U.K. bank Barclays announced adjusted profit before tax for 2013 of £5.2 billion ($8.5 billion) on Monday, ahead of its full earnings release on Tuesday.
The lender also said that statutory profit before tax would come in at £2.9 billion.
Barclays pre-released the data due to the Financial Times revealing the data in the diary section of Monday's publication, according to a person with knowledge of the situation. The bank released a brief statement to the London Stock Exchange at approximately 10.00 a.m. London time.
Shares of Barclays traded higher by 0.9 percent after the news.
Its adjusted pre-tax profit of £5.2 billion is below the £5.4 billion expected by analysts, according to Reuters. Last year, the figure rose 26 percent to £7.05 billion for the 12 months ended 31 December 2012.
