Financing Agreement

On April 1, 2015, we entered into a $500 million second amended revolving credit and term loan agreement ("Second Amended Financing Agreement") to amend the terms of our existing revolving credit and term loan agreement ("Amended Financing Agreement"), to add an incremental $200 million term loan B borrowing and to increase the line of credit by $25 million. The $400 million term loan B matures in November 2020 and the $100 million revolving credit facility matures in November 2018.

The Second Amended Financing Agreement includes the maintenance of a net leverage ratio if we borrow more than 20% on the revolving credit facility. The term loan B requires that if we borrow additional amounts or make a permitted acquisition that we cannot exceed a stated net leverage ratio on a pro forma basis at the date of the transaction.

The Second Amended Financing Agreement allows us to make restricted payments (dividends and share repurchases) up to $70 million plus additional amounts based on our financial results and condition. We can also make additional stock repurchases equal to the amount of proceeds that we receive from the exercise of stock options held by our employees. Additionally, we can make acquisitions as long as the pro forma net leverage ratio is less than 4.5 to 1.0 of assets.

The Second Amended Financing Agreement in certain circumstances requires that we must use a portion of excess cash flow, and the proceeds from the sale, to repay debt. As of June 30, 2016, we were not required to make additional principal payments based on excess cash flow. Any proceeds, up to a stipulated amount, that we receive from the upcoming FCC spectrum auction, should we choose to participate and our bid is accepted, will not be required to be used to pay down the term loan.

Under the terms of the Second Amended Financing Agreement, we granted the lenders mortgages on certain of our real property, pledges of our equity interests in our subsidiaries and security interests in substantially all other personal property including cash, accounts receivables, and equipment.

Interest is payable on the term loan B at rates based on LIBOR with a 0.75% floor, plus a fixed margin of 2.75%. Interest is payable on the revolving credit facility at rates based on LIBOR plus a margin based on our leverage ratio ranging from 2.25% to 2.75%. As of June 30, 2016 and December 31, 2015, the interest rate was 3.50% on the term loan B. The weighted-average interest rate on borrowings was 3.50% and 3.37% for the six months ended June 30, 2016 and 2015, respectively.

Scheduled principal payments on the term loan at June 30, 2016 are: $2.0 million for the remainder of 2016, $4.0 million in 2017, $4.0 million in 2018, $4.0 million in 2019, and $378.5 million in 2020.

Commitment fees of 0.30% to 0.50% per annum, based on our leverage ratio, of the total unused commitment are payable under the revolving credit facility.

As of June 30, 2016 and December 31, 2015, we had outstanding letters of credit totaling $0.8 million.

Unsecured Subordinated Notes Payable

The unsecured subordinated promissory notes bear interest at a rate of 7.25% per annum payable quarterly. The notes are payable in equal annual installments of $2.7 million on September 30 of 2016, 2017 and 2018, with no prepayment right.
