Net Income per Share The Company calculates net income per share using the two-class The Class A Common Stock has no voting rights, except (1) as required by law, (2) for the election of Class A Directors, and (3) that the approval of the holders of the Class A Common Stock is required for (a) certain future authorizations or issuances of additional securities which have rights senior to Class A Common Stock, (b) certain alterations of rights or terms of the Class A or Class B Common Stock as set forth in the Articles of Organization of the Company, (c) other amendments of the Articles of Organization of the Company, (d) certain mergers or consolidations with, or acquisitions of, other entities, and (e) sales or dispositions of any significant portion of the Company’s assets. The Class B Common Stock has full voting rights, including the right to (1) elect a majority of the members of the Company’s Board of Directors and (2) approve all (a) amendments to the Company’s Articles of Organization, (b) mergers or consolidations with, or acquisitions of, other entities, (c) sales or dispositions of any significant portion of the Company’s assets, and (d) equity-based and other executive compensation and other significant corporate matters. The Company’s Class B Common Stock is not listed for trading. Each share of the Class B Common Stock is freely convertible into one share of Class A Common Stock, upon request of any Class B holder, and participates equally in dividends. The Company’s unvested share-based payment awards include unvested shares (1) issued under the Company’s investment share program, which permits employees who have been with the Company for at least one year to purchase shares of Class A Common Stock and to purchase those shares at a discount ranging from 20% to 40% below market value based on years of employment starting after two years of employment, and (2) awarded as restricted stock awards at the discretion of the Company’s Board of Directors. The investment shares and restricted stock awards generally vest over five years in equal number of shares. The unvested shares participate equally in dividends. See Note I for a discussion of the current year unvested stock awards and issuances. Included in the computation of net income per diluted common share are dilutive outstanding stock options that are vested or expected to vest. At its discretion, the Board of Directors grants stock options to senior management and certain key employees. The terms of the employee stock options are determined by the Board of Directors at the time of grant. To date, stock options granted to employees vest over various service periods and/or based on the attainment of certain performance criteria and generally expire after ten years.

The vesting of these shares requires annual depletions, or sales by distributors to retailers, of certain of the Company’s brands to attain various thresholds during the period from 2017 to 2023. The remaining 5,000 shares were granted in 2017 to executive officers and the vesting of these shares requires annual depletions to attain certain thresholds in 2019. Furthermore, performance-based stock options to purchase approximately 5,000 shares of Class A Common Stock were not included in computing diluted income per share because the performance criteria of these stock options were not met and the options were cancelled during the twenty-six

Commitments and Contingencies	E. Commitments and Contingencies Contract Obligations The Company had outstanding total non-cancelable The Company has entered into contracts for the supply of a portion of its hops requirements. These purchase contracts extend through crop year 2022 and specify both the quantities and prices, denominated in U.S. Dollars, Euros and New Zealand Dollars, to which the Company is committed. Hops purchase commitments outstanding at July 1, 2017 totaled $42.4 million, based on the exchange rates on that date. The Company does not use forward currency exchange contracts and intends to purchase future hops using the exchange rate at the time of purchase. Currently, the Company has entered into contracts for barley and wheat with two major suppliers. The contracts include crop year 2016 and 2017 and cover the Company’s barley, wheat, and malt requirements for 2017 and part of 2018. These purchase commitments outstanding at July 1, 2017 totaled $16.3 million. The Company sources some of its glass bottles needs pursuant to a Glass Bottle Supply Agreement with Anchor Glass Container Corporation (“Anchor”), under which Anchor is the supplier of certain glass bottles for the Company’s Cincinnati Brewery and its Pennsylvania Brewery. This agreement also establishes the terms on which Anchor may supply glass bottles to other breweries where the Company brews its beers. Under the agreement with Anchor, the Company has minimum purchase commitments that are based on Company-provided production estimates which, under normal business conditions, are expected to be fulfilled. Minimum purchase commitments under the agreement, assuming the supplier is unable to replace lost production capacity cancelled by the Company, as of July 1, 2017 totaled $7.7 million. The Company has various operating lease agreements for facilities and equipment as of July 1, 2017. Terms of these leases include, in some instances, scheduled rent increases, renewals, purchase options and maintenance costs, and vary by lease. These lease obligations expire at various dates through 2022. The contractual obligation on these lease agreements as of July 1, 2017 totaled $14.3 million. Currently, the Company brews and packages more than 90% of its volume at Company-owned breweries. In the normal course of its business, the Company has historically entered into various production arrangements with other brewing companies. Pursuant to these arrangements, the Company purchases the liquid produced by those brewing companies, including the raw materials that are used in the liquid, at the time such liquid goes into fermentation. The Company is required to repurchase all unused raw materials purchased by the brewing company specifically for the Company’s beers at the brewing company’s cost upon termination of the production arrangement. The Company is also obligated to meet annual volume requirements in conjunction with certain production arrangements. These requirements are not material to the Company’s operations. Litigation The Company is not a party to any pending or threatened litigation, the outcome of which would be expected to have a material adverse effect upon its financial condition or the results of its operations. In general, while the Company believes it conducts its business appropriately in accordance with laws, regulations and industry guidelines, claims, whether or not meritorious, could be asserted against the Company that might adversely impact the Company’s results.

Fair Value Measures

Fair Value Measures	6 Months Ended
	Jul. 01, 2017
Fair Value Measures	H. Fair Value Measures The Company defines fair value as the price that would be received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels and bases the categorization within the hierarchy upon the lowest level of input that is available and significant to the fair value measurement. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). • Level 1 — Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 — Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. If the asset or liability has a specified (contractual) term, a Level 2 input must be observable for substantially the full term of the asset or liability. • Level 3 — Level 3 inputs are unobservable inputs for the asset or liability in which there is little, if any, market activity for the asset or liability at the measurement date. All financial assets or liabilities that are measured at fair value on a recurring basis (at least annually) have been segregated into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date. The assets or liabilities measured at fair value on a recurring basis are summarized in the table below (in thousands): As of July 1, 2017 Level 1 Level 2 Level 3 Total Cash equivalents $ 70,762 $ — $ — $ 70,762 As of December 31, 2016 Level 1 Level 2 Level 3 Total Cash equivalents $ 89,966 $ — $ — $ 89,966 The Company’s cash equivalents listed above represent money market funds and are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The money market funds were invested substantially in United States Treasury and government securities. The Company does not adjust the quoted market price for such financial instruments. Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents held in money market funds. At July 1, 2017 and December 31, 2016, the Company had money market funds which have been deemed “Triple A” rated. The Company considers the “Triple A” rated money market funds to be a large, highly-rated investment-grade institution. As of July 1, 2017 and December 31, 2016, the Company’s cash and cash equivalents balance was $71.7 million and $91.0 million, respectively, including money market funds amounting to $70.8 million and $90.0 million, respectively. Cash, certificates of deposit, receivables and payables are carried at their cost, which approximates fair value, because of their short-term nature. Financial instruments not recorded at fair value in the consolidated financial statements are summarized in the table below (in thousands): As of July 1, 2017 Level 1 Level 2 Level 3 Total Note payable $ — $ 340 $ — $ 340 As of December 31, 2016 Level 1 Level 2 Level 3 Total Note payable $ — $ 400 $ — $ 400
