DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES Interest Rate Derivative We are exposed to risks arising from rising interest rates on our variable rate debt instruments. To manage these risks, we periodically use interest rate derivatives, which currently consists of an interest rate cap. To mitigate nonperformance risk, we routinely use a third party’s analysis of the creditworthiness of the counterparties, which supports our belief that the counterparties’ nonperformance risk is limited. All derivatives are recorded at fair value. During 2018, we entered into an interest rate cap with a notional amount of $36.0 million and a rate cap of 2.2%. The interest rate cap had an effective date of March 21, 2018 and terminates on March 1, 2021. This instrument was not designated as a cash flow hedge.
