Rule 12b-2 adds three conditions beyond the float range. The company must have been subject to reporting under Section 13(a) or 15(d) of the Exchange Act for at least twelve calendar months, must have filed at least one annual report, and must not be eligible for smaller reporting company treatment under that definition's revenue test. The last condition means a company with modest revenues can hold a float above $75 million and still be a non-accelerated filer. Status is set once a year, at fiscal year end.
The deadlines follow from the label. Form 10-K's General Instruction A gives an accelerated filer 75 days after fiscal year end, fifteen days more than a large accelerated filer and fifteen fewer than a non-accelerated filer. Form 10-Q gives it 40 days after quarter end, the same as a large accelerated filer. Accelerated filers are also among the companies that must disclose unresolved SEC staff comments in Item 1B of the 10-K.
Leaving the category requires falling below $60 million in float, or qualifying as a smaller reporting company under the revenue test. Either one moves the company to non-accelerated status, and it cannot return until it again meets the original entry conditions. For investors, the status is a quick read on size and a signal of when the next report is due.
