Award Timing Disclosures [Line Items] |  |
Award Timing MNPI Disclosure | Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information ​ From time to time, we have granted stock options to our employees, including the named executive officers. Historically, we granted new-hire option awards on or soon after a new hire’s employment start date and annual refresh employee option grants in the first quarter of each fiscal year, which refresh grants were approved by the Compensation Committee prior to the grant date. Also, non-employee directors receive automatic grants of initial and annual equity awards, at the time of a director’s initial appointment or election to the board and at the time of each annual meeting of our stockholders, respectively, pursuant to the Non-Employee Director Compensation Policy, as further described under the heading, “Director Compensation” above. We do not otherwise maintain any written policies on the timing of awards of stock options, stock appreciation rights, or similar instruments with option-like features. The Compensation Committee considers whether there is any material nonpublic information, or MNPI, about our company when determining the timing of stock option grants and does not seek to time the award of stock options in relation to our company’s public disclosure of MNPI. We have not timed the release of MNPI for the purpose of affecting the value of executive compensation. The following table sets forth information relating to the grant of stock options close in time to the filing of certain SEC reports.
