Securities and Exchange Commission (SEC) Rule 12b-2 establishes the requirements a company must satisfy to be a large accelerated filer. It requires that the company has a public float of greater than $700 million, has been filing periodic reports for at least 12 months, has previously filed at least one annual report (e.g. Form 10-K), and is not a smaller reporting company. That is, a large accelerated filer is simply an accelerated filer whose public float exceeds $700 million.
Once a company satisfies the requirements of Rule 12b-2, then they have 60 days to file their Form 10-K and 40 days to file their Form 10-Q.
