Schedule of amounts in accumulated other comprehensive loss (gain) to be recognized over next fiscal year | We amortize the unrecognized prior service credit using a straight-line method over the average remaining service period of the employees we expect to receive benefits under the plan. We amortize the unrecognized net actuarial loss (gain), which is subject to certain averaging conventions, over the average remaining service period of active employees. The following table shows the amounts we expect to recognize as components of net periodic cost in 2015 from amounts recorded in accumulated comprehensive loss (gain) as of December 31, 2014 (in millions):

Expected long term return on assets and to measure the periodic cost | We use the following assumptions to measure the benefit obligation, compute the expected long-term return on assets, and measure the periodic cost for our defined benefit pension plans and other post-retirement benefit plans for the years ended December 31:

Review of historical returns | We calculate the present value of expected future pension and post-retirement cash flows as of the measurement date using a discount rate. We base the discount rate on yields for high-quality, long-term bonds with durations similar to that of our projected benefit obligation. We base the expected return on our plan assets on current and expected asset allocations, as well as historical and expected returns on various categories of plan assets. We routinely review our historical returns along with current market conditions to ensure our expected return assumption is reasonable and appropriate.

__________________ (1)Our contributions represented more than 5% of the total contributions to the plan during each year and no surcharge was imposed for any year. The actuary for the American Maritime Officers Pension Plan certified that the plan is in endangered status (i.e. “yellow zone” as defined by the Pension Protection Act of 2006) for the plan year beginning October 1, 2013, because it has funding or liquidity problems, or both. A rehabilitation plan, as defined by the Employee Retirement Security Act of 1974, was instituted under which certain adjustable benefits were reduced or eliminated, and we are required to contribute at a negotiated rate per day worked by each employee.

Disclosure also typically includes the amount of related compensation expense recognized during the reporting period and the carrying amount as of the balance sheet date of the related liability. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -SubTopic 10 -Section 30 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6409875&loc=d3e20015-108363 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -SubTopic 10 -Section 25 -Paragraph 9 -URI http://asc.fasb.org/extlink&oid=6409733&loc=d3e19512-108361 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 710 -SubTopic 10 -Section 55 -Paragraph 7 -URI http://asc.fasb.org/extlink&oid=6409961&loc=d3e20487-108367 + Details
