decreased by 11.3 percent compared to fiscal 2020 , reflecting end market softness and covid-19 related volume declines in the architectural framing systems , architectural glass and lso segments , partially offset by increased volume in the architectural services segment , driven by execution of projects in backlog . fiscal 2020 compared to fiscal 2019 net sales in fiscal 2020 decreased by 1.1 percent compared to fiscal 2019 , driven by expected project timing-related decreases within the architectural services segment and by lower volumes at certain businesses within the architectural framing systems segment , partially offset by improved volume in the architectural glass segment . performance the relationship between various components of operations , as a percentage of net sales , is provided below . replace_table_token_5_th fiscal 2021 compared to fiscal 2020 gross margin was 22.4 percent in fiscal 2021 , a decrease of 60 basis points from fiscal 2020. this decrease was driven by the impact from lower volumes due to end market softness and covid-19 related project delays , partially offset by strong project execution in the architectural services segment . total selling , general and administrative ( sg & a ) expense for fiscal 2021 , including impairment expense on goodwill and intangible assets noted in the table above , was 20.3 percent , an increase of 360 basis points from fiscal 2020. this was driven by a $ 70.1 million impairment expense taken within the architectural framing systems segment , partially offset by a $ 19.3 million gain on the sale-leaseback of a building within the large-scale optical segment and $ 7.4 million of income related to a new markets tax credit transaction within the architectural glass segment . in addition , we received a benefit of $ 7.4 million in fiscal 2021 , as a result of a canadian wage subsidy program offered to support canadian business impacted by the covid-19 pandemic , thereby offsetting cost actions that would have been taken had this subsidy not been secured . net interest expense declined by 30 basis points compared to the prior year , due to the lower average debt balance in fiscal 2021 and a favorable one-time legal settlement impacting interest . the effective tax rate for fiscal 2021 was 31.7 percent , compared to 22.4 percent in fiscal 2020 , primarily due to nondeductible goodwill impairment in canada and the impact of the unfavorable permanent items in relation to reduced earnings in fiscal 2021. fiscal 2020 compared to fiscal 2019 gross margin was 23.0 percent in fiscal 2020 , an increase of 210 basis points from fiscal 2019. this increase was driven by project-related charges of $ 40.9 million incurred in fiscal 2019 on certain contracts acquired with the purchase of efco . the 19 increase was also driven by operating improvements in the architectural glass segment , partially offset by manufacturing difficulties in certain of the businesses in the architectural framing systems segment and reduced operating leverage in the architectural services segment , based on timing of project activity . sg & a expense for fiscal 2020 was 16.7 percent , an increase of 60 basis points from fiscal 2019. this was primarily driven by costs for outside advisors and legal fees , including cooperation agreement advisory costs , in addition to higher

segment analysis architectural framing systems replace_table_token_6_th fiscal 2021 compared to fiscal 2020. net sales decreased 16.9 percent , or $ 115.7 million , from fiscal 2020 , primarily reflecting lower order volume for short lead-time products and market-related project delays . story_separator_special_tag we evaluated goodwill on a qualitative basis prior to and subsequent to this change and concluded that no adjustment to the carrying value of goodwill was necessary as a result of this change . for our fiscal 2021 annual impairment test , we elected to bypass the qualitative assessment process and to proceed directly to comparing the fair value of each of our reporting units to carrying value , including goodwill . if fair value exceeds the carrying value , goodwill impairment is not indicated . if the carrying amount of a reporting unit is higher than its estimated fair value , the excess is recognized as an impairment expense . we estimate the fair value of a reporting unit using both the income approach and the market approach . the income approach uses a discounted cash flow methodology that involves significant judgment and projections of future performance . assumptions about future revenues and future operating expenses , capital expenditures and changes in working capital are based on the annual operating plan and other business plans for each reporting unit . these plans take into consideration numerous factors , including historical experience , current and future operational plans , anticipated future economic conditions and growth expectations for the industries and end markets in which we participate . these projections are discounted using a weighted-average cost of capital , which considers the risk inherent in our projections of future cash flows . we determine the weighted-average cost of capital for this analysis by weighting the required returns on interest bearing debt and common equity capital in proportion to their estimated percentages in an expected capital structure , using published data where possible . we used discount rates that are commensurate with the risks and uncertainties inherent in the respective businesses and in the internally developed forecasts . the market approach uses a multiple of earnings and revenue based on guidelines for publicly traded companies . based on these analyses , estimated fair value exceeded carrying value at six of our eight reporting units . however , driven by a decline in market conditions , partially due to covid-19 and the ongoing uncertainty related to how some of our end markets will perform in a post-covid environment , at two reporting units within the architectural framing systems segment , efco and sotawall , carrying value was in excess of the concluded fair value . for these reporting units , we utilized a weighted-average cost of capital of 12.1 percent in determining the discounted cash flows and a long-term growth rate of 3.0 percent . as a result , as of february 27 , 2021 , we incurred goodwill impairment expense of $ 46.7 million and $ 17.1 million in our efco and sotawall reporting units , respectively . the discounted cash flow projections used in these analyses are dependent upon achieving forecasted levels of revenue and profitability . if revenue or profitability were to fall below forecasted levels , or if market conditions were to decline in a material or sustained manner , further impairment could be indicated at these or our other reporting units and we could incur an additional non-cash impairment expense that would negatively impact our net earnings . indefinite-lived intangible assets we have intangible assets for certain acquired trade names and trademarks which are determined to have indefinite useful lives . we evaluate the reasonableness of the useful lives and test indefinite-lived intangible assets for impairment annually at the same measurement date as goodwill , the first day of our fiscal fourth quarter , or more frequently if events or changes in circumstances indicate that it is more likely than not that the asset is impaired . we bypassed a qualitative assessment and performed a quantitative impairment test to compare the fair value of each indefinite-lived intangible asset with its carrying 24 value . if the carrying value of an indefinite-lived intangible asset exceeds its fair value , an impairment expense is recognized in an amount equal to that excess . if an impairment expense is recognized , the adjusted carrying amount becomes the asset 's new accounting basis . fair value is measured using the relief-from-royalty method . this method assumes the trade name or trademark has value to the extent that the owner is relieved of the obligation to pay royalties for the benefits received from the asset . this method requires estimation of future revenue from the related asset , the appropriate royalty rate , and the weighted average cost of capital . the assessment of fair value involves significant judgment and projections about future performance . in the fair value analysis , we assumed a discount rate of 12.6 percent , royalty rates ranging from 1.5 or 2.0 percent , and a long-term growth rate of 3.0 percent . based on our analysis , the fair value of each of our trade names and trademarks exceeded carrying amount , except for the efco tradename . the fair value determined for the efco tradename exceeded carrying value by $ 6.3 million and this amount was recognized as impairment expense in the fourth quarter ended february 27 , 2021. in addition , the fair value determined for the sotawall tradename did not exceed carrying value by a significant margin . if our discount rate were to increase by 100 basis points , the fair value of this tradename would fall below carrying value , which would indicate impairment . we continue to conclude that the useful lives of our indefinite-lived intangible assets is appropriate . if future revenue were to fall below forecasted levels or if market conditions were to decline in a material or sustained manner , further impairment could be indicated on this or another indefinite-lived intangible asset . reserves for disputes and claims regarding product liability , warranties and other project-related contingencies
