Joint-Life First-Survivor Insurance Symbol

Question

I get an error when trying to produce the following symbol: Command \scriptsize invalid in math mode. I'm not sure how to get around it in this case after doing some searching...

MWE:

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{amsmath, amssymb}
\usepackage [english]{babel}
\usepackage [autostyle, english = american]{csquotes}
\begin{document}
\begin{align*}
A^{\hspace{0.35cm}1}_{\scriptsize\overbrace{40:50}:\overline{10}|}
\end{align*}
\end{document}

It would be even better if I could get the subscript written without any extra spaces (like 40:50).

lifecon does not have this symbol, to my knowledge.

If I do not customize the size on the subscript, I get the following:

enter image description here

whose numbers 40:50 are too big.

MWE:

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{amsmath, amssymb}
\usepackage [english]{babel}
\usepackage [autostyle, english = american]{csquotes}
\begin{document}
\begin{align*}
A^{\hspace{0.35cm}1}_{\overbrace{40{:}50}:\overline{10}|}
\end{align*}
\end{document}

the command is \scriptstyle not \scriptsize but script size is automatic in a subscript so you can just delete the command. use {:} to get tight spacing — David Carlisle, Mar 10 '15 at 01:45
For the annuity symbol, see the answers to http://tex.stackexchange.com/q/25008/3954 — Gonzalo Medina, Mar 10 '15 at 01:47
@GonzaloMedina - The annuity symbol is not of concern; it is trying to size the 40:50 appropriately. — Clarinetist, Mar 10 '15 at 01:48
@Clarinetist I know what your question is. Sorry for trying to suggest you how to improve your code. I promise I won't do it again. — Gonzalo Medina, Mar 10 '15 at 01:51
@GonzaloMedina - Apologies if I came off the wrong way. I didn't find anything particularly helpful on that website, to be honest. — Clarinetist, Mar 10 '15 at 01:56

The code:

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{amssymb}
\usepackage{mathtools}
\usepackage [english]{babel}
\usepackage [autostyle, english = american]{csquotes}

\def\annu#1{{% 
  \vbox{\hrule height .2pt 
    \kern 1pt 
    \hbox{$\scriptstyle {#1}\kern 1pt$}% 
  }\kern-.05pt 
  \vrule width .2pt 
}}

\begin{document}
\begin{align*}
A^{\mathclap{\phantom{\,\scriptstyle 40:50\,}1}}_{\overbrace{\scriptstyle 40:50}:\annu{10}}
\end{align*}
\end{document}

For the annuity I used the definition in the answer to Annuity notation in LaTeX.

I've propose a cleaner solution with the package actuarialsymbol. – David Beauchemin Jan 02 '20 at 21:29

This?

enter image description here

\documentclass[12pt]{article}
\usepackage[margin=2cm]{geometry}
\usepackage{amsmath, amssymb}
\usepackage [english]{babel}
\usepackage [autostyle, english = american]{csquotes}
\begin{document}
\[
A{\scriptstyle\overbrace{\scriptstyle 40{:}50}^1:\overline{10}|}
\]
\end{document}

Or replaceing both \scriptsyle by \scriptscriptstyle :

I had the same problem with the actuarial symbol and the subscript/superscript, sooo I made a package to make my life easier and help other.

Plus, I’ve add some shortcut to save time.

The project page and the CTAN.

All you need is the actuarialsymbol package.

At the beginning of the code you have to write

\usepackage{actuarialsymbol}

For the sub/superscript

\actsymb['subscripLeft']['superscriptL']{<middle>}{'subscriptR'}{'superscriptR'}

Example of output:
