Off-Balance Sheet Arrangements and Contractual Obligations Effect of Recent Accounting Pronouncements Subsequent Events We do not have off-balance sheet financing arrangements and have not engaged in any related party transactions or arrangements with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of or requirements for capital resources.  We have various contractual obligations and commercial commitments. The following table sets forth, in millions, the annual payments we are required to make under contractual cash obligations and other commercial commitments at  December 31, 2013. Contractual Obligations We are required to make payments necessary to pay the interest on the Taxable Revenue Bond, Series 1995, as amended,  currently outstanding in the aggregate principal amount of $46.5 million. The bond matures on January 1, 2020, and bears  interest at the rate of 5% per annum. Included in long-term investments are $48.3 million of restricted funds, which is a collateral deposit against the principal amount of this bond. We did not make a principal payment for the year-ended December 31, 2013. We made a principal payment of $0.5 million for the year ended December 31, 2012. We anticipate making a principal payment in 2014. At December 31, 2013 and 2012, $0.3 million and $0.5 million, respectively, of the bond debt were classified as a current liability in accounts payable in the Consolidated Balance Sheets at December 31, 2013.  See Note 9 of Notes to Consolidated Financial Statements for additional information. We have committed to invest up to an aggregate of $7.9 million in two private equity funds, and we have contributed $8.4 million as of December 31, 2013, of which $7.7 million has been applied to these commitments. The additional $0.2 million commitment has been excluded from the table above due to uncertainty of when it will be applied. We also have obligations related to uncertain income tax positions that have been excluded from the table above due to the uncertainty of when the related expense will be recognized. See Note 10 of Notes to Consolidated Financial Statements for additional information. During 2013, we adopted the following accounting standards, which had no material effect on our consolidated results of  operations or financial condition: In February 2013, the FASB issued Accounting Standards Update No. 2013-02, Reporting of Amounts Reclassified Out  of Accumulated Other Comprehensive Income (ASU 2013-02). ASU 2013-02 requires entities to provide information about  the amounts reclassified out of accumulated other comprehensive income by component either on the face of the financial  statements or in the footnotes. ASU 2013-02 does not change the current requirements for reporting net income or other  comprehensive income in the financial statements. This update is effective prospectively for reporting periods beginning  after December 15, 2012. We adopted this amendment during the first quarter of 2013, and we have provided the disclosures  required for the years ended December 31, 2013, 2012 and 2011 in Note 1 of Notes to Consolidated Financial Statements. On January 21, 2014, the Board declared a quarterly cash dividend of $0.09 per common share to be paid to shareholders of record at the close of business on February 6, 2014. The quarterly dividend payment was $5.1 million and was paid on  February 20, 2014. In February 2014, we made a decision to make a $16.5 million principal payment on the Amended and Restated Bond.  The restricted certificate of deposit included in our long-term investments will be reduced by the amount of the payment. We anticipate this payment will be made during the first quarter of 2014. Since January 1, 2014 and as of February 27, 2014, we have repurchased 0.4 million shares of our common stock through  open market purchases at an average cost of $25.13 per share. We currently have the authority to purchase an additional 3.1 million shares of our common stock under the current plan approved by the Board of Directors.
