The Libyan Investment Authority v Goldman Sachs International [2016] EWHC 2530 (Ch)
Expert evidence
Our expert provided two expert reports and oral evidence on the valuation and reserving of derivatives within a modern investment bank.
Our expert’s view on the true profit of the trades was accepted by the court, despite it contradicting the audited reports of a top tier investment bank.
Quant work
The solution we provided meant specialist consultants were engaged to build complex reserving tools against a challengingly short deadline. The compressed timetable for quant work allowed the expert to deliver detailed analysis of the figures provided by the bank, dissecting the bank’s profits calculations on a point by point basis.
Disclosure support
Our disclosure specialists identified critical evidence from the disclosure. They then re-engineered the information, building our own reports from the evidence. The results further demonstrated that the bank’s position was certainly wrong, and that it was very likely that our expert’s opinion had been correct.
Trial support
Our wider team supported the expert and provided insight during many stages of the case’s progression, including on the technical approach to the disclosure. Our input highlighted elements of the case that were previously misunderstood, despite the involvement of two other advisory firms prior to our engagement.
Acumen’s scalable model
We provided a team of four consultants to meet a challenging four month deadline. In this time we were able to complete the essential disclosure analysis, produce the complex bank reserving models and write the first report.
Cost Transparency
In our most rigorous reporting schedule to date, we sent daily billing updates to the law firm along with weekly sub-invoices to allow for full costs transparency and management.
