While we maintain a very healthy capital adequacy ratio, we have been judiciously churning tier-2 capital that was quite expensive. We have a follow-up round of tier-1 capital planned which will facilitate book-growth. Our NPA is largely from the historic book that has been adequately provided for, and our coverage ratio is high. We will, however, monitor and control any further slippages, says Srikrishnan H, MD & CEO, Karnataka Bank.
