Explaining a layoff without sounding bitter after 4 years as a bank teller

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?

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.
