Klein was hit with his first crisis in managing the Beatles when Clive Epstein, brother of Brian Epstein and chief heir to NEMS, the management company his brother had founded, sold NEMS to Triumph, a British investment group managed by Leonard Richenberg. NEMS held a 25% stake in the Beatles' earnings, which Klein as well as the Beatles themselves desperately wanted to buy out. This led to tough negotiations with Triumph. Klein ultimately secured the Beatles' rights in their previous work for just four annual payments amounting to 5% of their earnings. However, in the lead-up to those negotiations Richenberg commissioned a hostile investigative report on Klein, which "The Sunday Times" ran under the headline "The Toughest Wheeler-Dealer in the Pop Jungle".
