What do I say about why I left my last job? after 17 years as an office manager

I have an interview next week and I am unsure how to explain why I left my last job as an office manager. It has been a long 3 weeks. I also do not want to seem like a risk. Do you mention numbers?

I keep it to two sentences: the company cut my team, and here is what I am proud of and what I am looking for next.
