Leasinggeschäfte in der Handels- und Steuerbilanz

Leasinggeschäfte haben im Verlauf der letzten zwei Jahrzehnte stark an Bedeutung gewonnen. Ihre Behandlung in der Handels- und Steuerbilanz ist jedoch bisher noch nicht eindeutig geklärt. Harald Helmschrott untersucht Aspekte der bilanziellen Behandlung unter besonderer Berücksichtigung der Zurechnung des Leasingobjektes.

Wem dient der Auswärtige Dienst?: Erfahrungen von Politik, Wirtschaft, Gesellschaft

In dem Band diskutieren namhafte Autoren aus Gesellschaft, Wissenschaft und Politik über die künftigen Aufgaben und Anforderungen an den deutschen Diplomatischen Dienst. Mit dem grundsätzlichen Wandel der internationalen Politik wandelt sich auch die Stellung der Bundesrepublik in ihr. Der Auswärtige Dienst hat eine wichtige Rolle bei der Meisterung der neuen Anforderungen, auch wenn der Bereich, der offiziell noch vom Auswärtigen Amt zu internationalen Fragen bearbeitet wird, stetig schmaler wird: Durch die europäische Integration, durch die Privatisierung vieler internationaler Beziehungen, durch die wirtschaftliche wie gesellschaftliche Globalisierung.

Die Entwicklung der Zinsstrukturkurve: Eine Analyse homogener affiner Mehrfaktormodelle auf Basis des Kalman-Filters

Kenntnisse über die Entwicklung der Zinssätze beliebiger Fristen der Zinsstrukturkurve sind essentiell für eine Vielzahl von Anwendungen. Beispielsweise für Fragen der Kapitalanlageprojektion, die im Asset/Liability-Management und im Rahmen der Gesamtunternehmenssteuerung von Relevanz sind, ist die Modellierung und Projektion der Wertentwicklung des Zinstitelbestands die zentrale Problemstellung.

32 D. H. 3 THE MOULD AND MOULDING As for all types of injection moulding, mould design and construction is a specialist field. 1 Mould Filling It is usual to fill the mould from its lowest point, by means of a full-width film gate, fed with large size runners, which must exceed the volume capacity of the gate, in order to maintain pressure. During mixing, as we have seen, the flow is on the point of becoming turbulent: laminar flow into the mould is required to avoid entrapment of air. This means the velocity of filling must be reduced, following mixing, a function filled by the runner system.

This approach is essential if delivery promises are to be kept and a high level of business is to be maintained (high level in terms of both the quality and quantity of work). By taking advantage of this type of facility, mouldmakers are saved the problems of investing in highly expensive equipment and are left free to concentrate on those parts of mouldmaking for which their personnel are better suited. g. milling, turning, grinding, drilling, boring, etc. These processes will be found to be well-treated in most engineering workshop manuals.

2 (a) (b) TERMINOLOGY Filament: individual length of glass formed by extrusion of molten glass through an orifice. Strand: a collection (bundle) of filaments. A strand often comprises several hundred filaments. INJECTION MOULDING DERIVATIVES (c) (d) (e) 27 Fibre: a general term used to denote a material in which the length to diameter ratio exceeds approximately 100. It could refer to either a filament or a strand. Aspect ratio: ratio of length to diameter. Critical fibre length: that length below which fibres with good matrix adhesion tend to pull out on part failure.
