"Proceeds from the sale were submitted to the Internal Revenue Service"

The Internal Revenue Service is the U.S. federal agency that administers and enforces tax laws, collects taxes, issues refunds, and provides official guidance on tax rules. For investors, its actions are important because tax assessments, audits, rule changes or interpretations can change a company’s after-tax profits, cash flow and legal risk—similar to how a referee’s calls and rulebook affect the outcome in a game.
