over time for these products and services, revenue is recognized based on progress toward completion of the performance obligation. The selection of the method to measure progress towards completion requires judgment and is based on the nature of the products or services to be provided. The Company has elected to use the cost-to-cost input measure of progress for these contracts because it best depicts the transfer of goods or services to the customer based on incurring costs on the contracts. Under the cost-to-cost measure of progress, the extent of progress towards completion is measured based on the ratio of costs incurred to date to the total estimated costs at completion of the performance obligation. Revenues are recorded proportionally as costs are incurred.

The pricing and payment terms for non-U.S. government contracts are based on the Company's standard terms and conditions or the result of specific negotiations with each customer. The Company's standard terms and conditions require payment 30 days from the invoice date, but the timing of payment for specific negotiated terms may vary. The Company also has both prime and subcontracts in support of the provision of goods and services to the U.S. government. Certain of these contracts are subject to the Federal Acquisition Regulation ("FAR") and are priced commercially based on a competitive market. Under the payment terms of those U.S. government fixed-price contracts, the customer pays the Company performance-based payments, which are interim payments of up to 80% of the contract price for costs incurred to date based on quantifiable measures of performance or on the achievement of specified events or milestones. Because the customer retains a portion of the contract price until completion of such contracts, certain of these U.S. government fixed-price contracts result in revenue recognized in excess of billings, which is presented within "Unbilled Receivables" on the Consolidated Balance Sheet. The portion of the payments retained by the customer until final contract settlement is not considered a significant financing component because the intent is to protect the customer.

Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring goods or providing services. Sales, value add, and other taxes the Company collects concurrent with revenue-producing activities are excluded from revenue. As a practical expedient, the Company may exclude an assessment of whether promised goods or services are performance obligations, if such promised goods and services are immaterial to the customer contract taken as a whole, and combine these with other performance obligations. The Company has also elected not to adjust the promised amount of consideration for the effects of any significant financing component where the Company expects, at contract inception, that the period between when the Company transfers a promised good or service to a customer and when the customer pays for that good or service will be one year or less. Finally, the Company's policy is to exclude performance obligations resulting from contracts with a duration of one year or less from its disclosures related to remaining performance obligations.

The amount of consideration to which the Company expects to be entitled in exchange for the goods and services is not generally subject to significant variations. However, the Company does offer certain customers rebates, prompt payment discounts, end-user discounts, the right to return eligible products, and/or other forms of variable consideration. The Company estimates this variable consideration using the expected value amount, which is based on historical experience. The Company includes estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. The Company adjusts the estimate of revenue at the earlier of when the amount of consideration the Company expects to receive changes or when the consideration becomes fixed. The Company recognizes the cost of freight and shipping when control of the products or services has transferred to the customer as an expense in "Cost of products sold" on the Consolidated Statement of Income, because those are costs incurred to fulfill the promise recognized, not a separate performance obligation. To the extent certain freight and shipping fees are charged to customers, the Company recognizes the amounts charged to customers as revenues and the related costs as an expense in "Cost of products sold" when control of the related products or services has transferred to the customer.

Contracts are occasionally modified to account for changes in contract specifications, requirements, and pricing. The Company considers contract modifications to exist when the modification either creates new enforceable rights and obligations or changes existing ones. Substantially all of the Company's contract modifications are for goods or services that are distinct from the existing contract. Therefore, the effect of a contract modification on the transaction price and the Company's measure of progress for the performance obligation to which it relates is generally recognized on a prospective basis.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Cash Equivalents:

The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.

Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]

Restricted Cash:

Cash of $6.7 million and $0.6 million at December 31, 2019 and 2018, respectively, was restricted for contractually specified uses. The increase was primarily due to the Company's contractual hold-back of cash for potential working capital adjustments as part of the BEKA acquisition.

Allowance for Doubtful Accounts

Accounts Receivable, Less Allowances:

Accounts receivable, less allowances on the Consolidated Balance Sheet include amounts billed and currently due from customers. The amounts due are stated at their net estimated realizable value. 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:

Inventories are valued at the lower of cost or net realizable value, with approximately 59% valued by the FIFO method and the remaining 41% valued by the LIFO method. The majority of the Company’s domestic inventories are valued by the LIFO method, while all of the Company’s international inventories are valued by the FIFO method.

Property, Plant and Equipment, Policy [Policy Text Block]

Property, Plant and Equipment:

Property, plant and equipment, net on the Consolidated Balance Sheets is valued at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred. The provision for depreciation is computed 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 10 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]

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 1st. Furthermore, goodwill and 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]

Product Warranties:

The Company provides limited warranties on certain of its products. The Company accrues liabilities for warranties generally based upon specific claims and in certain instances based on historical warranty claim experience in accordance with accounting rules relating to contingent liabilities. When the Company becomes 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]

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 those 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]

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. Translation adjustments for assets and liabilities 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. Net of related derivative activity, the Company recognized a foreign currency exchange gain resulting from transactions of $6.1 million for the year ended December 31, 2019, and recognized a gain of $3.6 million and a loss of $3.7 million for the years ended December 31, 2018 and 2017, respectively.

Pension and Other Postretirement Plans, Policy [Policy Text Block]

Pension and Other Postretirement Benefits:

The Company recognizes actuarial gains and losses immediately through net periodic benefit cost upon the annual remeasurement in the fourth quarter, or on an interim basis if specific events trigger a remeasurement.

With the adoption of Accounting Standards Update ("ASU") 2017-07 on January 1, 2018, service cost is included in other employee compensation costs within operating income and is the only component of net periodic benefit cost that may be capitalized when applicable. The other components of net periodic benefit cost are presented outside of operating income. Also, actuarial gains and losses are excluded from segment results, while all other components of net periodic benefit cost will continue to be included within segment results. These changes in accounting principles were applied retrospectively; therefore, prior period amounts impacted have been revised accordingly herein. For further information, refer to the description of new accounting guidance adopted below.

Share-based Payment Arrangement [Policy Text Block]

Stock-Based Compensation:

The Company recognizes stock-based compensation expense over the related vesting period of the awards based on the fair value on the grant date. 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]

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.

Derivatives, Policy [Policy Text Block]

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.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates:

The preparation of consolidated financial statements in conformity with U.S. GAAP 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 updates these estimates and assumptions regularly to reflect recent experience.

New Accounting Pronouncements, Policy [Policy Text Block]

New Accounting Guidance Adopted:

In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)." ASU 2016-02 was issued to increase transparency and comparability among entities by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about lease arrangements. The Company adopted the new leasing standard on January 1, 2019 using the cumulative-effect adjustment transition method. The Company also elected several practical expedients to not asses the following as part of adoption: (1) whether any expired or existing contracts contain leases; (2) the lease classification between finance and operating leases for any expired or existing leases; and (3) the recognition of initial direct costs for existing leases. The Company also elected to not recognize leases with a term of 12 months or less on the Consolidated Balance Sheets. The adoption of the lease standard had no impact to the Company's consolidated results of operations or the captions on the consolidated statements of cash flows. The cumulative effect of the changes made to the balance sheet as of January 1, 2019 for the adoption of the new lease standard was as follows:

	Balance at December 31, 2018		Effect of Accounting Change			Balance at January 1, 2019
Operating lease assets	$	—	$	114.1		$	114.1
Other intangible assets	733.2		0.7			733.9
Other non-current assets (1)	37.0		(15.3		)	21.7
Total Assets	4,445.2		99.5			4,544.7
Short-term operating lease liability	—		29.8			29.8
Long-term operating lease liability	—		69.7			69.7
Total Liabilities	$	2,802.5	$	99.5		$	2,902.0

⁽¹⁾ Due to the adoption of the new leasing standard, the Company recognized operating lease assets and corresponding operating lease liabilities on the Consolidated Balance Sheet. In conjunction with the adoption of the new leasing standard, the Company reclassified $15.3 million of lease assets related to purchase accounting adjustments from the ABC Bearings acquisition from Other assets to Operating lease assets. These assets do not have material corresponding lease liabilities.

The Company determines if any arrangement is a lease at the inception of a contract. For leases where the Company is the lessee, it recognizes lease assets and related lease liabilities at the lease commencement date based on the present value of lease payments over the lease term. Most of the Company’s leases do not provide an implicit interest rate. As a result, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The lease assets also consist of amounts for favorable or unfavorable lease terms related to acquisitions. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense using the accelerated interest method of recognition. A lease asset and lease liability are not recorded for leases with an initial term of less than 12 months or less and the lease expenses related to these leases is recognized as incurred over the lease term.

In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities", which impacts both designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. ASU 2017-12 amends and clarifies the requirements to qualify for hedge accounting, removes the requirement to recognize changes in fair value from certain hedges in current earnings, and specifies the presentation of changes in fair value in the income statement for all hedging instruments. ASU 2017-12 is effective for public companies for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company adopted ASU 2017-12 effective January 1, 2019, and the impact of adoption was not material to the Company's results of operations and financial condition.

New Accounting Guidance Issued and Not Yet Adopted:

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". ASU 2016-13 changes how entities will measure credit losses for most financial assets and certain other instruments that are not measured at fair value through net income. The new guidance will replace the current incurred loss approach with an expected loss model. The new expected credit loss impairment model will apply to most financial assets measured at amortized cost and certain other instruments, including trade, unbilled and other receivables, loans, held-to-maturity debt instruments, net investments in leases, loan commitments and standby letters of credit. Upon initial recognition of the exposure, the expected credit loss model requires entities to estimate the credit losses expected over the life of an exposure (or pool of exposures). The estimate of expected credit losses should consider historical information, current information and reasonable and supportable forecasts, including estimates of prepayments. Financial instruments with similar risk characteristics should be grouped together when estimating expected credit losses. ASU 2016-13 does not prescribe a specific method to make the estimate, so its application will require significant judgment. ASU 2016-13 is effective for public companies in fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Based on the Company's analysis, ASU 2016-13 did not have a material impact on the Company's results of operations and financial condition upon adoption on January 1, 2020.
