Debt [Abstract]
Debt	Note 9. DEBT In June 2014, we refinanced our existing $450.0 million unsecured revolving credit facility by entering into an amended and restated credit agreement relating to a five-year unsecured revolving credit facility in the principal amount of $700 million with a syndicate of multinational banks, which matures on June 18, 2019 (the new credit facility and the previous credit facility are referred to collectively as the “Credit Facility”) and requires no scheduled prepayments before that date. Although the Credit Facility does not mature until June 18, 2019, all amounts borrowed under the terms of the Credit Facility are reflected in the current liabilities section in the accompanying condensed consolidated balance sheets because the Credit Facility contains a subjective material adverse event clause, which allows the debt holders to call the loans under the Credit Facility if we fail to provide prompt written notice to the syndicate of such an event. At September 30, 2014 and December 31, 2013, we had $375.0 million and $277.0 million, respectively, outstanding under the Credit Facility with a weighted average effective interest rate of 1.6%. The funds available under the Credit Facility at September 30, 2014 and December 31, 2013 reflect a further reduction due to the issuance of a letter of credit for $1.0 million, which was issued in connection with our workers’ compensation policy. Applicable interest rates on borrowings under the Credit Facility generally range from 0.875 to 1.375 percentage points (“Credit Spread”) above the London interbank offered rate or the Canadian Dollar-denominated bankers’ acceptance rate, based on our leverage ratio, or the prevailing prime rate plus a maximum spread of up to 0.375%, based on our leverage ratio. We have entered into forward fixed interest rate swap agreements to manage the economic effect of the first $80 million of variable interest rate borrowings. As such, we continue to designate the existing interest rate swaps as cash flow hedges. See Note 17 for a discussion of our derivative instruments and hedging activities. Under the Credit Facility, we pay quarterly commitment fees of 0.15% to 0.35%, based on our leverage ratio, on any unused commitment. The obligations under the Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default, including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness and a change of control default. The Credit Facility contains affirmative, negative and financial covenants customary for financings of this type. The negative covenants include restrictions on liens, indebtedness of subsidiaries of the Company, fundamental changes, investments, transactions with affiliates and certain restrictive agreements. The financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization and share-based compensation, defined as the consolidated leverage ratio under the terms of the Credit Facility, not to exceed 3.5-to-1. At September 30, 2014, we were in compliance with the covenants of the Credit Facility. In December 2013, we issued and sold through a private placement an aggregate principal amount of $150 million of senior notes consisting of $75 million of 3.94% Series A Senior Notes due December 11, 2023 (the “2023 Notes”) and $75 million of 4.04% Series B Senior Notes due December 11, 2025 (the “2025 Notes” and together with the 2023 Notes, the “December Notes”) under a Note Purchase Agreement among the Company, New York Life Insurance Company and the accredited institutional purchasers named therein (the “December 2013 Note Agreement”). In July 2014, we issued and sold through a private placement an aggregate principal amount of $125 million of senior notes consisting of $75 million of 3.76% Series B Senior Notes due July 21, 2024 (the “2024 Notes”) and $50 million of 3.32% Series A Senior Notes due July 21, 2021 (the “2021 Notes” and together with the 2024 Notes, the “Prudential Notes”) under a Note Purchase and Private Shelf Agreement among the Company, Prudential Investment Management, Inc. and the accredited institutional purchasers named therein (the “July 2014 Note Agreement”). In September 2014, we issued and sold through a private placement an aggregate principal amount of $75 million of 3.72% Senior Notes due September 4, 2026 (the “2026 Notes” and together with the Prudential Notes and the December Notes, the “Senior Notes”) under a Note Purchase Agreement dated as of July 22, 2014 among the Company, New York Life Insurance Company and the accredited institutional purchasers named therein (such agreement, together with July 2014 Note Agreement and December 2013 Note Agreement, the “Senior Note Agreements”). The Senior Note Agreements contain affirmative, negative and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements and violations of laws and regulations. The financial covenant is a consolidated leverage ratio test that requires our ratio of debt to earnings before interest, taxes, depreciation, amortization and share-based compensation, as defined in the Senior Note Agreements, not to exceed 3.5-to-1. At September 30, 2014, we were in compliance with the covenants of the Senior Note Agreements. Should we elect to prepay the Senior Notes, such aggregate prepayment will include the applicable make-whole amount(s), as defined within the applicable Senior Note Agreements. Additionally, in the event of a change in control of the Company or upon the disposition of certain assets of the Company the proceeds of which are not reinvested (as defined in the Senior Note Agreements), we may be required to prepay all or a portion of the Senior Notes. The obligations under the Senior Notes may be accelerated upon the occurrence of an event of default under the applicable Senior Note Agreement, each of which includes customary events of default including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974 and the failure to pay specified indebtedness. In June 2014, we paid off the remaining outstanding principal balance on the mortgage related to our worldwide headquarters in Westbrook, Maine.

At September 30, 2014 and December 31, 2013, we had $375.0 million and $277.0 million, respectively, outstanding under the Credit Facility with a weighted average effective interest rate of 1.6%. The funds available under the Credit Facility at September 30, 2014 and December 31, 2013 reflect a further reduction due to the issuance of a letter of credit for $1.0 million, which was issued in connection with our workers’ compensation policy.

Applicable interest rates on borrowings under the Credit Facility generally range from 0.875 to 1.375 percentage points (“Credit Spread”) above the London interbank offered rate or the Canadian Dollar-denominated bankers’ acceptance rate, based on our leverage ratio, or the prevailing prime rate plus a maximum spread of up to 0.375%, based on our leverage ratio.

Under the Credit Facility, we pay quarterly commitment fees of 0.15% to 0.35%, based on our leverage ratio, on any unused commitment.

The obligations under the Credit Facility may be accelerated upon the occurrence of an event of default under the Credit Facility, which includes customary events of default, including payment defaults, defaults in the performance of the affirmative, negative and financial covenants, the inaccuracy of representations or warranties, bankruptcy and insolvency related defaults, defaults relating to judgments, certain events related to employee pension benefit plans under the Employee Retirement Income Security Act of 1974, the failure to pay specified indebtedness and a change of control default.

At September 30, 2014, we were in compliance with the covenants of the Credit Facility.

In December 2013, we issued and sold through a private placement an aggregate principal amount of $150 million of senior notes consisting of $75 million of 3.94% Series A Senior Notes due December 11, 2023 (the “2023 Notes”) and $75 million of 4.04% Series B Senior Notes due December 11, 2025 (the “2025 Notes” and together with the 2023 Notes, the “December Notes”) under a Note Purchase Agreement among the Company, New York Life Insurance Company and the accredited institutional purchasers named therein (the “December 2013 Note Agreement”).

In July 2014, we issued and sold through a private placement an aggregate principal amount of $125 million of senior notes consisting of $75 million of 3.76% Series B Senior Notes due July 21, 2024 (the “2024 Notes”) and $50 million of 3.32% Series A Senior Notes due July 21, 2021 (the “2021 Notes” and together with the 2024 Notes, the “Prudential Notes”) under a Note Purchase and Private Shelf Agreement among the Company, Prudential Investment Management, Inc. and the accredited institutional purchasers named therein (the “July 2014 Note Agreement”).

In September 2014, we issued and sold through a private placement an aggregate principal amount of $75 million of 3.72% Senior Notes due September 4, 2026 (the “2026 Notes” and together with the Prudential Notes and the December Notes, the “Senior Notes”) under a Note Purchase Agreement dated as of July 22, 2014 among the Company, New York Life Insurance Company and the accredited institutional purchasers named therein (such agreement, together with July 2014 Note Agreement and December 2013 Note Agreement, the “Senior Note Agreements”).

The Senior Note Agreements contain affirmative, negative and financial covenants customary for agreements of this type. The negative covenants include restrictions on liens, indebtedness of our subsidiaries, priority indebtedness, fundamental changes, investments, transactions with affiliates, certain restrictive agreements and violations of laws and regulations.
