Fair Value of Financial Instruments FAIR VALUE OF FINANCIAL INSTRUMENTS
We believe that the fair values of our current assets and current liabilities approximate their reported carrying amounts. We present the carrying values and the fair values of noncurrent financial assets and liabilities that qualify as financial instruments, determined under current guidance for disclosures on the fair value of financial instruments, in the following table:

The carrying value of our Credit Facility borrowings approximate fair value because they bear interest at a market rate. See Note 13. Fair Value of Financial Instruments and the “Fair Value Measurements” caption of Note 2. Summary of Significant Accounting Policies of our 2019 Form 10-K for more information on the input levels we use in determining fair value.
