Overview:

In Japan, a fossil of the extinct and apex predator Mosasaur, a massive marine reptile from the Late Cretaceous period, was recently discovered.

About Mosasaur

  • Mosasaurs (family Mosasauridae) were a group of large predatory marine reptiles that inhabited all of the world’s oceans during the Late Cretaceous epoch, between 90 and 66 million years ago.
  • They are related to snakes and monitor lizards and were some of the largest marine organisms of the time and some of the largest predatory reptiles, period.
  • These creatures were contemporaries of Tyrannosaurus rex and other Cretaceous dinosaurs that ruled the Earth.
  • They lived near the surface of the water since it breathed air, much as whales do.
  • They died out, along with dinosaurs and many other animals, during the mass extinction at the end of the Cretaceous Period, 66 million years ago.
  • Features:
    • Although Mosasaur species varied in length, some grew to be more than 50 feet long.
    • They had a snakelike body with a large skull, a long snout, and sharp teeth.
    • The structure of the skull was very similar to that of the modern monitor lizards, to which mosasaurs are related.
    • They had flipper-like paddles for arms and legs and a tail fin.
    • They propelled themselves by mainly moving the large fin on their tail in a side-to-side motion.
    • They were also covered in smooth scales, which were very dark in color.
    • They were carnivores.

Q1) What is Tyrannosaurus rex?

Tyrannosaurus rex, commonly known as T. rex, was a large carnivorous dinosaur that lived during the Late Cretaceous period, approximately 68 to 66 million years ago.T. rex was one of the largest carnivorous dinosaurs, with estimates suggesting it could reach lengths of up to 40 feet (12 meters) and stand about 15 feet (4.6 meters) tall at the hips.

What is Surrender Value in Insurance? Blog Image

Overview:

The Insurance and Regulatory Development Authority of India (IRDAI), recently released a crucial consultation paper on increasing the surrender value for life insurance policies.

About Surrender Value in Insurance

  • The surrender value of an insurance policy is the amount that the insurance company will pay the policyholder back when he or she decides to terminate the policy before maturity.
  • It applies only to those term insurance policies with a surrender benefit.
  • The surrender value is usually a percentage of the total premiums paid minus any applicable charges or fees.
  • How is the surrender value calculated? The surrender value calculation in term insurance policies varies from one insurance company to another. Generally, the surrender value is calculated based on the following factors:
    • Policy term: The longer the policy term, the higher the surrender value.
    • Premium paid: The higher the premium paid, the higher the surrender value.
    • Policyholder’s age: The younger the policyholder at the time of surrendering the policy, the higher the surrender value.
  • IRDIA rules for surrender value:
    • The IRDAI rules say that anyone with a term plan can give up their insurance policy.
    • However, only after the policy has been in effect for three years will the policyholder get the payout of the surrender value.
    • The IRDA decides what the policy's surrender value is for the first seven years.
    • From the third year on, the surrender value is up to 30% of the paid premium. It excludes the premium paid for the first year.
    • Between the fourth and seventh years, the surrender value could fall to up to 50% of the paid premium.
    • After seven years, the insurance company decides how much the premium should be.
    • The general rule is that the closer you are to your date of maturity when you surrender, the more money and benefits you get.

Q1) What is the Insurance and Regulatory Development Authority of India (IRDAI)?

It is an autonomous and statutory body established under the IRDA Act 1999. It is the apex body that supervises and regulates the insurance sector in India. It aims to protect the interests of policyholders, to regulate, promote and ensure orderly growth of the insurance industry in India.
