I got a check from AEROMEX for lost luggage. the letter says their limit of loss is 1,000.00SDR's. What is SDR

Question

I thought I read somewhere the limit for international travel was $400.00 per bag, yet they say their limit is 1,000.00SDR's. the check was for over $1400.00USD, so I am assuming SDR's is a unit of currency, but whos?

Answer 1

SDR valuation
The value of the SDR was initially defined as equivalent to 0.888671 grams of fine gold—which, at the time, was also equivalent to one U.S. dollar. After the collapse of the Bretton Woods system in 1973, however, the SDR was redefined as a basket of currencies,today consisting of the euro, Japanese yen, pound sterling, and U.S. dollar. The U.S. dollar-value of the SDR is posted daily on the IMF's website. It is calculated as the sum of specific amounts of the four currencies valued in U.S. dollars, on the basis of exchange rates quoted at noon each day in the London market.
