(c)	Intangible assets. Reflects the preliminary purchase accounting adjustment for estimated intangible assets based on the acquisition method of accounting.

(1)	Reflects the adjustment to increase the basis in intangible assets to estimated fair value. The estimated fair value is expected to be amortized over the estimated useful lives. The fair value and useful life calculations are preliminary and subject to change.

The assumed statutory tax rates do not take into account any possible future tax events that may impact the combined company.

---

(g)

Earnings per common share. The following table provides the pro forma weighted average number of basic and diluted common shares outstanding for the nine months ended September 30, 2018, and the year ended December 31, 2017. Diluted shares outstanding include potential dilution of common stock equivalent shares that may occur if securities to issue common stock were exercised or converted into Common Stock at the maximum conversion rate. Diluted earnings per common share applies the if-converted method by adjusting for the more dilutive effect of the Series B Preferred Stock as a result of either its accumulated dividend for the period in the numerator or the assumed-converted common share equivalent in the denominator. No adjustment for the shares issuable on conversion is reflected in the computation of the pro forma diluted earnings per common share for the nine months ended September 30, 2018 because the assumed conversion of those shares would be anti-dilutive.
