DISCUSSION
<br /> The rate of interest (7.75%) being charged by CaIPERS is significantly above the City's
<br /> true cost of capital. Two simple methods to determine the cost of capital are: (1) how
<br /> much interest could the City earn if it invested the $7,840,285 over a 10 year period,
<br /> and (2) what is the City's current estimated cost of borrowing? As it happens, both of
<br /> these approaches yield a true interest cost of approximately 4.5%; therefore, 4.5% is
<br /> assumed for purposes of the analysis. It should be noted that the City is currently
<br /> earning a rate of return on the investment of its idle funds of 1.8%; the 4.23% used in
<br /> Table 2 for analysis is the ten year Treasury Rate. Table 2 presents the analysis of the
<br /> savings that the City could realize if the Side Fund Loan was paid off in its entirety:

<br /> The total gross savings to the City over the 10 year period would be $3,509,653 in
<br /> interest savings from not paying the remaining interest owed to CaIPERS Side Fund
<br /> Loan. Assuming that the City pays off the Loan to CAIPERS and pays back the internal
<br /> loan at an assumed rate of 4.23%, the City could save $1,567,205. The best measure
<br /> of overall financial benefit to the City is the net present value (NPV), a calculation that
<br /> states the savings in current dollars. By applying the true interest cost of 4.50% as our
<br /> factor, the net present value savings is $1,325,385. The rule of thumb is that anytime
