What do I say about why I left my last job? (update)

My whole team was cut and I want to say it calmly. This is my first time dealing with any of this. I have been practising in the mirror. What do you say?

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

Thanks for writing this out. I went through something close to it 11 months ago, and it settled down once I kept a simple log of every call and form.
