Share-Based Compensation

Our shareholders approved and ratified the 2014 Omnibus Share Incentive Plan (the “2014 Plan”), which allows us to grant equity-based compensation awards, including stock options, restricted stock awards and restricted stock units including performance stock units. We disclosed the significant terms of the 2014 Plan and prior plans in the notes to our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 29, 2017.

Stock-based compensation expense related to stock options, restricted stock awards ("RSAs"), restricted stock units ("RSUs") and performance stock units ("PSUs") is included in selling, general and administrative expenses in the accompanying Consolidated Statements of Income and is comprised as follows (U.S. dollars in millions):



	Quarter ended
	March 30, 2018		March 31, 2017
Stock options	$	0.1	$	0.2
RSUs/PSUs	3.6		2.5
RSAs	1.0		0.9
Total	$	4.7	$	3.6

We received proceeds from the exercise of stock-based options of $0.7 million for the quarter ended March 30, 2018 and $0.1 million for the quarter ended March 31, 2017.

Stock Option Awards

Under the 2014 Plan and prior plans, 20% of the granted options vest immediately, and the remaining granted options vest in equal installments over the next four years. Options under the 2014 Plan and prior plans may be exercised over a period not in excess of 10 years from the date of the grant. Prior plan provisions are still applicable to outstanding options and awards under those plans. There were no stock option grants for the quarter ended March 30, 2018 or March 31, 2017.

The fair value for stock options was estimated at the date of grant using the Black-Scholes option pricing model, which requires us to make certain assumptions. Volatility is estimated based on the historical volatility of our stock over the past five years. The risk-free interest rate is based on U.S. Treasury zero-coupon issues with a remaining term equal to the expected term of grant. The dividend yield is estimated over the expected term based on our dividend policy, historical cash dividends and expected future

cash dividends. The expected term of grant was based on the contractual term of the stock option and expected employee exercise and post-vesting employment termination trends. Forfeitures are recognized as they occur.

Restricted Stock Awards

A share of restricted stock is one of our ordinary shares that has restrictions on transferability until certain vesting conditions are met.

For RSAs awarded under the 2014 Plan, 50% of each award of our restricted stock vested on the date it was granted. The remaining 50% of each award vests upon the six-month anniversary of the date on which the recipient ceases to serve as a member of our Board of Directors. Restricted stock awarded during the quarter ended March 30, 2018 and March 31, 2017 allow directors to retain all of their awards once they cease to serve as a member of our Board of Directors and is considered a nonsubstantive service condition in accordance with the guidance provided by the ASC on “Compensation – Stock Compensation.” Accordingly, we recognize compensation cost immediately for restricted stock awards granted to non-management members of the Board of Directors.

The following table lists RSAs awarded under the 2014 plan for the quarter ended March 30, 2018 and March 31, 2017:

Restricted Stock Units/Performance Stock Units

Under the 2014 Plan, each RSU/PSU represents a contingent right to receive one of our ordinary shares. The PSUs are subject to meeting minimum performance criteria set by the Compensation Committee of our Board of Directors. The actual number of shares the recipient receives is determined based on the results achieved versus performance goals. Those performance goals are based on exceeding a measure of our earnings. Depending on the results achieved, the actual number of shares that an award recipient receives at the end of the period may range from 0% to 100% of the award units granted. Provided such criteria are met, the PSUs will vest in three equal annual installments on each of the next three anniversary dates provided that the recipient remains employed with us. The RSUs will vest 20% on the award date and 20% on each of the next four anniversaries.

RSUs and PSUs do not have the voting rights of ordinary shares and the shares underlying the RSUs and PSUs are not considered issued and outstanding. However, shares underlying RSUs/PSUs are included in the calculation of diluted earnings per share to the extent the performance criteria are met, if any.

The fair market value for RSUs and PSUs is based on the closing price of our stock on the award date. Forfeitures are recognized as they occur.

The following table lists the various RSUs and PSUs awarded under the 2014 Plan for the quarter ended March 30, 2018 and March 31, 2017 (U.S. dollars in millions, except share and per share data):



Date of award	Type of award	Units awarded	Price per share
February 21, 2018	PSU	85,000	$	46.35
February 21, 2018	RSU	125,000	46.35
February 22, 2017	PSU	100,000	56.52
February 22, 2017	RSU	50,000	56.52

RSUs and PSUs are eligible to earn Dividend Equivalent Units ("DEUs") equal to the cash dividend paid to ordinary shareholders. DEUs are subject to the same performance and/or service conditions as the underlying RSUs and PSUs and are forfeitable.

We recognize expense related to RSUs and PSUs based on the fair market value, as determined on the date of award, ratably over the vesting period, provided the performance condition, if any, is probable.
