(11) Stockholders’ Equity

Common Stock. On February 21, 2014, our board of directors approved a new share repurchase program, authorizing us to acquire up to an aggregate of 20.0 million shares of our common stock. The program allows us to repurchase shares of our common stock from time to time for cash in the open market, or in negotiated or block transactions, as market and business conditions warrant and subject to applicable legal requirements. The 20.0 million shares the new program authorizes us to purchase are in addition to the shares we repurchased on or before February 21, 2014 under our previous programs. There is no expiration date for this program, and the program may be accelerated, suspended, delayed or discontinued at any time at the discretion of our board of directors. All share repurchases since February 21, 2014 have been executed in accordance with this program.

During fiscal year 2018, we repurchased 550,000 shares at a cost of $53.8 million and during fiscal year 2017, we did not purchase any shares under our share repurchase program. As of June 30, 2018, we have repurchased a total of 41.6 million shares at a cost of $1.6 billion. Shares that are repurchased are classified as “treasury stock pending future use” and reduce the number of shares outstanding used in calculating earnings per share. At June 30, 2018, 13.1 million additional shares can be repurchased under the approved share repurchase program.

Preferred Stock. In April 1997, our board of directors authorized 2,000,000 shares of $0.01 par value preferred stock. No such shares were issued or outstanding at June 30, 2018.

Stock Options and Restricted Stock Units. We have granted stock options and restricted stock units to personnel, including officers and directors, in accordance with the ResMed Inc. 2009 Incentive Award Plan (the “2009 Plan”). These options and restricted stock units vest over one to four years and the options have expiration dates of seven years from the date of grant. We have granted the options with an exercise price equal to the market value as determined at the date of grant.

At the annual meeting of our stockholders in November 2017, our stockholders approved an amendment and restatement to the 2009 Plan to increase the number of shares of common stock that may be issued or transferred pursuant to awards under the 2009 Plan by 7.4 million. The amendment and restatement imposes a maximum award amount which may be granted under the 2009 Plan to non-employee director in a calendar year, which when taken together with any other cash fees earned for services as a non-employee director during the calendar year, has a total value of $0.7 million, or $1.2 million in the case of a non-employee director who is also serving as chairman of our board of directors. The amendment and restatement also increased the maximum amount payable pursuant to cash-denominated performance awards granted in any calendar year from $3.0 million to $5.0 million. In addition, the amendment and restatement extended the existing prohibition on the payment of dividends or dividend equivalents on unvested awards to apply to all awards, including time-based restricted stock, deferred stock and stock payment. The term of the 2009 Plan was extended by four years so that the plan expires on September 11, 2027.

The maximum number of shares of our common stock authorized for issuance under the 2009 Plan is 51.1 million. The number of securities remaining available for future issuance under the 2009 Plan at June 30, 2018 is 17.8 million. The number of shares of our common stock available for issuance under the 2009 Plan will be reduced by (i) 2.8 shares for each one share of common stock delivered in settlement of any “full-value award,” which is any award other than a stock option, stock appreciation right or other award for which the holder pays the intrinsic value and (ii) one share for each share of common stock delivered in settlement of all other awards. The maximum number of shares, which may be subject to awards granted under the 2009 Plan to any individual during any calendar year, may not exceed 3 million shares of our common stock (except in a participant’s initial year of hiring up to 4.5 million shares of our common stock may be granted).

At June 30, 2018, there was $75.3 million in unrecognized compensation costs related to unvested stock-based compensation arrangements. This is expected to be recognized over a weighted average period of 2.2 years. The aggregate intrinsic value of the stock-based compensation arrangements outstanding and exercisable at June 30, 2018 and June 30, 2017 was $222.3 million and $194.5 million, respectively. The aggregate intrinsic value of the options exercised during the fiscal years 2018, 2017 and 2016, was $27.5 million, $28.1 million and $40.4 million, respectively.

Employee Stock Purchase Plan (the “ESPP”). Under the ESPP, we offer participants the right to purchase shares of our common stock at a discount during successive offering periods. Each offering period under the ESPP will be for a period of time determined by the board of directors’ compensation committee of no less than 3 months and no more than 27 months. The purchase price for our common stock under the ESPP will be the lower of 85% of the fair market value of our common stock on the date of grant or 85% of the fair market value of our common stock on the date of purchase. An individual participant cannot subscribe for more than $25,000 in common stock during any calendar year. At June 30, 2018, the number of shares remaining available for future issuance under the ESPP is 0.5 million shares.

During years ended June 30, 2018 and June 30, 2017, we issued 302,000 and 327,000 shares to our employees in two offerings and we recognized $5.2 million and $4.2 million, respectively, of stock compensation expense associated with the ESPP.
