movements in the underlying plan asset value and projected benefit obligation ( pbo ) are dependent on actual return on investments as well as our assumptions in respect of the discount rate , annual member mortality rates , future return on assets and future inflation . a change in any one of these assumptions could impact the plan asset value , pbo and pension charge recognized in the income statement . such changes could adversely impact our results of operations and financial position . for example , a 0.25 % change in the discount rate assumption would change the pbo by approximately $ 29 million and the net pension credit for 2015 by approximately $ 0.3 million . a 0.25 % change in the level of price inflation assumption would change the pbo by approximately $ 22 million and the net pension credit for 2015 would not be significantly changed . further information is provided in note 9 of the notes to the consolidated financial statements . deferred tax and uncertain income tax positions at december 31 , 2014 , no valuation allowance is required against our foreign tax credit carry forwards within deferred tax as management believes that all the foreign tax credit carry forwards can be utilized in future periods prior to their expiration . 25 no deferred taxes have been provided for on the unremitted earnings of our overseas subsidiaries as any tax basis differences relating to investments in these overseas subsidiaries are considered to be permanent in duration . we have no current intention to repatriate past or future earnings of our overseas subsidiaries and consider that these earnings have been reinvested overseas . if circumstances were to change that would cause these earnings to be repatriated an additional u.s. tax liability could be incurred , and we continue to monitor this position . the calculation of our tax liabilities involves evaluating uncertainties in the application of complex tax regulations . we recognize liabilities for anticipated tax audit issues based on our estimate of whether , and the extent to which , additional taxes will be required . if we ultimately determine that payment of these amounts is unnecessary , we reverse the liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary . we also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained , based on technical merits , when challenged by the taxing authorities . to the extent that we prevail in matters for which liabilities have been established , or are required to pay amounts in excess of our liabilities , our effective tax rate in a given period may be materially affected . an unfavorable tax settlement may require cash payments and result in an increase in our effective tax rate in the year of resolution . a favorable tax settlement may be recognized as a reduction in our effective tax rate in the year of resolution . we report interest and penalties related to uncertain income tax positions as income taxes . for additional information regarding uncertain income tax positions see note 10 of the notes to the consolidated financial statements . business combinations the acquisition method of accounting requires that we recognize the assets acquired and liabilities assumed at their acquisition date fair values . goodwill is measured as the excess of consideration transferred over the acquisition date net fair values of the assets acquired and the liabilities assumed . the measurement of the fair values of assets acquired and liabilities assumed requires considerable judgment . although independent appraisals may be used to assist in the determination of the fair values of certain assets and liabilities , those determinations are usually based on significant estimates provided by management , such as forecast revenue or profit . in determining the fair value of intangible assets , an income approach is generally used and may incorporate the use of a discounted cash flow method . in applying the discounted cash flow method , the estimated future cash flows and residual values for each intangible asset are discounted to a present value using a discount rate appropriate to the business being acquired . these cash flow projections are based on management 's estimates of economic and market conditions including revenue growth rates , operating margins , capital expenditures and working capital requirements . 26 while we use our best estimates and assumptions as part of the process to value assets acquired and liabilities assumed at the acquisition date , our estimates are inherently uncertain and subject to refinement . during the measurement period , which occurs before finalization of the purchase price allocation , changes in assumptions and estimates that result in adjustments to the fair values of assets acquired and liabilities assumed will have a corresponding offset to goodwill . subsequent adjustments will impact our consolidated statements of income . goodwill the company 's reporting units , the level at which goodwill is tested for impairment , are consistent with the reportable segments . the components in each segment ( including products , markets and competitors ) have similar economic characteristics and the segments , therefore , reflect the lowest level at which operations and cash flows can be sufficiently distinguished , operationally and for financial reporting purposes , from the rest of the company . the company tests goodwill annually for impairment , or between years if events occur or circumstances change which suggest that an impairment may have occurred . the company performs its annual goodwill tests in respect of fuel specialties and performance chemicals as at december 31 each year . in reviewing for any impairment charge the fair values of the reporting segments are estimated using an after-tax cash flow methodology based on management 's best available estimates at that time . story_separator_special_tag octane additives net sales : decreased by 15 % with decreased volumes ( down 18 percentage points ) , due to the timing of shipments and declining demand from major customers , and an improved customer mix ( up 4 percentage points ) , together with reduced revenue from our environmental remediation business ( down 1 percentage points ) . in both 2013 and 2012 , sales were focused in the middle east and northern africa . gross margin : decreased by 1.6 percentage points from 48.7 % to 47.1 % , due to lower manufacturing volumes , partly offset by favorable customer mix and non-recurring freight storage costs in the prior year . operating expenses : decreased by $ 1.6 million from $ 7.9 million to $ 6.3 million , due to the efficient management of the cost base . other income statement captions pension credit/ ( charge ) : this non-cash charge increased to a $ 2.3 million net charge in 2013 compared to a $ 1.6 million net charge in 2012 , after revising the amortization of actuarial losses in 2012. the increase in the net charge in 2013 primarily relates to increased actuarial net losses being amortized to the income statement . corporate costs : the year on year increase of 13 % , or $ 5.0 million , reflected $ 8.3 million higher legal , compliance , professional and other expenses , including acquisition-related costs of $ 1.8 million in 2013 compared to $ 2.8 million in 2012 ; $ 1.8 million higher personnel-related compensation costs , primarily due to higher accruals for share based compensation expense , driven by the rise in our stock price compared to the same period in the prior year ; $ 0.7 million higher information technology service platform costs ; offset by a $ 5.8 million reduction in the charge for the long-term incentive plan which completed at the end of 2012. impairment of octane additives segment goodwill : was $ 1.3 million in 2013 and $ 1.2 million in 2012. other net income/ ( expense ) : other net income of $ 4.1 million primarily related to gains of $ 5.8 million on translation of net assets denominated in non-functional currencies in our european businesses , partly offset by net foreign exchange losses on foreign currency forward exchange contracts of $ 1.6 million . in 2012 , other net expense of $ 2.0 million primarily related to losses on translation of net assets denominated in non-functional currencies in our european businesses offset by net foreign exchange gains on foreign currency forward exchange contracts . 36 interest expense , net : increased to $ 1.9 million in 2013 from $ 1.2 million in 2012 due to the higher level of borrowing during 2013 , used primarily to fund our acquisition activity . income taxes : the effective tax rate was 16.2 % and 28.3 % in 2013 and 2012 , respectively . the effective tax rate , once adjusted for income tax provisions and for the tax impact of acquisition-related funding , was 15.9 % in 2013 compared with 20.2 % in 2012. the company believes that this adjusted effective tax rate , a non-gaap financial measure , provides useful information to investors and may assist them in evaluating the company 's underlying performance and identifying operating trends . in addition , management uses this non-gaap financial measure internally to evaluate the performance of the company 's operations and for planning and forecasting in subsequent periods . replace_table_token_17_th in addition to those mentioned above , the following factors had a significant impact on the company 's effective tax rate as compared to the u.s. federal income tax rate of 35 % : replace_table_token_18_th the impact on the effective tax rate from profits earned in foreign jurisdictions with lower tax rates varies as the geographical mix of the company 's profits changes year on year . in 2013 , the company 's income tax expense benefited to a lesser degree from a proportion of its overall profits arising in switzerland than in 2012. this resulted in a $ 9.3 million benefit in switzerland ( 2012  $ 12.0 million ) . in addition , there was a $ 3.9 million benefit in relation to the united kingdom ( 2012  $ 3.3 million ) and a $ 0.3 million benefit in relation to germany ( 2012  $ 0.7 million ) . foreign income inclusions arise each year from certain types of income earned overseas being taxable under u.s. tax regulations . these types of income include subpart f income , principally from foreign based company sales in the united kingdom , including the associated section 78 tax gross up , and also from the income earned by certain overseas subsidiaries 37 taxable under the u.s. tax regime . in 2013 , the amount of subpart f income and the associated section 78 gross up amounted to $ 4.3 million ( 2012  $ 4.3 million ) . the income earned by certain overseas subsidiaries taxable under the u.s. tax regime decreased to $ 1.2 million from $ 2.5 million in 2012. a dividend from an overseas subsidiary , remitted to the u.s. , increased foreign income inclusions by $ 39.0 million during 2012. in 2013 no dividends were remitted to the u.s .. foreign tax credits can fully or partially offset these incremental u.s. taxes from foreign income inclusions . the utilization of foreign tax credits varies year on year as this is dependent on a number of variable factors which are difficult to predict and may in certain years prevent any offset of foreign tax credits . in total , $ 4.2 million of foreign tax credits were utilized during 2013 to partially offset the incremental u.s. taxes arising from foreign income inclusions in the year ( 2012  an overseas dividend was remitted to the u.s. to provide funding for the company 's acquisition program and $

 Suspicious Activity Report : movements in the underlying plan asset value and projected benefit obligation ( pbo ) are dependent on actual return on investments as well as our assumptions in respect of the discount rate , annual member mortality rates , future return on assets and future inflation . a change in any one of these assumptions could impact the plan asset value , pbo and pension charge recognized in the income statement . such changes could adversely impact our results of operations and financial position . for example , a 0.25 % change in the discount rate assumption would change the pbo by approximately $ 29 million and the net pension credit for 2015 by approximately $ 0.3 million . a 0.25 % change in the level of price inflation assumption would change the pbo by
