That is a challenging question. I'll try to answer it in a couple of ways.
I think the department was more successful in implementing what you might call transactional obligations, one-off obligations--for example, making the payments, transferring most of the land, and implementing obligations that were one-time events. I think there was much more difficulty in implementing obligations that required long-term ongoing attention. That's probably the clearest distinction I can make between those that were implemented and those that weren't.
