Restricted Stock Unit financial
"The security title includes "Restricted Stock Unit" for two derivative transactions."
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
2023 Long-Term Incentive Plan financial
"RSUs are granted under the Tandem Diabetes Care, Inc. 2023 Long-Term Incentive Plan."
derivative security financial
"The transaction code description notes an "Exercise or conversion of derivative security"."
A derivative security is a financial contract whose value comes from the price or performance of something else, such as a stock, bond, commodity, or market index. For investors it acts like an insurance policy or a wager: it can be used to protect against losses, lock in prices, or amplify gains and losses, so it can change a portfolio’s risk and potential return without owning the underlying asset directly.
vesting financial
"RSUs "will vest on the one-year anniversary" of the grant date, per the footnote."
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
