When the attorney makes a statement, how do I do the Examination Index?

When the depostition cancels and the attorney decides to just put a statement on the record, how do we make the Examination Index?

I can't put the witness' names, because there were three of them and I don't know which one was going to testify first.

Am I supposed to put the name of the attorney who gave the statement?

I would insert an exhibits index page if exhibit(s) were introduced and marked. All statements would be in colloquy. 

You might consider  this scenario for the  future. The examination is under way and then one of the attorneys decides to stop the deposition, for whatever reason, and places  a statement on the record.  That would be in colloquy as well as the response, if any, from other counsel.

It probably depends on what state you're in.  I leave the index page off  and go right into Proceedings and put the statement in colloquy.  If an attorney puts a statement on the record, it's generally one page.  In my mind, no index needed.  The purpose of an index is to find easily where things are in a depo transcript.

I don't put an index page in a Statement on the Record, nor do I put the stipulations page (not sure if you have them in your state).
