Award Timing Disclosures [Line Items]

From time to time, we grant equity awards, including stock options, to our employees, including our named executive officers. Historically,we have typically granted new-hire option awards on, or within the calendar quarter of, a new hire's employment start date and annual refresh employee option grants in the first quarter of each fiscal year, which refresh grants are typically approved at a regularly scheduled meeting of the Compensation Committee occurring in such quarter. Also, non-employee directors receive automatic grants of initial and annual stock option 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 our non-employee director compensation policy, as further described under the heading, “Director Compensation—Non-Employee Director Compensation Policy” below. 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 (“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 public disclosure of MNPI. We have not timed the release of MNPI for the purpose of affecting the value of executive compensation.
