(SILICON BEAT) — Today, Groupon filed a series of letters exchanged with the U.S. Securities and Exchange Commission in which the agency continued to raise questions about the daily deal site’s accounting and disclosures.

The letters from the SEC can be found here. Groupon’s responses are here.

The letters are actually dated from August through October this year. And they refer to issues raised in Groupon’s 2011 1o-K and it’s first quarter 10-Q. Such documents are typically not disclosed by companies until several weeks after they are exchanged.

No action was ultimately taken. Groupon did agree to revise some disclosures.
