we continuously monitor our market share in the 18 to 33 foot sterndrive category as one indicator of the success of our strategies and the market 's acceptance of our products . for the nine months ended september 30 , 2016 ( latest data available to us ) , chaparral 's market share in the 18 to 33 foot sterndrive category was 14.7 percent compared to 13.9 percent during the same period in 2015 ; the highest market share in this category . chaparral 's market share in the 18 to 20 foot category was 10.1 percent during this period in 2016 , and its market share in the 21 to 33 foot category was 17.4 percent . chaparral 's market share concentrations within these size ranges has remained relatively consistent during the past several years . for the nine months ended september 30 , 2016 , robalo 's share of the 16 to 30 foot outboard sport fishing boat market was 4.6 percent . for the same period , chaparral 's share of the 20 to 24 foot jet boat market was approximately 8.9 percent . we will continue to monitor our market share and believe it to be important , but we believe that maximizing profitability takes precedence over growing our market share . furthermore , as we continue to expand the breadth of our product offerings within our core category and new categories , we consider our overall market share across the various powerboat categories to be of greater importance to the long-term health of our company than our market share within any specific type of recreational boat . 20 outlook we believe that recreational boating retail demand in many segments of the industry is improving . attendance and sales during the 2017 winter boat shows have been moderately higher than the 2016 winter boat show season , residential real estate markets have improved , consumer confidence has stabilized , and fuel prices have declined . we also believe that there is improved demand from consumers who have delayed purchasing a boat over the past few years due to economic uncertainty . although industry wide retail boat sales remain lower than they were prior to the 2008 financial crisis , retail boat sales have increased each year since 2011. we believe that continued improvements in retail boat sales will be modest due to the lack of strong economic improvement , which tends to discourage consumers from purchasing large discretionary goods such as pleasure boats . fluctuations in fuel prices can impact our sales , and during 2015 and 2016 fuel prices decreased significantly , and have declined to some of the lowest inflation-adjusted levels recorded during the past 10 years . in general , however , the overall cost of boat ownership has increased , especially in the sterndrive recreational boat market segment , which comprises approximately 42 percent of the company 's sales . the higher cost of boat ownership discourages consumers from purchasing recreational boats . for a number of years , marine products as well as other boat manufacturers have been improving their customer service capabilities , marketing strategies and sales promotions in order to attract more consumers to recreational boating as well as improve consumers ' boating experiences . the company provides financial incentives to its dealers for receiving favorable customer satisfaction surveys . in addition , the recreational boating industry conducts a promotional program which involves advertising and consumer targeting efforts , as well as other activities designed to increase the potential consumer market for pleasure boats . many manufacturers , including marine products , participate in this program . management believes that these efforts have incrementally benefited the industry and marine products . as in past years , marine products enhanced its selection of models for the 2017 model year which began on july 1 , 2016. we continue to emphasize the value-priced chaparral and robalo models , as well as the surf series , a new line of chaparral models first introduced for the 2017 model year . in addition , we continue to experience a favorable consumer reception to our chaparral vortex jet boats and chaparral suncoast outboard boats . we believe that these boat models will expand our customer base , and leverage our strong dealer network and reputation for quality and styling . during 2016 we also expanded our nationally advertised fixed retail pricing to include more of our models . we plan to continue to develop and produce additional new products for subsequent model years . our financial results for 2017 will depend on a number of factors , including interest rates , consumer confidence , the availability of credit to our dealers and consumers , fuel costs , the continued acceptance of our new products in the recreational boating market , our ability to compete in the competitive pleasure boating industry , and the costs of labor and certain of our raw materials and key components . 21 results of operations replace_table_token_4_th year ended december 31 , 2016 compared to year ended december 31 , 2015 net sales . marine products ' net sales increased by $ 34.3 million or 16.6 percent in 2016 compared to 2015. the increase was primarily due to a 17.8 percent increase in the number of boats sold , as well as an increase in parts and accessories sales , partially offset by a 3.0 percent decrease in the average gross selling price per boat . unit sales increased due to higher sales of our robalo outboard sport fishing boats , as well as increased unit sales of our chaparral h20 models and suncoast outboards . average selling prices decreased primarily due to a model mix which included higher sales of our value priced h2o models . domestic net sales were $ 220.1 million , an increase of 19.2 percent compared to the prior year . story_separator_special_tag income taxes - the effective income tax rate was 28.5 percent in 2016 , 31.8 percent in 2015 , and 28.8 percent in 2014. the effective tax rates vary due to changes in estimates of future taxable income , fluctuations in the tax jurisdictions in which the earnings and deductions are realized , variations in the relationship of tax-exempt income or losses to income before taxes and favorable or unfavorable adjustments to estimated tax liabilities related to proposed or probable assessments . as a result , the effective tax rate may fluctuate significantly on a quarterly or annual basis . the company establishes a valuation allowance against the carrying value of deferred tax assets when it is determined that it is more likely than not that the asset will not be realized through future taxable income . such amounts are charged to earnings in the period the determination is made . likewise , if it is later determined that it is more likely than not that the net deferred tax assets would be realized , the applicable portion of the previously provided valuation allowance is reversed . the company considers future market growth , forecasted earnings , future taxable income , the mix of earnings in the jurisdictions in which the company operates , and prudent and feasible tax planning strategies in determining the need for a valuation allowance . the company calculates the current and deferred tax provision based on estimates and assumptions that could differ from the actual results reflected in income tax returns filed during the subsequent year . adjustments based on filed tax returns are recorded when identified , which is generally in the third quarter of the subsequent year for u.s. federal and state provisions . deferred tax liabilities and assets are determined based on the differences between the financial and tax bases of assets and liabilities using enacted tax rates in effect in the year the differences are expected to reverse . 26 the amount of income taxes the company pays is subject to ongoing audits by federal and state tax authorities , which often result in proposed assessments . our estimate for the potential outcome for any uncertain tax issue is highly judgmental . the company believes it has adequately provided for any reasonably foreseeable outcome related to these matters . however , future results may include favorable or unfavorable adjustments to estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire . additionally , the jurisdictions in which earnings or deductions are realized may differ from current estimates . impact of recent accounting

pronouncements : · accounting standards update ( asu ) no . 2015-16 , business combinations ( topic 805 ) : simplifying the accounting for measurement-period adjustments . the amendments eliminate the
