We use locums throughout our system on many different occasions, and we fund those locums through vacancies and through other unexpended salary dollars. We have brought in some audiology staff to provide some locums. We have also had some incredible difficulty finding people to come in and provide some of that backfill for us. We went for an extended period of time last year where we were actually unable to find somebody to provide that backfill. So I think there are some challenges at a national level to find individuals, but, yes, we absolutely use some unexpended dollars to provide locums if and when we can find them.
