19.	Long-term incentive compensation and shareholders’ equity

Long-term incentive compensation

Long-term incentive program (LTIP) compensation includes both stock-based awards (principally stock-settled stock appreciation rights, restricted stock units and performance stock units) as well as long-term performance-based cash awards. Long-term incentive compensation expense, which was primarily general and administrative in nature, was attributed to the Company’s U.S. dialysis and related lab services business, DMG business, corporate administrative support, and the ancillary services and strategic initiatives.

The Company’s stock-based compensation awards are measured at their estimated fair values on the date of grant if settled in shares or at their estimated fair values at the end of each reporting period if settled in cash. The value of stock-based awards so measured is recognized as compensation expense on a cumulative straight-line basis over the vesting terms of the awards, adjusted for expected forfeitures.

Stock-based compensation to be settled in shares is recorded to the Company’s shareholders’ equity, while stock-based compensation to be settled in cash is recorded to a liability. Shares issued upon exercise of stock awards have generally been issued from treasury shares.

Long-term incentive compensation plans

The Company’s 2011 Incentive Award Plan (the 2011 Plan) is the Company’s omnibus equity compensation plan and provides for grants of stock-based awards to employees, directors and other individuals providing services to the Company, except that incentive stock options may only be awarded to employees. The 2011 Plan authorizes the Company to award stock options, stock appreciation rights, restricted stock units, restricted stock, and other stock-based or performance-based awards, and is designed to enable the Company to grant equity and cash awards that qualify as performance-based compensation under Section 162(m) of the Internal Revenue Code. The 2011 Plan mandates a maximum award term of five years and stipulates that stock appreciation rights and stock options be granted with prices not less than fair market value on the date of grant. The 2011 Plan also requires that full value share awards such as restricted stock units reduce shares available under the 2011 Plan at a ratio of 3.5:1. The Company’s nonqualified stock appreciation rights and stock units awarded under the 2011 Plan generally vest over 36 to 48 months from the date of grant. At December 31, 2016, there were 7,337,266 stock-settled stock appreciation rights, 785,553 stock-settled stock units, 33,000 cash-settled stock appreciation rights and 1,600 cash-settled stock units outstanding, and 30,543,883 shares available for future grants, under the 2011 Plan.

A combined summary of the status of the Company’s stock-settled awards under the 2011 Plan, including base shares for stock-settled stock appreciation rights and stock-settled stock unit awards is as follows:

The Company granted 9,600 cash-settled stock-based awards during 2016. Liability-classified awards contributed $376, $(236) and $1,774 to stock-based compensation expense for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 the Company had 34,600 liability-classified stock-based awards outstanding, 5,000 of which were vested, and a total stock-based compensation liability balance of $124.

For the years ended December 31, 2016, 2015, and 2014, the aggregate intrinsic value of stock-based awards exercised was $73,001, $116,933 and $151,342, respectively. At December 31, 2016, the aggregate intrinsic value of stock awards outstanding was $79,717 and the aggregate intrinsic value of stock awards exercisable was $23,566.

Estimated fair value of stock-based compensation awards

The Company has estimated the grant-date fair value of stock-settled stock appreciation rights awards using the Black-Scholes-Merton valuation model and stock-settled stock unit awards at intrinsic value on the date of grant, except for portions of the Company’s performance stock unit awards for which a Monte Carlo simulation was used to estimate the grant-date fair value. The following assumptions were used in estimating these values and determining the related stock-based compensation attributable to the current period:

Expected term of the awards: The expected term of awards granted represents the period of time that they are expected to remain outstanding from the date of grant. The Company determines the expected term of its stock awards based on its historical experience with similar awards, considering the Company’s historical exercise and post-vesting termination patterns, and the terms expected by peer companies in near industries.

Expected volatility: Expected volatility represents the volatility anticipated over the expected term of the award. The Company determines the expected volatility for its awards based on the volatility of the price of its common stock over the most recent retrospective period commensurate with the expected term of the award, considering the volatility expectations implied by the market price of its exchange-traded options and the volatilities expected by peer companies in near industries.

Expected dividend yield: The Company has not paid dividends on its common stock and does not currently expect to pay dividends during the term of stock awards granted.

Risk-free interest rate: The Company bases the expected risk-free interest rate on the implied yield currently available on stripped interest coupons of U.S. Treasury issues with a remaining term equivalent to the expected term of the award.

A summary of the weighted average valuation inputs described above used for estimating the grant-date fair value of stock-settled stock appreciation rights awards granted in the periods indicated is as follows:

	Year ended December 31,
	2016			2015			2014
Expected term	4.2 years			4.1 years			4.2 years
Expected volatility		21.0	%		24.6	%		25.8	%
Expected dividend yield		0.0	%		0.0	%		0.0	%
Risk-free interest rate		1.0	%		1.5	%		1.5	%

The Company estimates expected forfeitures based upon historical experience with separate groups of employees that have exhibited similar forfeiture behavior in the past. Stock-based compensation expense is recorded only for awards that are expected to vest.

Employee stock purchase plan

The Employee Stock Purchase Plan entitles qualifying employees to purchase up to $25 of the Company’s common stock during each calendar year. The amounts used to purchase stock are accumulated through payroll withholdings or through optional lump sum payments made in advance of the first day of the purchase right period. This compensatory plan allows employees to purchase stock for the lesser of 100% of the fair market value on the first day of the purchase right period or 85% of the fair market value on the last day of the purchase right period. Purchase right periods begin on January 1 and July 1, and end on December 31. Contributions used to purchase the Company’s common stock under this plan for the 2016, 2015 and 2014 participation periods were $23,902, $24,523 and $19,010, respectively. Shares purchased pursuant to the plan’s 2016, 2015 and 2014 participation periods were 438,002, 413,859 and 297,954, respectively. At December 31, 2016, there were 7,484,395 shares remaining available for future grants under this plan, which includes an additional 7,500,000 shares approved by stockholders on June 20, 2016.

The fair value of employees’ purchase rights was estimated as of the beginning dates of the purchase right periods using the Black-Scholes-Merton valuation model with the following weighted average assumptions for purchase right periods in 2016, 2015 and 2014, respectively: expected volatility of 22%, 26% and 27%; risk-free interest rate of 0.8%, 0.2% and 0.2%, and no dividends. Using these assumptions, the weighted average estimated fair value of these purchase rights was $16.73, $18.76 and $16.40 for 2016, 2015 and 2014, respectively.

Long-term incentive compensation expense and proceeds

For the years ended December 31, 2016, 2015 and 2014, the Company recognized $73,337, $130,682 and $118,970, respectively, in total long-term incentive program (LTIP) expense, of which $38,338, $56,664 and $56,743, respectively, was stock-based compensation expense for stock appreciation rights, stock units and discounted employee stock plan purchases, which are primarily included in general and administrative expenses. The estimated tax benefits recorded for stock-based compensation in 2016, 2015 and 2014 were $12,731, $19,689 and $20,351, respectively. As of December 31, 2016, there was $92,987 total estimated unrecognized compensation cost for outstanding LTIP awards, including $59,016 related to stock-based compensation arrangements under the Company’s equity compensation and stock purchase plans. The Company expects to recognize the performance-based cash component of these LTIP costs over a weighted average remaining period of 1.0 year and the stock-based component of these LTIP costs over a weighted average remaining period of 1.4 years.

For the years ended December 31, 2016, 2015 and 2014, the Company received $28,397, $45,749 and $59,119, respectively, in actual tax benefits upon the exercise of stock awards. Since the Company issues stock-settled stock appreciation rights rather than stock options, it does not receive cash proceeds from stock option exercises.

Stock repurchases

During the years ended December 31, 2016 and 2015, the Company repurchased a total of 16,649,090 shares and 7,779,958 shares of its common stock for $1,072,377 and $575,380, or an average price of $64.41 and $73.96 per share, respectively, pursuant to previously announced authorizations by the Board of Directors. The Company has not repurchased any additional shares of its common stock from January 1, 2017 through February 24, 2017.

On July 13, 2016, the Company’s Board of Directors approved a share repurchase authorization in the amount of $1,240,748. This share repurchase authorization is in addition to the $259,252 remaining at that time under the Company’s Board of Directors’ prior share repurchase authorization announced in April 2015. As of December 31, 2016, there was $677,104 available under the current Board authorizations for additional share repurchases. Although these share repurchase authorizations have no expiration dates, the Company remains subject to share repurchase limitations under the terms of its senior secured credit facilities and the indentures governing its Senior Notes.

Charter documents & Delaware law

The Company’s charter documents include provisions that may deter hostile takeovers, delay or prevent changes of control or changes in management, or limit the ability of stockholders to approve transactions that they may otherwise determine to be in their best interests. These include provisions prohibiting stockholders from acting by written consent, requiring 90 days advance notice of stockholder proposals or nominations to the Board of Directors and granting the Board of Directors the authority to issue up to five million shares of preferred stock and to determine the rights and preferences of the preferred stock without the need for further stockholder approval.

The Company is also subject to Section 203 of the Delaware General Corporation Law which, subject to exceptions, would prohibit the Company from engaging in any business combinations with any interested stockholder, as defined in that section, for a period of three years following the date on which that stockholder became an interested stockholder. These restrictions may discourage, delay or prevent a change in the control of the Company.
