Also, a parallel shift in yielcurves is a sufficient but not anecessary contion to achieve the sireoutcome. Non-parallel shifts welltwists in the yielcurve cchange the cash flow yielon the immunizingportfolio; however, minimizing the spersion of cash flows in the assetportfolio mitigates this risk. a result, both statements are correct. 这一题是matsingle liability。那么在portfolio里直接买9年到期的zero coupon bon可以matsingle liability并且不会受利率风险的影响了。那么statement1就是错的了。但是答案说statement1是对的，请问这点怎么理解？

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.
