MOST NOTEWORTHY: UBS AG, KLA-Tencor and Level 3 Comm were today's noteworthy downgrades:

• Keefe Bruyette downgraded shares of UBS (NYSE: UBS) to Underperform from Market Perform as they expect as they expect further write-downs to erase profits in 2008.
• Oppenheimer downgraded shares of KLA-Tencor (NASDAQ: KLAC) to Underperform from Perform after checks indicated Intel (NASDAQ: INTC) has chosen Applied Materials' (NASDAQ: AMAT) reticle inspection tool for its entire 32nm node after a long period of evaluation against KLA-Tencor. Oppenheimer believes this represents a $300M shift from KLA-Tencor's dominant market share in reticle inspection.
  
• Jefferies cut Level 3 Communications (NASDAQ: LVLT) to Hold from Buy as they see limited opportunity for near-term share appreciation given the company's integration challenges and the added uncertainty from recent management changes.

• Keefe Bruyette downgraded Credit Suisse (NYSE: CS) to Market Perform from Outperform.
  
• Kroger (NYSE: KR) was downgraded to Underweight from Neutral at JP Morgan.
