The Gordon Model helps approximate the DCF value of a property that has a constant expected NOI growth rate in perpetuity. ![]() If a building sells for more than its replacement cost, an investor might be better off developing a new building instead of buying the existing one, and vice versa. Replacement cost gives an indication of what it would cost to build the same building today and can sometimes be used as an additional tool to estimate the value of a property. Determining the stabilized NOI of a property is a subjective matter and can result in very different valuations for the same property. While cap rates are a good “quick and dirty” tool for pricing real estate assets, students should be aware that cap rates can only be applied when using stable NOI estimates. Market cap rates change as the market perception of risk, cash flow, or growth changes. Cap rates are determined by the market as the expected yield an owner should get on a stabilized income-producing property given a certain risk level (similar to valuation of coupon-paying bonds). A cap rate is defined as stabilized NOI divided by property value (stabilized NOI/property value = Cap Rate). Nature, doi:10.1038/nature03021 ( 2004).Cap rates are generally used in real estate valuation analysis and are the inverse of a traditional corporate earnings multiple. Whitehead Institute for Biomedical Research The team's next findings are scheduled to appear in the Proceedings of the National Academy of Sciences. Grützner's colleague Willem Rens from the University of Cambridge, UK, says he has an idea, but isn't ready to discuss it yet. So what is the advantage of having so many sex chromosomes? "It's hard to speculate on how that could have evolved," says Rozen. They now plan to study the two echidna species to see if they use the same system. The result "challenges the accepted view that mammal and bird sex chromosomes evolved independently", the researchers report online in Nature 1. But they evolved from different pairs in the two classes, so scientists had believed the systems arose separately.īut because the platypus system contains elements of both, it is possible that the two systems are related. One of the platypus's sex chromosome pairs contains units similar to these, but another resembles the ZZ/ZW sex chromosome system found in birds.īird and mammal sex chromosomes both evolved from autosomal chromosomes. In humans, sex is determined by one pair of chromosomes: a woman has two X chromosomes, and a male has an X and a Y. ![]() "The platypus is a huge exception." Like a bird "Mammals are pretty boring when it comes to sex chromosomes," says geneticist Steve Rozen of the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts. They were amazed to find that five separate pairs, which join together in a chain during cell division, determine an individual's sex. But researchers had long been confused about which ones are autosomal (inherited equally by males and females), and which ones determine sex.įrank Grützner of the Australian National University in Canberra and his colleagues used fluorescent tags to study the animal's chromosomes. The platypus has 26 pairs of chromosomes in total, compared with the 23 pairs present in humans.
