Financial Data and the Challenges for the Analytic Use Case Willi Brammertz, CTO ACTUS
Financial contracts • Financial contract: Central to the system • What is a financial contract? • Agreement between two (or more) Counterparties • To exchange cash flows • Following a set of rules • Only deterministic (factual) part of finance
Financial contract as a set of rules • Lawyers intention • Expressed esoterically • Different languages • Different expressions within language • Different expressions even within single bank • Nevertheless clear in intention and understandable • Can be substituted by computer algorithms • Substitution by algorithms is necessary condition for the analytic use case • The number of rules and their combination is limited (coverage 98+%) • One specific set of rules we call Contract Type (CT)

CT´s and master agreements • Master agreements define every aspect of financial contracts • Terms and their interpretations • Algorithms (e.g. interest calculations, option pay off…) • CT´s can be interpreted as • Set of global master agreements • Consistent master agreements across sectors
Data and algorithmsExample of interest calculation I • Creditor and debtor agree to exchange periodic interest payments • This cannot be expressed by data alone. We need • Data • Algorithms • Data • Interest rate • Principal and its evolution • Payment cycles • Day Count Methods, End of Months Conventions, Business Day Convention
Data and algorithmsExample of interest calculation II • The actual payment must be calculated using data and the algorithms • Interest payment algorithm needs • Cycle algorithm • EoM • BDC • Yearfraction calculation (DCM) • Principal algorithm • Etc.
What can we learn? • It´s not about data only. It´s about • DATA AND • ALGORITHMS • A financial contract needs both
An analogyDNA and gene expression DATA ALGORITHMS
DNACT DNA • DNA information • Gene expression • Context sensitive • Result: Protein, some other results • Important: Cells are autark in reproduction CT • Contract information • CT specific algorithm • Risk factor sensitive • Result: • State contingent cash flows • Analysis elements • Contracts must become autark in results production
Autark Financial ContractsSelf executing analysis Riskfactors ALGORITHMS DATA Basic Results
Consequence for XBRLOpen Questions • XBRL knows how to move data • Does XBRL know, how to move algorithms along? • What about the context? • Input: Risk factors • Output: Analysis results Riskfactors ALGORITHMS DATA Basic Results
