New license structure

I am trying to understand the new licensing and price structure for TestComplete. 

We have used TestComplete for 10+ years and have many fixed and floating licenses. We have always paid for maintenance on these licenses. Historically, the cost for annual maintenance on the products would be 20% of the cost of the product. If we paid $5000 for a fixed license then annual support would be $1000.

The new pricing on the smartbear website lists prices that are much cheaper than what we have paid in the past. It also now refers to the prices as a "subscription". 

So with this new pricing, what do you pay annually to renew the maintenance on your licenses? Is it still 20% or are these new prices annual amounts you must pay each year?
