What do I say about why I left my last job? after 18 years as a payroll clerk

I have an interview next week and I am unsure how to explain why I left my last job as a payroll clerk. There are 18 people counting on me, so I am trying to be careful. I do not want to blame the company. Do they ask follow-ups?

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.
