in Internal Control over Financial Reporting

controls and increase efficiency, while ensuring that we maintain an effective internal control environment.

Changes may include

such activities as implementing new, more efficient systems, consolidating activities and migrating processes.

were no significant changes in our system of internal control over financial reporting (as defined in Rule 13a-15(f) under the

Exchange Act) during the quarter ended December 31, 2020, that have materially affected, or are reasonably likely to materially

affect, our internal control over financial reporting.

Limitations on Internal Controls

should be noted that any system of controls, however well designed and operated, can provide only reasonable and not absolute

assurance that the objectives of the control system are met.

In addition, the design of any control system is based in part upon

certain assumptions about the likelihood of certain events.

Limitations inherent in any control system include the following:

in decision-making can be faulty, and control and process breakdowns can occur because of simple errors or mistakes;

can be circumvented by individuals, acting alone or in collusion with others, or by management override;

design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there

can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions;

time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with associated

policies or procedures;

design of a control system must reflect the fact that resources are constrained, and the benefits of controls must be considered

relative to their costs.

of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control

issues and instances of fraud, if any, have been detected.
