MIR 3.6.3

The Regulator may authorise a Recognised Investment Exchange to provide for deferred publication of the details of transactions based on the size or type of the transaction. In particular, the Regulator may authorise the deferred publication in respect of transactions that:
(a) are large in scale compared with the normal market size for that Financial Instrument;
(b) are related to Financial Instrument traded on a trading venue for which there is not a liquid market; or
(c) are above a size specific to that Financial Instrument which would expose liquidity providers to undue risk and takes into account whether the relevant market participants are retail or wholesale investors.
