Aon's Delaware Lawsuit Over Alleged Fraudulent LOCs Drags Shares to 215th in Trading Volume

On August 14, 2025, Aon (AON) shares fell 1.23% with a trading volume of $0.47 billion, ranking 215th in market activity. A Delaware lawsuit has intensified scrutiny over Aon’s collateral protection insurance (CPI) program linked to intellectual property lending. The Vesttoo Creditors Liquidating Trust alleges Aon’s CPI structure, marketed as a non-dilutive financing tool for IP-rich firms, relied on flawed valuations and forged letters of credit (LOCs) arranged with a China Construction Bank employee. The Trust claims $2.8 billion in fraudulent LOCs precipitated Vesttoo’s 2023 bankruptcy and left insurers with unsecured claims.

Aon denies the allegations, calling the case a “perverse attempt” to shift blame for Vesttoo’s fraud onto the broker. Internal communications reportedly highlighted risks of lending to pre-revenue companies and IP valuation challenges. The lawsuit could reshape industry practices, with insurers likely to tighten collateral verification, enhance valuation governance, and re-evaluate capital flows into similar structures. Legal outcomes may also influence broader litigation risks for insurers and brokers involved in CPI deals.

The case underscores operational risks in innovative insurance products. Insurers and reinsurers are already recalibrating underwriting standards, demanding bank confirmations for LOCs, and narrowing coverage terms. For Aon, the reputational and legal fallout could pressure its risk advisory business, while the sector grapples with balancing innovation and prudence. Key Delaware court proceedings will determine recovery prospects for creditors and the future viability of CPI models.

The backtest results indicate that a strategy of buying the top 500 stocks by daily volume and holding for one day from 2022 to 2025 yielded a 31.52% total return over 365 days, with an average 1-day return of 0.98%. This suggests the approach captured short-term momentum but remained exposed to market volatility and timing risks.
