NationsBank Corp. has been trying to downplay the notion that the $3  billion of commercial paper it has filed to issue might be used for   acquisitions.   
The Charlotte, N.C., bank late last month filed a shelf registration  with the Securities & Exchange Commission that would enable it to issue   various kinds of commercial paper.   
  
NationsBank spokeswoman Martha Larsh insisted that the capital will be  used for "general corporate purposes," particularly the payment of maturing   debt. She declined to discuss the possibility of acquisitions, saying it   was the bank's policy not to comment on "speculation."     
However, analysts said NationsBank has been such an active acquirer in  the past that a $3 billion shelf registration tends to create such   anxieties. Indeed, analyst Allerton G. Smith, of Donaldson Lufkin &   Jenrette, said he was nervous about the bank's intentions when he first   heard of the registration.       
  
But he said the company's management reassured him that it "would not  use its debt financing in an acquisition to the extent that it would   threaten (the bank's) ratings by the creation of goodwill or double   leverage."     
Bank bond analyst Ann Robinson of Bear Stearns & Co. said there is  nothing unusual about in a big registration statement by the nearly $200   billion-asset bank. NationsBank is a "huge company and it is always in the   market," she said.     
"If investors want to be worried, they should be worried about First  Union," said Ms. Robinson, referring to recent acquisitions by   NationsBank's cross-town rival.   
  
Ms. Robinson said NationsBank's paper has gotten cheaper to investors in  the last month due to recent concerns over credit, consumer bankruptcy ,and   the increase in issuance by U.S. banks overseas, where NationsBank is an   active issuer.     
But she said the drop in price represents a buying opportunity, rather  than a cause for concern. 
"The spreads in all corporate paper has widened," she said, referring to  the yield on debt, which moves in the opposite direction from the price. 
She said the $3 billion registration statement caused "no reaction in  the spreads" on bank debt. 
  
NationsBank has several current shelf registrations with the SEC,  including one that allows issuance of senior and subordinated notes, a   commercial paper program and a program that allows issuance of Euro medium-   term notes.
