[1] | Cash and cash equivalents are comprised of cash on hand and time deposits and, due to their short maturities, the carrying values approximate their fair values.
[2] | At May 31, 2011 and November 30, 2010, substantially all of our long-term other assets were comprised of notes and other receivables. The fair values of notes and other receivables were based on estimated future cash flows discounted at appropriate market interest rates.
[3] | The net difference between the fair value of our fixed rate debt and its carrying value was due to the market interest rates in existence at May 31, 2011 and November 30, 2010 being lower than the fixed interest rates on these debt obligations, including the impact of changes in our credit ratings, if any. The net difference between the fair value of our floating rate debt and its carrying value was due to the market interest rates in existence at May 31, 2011 and November 30, 2010 being higher than the floating interest rates on these debt obligations, including the impact of changes in our credit ratings, if any. The fair values of our publicly-traded notes were based on their quoted market prices in active markets. The fair values of our other debt were estimated based on appropriate market interest rates being applied to this debt.

- Definition Includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the Entity may deposit additional funds at any time and also effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Compensating balance arrangements that do not legally restrict the withdrawal or usage of cash amounts may be reported as Cash and Cash Equivalents, while legally restricted deposits held as compensating balances against borrowing arrangements, contracts entered into with others, or company statements of intention with regard to particular deposits are not generally reported as cash and cash equivalents. Includes cash and cash equivalents associated with the entity's continuing operations. Excludes cash and cash equivalents associated with the disposal group (and discontinued operation). + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 210 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SX 210.5-02.1) -URI http://asc.fasb.org/extlink&oid=6877327&loc=d3e13212-122682 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 02 -Paragraph 1 -Article 5 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 95 -Paragraph 7 -Footnote 1 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
