(Bloomberg)--Pacific Investment Management Co., the world’s biggest bond manager, plans to start 19 actively managed exchange-traded funds as co-founder Bill Gross further diversifies the firm following Chief Executive Officer Mohamed El-Erian’s resignation last week.

Pimco will more than triple its active ETF lineup by offering variations of mutual funds such as Pimco Income, Pimco Unconstrained Bond, Pimco Municipal Bond and several StocksPlus and IndexPlus products, according to regulatory filings with the Securities and Exchange Commission on Jan. 24.
