Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Employee Benefit Plans | Employee Benefit Plans Stock-Based Compensation Plans The Company maintains stock-based compensation plans primarily for its key employees and directors, although the plans permit awards to others expected to make significant contributions to the future of the Company. The plans authorize the compensation committee of the Company's board of directors (the board committee) to award a variety of stock and stock-based incentives, such as restricted stock, RSUs, nonqualified and incentive stock options, stock bonus shares, or performance-based shares. The award recipients and the terms of awards, including price, granted under these plans are determined by the board committee. Upon a change of control, as defined in the plans, all options or other awards become fully vested and all restrictions lapse. The Company had 486,681 shares available for grant under stock-based compensation plans at year-end 2017. The Company generally issues its common stock out of treasury stock, to the extent available, for share issuances related to its stock-based compensation plans. The Company recognizes compensation cost for all stock-based awards granted to employees and directors based on the grant date estimate of fair value for those awards. The fair value of RSUs is based on the grant date trading price of the Company's common stock, reduced by the present value of estimated dividends foregone during the requisite service period. The fair value of stock options is based on the Black-Scholes option-pricing model. The components of pre-tax stock-based compensation expense included in SG&A expenses in the accompanying consolidated statement of income are as follows:

Prior to 2016, the Company elected to recognize excess income tax benefits from stock option exercises and the vesting of RSUs in capital in excess of par value using the tax return ordering approach. The Company measured the tax benefit associated with excess tax deductions related to stock-based compensation expense by multiplying the excess tax deductions by the statutory tax rates. The Company recognized income tax benefits in capital in excess of par value of $881,000 in 2015 associated with stock-based compensation. As a result of the adoption of ASU No. 2016-09 in 2016, the Company did not recognize any income tax benefits in capital in excess of par value in 2017 and 2016. The Company grants RSUs to non-employee directors and certain employees. Holders of RSUs have no voting rights and are not entitled to receive cash dividends. Non-Employee Director Restricted Stock Units The Company granted 3,000 RSUs in 2017 and 5,000 RSUs in 2016 and 2015 to each of its non-employee directors. The RSUs vested ratably on the last day of each fiscal quarter within the year. The Company also granted 10,000 cash-settled RSUs to each of its non-employee directors in March 2015, which totaled 50,000 in the aggregate and had a grant date fair value of $2,279,000. No compensation expense was recognized as the RSUs would only have vested if a change in control as defined in the Company's 2006 equity incentive plan had occurred before the last day of the first quarter of 2020. During 2015, 10,000 RSUs were forfeited, and the remaining 40,000 RSUs were outstanding at year-end 2016. These remaining cash-settled RSUs were canceled without value in March 2017. Performance-Based Restricted Stock Units The Company grants performance-based RSUs to certain officers of the Company. Each performance-based RSU represents the right to receive one share of the Company's common stock upon vesting. The RSUs are subject to adjustment based on the achievement of a performance measure selected for the fiscal year, which historically has been a specified target for adjusted earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA) generated from continuing operations. Following adjustment, the RSUs are subject to additional time-based vesting, and vest in three equal annual installments, provided that the officer is employed by the Company on the applicable vesting dates. The Company recognizes compensation expense associated with performance-based RSUs ratably over the requisite service period for each separately-vesting portion of the award based on the grant date fair value, and net of actual forfeitures recorded when they occur. Compensation expense recognized is remeasured each reporting period until the total number of RSUs to be issued is known. Unrecognized compensation expense related to the unvested performance-based RSUs totaled approximately $2,124,000 at year-end 2017, and will be recognized over a weighted average period of 1.3 years. The performance-based RSU agreements provide for forfeiture in certain events, such as voluntary or involuntary termination of employment, and for acceleration of vesting in certain events, such as death, disability or a change in control of the Company. If death, disability, or a change in control occurs prior to the end of the performance period, the officer will receive the target RSU amount; otherwise, the officer will receive the number of deliverable RSUs based on the achievement of the performance goal, as stated in the RSU agreements. Time-Based Restricted Stock Units The Company grants time-based RSUs to its officers and other employees of the Company. Each time-based RSU represents the right to receive one share of the Company's common stock upon vesting. The Company recognizes compensation expense associated with these time-based RSUs ratably over the requisite service period for the entire award based on the grant date fair value, and net of actual forfeitures recorded when they occur. The time-based RSU agreement provides for forfeiture in certain events, such as voluntary or involuntary termination of employment, and for acceleration of vesting in certain events, such as death, disability, or a change in control of the Company. Unrecognized compensation expense related to the time-based RSUs totaled approximately $2,565,000 at year-end 2017, and will be recognized over a weighted average period of 1.8 years. A summary of the activity of the Company's unvested RSUs in 2017 is as follows:
|  | Units (In thousands) |  | Weighted Average Grant- Date Fair Value
Unvested RSUs at December 31, 2016 |  | 203 |  |  | $ | 40.23 |
Granted |  | 110 |  |  | $ | 59.30 |
Vested |  | (111 | ) |  | $ | 42.81 |
Forfeited / Expired |  | (3 | ) |  | $ | 43.75 |
Unvested RSUs at December 30, 2017 |  | 199 |  |  | $ | 49.32 |
The weighted-average grant date fair value of RSUs granted was $59.30 in 2017, $40.41 in 2016, and $44.75 in 2015. The total fair value of shares vested was $6,719,000 in 2017, $6,233,000 in 2016, and $7,502,000 in 2015. Stock Options The Company did not grant stock options during the last three fiscal years. Prior to 2014, the Company granted nonqualified stock options to its executive officers that vested over three years and were not exercisable until vested. All options awarded in prior periods were granted at an exercise price equal to the fair market value of the Company's common stock on the date of grant. Stock options vested in three equal annual installments beginning on the first anniversary of the grant date, provided that the recipient remained employed by the Company on the applicable vesting dates and expire on the ten th anniversary of the grant date. All outstanding stock options are fully vested. The Company recognized compensation expense associated with these stock options ratably over the requisite service period for the entire award based on the grant date fair value, and net of forfeitures. There was no unrecognized compensation expense related to these stock options at year-end 2017. The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option-pricing models require the input of highly subjective assumptions, including expected stock price volatility. Expected stock price volatility was calculated based on a review of the Company's actual historic stock prices commensurate with the expected life of the award. The expected option life was derived based on a review of the Company's historic option holding periods, including consideration of the holding period inherent in currently vested but unexercised options. The expected annual dividend rate was calculated by dividing the Company's annual dividend by the closing stock price on the grant date. The risk-free interest rate is based on the yield on zero-coupon U.S. Treasury securities for a period that is commensurate with the expected term of the option. The compensation expense recognized for these equity-based awards was net of estimated forfeitures. Forfeitures were estimated based on an analysis of actual option forfeitures. A summary of the Company's stock option activity in 2017 is as follows:

Modified Awards On September 20, 2017, the Company entered into an executive transition agreement with its vice president, general counsel and secretary in connection with her retirement on July 1, 2018. This agreement included provisions for post-employment compensation and modifications to outstanding equity awards. The Company will recognize $374,000 of post-employment compensation ratably through the retirement date. Pursuant to this agreement, all unvested RSUs vest at the retirement date. As of September 20, 2017, 4,254 RSUs were remeasured at a fair value of $93.82 per unit. The remaining compensation expense associated with the modified RSUs totaled $332,000 as of September 20, 2017, which will be recognized ratably through the retirement date. Employee Stock Purchase Plan The Company's eligible U.S. employees may elect to participate in its employee stock purchase plan. Under the plan, shares of the Company's common stock may be purchased at a 15% discount from the fair market value at the beginning or end of the purchase period, whichever is lower. Shares purchased under the plan are subject to a one-year resale restriction and are purchased through payroll deductions of up to 10% of each participating employee's gross wages. The Company issued 13,156 shares for 2017 (issued in 2018), 17,874 shares in 2016, and 13,573 shares in 2015 of its common stock under this plan. 401(k) Savings and Other Defined Contribution Plans The Company's U.S. subsidiaries participate in the Kadant Inc. 401(k) Retirement Savings Plan sponsored by the Company. Contributions to the plan are made by both the employee and the Company and are immediately vested. Company contributions are based upon the level of employee contributions. Certain of the Company's subsidiaries offer other retirement plans, the majority of which are defined contribution plans. Company contributions to these plans are based on formulas determined by the Company. For these plans, the Company contributed and charged to expense approximately $3,327,000 in 2017, $3,005,000 in 2016, and $2,749,000 in 2015. Pension and Other Post-Retirement Benefits Plans The Company sponsors a noncontributory defined benefit pension plan, which is closed to new participants, for eligible employees at one of its U.S. divisions and its corporate office. Certain of the Company’s non-U.S. subsidiaries also sponsor defined benefit pension plans covering certain employees at those subsidiaries. Funds for the U.S. pension plan and one of the non-U.S. pension plans are contributed to a trustee as necessary to provide for current service and for any unfunded projected benefit obligation over a reasonable period. The remaining non-U.S. pension plans are unfunded as permitted under their plans and applicable laws. Benefits under the Company’s pension plans are based on years of service and employee compensation. The Company also provides other post-retirement benefits under plans in the United States and at one of its non-U.S. subsidiaries. In addition, the Company provides for a restoration plan for certain executive officers which fully supplements benefits lost under the noncontributory defined benefit retirement plan as a consequence of applicable Internal Revenue Service limits and restores benefits for the limitation of years of service under the retirement plan. In accordance with ASC 715, "Compensation-Retirement Benefits," (ASC 715), the Company recognizes the funded status of its defined benefit pension and other post-retirement benefit plans as an asset or liability and changes in the funded status through AOCI, net of tax. The amounts in AOCI will be subsequently recognized as net periodic pension cost pursuant to the Company's historical accounting policy for amortizing such amounts. Further, actuarial gains and losses that arise in subsequent periods and are not recognized as net periodic pension cost in the same periods will be recognized as a component of AOCI, net of tax. The actuarial loss and prior service loss included in AOCI and expected to be recognized in net periodic benefit cost in 2018 are $665,000 and $93,000, respectively. The following table summarizes the change in benefit obligation; the change in plan assets; the unfunded status; and the amounts recognized in the accompanying consolidated balance sheet for the Company's U.S. and non-U.S. pension benefit plans and other post-retirement benefit plans. In accordance with ASU No. 2015-04, Compensation - Retirement Benefits (Topic 715), the Company elects to measure its plan assets and benefit obligations as of December 31.

The weighted-average assumptions used to determine the benefit obligation are as follows:
|  | U.S. Pension |  | Non-U.S. Pension |  | Other Post-Retirement
|  | December 30, 2017 |  | December 31, 2016 |  | December 30, 2017 |  | December 31, 2016 |  | December 30, 2017 |  | December 31, 2016

The discount rates for pension and other post-retirement plans are based on market yields on high-quality corporate bonds currently available and expected to be available during the period to maturity of the benefits. For pension and post-retirement plans that have been closed to new participants thereby shortening the duration, the discount rate is determined based on discounting the projected benefit streams against the Citigroup Pension discount curve. The projected benefit obligations and fair values of plan assets for the Company's pension plans with projected benefit obligations in excess of plan assets are as follows:

The weighted-average assumptions used to determine net periodic benefit cost are as follows:

In developing the overall expected long-term return on plan assets assumption, a building block approach was used in which rates of return in excess of inflation were considered separately for equity securities, debt securities, and other assets. The excess returns were weighted by the representative target allocation and added along with an appropriate rate of inflation to develop the overall expected long-term return on plan assets assumption. The Company believes this determination is consistent with ASC 715.

Description of Fair Value Measurements Level 1 – Quoted, active market prices for identical assets. Level 2 – Observable inputs other than Level 1 prices, based on model-derived valuations in which all significant inputs are observable in active markets. Level 3 – Unobservable inputs based on the Company's own assumptions. The following is a description of the valuation methodologies used for assets measured at fair value. There were no changes in valuation techniques during 2017 or 2016. Mutual funds - Investments in common stock index and fixed income funds. Share prices of the funds, referred to as a fund's Net Asset Value (NAV), are calculated daily based on the closing market prices and accruals of securities in the fund's total portfolio (total value of the fund) divided by the number of fund shares currently issued and outstanding. There are no redemption restrictions. Investments measured at NAV - Investments in common collective trusts that invest in a diversified blend of investment and non-investment grade fixed income securities and are valued at NAV provided by the fund administrator. The NAV is used as the practical expedient to estimate fair value. The NAVs of the funds are calculated monthly based on the closing market prices and accruals of securities in the fund's total portfolio (total value of the fund) divided by the number of fund shares currently issued and outstanding. Redemptions of the investments occur by contract at the respective fund's redemption date NAV. The Company has developed an investment policy for its U.S. noncontributory defined benefit retirement plan. The investment strategy is to emphasize total return, that is, the aggregate return from capital appreciation and dividend and interest income. The primary objective of the investment management for the plan's assets is the emphasis on consistent growth; specifically, growth in a manner that protects the plan's assets from excessive volatility in market value from year to year. The investment policy takes into consideration the benefit obligations, including timing of distributions. The following target asset allocation has been established for the plan:
Asset Category |  | Minimum |  | Neutral |  | Maximum
Equity Securities |  | 5 | % |  | 15 | % |  | 20 | %
Debt Securities |  | 80 | % |  | 85 | % |  | 95 | %
Total |  |  |  |  | 100 | % |  |  |
All equity securities must be drawn from recognized securities exchanges. Debt securities must be weighted to reflect a portfolio average maturity of not more than ten years, with average benchmark duration of five years. The credit quality must equal or exceed high investment grade quality ("Baa" or better). Cash Flows Contributions The Company does not plan to make any material cash contributions to its pension and post-retirement benefit plans in 2018 other than to fund current benefit payments. Estimated Future Benefit Payments Expected benefit payments are based on the same assumptions used to measure the Company's benefit obligation at year-end 2017. Estimated future benefit payments during the next five years and in aggregate for the five years thereafter are as follows:
|  |  |  |  |  | Other Post-retirement
