Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements We determine a fair value measurement based on the assumptions a market participant would use in pricing an asset or liability, in accordance with Accounting Standards Codification (“ASC”) 820 - Fair Value Measurement (“ASC 820”). The fair value measurement guidance established a three level hierarchy making a distinction between market participant assumptions based on (i) unadjusted quoted prices for identical assets or liabilities in an active market (Level 1), (ii) quoted prices in markets that are not active or inputs that are observable either directly or indirectly for substantially the full term of the asset or liability (Level 2), and (iii) prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement (Level 3). Fair value measurements for defined benefit pension plan The fair value hierarchy discussed above not only is applicable to assets and liabilities that are included in our consolidated balance sheets, but also is applied to certain other assets that indirectly impact our consolidated financial statements. For example, we sponsor and contribute to a single-employer defined benefit pension plan (see Note 9). Assets contributed by us become the property of the pension plan. Even though the Company no longer has control over these assets, we are indirectly impacted by subsequent fair value adjustments to these assets. The actual return on these assets impacts our future net periodic benefit cost, as well as amounts recognized in our consolidated balance sheets. The Company uses the fair value hierarchy to measure the fair value of assets held by our pension plan. We believe the pension plan asset fair value valuation to comprise both Level 1 and Level 2 in the fair value hierarchy. Level 1 assets held in the pension plan under GAAP consist of publicly traded securities, and Level 2 assets held in the pension plan under GAAP consist of collective investment trust assets. Fair value measurements for financial instruments Carrying amounts for our financial instruments are not significantly different from their fair value, with the exception of our mortgage. To determine the fair value of our mortgage, we used a discounted cash flow model. ASC 820 generally states that the fair value measurement of a liability contemplates the transfer of the liability to a market participant at the measurement date, and, therefore, the liability is assumed to continue (i.e., it is assumed to be neither settled nor extinguished), and the market participant to whom the liability is transferred would be required to fulfill the obligation. ASC 820 also implies that the liability is hypothetically transferred to a market participant of equal credit standing. The clarification that fair value is not based on the price to settle a liability with the existing counterparty, but rather to transfer it to a market participant of equal credit standing, requires that fair market value be established at the measurement date, regardless of subsequent settlement of the liability after the measurement date. The fair value of our debt is therefore not necessarily indicative of the amount at which we subsequently settled our debt. We believe the mortgage fair value valuation to be Level 2 in the fair value hierarchy, as the valuation model has inputs that are observable for substantially the full term of the liability. Assumptions critical to our fair value measurements in the period are present value factors used in determining fair value and an interest rate. At December 30, 2017, the discounted fair value of the mortgage was approximately $1.9 million more than the $97.9 million approximate carrying value of the mortgage.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.
