The unaudited condensed consolidated financial statements donot include all of the disclosures required for complete annual financial statements prepared in conformity with U.S. GAAP.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The Partnership evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods the Partnership considers reasonable in each circumstance. Any effects on the Partnership’s business, financial position, or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Although the Partnership believes these estimates are reasonable, actual results could differ from those estimates.
