1. 056How would you actually match a liability stream with a bond portfolio?Fixed income and LDIHardsuperdayFixed incomePension and endowment investing

   Say this

   Three approaches, increasingly approximate. Cash flow matching buys bonds whose coupons and maturities fund each payment, which removes reinvestment risk entirely. Immunisation matches duration and present value. Duration matching on a single number is the crudest, and it only works for parallel curve shifts.

   Then walk it

   1. Cash flow matching, sometimes called dedication: build a ladder so each year's payments are met by maturing principal and coupons. It is the cleanest hedge and needs no rebalancing, but it needs bonds at every maturity, which does not exist beyond 30 years in most markets, and it is expensive.
   2. Immunisation: match present value and duration, and make sure asset convexity is at least as high as liability convexity. Then a small parallel shift leaves the surplus unchanged. It needs rebalancing because durations drift at different speeds as time passes and yields move.
   3. The gap between them is the curve. A liability with 18 years of duration can be matched by a bullet at 18 years or a barbell of 5s and 30s. Same duration, very different behaviour if the curve steepens, so I would match key-rate durations at several points rather than one summary number.
   4. Then the parts you cannot match with bonds. Longevity risk, inflation beyond the index-linked market's capacity, and any real return requirement if the scheme is in deficit. That residual is what the return-seeking portfolio and, increasingly, a longevity swap or buy-in exists to cover.
   5. Practically, most schemes do it synthetically: physical bonds for the core, plus swaps or gilt repo to extend duration to 20 or 25 years without tying up all the capital, which leaves assets free for the growth portfolio.
   6. And then the operational governance: a collateral schedule, eligible collateral, a liquidity waterfall, and a stress test asking what a 150 basis point yield rise does to collateral calls over a week. That is the part that failed in 2022, and I would present it as part of the matching design rather than an afterthought.

   Where candidates lose it

   Saying 'match the duration' and stopping. Duration matching only immunises against a parallel shift, and real liabilities are exposed to the shape of the curve, so key-rate duration matching is the expected refinement. Also name what bonds cannot hedge, longevity and the deficit, because a candidate who thinks the liability can be fully hedged has not met a real scheme.

2. 058You are assessing exposure to EMEA real estate debt across the portfolio as eurozone rates shift. How would you judge attractiveness and which risk factors would you prioritise?Fixed income and LDIHardcase studyPIMCOReal Estate · Munich · 2024

   Say this

   Judge it on spread per unit of attachment risk, not on headline yield. The two numbers I would lead with are loan to value against a marked-down, not appraised, collateral value, and the debt yield, net operating income over loan amount, because that is the one metric that does not depend on a cap rate assumption.

   Then walk it

   1. Attractiveness framework: all-in yield equals the base rate plus spread, so first split how much of the return is just Euribor. If two thirds of a 9 percent coupon is the base rate, you are being paid 300 basis points for real estate credit risk, and that should be compared to corporate high yield at similar rating, not to the 2021 version of itself.
   2. Then the structural position. Senior versus mezzanine versus whole loan, and the attachment point. Senior at 55 percent LTV on a re-marked value is a genuinely different asset from mezzanine at 60 to 75 percent, and in a market where values have fallen 20 to 30 percent the second one may already be impaired.
   3. Prioritised risk factor one, refinancing and the maturity wall. European CRE loans written at 1 percent base rates and 60 percent LTV now face refinancing at 3 to 4 percent with lower valuations, so the borrower has a funding gap. That gap, not tenant default, is the source of most losses.
   4. Factor two, valuation lag. Appraisal-based values move slowly and transaction evidence is thin in a frozen market, so I would triangulate with listed REIT implied cap rates and with actual completed transactions, and underwrite to that rather than to the last valuation report.
   5. Factor three, debt yield and interest coverage at current rates. An ICR that was 2.5 times at origination on a floating loan can be below 1.2 now, which is where covenant breaches and cash traps start.
   6. Factor four, the collateral's own quality: sector, obsolescence and capex requirement, particularly energy performance rules in Germany and the Netherlands, which can strand an asset. Then jurisdiction, because enforcement timelines vary enormously across EMEA and a two-year workout in one country is a six-month process in another.
   7. The conclusion I would give: senior EMEA real estate debt at conservative LTVs on re-marked values is attractive because banks have retreated and the spread reflects illiquidity more than credit, while subordinate positions on 2021 valuations are where I would expect the losses.

   Where candidates lose it

   Answering with a rates view and a yield number. The interviewer wants credit underwriting at the loan level: attachment point, debt yield, interest coverage at today's base rate, and the refinancing gap. Quoting appraisal LTVs without re-marking the collateral is the mistake that made 2023 painful for a lot of real estate credit books.

   • Why do you prefer debt yield to LTV?
   • How would you re-mark a German office valuation?
   • Where in the capital structure would you actually invest?
