Restatement:

The Partnership has made the following correction relating to its use of the composite depreciation method.

This correction, which impacts the Balance Sheet at September 30, 2012 and the Statement of Operations and Other Comprehensive Income for the three-, nine-, and twelve-month periods ended September 30, 2012, reflects a subsequent determination that a disposition from the Partnership's composite group of assets was considered to be unusual. In certain situations under the composite method, disposals are considered unusual and, accordingly, losses are not included in the composite depreciation pool but are rather charged immediately to expense. In 2013, the Partnership's initial determination of whether a specific asset retired under the composite method of depreciation in 2011 was normal, was reviewed in connection with a response to an SEC comment letter. The Partnership ultimately concluded that such disposition was unusual and that an $8.8 million charge should be reflected in the 2011 financial statements.

The tables below reflect the impact on the financial statements of the correction as described above.
