Solution:Approaches or Methods of Human Resource Valuation: The accountants and finance professionals have suggested various methods for measuring the value of human resources utilized in an organisation.
They are:
1. Historical Cost Method: This method is developed by Rensis Likerst. Under this method, all actual costs incurred on recruitment, training, familiarisation, etc., are capitalized.
Then, the capitalized cost is amortised, or say, written off over the period an employee serves in the organisation.
In case the employee leaves the organisation before his expected service period, the remaining amount is written off completely in that particular year of his/her leaving the organisation.
The advantage of this method is that the value of human asset can be shown on conventional Balance Sheet and Profit and Loss Account. However, its drawback, if at all, is that human resource is equated resulting in undervaluation.
2. Replacement Cost Method: As the title itself indicates, under this method, replacement cost refers to the cost of replacing an existing employee. In other words, replacing cost is the cost that would cost to replace the existing human resources with human resources capable of rendering equivalent services.
Here, the underlying costs included in replacement cost are the cost of recruitment, training and development, opportunity cost for the intervening period till the new recruit attains the efficiency level equal to that of the old (to be replaced) employee.
In this way, this method helps the management in the process of human resource planning for the organisation by making the information available on costs to be involved in the acquisition of people in future. In a sense, this method is inconsistent with the 'historical cost method'.
That there may not be similar replacement cost for a certain asset and management may not be willing to replace the present human asset because of its greater value than that of scrap value are some of the drawbacks of this method.
3. Opportunity Cost Method: This method is used to value employees possessing certain skills and, thus, are rare in availability. Managers willing to acquire such scarce employees offer bid prices.
One who finally acquires the scarce employees puts the bid price as his investment in such employees. The bid price is arrived at calculating actual or expected rate for capitalisation of the supposed earnings to be earned by such employees.
Obviously, if an employee can be hired easily, there will be no opportunity cost for him/her. The main drawback of this method is the absence of a well justified criterion to decide the amount of the bid, or say, offer.
4. Asset Multiplier Method: This method is based on the assumption that there is no direct relationship between cost incurred on an employee and his value for the organisation.
This is because the value of an employee depends on factors like motivation, working conditions and their attitude toward work and organisation.
In this method, all employees working in an organisation are broadly classified into four categories; viz., top management, middle management, supervisory management and operative and clerical staff.
The salary bill of each category is multiplied with appropriate multiplier to ascertain the total value of each category for the organisation at a given point of time.
Here, multiplier is an instrument that relates the personal worth of employees with the total asset values of the organisation. As per principle, the value of human asset should match with the value of goodwill.
Inconsistency in the value of human assets in comparison to goodwill is indicative of inaccuracy in multiplier that should be adjusted accordingly.
5. Economic Value Method: Under this method, human asset is valued on the basis of the contribution they are likely to make to the organisation till their retirement from the jobs.
The payments made to them in the form of pay, allowances, benefits, etc. are estimated and then discounted appropriately to arrive at the present economic value of the individuals. This model can be expressed in the following formula:

Where, V, = the human capital value of an individual r years old.
E(t) = the individual's annual earnings upto retirement, represented by the earnings profile.
r = discount rate i.e., cost of capital.
T = retirement age.
The drawback of this method is that the under or over-fixation of salary may affect equating the total earnings to the human capital.
