Definition:Look-through approach
🔍 Look-through approach is a valuation and risk-assessment methodology used in insurance regulation that requires an insurer to identify and evaluate the underlying exposures within collective investment vehicles, special purpose vehicles, and other pooled structures rather than treating the fund or vehicle as a single, opaque holding. The principle is straightforward: if an insurer owns shares in an equity fund, the capital charge should reflect the actual equities, bonds, or derivatives inside that fund, not simply the fund's wrapper. This approach is formally mandated under Solvency II and has parallels in other risk-based capital regimes, including Bermuda's BMA framework and elements of China's C-ROSS.
⚙️ Applying the look-through in practice means an insurer must decompose each indirect holding into its constituent asset classes and run the relevant stress scenarios — market risk, credit risk, concentration risk — at the granular level. Under Solvency II's Delegated Regulation, if the insurer cannot fully identify the underlying assets, it must treat the entire investment under the most punitive capital charge applicable to any asset the fund is permitted to hold according to its mandate. This creates a strong incentive for insurers to obtain transparent data from asset managers and fund administrators. The operational burden is significant: large insurers with diversified investment portfolios may hold hundreds of funds, each requiring periodic disaggregation and mapping to regulatory risk buckets. Insurtech and regtech vendors have built dedicated platforms to automate this data collection, cleansing, and mapping process.
💡 Without the look-through approach, insurers could inadvertently — or deliberately — obscure concentrated or high-risk positions inside opaque fund structures, understating the true risk on their balance sheet and the capital needed to support it. The approach therefore serves as a critical transparency mechanism, ensuring that own funds are genuinely sufficient relative to actual economic exposures. It also affects investment strategy: insurers increasingly favor separately managed accounts or funds that provide daily position-level transparency, partly because the data requirements of look-through compliance are easier to meet. For risk management teams, the discipline of look-through analysis often uncovers unintended concentrations — for instance, multiple funds holding the same sovereign or corporate issuer — that would otherwise go unnoticed at the aggregate portfolio level.
