How do I explain a layoff in interviews? after 12 years as a sales associate

They always ask why I left, and I freeze. I have read a lot of threads here and could not find my exact situation. 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.

If a company has been in the news for layoffs, you can mention that. Often the interviewer already knows.
