ongoing payouts, and thereby limit cash accumulation, comes via the firm’s stock price, which investors will discount if they believe retention is excessive. Such discounting both reduces the value of managers’ personal equity stakes and raises the probability of a takeover, both of which make managers worse off.3 A given dollar payout to debt or equity generates the same reduction in internal resources, thus the same reduction in managerial wastage of resources and the same increase in stockholders’

Let’’s back up slightly & see where this equipartition law ( Boltzmann distribution (for energies of harmonic oscillators): general result from classical statistical mechanics (see Appendix C) = kT )comes from: P( ) e kT kT P( )d is probability of finding an oscillator with energy in +d So, knowing P( ), how do we calculate ?

atmospheric modeling of ExternE. Experts have been asked to evaluate the approach taken by ExternE. Upper and lower bounds on the calculations of the dispersion module have been established by means of a Monte Carlo analysis, taking into account the probability distributions of the uncertain input parameters. EcoSense calculations have been compared with a recent and more detailed model, and for a few cases where measured data were available, they have been compared with EcoSense calculations; in all cases

reduced, and failure to take such an approach will inevitably lead to a less than satisfactory outcome. This chapter discusses various aspects of the project environment, and suggests ways in which it may be influenced in order to increase the probability of a successful outcome. Introduction Why worry about the project environment, when the objective of project management is to get the project completed within scope, cost and schedule? The truth is that if the real objective is to end up with a

case of dispute, that is to say issues relating to the capacity and authority of the Borrower to enter into agreement and the validity of agreement as regard to its formation. Basically, when the counselor or the law firm has to determine the probability of risk of non-performance or ill- performance of the transaction as regard to the statute of the borrower, he focuses his attention on the fact to know whether the borrower is duly incorporated, has a valid existence, qualification to do business

pertes économiques éventuelles subies sur un portefeuille de crédit. Dans ce cadre, le calcul des exigences en fonds propres pour le risque de crédit encouru sur un prêt se base sur les paramètres suivants: la probabilité de défaut de l'emprunteur ("probability of default"); L'exposition au moment du défaut ("exposure at defaut"EAD), Elle correspond au montant dû par la contrepartie au moment où elle fera défaut sur un engagement donné la perte en cas de défaut ("loss given default"), c'est-à-dire le
