[1] KLA-Tencor has a non-qualified deferred compensation plan whereby certain executives and non-employee directors may defer a portion of their compensation. Participants are credited with returns based on their allocation of their account balances among measurement funds. The Company controls the investment of these funds, and the participants remain general creditors of KLA-Tencor. Distributions from the plan commence following a participant’s retirement or termination of employment or on a specified date allowed per the plan provisions, except in cases where such distributions are required to be delayed in order to avoid a prohibited distribution under Internal Revenue Code Section 409A. As of December 31, 2014 and June 30, 2014, the Company had a deferred compensation plan related asset and liability included as a component of other non-current assets and other current liabilities on the Condensed Consolidated Balance Sheets. The plan assets are classified as trading securities.
