Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | COMMITMENTS AND CONTINGENCIES Operating Leases Acacia leases certain office space under various operating lease agreements expiring at various dates from 2019 through 2020. Minimum annual rental commitments for operating leases of continuing operations having initial or remaining noncancellable lease terms in excess of one year are as follows (in thousands):
Years ending December 31, |
2018 | $ | 1,213 |
2019 | 1,369 |
2020 | 16 |
Total minimum lease payments | $ | 2,598 |
Rent expense for the years ended December 31, 2017, 2016 and 2015 approximated $1,392,000, $1,795,000 and $1,926,000, respectively. Rental payments are expensed in the statements of operations in the period to which they relate. Scheduled rent increases are amortized on a straight-line basis over the lease term. Inventor Royalties and Contingent Legal Expenses In connection with the investment in certain patents and patent rights, certain of Acacia’s operating subsidiaries executed related agreements which grant to the former owners of the respective patents or patent rights, the right to receive inventor royalties based on future net revenues (as defined in the respective agreements) generated as a result of licensing and otherwise enforcing the respective patents or patent portfolios. Acacia’s operating subsidiaries may retain the services of law firms that specialize in patent licensing and enforcement and patent law in connection with their licensing and enforcement activities. These law firms may be retained on a contingent fee basis whereby such law firms are paid on a scaled percentage of any negotiated fees, settlements or judgments awarded based on how and when the fees, settlements or judgments are obtained. Patent Enforcement and Other Litigation Acacia is subject to claims, counterclaims and legal actions that arise in the ordinary course of business. Management believes that the ultimate liability with respect to these claims and legal actions, if any, will not have a material effect on Acacia’s consolidated financial position, results of operations or cash flows. Fiscal year 2017 includes estimated contingency accruals totaling $1,200,000. The estimated range of potential expenses related to these matters is $1,200,000 to $3,000,000. Fiscal year 2016 and 2015 operating expenses included expenses for court ordered attorney fees and settlement and contingency accruals totaling $500,000 and $4,141,000, respectively. Guarantees and Indemnifications Certain of Acacia’s operating subsidiaries have made guarantees and indemnities under which they may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions, including revenue transactions in the ordinary course of business. In connection with certain facility leases, Acacia and certain of its operating subsidiaries have indemnified lessors for certain claims arising from the facilities or the leases. Acacia indemnifies its directors and officers to the maximum extent permitted under the laws of the State of Delaware. However, Acacia has a directors and officers insurance policy that may reduce its exposure in certain circumstances and may enable it to recover a portion of future amounts that may be payable, if any. The duration of the guarantees and indemnities varies and, in many cases is indefinite but subject to statute of limitations. The majority of guarantees and indemnities do not provide any limitations of the maximum potential future payments that Acacia could be obligated to make. To date, Acacia has made no payments related to these guarantees and indemnities. Acacia estimates the fair value of its indemnification obligations to be insignificant based on this history and therefore, have not recorded any liability for these guarantees and indemnities in the accompanying consolidated balance sheets. Additionally, no events or transactions have occurred that would result in a material liability at December 31, 2017. Bank Guarantee In March 2015, an operating subsidiary of Acacia entered into a standby letter of credit and guarantee arrangement (“Guarantee”) with a bank for purposes of enforcing a court ruling in a German patent court granting an injunction against the defendants in the related patent infringement case. The Guarantee was secured by a cash deposit at the contracting bank, which was classified as restricted cash in the accompanying December 31, 2016 consolidated balance sheets, totaling $11,512,000. Upon resolution of all related matters in June 2017, the Guarantee was extinguished resulting in release of the cash collateral (and related restrictions on the cash balance) by the contracting bank. As a result, currently no amounts of Acacia’s cash and investments are restricted as to use. Other In August 2010, a wholly owned subsidiary of Acacia became the general partner of the Acacia IP Fund, which was formed in August 2010. The Acacia IP Fund invests in, licenses and enforces intellectual property consisting primarily of patents, patent rights, and patented technologies. The Acacia IP Fund was terminated as of December 31, 2017. At December 31, 2017 and 2016, the Acacia IP Fund net assets and net income (loss) were primarily comprised of the following (in thousands):
