Peter's Q is illustrating a point about "termination" of the service provider. While his hypothetical situation is not the usual understanding of that phrase, IMHO that section of Schedule C should not be omitted when there is only a one-year service agreement. Note this sentence in the instructions:
"Include a description of any material disputes or matters of disagreement concerning the termination, even if resolved prior to the termination."
Thus, the point of this item on the Schedule C is not to identify the service provider, but to identify problems or disagreements between the service provider and the plan sponsor.
The timing, as described by My2Cents, seems appropriate.
