In addition to symptoms localized to the oropharynx, GABHS pharyngitis may also cause suppurative and nonsuppurative complications. Invasion of nearby structures may cause suppurative complications such as otitis media, sinusitis, peritonsillar abscess, retropharyngeal abscess, and cervical adenitis.
Determine the internal rate of return using cash flows that occur at regular intervals, such as monthly or annually. Each cash flow, specified as a value, occurs at the end of a period. IRR is calculated through an iterative search procedure that starts with an estimate for IRR â specified as a guess â and then repeatedly varies that value until a correct IRR is reached. Specifying a guess argument is optional; Excel uses 10% as the default value.
To correct this problem, a modified IRR (MIRR) is used that incorporates the cost of capital as the reinvestment rate; however, the NPV method still has the advantage when compared to the MIRR method (an example is when IRR and MIRR methods return conflicting results under certain project conditions).
