The Timken Company (the Company) has implemented changes to its
accounting principles for recognizing actuarial gains and losses
and returns on plan assets for the Company’s defined benefit
pension and other postretirement benefit plans effective January 1,
2017.

Prior to 2017, the Company amortized, as a component of pension and
other postretirement expense, unrecognized actuarial gains and
losses (included within accumulated other comprehensive income
(loss)) over the average remaining service period of active plan
participants, or average remaining life expectancy of inactive plan
participants when all or almost all of individual plan participants
are inactive. The Company also historically calculated the
market-related value of plan assets based on a five-year market
adjustment. Under the new principles, actuarial gains and losses
will be immediately recognized through net periodic benefit cost,
upon the annual remeasurement in the fourth quarter, or on an
interim basis if specific events trigger a remeasurement. In
addition, the Company has changed its accounting policy for
measuring the market-related value of plan assets from a calculated
amount (based on a five-year smoothing of asset returns) to fair
value.

Attached as Exhibit 99.1 to this Current Report on Form 8-K is
certain unaudited 2016 financial information (quarterly and annual)
presented as if the Company had reported its financial results for
the respective periods applying the new accounting principle.

This information shall not be deemed to be filed for the purposes
of Section 18 of the Securities Exchange Act of 1934 (the Exchange
Act) or otherwise subject to the liabilities of that section, nor
shall it be incorporated by reference into a filing under the
Securities Act of 1933, or the Exchange Act, except as shall be
expressly set forth by specific reference in such a filing.
