The Group-wide portfolio grew by 8% during the three months ended March 31, 2023. On a Burford-only basis, the portfolio of capital provision assets increased by 10% to $4.3 billion at March 31, 2023 as compared to $3.9 billion at December 31, 2022. The growth in the period is driven largely by growth in fair value adjustments in capital provision-direct assets, coupled with growth in new deployments and commitments. In addition, the Advantage Fund has contributed to an increase in capital provision-indirect assets.

Fair value of YPF-related assets
The determination of the fair value of the YPF-related assets—our financing of the Petersen and Eton Park claims—is based on the same methodology which we use to value all of our other capital provision assets. In June 2019, we sold a portion of the Petersen claim, constituting $100.0 million of a $148.0 million placement, to a number of institutional investors. Other third-party holders sold the remaining portion. Given the size of this sale and the participation of a meaningful number of third-party institutional investors, we concluded that this market evidence should be factored into our valuation process of the YPF-related assets. As a result, we have utilized the implicit valuation of the Petersen claim to calibrate our model to determine the fair value of the YPF-related assets in subsequent periods through March 31, 2023. Episodic subsequent trading of portions of the Petersen claim have not been factored into our valuation process of the YPF-related assets.
On March 31, 2023, the United States District Court for the Southern District of New York (the “Court”) issued its opinion and order in connection with the summary judgment motions filed by the parties (the “Ruling”) in the Petersen and Eton Park cases against the Republic of Argentina and YPF.
In summary, the Court decided that (i) Argentina was liable to Petersen and Eton Park for failing to make a tender offer for their YPF shares in 2012; (ii) YPF was not liable for failing to enforce its bylaws against Argentina; (iii) the
