I'll take a run at your question, Ms. Falk, and then I'm going to pass it over to the clerk to fill in whatever I haven't comprehensively answered.
My understanding is that some of the challenges we have with respect to getting headsets to witnesses revolves around the amount of notice we give them before shipping a headset. Sometimes it can be laid at the feet of the witnesses. Sometimes it's just the logistics associated with not giving enough notice to make it happen.
Madam Clerk, do you care to correct or supplement what I've just said?
