Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies	Commitments and Contingencies Legal Matters From time to time in the ordinary course of its business, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to intellectual property, contract, product liability, employment, and environmental matters. In accordance with accounting standards regarding loss contingencies, the Company accrues an undiscounted liability for those contingencies where the incurrence of a loss is probable and the amount can be reasonably estimated, and the Company discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for its financial statements not to be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. Because litigation outcomes are inherently unpredictable, the Company’s evaluation of legal proceedings often involves a series of complex assessments by management about future events and can rely heavily on estimates and assumptions. While the consequences of certain unresolved proceedings are not presently determinable, and an estimate of the probable and reasonably possible loss or range of loss in excess of amounts accrued for such proceedings cannot be reasonably made, an adverse outcome from such proceedings could have a material adverse effect on the Company’s earnings in any given reporting period. However, in the opinion of management, after consulting with legal counsel, and taking into account insurance coverage, any ultimate liability related to current outstanding claims and lawsuits, individually or in the aggregate, is not expected to have a material adverse effect on the Company’s consolidated financial statements, as a whole. The Company’s currently pending legal matters of note are discussed below: Environmental Matters. In 2001, the Company was notified by the California Department of Toxic Substances Control (“State”) that it may have liability associated with the clean-up of the one-third acre Davis Chemical Company site in Los Angeles, California. The Company has been included in the clean-up program because it was one of the companies that used the Davis Chemical Company site for waste recycling and/or disposal between 1949 and 1990. The Company joined with other potentially responsible parties and entered into a Consent Order with the State that required the group to perform a soils investigation at the site and submit a remediation plan. The State has approved the remediation plan, which completes the group’s obligations under the Consent Order. Although the Consent Order does not require the group to remediate the site and the State has indicated it intends to look to other parties for remediation, the State has not yet issued “no further action” letters to the group members. To date, the Company’s share of the group’s expenses has not been material and has been expensed as incurred. The Company has used an environmental firm, specializing in hydrogeology, to perform monitoring of the groundwater at the Company’s former facility in Newbury Park, California that was leased for approximately forty years. The Company vacated the building in May 2002. Certain contaminants have been found in the local groundwater and site soils. Groundwater monitoring results to date over a number of years indicate that the majority of groundwater contaminants are believed to come, in full or in material part, from adjacent facilities. Responsibility for soil contamination remains under investigation. The location of key soil contamination (and some related groundwater impact) is concentrated in an area of an underground storage tank that the Company believes to have been installed and used in the early 1960s by a former tenant at the site who preceded the Company’s tenancy. There are no claims pending with respect to environmental matters at the Newbury Park site. The applicable regulatory agency having authority over the site issued joint instructions in November 2008, ordering the Company and the current owner of the site to perform additional assessments and surveys, and to create ongoing groundwater monitoring plans before any final regulatory action for “no further action” may be approved. In September 2009, the regulatory agency issued supplemental instructions to the Company and the current site owner regarding previously ordered site assessments, surveys and groundwater monitoring. In November 2012, the regulatory agency added two more potentially responsible parties to the matter, based on historical evidence of past occupancy or operations at the site dating to the 1960s. In addition, the regulatory agency’s November 2012 action included a draft cleanup and abatement order to all the parties. Responses to the draft orders were submitted in a timely manner by all the parties in January 2013. Further action and response from the regulatory agency is pending. The parties are expected to work cooperatively in responding to and determining the appropriate scope and extent of additional site investigative and categorization work, as well as in relation to any ultimate proposed clean up and abatement work. The Company has accrued liabilities where it is probable that a loss will be incurred and the cost or amount of loss can be reasonably estimated. Based upon, and in anticipation of the likely outcome associated with the November 2012 draft cleanup and abatement order, the Company engaged an environmental firm to assist in an assessment of this site consistent with the direction and scope of the draft cleanup and abatement order. Based on the Company’s preliminary assessment, it has determined a likely range of probable loss between $2.5 million and $5.7 million. Given the early nature of the draft clean up and abatement order and uncertainties associated with environmental assessment and the remediation activities, the Company is unable to determine a best estimate within the range of loss. Therefore, the Company recorded the minimum amount of $2.5 million under “Accrued liabilities” on the unaudited consolidated condensed balance sheets, and included in the consolidated condensed statement of income under “Selling, general and administrative” in the third quarter of fiscal year 2013. These estimates could change as a result of changes in planned remedial actions, further actions from the regulatory agency, remediation technology, and other factors. Commercial Disputes The Company periodically is involved in disputes arising in the normal course of business regarding products or services provided to the Company by vendors or service providers. Historically, the cost of commercial disputes has been immaterial to the Company’s consolidated financial statements. Indemnification The Company has entered into agreements with its current executive officers and directors indemnifying them against certain liabilities incurred in connection with the performance of their duties. The Company’s Certificate of Incorporation and Bylaws contain comparable indemnification obligations with respect to the Company’s current directors and employees. Product Warranties The Company’s general warranty policy provides for repair or replacement of defective parts. In some cases, a refund of the purchase price is offered. In certain instances the Company has agreed to other warranty terms, including some indemnification provisions. The product warranty accrual reflects the Company’s best estimate of probable liability under its product warranties. The Company accrues for known warranty issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical experience. Historically, warranty expense has been immaterial to the Company’s consolidated financial statements.

Legal Matters

From time to time in the ordinary course of its business, the Company is involved in various claims, litigation, and other legal actions that are normal to the nature of its business, including with respect to intellectual property, contract, product liability, employment, and environmental matters.
