NOTE 14 – COMMITMENTS AND OFF-BALANCE-SHEET RISK

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit and standby letters of credit. Loan commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Standby letters of credit are conditional commitments issued by our Bank to guarantee the performance of a customer to a third party. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized, if any, in the balance sheet. Our maximum exposure to loan loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. We use the same credit policies in making commitments and conditional obligations as we do for on-balance sheet instruments. Collateral, such as accounts receivable, securities, inventory, and property and equipment, is generally obtained based on management’s credit assessment of the borrower. If required, estimated loss exposure resulting from these instruments is expensed and recorded as a liability. There was no liability balance for these instruments as of December 31, 2014 and 2013.

At year-end 2014 and 2013, the rates on existing off-balance sheet instruments were substantially equivalent to current market rates, considering the underlying credit standing of the counterparties.

Our maximum exposure to credit losses for loan commitments and standby letters of credit outstanding at year-end was as follows:

	2014		2013
Commercial unused lines of credit	$	554,856,000	$	257,937,000
Unused lines of credit secured by 1 – 4 family residential properties		60,983,000		23,429,000
Credit card unused lines of credit		11,649,000		9,013,000
Other consumer unused lines of credit		8,673,000		5,695,000
Commitments to make loans		110,126,000		58,799,000
Standby letters of credit		35,461,000		19,670,000
Total commitments	$	781,748,000	$	374,543,000

Commitments to make loans generally reflect our binding obligations to existing and prospective customers to extend credit, including line of credit facilities secured by accounts receivable and inventory, and term debt secured by either real estate or equipment. In most instances, line of credit facilities are for a one-year term and are at a floating rate tied to the Mercantile Bank Prime Rate, the Wall Street Journal Prime Rate or the 30-Day Libor rate. For term debt secured by real estate, customers are generally offered a floating rate tied to the Mercantile Bank Prime Rate or Wall Street Journal Prime Rate, and a fixed rate currently ranging from 4.00% to 7.00%. These credit facilities generally balloon within five years, with payments based on amortizations ranging from 10 to 20 years. For term debt secured by non-real estate collateral, customers are generally offered a floating rate tied to the Mercantile Bank Prime Rate or Wall Street Journal Prime Rate, and a fixed rate currently ranging from 4.00% to 7.50%. These credit facilities generally mature and fully amortize within five years.

Certain of our commercial loan customers have entered into interest rate swap agreements directly with our correspondent banks. To assist our commercial loan customers in these transactions, and to encourage our correspondent banks to enter into the interest rate swap transactions with minimal credit underwriting analyses on their part, we have entered into risk participation agreements with the correspondent banks whereby we agree to make payments to the correspondent banks owed by our commercial loan customers under the interest rate swap agreement in the event that our commercial loan customers do not make the payments. We are not a party to the interest rate swap agreements under these arrangements. As of December 31, 2014, the total notional amount of the underlying interest rate swap agreements was $15.4 million, with a net fair value from our commercial loan customers’ perspective of negative $2.9 million. These risk participation agreements are considered financial guarantees in accordance with applicable accounting guidance and are therefore recorded as liabilities at fair value, generally equal to the fees collected at the time of their execution. These liabilities are accreted into income during the terms of the interest rate swap agreements, generally ranging from an original term of four to fifteen years, and totaled less than $0.1 million at December 31, 2014 and December 31, 2013.

The following instruments are considered financial guarantees under current accounting guidance. These instruments are carried at fair value.

	2014				2013
	Contract		Carrying		Contract		Carrying
	Amount		Value		Amount		Value
Standby letters of credit	$	35,461,000	$	150,000	$	19,670,000	$	148,000

We were required to have $8.4 million and $1.5 million of cash on hand or on deposit with the Federal Reserve Bank of Chicago to meet regulatory reserve and clearing requirements at year-end 2014 and 2013, respectively.
