What is the definition of A Sensitivity Table?

In investment banking and private equity, sensitivity tables are used to assess the likely impact of changes in specific variables on the outcome of a merger, LBO or other corporate action. Some examples are:

• Merger Model - how is accretion/dilution affected?
• DCF Valuation - what happens if TV or discount rate change?
• LBO Model - how is IRR affected if leverage and/or purchase price changes?
