The grounding resulted in a breach of a portion of the Nathan E. Stewart&#8217;s fuel tanks causing a discharge of diesel fuel into the water. The USCG and the National Transportation Safety Board designated the Company as a party of interest in their investigation as to the cause of the incident.

The amendment included a provision for the continued vesting of unvested stock options and RSUs for employees who meet certain years of service and age requirements at the time of their retirement. The vesting change resulted in shorter expense accrual periods on stock options and RSUs granted after February 19, 2018 to employees who are nearing retirement and meet the service and age requirements.</font></div><div style="text-align: left;"><font style="font-size: 10pt; font-family: 'Times New Roman';"></font><br /></div><div style="text-align: justify; text-indent: 18pt;"><font style="font-size: 10pt; font-family: 'Times New Roman';">The exercise price for each option equals the fair market value per share of the Company&#8217;s common stock on the date of grant.

The director plan provides for automatic grants of restricted stock to nonemployee directors after each annual meeting of stockholders. In addition, the director plan allows for the issuance of stock options or restricted stock in lieu of cash for all or part of the annual director fee at the option of the director. The exercise prices for all options granted under the plan are equal to the fair market value per share of the Company&#8217;s common stock on the date of grant. The terms of the options are ten years. The restricted stock issued after each annual meeting of stockholders vests six months after the date of grant. Options granted and restricted stock issued in lieu of cash director fees vest in equal quarterly increments during the year to which they relate. At March 31, 2019, 486,058 shares were available for future grants under the director plan. The director stock award plan is intended as an incentive to attract and retain qualified independent directors.</font></div><div style="text-align: justify;"><font style="font-size: 10pt; font-family: 'Times New Roman';"></font><br /></div><div style="text-align: justify;

The Credit Agreement provides for a variable interest rate based on the London interbank offered rate (&#8220;LIBOR&#8221;) or a base rate calculated with reference to the agent bank&#8217;s prime rate, among other factors (the &#8220;Alternate Base Rate&#8221;).&#160; The interest rate varies with the Company&#8217;s credit rating and is currently 112.5 basis points over LIBOR or 12.5 basis points over the Alternate Base Rate.&#160; The Term Loan is repayable in quarterly installments commencing June 30, 2020, in increasing percentages of the original principal amount of the loan, with the remaining unpaid balance payable of 65% of the initial amount due on March 27, 2024.&#160; The Credit Agreement contains certain restricted financial covenants including an interest coverage ratio and a debt-to-capitalization ratio.&#160; In addition to financial covenants, the Credit Agreement contains covenants that, subject to exceptions, restrict debt incurrence, mergers and acquisitions, sales of assets, dividends and investments, liquidations and dissolutions, capital leases, transactions with affiliates and changes in lines of business.&#160; The Credit Agreement specifies certain events of default, upon the occurrence of which the maturity of the outstanding loans may be accelerated, including the failure to pay principal or interest, violation of covenants and default on other indebtedness, among other events.&#160; Borrowings under the Credit Agreement may be used for general corporate purposes including acquisitions.&#160; As of March 31, 2019, the Company was in compliance with all Credit Agreement covenants and had outstanding borrowings under the Revolving Credit Facility of $176,574,000 and $500,000,000 outstanding under the Term Loan.&#160; The Revolving Credit Facility includes a $25,000,000 commitment which may be used for standby letters of credit.&#160; Outstanding letters of credit under the Revolving Credit Facility were $6,400,000 as of March 31, 2019.</font></div></div> 1667457000 1410169000 3072000 3114000 256175000 426931000 44177000 32315000 -458757000 -295215000 44177000 32315000 161000 195000 18734000 38529000 32471000 44296000 <div style="font-family: 'Times New Roman';

Retirement Benefits - Defined Benefit Plans &#8211; General (Subtopic 715-20): Disclosure Framework &#8211; Changes to the Disclosure Requirements for Defined Benefit Plans&#8221; which amends the annual disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing certain requirements, providing clarification on existing requirements and adding new requirements including adding an explanation of the reasons for significant gains and losses related to changes in the benefit obligation for the period. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted. The amendments in this update are required to be applied on a retrospective basis to all periods presented. The Company is currently evaluating this guidance to determine the impact on its disclosures.</font></div><div style="text-align: left;"><font style="font-size: 10pt; font-family: 'Times New Roman';"></font><br /></div><div style="text-align: justify; text-indent: 18pt;"><font style="font-size: 10pt; font-family: 'Times New Roman';">In January 2017, the FASB issued ASU 2017-04, &#8220;Intangibles &#8211; Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment&#8221; (&#8220;ASU 2017-04&#8221;) which simplifies the subsequent measurement of goodwill by eliminating Step 2 in the goodwill impairment test that required an entity to perform procedures to determine the fair value of its assets and liabilities at the testing date. An entity instead will perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying value and record an impairment charge based on the excess of a reporting unit&#8217;s carrying amount over its fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. ASU 2017-04 will be applied prospectively and is effective for annual and interim goodwill impairment tests conducted in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment testing dates after January 1, 2017. The Company is currently evaluating the impact, if any, that the adoption of this standard will have on its consolidated financial statements.</font></div><div><br /></div><div style="text-align: justify; text-indent: 18pt;"><font style="font-size: 10pt; font-family: 'Times New Roman';">In February 2016, the FASB issued ASU No. 2016-02, &#8220;Leases (Topic 842)&#8221; (&#8220;ASU 2016-02&#8221;) to increase transparency and comparability among organizations by requiring recognition of lease assets and lease liabilities on the balance sheet and disclosure of key information about leasing arrangements. The Company adopted ASU 2016-02 on January 1, 2019 under the optional transition method that allows for a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption and will not restate prior periods.&#160; The Company also elected certain practical expedients permitted under the transition guidance which allows the Company to carryforward its historical lease classification and for the non-recognition of short-term leases. Adoption of ASU 2016-02 resulted in the recognition of operating lease right-of-use assets for operating leases of $168,149,000 and lease liabilities for operating leases of $175,778,000 on the Company&#8217;s Condensed Balance Sheets as of January 1, 2019, with no material impact to the Condensed Statements of Earnings or Cash Flows.
