Because those laws are not uniform, the characteristics of LPCs vary from state to state. However, LLPs generally have the following characteristics: An LLP is an unincorporated association of two or more "persons"; Its members have limited personal liability for the obligations or debts of the entity; It is classified as a partnership for federal income tax purposes.

The accounting described would apply irrespective of whether the redeemable preferred stock may be voluntarily redeemed by the issuer prior to the mandatory redemption date, or whether it may be converted into another class of securities by the holder.
