&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 27pt; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including the accounts of the Company&amp;#8217;s newly established German subsidiary, Metabolix GmbH.&amp;#160;&amp;#160; All significant intercompany transactions were eliminated. Telles, LLC (&amp;#8220;Telles&amp;#8221;), the Company&amp;#8217;s former joint venture with Archer Daniels Midland Company (&amp;#8220;ADM&amp;#8221;) that terminated in early 2012, was not consolidated by the Company.&lt;/font&gt;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 26pt; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.&lt;/font&gt;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 26pt; MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;

&lt;p style="MARGIN: 0in 0in 0pt;"&gt;&amp;#160;&lt;/p&gt;
&lt;p style="TEXT-INDENT: 27pt; MARGIN: 0in 0in 0pt;"&gt;&lt;font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2"&gt;Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and short-term investments. The Company primarily invests its excess cash and cash equivalents in money market funds, corporate debt, federal agency notes and U.S. treasury notes. Investments are acquired in accordance with the Company&amp;#8217;s investment policy which establishes a concentration limit per issuer.&lt;/font&gt;&lt;/p&gt;

The Company performs ongoing credit evaluations of its customers&amp;#8217; financial condition and limits the amount of credit extended when deemed necessary. At June&amp;#160;30, 2013, the Company&amp;#8217;s accounts and unbilled receivables include $724 or 63% from U.S. and Canadian government grants and $315 or 27% from customer product sales. At December&amp;#160;31, 2012, the Company&amp;#8217;s accounts and unbilled receivables included $561 or 46% from U.S. and Canadian government grants and $535 or 44% from customer product sales. At June&amp;#160;30, 2013, no customer had accounts receivable due from product sales of 10% or greater, and December&amp;#160;31, 2012, one customer represented 41%, of accounts receivable due from product sales.&lt;/font&gt;&lt;/p&gt;
