- Adjusted pre-tax profits fall- Costs higher due to Transform - CEO says he is "not complacent"Barclays reported a 20 per cent drop in adjusted pre-tax profit to 4.97bn pounds in the third quarter, reflecting a decline in income and costs of a restructuring. Adjusted income for the nine months to September 30th fell 4% to £21.51bn, driven by a slump in the head office and in the investment bank.The bank has been working to streamline its business through its Transform strategy which incurred costs of £741m during the period.Adjusted operating expenses rose by £271m to £14,144m as a result.Nevertheless, statutory profit before tax improved to £2.85bn from £962m last year, reflecting a reduced own credit charge of £125m from £4bn. Credit impairment charges were down 6% to £2.3bn, principally reflecting improvements in corporate banking, mainly due to lower charges in Europe, and Africa RBB, in part due to foreign currency movements."I am particularly pleased with the performance of UK Retail and Business Banking, Barclaycard, Corporate Banking, and the Equities and Investment Banking units in the period," said Chief Executive Officer, Antony Jenkins."While the resilience of our performance is welcome, I am not complacent, and my Executive team know we must push harder in the final quarter and into 2014."Barclays has been embroiled in a series of scandals including its dealings with Qatar investors in 2008 and a fine for LIBOR rigging.The bank has already paid out £290m over rigging of the inter-bank lending rate.The company will pay a third interim dividend for 2013 of 1p per share on December 13th, resulting in a 3p dividend year to date.Looking ahead the lender said it will "continue to remain cautious about the environment in which we operate and our focus remains on costs, capital, leverage and returns to drive sustainable performance improvements".The share price rose 2.64% in opening trade.
