May 15 - Upscale retailer Neiman Marcus [NMRCUS.UL] is trying to renegotiate a $600 million credit line due to mature next fall, the New York Post said, citing two sources.

The operator of both its namesake and Bergdorf Goodman stores is having trouble refinancing the asset-based revolving credit facility, which is to mature in October 2010, the paper said, citing a source.

The company is not on the verge of bankruptcy and talks with its banks are ongoing, sources told the paper.

Neiman, like other upscale retailers Saks' (SKS.N) and Nordstrom Inc (JWN.N), has not been been spared in the recession, as even wealthier clientele cut back on spending.

Reuters could not immediately reach Neiman Marcus for comment, outside regular business hours. (Reporting by Anurag Kotoky in Bangalore; Editing by Lisa Von Ahn)
