A. Written Work/s ACTIVITY 1 Directions: Solve the following problems. 1. Your mom decided to join their office cooperative (an organization owned and run by bits members who share profits and benefits) and agreed to contribute P 1,000 per month beginning in January 2019 which will earn 3% interest compounded monthly. How much will be the future value of your mom's contribution at the end of April 2019? 2. Your dad applied for a term life insurance (provides the insured person with a coverage for a specified period of time of one, five or more years), He got a flexible policy (allows the insured person to change certain components of the insurance plan) because some payment options include a policy payout (insurance proceeds) as soon as the target period achieved or upon contingency (death or accident). Some companies offer insurance products that can be availed only upon death. Because of this better option, your dad decided to avail of insurance A's flagship insurance product, Your dad's contribution per year is P20,090 that earns 6% compounded monthly for 20 years. How much will be paid out to your dad after 20 years by insurance A?Deferred Annuity A deferred annuity is an annuity in which the first payment is not made at the beginning nor at the end of the payment interval but at a later date. The length of time when these payments are made is called the period of deferment. The first payment is made one period after the period of deferment. Thus, the annuity that is deferred for six periods will have the first payment at the end of 7 periods. Likewise, in an annuity whose first payment is made at the end of the 7 periods, the annuity is deferred for,6 months. PRESENT VALUE AND FUTURE VALUE OF DEFERRED ANNUITY The present value PV of a deferred annuity is given by the formula al where py = Present Values p =Regular payment i = rate per conversion period( period . where's is the annual rafe and K is the number of conversion periods = number of paying periods (n = to K where | is the number of years) number of deferre The future value PV of a deferred annuity is given by the formula: most off binblind sonammoho stangorges gniew estrune tions FV = p (1+1= Aaronomit brin easalaud where UNION ONT FV = Future Value P = Regular payment him aity, Nowlad i = rate per conversion period (i = 7. where r is the annual rate and K is the number of conversion periods) 25016V 9103 n = number of paying periods (n = t : K, where t is the number of years) ;on) Note: the future value of a deferred annuity is the same as the future value of simple ordinary annuity.

How about in the general annuity? How to differentiate from simple annuity from general annuity? In general annuity we focus on the computation of deferred annuity, present value and future value of deferred annuity, general ordinary annuity, present value of general annuity due, future value of general annuity due. Different examples are given for more understanding of the lesson. Based on the given sample problems you can identify which formula are you going to use in each situation.
