Safeway's gross profit fell 14 basis points to 28.6 percent of sales in the fourth quarter. Excluding a two basis point impact from fuel sales, gross profit dropped 16 basis points.

U.S. consumers, bruised by the worst downturn since the Great Depression, remain cautious about spending as national unemployment hovers around 10 percent and the prospect of a brisk economic recovery dims.

That strategy backfired when the economy tanked, leaving the company at a disadvantage to its rivals when it came to store prices.
LOSS ON CHARGES
Net loss for the fourth-quarter was $1.61 billion, or $4.06 per share, after a noncash goodwill impairment charge of $1.97 billion related to reduced market capitalization and the weak economy. Safeway reported net income of $338 million, or 79 cents per share for the year-earlier quarter.
Excluding the charge, the company earned 53 cents per share, matching the average forecast complied by Thomson Reuters I/B/E/S.
Total sales fell to $12.7 billion, down 8.1 percent from a year earlier, when there was an extra week in the quarter. Identical-store fell 4.1 percent, excluding fuel. Safeway defines identical stores, a key gauge of supermarket performance, as those operating in the same period during the current and previous years. The figure does not include replacement stores.
Safeway bought back $443 million in shares during the fourth quarter.
Shares in Safeway fell 55 cents or 2.3 percent to $22.95 in morning trading.
