The Board of IDFC Ltd has accepted the resignation of Lall as Executive Chairman of the company with effect from September 30, 2015, IDFC said in a filing to the BSE.
IDFC Bank will start functioning as a full fledged bank from tomorrow with over 20 branches.
"Lall will be taking over the position of MD & CEO of IDFC Bank Ltd with effect from October 1, 2015," IDFC added.
Meanwhile, Standard & Poor's Ratings Services today said it has affirmed its 'BBB-' long-term and 'A-3' short-term credit ratings on IDFC Ltd and then withdrew the ratings at the company's request.
"IDFC Ltd 'BBB-' rating affirmed with stable outlook; rating then withdrawn at the company's request," S&P said in a statement.
The bank license that IDFC received recently will help the group to access stable retail deposits and low-cost current and savings accounts and reduce reliance on wholesale funding, S&P said, adding the rating also reflected the fact that IDFC is transitioning into a bank.
