Several major technology and communications companies find they are included on a list of U.S. companies with a high danger of defaulting on their debt.

Bottom Rung list rose to 283 companies in the fourth quarter
Moody’s Investor Service’s Bottom Rung ranking released Wednesday singles out companies with weak liquidity – suggesting they could struggle to repay notes, bonds, loans and other credit.
On the list compiled with data from the fourth quarter are Advanced Micro Devices, Blockbuster, Clearwire Communications, Conexant Systems, Eastman Kodak, Freescale Semiconductor, Level 3 Communications, Palm, Quantum and Unisys.
