Deferred revenue relates primarily to consumer and customer warranties. These constitute future performance obligations and the Company defers revenue related to these future performance obligations. The Company recognized revenue, which was included in the deferred revenue liability at the beginning of the periods, of $271,179 and $367,198 in the nine months ended March 31, 2021 and 2020, respectively, for performance obligations related to consumer and customer warranties.  The deferred revenue liability was $808,488as of June 30, 2019. The Company estimates that the deferred revenue performance obligations are satisfied within one to three years and therefore uses that same time frame for recognition of the deferred revenue.
