Software provider Lewtan redesigned its asset-backed securities surveillance site, ABSNet, to provide a clearer picture of the underlying collateral in trades made by investors. Lewtan created ABSNet as a source of data, analytics, software and content for the secondary market. It overhauled the system though to provide new features, which were created from lessons learned during the financial crisis, the company said. ABSNet now provides end-of-day bond pricing and a new search tool, Bond Screener, that allows users to identify pricing and credit risk dislocations in the market. To get this, it compares original and current data on bond performance, ratings and prices. Users can also customize alerts to track “trigger data” for residential mortgage-backed securities. “With the new and redesigned ABSNet website, Lewtan continues to expand the depth of structured finance information that market professionals demand in order to manage and monitor their global portfolio,” Lewtan CEO Ira Keller said. “Lewtan is committed to supporting market transparency, by providing the global securitization industry with the most comprehensive, up-to-date surveillance data and analytical tools.” Write to Jon Prior.
