F6-Restriction of gift relief

Hi, I just listened the transfer of business asset and I think it is the first time I am satisfy with this chapter. Thank in advance for that. My question that: to be able to calculate the amount of gift relief restricted, the tax payer:
– should owns at leat 5% of the share is it Correct?
-Is this 5% is the same percentage we are talking about for tosatisfy the condition for 10% ER?
-What would happen for the calculation of the restriction if <5%? I guest here condition for ER are not fullfiled therefore no 10%ER

Thanks for your clarification in advance
