Will I be charged while the EC2 is in stopping status?

Question

Recently one of my EC2 encountered a problem and becomes unavailable.  I stopped it and it takes about 1 hour to complete with a stopping status.  I'm wondering whether I will be charged the expense during this time period.

One more question, as this is the EC2 life cycle:
Start ACTION -> Health Check 1/2 In-progress -> Health Check 2/2 OK -> Running -> Stop ACTION -> Stopping -> Stopped.
What is the checkpoint regarding the expense charging?  From when to when?

Thank you!

The billing Period ends in the hour when the instance transitions into the stopping state. 
- enter stopping state at 55min you pay 1h
- enter stopping state at 65min you pay  2h

I'd like to note, since we launched per-second billing for EC2: https://aws.amazon.com/blogs/aws/new-per-second-billing-for-ec2-instances-and-ebs-volumes/ in the second example you are charged only for 1h 5min (instead of 2h) for instances to which per-second billing applies.
