The Plug

The plug in most pro-forma financial models, is usually one of the following items:

  1. cash and marketable securities (ensuring no negative balances),
  2. debt, or
  3. treasury stock, depending on how the firm finances itself.

After some further analysis, we use the ‘Cash / Sales’, and ‘Debt / Total asset’ ratios below. This leaves Treasury Stock (one component of Stockholder’s Equity) as the plug in the pro-forma model – meaning that new equity is either issued or re-purchased, in order to balance the accounts.
