# DR util component

The `drb2b_drUtil` is a component with no UI. This component reloads the `drb2b_addressDetails`, `drb2b_checkoutSummary`, `drb2b_drCompliance` components and get the latest values. When you load this component, it triggers an event (`CALCULATE_TAX`) to reload the `drb2b_addressDetails`, `drb2b_checkoutSummary`, `drb2b_drCompliance` components.
