Creating a custom column with a New word if date column is empty or null

Hi, Trying to manage data that is missing info.  I have one column that shows type of 'termintaed' or 'new hire'.  I have another column that shows 'acquired date' .  The column that shows acquired date is for existing employees of a new company that we bought so they are really not a new hire.  I want to take the column with the current terminated or new hire, and add a new option in the column of aquired, based on if there is date in the 'acquired date' field.  Its got dates, blanks and null in it.

The columns are all in the same table.  Do I do this in query editor or a dax measure or column in desktop?  And what would be the formula?
