We are exposed to market risks related to fluctuations in interest rates. To mitigate these risks, we utilize derivative instruments in the form of interest rate swaps. We do not enter into derivative transactions for speculative purposes.

In 2014, we entered into two interest rate swap agreements for a total notional amount of $50 million to hedge changes in the variable rate interest expense on $50 million of our existing or replacement LIBOR-priced debt. The first swap agreement of $25 million expired on August 29, 2019, and under the second swap agreement, we have fixed the LIBOR portion of the interest rate at 2.5% through August 29, 2024. This swap is measured at fair value and recorded in our Consolidated Balance Sheet as an asset or liability. It is designated and qualifies as a cash flow hedging instrument and is highly effective. Unrealized losses are deferred to shareholders' equity as a component of accumulated other comprehensive gain (loss) and are recognized in income as an increase or decrease to interest expense in the period in which the related cash flows being hedged are recognized in expense.

Our Credit Facility bears interest at variable rates from LIBOR plus 1.375% to a maximum of LIBOR plus 2.00%. As a result of the interest rate swap agreement, we are subject to interest rate risk on debt in excess of $25 million drawn on our Credit Facility.

At September 30, 2019, we had fixed rate long-term debt aggregating $175 million and variable rate long-term debt aggregating $124 million, after taking into account the effect of the swap.

The fair values of outstanding derivative instruments are as follows (in thousands):

The fair value of all outstanding derivatives was determined using a model with inputs that are observable in the market (Level 2) or can be derived from or corroborated by observable data.
