Restructuring

Q4 2013 Restructuring Plan

During the fourth quarter of 2013, Codexis' board of directors approved and committed to a restructuring plan (the “Q4 2013 Restructuring Plan”) to reduce its cost structure resulting from Codexis' decision to begin winding down its CodeXyme^® cellulase enzymes program, which included a total of 15 employee terminations in the United States. For the year ended December 31, 2013, costs of $809,000 for employee severance and other termination benefits have been recognized, consisting of $573,000 in research and development expenses and $236,000 in selling, general and administrative expenses. For the three months ended March 31, 2014, Codexis made severance payments of $238,000 and there was no remaining liability at March 31, 2014. Associated with the Q4 2013 Restructuring Plan, Codexis announced it was selling certain research and development assets that had become excess to future requirements (see Note 8, "Assets Held for Sale"). We do not anticipate recording any further costs under this restructuring plan.

All obligations under the restructuring plans were satisfied in the first quarter of 2014. The following table summarizes the activity in the restructuring accrual for the three months ended March 31, 2014 (in thousands):
