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, the Company grants stock options to its employees, including the named executive officers. Each year, all current employees receive a stock option grant on the first business day of the year in recognition of their performance in the preceding year. In addition, all new hires receive a stock option grant on their date of hire. Employees who are promoted receive a stock option grant on the date of such employee’s promotion. 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 on July 1 of each year, respectively, pursuant to the Non-Employee Directors’ Stock Option Plan. In addition to regular, predetermined grants of stock options to employees as discussed above, non-employee directors receive option grants on the regular, predetermined grant dates pursuant to the Non-Employee Directors’ Stock Option Plan. The grants to employees and non-employee directors occur regardless of whether there is any material nonpublic information (“MNPI”) about the Company on such dates, and such grant dates are not specifically timed in relation to the Company’s disclosure of MNPI. The Company does not otherwise maintain any written policies on the timing of awards of stock options, stock appreciation rights, or similar instruments with option-like features. Furthermore, the Company has not timed the release of MNPI for the purpose of affecting the value of executive compensation. The following table is being provided pursuant to Item 402(x)(2) of Regulation S-K:
| Name |  |  | Grant Date |  |  | Number of securities underlying the award |  |  | Exercise price of the award ($/Sh) |  |  | Grant date fair value of the award |  |  | Percentage change in the closing market price of the securities underlying the award between the trading day ending immediately prior to the disclosure of MNPI and the trading day beginning immediately following the disclosure of MNPI |
