"The sales reported on this Form 4 were effected pursuant to a Rule 10b5-1 trading plan..."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

"Represents the weighted average sales price. The shares ... were sold in multiple transactions..."
restricted stock units ("RSUs") financial
"Includes 16,079 shares of Common Stock that will be issued ... upon vesting of restricted stock units ("RSUs")."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
