Credit Risk and Fair Value of Financial Instruments

Fair Value Estimates

The fair value estimates of the following financial instruments have been determined using available market information and appropriate valuation methodologies. The carrying values of cash and cash equivalents, trade receivables, and trade payables approximate the fair values of those instruments due to the short-term nature of the instruments. The carrying values of receivables on preneed funeral and cemetery contracts approximate fair value due to the diverse number of individual contracts with varying terms.

The fair value of our debt instruments was as follows:

The fair values of our long-term, fixed rate loans were estimated using market prices for those loans, and therefore they are classified within Level 2 of the fair value measurements hierarchy. The Term Loan, Bank Credit Facility agreement, and the mortgage and other debt are classified within Level 3 of the fair value measurements hierarchy. The fair values of these instruments have been estimated using discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements. An increase (decrease) in the inputs results in a directionally opposite change in the fair value of the instruments.

Credit Risk Exposure

Our cash deposits, some of which exceed insured limits, are distributed among various market and national banks in the jurisdictions in which we operate. In addition, we regularly invest excess cash in financial instruments that are not insured, such as commercial paper that is offered by corporations with quality credit ratings and money market funds and Eurodollar time deposits that are offered by a variety of reputable financial institutions. We believe that the credit risk associated with such instruments is minimal.

We grant credit to customers in the normal course of business. The credit risk associated with our funeral, cemetery, and preneed funeral and preneed cemetery receivables due from customers is generally considered minimal because of the diversification of the customers served. Furthermore, bad debts have not been significant relative to the volume of deferred revenue. Customer payments on preneed funeral or preneed cemetery contracts that are either placed into state-regulated trusts or used to pay premiums on life insurance contracts generally do not subject us to collection risk. Insurance-funded contracts are subject to supervision by state insurance departments and are protected in the majority of states by insurance guaranty acts.
