(Bloomberg) -- Vanguard, the world's largest mutual fund manager, said it attracted a record $305 billion last year — an annual total that some firms need decades to reach. 

Vanguard's take, which tops the firm's previous record of $276.4 billion in 2015, includes $93 billion that went into ETFs, up from $76 billion the year before, spokesman John Woerth wrote in an e-mail. While the bulk of the money flowed into products that track indexes, more than $50 billion was absorbed by active funds that buy bonds or a mix of stocks and bonds, Woerth said.
