In earnings news, Apple continued the wave of good technology reports, with sales up 43 percent and profits up 36 percent on strong sales of its Mac computer line, though iPod sales were flat.

But Starbucks was “scalded,” as the Journal says on B3, by slower sales in the first quarter and says it expects to report lower profits. Same-store sales were down in the “mid-single digits,” it said, hurt by the housing busts in California and Florida, which combined account for nearly a third of its sales.

Skimping on sauce won’t pack ’em in

It’s a bad time for restaurants generally, which the WSJ on page one says is in its “worst slump in decades” with “almost all segments struggling.”

Many chains have scaled back expansion plans or cut costs by skimping on things like extra sauce and free sour cream. Some are shuttering sites and laying off workers. Private-equity firms, which plunged into the business earlier this decade using gobs of borrowed money, are now especially vulnerable as those debts come due.

We say good riddance to the sour cream, but extra sauce? Slow down!

The Journal says eating in has big repercussions for the economy since restaurants are the third biggest employer in the country and kindly notes that “Many of those jobs are held by the poor and immigrants who have few other options for work.”

Village Inn, a diner chain where we many nights of our youth were misspent, is shaving an ounce off its hash brown servings and studying the implications of reducing the number of sugar packets it puts out on the tables.

The WSJ says analysts don’t expect things to turn around soon: there’s a glut of restaurants, with 45 percent more open now than in 1990.

Bond insurers bomb

It’s been a while since we heard from the bond insurers, and true to form, they’re back in the papers with bad news. Ambac Financial lost $1.7 billion in the first quarter, about eight times the loss analysts had expected, the WSJ says on its Money & Investing front. Its shares plunged 43 percent to their lowest level yet, and rival MBIA’s were down a third.

That sparked our “Financial Recovery? Not Just Yet” Quote of the Day from Bloomberg:

“Just when you thought things are getting back to normal, there are these horrible numbers,” said Robert Haines, an analyst at CreditSights Inc., an independent bond research firm in New York. “If trends like this continue, they are going to have to go back to the markets very soon” (to raise capital).

But Bloomberg quotes an analyst saying the company may not be able to raise more capital, meaning a downgrade by the credit-rating firms will be “unavoidable.”

The papers say the losses raise concerns yet again about whether it will be able to keep its AAA credit rating, which is crucial to its business and to the prices of the $1 trillion in debt it has insured. If the firms are downgraded, it would spark a wave of forced selling that would hammer financial markets.
The FT says Ambac warned that its subprime losses may reach $3 billion, though it doesn’t say if that’s for future losses or includes past ones.

The Times slaps a Reuters story on C3 that reports Ambac saying it’s “writing very little new business” now.

Safety in numbers

The Journal says on C1 that Wall Street is trying to organize to self-regulate the exponentially growing market for credit-default swaps—contracts bought to insure bonds or other debt against the possibility that a company won’t be able to pay it off.

Any steps to shore up this $45 trillion market and to make it more transparent are, to say the least, welcome.

Best practices

The Times reports on C1 that a former Bristol-Meyers Squibb executive has been indicted on federal charges that he negotiated a secret deal to keep a competitor from producing a generic version of Bristol-Meyers’s best-selling drug Plavix—and then kept it from regulators.

The company pleaded guilty to related charges last year and paid a million-dollar fine.

Hey, I could buy a home now!
