Pacific Investment Management Investment Co. announced a restructuring of its leadership on Wednesday that shifts the balance of power at the giant money manager away from founder Bill Gross.

The moves comes less than a week after Pimco said its chief executive officer, Mohamed El-Erian, would step down in mid-March and as the firm deals with large outflows from its signature bond fund and an equities business that has yet to gain traction.

Mr. Gross said in an interview with The Wall Street Journal on Wednesday morning that the appointments of four new deputy chief investment officers, in addition to two named last week, are designed to show investors that Pimco isn't just a bond shop.

Several of the new appointments have specialties outside of fixed-income, which has long been Pimco's primary business. Pimco manages about $2 trillion, including Mr. Gross's Total Return fund, which is the largest bond fund in the world.

"It's going to be a little different and more strategic, with more balance between them," Mr. Gross said. "They're going to be more empowered to operate more in their respective areas."

The moves effectively tilt the balance of power away from Mr. Gross, who previously split investment-decision duties with Mr. El-Erian. Mr. Gross, 69 years old, says he will run investment committee meetings one day a week now, and allow his six deputies to run them on the other days.

"Frankly, as I always told Mohamed, I always thought I did better when he was leading as opposed to when I was," Mr. Gross said. "When you lead you have to make sure everyone has a chance and there's lunch served and you have to be a host. I'm better from the side sometimes than the front."

Mr. Gross's Total Return Fund saw record outflows of $41.1 billion last year, and had $237 billion under management at the end of 2013. The fund posted a loss in 2013 of 1.92%.

"There will be those times when the bond market has a minus side in front of it and that was 2013," Mr. Gross said. "The Total Return Fund will stay, in my humble judgment, the largest bond fund in the world."

Douglas Hodge, Pimco's newly appointed chief executive, said in an interview Wednesday that he will focus on building out the giant money-manager's equity business, an area it has struggled to grow in the past.

Mr. Hodge, 56 years old, is replacing Mr. El-Erian, who spent seven years atop the Newport Beach, Calif. firm, a unit of German insurer Allianz SE.

Mr. Hodge said Pimco will build out its equity business internally and not through acquisition.

"We've been bond managers for forty years, but we all recognize that because we serve a broader clientele, we have to evolve as well," Mr. Hodge said.

Pimco's push into equities has been slow going. The firm's six stock funds had just $10 billion in assets under management last year after the firm's former head of global equities, Neel Kashkari, departed. The firm, known for its fixed-income prowess, has $2 trillion under management but also saw outflows in its bond funds last year amid a stock-market rally.

Unlike Mr. El-Erian, who also served as co-chief investment officer, Mr. Hodge said he would focus solely on the direction of the company, and won't manage any money. Mr. Hodge also said he won't be the public face of Pimco like Mr. El-Erian, in part because he won't be managing money and doesn't have the same international public-policy background.

"I'm not Mohamed," Mr. Hodge said. "To the extent that I have a public presence, my focus will be different."

Pimco previously named Andrew Balls and Daniel Ivascyn as deputy chief investment officers.

The firm on Wednesday announced the appointments of four new deputy chief investment officers. Mr. Hodge said the moves are an attempt to develop talent around Mr. Gross.

"We look at what we've done in terms of the deputy [chief investment officers] and firmly believe that it positions us well for the future," he said.

Pimco named the following as new deputy chief investment officers: Mark Kiesel, a managing director in the Newport Beach office and global head of the corporate bond portfolio management group; Virginie Maisonneuve, London's managing director and global head of equities; Scott Mather, a Newport Beach managing director and head of global portfolio management; and Mihir Worah, another Newport Beach managing director and head of the real return portfolio management team.

The company also appointed former employee Sudi Mariappa as managing director and generalist portfolio manager in Newport Beach.

The appointments are a way to show clients "not only that there is a very strong team ready to step up, but that it's a fairly large team and that they want these folks to have a higher profile outside the company, " said Eric Jacobson, senior fund analyst at research firm Morningstar Inc. The moves "reassure clients they're taking succession planning very seriously," he said.

In addition, the firm said on Wednesday that managing director and equities portfolio manager Charles Lahr will leave the firm to pursue other opportunities. Marc Seidner, managing director and portfolio manager, is also stepping down to take a job in Boston.
