10-Q / 10-K

Think: 10K as short for Tanqueray...which is what you'll need after allllll the filings you'll do to complete the required 10K submission to the SEC if you're the CFO of a public company. The 10k is all the financial and metrical and legal crap that companies must submit to the government each year. For public companies, entire forests die, providing the pulp for the paper they're printed on. The 10-k is basically everything but the B.S. letter from the CEO to shareholders that's in the full Annual Report. Its sister report is the 10Q, as in "ten-q-very-much for doing this" four times a year, so there's less work at the end. So that's Q as in Quarterly. And K as in "Oh, Krap. Why didn't they name this 10A?"
