 Barnes & Noble Warns on Nook Businessu
 
 By JEFFREY A. TRACHTENBERG
 
 Barnes & Noble Inc. said on Wednesday that its Nook business will perform worse for the fiscal year ended April 27 than forecast as recently as early January.
 
 The retailer said that the Nook business, which includes tablets, e-readers and e-books, would have losses before interest, taxes, depreciation and amortization greater than in fiscal 2012, when its Ebitda losses amounted to about $262 million.
 
 The statement contrasted with the retailer's early January statement the Nook losses would be about comparable to 2012.
 
 Barnes & Noble also said that its fiscal year 2013 Nook Media revenue, which includes the college bookstores as well as the Nook devices and e-books, will be less than $3 billion. In early January the bookseller said that it expected that revenue would be about $3 billion.
 
 In addition, Barnes & Noble delayed its earnings reporting date to Feb. 28, from its originally scheduled date of Feb. 19.
