As of December 31, 2019 and 2018, we had forward foreign currency contracts in place which we had designated as hedges of our net investments in foreign operations.

From time to time, we may also utilize foreign currency forward contracts as part of our overall foreign currency risk management strategy or to obtain exposure to a particular financial market, as well as for yield enhancement in non-qualifying hedging relationships. We may also utilize equity call option instruments either to obtain exposure to a particular equity instrument or for yield enhancement in non-qualifying hedging relationships.

During the years ended December 31, 2019 and 2018, we recorded unrealized gains of approximately $0.5 million and unrealized losses of $9.4 million respectively, within net earnings, on the call options on equities which we purchased in 2018 at a cost of $10.0 million. These call options on equities had a fair value of less than $0.1 million and $0.6 million as of December 31, 2019 and 2018, respectively.

In 2019 we entered into a forward interest rate swap, with a notional amount of AUD$120.0 million, to partially mitigate the risk associated with declining interest rates until the receipt of the assets related to the Munich Re transaction, as discussed in Note 3 - "Significant New Business", which is expected to close in 2020. The carrying value of the forward interest rate swap, recorded in other liabilities, was $0.3 million as of December 31, 2019. We recorded unrealized losses in net earnings of $0.3 million on the instrument for the year ended December 31, 2019.
