Settlement Agreement With Samsung |
Settlement Agreement with Samsung | 3. Settlement Agreement with Samsung On January 19, 2010, the Company, Samsung and certain related entities of Samsung entered into a Settlement Agreement (the “Settlement Agreement”) to release all claims against each other with respect to all outstanding litigation between them and certain other potential claims. Pursuant to the Settlement Agreement, the Company and Samsung entered into a Semiconductor Patent License Agreement on January 19, 2010 (the “License Agreement”), under which Samsung licenses from the Company non-exclusive rights to certain Rambus patents and has agreed to pay the Company cash amounts equal to approximately $25.0 million per quarter, subject to certain adjustments and conditions related to their DRAM revenue. These payments commenced in the first quarter of 2010 and will conclude in the last quarter of 2014. The settlement with Samsung is a multiple element arrangement for accounting purposes. For a multiple element arrangement, the Company is required to determine the fair value of the elements. The Company considered several factors in determining the accounting fair value of the elements of the settlement with Samsung which included a third party valuation using an income approach, the Black-Scholes-Merton option pricing model and a residual approach (collectively the “Fair Value”). The total gain related to the settlement with Samsung of $133.0 million was recognized through the end of the first quarter of 2011, of which $6.2 million was recognized in the first quarter of 2011. The gain from settlement represents the Fair Value of the cash consideration allocated to the settlement of the antitrust litigation and the residual value of other elements.
