Opinion on the Financial Statements

We have audited the accompanying Statements of Net Assets Available for Benefits of The Timken Company Savings Plan for Certain Bargaining Associates (the “Plan”) as of December 31, 2017 and 2016, the related Statements of Changes in Net Assets for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2017 and 2016, and the changes in net assets available for benefits for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying Schedule of Assets (Held at End of Year) as of December 31, 2017 has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

We have served as the Plan’s auditor since 2016.

The Timken Company Savings Plan

for Certain Bargaining Associates

1. Description of the Plan

The following description of The Timken Company Savings Plan for Certain Bargaining Associates (the "Plan") provides only general information. Participants should refer to the Summary Plan Description for a more complete description of the Plan’s provisions. The Plan was established on February 16, 2003. On February 16, 2003, The Timken Company ("Timken" or the "Company") acquired Ingersoll-Rand Company Limited’s Engineered Solutions business, which was comprised of certain operating assets and subsidiaries including The Torrington Company. On July 1, 2013, Timken merged the Timken Gears & Services Savings Plan into the Plan.

General

During 2006, The Timken Company closed its Standard Plant, the full-time hourly employees of which were represented by the United Auto Workers Local 1645. As a result of this transaction, all participants in the Plan terminated their employment with The Timken Company and the Plan will no longer have any new participants or contributions from Local 1645. The Plan is a defined contribution plan which covered full-time hourly employees of Timken who are represented by the United Auto Workers (UAW) Local 864 and the International Association of Machinists (IAM) Local 311. Employees of Timken represented by UAW Local 864 and IAM Local 311 become eligible to participate in the Plan following the earlier of (i) being credited with one year of service or (ii) completion of 60 consecutive days of employment. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended ("ERISA").

Contributions

Under the provisions of the Plan, UAW Local 864 and IAM Local 311 participants are able to elect to contribute up to 18% of their eligible earnings on a pretax basis directly to the Plan subject to Internal Revenue Service ("IRS") limitations. Participants are also able to contribute amounts representing distributions from other qualified defined benefit or 401(k) defined contribution plans. For employees represented by UAW Local 864, Timken matches participant contributions, “Company Matching Contributions,” at an amount equal to 100% on the first 3% of the participant’s eligible earnings. The Plan also provides a "Company Non-elective Contribution," which is a 3% non-elective contribution for all employees represented by UAW 864. The compensation used to determine the Company Matching Contribution and the Company Non-elective Contribution for UAW Local 864 participants is equal to 100% of the employee's base hourly rate for the first forty hours per week plus 50% of overtime earnings.

Upon enrollment, a participant is required to direct his or her contribution in 1% increments to any of the Plan’s investment options. Participants have access to their account information and the ability to make changes on a daily basis, subject to the next available payroll for contribution change election, through an automated telecommunications system. Account information and certain changes may also be made through the Internet.

Participant Accounts

Each participant’s account is credited with the participant’s contributions and allocations of (a) Timken’s contributions and (b) Plan earnings, and is charged with an allocation of administrative expenses. Plan earnings are allocated based on the participant’s share of net earnings or losses of their respective elected investment options. Allocations of administrative expenses are based on the participant’s account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Vesting

Participants were immediately vested in their contributions and rollover contributions plus actual earnings thereon. Vesting in the Company Matching Contribution portion of their account plus actual earnings thereon is also immediate.

Notes Receivable from Participants

Participants may borrow from their account related to their participant contributions and rollover contributions with a minimum of $1,000 up to a maximum equal to the lesser of (1) $50,000 minus the excess of the highest outstanding loan balance during the past 12 months or (2) 50% of their vested account balance. Loan terms generally cannot exceed five years for general purpose loans and thirty years for residential loans.

The loans bear interest at an interest rate of 1% in excess of the prime rate, as published in the Wall Street Journal on the first business day of the month in which the loan is granted. Principal and interest are paid ratably through payroll deductions.

Payment of Benefits

Upon termination of service with The Timken Company, participants having a vested account balance greater than $1,000 are given the option of (i) transferring their account balance to another plan, (ii) receiving a lump-sum amount equal to the vested balance of their account, or (iii) leaving their vested account balance in the Plan (if vested account balance is greater than $5,000). Participants having a vested account balance less than $1,000 receive a lump-sum amount equal to their vested account balance. Participants with a vested account balance between $1,000 and $5,000 and who do not elect a distribution, are paid in a direct rollover to an individual retirement plan. Participants electing to leave their vested assets in the Plan may do so until age 70-1/2 after which time the lump-sum option would apply.

Hardship withdrawals are allowed for participants incurring an immediate and severe financial need, as defined by the Plan. Hardship withdrawals are strictly regulated by the IRS and a participant must exhaust all available loan options and distributions prior to requesting a hardship withdrawal.

Participants may elect to have their vested dividends in the Timken Company Common Stock Fund distributed to them in cash rather than automatically reinvested in common shares of the Company.

Administrative Expenses

The Plan's administrative expenses are paid by either the Plan or the Company, as provided by the Plan's provisions. Administrative expenses paid by the Company include recordkeeping and trustee fees. Expenses relating to purchases, sales or transfers of the Plan's investments are charged to the particular investment fund to which the expenses relate. All other administrative expenses of the Plan are paid by the Company. Expenses that are paid by the Company are excluded from these financial statements.

Plan Termination

Although it has not expressed any interest to do so, Timken has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, the Plan's trustee, Great-West Trust Company, LLC ("Trustee"), shall distribute to each participant the vested balance in their separate account.

2. Accounting Policies

Basis of Accounting

The financial statements have been prepared on the accrual basis of accounting.

Payment of Benefits

Benefits are recorded when paid.

Investment Valuation and Income Recognition

The Plan’s investments are stated at fair value and are invested in The Master Trust Agreement for the Timken Defined Contribution Plans ("Master Trust"), which was established for the investment of assets of the Plan and the two other defined contribution plans sponsored by The Timken Company.

The Trustee maintains a collective investment trust of common shares of The Timken Company within the Master Trust in which the Company’s defined contribution plans participate on a unit basis. Common shares of the Timken Company are traded on a national securities exchange and participation units in The Timken Company Common Stock Fund are valued at the last reported sales price on the last business day of the plan year.

Purchases and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date.

Notes Receivable from Participants

Participant notes receivable represents participant loans that are recorded at their unpaid principal balance plus any accrued but unpaid interest. Interest income on notes receivable from participants is recorded when it is earned. Related fees are recorded as administrative expenses and are expensed when they are incurred. No allowance for credit losses has been recorded as of December 31, 2017 or 2016. If a participant ceases to make loan repayments and the Plan Administrator deems the participant loan to be a distribution, the participant loan balance is reduced and a benefit payment is recorded.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles ("U.S. GAAP") requires management to make estimates that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

New Accounting Pronouncements

In February 2017, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2017-06, Plan Accounting: Defined Benefit Pension Plans (Topic 960), Defined Contribution Pension Plans (Topic 962), Health and Welfare Benefit Plans (Topic 965): Employee Benefit Plan Master Trust Reporting. For each master trust in which a plan holds an interest, ASU 2017-06 requires that a plan's interest in each master trust and any change in the interest in each master trust be presented in separate line items in the statement of net assets available for benefits and in the statement of changes in net assets available for benefits. ASU 2017-06 also removes the requirement to disclose the percentage interest in the master trust for plans with divided interests and requires that all plans disclose the dollar amount of their interest in each of those general types of investments, which supplements the existing requirement to disclose the master trusts balances in each general type of investments. In addition, ASU 2017-06 requires all plans to disclose (1) their master trust's other asset and liability balances and (2) the dollar amount of the plan's interest in each of those balances. ASU 2017-06 is effective for fiscal years beginning after December 15, 2018, with retrospective application to all periods presented. Early application is permitted. Management is currently evaluating the effect that the provisions of ASU 2017-06 will have on the Plan’s financial statements.

3. Investments

The Plan’s assets are held in the Master Trust, commingled with assets of other Company-sponsored benefit plans.

Each participating plan’s interest in the investment funds (i.e., separate accounts) of the Master Trust is based on account balances of the participants and their elected investment funds. The Master Trust assets are allocated among the participating plans by assigning to each plan those transactions (primarily contributions, benefit payments, and plan-specific expenses) that can be specifically identified and by allocating among all plans, in proportion to the fair value of the assets assigned to each plan, income and expenses resulting from the collective investment of the assets of the Master Trust. The Plan’s ownership percentage in the Master Trust as of December 31, 2017 and 2016 was 0.52% and 0.57%, respectively.

The following tables present the values of investments in the Master Trust and the Plan's ownership percentage in each investment fund of the Master Trust:

4. Fair Value

The fair value framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (level 1) and the lowest priority to unobservable inputs (level 3). The three levels of the fair value hierarchy under Accounting Standards Codification ("ASC") 820, Fair Value Measurements and Disclosures, are described as follows:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 - Inputs to the valuation methodology include:

•quoted prices for similar assets or liabilities in active markets;

•quoted prices for identical or similar assets or liabilities in inactive markets;

•inputs other than quoted prices that are observable for the asset or liability;

•inputs that are derived principally from or corroborated by observable market data by correlation or other means.

If the asset or liability has a specified (contractual) term, the level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of relevant observable inputs and minimize the use of unobservable inputs.

The following tables present the fair value hierarchy for those investment of the Master Trust measured at fair value on a recurring basis as of December 31, 2017 and 2016:

The Timken Company Savings Plan

for Certain Bargaining Associates

Notes to Financial Statements (continued)

The Timken Company and TimkenSteel Common Stock Funds participate in units and are valued based on the closing price of each company's common shares traded on a national securities exchange. Cash and cash equivalents and registered investment companies are valued based on quoted market prices reported on the active market on which the individual securities are traded.

As of December 31, 2016, the fair value of the cash and cash equivalents held in the Master Trust was presented as Level 2 assets. The prior year disclosure has been reclassified to present cash and cash equivalents as Level 1 assets due to readily observable market values.

The investment strategy for American Funds Washington Mutual Investors is to invest in common stocks of established companies that are listed on, or meet the financial listing requirements of, the New York Stock Exchange and have a strong record of earnings and dividends.

The T. Rowe Price Blue Chip Growth Trust seeks long-term growth of capital by investing primarily in common stocks of well-established large and medium-sized companies. Income is a secondary objective of the trust.

In 2017, the Vanguard Target Retirement Trust II Funds replaced the Vanguard Institutional Target Retirement Funds.

Notes to Financial Statements (continued)

5. Risks and Uncertainties

The Master Trust invests in various investment securities in line with participants' investment elections. Investment securities are exposed to various risks such as interest rate, market volatility, and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

6. Income Tax Status

The Plan has received a determination letter from the IRS dated August 7, 2017, stating that the Plan is qualified under Section 401(a) of the Internal Revenue Code (the "Code"), and therefore, the related trust is exempt from taxation. Subsequent to this determination by the IRS, the Plan was amended. Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Plan Administrator believes that the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan, as amended, is qualified and the related trust is tax-exempt. The Plan Administrator will take steps to ensure that the Plan's operations remain in compliance with the Code, including taking appropriate action, when necessary, to bring the Plan's operations into compliance.

Accounting principles generally accepted in the United States require plan management to evaluate uncertain tax positions taken by the Plan. The financial statement effects of a tax position are recognized when the position is more likely than not, based on the technical merits, to be sustained upon examination by the IRS. The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2017 and 2016, there are no uncertain positions taken or expected to be taken. The Plan has recognized no interest or penalties related to uncertain tax positions. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan Administrator believes it is no longer subject to income tax examinations for years prior to 2014.

7. Related-Party Transactions

Related-party transactions included the investments in the common stock of the Company and the investment funds of the Trustee. Such transactions are exempt from being prohibited transactions.

The following is a summary of transactions in Timken common shares with the Plan for the year ended December 31, 2017:



	Dollars
Purchased	$	10,144
Issued to participants for payment of benefits	$	76,878

Purchases and benefits paid to participants include Timken common shares valued at quoted market prices at the date of purchase or distribution.

Certain legal and accounting fees and certain administrative expenses relating to the maintenance of participant records are paid by the Company. Fees paid during the year for services rendered by parties in interest were based on customary and reasonable rates for such services.

8. Subsequent Events

Management evaluates subsequent events and transactions occurring subsequent to the date of the financial statements through the financial statement issuance date that affect recognition or disclosure to the financial statements. No subsequent events were identified.
