The U.S. Commodity Futures Trading Commission fined ADM Investor Services $200,000 for rules violations Thursday.

The rules governed post-execution allocations, maintenance of books and records, and supervision of employees, the CFTC said in a news release. Post-execution allocation is a procedure where an account manager is permitted to bunch customer orders together for execution, and to allocate them to individual accounts at the end of the day.

ADM Investor Services is a Chicago-based registered futures commission merchant and a wholly owned subsidiary of the Archer Daniels Midland Company.
