Where are the "Customer - Corporate Information - Special Instructions" stored?

Hello!

  I am a new admin for a Dynamics SL 2015 installation.  We are trying to gather the customer "special Instructions" for eventual migration to another ERP... and I cannot find where these live in the database.

  I would prefer something like a SQL table or query to look at, as I am well-versed in SQL.  I do not normally access the ERP yet; therefore, I am hesitant to look for an in-app solution both from my inexperience and because I might have to engage another's time multiple times before the project is over.
