§ 121-504. Sharing of distributions. Distributions of cash or other assets of a limited partnership shall be allocated among the partners, and among classes of partners, in the manner provided in the partnership agreement which may, among other things, establish record dates for distributions. If the partnership agreement does not so provide, distributions shall be allocated on the basis of the value, as stated in the records of the limited partnership, if so stated, of the contributions, but not including defaulted obligations to make contributions, of each partner to the extent they have been received by or promised to the limited partnership and have not been returned.
