Richardson has mastered a great amount of difficult and diffuse information.
Their precise amount is difficult to reckon, because deals vary and details are seldom disclosed publicly.
This small amount is difficult to quantify except at certain wavelengths, where the solar spectrum is attenuated (Fraunhofer lines).
The role has a considerable amount of difficult dancing, too; it was easy to see why Mr. Stiefel passed on it.
"We've made a tremendous amount of difficult changes and reshaped what the company is doing and where it's going," Mr. Armstrong said later in an interview.
"Getting a large amount is difficult," he added, because most nations carefully regulate who can buy such explosives, though civilian experts can sometimes get licenses to use them for demolition and mining.
Although that amount is difficult to confirm -- and AJE's cramped and spartan offices in downtown Washington show little evidence of big spending -- the news-gathering operation doesn't appear to be starved for resources.
This amount is difficult to afford in the current circumstances, especially as so many people have not received their salaries due to the bank and post offices and foreign exchange centres being closed, and the extreme difficulty of movement in the city.
But S&P said it believes AIG will "ultimately recover a meaningful portion of the 2007 unrealized market valuation loss, but the timing and the amount are difficult to estimate".
