Contractors prepare financials and Work-in-Process reports for analysis by banks, insurance and surety carriers, bond agents, regulators like the Small Business Administration (SBA) and other stakeholders. These audiences review the contractor’s financials to identify risks and determine eligibility for surety bonds and for financing. The Work in Process (WIP) report describes the financial performance and status of a contractor’s construction projects. Financial reviews of contractor's data today is labor-intensive, time-consuming, and costly.

Data Standards Streamline Processing and Reduce Costs

The XBRL data standard renders paper-based information computer-readable, reducing costs and delays. Bringing XBRL into the creation of the WIP report and supporting financials can render this data computer-readable and automatable, eliminating manual data entry. The XBRL data standard will not change the underwriting process or other analytics, it simply changes how the data is prepared and conveyed. The Small Business Administration (SBA) implemented an XBRL SBA Conversion application that automates the WIP process for bond agents as part of the SBA Surety Guarantee program.

For more on the business case, read the white paper Data Standards in Surety Underwriting and the NASBP article "XBRL Exec Explains How Uniform Data Standards Will Impact Bond Producers and their Interactions with Clients and Sureties".

How It Works

Contractors can create XBRL-formatted financials and WIP reports using tools mapped to the Work-in-Process (WIP) Taxonomy as shown below. Data users receiving financials in XBRL format can ingest the data automatically into their financial management systems after performing a one-time mapping that allows them to read the concepts reported.

Get Involved

The WIP Taxonomy is available as a Proposed Recommendation. Bonding agents, sureties, contractors, accounting firms and tool providers that serve the surety market should review the taxonomy, white paper and related materials.
