Please compute the current $($before$-$tax$)$ cost of each of our two largest sources of long$-$term capital:

$$ We have a variety of bond offerings at different maturities. A typical one is a recent offering of senior unsecured notes. These were issued in $2019$ with a maturity in $2029.$ They sold for $$99\mathrm{.}17$ per $$100$ face value and carry a $3\mathrm{.}9\%$ annual coupon.

$$ Shares of our common stock have been trading around $$68$ per share. We recently paid a $$3\mathrm{.}60$ dividend per share that has been growing at around $1\%$ per year.

Additionally, to address our capital structure balance, examine:

$-$ our debt$-$equity mix and our timing mix of capital.

$-$ calculate our degree of operating and financial leverage and assess how this compares with our peers.

$-$calculate our current levels of net working capital.

$-$calculate our debt$-$to$-$assets ratio and times$-$interest$-$earned ratio.

Evaluate if any adjustments to our overall capital structure are needed.

Assumptions:

$$ Assume all costs of good sold are variable costs while other operating expenses are relatively fixed given our current operations.

$$ Our current assets vary significantly quarter$-$to$-$quarter. Based on trends, assume that $40\%$ of our current assets are effectively $$permanent$$ for our current operations.
