Compensation “actually paid” is calculated in accordance with Item 402(v) of Regulation

S-K,

however, as required, the dollar amounts include (among other items) equity compensation that may be realizable in future periods, and as such, the dollar amounts shown do not fully represent the actual final amount of compensation earned or actually paid during the applicable years. The table below sets forth each adjustment made during the years presented in the table to calculate the compensation “actually paid,” in accordance with Item 402(v) of Regulation

S-K,

to our NEOs during each year in the table.

(3)

During 2023, our

non-PEO

NEOs consisted of Mr. Richards, Dr. Pickert, Ms. Moore and Mr. Wood. In 2022, our

non-CEO

Adjusted EBITDA is defined on page 32 and is a

non-GAAP

financial measure.

(7)

As shown in these tables, the Compensation “Actually Paid” totals represent the SCT totals for the applicable year, but adjusted as required by SEC rules to include the fair value of current and prior year equity awards that are outstanding, vested or forfeited during the applicable year, instead of the grant date value of awards granted during the applicable year.

(8)	Represents the total of the amounts reported in the Stock Awards and Option Awards columns of the SCT for the applicable year.

(9)	The fair value of equity component of the CAP calculation was determined in accordance with SEC methodology for this disclosure. Unlike the SCT, which reflects the grant date fair value of equity awards granted during the applicable year, the CAP table reflects equity fair value as follows:

•

for awards granted during the applicable year (and which are still outstanding),

the year-end

value; plus

•

for awards granted during prior years that were still outstanding as of the

applicable year-end,

the change in value as of the

applicable year-end

compared against the

prior year-end;

plus

•

for awards granted in prior years that vested during the applicable year, the change in value as of the vesting date compared against the

prior year-end;

plus

•

for any awards granted in the applicable year that vested during the applicable year, the value as of the vesting date; plus

•

the value of any dividend equivalents that were paid during the applicable year that are not otherwise included in total compensation; minus

•

for awards granted in prior years that were forfeited during the applicable year, the value as of the

prior year-end.

The specific calculations with respect to the CAP fair value of equity for the relevant years are shown in the tables below:
