7. Commitments and Contingencies

Leases

The Company leases its buildings under operating leases that expire on various dates through 2022. Future minimum annual lease payments under such leases as of December 31, 2016 are as follows (in thousands):

Year Ending December 31,	Operating
2017	$	2,364
2018		2,387
2019		1,998
2020		1,702
2021		1,705
Beyond		33
Total	$	10,189

As of December 31, 2016, $4.0 million of the remaining lease commitments expense has been accrued as part of the 2013 Restructuring Plan, partially offset by future estimated sublease income of $2.1 million.

Total rent expense was $1.6 million, $1.3 million and $1.2 million for the years ended December 31, 2016, 2015, and 2014, respectively.

As a condition of our lease in Pittsburgh, the landlord agreed to incentives of $40.00 per square foot, or a total of $2.2 million, for improvements to the space. These costs have been included in deferred rent in our long-term liabilities and are being amortized over the remaining lease term.

Pennsylvania Opportunity Grant Program

On September 26, 2011, we received $1.0 million from the State of Pennsylvania to help fund our agreement to start-up a new facility. The grant carried with it an obligation, or commitment, to employ at least 232 people within a three-year time period that ended on December 31, 2013. We received an extension of time to meet this employment commitment by April 30, 2016. The grant contained conditions that would require us to return a pro-rata amount of the monies received if we failed to meet these conditions. As such, the monies had been recorded as a liability in the accrued liabilities line item on the balance sheet until we are irrevocably entitled to retain the monies, or until it is determined that we need to return a portion or all of the monies received. On June 27, 2016, we received a letter from the State of Pennsylvania requesting reimbursement of $0.3 million and said we earned the remaining $0.7 million of the original $1.0 million grant. On September 19, 2016, we entered into a Settlement and Release Agreement with the Commonwealth of Pennsylvania, acting by and through the Department of Community and Economic Development (“DCED”) to repay $0.3 million of the original $1.0 million grant. Per the agreement, the total amount due of $0.3 million is at 0% interest and is payable in twenty equal quarterly installments commencing on January 31, 2017 and ending on October 31, 2021.

Litigation

The Company may become involved in various legal proceedings arising from its business activities. While management does not believe the ultimate disposition of these matters will have a material adverse impact on the Company’s consolidated results of operations, cash flows, or financial position, litigation is inherently unpredictable, and depending on the nature and timing of these proceedings, an unfavorable resolution could materially affect the Company’s future consolidated results of operations, cash flows, or financial position in a particular period.

Other Contingent Contractual Obligations

During its normal course of business, the Company has made certain indemnities, commitments, and guarantees under which it may be required to make payments in relation to certain transactions. These include: intellectual property indemnities to the Company’s customers and licensees in connection with the use, sale and/or license of Company products; indemnities to various lessors in connection with facility leases for certain claims arising from such facility or lease; indemnities to vendors and service providers pertaining to claims based on the negligence or willful misconduct of the Company; indemnities involving the accuracy of representations and warranties in certain contracts; and indemnities to directors and officers of the Company to the maximum extent permitted under the laws of the State of Delaware. In addition, the Company has made contractual commitments to employees providing for severance payments upon the occurrence of certain prescribed events. The Company may also issue a guarantee in the form of a standby letter of credit as security for contingent liabilities under certain customer contracts. The duration of these indemnities, commitments, and guarantees varies, and in certain cases, may be indefinite. The majority of these indemnities, commitments and guarantees may not provide for any limitation of the maximum potential for future payments the Company could be obligated to make. The Company has not recorded any liability for these indemnities, commitments, and guarantees in the accompanying consolidated balance sheets.
