Change in number of years on the renewal of he vpn subscription

I received a reminder notice that the vpn would be renewed automatically, and also noticed that the number of years for the subscription has changed from 2 years to 1 year with the cost being a bit higher for one year compared to the 2 year cost.  Explain.
