Q. Regulation 87(2) of the Central Bank UCITS Regulations provides:

"Where the stock exchange value of the unit s of a UCITS ET F varies significantly from its net asset value, the responsible person shall ensure that an investor who has acquired:

(a) a unit, or

(b) where applicable, any right to acquire a unit that was granted by way of distributing a respective unit, on the secondary market, may sell the unit back to the UCITS ETF directly."

In what circumstances might this right to deal directly with the UCITS ETF arise?
