Question: What kind of building are both 3 Hudson Boulevard and Manhattan Life Insurance Building considered?
Context: Manhattan Life Insurance Company, incorporated on May 29, 1850, is a life insurance company domiciled in New York but operates as a subsidiary of Manhattan Life Group in Houston, Texas. The former Asia Insurance Building () is a high-rise building formerly for commercial use, located on Finlayson Green near Raffles Place, in Singapore's Downtown Core.  The Asia Insurance Building was also known as the A.I. Building, but was renamed to Ascott Raffles Place after the Ascott Group (a division of CapitaLand) completed its redevelopment of the building into a serviced apartment residence in November 2008. Whole life insurance, or whole of life assurance (in the Commonwealth of Nations), sometimes called "straight life" or "ordinary life," is a life insurance policy which is guaranteed to remain in force for the insured's entire lifetime, provided required premiums are paid, or to the maturity date.  As a life insurance policy it represents a contract between the insured and insurer that as long as the contract terms are met, the insurer will pay the death benefit of the policy to the policy's beneficiaries when the insured dies.  Because whole life policies are guaranteed to remain in force as long as the required premiums are paid, the premiums are typically much higher than those of term life insurance where the premium is fixed only for a limited term.  Whole life premiums are fixed, based on the age of issue, and usually do not increase with age.  The insured party normally pays premiums until death, except for limited pay policies which may be paid-up in 10 years, 20 years, or at age 65.  Whole life insurance belongs to the cash value category of life insurance, which also includes universal life, variable life, and endowment policies. The Manhattan Life Insurance Building was a 348 ft tower at 64-66 Broadway in New York City completed in 1894 to the designs of the architects of Kimball & Thompson and slightly extended north in 1904 making its new address 64-70 Broadway.  It was the first skyscraper to pass 100 m in Manhattan. The New York Life Insurance Building, New York, located at 51 Madison Avenue, Manhattan, New York City, across from Madison Square Park, is the headquarters of the New York Life Insurance Company. Francis Hatch Kimball (1845–1919) was an American architect practicing in New York City, best known for his work on skyscrapers in lower Manhattan and terra-cotta ornamentation.  He was an associate with the firm Kimball & Thompson.  His work includes the Empire Building, Manhattan Life Insurance Building, and Casino Theatre (Broadway).  All but one of Kimball's work was in the United States.

Its developer is Joseph Moinian. The Supreme Life Building is a historic insurance building located at 3501 S. Dr. Martin Luther King Drive in the Douglas community area of Chicago, Illinois.  Built in 1921, the building served as the headquarters of the Supreme Life Insurance Company, which was founded two years earlier.  The company, originally known as the Liberty Life Insurance Company, was the first African-American owned insurance company in the northern United States.  Since white-owned insurance firms regularly denied black customers life insurance when the firm was founded, the firm played an important role in providing life insurance to Chicago's African-American community.  The company ultimately became the largest African-American owned business in the northern states and became a symbol of the predominantly black Bronzeville neighborhood's economic success from the 1920s to the 1950s. 35 East Wacker, also known as the Jewelers' Building, is a 40-story 159.4 m historic building in the Loop community area of Chicago, Illinois, United States, located at the intersections of Wabash Avenue, and facing the Chicago River.  It was built from 1925 to 1927, and was co-designed by Joachim G. Giaver and Frederick P. Dinkelberg.  It was once considered to be the tallest building in the world outside of New York City.  Formerly the Pure Oil Building and North American Life Insurance Building, 35 East Wacker was listed in 1978 as a contributing property to the Michigan–Wacker Historic District on the National Register of Historic Places, and was designated a Chicago Landmark on February 9, 1994.
