[1] In 2018, the Company adopted the new ASC 606 revenue recognition guidance which applies to revenues reported beginning with the first quarter of 2018. We would have reported lower fee income of $48,746 in the first quarter and higher fee income of $16,869, $74,352 and $22,351 respectively in the second, third and fourth quarters of 2018, representing a $64,826 increase in the reported fee income for the year ended December 31, 2018 had we continued to use the accounting guidance used prior to the adoption of ASC 606.

[2] The Company incurred higher costs in the fourth quarter of 2017 due to: (i) $76,000 of stock and option compensation charges in 2017, relating to common stock and options granted to directors and employees. The Company incurred higher costs in the second quarter of 2018 due to $69,000 of stock option compensation charges in 2018 related to options granted to employees. In addition, during the third and fourth quarters of 2018 the Company incurred higher (lower) costs of $286,631 and ($8,587), respectively, relating to market valuation adjustments for warrants.

[3] Since per share information is computed independently for each quarter and the full year, based on the respective average number of common shares outstanding, the sum of the quarterly per share amounts does not necessarily equal the per share amounts for the year.
