According to TMZ, the partnership between Jay-Z and the popular cognac brand D'Ussé is looking like it's coming to an end over Hov's dispute with D'Ussé's parent company, Bacardi. 

Jay is now selling his stake in the brand and demands Bacardi engage the buyout process "in good faith." As TMZ reports, "Jay's company, SC Liquor, exercised its right to a buyout about a year ago. Under their agreement, Bacardi now has to "negotiate in good faith" to come up with a fair price for Jay's stake in D'Ussé." 

Court documents suggest both sides aren't close in terms of valuation. Although the numbers have been redacted from the court docs, it is reported that the value Jay's side sees in this isn't being similarly reflected from his counterparts at Bacardi.
