Why does the cash dividend notification reflect a rate of 0.00?

There may be times when the information relating to a cash dividend is incomplete. IBKR will deliver information on mandatory corporate actions to clients as we are made aware. At times, the information may be inaccurate or incomplete. Shareholders should review the information provided and compare this with public information available through company press releases or the Investor Relations Department of the company for verification purposes.
