[1] KLA-Tencor has a non-qualified deferred compensation plan under which 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. Participants can generally elect the distributions to be paid in lump sum or quarterly cash payments over a scheduled period for up to 15 years and are allowed to make subsequent changes to their existing elections as permissible under the plan provisions. The liability associated with deferred compensation plan is included as a component of other current liabilities. The Company also has a deferred compensation asset that corresponds to the liability under the deferred compensation plan and it is included as a component of other non-current assets. The plan assets are classified as trading securities.
