The amount of investable assets available to venture capital funds has basically been a growth story since 2003. Dry powder slipped 7% in 2004 and 10% in 2008, but increased in every other year over this period.

Now, the dry powder number sits at $155 billion, according to alternative investment research firm Preqin, just off its December 2007 peak of $160 billion. The big number, however, masks a wide range of market situations for venture capital funds. Dry powder levels vary by strategy and region. To get a sense of what's going on behind the scenes, check out the five facts below about venture capital dry powder.

Private equity returns are down 27.6% year-over-year for the 12-month period ending July 30, 2009, according to a Preqin report received by BloggingStocks. The London-based research house notes, however, that the global private equity industry's dry powder (i.e., uncommitted assets) continues to exceed $1 trillion, suggesting that there is still plenty of capital waiting for a rainy day.

Returns for the past 12 months reflect all the nastiness we've seen and lived -- bailouts, company collapses, equity and credit market mayhem and unemployment rates dangerously close to double-digits. But, the money is still coming in. Preqin puts the rate by which contributions outpaced distributions at 235% for buyout funds in 2008. This category raised $148 billion while distributing only $63 billion, making last year the most imbalanced for these two measures in history.

Private equity investors are using current financial market constraints on liquidity to negotiate favorable deals, as private equity general partners have watched the values of their portfolios fall profoundly. Efforts to attract additional investment haven't been easy, as potential limited partners are reluctant to make long commitments in an uncertain marketplace. This has given limited partners a stronger position from which to negotiate both fees and terms and conditions.

Limited partners are getting a leg up on the private equity funds in which they invest, signaling a change from the historical trend in which funds could push for aggressive compensation based on the returns they provide. In a poll conducted by Preqin, 43% of investors noted a power shift from fund to limited partner, with only 2% seeing a shift toward the general partner.

The Blackstone Group LP's (NYSE: BX) $930 million purchase of GSO Capital Partners early this year didn't get much fanfare. But so far, it looks like a stellar deal.

Simply put, GSO is a hedge fund that's focused on distressed debt. Of course, with the slowing economy, GSO is in a prime spot to capitalize on some nice opportunities.

But there is more. Basically, GSO has become a key source of buyout financing (this is according to Bloomberg.com).

For example, when the Weather Channel was up for sale, it was tough to get financing for the deal. So why not GSO?

It worked. In the end, Blackstone and Bain Capital teamed up with General Electric (NYSE: GE) to pull off the acquisition. As for GSO, it provided higher-risk mezzanine debt financing.

Of course there are issues. After all, Blackstone has a conflict. But at the same time, the financial markets are mired in a credit crunch. So, if there are essentially no alternatives, GSO is probably going to provide the best offer.

More importantly, Blackstone realizes that there are some juicy opportunities right now. Thus, by having the GSO advantage, Blackstone certainly is positioned nicely.
