XBRL Filings

The following files have been filed with the U.S. Securities and Exchange Commission in XBRL. XBRL is an XML-based language for the Electronic transmission of business and financial data. XBRL is not an accounting standard; it is simply a standard for transmitting business and financial data.

The various XBRL exhibits included on this web page are displayed in their native XML format and have been included to provide you the option of importing them into your XBRL viewer of choice.

In 2018 the US Securities and Exchange Commission promulgated rules requiring the adoption of Inline XBRL.  As a Large accelerated filer that uses GAAP, Cogent made this adoption for all periods after June 15, 2019.  The new rule, once adopted by companies, eliminates the requirement for companies and funds to post “Interactive Data Files” (i.e., machine-readable computer code that presents information in XBRL format) on their websites.

The SEC rule adoption is announced here and here.

Cogent will maintain historical XBRL data already posted to its website (2011 to 2019) until September 30, 2020.
