Burford Capital's operating profits tumbled by 21% in the year ending in December 2019, the litigation funder's latest financial report shows.

The report reveals that the litigation funding giant's operating profits fell by 21% to $279.3 million from $354.8 million over the 12 months of 2019. Its total income also decreased by 15% year-on-year to $356.7 million. The firm said in a statement that both decreases were due to a "lumpy" legal finance market.

At the end of 2019, the firm retained $206 million of cash on hand, compared with $277 million in January 2019, according to the full financial report.

Nevertheless, the firm claims it has seen a 30% year-on-year increase in demand for litigation finance capital and has built a portfolio worth $4.2 billion.

Anticipating a profit dip in realised and unrealised gains, the firm had a tumultuous 2019 after its value plunged by roughly half following the much-publicised short-selling attack by Muddy Waters in August. The attack also prompted a securities class action lawsuit against Burford in New York, which was dismissed in December.

The litigation funder is currently investigating claims of market manipulation and suspicious trading against Muddy Waters.
