Load Status on CN_COMM_LINES_API_ALL Table

Is there a document that describes what the load status values should be in the CN_COMM_LINES API_ALL table. 

I have an order line record in the cn_comm_lines_api_all. A process we ran raised a notification due to altered data. After running collections again a reversal transaction was created in the cn_comm_lines_api_all table. I have three lines for this sales order line in the cn_comm_lines_api_all table with a status of 'LOADED'. Two of these lines are 'OBSOLETE' in the CN_COMMISSION_HEADERS_ALL table (connecting using comm_lines_api_id).
