HTC has lost a number of senior figures over the past year, and if a report from Bloomberg is accurate we can add two more to the list of departing executives: Chief Marketing Officer Benjamin Ho and Engineering and Operations President Fred Liu. Ho, who took over as marketing head in early 2013, is said to have tendered his resignation and will reportedly depart by the end of the year. Sources for Engadget suggest that a lukewarm response to HTC's expensive Robert Downey Jr.-endorsed marketing campaign may have contributed to the CMO's exit. Meanwhile Bloomberg reports that Liu, a 16-year HTC veteran, will be retiring.

HTC's CMO and operations chief are out.

The report also states that former Samsung marketing exec Paul Golden, who was hired on a three-month contract earlier this year, has declined to stay on at HTC on a more permanent basis.

Today's news follows the departure of design lead Scott Croyle in April. And in 2013 HTC suffered several high-profile resignations including the VP of Global Communications, Chief Product Officer and the CEO of HTC Asia, among others.

A recent company reshuffle brought about a new "emerging devices" unit, with a "disruptive" tablet and wearable gadgets promised as HTC seeks to diversify its business. Various reports — and our own sources — indicate that the Taiwanese manufacturer will also produce a next-gen Nexus tablet for Google in the months ahead.

Amid falling revenues and ever-increasing competition in the smartphone space over the past year, HTC has found itself in a precarious financial position. However the company's recent Q2 2014 figures showed a return to profitability in the wake of its well-received flagship, the HTC One M8.

An HTC statement given to Android Central refers to "making hard decisions needed to continue growing as a global presence," but stops short of confirming any specific executive departures.

"HTC's dedication to innovation drives us to pursue our goals. We are taking the necessary steps to create a resurgence of the HTC brand. As a company, we will continue to push forward, making the hard decisions needed to continue growing as a global presence. We are confident that the business steps we have taken, and continue to take, are the right ones to lead to a strong resurgence of the HTC brand. HTC continues to invest in talent and recruitment as part of our broader human resources strategy to ensure the continued strength of our company's organizational structure."
