British banking giant Barclays has posted an adjusted attributable profit of £2.69bn for the full-year 2015, a decline of 3% compared to £2.78bn in the prior year.

The bank’s adjusted pre-tax profit for the year was £5.40bn, down 2% from £5.50bn a year ago.

Total operating expenses on an adjusted basis were £16.99bn, a 6% decline from £18.07bn a year earlier.

Adjusted total income net of insurance claims decreased 5% to £24.53bn from £25.73bn in 2014.

Barclays’ Personal and Corporate Banking arm, which also includes the wealth business, has registered an attributable profit of £2.18bn in 2015, up 6% compared to £2.06bn in 2014.

The unit’s pre-tax profit increased 5% to £3.04bn from £2.88bn in the prior year.

Total income decreased 1% to £8.72bn from £8.83bn a year ago, while total operating expenses dropped 4% to £5.27bn from £5.47bn a year ago.

Barclays group CEO Jes Staley said: "Our 2015 performance demonstrates the strength of Barclays’ core business, as well as the importance of continuing to make progress in running down non-core and controlling our costs to deliver the returns our shareholders deserve in a reasonable timeframe."

"Risk weighted assets in the non-core were down further to £47bn, having more than halved since the unit was created, and maintaining this very good momentum is critical to our future success. Group adjusted operating expenses were nearly £100m below guidance, and we have seen our capital position strengthen further with our CET1 ratio increasing to 11.4% and our leverage ratio improving to 4.5%," Staley added.
