The Relevance and Benefits of LDI Customization

July 11, 2023

When discussing our LDI-Long Duration strategy with prospective clients, they often have questions about our custom benchmarks. The use of completion managers, while proven, can be arduous considering the need to consistently rebalance. This paper outlines how custom benchmarks could act as a complement to a pension fund's LDI portfolio and why we believe fixed income assets need to be better calibrated to liability profiles due to higher funding ratios.

KEY TAKEAWAYS
  • Custom benchmarks could complement a pension fund’s liability-driven investment (LDI) portfolio, as many investors require unique risk parameters (e.g., duration targets, credit quality, ESG considerations)

  • Rising discount rates led to an increase in pension funding ratios and we believe fixed income assets need to be better calibrated to liability profiles, which is when customization can be useful

  • The vast majority of LDI-Long Duration assets PPM manages on behalf of clients use custom benchmarks
