Tableau: calculated field after data is reshaped

I'm trying to wrap my head around how to created a calculated field in Tableau that is calculated after the source data is pivoted. My source data is "long" i.e. normalized and looks like this:

+---------+---------+-------+
| Company | Measure | Value |
+---------+---------+-------+
| A       | Sales   | 100   |
+---------+---------+-------+
| A       | Exp     | -10   |
+---------+---------+-------+
| B       | Sales   | 200   |
+---------+---------+-------+
| B       | Exp     | -30   |
+---------+---------+-------+

(Actually every company would have more than two records, but this is simplified)

What I'd like to get out is the following where Net is calculated as Sales + (2 * Exp). 

+---------+---------+-------+-------+
| Company | Sales   | Exp   | Net   |
+---------+---------+-------+-------+
| A       | 100     | -10   | 80    |
+---------+---------+-------+-------+
| B       | 200     | -30   | 140   |
+---------+---------+-------+-------+

I can get the following by simply having Company as my row and Measure as my column and then sum(Value):

+---------+---------+-------+
| Company | Sales   | Exp   | 
+---------+---------+-------+
| A       | 100     | -10   |
+---------+---------+-------+
| B       | 200     | -30   | 
+---------+---------+-------+

But how do I calculate an additional column based on the result of pivoting Measure?

Does this get you what you need?

The crux is creating calculated fields for Exp and Sales like this:

Exp = if [Measure] = "Exp" then [Value] end

Sales = if [Measure] = "Sales" then [Value] end

Those become measures you can use as the columns. enter image description here
