by $1,796,104 from 2022 to 2023 due to pay raises, new hires, increased stock compensation, and higher bonus accruals. Professional fees also increased by $190,699 from 2022 to 2023.
Other income, net, decreased to $286,190 for 2023 as compared to $717,709 for 2022 in part due to an unrealized gain recorded in 2022 of $276,000 for the valuation of the put/call options associated with the initial acquisition of a controlling interest in PERC. We exercised our call option in the fourth quarter of 2022 and acquired the remaining 39% of PERC in January 2023. We also generated approximately $92,000 less interest income in 2023 due to a decrease in CW-Bahamas’ average interest earning accounts receivable balances.

Revenue generated by our retail water operations increased to $15,344,424 in 2023 from $12,840,003 in 2022 due to a 17% increase in the volume of water sold.
