Commitments and Contingencies

Operating and Capital Lease Commitments

The Company leases office space for its corporate headquarters in Austin, Texas under a non-cancelable operating lease that expires in April 2021 and a regional sales office in Atlanta, Georgia under a non-cancelable operating lease that expires in January 2016. In addition, the Company leases office space for its previous corporate headquarters in Austin, Texas under a non-cancelable operating lease that expires in March 2015. All of the rentable space covered by this lease has been sublet to a tenant for substantially all of the remainder of the lease. Rent expense under operating leases was $1.0 million, $1.4 million, and $0.9 million for the years ended December 31, 2014, 2013 and 2012, respectively. In 2013, the Company moved to its current headquarters. As a result, the Company vacated its former leased headquarters and recorded an estimated unoccupied lease charge of $0.2 million for the remaining contractual lease payments less estimated sublease income.

New Facilities Lease

On July 18, 2014, the Company entered into an office lease agreement, or the Lease, with CREF Aspen Lake Building II, LLC to lease approximately 70,000 rentable square feet, or the Premises, of an office building to be located immediately adjacent to the Company's current headquarters in order to expand the Company's headquarters. The Lease provides for phased commencement dates, with commencement of the first phase covering approximately 55,000 rentable square feet anticipated to occur on November 1, 2015, or the Initial Commencement Date, with the remaining space becoming available nine months thereafter. The actual commencement dates are subject to timely completion of the construction of the Premises. The term of the Lease commences on the Initial Commencement Date and runs 124 months, with a five year renewal option, and the rent obligations under the Lease begin with rents of $98 per month, which escalate over the course of the Lease to $160 per month in the final four months of the Lease's term.

The Company has entered into various capital lease arrangements to obtain property and equipment for its data center and corporate operations. These agreements expire over various terms from March 2015 through May 2025 and the leases are secured by the underlying leased property and equipment.
