2. Summary of Significant Accounting Policies and New Accounting Standards

Our significant accounting policies are described in the notes to the consolidated financial statements included in our Annual Report. As of December 31, 2016, there have been no material changes to any of the significant accounting policies contained therein, except for the application of Accounting Standards Update (“ASU”) 2015-03, Interest—Imputation of Interest (Subtopic 835-30), as of July 1, 2016. Prior periods have been adjusted to reflect the retrospective application of this guidance. For further discussion, see “—New Accounting Standards.”

Revisions of Previously Issued Financial Statements

During the three months ended June 30, 2016, the Company determined that amortization expense related to product-related intangible assets should be recorded in cost of goods sold rather than in selling, general and administrative expense within the consolidated statement of operations. The Company has revised its prior period financial statements, to correct the classification of amortization expense to increase cost of goods sold and reduce gross profit and selling, general and administrative expenses by $954 and $1,907 for the three and six months ended December 31, 2015, respectively. These revisions had no impact on the Company’s previously reported net income (loss) or cash flows. The Company evaluated the impact of the revisions on prior periods, assessing materiality quantitatively and qualitatively, and concluded the errors were not material to any previously issued financial statements.

Net Income per Share and Weighted Average Shares

Basic net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period.

Diluted net income per share is calculated by dividing net income by the weighted average number of common shares outstanding during the reporting period after giving effect to potential dilutive common shares equivalents resulting from the assumed exercise of stock options. For the three and six months ended December 31, 2016 and 2015, all common share equivalents were included in the calculation of diluted net income per share.

Dividends

We declared and paid quarterly cash dividends of $0.10 per share, totaling $3,941 and $7,882, during the three and six months ended December 31, 2016, respectively, to holders of our Class A common stock and Class B common stock.

New Accounting Standards

Financial Accounting Standards Board (“FASB”) ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, supersedes the current guidance by establishing a one-step goodwill impairment test. This new guidance requires an entity to compare the fair value of a reporting unit to its carrying amount, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. This ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early application is permitted for goodwill impairment tests performed after January 1, 2017. We will apply this guidance when performing our next goodwill impairment test. We do not expect adoption of this guidance to have a material effect on our consolidated financial statements. ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, provides specific guidance for the classification of certain transactions within the statement of cash flows. The issues addressed by this guidance include, but are not limited to, debt prepayments or debt extinguishment costs, contingent consideration payments made after a business combination and proceeds from the settlement of insurance claims. This ASU is effective for annual reporting periods beginning after December 15, 2017. Early application is permitted, as long as all provisions under the guidance are applied simultaneously. The provisions of this guidance are to be applied using a retrospective transition approach. We do not expect adoption of this guidance to have a material effect on our consolidated financial statements.

ASU 2016-02, Leases (Topic 842), supersedes the current lease accounting guidance and requires an entity to recognize assets and liabilities for both financing and operating leases on the balance sheet and requires additional qualitative and quantitative disclosures regarding leasing arrangements. This ASU is effective for annual reporting periods beginning after December 15, 2018. We are evaluating the impact of adoption of this guidance on our consolidated financial statements.

ASU 2015-11, Inventory (Topic 330), requires entities to measure inventory at the lower of cost and net realizable value (“NRV”). NRV is defined as “the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation.” The guidance is effective for annual periods beginning after December 15, 2016, and interim periods within those years. We do not expect adoption of this guidance to have a material effect on our consolidated financial statements.

ASU 2015-05, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) provides guidance regarding the treatment of cloud computing arrangements and if an arrangement includes a software license. We adopted this guidance during the three months ended September 30, 2016, and it had no material impact on our consolidated financial statements.

ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30), requires debt issuance costs to be presented as a reduction of the related liability. These costs were previously included in other assets. Debt issuance costs associated with line-of-credit arrangements may continue to be recognized in other assets. We adopted this guidance during the three months ended September 30, 2016, and applied the guidance retrospectively. Debt issuance costs of $2,538 as of June 30, 2016, have been presented as a reduction in long-term debt on our consolidated balance sheets.

ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), requires management to assess an entity’s ability to continue as a going concern within one year after the issuance date of the financial statements, and to provide related footnote disclosures in certain circumstances. Management will need to consider relevant conditions that are known and reasonably knowable at the issuance date. Substantial doubt exists if it is probable that the entity will be unable to meet its obligations within one year after the issuance date. Under the new standard, the definition of substantial doubt incorporates a likelihood threshold of “probable” similar to the current use of that term in GAAP for loss contingencies. ASU 2014-15 will be effective for annual periods ending after December 15, 2016, and for annual periods and interim periods thereafter. We do not expect adoption of this guidance to have a material effect on our consolidated financial statements.

ASU 2014-09, Revenue from Contracts with Customers (Topic 606), establishes principles for the recognition of revenue from contracts with customers. The underlying principle is to identify the performance obligations of a contract, allocate the revenue to each performance obligation and then to recognize revenue when the company satisfies a specific performance obligation of the contract. ASU 2015-14, Deferral of the Effective Date, amended ASU 2014-09, resulting in a one-year deferral of the effective date. ASU 2016-08, Principal versus Agent Considerations; ASU 2016-10, Identifying Performance Obligations and Licensing; and ASU 2016-12, Narrow-Scope Improvements and Practical Expedients also amended ASU 2014-09. The amendments are effective concurrent with the effective date for ASU 2014-09 for annual periods beginning after December 15, 2017, and interim periods within those years. We are evaluating the impact of adoption of this guidance on our consolidated financial statements.
