Other Expense
Other Expense	*Loss from an ongoing litigation, Elysium* During the year ended December 30, 2017, the Company incurred a write-off of approximately $746,000 in gross trade receivable from Elysium related to royalties, due to inherent uncertainty about collecting all damages sought by the Company, as well as the Company’s decision to not seek damages for any unpaid royalty payments under the License Agreement in connection with the defense of Elysium’s claims for patent misuse and unjust enrichment. As a result of this write-off and after further analysis, the Company made an adjustment to the total allowance amount from ($800,000) to ($500,000).

The entire disclosure for other income or other expense items (both operating and nonoperating). Sources of nonoperating income or nonoperating expense that may be disclosed, include amounts earned from dividends, interest on securities, profits (losses) on securities, net and miscellaneous other income or income deductions.
