(1) These investments are highly liquid investments in money market funds for both fiscal 2011 and 2010. 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 Consolidated Balance Sheets.

(2) The Company maintains a self-directed, non-qualified deferred compensation plan for certain executives and other highly compensated employees. At the end of fiscal 2011 the plan assets and liabilities are invested in actively traded mutual funds and individual stocks valued using observable quoted prices in active markets. At the end of fiscal 2010 the plan assets are invested in a money market fund and valued using observable quoted prices in active markets. The deferred compensation plan liabilities included in Level II are valued using quoted prices for similar assets or liabilities 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 Consolidated Balance Sheets.

(3) Derivative assets and liabilities included in Level II represent forward currency exchange contracts. The Company typically 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 Consolidated Balance Sheets.

(4) The Company has eight contingent consideration arrangements that require it to pay the former owners of certain companies it acquired during fiscal 2011, 2010 and 2009. The undiscounted maximum payment under all seven arrangements is $12.8 million at the end of fiscal 2011, based on future revenues or gross margins. 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 0.06% to 3.50% for fiscal 2011 and 0.00% to 0.61% for fiscal 2010, respectively. At the end of fiscal 2011 and 2010, of the total contingent consideration liability, $4.5 million and $1.7 million was included in Other current liabilities, respectively, and $0.5 million and $2.0 million was included in Other non-current liabilities, respectively, on the Company's Consolidated Balance Sheets. During fiscal 2011 and 2010, the fair value of contingent consideration arrangements for businesses acquired by the Company was $2.8 million and $3.9 million, respectively. The Company recognized $0.3 million and $2.3 million, respectively, as a gain in the Company's Consolidated Statements of Income for changes in fair value, and made payments of $1.2 million.
