Barclays reported a full-year net profit of £1.4 billion ($1.82 billion) for 2018 Thursday, swinging back to the black after 2017 losses.

In 2017, the British bank posted a significant loss of £1.92 billion, after it was hit by a one-off £901 million charge on U.S. deferred tax assets.

Here are some other takeaways from Barclays' 2018 results:

The bank reported its 2018 core capital ratio at 13.2 percent, unchanged from the previous year.

Group profit before tax increased 20 percent to £5.7 billion

Earnings per share excluding litigation and conduct for the full year was 21.9 pence.

Barclays also set aside a Brexit provision of £150 million in its 2018 results. Shares of the bank jumped more than 4 percent in early deals on Thursday.

"In the fourth quarter, we took a special impairment charge of £150 million, given the uncertainty around Brexit. We think that was a prudent and proper thing to do," Jes Staley, chief executive officer of Barclays, told CNBC Thursday.

"There is a lot of uncertainty out there. What is important for Barclays is we are a British bank and we are staying committed to the U.K."
