What is Capital Structure?

The capital structure represents the relationship among different kinds of long-term capital. Normally, a firm raises long-term capital through the issue of common shares, sometimes accompanied by preference shares.


According to Gerestenberg “capital structure of a company refers to the composition or makeup of its capitalization and it includes all long term capital resources viz., loans, reserves, shares, and bonds”.

according to James C. Van Horne “The mix of a firm’s permanent long-term financing represented by debt, preferred stock, and common stock equity”.
It is the permanent financing of a firm represented by long-term debt, preferred stock, and net worth. So it relates to the arrangement of capital and excludes short-term borrowings. It denotes some degree of permanency as it excludes short-term sources of financing.
