Ambac Financial Group (ABK) took the earnings stage Monday night -- and the stock took a quick dive right out of the gate Tuesday morning, if that gives you any indication about the quarterly results. The bond insurer swung to a loss of $57.6 million in the second quarter, and warned that a bankruptcy filing is likely if it can't come up with a plan to restructure its liabilities within the next year.

The company's official release stated the matter quite plainly: "Ambac has insufficient capital to finance its debt service and operating expense requirements beyond the second quarter of 2011 and may need to seek bankruptcy protection."

In the buyout corner of the private equity business, "dry powder" continued to grow in 2009. Industry slang for capital available for investment, this measure points to how much activity private equity funds are capable of completing.

From December 2004 through December 2008, according to data from alternative investment research firm Preqin, the amount of funds on the sidelines surged from $178 billion to $501 billion for the buyout sector, nearly tripling. This year, buyout dry powder only increased by $3 billion, to $504.28 billion. While this may feel like little more than a rounding error, it suggests stability in the sector after what has been a trying climate for financial services business of all types.

Repros Therapeutics (NASDAQ: RPRX) easily takes the prize for most dismal earnings report of the day. Not only did the drug firm report a wider-than-forecast second-quarter loss, it also warned that bankruptcy is a real possibility unless the company can secure significant additional capital.

Specifically, Repros confessed to a second-quarter net loss of $8.9 million, or 59 cents per share, compared to Wall Street's consensus estimate for a loss of 46 cents per share. The company chalked up its poor results to a 16% annualized increase in clinical development activities for Proellex -- which has been placed on clinical hold by the FDA -- as well as a 60% year-over-year jump in general and administration expenses.

PNC Financial Services (NYSE: PNC) reported this morning it raised more than $600 million through an at-the-market offering of 15 million shares launched May 14.

Additionally, PNC said it has no plans to convert its preferred shares, and it expects to redeem the U.S. Treasury's $7.6-billion investment in its preferred shares "as soon as appropriate."

Banks need it. Home builders need it. Car companies need it. More banks need it. "It" is capital. Also known as equity. In reality, it's money. Banks need lots of it.

As we all know, there is a finite amount of everything. There is only so much money available for investing. The large banks have been at the trough and dipped, pulled out billions (names like Goldman Sachs (NYSE: GS), Bank of America (NYSE: BAC), Wells Fargo & Co. (NYSE: WFC). That was over the last few weeks. Stock was issued. Money flowed in. Things looked pretty good.

Regions Financial Corporation (NYSE: RF) started today's trading with a resounding thud after announcing a $1.25 billion stock offering. The regional banking issue said it will offer $1 billion in common shares and $250 million in new convertible preferred shares. The proceeds will address roughly half of the $2.5 billion in capital Regions was instructed to raise by the U.S. Treasury Department following its stress test results.

Despite a negative start to the session, RF has since ticked fractionally higher. The security has shed more than 34% of its value in 2009, and it's currently struggling under the weight of resistance from its 32-week moving average. Since 2007, RF has managed to notch just one weekly close above this steadily descending trendline.

The shares of PrivateBancorp (NASDAQ: PVTB) wasted no time in finding a fresh annual low this morning after the Chicago-based bank announced plans to slash its dividend by 87%. The quarterly payout will now be one penny per share, down from 7.5 cents per share. On the heels of this report, the stock quickly slipped to $9.65, marking its lowest price since September 2002.

"Given the current economic and regulatory environment, we felt this was a prudent step to take to further enhance our capital position and our liquidity," said President and CEO Larry D. Richman in a statement.

I have been asked whether there was anything in Chairman Bernanke's speech yesterday that changed my outlook on the prospects of nationalization for some of our largest financial institutions. In a word "no".

From my perspective, all Chairman Bernanke did was to confirm Monday's Joint Statement from the bank which offered that what the Government was hoping to implement were "temporary capital buffers" "to provide a cushion against larger than expected future losses, should they occur due to a more severe economic environment, and to support lending to creditworthy borrowers." And that the Government's security of choice would be "mandatory convertible preferred shares."

If the flow of political fund raising capital can be used as a gauge, then there's a strong message coming from the flow of campaign contributions from venture capitalists. Contributions by venture capitalists to Democratic candidates exceed contributions to Republicans by a nearly two to one margin. Red Herring reports, of the contributions from individuals and political action committees connected to the venture capital industry, Democrats have gathered $2.4 million compared with $1.4 million given to Republicans. That's quite a difference and it reveals a little about the current mindset of the finance industry in light of the coming elections.

National Venture Capital Association, is top contributor with $365,500 split 54% Democrat to 46% Republican. This seems to be a reasonable split. The giving picture from the number two and three contributors is much different however. The second largest VC contributor is Kleiner Perkins who piled 94% of $147,400 onto Democratic candidates. Third on the big donor list is Hummer Winblad which gave 100% of it's political contributions to the Democrats. The article from Red Herring expands on the list.

Most interesting to me is the fact that presidential candidate Barack Obama has handily out paced Hillary Clinton in total contributions from the VC camp. Top recipient, Obama has had $349,074 donated to his name while Clinton has only received $235,000 from similar sources. It's also important to note that Obama's total topped the VC's donations of $289,350 to Republican candidate Mitt Romney. Rudi Giuliani wraps up the top four with total contributions received of $178,400.

What do these funding dynamics indicate to you? Is there a fundamental shift taking place or are venture capitalists just hedging their bets? Do these patterns of political contribution reflect intent or are they simply a reaction to an overwhelming sense that something big must change? If political donations by venture capital organizations are an electoral thermometer, I must say it's getting mighty warm in here.
