Guidance Their own work or organisation

“After the Equitas transaction, however, the annual DCRA cost will initially increase to about $450 million a year.”

Warren Buffett, Berkshire chairman 2007 Berkshire Hathaway 2006 Letter to Shareholders (Berkshire Hathaway)

After the Equitas transaction, Berkshire's annual DCRA cost will initially increase to about $450 million a year.

Mostly true True in substance, wrong in a detail.

The second judge would not resolve this claim; the verdict shown is the first judge's.

The evidence is the person's or their organisation's own records.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Test: Berkshire's reported annual amortization of deferred charges on reinsurance assumed (DCRA) for 2007, the first full year after the Equitas transaction, as given in Berkshire's 2007 annual report/10-K or the 2007 shareholder letter. True: the 2007 charge rose from the pre-Equitas level and was within ±10% of $450 million ($405M–$495M). Mostly true: it rose and was within ±10–20% of $450M. Mostly false: it rose but was 20–35% away from $450M, or it was near $450M only in a later year rather than initially. False: it did not rise, or it was more than 35% away from $450M.

Reasoning

Berkshire's 2008 annual report gives 2007 deferred charge amortization in two parts. It was $213 million on contracts from prior years (E7) and $156 million on contracts written in 2007, mainly Equitas (E6). Together that is about $369 million. This is above the 2006 prior-year amortization of $358 million (E7), but about 18% below $450 million, which falls in the 10–20% band. The 2008 charge on prior-year contracts was $451 million (E7), close to the guided level, but the criteria test 2007, and the full-year 2006 figure is not given.
