(1) To write-off uncollectible receivables from the allowance for royalty receivable account.
   
(2) Benefits related to net operating loss carry-forwards and deferred items have been fully reserved because it is not more likely than not that the Company will achieve profitable operations. The difference between the total income taxes at the federal statutory rate and the fact that no income tax benefit was recorded are attributable to the change in the valuation allowance of $17,282,000 and $17,127,000 for the periods ended December 31, 2019 and 2018 respectively. These valuation allowances are not included in Schedule II (See Note 5 to our Consolidated Financial Statements for further discussion of the Company’s tax valuation allowance).
