1,099 records have an AccountStatus with a potential invalid value. An additional 8,242 records have a missing AccountStatus.

Usually the AccountStatusDate is formatted as MM/DD/YYYY.

Account Status should not be used under any circumstance.

The highest valid value for AccountID is 100928473899 and no AccountID values will be higher than this in the future.

AccountStatusDate is ok to use because it is populated 95% of the time when AccountStatus is populated.
