DERIVATIVE FINANCIAL INSTRUMENTS

Heartland uses derivative financial instruments as part of its interest rate risk management strategy. As part of the strategy, Heartland considers the use of interest rate swaps, caps, floors and collars and certain interest rate lock commitments and forward sales of securities related to mortgage banking activities. Heartland's current strategy includes the use of interest rate swaps, interest rate lock commitments and forward sales of mortgage securities. In addition, Heartland is facilitating back-to-back loan swaps to assist customers in managing interest rate risk. Heartland's objectives are to add stability to its net interest margin and to manage its exposure to movement in interest rates. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amounts to be exchanged between the counterparties. Heartland is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. Heartland minimizes this risk by entering into derivative contracts with large, stable financial institutions. Heartland has not experienced any losses from nonperformance by these counterparties. Heartland monitors counterparty risk in accordance with the provisions of ASC 815.

In addition, interest rate-related derivative instruments generally contain language outlining collateral pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain threshold limits which are determined by credit ratings of each counterparty. Heartland was required to pledge no cash as collateral at December 31, 2018, and $1.2 million at December 31, 2017. At December 31, 2018, $770,000 collateral was required to be pledged by Heartland's counterparties compared to no collateral at December 31, 2017.

Heartland's derivative and hedging instruments are recorded at fair value on the consolidated balance sheets. See Note 20, "Fair Value," for additional fair value information and disclosures.

Cash Flow Hedges

Heartland has variable rate funding which creates exposure to variability in interest payments due to changes in interest rates. To manage the interest rate risk related to the variability of interest payments, Heartland has entered into various interest rate swap agreements. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are received or made on Heartland's variable-rate liabilities. For the twelve months ended December 31, 2018, the change in net unrealized losses on cash flow hedges reflects changes in the fair value of the swaps and reclassification from accumulated other comprehensive income to interest expense totaling $179,000. For the next twelve months, Heartland estimates that cash receipts and reclassification from accumulated other comprehensive income to reduce interest expense will total $111,000.

Heartland entered into six forward-starting interest rate swap transactions to effectively convert Heartland Financial Statutory Trust IV, V, VI, and VII, which total $85.0 million, as well as Morrill Statutory Trust I and II, which total $20.0 million, from variable rate subordinated debentures to fixed rate debt. For accounting purposes, these six swap transactions are designated as cash flow hedges of the changes in LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on $105.0 million of Heartland's subordinated debentures that reset quarterly on a specified reset date. At inception, Heartland asserted that the underlying principal balance would remain outstanding throughout the hedge transaction making it probable that sufficient LIBOR-based interest payments would exist through the maturity date of the swaps.

Heartland entered into an interest rate swap transaction on May 10, 2016, to effectively convert $40.0 million of amortizing term debt from variable rate debt to fixed rate debt. For accounting purposes, this swap is designated as a cash flow hedge of the changes in LIBOR, the benchmark interest rate being hedged, associated with the interest payments on the amortizing term debt that resets monthly on a specified reset date. The swap expires on May 10, 2021.

During 2017, as noted in Note 11, "Other Borrowings," Heartland repurchased and retired $15.0 million of Heartland Statutory Trust IV which was part of a $25.0 million interest rate swap. The retired debt was replaced with the $15.0 million Citywide Statutory Trust V, which along with the remaining $10.0 million of Heartland Statutory Trust IV constitutes the underlying hedged items. The replacement of Citywide Trust V as the underlying hedged item had no impact to income.

On May 18, 2018, in connection with the acquisition of First Bank Lubbock Bancshares, Inc., Heartland acquired cash flow hedges related to OCGI Statutory Trust III and OCGI Capital Trust IV with notional amounts of $3.0 million and $6.0 million, respectively. The cash flow hedges effectively convert OCGI Statutory Trust III and OGCI Capital Trust IV from variable rate subordinated debentures to fixed rate debt. These swaps are designated as cash flow hedges of the changes in LIBOR, the benchmark interest rate being hedged, associated with the interest payments made on $9.0 million of Heartland's subordinated debentures that reset quarterly on a specified reset date.

Fair Value Hedges

Heartland uses interest rate swaps to convert certain long term fixed rate loans to floating rates to hedge interest rate risk exposure. Heartland uses hedge accounting in accordance with ASC 815, with the unrealized gains and losses, representing the change in fair value of the derivative and the change in fair value of the risk being hedged on the related loan, being recorded in the consolidated statements of income. The ineffective portions of the unrealized gains or losses, if any, are recorded in interest income and interest expense in the consolidated statements of income. Heartland uses statistical regression to assess hedge effectiveness, both at the inception of the hedge as well as on a continual basis. The regression analysis involves regressing the periodic change in the fair value of the hedging instrument against the periodic changes in the fair value of the asset being hedged due to changes in the hedge risk.

Heartland was required to pledge $2.5 million and $3.9 million of cash as collateral for these fair value hedges at December 31, 2018, and December 31, 2017, respectively.

Embedded Derivatives

Heartland has fixed rate loans with embedded derivatives. The loans contain terms that affect the cash flows or value of the loan similar to a derivative instrument, and therefore are considered to contain an embedded derivative. The embedded derivatives are bifurcated from the loans because the terms of the derivative instrument are not clearly and closely related to the loans. The embedded derivatives are recorded at fair value on the consolidated balance sheets as a part of other assets, and changes in the fair value are a component of noninterest income. The table below identifies the notional amount, fair value and balance sheet category of Heartland's embedded derivatives as of December 31, 2018, and December 31, 2017, in thousands:



	Notional Amount		Fair Value			Balance Sheet Category
December 31, 2018
Embedded derivatives	$	11,266	$	453		Other assets
Embedded derivatives	$	2,231	$	(54	)	Other liabilities
December 31, 2017
Embedded derivatives	$	14,045	$	738		Other assets

The table below identifies the gains and losses recognized on Heartland's embedded derivatives for the years ended December 31, 2018 and December 31, 2017, in thousands:



	Amount of Gain (Loss)		Income Statement Category

Embedded derivatives	$	339	Other noninterest income
December 31, 2017
Embedded derivatives	$	366	Other noninterest income

In conjunction with the CIC Bancshares, Inc., transaction on February 5, 2016, Heartland acquired convertible subordinated debt. The subordinated debt has a face value of $2.0 million, and the embedded conversion option allows the holder to convert the debt to Heartland common equity in any increment and at the discretion of the holder. The conversion option is bifurcated from the debt because the terms of the conversion option are not clearly and closely related to the terms of the debt. On February 5, 2016, the total number of shares to be issued upon conversion was 73,394.

As of December 31, 2016, the remaining shares to be issued upon conversion totaled 20,481. During 2017, all of the remaining convertible subordinated debt was converted to common stock, resulting in the issuance of 20,481 shares of common stock. At December 31, 2018, the remaining shares to be issued upon conversion totaled $0 and the notional amount of the embedded conversion option was $0.

For the years ended December 31, 2018, and December 31, 2017, $0 and $422,000, respectively, was recorded in other noninterest income for the embedded conversion option.

Back-to-Back Loan Swaps

Heartland has interest rate swap loan relationships with customers to meet their financing needs. Upon entering into these loan swaps, Heartland enters into offsetting positions with counterparties in order to minimize interest rate risk. These back-to-back loan swaps qualify as free standing financial derivatives with the fair values reported in other assets and other liabilities on the consolidated balance sheets. Heartland was required to post $2.0 million and $1.6 million as of December 31, 2018, and December 31, 2017, respectively, as collateral related to these back-to-back swaps. Heartland's counterparties were required to pledge $680,000 and $190,000 as of December 31, 2018 and December 31, 2017, respectively, related to these back-to-back swaps. Any gains and losses on these back-to-back swaps are recorded in noninterest income on the consolidated statements of income, and for the years ended December 31, 2018, and December 31, 2017, no gains or losses were recognized. The table below identifies the balance sheet category and fair values of Heartland's derivative instruments designated as loan swaps at December 31, 2018 and 2017, in thousands:



	Notional Amount		Fair Value			Balance Sheet Category	Weighted Average Receive Rate		Weighted Average Pay Rate
December 31, 2018
Customer interest rate swaps	$	211,246	$	4,449		Other Assets	5.10	%	4.96	%

Other Free Standing Derivatives

Heartland has entered into interest rate lock commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans and mortgage backed securities that are considered derivative instruments. Heartland enters into forward commitments for the future delivery of residential mortgage loans when interest rate lock commitments are entered into in order to economically hedge the effect of future changes in interest rates on the commitments to fund the loans as well as on residential mortgage loans available for sale. The fair value of these commitments is recorded on the consolidated balance sheets with the changes in fair value recorded in the consolidated statements of income as a component of gains on sale of loans held for sale. These derivative contracts are designated as free standing derivative contracts and are not designated against specific assets and liabilities on the consolidated balance sheets or forecasted transactions and therefore do not qualify for hedge accounting treatment. Heartland was required to pledge $35,000 and $20,000 at December 31, 2018, and December 31, 2017, respectively, as collateral for these forward commitments. Heartland's counterparties were required to pledge no cash as collateral at December 31, 2018, and $29,000 at December 31, 2017, as collateral for these forward commitments.

Heartland acquired undesignated interest rate swaps in 2015. These swaps were entered into primarily for the benefit of customers seeking to manage their interest rate risk and are not designated against specific assets or liabilities on the consolidated balance sheet or forecasted transactions and therefore do not qualify for hedge accounting in accordance with ASC 815. These swaps are carried at fair value on the consolidated balance sheets as a component of other liabilities, with changes in the fair value recorded as a component of other noninterest income.
