Schedule of Derivative Instruments

Derivatives designated as cash flow hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the aggregate fair value of the derivative instrument is recorded in other assets or other liabilities with any gain or loss related to changes in fair value recorded in accumulated other comprehensive income, net of tax. The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. Pinnacle Financial uses interest rate floors in an effort to mitigate the impact of declining interest rates on LIBOR-based variable rate loans. Pinnacle Financial uses forward cash flow hedges in an effort to manage future interest rate exposure on borrowings. The hedging strategy converts the LIBOR-based variable interest rate on forecasted borrowings to a fixed interest rate and is used in an effort to protect Pinnacle Financial from floating interest rate variability. A summary of Pinnacle Financial's cash flow hedge relationships as of March 31, 2020 and December 31, 2019 is as follows (in thousands):

					March 31, 2020				December 31, 2019

The effects of Pinnacle Financial's cash flow hedge relationships on the statement of comprehensive income (loss) during the three months ended March 31, 2020 and 2019 were as follows, net of tax (in thousands):

	Amount of Gain (Loss) Recognized in Other Comprehensive Income (Loss)
	Three Months Ended March 31,
Asset derivatives	2020		2019
Interest rate floor - loans	$	65,349	$	—
Liability derivatives
Interest rate swaps - borrowings	$	(1,580)	$	(523)
	$	63,769	$	(523)

The cash flow hedges were determined to be highly effective during the periods presented and as a result qualify for hedge accounting treatment. The hedge would no longer be considered effective if a portion of the hedge becomes ineffective, the item hedged is no longer in existence or Pinnacle Financial discontinues hedge accounting. Pinnacle Financial expects the hedges at March 31, 2020 to continue to be highly effective and qualify for hedge accounting during the remaining terms of the original hedging transactions. Losses totaling $1.8 million net of tax and gains totaling $256,000 net of tax were reclassified from accumulated other comprehensive income into net income during the three months ended March 31, 2020 and 2019, respectively. During the first quarter of 2020, loan interest rate floors entered into in the second quarter of 2019 with a notional amount totaling $1.3 billion and unrealized gains totaling $16.5 million were terminated. These unrealized gains will be amortized into income on a straight line basis through October 2021. Approximately $8.1 million in unrealized gains, net of tax, are expected to be reclassified from accumulated other comprehensive income (loss) into net income over the next twelve months related to cash flow hedges terminated prior to March 31, 2020.

Derivatives designated as fair value hedges

For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. Pinnacle Financial utilizes interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable available-for-sale securities. The hedging strategy converts the fixed interest rates to LIBOR-based variable interest rates. These derivatives are designated as partial term hedges of selected cash flows covering specified periods of time prior to the call dates of the hedged securities.
