Share Based Compensation [Abstract] |
Employee Benefit Plans | 11. Employee Benefit Plans As of June 30, 2018, the Company has the following share-based compensation plans: 2013 Equity Incentive Plan The 2013 Equity Incentive Plan (the “2013 Plan”) was approved by stockholders on November 20, 2013. The 2013 Plan replaced the 2005 Equity Incentive Plan (the “2005 Plan”). Under the 2013 Plan, the Company may grant stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units, and other share-based or cash-based awards to employees and consultants. The 2013 Plan also authorizes the grant of awards of stock options, stock appreciation rights, restricted stock and restricted stock units to non-employee members of the Board of Directors and deferred compensation awards to officers, directors and certain management or highly compensated employees. The 2013 Plan authorized the issuance of 9.0 million shares of the Company’s common stock. In addition, up to 12.7 million shares subject to stock options and awards available for issuance under the 2005 Plan may be transferred to the 2013 Stock Plan and would be added to the number of shares available for future grant under the 2013 Plan. The 2013 Plan includes provisions upon the granting of certain awards defined by the 2013 Plan as Full Value Awards in which the shares available for grant under the 2013 Plan are decremented 1.5 shares for each such award granted. Upon forfeiture or cancellation of unvested awards, the same ratio is applied in returning shares to the 2013 Plan for future issuance as was applied upon granting. During the fiscal years ended June 30, 2018 and 2017, an additional 9.0 million shares and 8.3 million shares, respectively, were authorized and made available for grant under the 2013 Plan. As of June 30, 2018, total options and awards to acquire 9.0 million shares were outstanding under the 2013 Plan and 12.1 million shares are available for grant under the 2013 Plan. Options granted under this plan have a contractual term of seven years. Enterasys 2013 Stock Plan Pursuant to the acquisition of Enterasys on October 31, 2013, the Company assumed the Enterasys 2013 Stock Plan (the “Enterasys Plan”). As of June 30, 2018, total options to acquire 0.8 million shares were outstanding under the Enterasys Plan. Options granted under this plan have a contractual term of seven years. No future grants may be made from the Enterasys Plan. 2005 Equity Incentive Plan The 2005 Plan was adopted by the Company’s Board of Directors on October 20, 2005, and approved by stockholders on December 2, 2005. The 2005 Plan replaced the Amended 1996 Stock Option Plan (the “1996 Plan”), the 2000 Non-statutory Stock Option Plan and the 2001 Non-statutory Stock Option Plan. The 2005 Plan includes provisions upon the granting of certain awards defined by the 2005 Plan as Full Value Awards in which the shares available for grant under the 2005 Plan are decremented 1.5 shares for each such award granted. Upon forfeiture or cancellation of unvested awards, the same ratio is applied in returning shares to the 2005 Plan for future issuance as was applied upon granting. Effective November 20, 2013, the 2005 Plan was replaced with the 2013 Plan, and, as of June 30, 2018, total options to acquire 0.2 million shares were outstanding under the 2005 Plan. No future grants may be made from the 2005 Plan, however, outstanding options and awards forfeited or canceled were allowed to be transferred to the 2013 Plan until December 2, 2015, at which time, no further shares may be transferred. A total of 6.6 million shares were transferred to the 2013 Plan. Shares Reserved for Issuance The following are shares reserved for issuance (in thousands):
|  | June 30, 2018 |  |  | June 30, 2017 |
Employee stock options and awards outstanding |  |  | 9,957 |  |  |  | 9,726 |

Stock Options The 1996 Plan was originally adopted in September 1996, and provided for the grant of options for common stock to eligible participants. Effective December 2, 2005, the 1996 Plan was terminated, and, as of June 30, 2016, no options to acquire shares remain outstanding under the 1996 Plan. No future grants may be made from the 1996 Plan. The following table summarizes stock option activity under all plans (shares and intrinsic value in thousands):
|  | Number of Shares |  |  | Weighted-Average Exercise Price Per Share |  |  | Weighted-Average Remaining Contractual Term (years) |  |  | Aggregate Intrinsic Value |
Options outstanding at June 30, 2017 |  |  | 3,062 |  |  | $ | 4.06 |  |  |  | 4.19 |  |  | $ | 15,868 |

Cancelled |  |  | (15 | ) |  | $ | 4.26 |  |  |  |  |  |  |  |  |
Options outstanding at June 30, 2018 |  |  | 2,193 |  |  | $ | 3.88 |  |  |  | 2.90 |  |  | $ | 8,996 |
Vested and expected to vest at June 30, 2018 |  |  | 2,193 |  |  | $ | 3.88 |  |  |  | 2.90 |  |  | $ | 8,996 |
Exercisable at June 30, 2018 |  |  | 1,980 |  |  | $ | 4.03 |  |  |  | 2.80 |  |  | $ | 7,781 |
The total intrinsic value of options exercised in fiscal years 2018, 2017 and 2016 was $6.3 million, $5.7 million and $0.2 million, respectively. There were no stock options granted in fiscal 2018 or 2017. The weighted-average estimated fair value of stock options granted in fiscal years 2016 was $1.59 per share. As of June 30, 2018, there was $0.2 million of total unrecognized compensation cost related to unvested stock options that will be fully recognized in fiscal 2019. Stock Awards Stock awards may be granted under the 2013 Plan on terms approved by the Compensation Committee of the Board of Directors. Stock awards generally provide for the issuance of restricted stock units (“RSUs”), including performance or market-based restricted stock units (“PSUs”) which vest over a fixed period of time or based upon the satisfaction of certain performance criteria. The Company recognizes compensation expense on the awards over the vesting period based on the award’s intrinsic value as of the date of grant. The following table summarizes stock award activity (shares and market value in thousands):
|  | Number of Shares |  |  | Weighted- Average Grant Date Fair Value |  |  | Aggregate Fair Market Value |
Non-vested stock awards outstanding at June 30, 2017 |  |  | 6,664 |  |  | $ | 4.66 |  |  |  |  |
Granted |  |  | 4,595 |  |  | $ | 11.15 |  |  |  |  |
Vested |  |  | (2,956 | ) |  | $ | 3.79 |  |  |  |  |
Cancelled |  |  | (539 | ) |  | $ | 8.05 |  |  |  |  |
Non-vested stock awards outstanding at June 30, 2018 |  |  | 7,764 |  |  | $ | 8.60 |  |  | $ | 61,804 |
The aggregate fair value, as of the respective vesting dates of RSUs vested during the fiscal years ended June 30, 2018, 2017 and 2016 was $51.2 million, $9.1 million and $8.6 million, respectively. Fiscal 2018 PSU During fiscal 2018, the Company approved the grant of 1.2 million stock awards to its vice president level employees or above (“VPs”), including 0.6 million stock awards to its Executive Officers. Fifty percent (50%) of the stock awards granted to the VPs, except the chief executive officer, were in the form of PSUs and fifty percent (50%) of the stock awards granted were in the form of service-based RSUs. The Company’s chief executive officer received sixty percent (60%) of his stock award grant in the form of PSUs, while forty percent (40%) of this award were in the form of RSUs. The RSUs vest from the original grant date as to one-third (1/3) on the one-year anniversary and one-twelfth (1/12) each quarter thereafter, subject to continued service to the Company. The PSUs referenced in the preceding paragraph will be considered earned once the Company’s U.S. GAAP earnings aggregates at least $0.32 per share over two consecutive quarters (the “2018 Performance Threshold”). Upon satisfying the 2018 Performance Threshold, the PSUs will vest with respect to the same number of RSUs that have vested which were granted on the same date and thereafter, will vest on the same schedule as the RSUs, subject to continued service to the Company. If the 2018 Performance Threshold is not met by the third anniversary of the grant date, the award is canceled. In addition, the 2018 Performance Threshold will be deemed satisfied upon the closing of a Change in Control (within the meaning of the Company’s 2013 Equity Incentive Plan) in the event the per share consideration received by the Company’s stockholders equals or exceeds $16.00 per share; or, in the event the consideration is less than $16.00 per share, the number of PSUs deemed to be earned will be determined by multiplying the number of PSUs by the ratio of the aggregate earnings per share of the last two quarters prior to the Change of Control to the $0.32 Performance Threshold. The grant date fair value per share of the PSUs referenced above was $10.90. During the year ended June 30, 2018, none of the PSU grants referenced above achieved their 2018 Performance Threshold. During fiscal 2018, the Company approved the grant of 0.1 million stock awards with market-based vesting criteria to certain VPs with grant date fair values per share ranging from $10.61 to $12.19 determined by using the Monte-Carlo simulation model. Fiscal 2017 PSU During fiscal 2017, the Company approved the grant of 1.5 million stock awards to its VPs, including 0.7 million stock awards to its Executive Officers. Fifty percent (50%) of the stock awards granted to the VPs were in the form of PSUs and fifty percent (50%) of the stock awards granted were in the form of RSUs. The RSUs vest from the original grant date as to one-third (1/3) on the one-year anniversary and one-twelfth (1/12) each quarter thereafter, subject to continued service to the Company. The PSUs referenced in the preceding paragraph were considered earned once the Company’s stock price equaled or exceeded $5.00 per share for 30 consecutive trading days after January 1, 2017 (the “2017 Performance Threshold”). The grant date fair values per share of the PSUs were determined by using the Monte-Carlo simulation model, ranging $3.02 to $3.09. The assumptions used in the Monte-Carlo simulation includes the expected volatility of 56%, risk-free rate of 0.9%, no expected divided yield, expected term of 3.0 years and possible future stock prices over the performance period based on historical stock and market prices. The assumptions used in the Monte-Carlo simulation includes the risk-free rate, expected divided yield, expected term, and possible future stock prices over the performance period based on historical stock and market prices. Once the 2017 Performance Threshold goal was attainted, the PSUs began to vest on the same schedule as the RSUs that were granted at the same time, subject to continued service to the Company. During the year ended June 30, 2017, all of the PSUs referenced above achieved their 2017 Performance Threshold and as such, began vesting and will be released on the schedule as noted, subject to continued service to the Company. During fiscal 2017, the Company approved grants of 1.4 million stock awards in the form of PSUs to certain VPs, including 0.9 million shares to its Executive Officers. Fifty percent (50%) of the PSUs are earned based on the Company’s stock price appreciation (the “Stock Price PSUs”) and fifty percent (50%) of the PSUs are earned based on the Company’s total stockholder return relative to the S&P Small Cap 600 Capped Information Technology Index (the “TSR PSUs”). The Stock Price PSUs represent the right to receive a number of shares of common stock up to one and one-third of the target number of Stock Price PSUs. They are earned and vest as follows based on the average adjusted closing stock price of the Company’s common stock for the 90 days ending as of May 4, 2020, subject to the grantees’ continued service through the certification of performance:
Average adjusted closing stock price |  | Shares earned
at least $8.96 but less than $11.63 |  | One-third
at least $11.63 but less than $13.15 |  | Two-thirds
at least $13.15 but less than $16.56 |  | 100%
$16.56 or more |  | One and one-third
No PSUs are earned if such average adjusted closing stock price is less than $8.96. The TSR PSUs represent the right to receive a number of shares of common stock up to 130% of the target number of TSR PSUs. They are earned and vest as follows based on the positive percentage point difference between the Company’s total stockholder return and the total stockholder return for the S&P Small Cap 600 Capped Information Technology Index over the performance period from May 4, 2017 to May 4, 2020, subject to the grantees’ continued service through the certification of performance:
Level |  | Percentage point difference between Company TSR and index TSR |  |  | Shares earned |
Threshold |  |  | 0 | % |  |  | 0 | %
Target |  |  | + 25 | % |  |  | 100 | %
Maximum |  |  | + 35 | % |  |  | 130 | %
Total stockholder return is calculated based on the 90-day average stock price at the beginning and end of the performance period. Linear interpolation is generally used to determine the number of shares earned for achievement between threshold and target levels and between target and maximum levels. However, if the Company’s total stockholder return over the performance period is negative, the number of shares earned will be capped at 100% of the target number of TSR PSUs. The grant date fair values per share of the Stock Price PSUs and the TSR PSUs were determined by using the Monte-Carlo simulation model, ranging $7.01 to $8.76, respectively. The assumptions used in the Monte-Carlo simulation includes the expected volatility of 54%, risk-free rate of 1.5%, no expected divided yield, expected term of 3.0 years and possible future stock prices over the performance period based on historical stock and market prices. For the fiscal years ended June 30, 2018, 2017 and 2016, the Company withheld an aggregate of 1.0 million shares, 0.4 million shares and 0.1 million shares, respectively, upon the vesting of RSUs, based upon the closing share price on the vesting date as settlement of the employees’ minimum statutory obligation for the applicable income and other employment taxes. For fiscal years 2018, 2017 and 2016, the Company remitted cash of $11.3 million, $2.0 million and $0.2 million, respectively, to the appropriate taxing authorities on behalf of the employees. The payment of the taxes by the Company reduced the number of shares that would have been issued on the vesting date and was recorded as a reduction of additional paid-in capital in the consolidated balance sheets and as a reduction of “Proceeds from issuance of common stock” in the financing activity within the consolidated statements of cash flows. As of June 30, 2018, there were $41.7 million in unrecognized compensation costs related to non-vested stock awards. This cost is expected to be recognized over a weighted-average period of 1.57 years Performance Grant Activity The following table summarizes PSU’s with market or performance based conditions granted and the number of awards that have satisfied the relevant market or performance criteria in each period (in thousands):
|  | Fiscal year 2018 |  |  | Fiscal year 2017 |  |  | Fiscal year 2016 |
Performance awards granted |  |  | 714 |  |  |  | 2,106 |  |  |  | 695 |
Performance awards earned |  |  | 566 |  |  |  | 839 |  |  |  | 582 |
2014 Employee Stock Purchase Plan In August 27, 2014, the Board of Directors approved the adoption of Extreme Network’s 2014 Employee Stock Purchase Plan (the “2014 ESPP”). On November 12, 2014, the stockholders approved the 2014 ESPP with the maximum number of shares of common stock that may be issued under the plan of 12.0 million shares. The 2014 ESPP replaced the 1999 Employee Stock Purchase Plan. The 2014 ESPP allows eligible employees to acquire shares of the Company’s common stock through periodic payroll deductions of up to 15% of total compensation, subject to the terms of the specific offering periods outstanding. Each purchase period has a maximum duration of six months. The price at which the common stock may be purchased is 85% of the lesser of the fair market value of the Company’s common stock on the first day of the applicable offering period or on the last day of the respective purchase period. During fiscal 2018, the 2014 ESPP had offerings periods of either 6 months or 24 months, commonly referred to as “look back periods”. As of June 30, 2018, there have been 6.6 million shares issued under the 2014 ESPP. Effective with the offering period beginning on February 1, 2016, the Company amended the 2014 ESPP to increase the maximum shares issuable for each purchase period from 1.0 million shares to 1.5 million shares. Effective with the offering period beginning on August 1, 2016, the Company amended the 2014 ESPP so that all future offering periods are limited to six months and to make certain other changes to the 2014 ESPP including adding new contribution limits for each offering period. Existing open offering periods prior to the effective date of the changes were unaffected by the amendments to the 2014 ESPP. Share Based Compensation Expense Share-based compensation expense recognized in the financial statements by line item caption is as follows (in thousands):
|  | Year Ended |
|  | June 30, 2018 |  |  | June 30, 2017 |  |  | June 30, 2016 |
Cost of product revenue |  | $ | 564 |  |  | $ | 333 |  |  | $ | 882 |
Cost of service revenue |  |  | 1,131 |  |  |  | 589 |  |  |  | 1,041 |
Research and development |  |  | 7,642 |  |  |  | 3,312 |  |  |  | 4,559 |
Sales and marketing |  |  | 9,843 |  |  |  | 4,253 |  |  |  | 4,633 |
General and administrative |  |  | 8,453 |  |  |  | 4,146 |  |  |  | 3,677 |
Total share-based compensation expense |  | $ | 27,633 |  |  | $ | 12,633 |  |  | $ | 14,792 |
The amount of stock based compensation expense capitalized in inventory has been immaterial for each of the periods presented. The Company uses the straight-line method for expense attribution other than the PSUs using the accelerated attribution method. Beginning in fiscal 2017, the Company no longer estimates forfeitures, but rather recognizes expense for those shares expected to vest and recognizes forfeitures when they occur. The Company’s estimated forfeiture rate in fiscal 2016 based on the Company’s historical forfeiture experience was 13% for non-executives and 19% for executives. The fair value of each stock option grant under the Company’s 2013 Plan and 2005 Plan is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of options granted is derived from historical data on employee exercise and post-vesting employment termination behavior. The risk-free rate is based upon the estimated life of the option and is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on a blended rate of the implied volatilities from traded options on the Company’s stock and historical volatility on the Company’s stock. The fair value of each share purchase option under the Company's 2014 ESPP is estimated on the date of grant using the Black-Scholes-Merton option valuation model with the weighted average assumptions noted in the following table. The expected term of the 2014 ESPP. The risk-free rate is based upon the estimated life and is based on the U.S. Treasury yield curve in effect at the time of grant. Expected volatility is based on the historical volatility on the Company’s stock. The weighted-average estimated per share fair value of shares purchased under the 2014 ESPP in fiscal years 2018, 2017 and 2016, was $3.25, $1.24 and $0.92, respectively.

401(k) Plan The Company provides a tax-qualified employee savings and retirement plan, commonly known as a 401(k) plan (the “Plan”), which covers the Company’s eligible employees. Pursuant to the Plan, employees may elect to reduce their current compensation up to the IRS annual contribution limit of $18,500 for calendar year 2018. Employees age 50 or over may elect to contribute an additional $6,000. The amount contributed to the Plan is on a pre-tax basis. The Company provides for discretionary matching contributions as determined by the Board of Directors for each calendar year. All matching contributions vest immediately. In addition, the Plan provides for discretionary contributions as determined by the Board of Directors each year. The program during fiscal 2018 is to match $0.50 for every Dollar contributed by the employee up to the first 2.5% of pay. The Company’s matching contributions to the Plan totaled $3.3 million, $1.4 million and $1.2 million, for fiscal years 2018, 2017 and 2016, respectively. No discretionary contributions were made in fiscal years 2018, 2017 or 2016.
