More from T3's SEC filings (SEC.gov).
T3 loses money year after year. Their own filings show their company (Class A represents their ownership's capital) lost money in 2010, 2011 and 2012. (They did not post a breakdown of earnings by member classes for 2013.)
http://www.sec.gov/Archives/edgar/vprr/13/9999999997-13-001763 (page 8 of the PDF, which is page 4 printed on the document due to the cover letter).
In 2012, the most recent year they show the breakdown of losses by member class, T3 lost over 30% of the amount of their company's capital base as of the end of that year. (Finished 2012 with $670,000 of Class A loss, and they left the year with only $1,931,000.) Looking at their previous years, this seems to be a pattern, not an anomaly.
The $10 million total capital (versus only $1.93 million of their own) on 12.31.2012 shows they are highly leveraged and running the firm mostly off trader and group leader capital contributions (5 times leveraged by using Class B and C capital contributions).
"T3 loses money year after year." Sgt. Slotter seems to dig deep into specifics, so let's add a few:
In 2010, T3 reported members' equity of $1.2 million.
In 2011, that number rose to $9.1 million.
In 2012, the number rose yet again, to just over $10 million.
And in 2013, the last year of publicly available filings, yep, it rose, AGAIN, to $14.8 million.
It was already posted that as a "Class C" member, your losses are capped by your capital contribution. In other words, if you put up $5k, then you are not liable for losses beyond that 5k. If for any reason a Class C trader "blows up" beyond their capital contribution, then the losses are absorbed by either the Class B or Class A members.
Fortunately, Class C traders have made money! Specifically...
In 2010, they made just over $63,000.
In 2011, they made $3.3 million.
In 2012, they made around $3 million.
As you correctly stated, the breakdown of members is not listed in the 2013 filings. However, it's quite possible that they made money in 2013 as well, given that the members' equity base has increased in each year since 2010.
Regarding the Class A members/owners showing a loss could just be a means of fancy accounting. You'd have to see their actual broker statements to prove the claim that T3 "loses money year after year."
Whether they show a loss or gain is immaterial until the firm has fully exhausted their Class A equity and cannot maintain operations through its cash and financing activities, and thus begins to pull equity from Class B and C traders. However, this is NOT the case with T3's filings. In fact, for the most recent year, 2013, T3 showed net capital as defined by SEC Rule 15c3-1 of just over $7 million dollars!
