Max out Date calculation for L1


I came to US on 30-OCT-2010 and stayed in US until 1-JUN-2013 on L1B VISA.

Again after 3 years and 4 months , I came back to US on L1A on 16-JUN-2016 and Currently staying here in US

So my question here is ’ How does Max out date will be calculated for my case ? using both L1B & L1A ?
please advise based on above mention dates …what will be max out date for me ?
