Stock-based Compensation and Stock Plans
Stock-based Compensation and Stock Plans.
The Company expenses all stock-based payments to employees and non-employee distributors, including stock options, leveraged share awards and restricted stock units or (“RSUs”), based on the grant date fair value over the required award service period using the graded vesting attribution method. As the Company’s common stock is not currently traded on a national securities exchange, the fair market value of the Company’s common shares is determined by the Compensation Committee. For awards with a performance vesting condition, the Company recognizes expense when the performance condition is considered probable to occur. Stock-based compensation expense recognized was $5.5 million and $5.8 million for the three months ended February 28, 2014 and 2013, respectively, and $14.7 million and $32.3 million for the nine months ended February 28, 2014 and 2013, respectively. The decrease in the expense was related to the fiscal year 2013 modification that is described below.
On July 2, 2012, LVB launched a tender offer to eligible employees to exchange all of the stock options and RSUs held by such employees for new stock options and RSUs. Following the expiration of the tender offer on July 30, 2012, LVB accepted for exchange eligible options to purchase an aggregate of 29,821,500 shares of common stock of LVB and eligible RSUs underlying an aggregate of 3,665,000 shares of common stock of LVB. In accordance with the terms and conditions of the tender offer, on July 31, 2012, LVB granted 29,821,500 new options and 10,795,000 new RSUs in exchange for the cancellation of such tendered options and RSUs.
The objective of the tender offer was to provide employees who elected to participate with new options and new RSUs, the terms of which preserve the original incentive effect of the Company’s equity incentive programs in light of market and industry-wide economic conditions. The terms of the new stock options differed in respect to the tendered options principally with respect to:
•
Exercise Price—The exercise price for the new stock options was lowered to the then current fair value of $7.88 per share.
•
Vesting Periods—All prior options that were vested as of the completion date of the tender offer remain vested. All time-vesting options which were unvested as of the completion date of the tender offer will continue to vest on the same schedule on which they were originally granted. All unvested replacement extended time vesting options and modified performance options will vest on a schedule which is generally two years longer than the original vesting schedule, but in no case past 2017.
•
Performance Vesting Threshold—The new modified performance options will vest over the new vesting period if, as of the end of the Company’s most recent fiscal year ending on or prior to such vesting date, Biomet, Inc. has achieved the EBITDA target for such fiscal year determined by the Compensation Committee of the Board of Directors of the Company on or before the ninetieth (90th) day of such fiscal year and consistent with the Company’s business plan.
The terms of the new RSUs are different from the tendered RSUs with respect to the vesting schedule, performance conditions and settlement. The new RSUs are granted subject to either a time-based vesting or a performance-based vesting requirement. Unlike the exchanged RSUs, the new RSUs do not vest in full on May 31, 2016 regardless of satisfaction of the vesting conditions. In addition, following the termination of employment with the Company, new RSUs, whether vested or unvested, will be forfeited if such employee provides services to any competitor of the Company. In addition, participants holding new RSUs received new awards called management dividend awards representing the right to receive a cash payment. Management dividend awards vest on a one-to-one basis with each new time-based RSU. Vested management dividend awards are paid by cash distributions promptly following each anniversary of the grant date until the earlier of an initial public offering of the Company or the fifth anniversary of the grant date, subject to withholding taxes. Upon termination of employment for any reason, management dividend awards will be forfeited. The new RSUs were granted under the Company’s 2012 Restricted Stock Unit Plan, which was adopted by LVB on July 31, 2012. The maximum number of shares of common stock, par value $0.01 per share, that may be issued under the Company’s 2012 Restricted Stock Unit Plan is 14,000,000, subject to adjustment as described in the Plan. The management dividend awards are accounted for as liabilities.

On March 27, 2013, the Compensation Committee of LVB approved and adopted an amended LVB Acquisition, Inc. 2012 Restricted Stock Unit Plan. The amendment permits certain participants in the Plan to be eligible to elect to receive a cash award with respect to their vested time-based RSUs subject to certain conditions, including the satisfaction of certain Company performance thresholds with respect to Adjusted EBITDA and unlevered free cash flow. To the extent the Company performance conditions have been satisfied for the applicable fiscal year, eligible participants will be entitled to elect to receive a cash award based on the fair market value of the Parent’s common stock on the first day of the applicable election period, payable in three installments over a two-year period, with respect to their vested time-based RSUs and such vested time-based RSU will be forfeited upon such election. Payment of the cash award is subject to the participants’ continued employment through the payment date (other than with respect to a termination by the Company without cause).
During the second quarter of fiscal year 2013, the distributor options totaling 3,193,167 were modified to lower the exercise price to the then-current fair value of $7.88 per share.
