4 terms

Reorganization financial

"such reorganization, the "Reorganization""

NAV per share financial

"the Target Fund reported a NAV per share of $11.3116"

NAV per share is the value of a fund or company's assets minus its liabilities, divided by the number of shares outstanding — think of it as the price of one slice of a pie made from all the holdings. Investors use it to judge whether a share’s market price is fair: if the market price is lower than NAV per share, shares may be trading at a discount; if higher, at a premium.

conversion ratio financial

"The conversion ratio for the Target Fund's common shares was 1.87521869"

The conversion ratio is the number of common shares an investor receives when a convertible security (like a bond or preferred share) or an exchangeable instrument is turned into ordinary stock. It matters because it tells investors how much ownership or dilution will occur — similar to knowing how many slices you get when you trade in a coupon — and directly affects the value you get from the convertible and the company’s future share count.

fractional shares financial

"cash was distributed for any fractional shares"

Fractional shares are portions of a whole share of a stock or fund, allowing investors to own less than one full unit. They make it possible to invest a specific dollar amount rather than buy whole shares, like buying a slice of a pizza instead of the entire pie. For investors this lowers the cost barrier, helps with diversification, and lets you reinvest dividends or purchase expensive stocks in small, precise amounts.
