The amount of capital usage overnight, with our Firm, is determined by amount of risk, based on longevity, capital, and type of positions being held. Many Merger guys and Pairs guys take home 30 or more times their equity of hedged positions. Naked long or shorts are generally limited to 20 times.
A risk fee (haircut) charge may apply for these positions. For example if you take home 30 times your equity in (roughly based on $$ long vs. $$ short) hedged positions, the max you'll pay is 3.6% per annum. 0-6 times free, 6-12 times = 2%, 12-18 - 4% and 18-30 times = 6%.
This is based on U.S. equities only (at this point anyway).
