Evidence That Greater Disclosure Lowers The Cost Of Equity Capital

The effect of corporate disclosure on the cost of equity capital is a matter of considerable interest and importance to both corporations and the investment community. However, the relationship between disclosure level and cost of capital is not well established and has proved difficult for researchers to quantify. As described in this article, the author's 1997 study (published in The Accounting Review) was the first to measure and detect a direct relationship between disclosure and cost of capital. After examining the annual reports of 122 manufacturing companies, the author concluded that companies providing more extensive disclosure had a lower (forward‐looking) cost of equity capital (measured using Value Line forecasts with an EBO valuation formula that derives from the dividend discount model). For companies with extensive analyst coverage, differences in disclosure do not appear to affect cost of capital. But for companies with small analyst followings, differences in disclosure do appear to matter. Among this group of companies, the firms judged to have the highest level of disclosure had a cost of equity capital that was nine‐percentage points lower than otherwise similar firms with a minimal level of disclosure. Closer analysis of some of the specific disclosure practices also suggests that, for small firms with limited analyst coverage, there are benefits to providing more forward‐looking information, such as forecasts of sales, profits, and capital expenditures, and enhanced disclosure of key non‐financial statistics, such as order backlogs, market share, and growth in units sold. In closing, the article also discusses an interesting new study (by Lang and Lundholm) that suggests there is an important distinction between effective corporate disclosure and “hyping the stock.” The findings of this study show that while higher levels of disclosures are associated with higher stock prices, sudden increases in the frequency of disclosure are viewed with skepticism.
