GlobalCredit; RWE

developer and consultant

at RWE, Essen. The aim of the project is to provide a platform for all companies within the RWE Group for unified credit risk exposure calculation and reporting for the portfolios of their wholesale customers. Open Link Endur serves as the central platform where contracts of all RWE Companies are held. Contracts and counterparty data are imported from the pre-systems on a daily basis within the end of day process. In the reporting process which is also part of the end of day process, exposures are calculated per creditrisk for all RWE companies and sent to a central reporting system. In addition to the reporting process an approval process for proposed deals is implemented. Here the deal importer constantly monitors the staging tables for new deal data and imports them. The business user then calculates exposures of these deals and sends them back to the pre-system. This is a time-critical process since the exposures serve as the basis of the decision whether or not a contract can be concluded. My fields of activity were among these: Deal Importer: Implementation of major parts of the deal importer, code review and bug fixes. Logic for Dealtranches: Deal tranches within the scope of a master agreement can be purchased at various times in the future. The master agreement contains a volume that is the allowance that may not be exceeded by the total of tranches booked. While the price of the master agreement is preliminary tranches substitute the price of the master agreement for their volume. This is achieved by the automated booking of counterdeals. Also tranche updates must be handled. Counterparty Importer: Implementation of major parts of the counterparty importer with support of dynamic name- and hierarchy changes. Credit Exposure Equivalent (CEE) calculation script: adjustments and extensions, e.g. implementation of APR (advanced purchase restriction) -logic. APR results in a decrease of the exposure. Results that are not within the scenario date plus a given time period must not be considered. This requires adjustments of simulation results. Settlement Exposure (SE) calculation script: script adjustments, code review, debugging and fixes. e.g. correction for closeout since the closeout period was not correctly considered in the original calculation. Code review, debugging and correction of scenario-splitting logic. Dynamic simulation splitting for CEE und SE calculations: With increasing number of deals the simulations started to crash more frequently due to a memory overflow. Thus, the total number of deals that is processed in a simulation had to be limited. With the constraint that all deals of a creditrisk have to be processed within the same simulation, the number of deals per creditrisk is evaluated and creditrisks are grouped for simulation splits in a way that the number of deals per simulation is evenly distributed for best performance. Concurrency control for writing calculation results to database tables: For load balancing, calculations are run in parallel tasks within the end of day process. When two processes try to write results into the same table simultaneously, data is lost since the Endur interface to Oracle does not support concurrency control. As a remedy I implemented a proprietary logic using a control table and a stored procedure. Miscellaneous tasks: Development of Maximum Exposure calculation script Development of Total Volumes Report RWE Deutschland Portfolio: Setup and testing for cross-company calculation workflow Development of market data import script: Prices, volatilities, correlations Marketmanager: Market curve, volatility and correlations setup. VaR Setup Service Manager: setup of end of day processing setup of products and pricebands Deal Exporter for successor project KITS Approval process "Pre Deal Limit Check" for proposed deals VPDLC - Volume based Pre Deal Limit Check setup. Marketcurve setup, product setup, sample deals setup, Scripts Support of the Live system, consulting with international business stakeholders and near-shore resources Monitoring of interfaces with SAP PI.
