Vol. 3 - Targeting Outperformance of ASC Liabilities

Justin Harvey, CFA, ASA, Solutions Strategist for Multi-Asset Solutions

Executive Summary

  • Recent improvements in the funded status of many corporate defined benefit plans have accelerated interest in liability-driven investing (LDI) and led many sponsors to more clearly articulate their LDI objectives. However, the fixed income benchmarks typically used to measure the performance of LDI strategies can be improved.
  • T. Rowe Price has developed a methodology for constructing custom LDI benchmarks at the most granular level—from the individual cash flows, both principal and coupon, derived from a given fixed income opportunity set.
  • We provide a hypothetical example of a sponsor seeking to outperform liabilities as valued using accounting standards codification discount rates. A custom benchmark enables sponsors, consultants, and managers to focus on performance relative to the plan liability, which in our view is ultimately how LDI mandates should be measured.

As corporate defined benefit plans increasingly have shifted their focus to portfolio de-risking, many have sought fixed income benchmarks that are better aligned with the specific objectives they hope to achieve through liability-driven investing (LDI). 

Some sponsors have shifted to longer-duration measures, such as the Barclays Long Credit Index or Barclays Long Government/Credit Index, while others have adopted compound benchmarks or duration-targeted indexes. 

T. Rowe Price believes an even higher level of customization is both necessary and feasible. Accordingly, we have developed a methodology for constructing custom fixed income benchmarks at the most granular level possible—the individual cash flows, both principal and coupon, derived from a given fixed income opportunity set. 

Based on the bonds in the relevant opportunity set, we create a benchmark that matches, as precisely as possible, a plan’s projected liability cash flows. To ensure continuous liability matching, this investible benchmark is then reset each year to reflect the plan’s actuarial experience, new pension cash flow accruals, and bond market developments.1


Many corporate defined benefit plan sponsors are focused on improving balance sheet funded status, as defined by accounting standards codification (ASC), via fixed income allocations that create greater exposure to credit risk than the bonds used for liability calculations. In such cases, we believe that linking the outperformance target to liability returns is essential to achieving the desired objective.

To highlight the potential benefits of T. Rowe Price’s LDI customization process for these sponsors, we have created a benchmark for the hypothetical plan liability structure shown in Figure 1 (below). We assume the sponsor’s LDI objective is to outperform pension liability returns—based on U.S. ASC discount rates—by 100 basis points (bps) per year. In our view, such a benchmark might be appropriate for sponsors seeking to:

  • outperform the liability in order to reduce funding deficits,
  • maintain an open and ongoing plan,
  • better align and attribute LDI investment manager performance,
  • incorporate an active credit strategy designed to achieve the outperformance target.

We believe the custom benchmark would provide a much more precise match of the liability structure than would be possible using a standard market-weighted index, such as the Barclays Long Credit Index (Figure 1A). However, given the sponsor’s objectives, the opportunity set for the custom benchmark (Figure 1B) can be broadened to include bonds of lower quality than would be used for liability calculations.


Custom LDI Benchmarks Can Provide More Precise Matching of Plan Liability Cash Flows Hypothetical Plan Cash Flows Valued Using ASC Discount Rates


Data as of 30 Sept 2015

In our example, the investment universe incorporates the entire investment grade (IG) spectrum (AAA to BBB-), essentially matching the quality constraints for the Barclays Long Credit Index. This opportunity set reflects the fact that many LDI mandates currently use the Barclays Long Credit Index as a benchmark, which implies that some sponsors are willing to accept at least an equivalent degree of credit risk in other LDI portfolios. The 10 largest issues in our hypothetical custom benchmark are shown in Figure 2 (below).

A benchmark constructed in this manner will have similar duration, convexity, and cash flow characteristics as the liability, which should facilitate the attribution of LDI portfolio performance. The portfolio manager’s objective, then, would be to construct a portfolio with similar characteristics as the custom benchmark, while employing his or her skills in security selection to seek to generate a 100 bps yield advantage over the liability discount rate.

Figure 3 (below) shows some of the key characteristics of a hypothetical portfolio constructed using this approach. Such an LDI mandate could be used to complement and diversify from other LDI managers that have similar outperformance targets, but relative to published market-weighted benchmarks rather than an investible representation of the plan’s liability.

T. Rowe Price believes LDI performance benchmarks should reflect each plan sponsor’s specific investment goals and objectives. To that end, we have developed a customization methodology that we believe will enable sponsors to align their fixed income allocations and their LDI objectives with far greater precision than either standard market benchmarks or more specialized duration-targeted or compound indexes.

Customized benchmarks also should allow sponsors to provide investment managers with more precise mandates and allow more granular performance attribution for both plan assets and plan liabilities.
