Extensible Business Reporting Language (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.
