The Company is considered the owner, for accounting purposes only, of one of its Santa Monica, California leased office spaces and of its San Francisco, California leased office space (collectively, the “Premises”) as it has taken on certain risks of construction build cost overages above normal tenant improvement allowances. Accordingly, at June 30, 2015 and December 31, 2014, the Company has capitalized $29.7 million and $6.6 million, respectively, related to the Premises, which represents the estimated fair value of the leased properties and additions for capitalized interest incurred during the construction periods and capitalized costs related to structural improvements to the building. For the three and six months ended June 30, 2015, the Company capitalized approximately $0.5 million and $1.2 million of interest costs related to the Premises, respectively. Additionally, at June 30, 2015 and December 31, 2014, the Company recognized a corresponding lease financing obligation of approximately $28.4 million and $6.6 million, respectively. Refer to Note 7 for additional information. Normal leasehold improvements related to the facilities are recorded in leasehold improvements in the table above.

Included in the table above are property and equipment of $24.4 million and $8.1 million at June 30, 2015 and December 31, 2014, respectively, which are capitalizable, but had not yet been placed in service. The $24.4 million balance at June 30, 2015 was comprised primarily of the Santa Monica capitalized facility lease of $22.6 million. The $8.1 million balance at December 31, 2014 was comprised primarily of the San Francisco capitalized facility lease of $6.6 million.
