based on the review of the weighted-average assumptions used to calculate the net periodic benefit cost what was the ratio of the expected long-term return on plan assets ( 1 ) to the discount rate used to determine service cost in 2017
Important information:
table_1: the discount rate used to determine service cost of 2018 is 1.3% ( 1.3 % ) ; the discount rate used to determine service cost of 2017 is 1.5% ( 1.5 % ) ; the discount rate used to determine service cost of 2016 is 1.6% ( 1.6 % ) ;
table_2: the discount rate used to determine interest cost of 2018 is 2.5% ( 2.5 % ) ; the discount rate used to determine interest cost of 2017 is 3.0% ( 3.0 % ) ; the discount rate used to determine interest cost of 2016 is 3.0% ( 3.0 % ) ;
table_4: the expected long-term return on plan assets ( 1 ) of 2018 is 4.8% ( 4.8 % ) ; the expected long-term return on plan assets ( 1 ) of 2017 is 5.0% ( 5.0 % ) ; the expected long-term return on plan assets ( 1 ) of 2016 is 5.1% ( 5.1 % ) ;

Please answer the following financial question based on the context provided. Make sure to give the answer in raw number, not in percentage and without any units. If the question asks for percentage the value should be less than 1
Context:
remaining service period of active members expected to receive benefits under the plan or , in the case of closed plans , the expected future lifetime of the employees participating in the plan . for the years ended december 31 , 2018 and 2017 , the service cost component of net periodic benefit cost was classified in selling , general and administrative expenses , while the other components of net periodic benefit cost were classified in other income , net in our consolidated statements of income . for the year ended december 31 , 2016 , all components of net periodic benefit expense were included in selling , general , and administrative expenses in our consolidated statements of income . for the year ending december 31 , 2019 , we expect net periodic benefit costs to increase by approximately $ 2 million due to the fact that we will incur a full year of pension expense related to our stahlgruber business , compared to a partial year in 2018 . the table below summarizes the weighted-average assumptions used to calculate the net periodic benefit cost in the table above: .
Table
                                               | 2018           | 2017           | 2016          
discount rate used to determine service cost   | 1.3% ( 1.3 % ) | 1.5% ( 1.5 % ) | 1.6% ( 1.6 % )
discount rate used to determine interest cost  | 2.5% ( 2.5 % ) | 3.0% ( 3.0 % ) | 3.0% ( 3.0 % )
rate of future compensation increase           | 1.9% ( 1.9 % ) | 1.3% ( 1.3 % ) | 2.0% ( 2.0 % )
expected long-term return on plan assets ( 1 ) | 4.8% ( 4.8 % ) | 5.0% ( 5.0 % ) | 5.1% ( 5.1 % )
expected long-term return on plan assets ( 1 ) 4.8% ( 4.8 % ) 5.0% ( 5.0 % ) 5.1% ( 5.1 % ) ( 1 ) our expected long-term return on plan assets is determined based on our asset allocation and estimate of future long- term returns by asset class . assumed mortality is also a key assumption in determining benefit obligations and net periodic benefit cost . in some of our european plans , a price inflation index is also an assumption in determining benefit obligations and net periodic benefit as of december 31 , 2018 , the pre-tax amounts recognized in accumulated other comprehensive income consisted of $ 10 million of net actuarial losses for our defined benefit plans that have not yet been recognized in net periodic benefit cost . of this amount , we expect $ 0.2 million to be recognized as a component of net periodic benefit cost during the year ending december 31 , 2019 . fair value of plan assets fair value is defined as the amount that would be received for selling an asset or paid to transfer a liability in an orderly transaction between market participants . the tiers in the fair value hierarchy include : level 1 , defined as observable inputs such as quoted market prices in active markets ; level 2 , defined as inputs other than quoted prices in active markets that are either directly or indirectly observable ; and level 3 , defined as significant unobservable inputs in which little or no market data exists , therefore requiring an entity to develop its own assumptions . investments that are valued using net asset value ( "nav" ) ( or its equivalent ) as a practical expedient are excluded from the fair value hierarchy disclosure . the following is a description of the valuation methodologies used for assets reported at fair value . the methodologies used at december 31 , 2018 and december 31 , 2017 are the same . level 1 investments : cash and cash equivalents are valued based on cost , which approximates fair value . mutual funds are valued based on reported market prices on the last trading day of the fiscal year . level 3 investments : investments in insurance contracts represent the cash surrender value of the insurance policy . these are actuarially determined amounts based on projections of future benefit payments , discount rates , and expected long- term rate of return on assets. .
