Regulation FD regulatory
"Item 7.01 | Regulation FD Disclosure On April 7, 2026, we announced..."
Regulation FD is a rule that prevents company insiders, like executives, from sharing important information with some people before others get it. It matters because it helps ensure all investors have equal access to key news, making the stock market fairer and reducing chances of insider trading.
Inline XBRL regulatory
"104 | Cover Page Interactive Data File (embedded within the Inline XBRL document)."
Inline XBRL is a file format for financial filings that embeds machine-readable data tags directly inside the human-readable report, so the same document can be read by people and parsed by software. For investors it makes extracting, comparing and verifying financial numbers faster and more reliable—like a grocery list where each item also has a barcode—reducing manual errors and speeding up analysis.
