During the six months ended December 31, 2014, we received $6.1 million of landlord-funded leasehold improvements related to our new principal executive offices located in Bedford, Massachusetts. The landlord-funded leasehold improvements are recorded as property, plant and equipment and deferred rent in our unaudited consolidated balance sheets as of December 31, 2014. The landlord-funded leasehold improvements were recorded as deferred rent and will be amortized as a reduction to rent expense over the life of the lease. During fiscal 2014, we made $1.5 million of improvements to the Bedford, Massachusetts offices that were determined to be owned by the landlord. As of June 30, 2014, the $1.5 million of improvements were recorded within other non-current assets in our consolidated balance sheets and reclassified as a reduction to deferred rent during the second quarter of fiscal 2015. The $1.5 million of improvements will be amortized as additional rent expense over the life of the lease. Please refer to Note 11 for further information on the lease.

Other is comprised primarily of our net reserve for uncertain tax liabilities of $23.7 million and $9.3 million as of December 31, 2014 and June 30, 2014, respectively. We account for unrecognized tax benefits in accordance with ASU No. 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. In accordance with ASU 2013-11, deferred tax assets should be presented net of liabilities for uncertain tax positions provided there are specific deferred tax assets available to settle the uncertain income tax liabilities. As of June 30, 2014, we had sufficient deferred tax assets available to settle a portion of our reserve for uncertain tax positions, and consequently, a only a portion of our total reserve for uncertain tax positions was reported as a non-current liability in our consolidated balance sheets. As of December 31, 2014, we no longer had deferred tax assets available to net against our reserve for uncertain tax positions and the total reserve for uncertain tax liabilities is reported as a non-current liability. Our total reserve for uncertain tax positions was approximately $24.0 million as of December 31, 2014 and June 30, 2014.
