William Harrison's retirement-planning letter for the people Sirmium Capital serves. One decision per edition for FDNY, NYPD, veterans, and federal retirees, in plain English, grounded in the actual rules.
Quick Answer
What is The Retirement Brief?
It is Sirmium Capital's retirement-planning letter series, written by our Chief Investment Officer, William Harrison. Each edition takes one decision that New York's first responders, veterans, and federal retirees actually face, a pension worry, a rollover you cannot undo, the tax map of your paycheck, and lays out the rules in plain English. Past editions are free to download below, and you can subscribe to get each new one. This is educational planning information, not personalized investment, legal, or tax advice.
The Letter
Each edition speaks to a specific service: NYPD and FDNY pensions, first-responder and veteran rollovers, the veteran and federal tax map. Real rules, not general tips.
Every claim traces back to the constitution, statute, or IRS guidance behind it, with the sources listed. Written to be read once and trusted.

Written By
Founder & Chief Investment Officer
William leads Sirmium Capital's investment and planning process. He writes every edition of The Retirement Brief himself, so what you read is the same thinking that guides how the firm advises the families it serves, not a marketing summary of it.
The approach is simple: take one decision a first responder, veteran, or federal retiree actually faces, and lay out the rules clearly enough to act on.
The Editions
For NYPD & FDNY
Whether a budget shortfall can reach your earned pension, why Article V, Section 7 of the New York State Constitution makes it a contract that cannot be diminished, and why every reform arrives as a new tier for future hires. Keeps the pension, the VSF, and COLA straight as three separate promises.
Read (PDF)For First Responders & Veterans
The one-way door in your 457 or Thrift Savings Plan. Once you separate, those dollars can often be reached before 59 and a half without the early-withdrawal penalty, and rolling them into an IRA can quietly give that access away. How to read the sign before you sign.
Read (PDF)For Veterans & Federal Retirees
Your retirement paycheck arrives in pieces, and each follows its own rule. Sort VA compensation, military retired pay, TSP, FERS, and Social Security into tax-free, taxable, and partly taxable, see where your state sits, and understand why the order you draw matters as much as the rates.
