The other shoe just dropped. If this was what shareholders were expecting, Monday's market action on Advanced Micro Devices (NYSE: AMD) suddenly makes perfect sense.

Monday morning, the chip designer announced a $300 million debt offering -- in effect just a refinancing move on a loan that was due for repayment this month. That announcement didn't mention interest rates or loan terms, but given the cushiness of today's interest rate environment, let's assume that the terms were at least relatively favorable. After all, AMD's financial house is in way better order than it used to be. Selling off the expensive manufacturing arm worked wonders for AMD's balance sheet.

But as it turns out, that was just the first jab in a one-two punch combo. After Monday's closing bell, AMD priced the debt deal. The gross opening balance grew to $500 million, giving the company plenty of coverage for its expiring debt notes. That's good, smart money management, as AMD needs to worry about liquidity. A quick call to AMD confirmed that the company increased the debt offering to $500 million as a result of "good response."

On the other hand, these 10-year bonds carry a 7% interest rate. That's far more expensive than the 5.75% and 6% bonds they replace. Shock, horror, panic. Right?

Well, not so fast. The old bonds are of the convertible ilk while the new ones don't seem to be, so this refinancing should remove the potential for some dilution. AMD classified the expiring bond batch as short-term debt.

All things considered, this looks like a good move. Longbow Research, which tags AMD with a buy rating and an $8 target price, notes that "cash preservation is a prudent move" in these uncertain economic times. Fitch reiterated its B+ credit rating on AMD as a whole and gave a B+/RR3 grade to the new debt -- junk bonds, but in the upper echelons of that murky classification. And in a bullish move, Fitch upgraded AMD's rating outlook from "stable" to "positive." That's a stark contrast to the negative ratings outlook the company gets from both Moody's and S&P.

AMD needs a fat wallet in its back pocket to battle Intel (Nasdaq: INTC) on the processor front and NVIDIA (Nasdaq: NVDA) in the graphics market. Free cash flows have been mildly positive for the last five quarters, but everybody knows that PC sales are struggling under the combination of macroeconomic pressure and invading tablets. It's just a good idea to save some cash for a rainy day, even if it's borrowed money.

Intel's dominant stature in the chip market only magnifies AMD's cash needs. The plucky underdog's only chance to stay relevant is to invest big in research and development -- and marketing isn't cheap when you don't own the leading brand in your core market.
