For the six months ended June 30, 2024, net realized gains were $175.3 million, comprising $202.1 million of gross realized gains, offset by gross realized losses of $26.8 million. For the six months ended June 30, 2023, net realized gains were $133.8 million, comprising $161.3 million of gross realized gains, offset by gross realized losses of $27.5 million. The increase in net realized gains is primarily due to more case activity during the six months ended June 30, 2024 which led to favorable conclusions with no single asset significantly impacting the result. Overall, net realized gains resulted from $304.9 million in realizations for the six months ended June 30, 2024 as compared to $285.9 million in realizations for six months ended June 30, 2023.
Fair value adjustments, net of previously recognized unrealized gains/(losses) transferred to realized gains/(losses), are affected by a number of factors, including changes in discount rate, duration and litigation risk premium, the reversal of previously recognized unrealized gains and their associated transfer to realized gains upon conclusion of an asset and actual performance of assets as they pass through milestones. All of those factors contributed to the decrease in fair value adjustments to $25.4 million for the six months ended June 30, 2024 as compared to $374.0 million for the six months ended June 30, 2023, with no individual asset having a material impact other than the absence of the fair value adjustment for the YPF-related assets of $277.3 million arising primarily from the March 2023 Ruling (as defined below) versus the comparative period.
As part of our fair value methodology, we discount the expected future cash flows. The weighted average discount rate increased by 34 basis points to 7.3% at June 30, 2024 from 7.0% at December 31, 2023 and, in isolation, resulted in lower net present values. As an indication of the impact, the fair value of the capital provision assets had a sensitivity of a $78.9 million decrease in capital provision income for an assumed increase of 50 basis points in discount rates at June 30, 2024. The sensitivity figure is a point in time calculation at June 30, 2024 and therefore an approximation of the impact the change in discount rates would have had on capital provision income.
Fair value is also impacted by changes in the adjusted risk premium, which marginally increased to 30.7% at June 30, 2024 from 30.2% at December 31, 2023. This metric is a risk adjustment (haircut) applied to the potential proceeds due to us in the event of a successful litigation outcome and is intended to reflect the remaining litigation risk. The impact of the addition of newly acquired or originated capital provision assets during the period (which generally have higher risk premiums at the start of the capital provision asset’s life) was largely offset by net favorable developments across the rest of the portfolio.
Plus/(Less): Third-party interests in capital provision assets
Third-party interests in capital provision assets were a reduction in capital provision income of $6.3 million for the three months ended June 30, 2024, as compared to an increase in capital provision income of $4.8 million for the three months ended June 30, 2023. The change was primarily driven by the impact of passage of time resulting in an increase in the fair value of the financial liability owed to Colorado, which was reflected as a reduction of $7.4 million to us. In comparison, the financial liability owed to Colorado decreased for the three months ended June 30, 2023, which was reflected as a positive $4.8 million to us, due to the impact of the increased discount rates being greater than the impact of passage of time, which resulted in an unrealized loss on the underlying YPF-related assets.
Third-party interests in capital provision assets were a reduction in capital provision income of $11.5 million for the six months ended June 30, 2024 as compared to a reduction of $95.5 million for the six months ended June 30, 2023. The financial liability owed to Colorado increased during the six months ended June 30, 2024 driven by the impact of passage of time, which was reflected as a reduction of $12.8 million to us. The lower reduction period-over-period was due to the absence in the six months ended June 30, 2024 of a large write-up in the YPF-related assets which accounted for $95.0 million of the impact in the six months ended June 30, 2023.
Asset management income/(loss)
Asset management income remained consistent at $1.6 million and $3.5 million for the three and six months ended June 30, 2024, respectively, as compared to $1.9 million and $3.9 million for the three and six months ended June 30, 2023, respectively. As BOF-C is a consolidated entity, asset management income from this private fund is eliminated on a consolidated basis. See “—Asset management” for a discussion of our asset management income on a Burford-only basis.
Marketable securities income/(loss) and bank interest
Marketable securities income and bank interest increased 307% to $6.3 million for the three months ended June 30, 2024 as compared to $1.5 million for the three months ended June 30, 2023. Marketable securities income and bank interest increased 179% to $12.9 million for the six months ended June 30, 2024 as compared to $4.6 million for the six months ended June 30, 2023. The increase in both the three and six months ended June 30, 2024 is predominantly
