Hi, the licence is perpetual so doesn't expire, the maintenance is valid for 1 year and is renewable. Maintenance includes access to the TechSmith certification, support and upgrade to new version.
Hope that helps,
I hope this will also help to explain what you are asking a little bit. You can also contact TechSmith Support or Pre-Sales Questions which is free to find out more or if you have more questions on this subject. Thanks for posting and have a great day/night.
