There are several.
The first is that, in the construction of both the terms and conditions and the results...the work and results, that is the purpose of the contribution agreement, it's very clear what it's for and what it's not for and that the recipient would need to demonstrate that they are actually executing the work that was agreed to. If they don't execute the work that was agreed to, then in terms of the administration of the contribution payment, the funds that were committed wouldn't flow because there is an agreement about what they will do.
For example, if some entity didn't perform the required activities, then in terms of the review of the contribution agreement, we wouldn't make the payment. It does sometimes happen that, for whatever reason—sometimes it's for circumstances beyond the control of the recipient—they're unable to carry out the work that was committed to.
