Alternately, a capital note is a bond with a very long maturity horizon, reaching several decades (sometimes as much as 50 or 100 years). Unlike equity securities, these capital notes do mature at some point; therefore, they form part of the company's liabilities and not part of equity. However, since their maturity is so far in the future, they are treated as equity for practical purposes; the company keeps the money raised through them inside its balance sheet for a very long time. Banks and other financial institutions issue these bonds to satisfy regulatory demands regarding capital requirements, specifically under the Basel Accords. In the Basel "tiers" system, capital notes are treated as close to equity, as both reinforce the bank's "capital". Additionally, bank capital notes are usually not collateralized and are contractually subordinated, forming a junior class of debt. Similar terms might be found in redeemable preferred shares.
Contrary to the warrant-like capital notes described above, these capital notes are usually not convertible, so they represent no current or future stake in the corporation's equity (share capital).
