Use of Estimates and Assumptions in Preparation of Consolidated Financial Statements	Use of Estimates and Assumptions in Preparation of Consolidated Financial Statements The preparation of financial statements in conformity with GAAP requires the Partnership to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The accompanying interim unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the SEC. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such SEC rules and regulations, although the Partnership believes that the disclosures are adequate to make the information presented not misleading.

The Partnership’s condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2023. These condensed consolidated financial statements and notes have been prepared consistently with the 2023 Form 10-K. In the opinion of management, all adjustments (consisting of normal and recurring accruals) necessary to present fairly the Partnership’s financial position as of June 30, 2024, and the results of operations for the interim periods presented, have been made. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year.

Risks And Uncertainties	Risks and Uncertainties The Federal Reserve has recently maintained rates at the current levels as it analyzes further employment, price and economic data for indications of inflation declining to its long-term annual inflation target of 2%. The Federal Reserve continues to reduce its balance sheet of US treasury bonds and mortgage-backed securities which may cause further upward pressure on interest rates. In addition, geopolitical conflicts continue to impact the general global economic environment. These factors have maintained volatility in the fixed income markets, which has impacted the value of some of the Partnership’s investment assets, particularly those with fixed interest rates, which may result in collateral posting requirements under our debt financing arrangements. In addition, increases in short-term interest rates will generally result in increases in the interest cost associated with the Partnership’s variable rate debt financing arrangements and for construction debt of properties underlying our investments in unconsolidated entities. The extent to which general economic, geopolitical, and financial conditions will impact the Partnership’s financial condition or results of operations in the future is uncertain and actual results and outcomes could differ from current estimates. The recent inflationary environment in the United States may increase operating expenses at properties securing the Partnership’s investments and general operations, which may reduce net operating results of the related properties and result in lower debt service coverage or higher than anticipated capitalized interest requirements for properties under construction. Such occurrences may negatively impact the value of the Partnership’s investments. Increasing general and administrative expenses of the Partnership may adversely affect the Partnership’s operating results, including a reduction in net income. Furthermore, the potential for an economic recession either globally or locally in the U.S. or other economies could further impact the valuation of our investment assets, limit the Partnership’s ability to obtain additional debt financing from lenders, and limit opportunities for additional investments.
BUCs	BUCs The Partnership has issued BUCs representing assigned limited partnership interests to investors. Costs related to the issuance of BUCs are recorded as a reduction to partners’ capital when issued. The Partnership declared BUCs Distributions in the form of additional BUCs during the six months ended June 30, 2024 and the year ended December 31, 2023. All fractional BUCs resulting from the BUCs Distributions received cash for such fraction based on the market value of the BUCs on the record date. The BUCs Distributions have been applied retroactively to all net income per BUC, distributions per BUC and similar per BUC disclosures for all periods indicated in the Partnership’s condensed consolidated financial statements.
Reclassification	Reclassification Certain prior year amounts have been reclassified for consistency with the current period presentation. For the year ended December 31, 2023, the Partnership began reporting the realized and unrealized (gains) losses of its derivative transactions within “Net result from derivative transactions” on the Partnership’s consolidated statements of operations. Previously, the realized and unrealized (gains) losses of the Partnership's derivative transactions had been reported within "Interest expense" on the Partnership’s consolidated statement of operations. Accordingly, for the three and six months ended June 30, 2023, the Partnership has included the realized and unrealized (gains) losses of its derivative transactions within “Net result from derivative transactions” in conformity with the current reporting period presented herein. This reclassification has no effect on the Partnership’s reported “Net income” or “Partners’ capital” in the Partnership’s condensed consolidated financial statements for the periods presented.
