Incidentally, I've heard something similar to what Kritchlow is talking about although I can't find a reference for it. About 5 years ago my old company got on us about aborted takeoffs and it created a stir on the line. We needed to submit a report anytime we aborted a takeoff for any reason. The reason given was that any time we take the runway for the purpose of flight, then subsequently exit the runway, the FAA would be notified by ATC. Therefore we better have a report 'in the system' on our end when such a thing happens. There was also some tribal knowledge that one exception was if the abort was because an FA or passenger wasn't seated, so guys would tell ATC that it was passenger/FA related regardless of the cause just to avoid any paperwork. This was all long enough ago that I have no idea how much of it was legit or just line pilot gossip BS.
Looking at my current company's manual, I only have a report to write if I do a high speed abort. That and a logbook entry. It doesn't say anything else about it.
