I stand corrected. With my company and experiences, my company made the reservations utilizing a corporate rate, but we, individually, were responsible for room payment, not to a master bill...my bad.
This is from HH T&C:

12. A Member whose individual hotel bill is billed directly to a company and the Member is responsible for authorization for settlement at check-out is eligible for HHonors points as described above in item number 4 under "Accrual of Points". However, group master-billing arrangements where charges for multiple rooms are placed on one hotel bill and billed to a company or common address or settled at check-out by one individual are not eligible. Incidental charges (those charged to a Member's room) paid for directly by the Member at check-out are eligible for point credit. Incidental charges billed to a master bill are not eligible for point credit.
