Could the 'bad' customer be KQ?
Many large contractors have not been paid by GoK. Other banks affected include BoA, I&M and KCB.
After 6 months the banks have to provision 100% but banks are allowed by CBK to provision early if they think the loan has gone 'bad' before the 6 months are up. Prudence requires earlier provisions in such cases.
Greedy when others are fearful. Very fearful when others are greedy - to paraphrase Warren Buffett
