Case Study: MidWestOne Bank cuts SEC reporting time by 10 days and simplifies XBRL tagging with Workiva

MidWestOne Bank - Customer Case Study

MidWestOne Financial Group, a $1.6 billion Iowa-based financial holding company with 25 bank locations and an insurance arm, relied on a single SEC reporting officer to assemble, review and file complex reports using word processing files, spreadsheets and a third‑party printer. That manual process was time-consuming, error‑prone and inflexible—especially with new XBRL tagging requirements looming—which meant long hours, rushed reviews and late changes that took overnight to process.

In May 2010 MidWestOne adopted Workiva’s cloud‑based Wdesk for external reporting, gaining integrated document linking, roll‑forward templates and built‑in XBRL support. The intuitive platform let the reporting officer file 10‑Qs and 8‑Ks far faster, cut up to 10 days from the reporting cycle, reduced late nights and produced more accurate, polished filings while keeping control of the XBRL tagging process.
