Introduction Decision making is a rather important branch of every company. It goes without saying that a business company must pay special attention to the ways in which decisions are made and to the motivation of these decisions in this company. Decision making predetermines the general image of the company, and what is more important, the effectiveness of its work. That is why decision making should be developed and studied by the managerial staff of every company. Due to the same fact, decision making and its motivations are widely studied by various scholars. This paper is going to present major theories as to the motivations of ethical decision making in business companies and discuss them with the proper attention. Special attention will be paid to the ethics and deliberative opportunities for making decisions in business companies. Egoism vs. Altruism The most widely spread and traditional concept that is developed to explain the motivations of decisions in business companies is the dichotomy of egoism and altruism. The essence of the dichotomy lies in the fact that decisions and their desired effects are motivated by personal benefit, i. e. egoistic interest, of the person who makes this or that decision, or on the contrary the altruistic dedication to work when the benefit of the company is set before the personal benefit. But such a theory is rather biased and does not reflect the actual, or desired, state of things in ambitious companies. Every company that aims at developing and being successful must have the deliberative process as the basis of its work. Thus, the egoism or altruism model is not sufficient here. And to explain the relations of decision making in this or that company another model was created – multiple motives model that support deliberation and consideration of the overall company’s interests. Multiple Motives Model The essence of this very model lies in the fact that it presupposes the existence of deliberative activities in a company that allow making proper and well-motivated decisions. Besides, this model presupposes that the decisions made are motivated by multiple interests and benefits and satisfy the requirements of each member of this company. For example, a decision in a business company that touches upon the cutting of staff can not be considered ethical if it is made without deliberative procedures with the staff. If it is made by managers or executive officers of the company, than the multiple motivation is absent and company’s code of ethics needs considerable improvements. If such a decision is a result of deliberative meeting of all the employees and managers than the ethics is kept to and this is the decision making by means of multiple motives model that includes interests of managerial staff, ordinary employees and company’s customers who may also be affected by such step. Motivation Dynamic Deliberative process that takes place under implementation of multiple motives model has to subsequent steps that follow as given below:  1. Step one is presented by the “because” reasons, i. e. actual reasons that motivate this or that decision. Thus, for example, short supply of money can be a “because” reason that will motivate the decision of cutting
