Workiva Leads Global Adoption of Inline XBRL

Wdesk Used to File More Than 84% of All Inline XBRL facts with the
SEC in Q4 2017;

Wdesk Among First to Incorporate ESEF
Taxonomy for European Filers

(NYSE:WK), a leading provider of solutions for enterprise productivity,
today announced Wdesk users filed more than 84 percent of all Inline
XBRL facts with the U.S. Securities and Exchange Commission (SEC) in the
fourth quarter of 2017. Wdesk has also been used to file more than 69
percent of all Inline XBRL filings.

XBRL (eXtensible Business Reporting Language)
, also known as iXBRL,
creates a single, standardized, machine-readable report that is
integrated within companies’ human-readable HTML filings. Inline XBRL
combines the advantages of both filing types into a single,
browser-friendly document.

“XBRL was arguably the biggest thing to come along to enable machine
readable financial data, and Inline XBRL is how we advance toward the
common goal of providing better data,” said Marty Vanderploeg, President
and Chief Operating Officer of Workiva. “Workiva is committed to
improving data quality, increasing efficiencies and easing regulatory
burdens for our customers.”

Wdesk was used to create the
first Inline XBRL filing
less than three weeks after the SEC began
allowing the voluntary format in the U.S. in June 2016. Nine months
later, in March 2017, the SEC voted to propose
amendments to require Inline XBRL in filings submitted by public
companies and mutual funds that currently file with XBRL
. If
approved, the amendment could require corporate financial statements and
mutual fund risk/return summaries to be filed in Inline XBRL sometime in

“The SEC’s proposal shows the Commission’s long-term commitment to
structured data by using Inline XBRL to improve data quality and
accessibility,” said Vanderploeg. “With Wdesk, our customers have
built-in transparency and the tools they need to meet the impending
regulatory changes.”

European Securities and Markets Authority Selects Workiva to
Incorporate ESEF Taxonomy

Workiva’s strong leadership in Inline XBRL in the U.S. was one reason
why the European Securities and Markets Authority (ESMA) selected the
Wdesk platform to be among the first solutions to successfully
incorporate and test ESMA’s
European Single Electronic Format (ESEF) taxonomy
. Inline XBRL will
be required under ESEF for more than 5,000 EU issuers for their annual
financial report, ending on or after January 1, 2020.

“It made sense for Workiva to be among the first to demonstrate Inline
XBRL to streamline ESEF requirements,” said Vanderploeg. “Workiva
has been on the forefront of helping Foreign Private Issuers use XBRL
tags in their SEC filings
, and we are among the first companies to
be certified
by XBRL International

“Regardless of pending regulations, filers need future-proof technology
to manage risk, establish disclosure procedures and focus on data
quality,” added Vanderploeg. “Our Wdesk customers are able to
collaborate in a secure, integrated environment with full transparency,
which helps drive better business and investment decisions.”
