Our band instrument sales are influenced by trends in school enrollment, school budgeting and the prevalence and popularity of extracurricular music education. Over 50% and 45% of Conn-Selmer net sales in fiscal years 2021 and 2020, respectively, and over 46% and 49% of Conn-Selmer net sales in the three months ended March 31, 2022 and 2021, respectively, were generated through our preferred dealer network to schools and families who participate in beginning music education programs. Of the remaining sales, many are used by students in marching bands, concert bands, orchestras and other school-related performances. Due to the suspension of in-person schooling and extra-curricular activities for a significant part of fiscal year 2020 due to COVID-19, our Band segment net sales decreased significantly in fiscal year 2020 from historical levels, but recovered significantly in fiscal year 2021 as schools and concert halls re-opened.

Gross Profit and Gross Margin
Our operating results are impacted by our ability to convert net sales into higher gross profit, which we monitor using the metric gross margin. Gross margin measures gross profit as a percentage of net sales. We define gross profit as net sales less cost of sales. Our cost of sales is largely variable, enabling us to align costs to production levels and to maintain consistent gross margins.
