On average, 1.5 percent of income payments need to be reversed because of incorrect incoming data. What if … Clearstream pays out a coupon incorrectly and client goes in default? issuer goes in default and Clearstream paid out, based on incorrect information? Settlement activity is collateralised, not income / corporate actions activity

Challenge: How to recuperate multi-million investment?

Are we legally covered in case of incorrect information? How do we charge data provisioning? Can we process incoming data STP? Since the core of our industry’s income is safekeeping fees based on market value, are we sure prices are correct for complex / illiquid securities? Can we outsource (part of) the data provisioning function?
