Cash, cash equivalents, and marketable securities as of December 31, 2017 were $329.4 million, an increase of $145.7 million from September 30, 2017, mainly due to the issuance of $172.5 million aggregate principal amount of the 2023 convertible notes during the quarter and cash generated from operating activities of approximately $59.8 million, offset by the $56.8 million paid to extinguish a portion of our existing 2018 convertible notes. Adjusted EBITDA for the quarter was $36.8 million.
2018 First Quarter Outlook
Effective January 1, 2018, the Company adopted Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers in Accounting Standards Codification Topic 606 (“ASC 606”), which supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition (“ASC 605”). The Company expects the adoption of ASC 606 to materially impact the timing of revenue recognition for its fixed-fee intellectual property licensing arrangements. The Company does not expect the adoption of ASC 606 to have a material impact on its other revenue streams, cashflow from operations, or the underlying financial position of the Company.
The Company has provided its first quarter outlook under both ASC 606 and ASC 605 in order to provide additional transparency. The Company believes that providing this additional disclosure in the short term will help our investors and analysts understand the impact of the change in revenue recognition standards, especially given the material difference expected in the timing of revenue recognition for our fixed-fee licensing arrangements as mentioned above. Note that the presentation under ASC 605 is not a substitute for the new ASC 606 revenue recognition standard under GAAP applicable for the first quarter of 2018.
Additionally, the guidance below under ASC 606 and ASC 605 excludes results from our lighting division. Given that the lighting division has been roughly breakeven for the Company, this exclusion does not impact the Company’s outlook on profitability, though it does reduce revenue outlook by roughly $4.0 million for the first quarter of 2018.
