2.IBMpurchasedcomputerchipsfromNEC,aJapaneseelectronicsconcern,andwasbilled¥250millionpayableinthreemonths.Currently,thespotexchangerateis¥105/$andthethree-monthforwardrateis¥100/$.Thethree-monthmoneymarketinterestrateis8percentperannumintheU.S.and7percentperannuminJapan.ThemanagementofIBMdecidedtousethemoneymarkethedgetodealwiththisyenaccountpayable.

（a）Explaintheprocessofamoneymarkethedgeandcomputethedollarcostofmeetingtheyenobligation.

（b）Conductthecashflowanalysisofthemoneymarkethedge.

Solution:

（a）.Let’sfirstcomputethePVof¥250million,.,

250m/=¥245,700,

SoiftheaboveyenamountisinvestedtodayattheJapaneseinterestrateforthreemonths,thematurityvaluewillbeexactlyequalto¥25millionwhichistheamountofpayable.

Tobuytheaboveyenamounttoday,itwillcost:

$2,340,=¥250,000,000/105.

Thedollarcostofmeetingthisyenobligationis$2,340,asoftoday.

（d）IllustratethefuturedollarcostsofmeetingtheSFpayableagainstthefuturespotexchangerateunderboththeoptionsandforwardmarkethedges.

Solution:

（a）Totaloptionpremium=（.05）（5000）=$250.Inthreemonths,$250isworth$=$250.Attheexpectedfuturespotrateof$SF,whichislessthantheexerciseprice,youdon’texpecttoexerciseoptions.Rather,youexpecttobuySwissfrancat$SF.SinceyouaregoingtobuySF5,000,youexpecttospend$3,150（=.63x5,000）.Thus,thetotalexpectedcostofbuyingSF5,000willbethesumof$3,150and$,.,$3,.

（b）$3,150=（.63）（5,000）.

（c）$3,150=5,000x+,wherexrepresentsthebreak-evenfuturespotrate.Solvingforx,weobtainx=$SF.Notethatatthebreak-evenfuturespotrate,optionswillnotbeexercised.
