For this week's discussion, respond to the following: projects can have cash flows where there are two sign changes of the cash flows. this creates issues with the mathematics used to solve the problems. you need to be aware of this issue and know where you could look to solve a problem with these types of cash flows (which are not that unusual). select a project from work or another project you are familiar with and discuss the project details (conceptually, this is not an analytical number crunching exercise). be sure to include what in the project creates and results in the issues that would cause the multiple roots. how many potential roots does your project have?

Insurance companies have internal controls in place to protect assets, monitor the accuracy of accounting records and encourage operational efficiencies and adherence to policies. these internal controls are generally of two types: administrative controls and accounting controls. administrative controls are the policies and procedures that guide the daily actions of employees. accounting controls are the policies and procedures that delineate authorizations of financial transactions that are done, safeguard assets, and provide reports on the company’s financial status in a reliable and timely manner. internal controls should include both preventative and detective controls. the purpose of preventative controls is to stop problems and errors before they occur. detective controls identify problems after they have occurred. preventative controls are usually more effective at reducing problems, but they also tend to be more expensive. internal controls must be flexible to adjust for changes in laws and regulations in addition to adding new products or modifying current ones. companies must also do regular analyses to ensure that the benefits of implementing the controls are worth their costs. when concerned about paying unwarranted insurance claims which type of control would be useful?
