California Notice of Exchange Transaction is a document used to notify a party of a securities exchange transaction that has occurred in the state of California. This notice is required to be filed with the California Department of Business Oversight (DBO) and must include information regarding the securities exchanged, the parties involved, and the transaction date. There are two types of California Notice of Exchange Transaction: Form DBO-101 and Form DBO-102. Form DBO-101 is used when a security is being exchanged between two parties, while Form DBO-102 is used when the security is being exchanged between more than two parties. Both forms require the names of the parties involved, the amount of securities involved, the price of the securities, and the transaction date. Failure to file the California Notice of Exchange Transaction may result in fines or other penalties.
