NAIROBI (Reuters) - Standard Chartered Bank of Kenya posted a pre-tax profit increase of 3% in 2019 to 12.2 billion shillings (101.76 million pounds), it said on Thursday, as a focus on keeping a lid on bad loans restrained revenue growth. The lender, which is the fourth largest by assets in the East African nation, said its earnings per share edged up 2% to 23.49 shillings.
