Defined Benefit Pension Plan | Defined Benefit Pension Plan Nanometrics sponsors a statutory government mandated defined benefit pension plan (the “Benefit Plan”) in Taiwan for its local employees. The fair value of plan assets was $0.2 million, $0.2 million and $0.1 million for the fiscal years ended 2013, 2012 and 2011, respectively; and the net funding deficiency of the Benefit Plan was $0.2 million, $0.3 million, and $0.2 million for the fiscal years ended December 28, 2013, December 29, 2012, and December 31, 2011, respectively. Based on the nature and limited extent of the pension plan, we determined this pension plan was not material for separate disclosure.
