It Cost JPMorgan $1.5 Billion to Value Its DerivativesRightBy Matt Levine - Jan 15, 2014
Last quarter, JPMorgan's financial results included a $1.5 billion loss due to implementing afunding valuation adjustment in its accounting for uncollateralized over-the-counter derivatives
and -- wait, where are you going? Somewhere where people don't talk about accounting and
derivative valuation? Oh, yeah, okay, that's fair, I cannot really argue with you. Go in peace.If you want to stick around, though, we can talk about it, because I think it's pretty neat.Conceptually, derivatives are contracts that involve exchanging (normally uncertain) cash flows
over time. So the way to value a derivative, loosely speaking, is to guess what those future cash
flows are likely to be, and then discount them back to present value. But it turns out that banks
mostly hedge derivatives by trading in the underlying stock or currency or commodity orwhatever, or by trading offsetting derivatives in the interdealer market. What this means is that
you should -- in theory! -- have no stock price or currency or whatever risk, and so you can guess
those cash flows on a "risk-neutral basis." Similarly, since you have no risk, you can discount your
cash flows on a risk-free basis.
That's the textbook, Black-Scholes-y way of valuing derivatives. But recent years have provided
many reminders that people don't always pay what they owe on derivatives, so your risk-free cash
flows can be risky, even if they have no risk to the underlying stock or interest rate or currency or
whatever. There are two main ways of dealing with that fact, which are:1. Price it, or2. Collateralize it.
Both have their points. So there has been a big push to move derivatives onto exchanges, toincrease collateralization requirements, etc., etc. If all your derivatives are perfectly collateralized --
with instantaneous movement of cash to cover all liabilities -- then your cash flows go back to
being risk-free and you can live in a Black-Scholes world.But some derivatives don't work well with collateral or on exchanges: Corporations like to get
hedge accounting on their interest-rate swaps, for instance, and so don't like to collateralize.Sovereigns also have a thing about not collateralizing. So banks tend to have some big chunk of
uncollateralized derivatives; for JPMorgan it's around $50-odd billion of uncollateralizedreceivables (that is, money that clients "owe" JPMorgan on derivatives, or the in-the-money value

DVA, CVA and FVAaaaaaaargh!
Much accounting intrigue in JPMorgan’s recently-released fourth-quarter results.According to the bank, it incurred a $1.5bn hit to net revenue after “implementing a fundingvaluation adjustment.”
What is a funding valuation adjustment, we hear you cry?
It is this, according to JPMorgan’s handily-presented slide:
The sudden appearance of FVA is a stark reminder of some pretty massive post-crisisaccounting changes at the banks. No longer are derivatives simply the net discounted valueof each leg. Rather the bank’s own credit quality (debt valuation adjustment – DVA), andthat of its counterparty (credit valuation adjustment – CVA), as well as that mysteriousFVA.

No monetization of windfall prior to default: include FCA in price
Otherwise have negative drift while alive

Different ways to combine
Different splits
(CVA + DVA) + FCA = bilateral CVA + FCA
CVA + (FBA + FCA) = unilateral CVA + FVA
Setup 1: Unilateral CVA desk + Treasury
Setup 2: Bilateral CVA desk + Treasury
Setup 3: Bilateral CVA desk + Funding Unit

General formulation - replication arguments
General close-outs
V̂ (t,S , 1, 0) = gB(MB ,X ) Bank B defaults first,
The collateral X can be a complicated process, e.g. depends on V
MB/C are the close-out amounts as per CSA, e.g. ISDA
Regular close-outs: MB/C = V
Example: regular bilateral close-out without collateral
gB = V+ + RBV−
gC = RCV+ + V−
Boundary conditions (II): Examples
Example of different close-outs
Type gB(MB,X) gC(MC,X)
Regular bilateral close-outs M+B + RBM

Hedge Portfolio Π(t):
Market factor and counterparty risk hedges PC (t) and S(t)P1(t) and P2(t) - two own bonds of different recoveriesβS and βC - secured funding/repo for S and PC
balance sheet feedback effect doesn’t helpEven if new funding for derivatives position is at new rate, this hasonly marginal impactOwn credit adjustment on existing debt does not help eitherIn fact, it would just bring the loss forward

9 Conclusions
Accounting for FVA
Are you an accountant?
No
Has any bank started accounting for FVA?
In 2012 results, four banks have started to account for FVA
RBS, Barclays, GS, LLoyds
2013 has seen some more
JPM, DB, Nomura
Is there a market consensus?
Market consensus is still evolving
But there seems to be general agreement that funding costs shouldbe accounted for
Accounting for FVA (ctd.)
Which funding spread to use?
For accounting purposes, assets valued at realizable prices
So accountants like to use a ”market funding spread” rather thanidiosyncratic
E.g. JPM seems to have accounted for a ”market funding spread” of50bps - with idiosyncratic one around 70bps
How to determine a ”market funding spread”?
Still, economic cost encountered will be driven by the idiosyncraticspread
So realised economic value of a trade may not accrue to theaccounted value
Accounting for FVA (ctd.)
Is the economic value or the fair value accounted for?
Can be both (see Albanese and Andersen [4] )
Are FCA, FBA, FVA on netting sets, funding sets or bank-wide?
Realised economic value depends on the funding strategy
For the strategies presented above, FCA and FBA are calculated onnetting sets ...
... and they are additive across netting sets
FVA = FCA + FBA is linear, so does not depend on how it’s added
There are other strategies, where FCA and FBA are non-additive
e.g. investing surplus cash risk-free, see Albanese and Andersen [4]
DVA (structured notes and derivatives) of USD 2.5bln
uncollateralised derivatives payables USD 50 bln with 5 yearsaverage lifetime
added over netting units
Case study (ctd.)
Case study: back of the envelope accounting
DVA to FBA:
move from CDS to market funding spreadso scale down by 50bps/65bpsloss of USD 577 mio
FCA:
cost of roughly USD 50 bln * 50 bps/yr * 5 yr = USD 1250 mio
Overall loss of about USD 1.8 bln
Accounting for FVA (ctd.)
Will results fluctuate wildly with funding spread once on FVA?
No, not really
In fact, funding spread sensitivity smaller than for bilateral CVA
FCA has opposite sign to FBA/DVA, so expect some cancellation
But what about CVA then?
systemic risk and some idiosyncratic can be hedged out
Accounting for FVA (ctd.)
Still sensible to hedge DVA/FBA by selling protection on basket offinancials?
Depends
It’s not really a hedge against idiosyncratic risk of own default
Could be used to hedge remaining FVA risk to market funding spread
But induces noise from defaults in the basket
In the end it’s a trading strategy - earn premium and pay when thereis a default in the basket

Conclusions
Funding and DVA are intrinsically linked
Different funding strategies
... imply different funding costs
... and economic values for derivatives
FCA
... depends on funding strategy employed
... corresponds to expected hedge error upon own default
... ensures bank shareholders don’t loose money while bank alive
Balance sheet and funding
... are closely linked
... relationship and feedback effects not straight forward in practice
... strong feedback effects only if credit were floating
