IAS 33 EPS - Number of shares 7 / 12

Calculating the weighted average number of ordinary shares

The number of shares given in the SFP at the year-end - may not be the number of shares in issue ALL year.

So we need to know how many we had in issue on AVERAGE instead of at the end.

Well if there were no additional shares in the year then obviously the weighted average is the same as the year end - so no problem!

However, if additional shares have been issued we’ve got some work to do as follows (depending on how those shares were issued):

Total duration00:00

Full Market Price issue of shares

No problem here as the new shares came with the right amount of new resources so the company should be able to use those new resources to maintain the EPS

  • No adjustment needed (apart from time)

Bonus & Rights Issue of shares

More problematic, as the share were issued for cheaper (rights) than usual or for free (bonus).

In both cases the company has not been given enough new resource to expect the EPS to be maintained.

This causes comparison to last year problems.

  • Adjust for these (Bonus fraction)

  • Pretend they were in issue ALL year

  • Change comparative (Pretend they were in last year too)

So, how to calculate it is best explained by example:

1st January 100 shares in issue
1st May Full market price issue of 400 shares
1st July 1 for 5 bonus issue

Solution

Draw up a table like this:

DATETOTAL SHARESTIMEBONUS FRACTIONWEIGHTED AVERAGE


Now fill in the first 2 columns:

DATETOTAL SHARESTIMEBONUS FRACTIONWEIGHTED AVERAGE
1st Jan100
1st May500
1st July600


Notice how this shows the TOTAL shares. Now fill in the timing of how long these TOTALS lasted for in the year.

DATETOTAL SHARESTIMEBONUS FRACTIONWEIGHTED AVERAGE
1st Jan1004/12
1st May5002/12
1st July6006/12


Finally look for any bonus issues and pretend that they happened at the start of the year. We do this by applying the bonus fraction to all entries BEFORE the actual bonus or rights issue.

In this case the bonus fraction would be 6/5 - so apply this to everything before the actual bonus issue:

DATETOTAL SHARESTIMEBONUS FRACTIONWEIGHTED AVERAGE
1st Jan1004/126/5
1st May5002/126/5
1st July6006/12 


Finally, multiply through and calculate the weighted average:

DATETOTAL SHARESTIMEBONUS FRACTIONWEIGHTED AVERAGE
1st Jan1004/126/540
1st May5002/126/5100
1st July6006/12 300
    440
