Context DRSUs represent the right to receive the economic value (typically shares) upon vesting and are commonly used for executive and officer compensation. Stock options will only convert to shares if exercised after vesting and subject to their exercise price and other plan terms (the filing does not disclose an exercise price). Grants like these are compensation-related and do not by themselves indicate the insider is buying or selling stock for investment purposes.
