Impact of COVID-19	Impact of COVID-19Visitor arrivals to Hawaii, the primary driver of increases in demand for gas in Hawaii, improved sequentially in the first quarter of 2022, which we believe reflects increased visitor confidence levels due to the availability of COVID-19 vaccines and a relatively low level of infections in the islands. The rate of recovery in the number of visitors to Hawaii in the future remains uncertain. COVID-19 continues to negatively affect the performance of the MIC Hawaii businesses, although the effects have diminished relative to this time last year. The additional easing of travel restrictions this quarter has resulted in an increase in economic activity and the number of primarily domestic visitors to Hawaii, but not to pre-COVID-19 levels. A significant surge in COVID-19 rates could negatively impact the number of visitors to Hawaii. Trends in the number of visitors to Hawaii and demand for gas were positive in the first quarter, although the financial performance of the Company continues to lag pre-COVID-19 periods. The number of visitors to Hawaii increased to 2.0 million for the quarter ended March 31, 2022, from 847,000 for the quarter ended March 31, 2021. The resulting improvement in hotel occupancy, restaurants patronage, and use of commercial laundry services contributed to an increase in gas consumption of 11% during the quarter ended March 31, 2022, versus the comparable period in 2021. The number of visitors to Hawaii was lower by 21% in the quarter ended March 31, 2022, and overall gas consumption was lower by 13% versus the comparable pre-COVID-19 period in 2019.
