a)Voluntary disclosure refers to disclosing on the part of
company's financial, non-financial and other relevant information
in it's annual report for the need of it's users (investors ,
potential investors, shareholders and others).
Options available to companies for voluntary disclosures include
mass communication sources like magazines , newspapers , annual
reports , letter to shareholders , press reports , management
forecasts , employee reports , interim reports , analyst's
presentation . But annual reports are the major formal source of
information among all the options available because it provides
deep information disclosure and are produced regularly.
b)Although there are several theories to explain voluntary
disclosure practices,three of them are as follows:
- Signalling Theory-It was
initially developed to resolve the information asymmetry in the
labour market but now it is used in corporates as well. In
it,companies disclose information to investors in order to prove
themselves better than other companies in the market and gain
goodwill.Here signalling implies depicting more information to
signal that jthey are better players.
- Capital need
theory- It's main aim is to raise finance from
external sources(debt or equity) at a low cost.Return for
investors's uncertainty is a cost of capital for the
company.Therefore reduction in cost of capital is acheived when
investors are able to interpret companiy's economies of scale
through voluntary disclosure.It was thought to be a positive
relation between cost of capital and voluntary disclosure but
Boston research has shown that it might have opposite effect
also.
- Legitimacy theory- According
to this, a company's values must match with the society where it
operates in order to exist in the market.It has developed in
accounting as a means to answer "what, why, how and when" certain
situations are handled by the company.The annual report legitimates
the information to outside public about the company's social
acheivements.It is done both through mandatory and voluntary
disclosures.
