How to write about deals on resume

Fellow monkeys,
I have done an M&A internship in the past and am currently updating my resume. I have worked on several live transactions and would like to include them. How do you usually write about this on a resume?

At the moment, I have the following on there:
"$X - Xbn Buy-Side Advisory to an (Industry) Supplier" and the same with sell-side for a sponsor.
Below this main bullet, I list 1-2 sub-bullets with specific information on my involvement.

As it is not announced yet, I cannnot list specific names and also provide a relatively large range for the deal value (just to have at least some indication of the size).

Could you please let me know if this is appropriate or whether I should change the style/wording? Also, how do you handle talking in detail about unnanounced deals or deals that have closed but advisors have not been made public through official channels during interviews?

Many thanks in advance
