Note that from last year there are no more number of subsidiary based billing, you can have upto 125 subs in one country. Though there is one caveat, NS now charges by country+currency combination ie if you have two subs in one country but different currency then it would be counted as separate country. This is kind of stupid, they are showing that they have lowered the cost by removing per sub fee but sneaked in this extra charges. Which I learned last Friday when I tried to reactivate one of my old subs. What a bummer.
