Year Ended |  | Aggregate Square Footage |  | Weighted Average Lease Term |  | Aggregate Purchase Price |  | Acquisition Costs |  | Aggregate Annualized GAAP Rent |  | Aggregate Debt Issued or Assumed |
December 31, 2017 | (1) | 871,038 |  |  | 10.1 Years |  | $ | 132,157 |  |  | $ | 1,356 |  | (3) | $ | 15,507 |  |  | $ | 54,887 |  | (4)

(1) | On June 22, 2017, we acquired a 60,016 square foot property in Conshohocken, Pennsylvania for $15.7 million. We assumed $11.2 million of mortgage debt in connection with this acquisition. The annualized GAAP rent on the 8.5 year lease is $1.7 million. On July 7, 2017, we acquired a 300,000 square foot property in Philadelphia, Pennsylvania for $27.1 million. We issued $14.9 million of mortgage debt with a fixed interest rate of 3.75% in connection with this acquisition. The annualized GAAP rent on the 15.4 year lease is $2.3 million. On July 31, 2017, we acquired a 306,435 square foot three property portfolio located in Maitland, Florida for $51.6 million. We issued $28.8 million of mortgage debt with a fixed interest rate of 3.89% in connection with this acquisition. This portfolio has a weighted average lease term of 8.6 years, and annualized GAAP rent of $6.8 million. On December 1, 2017, we acquired a 102,559 square foot property in Columbus, Ohio for $17.3 million. The annualized GAAP rent on the weighted average 6.9 year leases is $1.7 million. On December 1, 2017, we acquired a 102,028 square foot property in Salt Lake City, Utah for $20.5 million. The annualized GAAP rent on the 10.1 year lease is $3.0 million.
(2) | On May 26, 2016, we acquired a 107,062 square foot property in Salt Lake City, Utah for $17.0 million. We borrowed $9.9 million to fund the acquisition. The annualized GAAP rent on the 6.0 year lease is $1.4 million. On September 12, 2016 we acquired a 119,224 square foot property in Fort Lauderdale, Florida for $23.9 million. We borrowed $14.1 million to fund the acquisition. The annualized GAAP rent on the 9.0 year lease is $2.0 million. On December 14, 2016, we acquired a 103,334 square foot property in King of Prussia, Pennsylvania for $25.7 million, including $0.2 million of acquisition-related costs that were allocated among the identifiable assets acquired. These acquisition-related costs are not included in the aggregated costs in the table above. We borrowed $14.8 million to fund the acquisition. The annualized GAAP rent on the 15.0 year lease is $2.2 million. Our King of Prussia, PA acquisition in the fourth quarter was accounted for as an asset acquisition under ASC 360.
(3) | We adopted ASU 2017-01 during the quarter ended December 31, 2016. As a result, we treated our acquisitions during the year ended December 31, 2017 as asset acquisitions rather than business combinations. As a result of this treatment, we capitalized $1.4 million of acquisition costs that would otherwise have been expensed under business combination treatment.
(4) | We assumed an interest rate swap in connection with $11.2 million of assumed debt on our Conshohocken, Pennsylvania acquisition, pursuant to which we will pay our counterparty a fixed interest rate of 1.80%, and receive a variable interest rate of one month LIBOR from our counterparty. Our total interest rate is fixed at 3.55%. The interest rate swap had a fair value of $0.04 million upon the date of assumption, and subsequently increased in value to $0.3 million at December 31, 2017. We have elected to treat this interest rate swap as a cash flow hedge, and all changes in fair market value will be recorded to accumulated other comprehensive income on the consolidated balance sheets.
