Bill tenors are usually quoted in weeks, that is used to establish a trial date. A "date roll" is then applied to adjust the trial date if it falls on a non-business date (weekend or holiday). So the question is what is the UST date roll convention. The date roll is not the same thing as t...

The US Treasury Direct website does not provide an answer. Grrr. I've always defaulted to Modified Following per the ISDSA definitions - if the trial date falls on a non-business day, go forward in time to the next good business day unless that results in moving into the next month, in which case go...

Thank you for your posts. 1. I am switching on argument XLOPER xltype for error checking purposes. I have yet to find anything I can supply to the Excel Function Wizard that switches on an xltype into xltypeMulti. I can supply arguments that switch on xltype as expected into the other sub types - xl...

Any hardcore Excel C API XLL developers on the forum? I have a question or two about using the internal Excel data types, the XLOPERs, as XLL function arguments. The 2013 MS XLL SDK sample code (latest version) uses the U data registration type (XLOPER12) for XLL function arguments, and “coerces” th...

I found this old text by Kenneth Garbade (at Bankers Trust at the time) to be really good on US Treasuries. Can't find my copy but I'm certain when-issueds are covered.

Sounds rather intriguing. I cannot offer much advice about how to conduct a suitable event study. But I can offer some opinions about what happens  after  you conclude there really is a problem. None of it is fun and the worst is front-loaded. At that point, one’s professional obligation is to firs...

How does the simulation output behave as you vary the number of time steps? W h at are the accuracy and the precision of the model? What kind of simulation output and dia g nostics are you collecting?   What is the opportunity cost of the additional computational time with more timesteps? A lot depe...

Meanwhile, north of the border Canadian Conservatives are working furiously to find (manufacture) something resembling a full-time job before politics to put on his Wiki page so that the federal Conservative party leader Pierre Poilievre can claim to have done something other than politics before be...

The survey of US car owner buying intentions recently showed for the first time Tesla owners less committed to their brand than Big 3 vehicle owners.

I think I have it. Borisism can be described as simply this: “If others remain willing to give me money, being an MP or even PM is a part-time job.”

Canadians are struggling what to make of Mr Peterson. He does seem a bit distant in front of the camera these days, a bit sedated. One of our more annoying newspapers, The National Putz... er... Post, was offering mental health explanations for his behaviour a while back.    Not long ago I found a v...

The UK government has hired 50,000 additional bureaucrats to deal with Brexit. That number is said to be about equal to the number of EU employees in Brussels. The irony is delicious.   But my favourite so far is Boris’ government reduced to begging a private road charity for help in dealing with st...

A friend just had a Rolex in for service. Have you also noticed they don’t return any parts they replace in the process despite the fact that we own those parts and they don’t? I’ve never seen any Rolex purchase agreement that says they lease watches instead of selling them. I assume Rolex is trying...

P&C insurance rates in Canada require approval by provincial regulators, something that has frankly always worried me. I don’t know how finely the rate approvals are cut, but I assume the companies have convinced the regulators there are either reliability and/or safety issues with DIY solar (th...

A practical problem in transitioning to solar energy in Canada is higher property insurance costs. Is that problem evident elsewhere? Fortunately, the insurers here seem to have no similar prejudice against heat pumps.
