There is a schedule K-3 that needs completed.

Here's some brief info about the partnership:

..no active business income...it .receives various types of passive investment income, such as interest, dividends and return of capital, from subsidiary corporations that carry on business in various jurisdictions.

The amount of interest, dividends and returns of capital that is earned and then allocated to unitholders will vary depending upon the particular business unit(s) from which funds are sourced. The source of funds for the distributions will also affect how much if any of the distributions are subject to withholding tax.
