Given interest rates flat 2%.
• Compute risky PV01 of initial the par CDS spread of 5% and 5 years time horizon.
• Assume current spread is 7%, Use the computed risky PV01 to verify that this is approximately riskyPV01*(S-S0)
• Consider a CDS at 5Y with par spread at 6%. Bootstrap the hazard rate between 5Yto 6Y to match the par CDS spread.
