Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Pursuant to U.S. GAAP, accruals for estimated losses are recorded at the time information becomes available indicating that losses are probable and that the amounts are reasonably estimable. As is the case with other companies in similar industries, the Company faces exposure from actual or potential claims and legal proceedings from a variety of sources. Some of these exposures, as discussed below, have the potential to be material. Environmental Matters The Company is subject to a variety of environmental and pollution control laws and regulations in all jurisdictions in which it operates. Fox River Settlement and Remaining Claim In March 2014, U.S. Paper Mills Corp. (U.S. Mills), a wholly owned subsidiary of the Company, and five other defendants reached a potential settlement with the United States Environmental Protection Agency (EPA) and the Wisconsin Department of Natural Resources (WDNR) for natural resource damages and the environmental cleanup of the lower Fox River in Wisconsin. The settlement was approved by the court on February 6, 2015 and became final on April 7, 2015 when the time for appeal of the court's order expired with no appeal having been taken. The terms of the settlement required U.S. Mills to pay $14,700, which was paid in April 2014, and protect U.S. Mills from claims by other parties relating to natural resource damages and the cleanup of the lower Fox River, except claims pursuant to Section 107 of the Comprehensive Environment Response, Compensation and Liability Act (CERCLA). The finalization of the settlement leaves intact a claim by Appvion, Inc., under Section 107 of CERCLA against eight defendants, including U.S. Mills, to recover response costs allegedly incurred by Appvion consistent with the national contingency plan for responding to release or threatened release of hazardous substances into the lower Fox River. The claim is asserted for approximately $200,000. Although the Company believes that the maximum amount for which the defendants could be liable is substantially less, the court has not yet ruled on the issue. At December 31, 2014, U.S. Mills had reserves totaling $37,775 for potential liabilities associated with the lower Fox River. During the quarter ending March 29, 2015, U.S. Mills spent a total of $232 on legal fees related to Fox River. As a result of the settlement becoming final, the Company reversed $32,543 of the reserves, leaving a total of $5,000 reserved at March 29, 2015 for remaining potential liabilities associated with the lower Fox River. The reversal of these reserves resulted in reductions of "Selling, general and administrative expenses" and "Accrued expenses and other" in the Company's Condensed Consolidated Financial Statements in the first quarter of 2015. Through June 28, 2015, the Company has spent approximately $488 on legal costs related to the remaining Appvion claim, leaving a reserve of $4,512 remaining at June 28, 2015. The actual costs that may be incurred associated with the Appvion claim are dependent upon many factors and it is possible that costs could ultimately be higher than the amount provided for in the remaining reserve. Because of the continuing uncertainties surrounding U.S. Mills' possible liability, including a potentially favorable resolution, the Company cannot currently estimate its potential liability, damages or range of potential loss, if any, beyond the amounts reserved, and an adverse resolution of these matters could have an adverse effect on the Company's financial position, results of operations and/or cash flows. The Company believes that the maximum additional exposure to its consolidated financial position beyond the amount reserved at June 28, 2015 is limited to the equity position of U.S. Mills, which was approximately $123,000 at June 28, 2015. Tegrant On November 8, 2011, the Company completed the acquisition of Tegrant. During its due diligence, the Company identified several potential environmentally contaminated sites. The total remediation cost of these sites was estimated to be $18,850 at the time of acquisition and an accrual in this amount was recorded on Tegrant’s opening balance sheet. Since the acquisition, the Company has spent a total of $649 on remediation of these sites. During 2014, the Company increased its reserves for these sites by $324 in order to reflect its best estimate of what it is likely to pay in order to complete the remediation. At June 28, 2015 and December 31, 2014, the Company's accrual for Tegrant's environmental contingencies totaled $18,525 and $18,635, respectively. The Company cannot currently estimate its potential liability, damages or range of potential loss, if any, beyond the amounts accrued with respect to this exposure. However, the Company does not believe that the resolution of this matter has a reasonable possibility of having a material adverse effect on the Company's financial statements. Village of Rockton On September 15, 2014, the Village of Rockton, Illinois instituted 81 actions against the Company in the Circuit Court for the Seventeenth Judicial Circuit, Winnebago, Illinois. Each action seeks to assess penalties of up to $0.75 per day since December 2, 2007 for violations of one of three sections of the Municipal Code that: (a) require lots or premises to be maintained in a safe and sanitary condition at all times; (b) make it unlawful for any substance which shall be dangerous or detrimental to health to be allowed to exist in connection with any business, be used therein or used in any work or labor carried on in the Village and prohibit any health menace be permitted to exist in connection with business or in connection with any such work or labor; and (c) make it unlawful for any ashes, rubbish, tin cans and all combustibles to be deposited or dumped upon any lot or land in the Village, and require that they be deposited or dumped in the area set aside for that purpose. The actions relate to a paper plant in the Village closed by the Company in 2008 that the Company is in the process of remediating through the Illinois Environmental Protection Agency’s “brownfields” program. The Company has removed the cases to the United States District Court for the Northern District of Illinois and plans to vigorously defend its interests while continuing to participate in the “brownfields” program. The Company cannot currently estimate its potential liability, damages or range of potential loss, if any, with respect to this exposure. Other environmental matters The Company has been named as a potentially responsible party at several other environmentally contaminated sites. All of the sites are also the responsibility of other parties. The potential remediation liabilities are shared with such other parties, and, in most cases, the Company’s share, if any, cannot be reasonably estimated at the current time. However, the Company does not believe that the resolution of these matters has a reasonable possibility of having a material adverse effect on the Company's financial statements. Summary As of June 28, 2015 and December 31, 2014, the Company (and its subsidiaries) had accrued $25,770 and $59,253, respectively, related to environmental contingencies. These accruals are included in “Accrued expenses and other” on the Company’s Condensed Consolidated Balance Sheets. Other Legal Matters In addition to those matters described above, the Company is subject to other various legal proceedings, claims, and litigation arising in the ordinary course of business. While the outcome of these matters could differ from management’s expectations, the Company does not believe the resolution of these matters has a reasonable possibility of having a material adverse effect on the Company’s financial statements.
