Total expense under non-cancelable operating lease commitments, primarily for offices, motor vehicles and office equipment was $9.2 million, $9.4 million and $9.5 million for the years ended December 31, 2014, 2013 and 2012, respectively.

Rental payments applicable to such operating leases are recognized on a straight-line basis over the term of the lease.

We have orders with Meyer Werft for four Breakaway Plus Class Ships for delivery in the fall of 2015, spring of 2017, spring of 2018 and fall of 2019. These ships will be the largest in our fleet, reaching approximately 164,600 Gross Tons and up to 4,200 Berths each and will be similar in design and innovation to our Breakaway Class Ships. The combined contract price of these four ships is approximately €3.0 billion, or $3.6 billion based on the euro/U.S. dollar exchange rate as of December 31, 2014. We have export credit financing in place that provides financing for 80% of their contract prices. We also have a contract with Italy’s Fincantieri shipyard to build a luxury cruise ship to be named Seven Seas Explorer. The contract price of the ship is approximately €343.0 million, or approximately $415.0 million, based on the euro/U.S. dollar exchange rate as of December 31, 2014. We have export credit financing in place that provides financing for 80% of the ship’s contract price. Seven Seas Explorer is expected to be delivered in the summer of 2016.

In connection with the contracts to build the ships, we do not anticipate any contractual breaches or cancellation to occur. However, if any would occur, it could result in, among other things, the forfeiture of prior deposits or payments made by us and potential claims and impairment losses which may materially impact our business, financial condition and results of operations.

As of December 31, 2014, future commitments to pay for usage of certain port facilities were as follows (in thousands):

The FMC requires evidence of financial responsibility for those offering transportation on passenger ships operating out of U.S. ports to indemnify passengers in the event of non-performance of the transportation. Accordingly, each of our three brands are required to maintain a $22.0 million third-party performance guarantee in respect of liabilities for non-performance of transportation and other obligations to passengers. Recent regulations have revised the financial requirements with respect to both death/injury and non-performance coverages to increase the current $22.0 million performance guarantee to $30.0 million effective April 2, 2015. Once fully effective in April 2015, the guarantee requirements will be subject to additional consumer price index-based adjustments. We do not anticipate that compliance with the new rules will have a material effect on our costs. Also, each of our brands have a legal requirement to maintain a security guarantee based on cruise business originated from the U.K. and, accordingly, have established separate bonds with the Association of British Travel Agents currently valued at British Pound Sterling 8.0 million in the aggregate. We also are required to establish financial responsibility by other jurisdictions to meet liability in the event of non-performance of our obligations to passengers from those jurisdictions.

From time to time, various other regulatory and legislative changes have been or may in the future be proposed that may have an effect on our operations in the U.S. and the cruise industry in general.

In July 2009, a class action complaint was filed against NCL (Bahamas) Ltd., in the United States District Court, Southern District of Florida, on behalf of a purported class of crew members alleging inappropriate deductions of their wages pursuant to the Seaman’s Wage Act and wrongful termination resulting in a loss of retirement benefits. In December 2010, the Court denied the plaintiffs’ Motion for Class Certification. In February 2011, the plaintiffs filed a Motion for Reconsideration of the Court’s Order on Class Certification which was denied. The Court tried six individual plaintiffs’ claims, and in September 2012 awarded wages aggregating approximately $100,000 to such plaintiffs. In October 2013, the United States Court of Appeals for the Eleventh Circuit affirmed the Court’s rulings as to the denial of class certification and the trial verdict. The plaintiffs filed a petition for a writ of certiorari in the United States Supreme Court seeking review of the appellate court decision which was denied in March 2014. The matter was ordered to mediation on October 2014. At that time, all outstanding claims brought on behalf of the known plaintiffs were resolved.

In May 2011, a class action complaint was filed against NCL (Bahamas) Ltd., in the United States District Court, Southern District of Florida, on behalf of a purported class of crew members alleging inappropriate deductions of their wages pursuant to the Seaman’s Wage Act and breach of contract. In July 2012, this action was stayed by the Court pending the outcome of the litigation commenced with the class action complaint filed in July 2009. The matter was resolved at the Court ordered mediation in conjunction with the matter described above.

In the normal course of our business, various other claims and lawsuits have been filed or are pending against us. Most of these claims and lawsuits are covered by insurance and, accordingly, the maximum amount of our liability is typically limited to our deductible amount. Nonetheless, the ultimate outcome of these claims and lawsuits that are not covered by insurance cannot be determined at this time. We have evaluated our overall exposure with respect to all of our threatened and pending litigation and, to the extent required, we have accrued amounts for all estimable probable losses associated with our deemed exposure. We are currently unable to estimate any other potential contingent losses beyond those accrued, as discovery is not complete nor is adequate information available to estimate such range of loss or potential recovery. We intend to vigorously defend our legal position on all claims and, to the extent necessary, seek recovery.
