BakgrundVD-yrket sägs ha blivit en allt mer utsatt position. I spåren av denna utveckling kan det te sig rimligt att nytillträdda VD:ar vill ge sig själva en god start på den aktuella tjänsten. Inom akademins värld anses en VD-förändring vara den situation där resultatmanipulering genom Big Bath är främst förekommande. Vi frågar oss dock om detta är en produkt av tidigare forskning selektionsmekanism och om Big Bath påverkas mer av andra faktorer. SyfteStudiens syfte är att undersöka Big Bath från en bredare tidshorisont som inte isolerar enskilda händelser. På så sätt vi vill undersöka om VD-förändringar är den situation som starkast påverkar Big Bath. MetodGenom användning av en longitudinell panelstudie med en deduktiv ansats har studien undersökt hur resultatmanipulering och Big Bath påverkas av olika faktorer däribland VD-byten. Urvalet består av bolag från NASDAQ OMX Stockholm Large Cap under åren 2006-2017. SlutsatsResultatet visar att VD-byten inte har någon signifikant påverkan på varken resultatmanipulering eller Big Bath. I studien fann vi dock indikationer på att negativa resultat påverkar förekomsten av både resultatmanipulering och Big Bath. / BackgroundThe CEO-profession is said to be more precarious than ever before. Given this development one can assume that newly appointed CEO’s are interested in securing a good start at the beginning of their appointment. In the academic world a CEO turnover is considered to be the primary situation were earnings management in the form of Big Bath occurs. We ask ourselves if this is a product of previous selection bias and if Big Bath in true is affected by other factors. PurposeThe purpose of this study is to examine Big Bath from a long-term perspective that does not isolate specific events. Through this approach we want to investigate whether CEO-turnovers is the main contributing factor behind Big Bath. MethodBy using a longitudinal panel study with a deductive approach the study have investigated how earnings management and Big Bath are affected by different factors such as CEO-turnovers. The sample consists of companies from NASDAQ OMX Stockholm Large Cap in between the time period of 2006-2017.ConclusionThe result states that CEO-turnovers have no significant effect on either earnings management or Big Bath. However through the study we find indications that negative results affects both earnings management and Big Bath.

Den här uppsatsen undersöker hur aktiekursen reagerar när bolag offentliggör information angående ett VD-byte. Studien undersöker både frivilliga uppsägningar och avsked av VD:n på bolag noterade på Stockholmsbörsen mellan år 2011 och 2018. För att kunna undersöka aktiekursens reaktion har MacKinlays form av eventstudie tillämpats på 90 bolag. Bolags aktiekurs tenderar att reagera negativt vid ett tillkännagivande angående ett byte av verkställande direktör. Studien finner signifikanta resultat beroende på om bytet varit frivillig uppsägning eller avsked under eventdagen. Undersökningen påvisar signifikanta resultat på aktiekursen när investerare haft kännedom om ersättare och om tillkännagivandet skett innan ett byte. / This paper examines how the share price responds when companies publish information regarding a change of CEO. All the companies that are examined are listed on the Stockholm Stock Exchange between 2011 and 2018. The study is based on a sample of 90 companies where the CEO has been replaced. Of the entire sample there has been 65 voluntary CEO´s changes and 25 involuntary. To investigate how the share price react we use MacKinlays (1997) form of event study. This study also examines how different factors effect the reaction of the share price. These factors are; the availability of a successors, the size of the firm, the time interval between the event day and the day the CEO leaves the company. We find that the market tends to react negatively at the event day. We also find a significant difference between voluntary and involuntary change of CEO a few days after the event. The involuntary change of CEO´s tends to give a positive market reaction and the voluntary a continued negative market reaction. When companies announce a change of CEO simultaneously as they announce successors the market tends to react positively.

Purpose: The purpose with this work has been to investigate and map selected fireprotection methods in a number of projects. The possibilities and limitations with exposedCLT have been investigated. Method: The method consists of a literature study, interviewstudy, construction site visit and survey. The literature study has been carried out with theaim of presenting relevant facts to the subject and creating a basis for the interview study.The interviews were conducted with fire consultants for the work´s investigated projects.Two of the projects also included construction site visit, of which one of the projects belongsto the partner of this work, Peab. During the visits of the construction sites a tour of thebuilding were carried out and shown where the exposed CLT was placed. The results from theinterviews and construction sites visits are the basis for the survey. Results: The resultsshow that analytical dimension of the fire protection is required when constructing multistory residence with internally exposed CLT. Limitations with exposed CLT are due, amongother things, to the fact that untreated wood does not fulfils the requirements set in BBR forthe surface layer. Delamination contributes to increased fire load as the underlaying slats areexposed to fire. The current study contains two projects carried out with exposed CLT,Notuddsparken and ETC apartment buildings. The projects have dimensioned each withanalytical dimension but with different fire protection methods. Notuddsparken has beenconstructed with automatic sprinkler systems and the ETC apartment buildings have beenconstructed with fire protection impregnation of the exposed CLT. Conclusions:Conclusions established in the work shows that when using exposed CLT analyticaldimension of the fire protection is required. Most of the fire consultants in this work haveexpressed that they do not feel comfortable with dimensioning fire protection for buildingswith exposed CLT, based on the current state of knowledge.
