Explaining a layoff without sounding bitter - what worked for you?

I have an interview next week and I am unsure how to explain why I left my last job as an accountant. I have been practising in the mirror. 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.

Keep everything in writing and save the confirmation numbers. It saved me later.
