The pending sale of part of Home Depot took an ugly turn last night as three banks and three private equity firms entered into a showdown over financing. Home Depot dropped its asking price by over $1 billion, but the banks involved—JPMorgan Chase, Lehman Brothers and Merrill Lynch—have threatened to withdraw from a deal that may become the  first casualty of the credit crunch.
                                    
                                    
                                
                                
                             
                            
                            
                            
                            
                            
                                
                                
                                    
                                        In years past banks have happily funded-private equity buyouts at handsome terms, but the current crisis has left them with a $300-billion backlog in deals to be funded. Even after Home Depot's price drop the banks remain reluctant, and Bain Capital, Carlyle Group and CD&R, the three private equity firms at the table, have threatened a lawsuit.
