For all brokers / sell side advisors in the group: What is the benefit of engaging brokers /sell-sided advisors.

In particular, are the deal sourced from these are:

- Off-market / Sourcing: Are the deals exclusive to one broker/sell side advisor? I see similar deals listed on some online platforms which tells me they are heavily shopped and end up with the highest bidder.

- Due diligence: Do brokers/ sell side advisors perform additional due diligence on the companies they represent or they relay the message from the owner?
