7. Mortgages Payable

During 2013, we assumed mortgages totaling $630.0 million, excluding net premiums. The mortgages are secured by the properties on which the debt was placed. Of the $630.0 million of mortgages assumed during 2013, approximately $608.8 million is considered non-recourse with limited customary exceptions for items such as bankruptcy, misrepresentation, fraud, misapplication of payments, environmental liabilities, failure to pay taxes, insurance premiums, liens on the property and uninsured losses. Approximately $6.6 million has full recourse to Realty Income, and the remaining $14.6 million of the assumed debt is not guaranteed by and is non-recourse to Realty Income. We expect to pay off the mortgages as soon as prepayment penalties have declined to a level that will make it economically feasible to do so. We intend to continue to primarily identify property acquisitions that are free from mortgage indebtedness. We repaid four mortgages in full during 2013, including one in August for $11.7 million and three in December for $23.1 million. One of the mortgages repaid in December was related to a mortgage previously assumed during 2013.

During 2013, aggregate net premiums totaling $28.4 million were recorded upon assumption of the mortgages for above-market interest rates, as compared to net premiums totaling $10.0 million recorded in 2012. Amortization of these net premiums is recorded as a reduction to interest expense over the remaining term of the respective mortgages, using a method that approximates the effective-interest method.

These mortgages contain customary covenants, such as limiting our ability to further mortgage each applicable property or to discontinue insurance coverage, without the prior consent of the lender. At December 31, 2013, we remain in compliance with these covenants.

As a result of assuming mortgages payable, we incurred deferred financing costs of $211,000 in 2013 and $1.1 million in 2012, which are classified as part of other assets, net, on our consolidated balance sheets. The balance of these deferred financing costs was $1.2 million at December 31, 2013 and $1.5 million at December 31, 2012 which is being amortized over the remaining term of each mortgage.

The following is a summary of all our mortgages payable as of December 31, 2013 and 2012, respectively (dollars in thousands):

(1) At December 31, 2013, there were 47 mortgages on 227 properties, while at December 31, 2012, there were 13 mortgages on 11 properties. The mortgages require monthly payments, with principal payments due at maturity. The mortgages are at fixed interest rates, except for: (1) a $23.6 million mortgage maturing on June 10, 2015 with a floating variable interest rate calculated as the sum of the current one month LIBOR plus 4.5%, not to exceed an all-in interest rate of 5.5%, (2) a $8.3 million mortgage maturing on September 3, 2021, with a floating interest rate calculated as the sum of the current one month LIBOR plus 2.4%, and (3) a $32.4 million mortgage maturing on April 10, 2017, which is fixed at 5.07% through December 28, 2015, but is reset to the greater of 4.0%, or the two-year swap rate plus 2.75% thereafter. As part of the $8.3 million mortgage payable assumed in 2012, we also acquired an interest rate swap which essentially fixes the interest rate on this mortgage payable at 6.0%. As part of the $32.4 million mortgage payable assumed in 2013, we have the opportunity to prepay the mortgage at par on December 28, 2015, prior to the variable interest rate reset. As part of two mortgages totaling $8.8 million that matured on December 28, 2013, we also acquired an $8.8 million note receivable, upon which we received interest income at a stated rate of 8.1% through December 28, 2013.

(2) Stated interest rates ranged from 2.5% to 6.9% at December 31, 2013, while stated interest rates ranged from 2.6% to 8.3% at December 31, 2012.

(3) Effective interest rates ranged from 2.4% to 9.2% at December 31, 2013, while effective interest rates ranged from 2.7% to 8.3% at December 31, 2012.
