Thisstudyfocusesontherelationbetweenthestructureofexecutivecompensationandincentivestomanagereportedearnings.Specifically,weexaminewhethertheuseofstockoptionsrelativetootherformsofpayinfluencesdiscretionaryaccrualchoicesaroundoptionawarddates.Weconductthisstudyinpartbecauseoftheapparenttrendoverthepasttwodecadestowardtheuseofoptionsinexecutivepay.Compensationresearchhasconsistentlyshownthatoptionawards,measuredonafairvaluebasis,nowrepresentonaveragethelargestcomponentofCEOpay（Murphy[1999];Baker[1999];Matsunaga[1995];Yermack[1995]）.Notsurprisingly,thistrendseemstohavecontributedtoincreasedscrutinyofCEOpayandtohaveleddirectlytoseveralpublicpolicyinitiativesduringthe1990s.Forexample,accountingstandardsettersadoptedaseriesofrulesthatgreatlyexpandedinvestorreportingrequirementsonoptions（SEC[1992,1993];FASB[1995]）,and,in1993,Congressenactedtaxlegislationintendedtocurbnonperformance-basedexecutivepay（seeReitengaetal.[2002];PerryandZenner[2001]）.Furthermore,asreportedinthefinancialpress,criticismofthemagnitudeofoptionawards,includingcriticismbyinvestors,seemstooccurregularly（e.g.Orwall[1997];Jereski[1997];Fox[2001];Colvin[2001]）.Standardsettersandpoliticiansarecurrentlyreexaminingdisclosurerules,offeringevidencethatoptionscontinuetobeadifficultpublicpolicyissue（Schroeder[2001];HamburgerandWhelan[2002];WSJ[2002]）.

Untilrecently,academicresearchhastypicallyfocusedontestingtheuseofoptionswithinanagencytheoryframework,primarilyexaminingincentivealignmentaspects.Arguably,bytyingexecutivepaytostockpriceoutcomes,optionsencouragemanagerstomakeoperatingandinvestingdecisionsthatmaximizeshareholderwealth（JensenandMeckling[1976]）.Thoughresultsaremixed,theempiricalevidenceonoptionsasacomponentofexecutivepayhasgenerallysupportedsuchagency-basedpredictions.However,otherstudiesdocumentunexpectedeffectsonthefirmaswell,includingsurprisingevidencethatawardingoptionscaninduceopportunisticbehaviorbymanagement.Thelineofresearchmostrelevantforourstudyisonethatsuggeststhatmanagersmanipulatethetimingofnewsreleasesoroptionawarddates（orboth）asameansofincreasingthefairvalueoftheirawards.Forexample,AboodyandKasznik（2000）reportevidenceindicatingthatmanagerstimethereleaseofvoluntarydisclosures,bothgoodandbadnews,aroundawarddatesinordertoincreasethevalueoftheoptionsawarded.Sincetheexercisepriceoftheoptionistypicallysetequaltothesharepriceonawarddate,managerscanconceivablyincreasetheiroptioncompensationbyreleasingbadnewsbeforetheawarddate.Consistentwiththisreasoning,ChauvinandShenoy（2001）findthatstockpricestendtodecreasepriortooptiongrants,whileYermack（1997）findsthatstockpricestendtoincreasefollowingoptiongrants.Theformereffectwouldtypicallydecreasetheexercisepriceoftheoptionatawarddate.Thelatterwouldincreasetheoption'sintrinsicvalueafterward.

Therestofourpaperisstructuredasfollows.InSection2,wedevelopourresearchhypotheses.Section3describesourresearchdesign,andSection4presentsourmainresultsanddetailsonsensitivitytests.Finally,Section5discussestheseresultsandtheirimplicationsforexecutivecompensationpractices.

Basedonpreviousstudiesandourownreviewofproxystatements,itappearsthattheprocessofawardingoptionsfollowsastandardpattern（Yermack[1997];AboodyandKasznik[2000]）.Awardsareformallydeterminedbyacompensationcommitteeoftheboardofdirectorsandarenearlyalwaysmadeonceperyear,typicallywithanexercisepriceequaltosharepriceonawarddate.

Asnotedintheintroduction,mostoftheacademicresearchontheuseofstockoptionshasusedanagencytheoryframework,approachingthestructureofexecutivepayasasolutiontovariousagencyproblems.EarlyresearchsuchasDeFuscoetal.（1990）andYermack（1995）yieldedmixedresults,leavingsignificantunansweredquestionsabouttheprevalenceofoptions.Perhapsbecauseofbetterdataavailability,recentagency-basedresearchhasprovidedmoreconsistentresults.Forexample,studiesbyCoreetal.（1999）,CoreandGuay（1999）,andBryanetal.（2000）appeartosupportthetheorythatexecutivepaystructureingeneral,andtheuseofoptionsinparticular,reflectsfirms'agencycosts.

However,otherlinesofresearchonoptionsindicatethatexecutivecompensationpracticescouldproduceunintendedconsequencesforthefirm.Forexample,Lambertetal.（1989）findthatfirmsexhibitlowerthanpredicteddividendpaymentlevelsafteradoptingexecutivestockoptionplans.Becausethepayoffonanoptionisdeterminedbystockpriceappreciationratherthantotalshareholderreturn（appreciationplusdividends）,dividendreductionincreasesoptionvalue.Whileapparentlygoodforoption-holdingexecutives,suchadividendpolicymightnotbefullyanticipatedby,orinthebestinterestsof,shareholders.Pursuingasimilarargument,Jolls（1996）findsthatstockrepurchasestendtoreplacecashdividendsasexecutiveoptionholdingsincrease.Inaddition,thelineofresearchthatweextenddocumentsthatmanipulationofvoluntarydisclosuresand/orawarddatescouldincreasethevalueofoptioncompensation.Takentogether,theevidencesuggeststhatwhileoptioncompensationpracticesarelikelytomitigatesometypesofagencycosts,thesamepracticesmightinduceotherformsofopportunisticbehavior.Wediscussthesefindingsinmoredetailalongwithotherrelevantresearchonearningsmanagementbelow.

Priorresearchsuggeststhatmanagersmanipulateearningstoachieveavarietyofobjectives,including"incomesmoothing"（Gaveretal.[1995];DeFondandPark[1997]）,long-termbonusmaximization（Healy[1985]）,avoidanceoftechnicaldefaultofdebtcovenants（DichevandSkinner[2001]）,andavoidanceoflossesanddeclinesinearnings（BurgstahlerandDichev[1997]）.Murphy（1999）suggeststhatoptioncompensationandoutrightstockownershipbymanagersgiverisetodivergentincentives,withstockownershipfocusingmanagers'effortsonachievinghighertotalshareholderreturnsandoptionsrewardingonlysharepriceappreciationrelativetotheexerciseprice.Severalempiricalstudiesprovidesupportforthesepredictions（Lambertetal.[1989];Lewellenetal.[1987]）.Weconjecturethatthesedivergentincentivescouldmotivatemanagerstomanipulateearningsupordownasafunctionofcompensationstructureandotherfactors.

Asanexample,Matsunaga（1995）arguesthat,whenfirmsareunderfinancialdistress,theyattempttoreducecompensationexpensebysubstitutingoptionsforbonuspay.Matsunagaalsofindsthatincome-increasingaccountingpolicychoicesarepositivelyrelatedtooptionawards.Byextension,thisresultcouldimplyapositiverelationbetweenincome-increasingdiscretionaryaccrualsandoptioncompensation.However,Matsunagaexaminesonlytheassociationsbetweenoptionsandvariousfinancialcharacteristicsofthefirm,andhisanalysisdoesnotdirectlyexamineanyearningsmanagementincentivesrelatedtooptioncompensation.
