Description of the type or class of security that is classified as temporary equity, including its redemption features (for example, sinking fund, at option of holders, out of future earnings), conversion features, and the rights of holders, if any, in the event of default, including the effect, if any, on junior securities in the event a required dividend, sinking fund, or other redemption payment(s) is not paid. Include also a description of stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer. Temporary equity is a security with redemption features that are outside the control of the issuer, is not classified as an asset or liability in conformity with GAAP, and is not mandatorily redeemable. Includes any type of security that is redeemable at a fixed or determinable price or on a fixed or determinable date or dates, is redeemable at the option of the holder, or has conditions for redemption which are not solely within the control of the issuer. If convertible, the issuer does not control the actions or events necessary to issue the maximum number of shares that could be required to be delivered under the conversion option if the holder exercises the option to convert the stock to another class of equity. If the security is a warrant or a rights issue, the warrant or rights issue is considered to be temporary equity if the issuer cannot demonstrate that it would be able to deliver upon the exercise of the option by the holder in all cases. Includes stock with put option held by ESOP and stock redeemable by holder only in the event of a change in control of the issuer.
