RadioShack Corp. has secured a financial boost from GE Capital on the cusp of the crucial holiday selling season, Dow Jones Daily Bankruptcy Review reported today. The General Electric Co. unit will extend a loan of around $835 million secured by existing assets, including inventory, to refinance outstanding bank debt. The funds will free up cash for the electronics chain's overhaul as its losses mount. RadioShack had about $500 million of long-term debt outstanding at the end of June.
