Earnings Per Common Share

 

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the period, adjusted for the potential dilutive effect of other securities if such securities were converted or exercised. The components of basic and diluted earnings per common share comprised the following (in millions, except per share amounts):

Calculated using the treasury stock method.

 

(2)

Certain stock options and warrants have been excluded from the computation of diluted earnings per share because their impact would be anti-dilutive for the three- and six-month periods ended June 30, 2017 and June 30, 2016. Additionally, certain convertible notes were excluded for the three- and six-month periods ended June 30, 2016. Under our convertible note hedge agreement, we were entitled to receive shares required to be issued to investors upon conversion of our Convertible Notes. Since related shares used to compute dilutive earnings per share would be anti-dilutive, they have been excluded from the calculation above.

 

Equity Incentive Plans

 

As of June 30, 2017, we have two shareholder-approved equity incentive plans: the United Therapeutics Corporation Amended and Restated Equity Incentive Plan (the 1999 Plan) and the United Therapeutics Corporation 2015 Stock Incentive Plan (the 2015 Plan). The 2015 Plan was approved by our shareholders in June 2015 and provides for the issuance of up to 6,150,000 shares of our common stock pursuant to awards granted under the 2015 Plan. The 2015 Plan is a broad-based stock incentive plan enabling us to grant stock options and other forms of equity compensation to our employees and non-employee directors. As a result of the approval of the 2015 Plan, no further awards will be granted under the 1999 Plan. During the six-month periods ended June 30, 2017 and June 30, 2016, we granted 1.9 million and 1.6 million stock options under the 2015 Plan, respectively.

 

Stock Options

 

We estimate the fair value of stock options using the Black-Scholes-Merton valuation model, which requires us to make certain assumptions that can materially impact the estimation of fair value and related compensation expense. The assumptions used to estimate fair value include the price of our common stock, the expected volatility of our common stock, the risk-free interest rate, the expected term of stock option awards and the expected dividend yield. As a result of the adoption of ASU 2016-09, we established an accounting policy election to account for forfeitures of share-based awards when they occur. Upon adoption, we recognized a cumulative-effect adjustment for the removal of the forfeiture estimate with respect to awards that were continuing to vest as of January 1, 2017. The adjustment resulted in a decrease to retained earnings of $0.4 million, which is net of a $0.2 million tax benefit. Refer to Note 2—Basis of Presentation—Recently Issued Accounting Standards.

 

In March 2017, we began issuing stock options with performance conditions under the 2015 Plan to certain executives. The awards have vesting conditions tied to the achievement of specified performance conditions. The performance conditions have target performance levels that span from one to three years. Upon the conclusion of the performance period, the performance level achieved will be measured and the ultimate number of shares that may vest will be determined. Share-based compensation expense for these awards is recorded ratably over their vesting period, depending on the specific terms of the award and achievement of the specified performance conditions. In total, we granted 0.9 million stock options with performance conditions with a total grant date fair value of $53.9 million based on achievement of target performance levels. We recorded $5.5 million in share-based compensation expense related to these awards for the six-month period ended June 30, 2017.

 

The table below includes the weighted-average assumptions used to measure the fair value of the stock options granted during the six-month periods ended June 30, 2017 and June 30, 2016:

These stock options have an aggregate grant date fair value of $109.3 million and $67.7 million, respectively.

As of June 30, 2017, unrecognized compensation cost was $124.8 million. Unvested outstanding stock options as of June 30, 2017 had a weighted average remaining vesting period of 2.8 years.

 

Restricted Stock Units

 

In June 2016, we began issuing restricted stock units under the 2015 Plan to our non-employee directors. Each restricted stock unit entitles the director to receive one share of our common stock upon vesting, subject to the director’s election to defer receipt of shares to a later date. We measure the fair value of restricted stock units using the stock price on the date of grant. Share-based compensation expense for the restricted stock units is recorded ratably over their one year vesting period. During the six months ended June 30, 2017, we granted 17,820 restricted stock units under the 2015 Plan with a weighted average grant date fair value of $132.30. The restricted stock units have an aggregate grant date fair value of $2.4 million. We recorded $1.0 million and $0.1 million in share-based compensation expense related to restricted stock units for the six-month periods ended June 30, 2017 and June 30, 2016, respectively. The share-based compensation expense related to restricted stock units granted is reflected in selling, general and administrative expense on our statements of operations.

 

As of June 30, 2017, unrecognized compensation cost related to the grant of restricted stock units was $2.3 million. Unvested outstanding restricted stock units as of June 30, 2017 had a weighted average remaining vesting period of one year.

 

Share Repurchase

 

In April 2017, our Board of Directors approved a share repurchase program authorizing up to $250.0 million in aggregate repurchases of our common stock (Repurchase Program). Pursuant to this authorization, in May 2017, we paid $250.0 million to enter into an accelerated share repurchase agreement (ASR) with Citibank, N.A. (Citibank). Under the ASR, we will repurchase a variable number of our shares subject to upper and lower stock price limits that establish the minimum and maximum number of shares that can be repurchased. The final number of shares we repurchase under the ASR will be determined based on the average of the daily volume weighted average price of our common stock over a specified period ending on the contract termination date. The ASR is scheduled to terminate during the fourth quarter of 2017; however, Citibank can accelerate termination of the agreement at its option. Pursuant to the terms of the ASR, in June 2017, Citibank delivered to us approximately 1.7 million shares of our common stock, representing the minimum number of shares we are entitled to receive under the ASR. Upon settlement of the ASR, we may receive additional shares of our common stock.
