On April 28, 2015, we entered into an amended and restated $450.0 million senior credit agreement (the "amended and restated senior credit agreement"). The amended and restated senior credit agreement consists of a $450.0 million revolving credit facility expiring on April 28, 2020. There were $265.6 million in borrowings outstanding on the revolving credit facility as of December 31, 2015. Our available borrowings on the revolving credit facility at December 31, 2015 were $179.3 million with approximately $5.1 million of outstanding letters of credit.

Interest rates on the amended and restated senior credit agreement are at LIBOR plus 1.50% (1.93% at December 31, 2015) or an alternative base rate. For those borrowings where we elect to use the alternative base rate, the base rate will be the greater of the Prime Rate, the Federal Funds Rate in effect on such date plus 0.50%, or the one month Eurocurrency rate plus 1.00%, plus an additional margin of 0.50%.

The amended and restated senior credit agreement is collateralized by substantially all of our personal property and assets. The amended and restated senior credit agreement contains covenants and restrictions which, among other things, require the maintenance of certain financial ratios (the most restrictive of which is the senior leverage ratio) and restrict dividend payments and the incurrence of certain indebtedness and other activities, including acquisitions and dispositions. We were in full compliance with these covenants and restrictions as of December 31, 2015. We are also required, under certain circumstances, to make mandatory prepayments from net cash proceeds from any issuance of equity and asset sales.

On January 17, 2013, we had entered into an amended and restated credit agreement. In connection with the refinancing, we recorded a $0.3 million loss on the early extinguishment of debt related to the write-off of unamortized deferred financing costs under the then existing senior credit agreement.

As further described in Note 15, on January 4, 2016, we entered into a fifth amended and restated senior credit agreement (the “fifth amended and restated senior credit agreement”) consisting of: (a) a $175.0 million term loan facility and (b) a $525.0 million revolving credit facility both expiring on January 4, 2021. The term loan is payable in quarterly installments increasing over the term of the facility.

We have a mortgage note outstanding in connection with the Largo, Florida property and facilities bearing interest at 8.25% per annum with semiannual payments of principal and interest through June 2019. The principal balance outstanding on the mortgage note aggregated $5.2 million at December 31, 2015. The mortgage note is collateralized by the Largo, Florida property and facilities.
