嗨，努力学习的PZer你好：
”这道题不需要考虑denominated in dollars 排除benchmark 3吗？”
也可以用货币排除。这道题Benchmark 3因为直接用Duration就排除掉了，所以还没用上货币这个信息。
假设Benchmark 3的条件和Benchmark 2的条件一模一样，也是由中期、短期的指数混合而成，唯一区别就是Benchmark 3有一个货币是EUR，那我们就可以利用货币直接排除Benchmark 3。

Molly, chief investment officer, is meeting with a prospectiveclient, Leof Puy FinanciCompany (C). Leahinforms Molly thC’s previous fixeincome manager focuseon the interestrate sensitivities of assets anliabilities when making asset allocationcisions. Molly explains that, in contrast, SR’s investment process firstanalyzes the size antiming of client liabilities, anthen it buil assetportfolio baseon the interest rate sensitivity of those liabilities. Mollynotes thSR generally uses actively manageportfolios signeto earna return in excess of the benchmark portfolio. For clients interesteinpassive exposure to fixeincome instruments, SR offers two aitionalapproaches.Approa1: Seeks to fully replicate a small range of benchmarks consisting of government bon.Approa2: Follows enhanceinxing process for a subset of the bon incluin the Bloomberg Barclays US Aggregate BonInx.

Leexpresses concern aboutthe risks associatewith immunization strategy for this obligation. Inresponse, Molly makes the following statements about liability-iveninvesting:Statement 1: Although the amount ante of SR’s liability is known with certainty, measurement errors associatewith key parameters relative to interest rate changes maersely affethe bonportfolios.Statement 2: A cash flow matching strategy will mitigate the risk from non-parallel shifts in the yielcurve.Mollyprovis the four US llar–nominatebonportfolios in Exhibit 1 forconsiration. Molly explains ththe portfolios consist of non-callable,investment-gra corporate angovernment bon of various maturities becausezero-coupon bon are unavailable.The scussion turns to benchmarkselection. C’s previous fixeincome manager usea custom benchmark with thefollowing characteristics:Characteristic 1: The benchmark portfolio invests only in investment-gra bon of US corporations with a minimum issuansize of $250 million.Characteristic 2: Valuation occurs on a weekly basis, because many of the bon in the inx are valueweekly.Characteristic 3: Historicprices anportfolio turnover are available for review.Mollyexplains that, in orr to evaluate the asset allocation process, fixeincomeportfolios shoulhave appropriate benchmark.
