A little while ago William S. Morris, an Applicant’s attorney, told me that the Ogilvie adjustment calculation could be further simplified.  ((Photo courtesy of Dahveed76)) He suggested the following ((I’m paraphrasing here)) :

  1. Earnings Loss ((PIESSE = Post Injury Earnings of Similarly Situated Employees)) ((PIEA = Post Injury Earnings of Applicant))
    1. L = (PIESSE – PIEA) / PIESSE
  2. Individualized Proportional Earnings Loss
    1. = (WPI / L) / 100
  3. DFEC Adjustment Factor
    1. = ([1.81/a] * .1) + 1
    2. = ( (1.81 * .1)/a) + 1
    3. = (.181/a) + 1
    4. = 1 + (.181/a)
  4. Ogilvie DFEC Adjusted Rating
    1. = WPI * DFEC Adjustment Factor
    2. = WPI * (1 + (.181/a) )
    3. = WPI * (1 + (.181 / Individualized Proportional Earnings Loss) )
    4. = WPI * (1 + (.181 / ( (WPI / L) / 100) ) )
    5. = WPI * (1 + (18.1 / ( (WPI / L)  ) )
    6. = WPI * (1 + (18.1 * (L/WPI) ) )
    7. = WPI + (18.1 * L)
  5. Conclusion
    1. If the injured workers’ individualized proportional earnings loss is outside all of the FEC ranks, you may calculate the Ogilvie adjustment by adding (18.1*Earnings Loss) to the WPI.

The only flaw with the proofs offered by William and myself is that they are too exact.  The WCAB in Ogilvie never sets forth the exact process for performing the Ogilvie adjustment calculation – so the only official method involves rounding to different significant figures at different places.  Thus, a calculation performed in strict accordance with the WCAB in Ogilvie and through one of these mathematical proofs would differ very slightly.

You may not want to hear this, but Ogilvie II is probably worse for Defendants than Ogilvie I.   ((Photo courtesy of Lawrence Whittmore))  Check out page 32:

if within five years of the date of injury it later becomes clear that the employee’s individualized proportional earnings loss is significantly higher or lower than anticipated, a party may seek to reopen the issue of permanent disability by challenging the originally used DFEC adjustment factor.

I think we can expect to see a petition to reopen on any case that settled prior to 2/3/2009.  ((February 3, 2009 is the day Ogilvie I came out.))

UPDATE: DOWNLOAD THE MATHEMATICAL PROOF AS A PDF!

Get ready to stop paying people to do Ogilvie calculations, recycle your Gearheart/Gerlach handouts, and delete your Frost Excel spreadsheet. ((Sorry Jeff, Mark, Mark, and Ray!))  We’re about to go all “Beautiful Mind.”

Yesterday while at the Oakland WCAB an Applicant’s attorney mentioned he noticed an interesting trend in the Ogilvie formula.  ((Thank you “S”!  Unfortunately, he did not want to be named.)) ((Man, I *wish* I could take credit for this observation.)) He said that whenever he does an Ogilvie calculation for someone with a 100% earnings loss and a modest WPI, the WPI is always increased by 18.  ((Not multiplied by 18, but an addition of 18.))

I ran a number of test calculations on this theory and it appeared to be right.  My calculations show that up to a WPI of 44 the increase appears to always be 18.1, but the last “0.1” always gets rounded down.  However, appearing to be right just isn’t good enough for me.  And, because I am just truly that nerd, here’s the fully mathematical proof:

Let’s break down the calculations at the heart of Ogilvie:

  1. Earnings Loss ((PIESSE = Post Injury Earnings of Similarly Situated Employees)) ((PIEA = Post Injury Earnings of Applicant))
    1. = (PIESSE – PIEA) / PIESSE
    2. = ($1.00 – $0.00) / $1.00
    3. = $1.00 / $1.00
    4. = 1
    5. = 100%
  2. Individualized Proportional Earnings Loss
    1. = (WPI / Earnings Loss) / 100
    2. = (WPI / 100% )/100
    3. = (WPI / 1) / 100
    4. = WPI / 100
    5. Thus, for any WPI less than 45 and a total loss of earnings, the Individualized Earnings Loss will always be less than 0.450 in Table A.
  3. DFEC Adjustment Factor
    1. = ([1.81/a] * .1) + 1
    2. = ( (1.81 * .1)/a) + 1
    3. = (.181/a) + 1
    4. = 1 + (.181/a)
  4. Ogilvie DFEC Adjusted Rating
    1. = WPI * DFEC Adjustment Factor
    2. = WPI * (1 + (.181/a) )
    3. = WPI * (1 + (.181 / Individualized Proportional Earnings Loss) )
    4. = WPI * (1 + (.181 / (WPI / 100) ) )
    5. = WPI * (1 + (.181 * 100 / WPI ) )
    6. = WPI * (1 + (18.1/ WPI ) )
    7. = WPI * ( (WPI/WPI) + (18.1/ WPI ) )
    8. = WPI * (WPI + 18.1/ WPI )
    9. = WPI * (WPI + 18.1/ WPI )
    10. = WPI + 18.1
  5. Conclusion
    1. If you have an Applicant with a 100% post injury earnings loss and a WPI of 44 or less, you should rebut the FEC and arrive at an adjusted WPI that is equal to the original WPI plus 18.1.

Therefore, I propose a new Ogilvie formula that will be easy for anyone to remember:

  • Step 1: If the injured worker has a 100% earnings loss and a WPI of 44 or less, add 18.1 to the WPI and round down.
  • Step 2: If the injured worker has less than 100% earnings loss or a WPI of 45 or higher, go to Step 3.
  • Step 3: For heaven’s sake, just make your life easier and use the calculators here at PDRater.com.

I had an interesting e-mail exchange with a friend (and fellow workers’ compensation professional) the other day. ((Photo courtesy of Street Fly JZ))

We were discussing the impacts of Ogilvie on 2005 schedule ratings.  He had asked me whether I intended to update the 2005 permanent disability rating calculator to include FEC Ranks after the scheduled 8.  I believe he had suggested FEC Ranks 9 through 20.

I have no intention of manufacturing FEC Ranks 9 through 20 for the following reasons:

  • Maintaining Standards. The entire point of a rating schedule is to allow a standardized method for calculating disability and expressing those disability calculations.   If I invented my own FEC Rank system beyond the scheduled 1-8 Ranks, I would essentially be creating my own rating calculation system.  I’ve gone to considerable lengths to ensure that the rating strings produced by these permanent disability calculators are as standardized, recognizeable, and universal as possible.
  • FEC Ranks are Irrelevant. The FEC Rank system is a simplified method of applying DFEC adjustment factors.  When you use the FEC Rank of a particular body part to adjust the standard using the charts on pages 2-6 and 2-7 of the 2005 PDRS (permanent disability rating schedule), what you’re really doing is essentially multiplying your standard disability against the FEC adjustment factor associated with the particular FEC Rank for the body part in question.  An FEC Rank is only useful for telling you the appropriate FEC adjustment factor to apply to the standard disability.  Thus, FEC Ranks are irrelevant and FEC adjustment factors are all important.
  • Arbitrary FEC Ranks. FEC Rank 1 has an FEC adjustment factor of “1.100”.  However, using the Ogilvie DFEC rebuttal formula, it is possible to end up with very low FEC adjustment factors.  In extreme circumstances it would be possible to have a negative FEC adjustment factor.  The only way to resolve this would be to have several possible negative FEC Ranks.  Besides being somewhat silly, worrying about additional FEC Ranks ((Both higher and lower than the normal 8)) misses the point.  If you’re using the Ogilvie DFEC rebuttal formula properly, the result will be a new FEC adjustment factor.  If you already have the FEC adjustment factor, you have no need for the FEC Rank!

When I had discussed the impact of Ogilvie earlier, I had pointed out that in some cases the resulting formula will dictate that you use a different FEC Rank than the one indicated by the affected body part.  In other cases you will need to use an entirely new FEC adjustment factor.  In order to keep the 2005 disability calculator current I will eventually have to create a way for the user to override a body part’s standard FEC Rank and specify a new FEC Rank or their own FEC adjustment factor.

I’m not in any particular rush to develop this feature since Ogilvie seems to require three years of post-injury earnings.  I doubt we’re going to see litigation begin in earnest over Ogilvie issues for another 18 to 24 months.

Professor, tell me more of this DFEC rebuttal calculator...
Professor, tell me more of this DFEC rebuttal calculator...

Earlier today I installed an Ogilvie v. City and County of SF DFEC Rebuttal calculator into the free workers’ compensation calculators page on this website.  ((Photo courtesy of Draggin)) ((I had this EXACT same calculator as a kid!)) ((Why, how did you spend your Friday night?)) For the moment it is only available to people who have signed up for this website and asked to be a beta tester.  If all goes well, I’ll flip a switch and make it available to the public on Monday morning.

At the moment it requires four pieces of information:

  1. FEC Rank (re: body part in question)
  2. Standard disability (re: body part in question)
  3. Post-injury earnings for Applicant
  4. Post-injury earnings for employees similarly situated to Applicant

Once you add in that information, click “Calculate” and it should crunch through the formula and give you a response.  The WCAB in Ogilvie suggested several possible outcomes to this formula:

  • The “Individualized Loss Ratio” for the injured worker is the same or within the range for the current FEC Rank for the affected body part.  In this circumstance, the 2005 DFEC has not been rebutted.
  • The “Individualized Loss Ratio” for the injured worker is within the range of one of the other seven FEC Ranks.  Here, the DFEC portion of the 2005 Permanent Disability Rating Schedule might be rebutted.
  • The “Individualized Loss Ratio” for the injured worker is outside the range of all eight FEC Ranks.  In this circumstance, you could end up with a new FEC Adjustment Factor much higher or lower than any FEC Adjustment Factor associated with the eight FEC Ranks.  Here, the DFEC portion of the 2005 Permanent Disability Rating Schedule might be rebutted.

Obviously, there are innumerable factors that go into considerations of whether a Judge (or the WCAB) would find the DFEC portion of the 2005 Permanent Disability Rating Schedule to be rebutted.  This calculation and the information relied upon in performing this calculation cannot be taken as a guarranteed method of rebutting the DFEC portion of the 2005 Permanent Disability Rating Schedule.

If you’re not a registered user for this website, its free to sign up and free to use all the workers’ compensation calculators.  That’s right: free as in free.
