(1) Cash and cash equivalents are stated at nominal value, which equals fair value. (2) Represents restricted deposits that are used to collateralize our insurance obligations and are stated at nominal value, which equals fair value. These insurance deposits are included in “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets. See Note 7, “Insurance,” for further information. (3) Represents investments held in a Rabbi trust associated with one of our deferred compensation plans, which we include in “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets. The fair value of the assets held in the funded deferred compensation plan is based on quoted market prices. (4) Represents gross outstanding borrowings under our syndicated line of credit and term loan. Due to variable interest rates, the carrying value of outstanding borrowings under our line of credit and term loan approximates the fair value. See Note 8, “Credit Facility,” for further information. (5) Represents interest rate swap derivatives designated as cash flow hedges. The fair values of the interest rate swaps are estimated based on the present value of the difference between expected cash flows calculated at the contracted interest rates and the expected cash flows at current market interest rates using observable benchmarks for LIBOR forward rates at the end of the period. At April 30, 2019 and October 31, 2018, our interest rate swaps are included in “Other noncurrent liabilities” and “Other noncurrent assets,” respectively, on the accompanying unaudited consolidated balance sheets. See Note 8, “Credit Facility,” for further information. (6) The fair value of investments in auction rate securities is based on discounted cash flow valuation models, primarily utilizing unobservable inputs, including assumptions about the underlying collateral, credit risks associated with the issuer, credit enhancements associated with financial insurance guarantees, and the possibility of the security being re-financed by the issuer or having a successful auction. At April 30, 2019 and October 31, 2018, we held an investment in one auction rate security that had an original principal amount, amortized cost, and fair value of $5.0 million that is included in “Other investments” on the accompanying unaudited consolidated balance sheets. This auction rate security is a debt instrument with a stated maturity in 2050. The interest rate for this security is designed to be reset through Dutch auctions approximately every thirty days; however, auctions for this security have not occurred since August 2007. At April 30, 2019 and October 31, 2018, there were no unrealized gains or losses on our auction rate security included in AOCI.
