Amendment Description	Solar Power, Inc. (the ?Company?) is filing this Amendment No. 1 to its Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 16, 2013. This filing amends and restates our previously reported financial statements for the six months ended June 30, 2013 to reflect revised presentation of cash flows in connection with the issuance of notes receivables as discussed below and in Note 19 to the Condensed Consolidated Financial Statements. Based on its review, management determined that the Company improperly reported cash flows between operating and investing activities which resulted in a $17 million overstatement of cash flows from operating activities and a $17 million understatement of cash flows from investing activities due to the improper classification of a portion of the conversion of $30.6 million of accounts receivables into notes receivables during the second quarter of 2013. The transactions should have been disclosed as operating activities in accordance with accounting standards. During the second quarter of 2013, the Company converted certain accounts receivables into notes receivables. The receivables were generated from the performance of engineering, procurement and construction services related to the Company?s primary operations. Accordingly, the issuance and repayment on notes receivables related to operations should have been reported as changes in operating cash flows. However, the Company incorrectly reported the issuance of notes receivable and proceeds from repayment on notes receivable as investing activities within the statement of cash flows for the six months ended June 30, 2013. In addition, the Company incorrectly disclosed a non-cash investing activity for the reclassification of accounts receivable to notes receivable. The results of this change on the Consolidated Statements of Cash Flows for the six months ended June 30, 2013 are discussed under Note 19 to the Condensed Consolidated Financial Statements. This filing also amends previously issued Note 12 to the Condensed Consolidated Financial Statements as discussed below: ? To add disclosure regarding the assets pledged as security for the two China Development Bank ?CDB? loan facilities. ? To clarify the second Facility Agreement is for a $15.6 million facility and a RMB 77,850,000 ($12.3 million at current exchange rates) facility and relates to EPC financing for another project with customer KDC; and to clarify the Company never borrowed funds under the RMB 72,150,000 facility with CDB. This filing also amends previously issued Note 14 to the Condensed Consolidated Financial Statements to present the required quantitative fair value disclosures using a tabular format. This Amendment No. 1 amends and restates the following item of our Form 10-Q/A as affected by the revised presentation of cash flows for the issuance of notes receivables: (i) Part I, Item 1 ? Financial Statements; (ii) Part I, Item 2 ? Management?s Discussion and Analysis of Financial Condition and Results of Operations; and (iii) Part II, Item 6 ? Exhibits. All information in our Quarterly Report on Form 10-Q/A for the six months ended June 30, 2013, as amended by this Amendment No. 1, speaks as of the date of the original filing of our Form 10-Q for such period and does not reflect any subsequent information or events, except as expressly noted in this Amendment No. 1 and except for Exhibits 31.1, 31.2, and 32. All information contained in this Amendment No. 1 is subject to updating and supplementing as provided in our reports, as amended, filed with the Securities and Exchange Commission subsequent to the date of the initial filing of our Quarterly Report on Form 10-Q for the six months ended June 30, 2013.
