Major role of the financial management is the selection of the most gainful assortment of capital investment and it is vital area of decision-making for the financial manger because any action taken by the manger in this area affects the working and the success of the firm. Capital budgeting is the planning process used to regulate whether an organization's long term investments such as new machinery, replacement machinery, new plants, new products, and research development projects are worth the funding of cash through the firm's capitalization structure (debt, equity or retained earnings). It is the procedure of allotting resources for major capital, or investment, expenditures (Sullivan, 2005). It is also stated by financial scholars that capital budgeting is the decision making process by which a firm appraises the purchase of major fixed assets including building, machinery and equipment.
Bulk of management literature explained the notion of the capital budgeting. Hamption, John specified that Capital budgeting is concerned with the firm's formal process for the acquisition and investment of capital. Several management experts have defined capital budgeting. Charles T. Homgreen elaborated that , "Capital Budgeting is long-term planning for making and financing proposed capital outlays." According to Richards and Greenlaw, "The capital budgeting generally refers to acquiring inputs and long-run returns." G. C. Philipattos stated that "Capital budgeting is concerned with the allocation of the firm's scarce financial resources among the available market opportunities. The consideration of investment opportunities involves the comparison of the expected future streams of earnings from a project; with the immediate and subsequent stream of expenditures for it."
According to Joel Dean, "Capital Budgeting is a kind of thinking that is necessary to design and carry through the systematic programme for investing stockholders' money. The idea of capital budgeting has an immense importance in project selection as it supports in planning capital required for completing long-term projects. Selection of a project is a major investment decision for an organization
The capital budgeting process can be successful if company determines the total capital expenditure for a project that is expected to generate returns over a particular period of time. An organization uses various methods to determine the total expenditure for a project and rate of return yielded from it. Some of the popular techniques are net present value, internal rate of return, payback period, sensitivity analysis, and decision tree analysis.
Prime goals of capital budgeting investments is to upturn the value of the firm to the shareholders. It has also an objective to rank projects and raise funds. Basically, the purpose of budgeting is to provide a forecast of revenues and expenditures and construct a model of how business might perform financially. It means to construct a model of how a business might perform financially if certain strategies, events, and plans are carried out. It empowers the actual financial operation of the business to be measured against the forecast, and it establishes the cost constraint for a project, program, or operation. Budgeting helps to aid the planning of actual operations by forcing managers to consider how the conditions might change, and what steps should be taken in such an event. It encourages managers to consider problems before they arise. It also helps co-ordinate the activities of the organization by compelling managers to examine relationships between their own operation and those of other departments.

Principles of Capital Budgeting Decisions:
A decision regarding investment or a capital budgeting decision involves the following principles:
The necessity of capital budgeting can be highlighted taking into consideration the nature of the capital expenditure such as heavy investment in capital projects, long-term implications for the firm, irretrievable decisions and complicates of the decision making. Its importance can be judged on the following other grounds:
Basically, the firm may be challenged with three types of capital budgeting decisions:
1. Initial Investment Outlay: It comprises of the cash necessary to obtain the new equipment or build the new plant less any net cash proceeds from the disposal of the replaced equipment. The initial outlay also includes any additional working capital related to the new equipment. Only changes that occur at the launch of the project are included as part of the initial investment outlay. Any additional working capital required or no longer needed in future period is accounted for as a cash outflow or cash inflow during that period.
Net Cash benefits or savings from the operations: This component is calculated as under.
(The incremental change in operating revenues minus the incremental change in the operating cost = Incremental net revenue) minus (taxes) plus or minus (changes in the working capital and other adjustments).
Terminal Cash flow: It consist of the net cash generated from the sale of the assets, tax effects from the termination of the asset and the release of net working capital.
The Net Present Value technique: The Net Present Value technique is common among all techniques used. Under this method, a project with a positive NPV suggests that it is worth investing in.
There are many phases of capital budgeting.
Phases of capital budgeting:

Some selection rules for both methods are as follows:
|
Non-discounting Criteria |
Accept |
Reject |
|
Payback Period (PBP) |
PBP < Target period |
PBP > Target period |
|
Accounting Rate of Return (ARR) |
ARR > Target Rate |
ARR < Target Rate |
|
Non-discounting Criteria |
Accept |
Reject |
|
Net Present Value (NPV) |
NPV > 0 |
NPV < 0 |
|
Internal Rate of Return (IRR) |
IRR > Cost of
capital |
IRR < Cost of
capital |
|
Benefit- Cost Ratio (BCR) |
BCR > 1 |
BCR < 1 |
4. Financing: After choosing a project, proper financing must be made. Equity and debt are two major sources of Finance for a project. Flexibility, risk, income, control and taxes are the vital business considerations that influence the capital structure decision and the choice of specific instruments of Financing.
5. Implementation: The implementation phase for an industrial project, which involves the establishing manufacturing facilities has several stages:
I. Project and engineering designs
II. Negotiations and contracting
III. Construction
IV. Training
V. Plant commissioning
6. Review: Once the project is commissioned, a review phase has to be done. Performance review should be done occasionally to compare the actual performance with the projected performance. In this stage, feedback is beneficial in several ways:
I. It focuses on realistic assumptions.
II. It provides experience, which will be valuable in future decision making.
III. It recommends corrective action.
IV. It supports to uncover judgmental biases.
V. It promotes the need for caution among project sponsors.
There are numerous appraisal methods which may be suggested to assess the capital investment proposals. Most widely accepted methods are grouped into the following categories:
I. Traditional Methods:
Traditional methods are further divided into the following:
(1) Pay-back period method or Pay-out method.
(2) Improvement of Traditional Approach to Pay-back Period Method.
(a) Post Pay-back profitability Method.
(b) Discounted Pay-back Period Method.
(c) Reciprocal Pay-back Period Method.
(3) Rate of Return Method or Accounting Rate of Return Method.
II. Time Adjusted Method or Discounted Cash Flow Method
Time Adjusted Method further classified into:
i. Net Present Value Method.
ii. Internal Rate of Return Method.
iii. Profitability Index Method.
Capital budgeting decisions are categorized into these three decision levels.
