Over the past decade we seen at least $1 trillion dollars spent by private equity firms. These firms have taken over companies for a pittance and then pillaged them by slashing employees and cutting costs. They then used the money to pay down debt rather than rebuilding the company.

Now all of the debt thrown on the acquired companies is coming due and it could cause another economic disaster, even bring down the economy.

Up until the credit crisis, private equity firms had it made. They had plenty of leverage to play with and could load up their acquisition targets with it. So, they could realize a fantastic return on equity, mitigate their own risks, and show that they were the studs of the Street.

Then, all that went away. Credit markets dried up, and private equity companies lost their acquisition fuel. The numbers aren't as big as they used to be, but it looks like the private equity market is back in action.

The private equity industry has been through the worst, but now it seems the situation is taking a turn for the better. Stephen Schwarzman, CEO of Blackstone (NYSE: BX) expects deal flow and IPOs to bounce, saying the economy is showing "more than green shoots" of recovery.

Schwarzman, speaking at the Super Return Middle East conference in Dubai, doesn't expect another slip into recession, but the full recovery will take time, for all the same reasons you've been reading on BloggingStocks for a while: tighter lending standards; uncooperative consumers who won't spend beyond their means and so on.

In the U.S., the outsourced healthcare professional staffing market is about $50 billion. And, it is likely to grow because of the complexity of regulations and cost pressures.

One of the largest outsources in the market is Team Health Holdings, which generated $1.33 billion in revenues last year. In fact, this week the company filed to go public.

The past two years have been terrible for private equity firms. But, now we're seeing signs of life.

If fact, this week there was a liquidity event. That is, the Blackstone Group (NYSE: BX) and Lion Capital have received a binding offer to sell Orangina Schweppes to Suntory (a major Japanese drinks company). It appears that the price tag comes to $3.82 billion.

Here are some highlights from last week's earnings coverage from BloggingStocks:

• Activision Blizzard Inc. (NASDAQ: ATVI) reported better-than-expected Q2 results, sending shares higher.
• Blackstone Group (NYSE: BX) said it swung to a Q2 profit despite a dearth of leveraged buyouts.
• CBS Corp. (NYSE: CBS) Q2 earnings declined but still topped estimates, sending shares higher.
• Coinstar Inc. (NASDAQ: CSTR) reported stellar Q2 results driven by its the popularity of RedBox.
• Clorox Co. (NYSE: CLX) posted solid Q4 earnings but said revenues were flat due to currency effects.
• Duke Energy Corp. (NYSE: DUK) lower Q2 earnings beat expectations by a penny but revenue fell short.

Despite the credit crunch and recession, private equity powerhouse, the Blackstone Group (NYSE: BX), was still able to post a profit of $180.8 million in Q2. How was this possible? It certainly helped that the equities markets surged. The upshot was that the Blackstone company portfolio had an average mark-up of 3%.

Yet, the fact remains that the buyout business continues to lag. While valuations are attractive, the problem is that banks continue to be stringy with funding. Unfortunately, without leverage, it's pretty tough to generate strong returns.

Shares of private equity firm Blackstone Group (NYSE: BX) surged 21% on Monday. The question is why?

Some have attributed the surge to investors buying on speculation of an upside surprise from Thursday's earnings report. Analysts surveyed by Thomson Reuters expect the New York-based company to report fiscal third quarter earnings of $0.09 per share, compared to a loss of $0.07 per share in the second quarter, but also a profit of $0.15 per share in the year-ago quarter. Revenue for the third quarter is expected to be 9.1% lower than a year ago to $341.9 million.

KKR & Co. is a step closer to being publicly traded, now that the board of its Amsterdam-traded buyout fun has given the green light. If a majority of the unitholders in KKR Private Equity Investors LP (OTC: KPE), the listed fund, consent, the transaction could be finished by October 1, 2009.

This would result in KKR's finally reaching an exchange. The private equity fund tried to go public via initial public offering (IPO) in 2007, after the Blackstone Group (NYSE: BX) raised $4.75 billion that way, but market conditions scuttled the attempt.

When The Blackstone Group (NYSE: BX) went public, many observers -- myself included -- were concerned by the total lack of corporate governance checks and balances.

But at the time, the private equity industry was so hot that Blackstone could do no wrong, and no one cared enough to complain. But now that KKR is mulling a plan to list on the New York Stock Exchange, things could be different. The wheels have come off the industry, at least for now, and the arrogant attitude of "We'll tell you what we feel like telling you and you'll like it" may not play so well.

While the Blackstone Group (NYSE: BX) is primarily known as a private equity firm, this actually understates things. In fact, it is a diverse global platform that spans hedge funds, corporate advisory and real estate investments.

Actually, the real estate segment is getting bigger. This week Blackstone announced that it raised a $4.3 billion real estate fund with the main focus on opportunities in Europe. It's called the Blackstone Real Estate Partners Europe III fund (for whatever reason, these funds can be a mouthful).

Back in 2007 -- at the height of the private equity bubble -- the Chinese sovereign wealth fund, China Investment Corp. (CIC), agreed to invest $3 billion in Blackstone (NYSE: BX). Of course, it was a disaster. In all, the investment lost roughly two-thirds of its value.

Despite all this, it looks like CIC hasn't given up on Blackstone. In fact, according to a piece in the Wall Street Journal, CIC is prepared to invest $500 million into a Blackstone hedge fund vehicle.

• Deutsche Bank upgraded Lloyds Banking (NYSE: LYG) to Buy from Sell as it believes shares are attractively valued based on the company's earnings potential post recession.
• Susquehanna upgraded MercadoLibre (NASDAQ: MELI) to Positive from Neutral based on valuation and improving macro trends. The firm has a $29 target on the stock.
• Piper Jaffray upgraded Williams-Sonoma (NYSE: WSM) to Buy from Neutral on valuation following the recent pullback.
• MetLife (NYSE: MET) and Torchmark (NYSE: TMK) were upgraded to Strong Buy from Outperform at Raymond James.
• Blackstone Group (NYSE: BX) was upgraded to Buy from Neutral at Goldman.

Private equity giant KKR & Co. (NYSE: KFN) posted a $1.2 billion loss last year -- compared to pretax net income of $815 million the year before. This is KKR's first loss in at least five years.

Bloomberg pins the blame on a drop-off in leveraged buyout transactions. A $1.4 trillion market in 2006 and 2007, only $212 billion was spent on takeovers last year, which was bound to put a dent in KKR's top and bottom lines.
