I don't want to hear about how this is a great place to work. I just want the bottom line. How much does the job pay?
This might seem like a reference to the shape of ones pants, but it is not that interesting.
A reference to the standard accounting reports. These include the Income Statement, Balance Sheet, and Statement of Cash Flows.

In that sense the bottom line of each report is generally the most important indicator of the financial position. Anyone wanting the quick story would look first to the bottom line of each report.
