Let’s see some Actuarial Terminologies from Accounting Valuations point of view under US GAAP/IAS 19R:

1.

**Accumulated Benefit Obligations (ABO):**ABO is an approximate amount of a company's pension plan liability at a single point in time. ABO is estimated based on the assumption that the pension plan is to be terminated immediately; it does not consider any future salary increases. Changes in annual ABO are mainly determined by changes in service costs, interest costs, contributions by plan participants.
2.

**Projected Benefit Obligation (PBO**): A pension's projected benefit obligation (PBO) is an actuarial liability equal to the present value of liabilities earned and the present value of liability from future compensation increases.
Note: ABO differs from PBO as ABO does not includes any assumption about future compensation levels. For plans with flat benefit or non-pay related pension benefit formulas, the ABO and PBO will be same.

__Today we will see Accounting Valuation through US GAAP and IAS 19R.__

US Accounting Standard: US GAAP

International Accounting Standard: IAS 19RUS Accounting Standard: US GAAP

International Accounting Standard: IAS 19R

Now note that there are two accounting elements basically:

**Expense**and**Disclosure**.**: Cost of a plan for income statement purpose. Pension expense is the amount that a business charges to expense in relation to its liabilities for pensions payable to employees.**

__Expense__**: Display of plan’s assets and liabilities for company’s balance sheet. Assets = Liabilities + Shareholder equity.**

Today we will cover

**Expense**
By expense we mean NPPC i.e. Net Periodic Pension Cost. If NPPC is +ve it indicates a cost otherwise an income. Simple CT2 rule right !!.

Let’s look at the components of NPPC:

Let’s look at the components of NPPC:

1.

Formula:

So here

Let’s see the example:

XYZ company has NC = 24L on 1/1/2018

Expected expenses for 2018 = 1 lac and discount rate is 6%

Service cost = 24,00,000*(1+.06)+1,00,000(1+0.5*.06) = $2,647,000

**: It is expected increase in the plan’s liabilities due to additional year of benefit accrual.**__Service Cost(SC)__Formula:

**SC = NC(Beginning of year)*(1+i)+Expense*(1+0.5i)**.So here

*is cost for plan for one more year of benefit accrual and*__NC(Normal Cost)__*represents administrative expenses and we use 0.5 because we assume expenses to be evenly distributed throughout the year.*__expenses__Let’s see the example:

XYZ company has NC = 24L on 1/1/2018

Expected expenses for 2018 = 1 lac and discount rate is 6%

Service cost = 24,00,000*(1+.06)+1,00,000(1+0.5*.06) = $2,647,000

2.

Formula

Let’s see the example:

XYZ company has PBO = 90 lacs on 1/1/2018

Expected Benefit Payments for 2018 = 7 lacs

Discount rate = 6%

Interest Cost(IC): 90,00,000*(1+.06)-[7,00,000*.06*13/24] = $517,250

**This is the interest on the projected benefit obligation. It is a financial item, rather than a cost related to employee compensation.**__Interest Cost(IC):__Formula

**: PBO(Beginning of year)*i – [Expected Benefit payments*i*13/24]**

Here PBO is the liability at the beginning of year and now when we multiplied it with interest rate we get interest(simple maths) but during the year we paid benefit payments to pensioners due to which liability reduced and therefore interest cost will also reduce. So now question is why we multiplied it with 13/24 and not 0.5. Well! The answer is that benefits are paid on the first day of each month.Let’s see the example:

XYZ company has PBO = 90 lacs on 1/1/2018

Expected Benefit Payments for 2018 = 7 lacs

Discount rate = 6%

Interest Cost(IC): 90,00,000*(1+.06)-[7,00,000*.06*13/24] = $517,250

3.

Formula:

Let’s see the example:

XYZ company has Assets = 75,00,000

Expected Employer Contribution = 7,50,000 he pays on 1 July 2018 and plan follows calendar year

Return on plan assets = 7%

Expected Benefit payments = 7,00,000

Expected Expenses = 1,00,000

EROA: 75,00,000*.07-7,00,000*.07*13/24-1,00,000*0.5*.07+7,50,000*.07*6/12 = $518,208.33

Note that under US GAAP, NPPC calculation includes SC, IC, EROA and Amortizations. But under IAS 19R amortizations are not present because any gain/loss is recognized immediately.

So for US GAAP Amortizations are:

Concept behind amortization is to spread the impact of certain events over a period of time.

1. Amortization of Transition Asset Obligation/(Asset): Any gain/loss arises due to transition from one accounting standard to another. If assets exceeds the liabilities at implementation, leads to reduction in NPPC.

2. Amortization of Prior service cost: When an employer issues a plan amendment, it may contain increases in benefits that are based on services rendered by employees in prior periods. If so, the cost of these additional benefits are amortized over the future periods in which those employees active on the amendment date are expected to receive benefits.

3. Amortization of Gain/Loss: This is the gain or loss resulting from a change in the value of a projected benefit obligation from changes in assumptions, or changes in the value of plan assets.

SO NPPC = SC+IC+EROA+Amortizations

**This is the difference between the fair values of beginning and ending plan assets, adjusted for contributions and benefit payments.**__Expected Return on Assets(EROA):__Formula:

**EROA = (Assets*r) – (Expected Benefit payments*r*13/24) – (Expected Expenses*0.5*r) + (Expected contributions*r*contribution weighting)**

Here “r” represents return on asset; it is different from “i” which is the discount rate for liabilities used above. Expected Contributions are the amount paid into the plan done by employer. Contribution weighting is the weights assigned to each contribution made by employer.Let’s see the example:

XYZ company has Assets = 75,00,000

Expected Employer Contribution = 7,50,000 he pays on 1 July 2018 and plan follows calendar year

Return on plan assets = 7%

Expected Benefit payments = 7,00,000

Expected Expenses = 1,00,000

EROA: 75,00,000*.07-7,00,000*.07*13/24-1,00,000*0.5*.07+7,50,000*.07*6/12 = $518,208.33

Note that under US GAAP, NPPC calculation includes SC, IC, EROA and Amortizations. But under IAS 19R amortizations are not present because any gain/loss is recognized immediately.

So for US GAAP Amortizations are:

Concept behind amortization is to spread the impact of certain events over a period of time.

1. Amortization of Transition Asset Obligation/(Asset): Any gain/loss arises due to transition from one accounting standard to another. If assets exceeds the liabilities at implementation, leads to reduction in NPPC.

2. Amortization of Prior service cost: When an employer issues a plan amendment, it may contain increases in benefits that are based on services rendered by employees in prior periods. If so, the cost of these additional benefits are amortized over the future periods in which those employees active on the amendment date are expected to receive benefits.

3. Amortization of Gain/Loss: This is the gain or loss resulting from a change in the value of a projected benefit obligation from changes in assumptions, or changes in the value of plan assets.

SO NPPC = SC+IC+EROA+Amortizations

### Role of Generalised Linear Model in Non Life Pricing - Phase1

We will cover a series of topics relating to how Non Life Pricing is done through GLM.

But first let's see what is GLM

Let’s take the example of Weight (Y) and Height (X). The aim of linear models is to find the line of best fit through the data points.

Here is your X axis is Height and Y axis is your Weight. Y = B0 + B1x

Line of Best Fit is B0 + B1x where B0 is intercept on Y axis and B1 is the gradient.

Now the question is how that line comes?

Well, line is chosen in such a way to minimize the sum of squared error terms where error terms are distances from data points to straight line, error terms are normally distributed with mean 0 and variance σ2.

2.

We can extend our model to allow for other predictive variables. For example, we can decide that Weight can depend on height and calories consumed per day both. So here we cannot find the line of b…

### CFM vs UDD vs Balducci

Life Tables: It is a computational tool based on a specific survival model. Our
task is to generate a survival model and our output will be a life table. Life
table is based on Unitary method. lx= Expected no. of lives at age x dx= Expected no. of deaths between exact age x and exact
age x+1 NOTE: We call it expected and not actual because most of the values
will be in decimal too, so how can it be actual.

1.CFM ·It assumes that the force of mortality is constant, i.e. ux+t = ux ·If the force of mortality of a newborn is constant, it means that the expected future lifetime of this life is 1/μ no matter what age he is in. ·Survival Function in this case will decrease exponentially. ·If 0<s<t<1 then t-spx+s = tpx/spx …

*But there is a limitation of Life Tables:*It is defined only for integer ages. If we have to calculate probability of death/survival at any non-integer age we will use 3 assumptions: 1.**CFM=**Constant Force of Mortality 2.**UDD=**Uniform Distribution of death 3.**Balducci assumption**1.CFM ·It assumes that the force of mortality is constant, i.e. ux+t = ux ·If the force of mortality of a newborn is constant, it means that the expected future lifetime of this life is 1/μ no matter what age he is in. ·Survival Function in this case will decrease exponentially. ·If 0<s<t<1 then t-spx+s = tpx/spx …

### MWRR vs TWRR which is better and Why ?

We can decide between various projects that which one
is better and which one is not on the basis of different criteria such as: NPV, IRR, DPP But how can we measure the investment performance?
Well, there are basically three measures of investment performance: 1.Money
Weighted rate of return (MWRR) 2.Time
Weighted rate of return (TWRR) 3.Linked
internal rate of return (LIRR)

It is necessary to measure the performance of a fund which can be a pension fund, funds of an insurance company or funds of an asset management company. It is important for those who are responsible for the investment funds for example: trustees in case of pension fund will monitor how fund is performing i.e. they find out the rate of return of the fund and then compare it with performance of other funds. Before looking at different measures, let’s see some definitions: a.)Income generate by fund: it includes interest payments, dividends received fr…
