Calculation of the initial capital is one of the primary requirements in the feasibility study of industrial projects. In this paper a typical processing plant has been designed for the feed capacity of 500 to 8000 tons per day in sixteen different steps. A mathematical model in the form of Y=exp( a+b.Ln(X)) has been devised that calculates the cost of some of the machines used in these different capacity plants. In all these models Y is the capital cost and X is the most important variable in choosing the machinery. The total capital cost of all these different capacity plants have been calculated by adding the construction make, building etc to the results obtained from these models. A mathematical model is then introduced tllat calculates the total initial capital requirement for sixteen different capacity lead and zinc processing plants. The methods adopted and the models introduced could be used in the design process of such plants and to evaluate the feasibility of such project

This paper focuses on a comparison between lease and purchase while analyzing the effective features in making a decision on and selecting each. To do this, elements like cash outlay, the risk of absolescene, the abolition of lease and the possibility of cash allocation for profitable uses are dealt with. Besides, to present a concise comparison, different alternatives of purchase such as financing through borrowing and financing by means of installment sale are explained and exemplified by conditional sales and chattel mortgage, respectively. Cash circulation, tax factor, the omission of operations expenses, scrap and present values, as well as relevant problems in lease and purchase are also discussed.

The objective of this study is to evaluate changes in the level of cash holdings in response to corporates’ cash flows. For this, using financial information of a sample consisting of 118 companies listed in the Tehran Stock Exchange in the period 2006-2011, the sensitivity of cash flows of cash holdings was studied, regarding three aspects of: cash flows types (positive or negative), financial constraints, and external monitoring. This study is an applied research and takes regression method of panel data to test hypotheses.The findings showed that there was no difference in the cash flow sensitivity of cash in the two cases that companies face with a positive or a negative cash flows. Also, there was no difference between the cash flow sensitivity of cash in the cases of financially constrained and financially unconstrained. Additionally the findings showed that for the companies with stronger external monitoring the cash flow sensitivity of cash was not greater than that for the other companies.

The main purpose of this paper is to investigate the relationship between managerial overconfidence with firm cash holding and also examine the effect of managerial overconfidence on the changes in the level of cash holdings in response to corporates’ cash flows (cash-flow sensitivity of cash) using a sample of 127 (762 firm - year observations) firm listed on Tehran stock exchange between 2010 to 2015. The panel data was used to test the hypothesis. The findings of this research indicates a positive significant relationship between the managerial overconfidence with cash holding. Also findings show that managerial overconfidence have significant positive effect on cash-flow sensitivity of cash. In other words, overconfidence manager save more cash out of their current cash flow. These findings in accordance with the idea that overconfidence managers views future external financing as excessively costly and try to hold more cash for financing investment projects.

Effect of method of providing cash flow resulting from operating activities (direct and indirect methods) in power of predict future cash flows of the issues that a lot of research has led the financial literature. Cash Flow Statements aim to provide information regarding the flow of incoming and outgoing cash during an accounting period. If the flow of funds that offers with information on other users of financial statements should assist in these purposes to: (a) evaluate the company can create a positive future net cash flow evaluate the ability to participate in the confrontation commitments and also requires the company to external financing, evaluate the company can pay the financing costs and dividends, Children understand the difference and net operating profit company operating cash flows, determine the effects of capital transactions Investment and Financing made during the company' s financial condition. The aim of this paper is a review of this issue 1) directly compared the methods of indirect methods of calculating flow. Operating cash flow ability to predict more are operating? 2) whether operating cash flow compared with its components is more useful for investors.According to survey results with data collected from companies listed in Tehran Stock Exchange during the period 1380 until 1388 showed that the cash flow of information due to operational activities of the direct method predict more compared with indirect methods are entitled, and operating cash flow compared with its components is more useful for investors.
