If any exposure which is to be risk-weighted under this sub-section becomes past due, it will be risk-weighted at the higher of risk-weight applicable under CA-4.2.21 or the risk-weight applicable under this sub-section e.g. if an exposure getting 90% risk-weight under CA-4.3.2 above becomes past due, it will be risk-weighted under CA-4.2.21 (at 100% or 150% whichever is applicable). However if an exposure getting 250% risk-weight under CA-4.3.2 above becomes past due, it will continue to be risk-weighted at 250%.
