(1) These investments are highly liquid investments such as money market funds. The fair values are determined using observable quoted prices in active markets. Money market funds are included in Cash and cash equivalents on the Company's Condensed Consolidated Balance Sheets.

(2) The Company maintains a self-directed, non-qualified deferred compensation plan for certain executives and other highly compensated employees. As of September 30, 2011 the plan assets and liabilities are invested in actively traded mutual funds and individual stocks valued using observable quoted prices in active markets. Deferred compensation plan assets and liabilities are included in Other non-current assets and Other non-current liabilities on the Company's Condensed Consolidated Balance Sheets.

(3) Derivative assets and liabilities included in Level II represent forward currency exchange contracts. The Company enters into these contracts to minimize the short-term impact of foreign currency fluctuations on certain trade and inter-company receivables and payables. The derivatives are not designated as hedging instruments. The fair values are determined using inputs based on observable quoted prices. Derivative assets and liabilities are included in Other current assets and Other current liabilities, respectively, on the Company's Condensed Consolidated Balance Sheets.

(4) The Company has seven contingent consideration arrangements that require it to pay the former owners of certain companies it acquired during fiscal 2009 through fiscal 2011. The undiscounted maximum payment under all seven arrangements is $12.9 million, based on future revenues or gross margins over a 3 year period. The Company estimated the fair value of these liabilities using the expected cash flow approach with inputs being probability-weighted revenue or gross margin projections, as the case may be, and discount rates ranging from 0.02% to 3.50%. Of the total contingent consideration liability, $3.0 million and $2.1 million was included in Other current liabilities and Other non-current liabilities, respectively, on the Company's Condensed Consolidated Balance Sheets.
