  • Praise and thanks for Tachibana
  • Chris Coldren taking over in the interim
  • Search for a successor

(exechange) — Milpitas, California, June 7, 2018 — Aaron Tachibana, finance chief of Lumentum, leaves the position. It is an abrupt change. As announced by Lumentum Holdings Inc. in a news release on Thursday, June 7, 2018, Aaron L. Tachibana leaves his post as Chief Financial Officer at the telecommunications equipment company after less than three and a half years in the role, effective immediately.

Among the 3,000 largest publicly held companies incorporated in the U.S. based on market capitalization, the average tenure of the CFOs who departed over the past 12 months was 6.7 years, according to data compiled by exechange.

Tachibana leaves the company effective August 31, 2018.

Lumentum will undertake a search for a successor.

Tachibana’s duties will be taken over in the interim by Chris Coldren, most recently Senior Vice President Strategy and Corporate Development of Lumentum Holdings Inc.

“To pursue other interests”

Tachibana’s sudden departure from the CFO post is explained as follows. Lumentum said: “Aaron Tachibana, Executive Vice President and Chief Financial Officer, has resigned from the company to pursue other interests and will remain with the Company through a transition period which will end on August 31, 2018.”

The phrase “to pursue other interests” opens the door to speculation.

Precise information about Tachibana’s future plans was not immediately available.

“Not related to any issues”

“Mr. Tachibana’s departure is not related to any financial performance, policy, or control issues or any disagreements on accounting or financial reporting matters,” Lumentum said.

It is a phrase that may be intended to prevent false rumors. It may also fuel further speculation and raise more questions than it answers. Such a phrase should be read very carefully. The exact wording may be insightful.
