Your Debt Coverage Ratio is calculated here. It takes into account any additional bonding and revenue you've added to your program.

If you make any changes to figures in the "Bonding" section that cause this ratio to drop below the Minimum Debt Coverage Ratio you established above, the words "Low Coverage Ratio!" will appear in the "Debt Coverage Ratio" line below.

In that case, you can 1. decrease your bonding, 2. increase your revenues or 3. decrease your "Minimum Debt Coverage Ratio.
