Verify that, if the CDS spread for the example in Tables 25.1 to 25.4 is 100 basis points, the hazard rate must be $1.63 \%$ per year. How does the hazard rate change when the recovery rate is $20 \%$ instead of $40 \%$ ? Verify that your answer is consistent with the implied hazard rate being approximately proportional to $1 /(1-R)$, where $R$ is the recovery rate.
