Which one is correct for the SEC filing requirement?

Large accelerated filer, defined as a firm who has a public float of $700 million, should file form 10-K within 40 days from the fiscal year end.

The Division of Corporation Finance reviews 10-Q and 10-K when they are received. The staff may request additional information to company after the review, and the company should respond to each comment in a letter.

Since June, 2009, all public companies were required to use XBRL when they file 10-Q and 10-K. XBRL is a business reporting language which makes 10-L and 10-Q be more readable and accessable.
