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

I have an interview next week and I am unsure how to explain why I left my last job as an accountant. I also do not want to seem like a risk. Do you mention numbers?

Practise it out loud with a friend. Mine felt natural after the third try.

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.
