21. A group, endowed with juridical personality or not, is considered to have notice of a fact concerning a particular transaction from the time when the fact is brought to the attention of the individual conducting the transaction on behalf of the group or would have been brought to the attention of that individual if the group had exercised due diligence.
A group exercises due diligence if it maintains reasonable routines for communicating significant information about a transaction to the individuals conducting the transaction on its behalf and there is reasonable compliance with those routines. Due diligence does not require an individual acting on behalf of the group to communicate information unless that communication is part of the individual’s regular duties or the individual has reason to know of the transaction and that the transaction would be materially affected by the information.
