While the company did not provide further details, it is speculated that Rekhi, who has been associated with the firm for over thirty years, may be elevated to the position of vice-chairman of USL.
"VK Rekhi has ceased to be the Managing Director of the company with effect from April 19, 2011, consequent upon the expiry of the period of his office as the managing director of the company," the filing said.
Rekhi will continue to be a director in USL and his replacement is likely to be named after a board meeting of the company later this month, a source said.
When contacted, a UB Group spokesperson declined to comment on the issue.
