Resumen
our simulations of the surface mass balance (SMB) of the Greenland ice sheet (GrIS) are compared over the period 1960-2008. Three use a regional climate model to downscale ECMWF reanalysis (ERA-40) and operational analysis data, while the fourth uses the same inputs but an empirical downscaling approach and melt model. These reconstructions have been used in a variety of applications but prior to this study little was known about their consistency with each other and the impact of the downscaling method on the result. The reconstructions are compared to assess the consistency in regional, seasonal and integrated 5MB components and evaluated against a suite of observational data. Three key areas of difference between the models have been identified. Firstly differences in how the ERA-40 reanalysis data are downscaled by the models. Secondly differences in how the 5MB components are calculated. And thirdly differences in the domain, the ice sheet mask used. Total 5MB estimates for the GrIS are in agreement within 34% of the four-model average when a common ice sheet mask is used. When models' native land/ice/sea masks are used this spread increases to 57%. The components of 5MB, with the exception of refreeze, show a similar level of agreement once a common mask is used. Previously noted differences in the models I estimates are partially explained by ice sheet mask differences. Agreement is higher (18% spread) in the accumulation area than the ablation area (38% spread) suggesting relatively high uncertainty in the estimation of ablation processes. Regionally there is less agreement, suggesting spatially compensating errors improve the integrated estimates. Modelled 5MB estimates are compared with in situ observations, gravimetric observations from GRACE and altimetry observations from ICESat. Through the use of a surface density and firn compaction model individual components of 5MB are, indirectly, able to be evaluated against altimetry observation.

Resumen
In order to improve our knowledge on the current state and variability of the Greenland ice sheet surface mass balance (SMB), a 27-year simulation (1979-2005) has been performed with the coupled atmosphere-snow regional model MAR. This simulation reveals an increase in the main factors of the SMB which are, on the one hand, the snowfall (+ 1.6 ± 1.8 km3 yr-1) in winter and on the other hand, the run-off (+ 4.2 ± 1.9 km3 yr-1) in summer. The net effect of these two competing factors leads to a SMB loss rate of – 2.7 ± 3.0 km3 yr-1, which has a significance of 87%. The melt extent derived from the passive microwave satellite data since 1979 also shows this trend. The melt water supply has increased because the Greenland ice sheet has been warming up by + 0.09 ± 0.04 °C yr-1 since 1979. This warming comes from a uniform increase of downward infra-red radiation which can not be explained by the natural variability. These changes result very likely from the global warming induced by human activities. As a result, it seems that: i) increased melting dominates over increased accumulation in a warming scenario, ii) the Greenland ice sheet has been significantly losing mass since the beginning of the 1980's by an increasing melt water run-off as well as by a probable increase of iceberg discharge into the ocean due to the "Zwally effect" (the melt water-induced ice sheet flow acceleration) and iii) the Greenland ice sheet is projected to continue to lose mass in the future. The Greenland ice sheet melting could have an effect on the stability of the thermohaline circulation (THC) and the global sea level rise. On the one hand, increases in the freshwater flux from the Greenland ice sheet (glacier discharge and run-off) could perturb the THC by reducing the density contrast driving it. On the other hand, the melting of the whole Greenland ice sheet would account for a global mean sea level rise of 7.4 m.

Resumen
Die zentralen Fragestellungen der Arbeit sind, wie die Insolvenzwahrscheinlichkeiten von Unternehmen prognostiziert und wie sie durch zielgerichtetes Handeln beeinflusst werden können. Hierzu gibt der Autor zunächst einen ausführlichen Überblick über die derzeit in Wissenschaft und Praxis verwendeten Ansätze zur Prognose von Unternehmensinsolvenzen, Schätzgütemaßen von Insolvenzprognosen sowie Datenquellen, die für die Prognose von Unternehmensinsolvenzen zur Verfügung stehen. Anschließend entwickelt er ein kausales Unternehmensmodell, das er mit stochastischen Simulationsverfahren analysiert. Das Modell wird validiert und mit Benchmarkverfahren verglichen. Abschließend zeigt der Autor, wie das Modell zur Ableitung von Handlungsempfehlungen zur Beeinflussung der individuellen Insolvenzwahrscheinlichkeit von Unternehmen herangezogen werden kann.

Resumen
Companiesissuing insurance cover, in return for insurance premiums, face the payments ofclaims occurring according to a loss distribution. Hence, capital must be heldby the companies so that they can guarantee the fulfilment of the claims ofeach line of insurance. The increased incidence of insurance insolvencymotivates the birth of new legislations as the European Solvency II Directive.Companies have to determine the required amount of capital and the optimalcapital allocation across the different lines of insurance in order to keep therisk of insolvency at an adequate level. The capital allocation problem may betreated in different ways, starting from the insurance company balance sheet.Here, the running process and efficiency of four methods are evaluated andcompared so as to point out the characteristics of each of the methods. TheValue-at-Risk technique is straightforward and can be easily generated for anyloss distribution. The insolvency put option principle is easily implementableand is sensitive to the degree of default. The capital asset pricing model isone of the oldest reliable methods and still provides very helpful intermediateresults. The Myers and Read marginal capital allocation approach encouragesdiversification and introduces the concept of default value. Applications ofthe four methods to some fictive and real insurance companies are provided. Thethesis further analyses the sensitivity of those methods to changes in the economiccontext and comments how insurance companies can anticipate those changes.

Resumen
In the late 1990s and early 2000s several revenue recognition scandals arose, which led to a discussion about the need for a new principle-based standard with a balance sheet-based approach for revenue recognition. On 1st of January 2018 IFRS 15 Revenue from Contracts with Customers became effective and replaced all previous revenue recognition standards and interpretations. All companies are expected to be affected regarding when and how much the company reports its revenue, though the scope may vary from one company to another. This study aims to investigate how the application of IFRS 15 has impacted companies based on the business models they apply in their customer agreements. To operationalize the purpose of the study a quantitative method was adopted to gather the empirical data, which have been obtained from the companies’ annual reports. An enumeration was implemented, why all listed companies on Nasdaq Stockholm which are required to implement IFRS 15 have been studied. The results indicate that a minority of the companies have showed an impact and most of the companies have not been impacted after an implementation of the new revenue recognition standard. The study has identified that the reason why companies are affected by IFRS 15 depends on the business models’ companies apply in their customer agreements. The minority of companies that have been affected by IFRS 15 are the ones which have developed business models that includes complex customer contracts, i.e. customer contracts consisting of complex commitments and promises of goods and services to customers. Accordingly, the majority of the studied companies uses business models with non-complex customer contracts in their customer agreements, e.g. simple sale of only one good, hence their revenue recognition under IFRS 15 does not differ from previous accounting standards.
