CBB Bancorp Inc., parent of Commonwealth Business Bank, announced Tuesday that J. Duncan Smith has resigned from his position as chief financial officer, effective Feb. 8, to pursue other interests.

“We appreciate Duncan’s contributions during his time with us and wish him well in his future endeavors,” said CBB’s Joanne Kim, chief executive officer of the Koreatown-based banking company, in a statement.

Kim was not immediately available to comment further on Smith’s sudden departure.

Smith, who joined CBB just over four months ago on Oct. 2, previously was the executive vice president and chief financial officer of Community Bank in Pasadena, which was purchased in August by Ontario-based CVB Financial Corp., parent of Citizens Business Bank.

The $1.16 billion-in-asset CBB has eight branches in Los Angeles and Orange counties, one in Texas and two regional offices that specialize in Small Business Administration loans in Los Angeles and Dallas. It also has six loan production offices in Texas, Georgia, Colorado, Utah and Washington.
