Accounting Changes And Error Corrections [Abstract]
New Accounting Pronouncements	3. NEW ACCOUNTING PRONOUNCEMENTS: In May 2014, the FASB issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (ASU 2014-9), a converged standard on revenue recognition. The new pronouncement requires revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also specifies the accounting for some costs to obtain or fulfill a contract with a customer, as well as enhanced disclosure requirements. ASU 2014-9 is effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Early adoption is permitted for annual reporting periods beginning after December 15, 2016. While we are continuing to evaluate the impact the adoption of ASU 2014-09 will have on our consolidated financial statements, we currently do not believe the adoption of this standard will have a material impact on our consolidated financial statements, or will cause a significant change to our current accounting policies or internal controls over financial reporting for revenue recognition on boat, motor, and trailer sales, parts and service operations, brokerage commissions, slip and storage services, charter rentals, and fee income generated from F&I products. In July 2015, the FASB issued ASU No. 2015-11, “Inventory (Topic 330).” The pronouncement was issued to simplify the measurement of inventory and changes the measurement from lower of cost or market to lower of cost and net realizable value. This pronouncement is effective for reporting periods beginning after December 15, 2016. The adoption of ASU 2015-11 is not expected to have a significant impact on the Company’s consolidated financial position or results of operations. In November 2015, FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, which eliminates the current requirement to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, entities will be required to classify all deferred tax assets and liabilities as noncurrent. This ASU is effective for annual periods beginning after fiscal December 15, 2017 and early adoption is permitted as of the beginning of an interim or annual reporting period. We retrospectively adopted ASU 2015-17 as of June 30, 2016, and as a result have reported deferred tax assets and liabilities as noncurrent on the balance sheet for all periods presented. This early adoption resulted in approximately $9.3 million in deferred tax assets previously reported as current assets in the consolidated balance sheet as of September 30, 2015 being recorded as noncurrent assets as of September 30, 2015. Because the application of this guidance affects classification only, such reclassifications did not have a material effect on the Company’s consolidated financial position or results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (ASU 2016-02). This update requires organizations to recognize lease assets and lease liabilities on the balance sheet and also disclose key information about leasing arrangements. This ASU is effective for annual reporting periods beginning on or after December 15, 2018, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual period. While we are continuing to evaluate the impact of the adoption of ASU 2016-02 on our consolidated financial statements, we believe the adoption of ASU 2016-02 may have a significant and material impact to our consolidated balance sheet given our current lease agreements for our leased retail locations. We are currently evaluating the impact the adoption of this ASU will have on our other consolidated financial statements. Based on a preliminary assessment, we expect that most of our operating lease commitments will be subject to the new guidance and recognized as operating lease liabilities and right-of-use assets upon adoption, resulting in a material increase in the assets and liabilities recorded on our consolidated balance sheet. We are continuing our assessment, which may identify additional impacts this standard will have on our consolidated financial statements and related disclosures and internal controls over financial reporting. In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718), (ASU 2016-09).” This update was issued as part of the FASB’s simplification initiative and affects all entities that issue share-based payment awards to their employees. The amendments in this update cover such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. This update is effective for annual and interim periods beginning after December 15, 2016. We elected to early adopt the new guidance in the fourth quarter of fiscal year 2016 which requires us to reflect any adjustments as of October 1, 2015, the beginning of the annual period that includes the interim period of adoption. The primary effect of adoption was the recognition of excess tax benefits in our provision for income taxes rather than paid-in capital for all periods in fiscal year 2016. This early adoption resulted in an approximately $5.2 million increase in deferred tax assets and retained earnings as of October 1, 2015, the beginning of fiscal year 2016. The recognition of excess tax benefits in our provision for income taxes rather than paid-in capital resulted in an income tax benefit of $633,000 for the three months ended September 30, 2016. Additionally, the adoption in the fourth quarter of fiscal year 2016 of ASU 2016-09 resulted in additional income tax expense of $201,000 for the three months ended December 31, 2015, an income tax benefit of $67,000 for the three months ended March 31, 2016, and an additional income tax expense of $242,000 for the three months ended June 30, 2016, from the previously reported income tax provisions in the condensed consolidated statements of operations for the first, second, and third quarter, respectively, during fiscal year 2016. Lastly, the adoption of ASU 2016-09 resulted in $541,000 for payments for tax withholdings for equity awards previously recorded in operating activities on the consolidated statements of cash flows for fiscal year 2015 now being recorded in financing activities for fiscal year 2015.
