The Boston Globe reports that credit card companies have been targeting subprime mortgage holders.

The evidence is stunning. Direct mail credit card offers to subprime customers in the US jumped 41% during 2007's first half, compared with the first half in 2006. By contrast, direct mail offers targeted at customers with the best credit fell 13%. During this same period, defaults on subprime mortgages rose significantly -- in June, nearly 20% of subprime mortgages were at least 60 days past due, and more than 1 in 20 were in foreclosure.

The leaders in selling higher interest rate credit cards to the financially vulnerable includes some subprime mortgage leaders. Here's a partial list:

DOW JONES & COMPANY (NYSE: DJ)

Could it happen? Could News Corporation (NYSE: NWS) pull its offer? They could, and the fear is absolutely there. That's why the stock has fallen. For one, the Bancroft family, which controls the majority of Dow Jones' shares, hasn't formally accepted Rupert Murdoch's $5B, $60 a share offer. And no one else has come forward with a competing bid. But it does seem that both sides are moving together in the same direction. Okay, but somebody should make up their mind -- either way -- and stop fiddling around.

EXPEDIA INC (NASDAQ: EXPE), IAC/INTERACTIVECORP (NASDAQ: IACI)

Barry Diller is back at it. The chairman and CEO of IAC/InteractiveCorp, who is also chairman of the board and a senior advisor to Expedia, is working to take online travel firm Expedia private at $30 a share. Part of any deal will involve Expedia's TripAdvisor being spun off with about 400 jobs being lost in that shuffle.

PENN NATIONAL GAMING INC (NASDAQ: PENN)

After many, many laps around the track, this race is over, as race track and casino operator Penn agreed to be acquired today by Fortress Investment Group LLC (NYSE: FIG) and private equity firm Centerbridge Partners. All cash, baby, in a deal worth $8.9B that includes $2.8B of assumed debt. Everyone to the Winner's Circle.

Happiness increases with age, according to a study conducted for HSBC Holdings plc (NYSE: HBC) and reported by MarketWatch. What is happiness? Why does it increase with age?

This study implicitly defined happiness as a combination of health, freedom from financial worry, and control over one's life. According to the study, a majority of people in their 60s and 70s report being healthy and in control of their lives -- and as happy as many respondents in their 40s. This is the key finding of HSBC's survey of 21,000 people in 21 countries and spanning four age groups, each decade from age 40 to age 80.

Health is surprisingly good but varies by country. Overall, just 14% of those 60 to 79 in the U.S. said they're in poor or very poor health, while 86% say they're in fair, good or very good health. Poor health is lower in some countries -- Brazil (10%) and Mexico (10%) -- and higher in others -- Asia (18%), South Africa (32%), Russia (35%) and Turkey (35%).

Kohlberg Kravis Roberts & Co. (KKR) is one of the pioneers of leverage buyouts (LBOs), getting its start in the mid 1970s. During that time, LBOs were considered a niche, not a growth business.

Of course, things are a lot different today. Private equity firms are becoming a big power in finance. For the most part, however, the top firms have concentrated on U.S. targets.

That's changing. Today private equity firms are looking overseas for opportunities.

For example, today KKR announced that it has hired Sir John Bond, who recently retired as the group chairman of HSBC Holdings. He's hired on at KKR as a "senior adviser."

Translated, that means he will not get into the nitty-gritty of dealmaker; rather, his focus is likely to use his extensive network. His particular strength is in Asia, where buyout activity has been relatively light.

Seems like that is likely to change very soon.
