what Paragon does

Paragon is a fixed income portfolio accounting solution, processing bonds and money market instruments based on three primary business functions: trade capture, processing and reporting

Accounting and position-keeping platforms help banks manage their exposures on a day-to-day basis. When it comes to reporting concise information to executive board members and stakeholders, however, old style paper reports are generally not only dull in presentation style but often lack graphics to provide clarity and reflect notable changes or exceptions.

Paragon offers inventory, cash flow, maturity and management reports that are enriched with visually appealing graphics. This will provide greater insight to all stakeholders and inform decision makers based on data extracted directly from Paragon’s records. This step will avoid the potential errors that can occur if information needs to be manipulated or augmented before being delivered to interested parties.

Paragon has a proud track record of serving a diverse range of financial services organisations – from small community or regional banks to several of the leading US banks. The solution also supports credit unions, fixed income broker-dealers and correspondent banks that provide third party administration services to banking clients.

Paragon is proven over many years to be excellent at handling the full range of complex variable rate instruments with ease:

  • Mortgage backed securities
  • Asset-backed securities
  • Debentures
  • Treasury securities
  • Other fixed-income instruments
