If someone I refer closes their Card Account or loses their referrals, do I lose their referrals too?

No, you will not lose any referrals in your Spending Squad if someone you refer loses their referrals.  If any Card Account in your Spending Squad is closed, then that Cardholder shall be removed from your Spending Squad and all of that Cardholder’s Direct Referrals and Indirect Referrals shall be moved one Generation closer to you. 

For example, if the Card Account of a Cardholder in your 4th Generation is closed, that Cardholder’s Direct Referrals shall be moved from your 5th Generation to your 4th Generation, the Indirect Referrals in that Cardholder’s 2nd and 3rd Generation (which previously were in your 6th and 7th Generation) shall be moved to your 5th and 6th Generation respectively.
