Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On February 10, 2015, Landec Corporation (“Landec”) concluded that a material impairment charge was required in connection with its equity ownership in Aesthetic Sciences Corporation (“ASC”). In December 2005, Landec granted ASC an excusive license to use Landec’s Intelimer® materials technology for the development of dermal fillers, in exchange for which Landec received shares of preferred stock of ASC. The preferred stock is senior to ASC’s common stock but junior to any outstanding liabilities of ASC.

In July 2010, ASC sold the rights to its Smartfil™ system, including the related rights to the Intelimer technology, to a third party (“Acquirer”) in return for royalty payments on product sales over a five-year period that commenced on November 1, 2014. These royalty rights currently represent ASC’s only significant asset or projected future cash flow. On February 10, 2015, Landec obtained from the Acquirer, which became available for the first time because such information was not required to be disclosed until the royalty period commenced, data regarding historical sales of the Smartfil product. Based on this data, Landec has concluded that the likelihood is remote that ASC will earn royalties in amounts that exceed its liabilities, and thus, Landec does not expect to receive any return on its investment in ASC. As a result, Landec will record during its fiscal 2015 third quarter a non-cash impairment charge in the amount of $793,000, or $0.03 per share. Due to federal income tax limitations on the utilization of capital losses, no tax benefit associated with this impairment is expected to be recognized in the foreseeable future.

Forward-Looking Statements

The matters discussed above include forward-looking statements that involve certain risks and uncertainties that could cause actual results to differ materially, including such factors as the volume and timing of sales of the Smartfil products and the possibility that ASC could generate significant revenue from other sources or renegotiate its outstanding indebtedness. Landec undertakes no obligation to update or revise any forward-looking statements whether as a result of new developments or otherwise.
