(Adds comments from treasurer, updates stock price.) 

Pitney Bowes Inc. (PBI) announced an exchange offer for the $375 million of its voting preferred shares outstanding.

Holders are being offered face value, including a $3,000 early premium per $100,000 of securities if tendered by 5 p.m. EDT Oct. 14, though that deadline is subject to change.

Treasurer Helen Shen said in an interview with Dow Jones Newswires that the auction-rate preferred shares were sold three years ago when that market was fully functioning. Auction-rate securities are debt instruments whose interest rates are meant to be reset periodically at daily, weekly or monthly auctions. But as the auctions began failing in February 2008, interest rates rose while investors were locked into long-term investments that had been promoted as safe and liquid.

To boost liquidity to holders of its voting preferred shares, Pitney Bowes is offering "a new security that has same terms and conditions but something more standard and liquid" with the present market, said Shen. "We view this as investor-friendly."

In July, Pitney Bowes posted an worse-than-expected 8.8% drop in profit as revenue declined on the weak economic climate and the stronger dollar. It also lowered it full-year outlook because it didn't see any signs mail-intensive industries were turning around. The company provides mail products and services.

Pitney Bowes shares were recently down 0.8% at $24.91 The stock is down 2.2% this year.
