SURETY UNDERWRITING

HOW SURETIES EVALUATE CONSTRUCTION CONTRACTORS, WHAT THE UNDERWRITER IS ACTUALLY LOOKING AT.

QUICK ANSWER

Most contractors think bonding capacity comes from revenue and years in business. Underwriters think in three categories: character, meaning a completion history without disputes, capacity, meaning the technical and operational ability to execute, and capital, meaning the financial position to absorb a loss. Capital is where most bonding problems live, and capital gets read off the financial statements and the WIP rather than off revenue. A contractor who understands how the underwriter reads the file can build the financial infrastructure that moves the capacity ceiling.

The file you submit is the only view of your company the underwriter gets. He isn't walking your yard or watching your crews, so a well run business with sloppy reporting reads as a risk and an average business with clean monthly reporting reads as safe. That's not fair, and it's also cheap to fix. Monthly WIP from closed books, a current balance sheet, and a documented list of finished jobs cost nothing but discipline, and they're the difference between a contractor who gets the limit he asked for and one who gets a counteroffer.

THE DEFINITION

WHAT IT MEANS.

Surety underwriting is an assessment of a contractor's character, capacity, and capital, priced against the risk that a bonded project doesn't get finished.

The underwriter reviews a specific set of documents, and each one tells him a specific story. Current financial statements, meaning income statement, balance sheet, and cash flow statement for the most recent fiscal year. The WIP schedule, showing all active projects with contract value, percent complete, billed to date, earned to date, and projected final cost. Backlog, meaning signed contracts not yet started or still in progress. Reference projects of similar size and type to the bond being requested. A bank letter confirming line of credit availability and the current draw status. An insurance certificate with general liability and workers comp limits and expiration dates.

WIP is the central document in that stack. A surety is underwriting the risk that a project doesn't get completed, and the WIP tells the underwriter how you're managing 8 to 12 projects at the same time right now. A WIP that shows consistent overbilling positions, projects that look profitable the whole way and then produce a loss at closeout, and cost to complete estimates that never move tells him you're managing cash through billing rather than managing projects through financial control. That contractor gets lower limits and worse rates even when the balance sheet looks strong.

THE THREE C'S

CHARACTER, CAPACITY, AND CAPITAL, IN THAT ORDER.

01

Character, read from completion history and references

The first question is whether this contractor has a history of finishing projects without disputes, claims, or defaults. It gets assessed from your completion history and from the people who will vouch for it. Character doesn't have to be perfect to underwrite well, but it does have to be documented, because an underwriter can't give you credit for a clean record he can't see.

02

Capacity, read from project history and the equipment list

The second question is whether you have the technical ability, the crew, the equipment, and the management to execute the size and type of project being bonded. It gets assessed from your project history and your equipment list. A contractor asking to be bonded well above anything he has completed before is a capacity question before it's ever a money question.

03

Capital, read from the financial statements and the WIP

The third question is whether you have the working capital, net worth, and debt structure to fund the project through completion if something goes wrong. It gets assessed from the financial statements and the WIP. Most bonding problems are capital problems, which means the financial position doesn't support the limit that was requested, and revenue has almost nothing to do with the answer.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

The statement upgrade math

For an established contractor with a strong relationship, financials produced in house plus tax returns filed by your CPA are often enough for a $2M single project bond. For a new surety relationship or a higher limit, CPA reviewed statements produce faster approvals and more capacity. That upgrade runs $3,000 to $6,000 annually, and it typically pays for itself on the first large project that wouldn't have been bondable at the old limit.

HOW TO IMPROVE YOUR SURETY RELATIONSHIP

WHAT CHANGES THE UNDERWRITING OUTCOME IN YOUR FAVOR.

Submit WIP on a consistent schedule

Monthly, from closed books, by the 15th. Not when the surety asks for it and not once a year at renewal. An underwriter who receives unsolicited monthly WIP from a contractor sees that contractor differently than one he has to chase for it.

Show a clean completion history

Every completed project from the last 3 years with final contract value, completion date, and outcome, meaning on time, under budget, and no disputes. This is the character piece of the file. It doesn't need to be spotless, it needs to be written down.

Present the balance sheet at current value

Not the one from 9 months ago. The balance sheet at the time of the bond application should reflect current AR, current cash, and the current line of credit draw. If you collected AR since the last statement, show it. The underwriter decides on the financial picture in front of him the day he reads the file.

Have your surety agent advocate for you

Your agent is the one presenting the file to the underwriter. An agent who knows your business, understands your capacity, and can answer underwriter questions without calling you first is worth more than a better balance sheet presented by an agent who doesn't know you.

The CFOS documentation package

We produce the financial package sureties want to see, and we produce it on the same cadence every month whether a bond is pending or not. Contractors running on CFOS for 12 months or more have the documentation infrastructure surety underwriters trust, which is most of what separates a strong file from a thin one.

We do the books. No payroll.

Strategic

Every job shows its margin while it's still running.

Everything in Executive, plus the job costing and WIP platform set up, loaded with your cost codes, and managed for you every month. You never have to learn it.

We do the job costing.

COMMON QUESTIONS

FREQUENTLY ASKED.

Sureties charge higher rates to contractors whose WIP suggests higher completion risk: consistent overbilling, losses recognized late, and a methodology that changes from month to month. A contractor with 24 months of consistent, reliable WIP produced from closed books, showing accurate job management, will get better rates and more capacity than one whose WIP goes in once a year and gets built a different way every time.
For established contractors with strong relationships, financials produced in house alongside tax returns filed by a CPA are often sufficient at this level. For a new surety relationship or higher capacity, CPA reviewed statements produce faster approvals and higher limits. The upgrade runs $3,000 to $6,000 annually and is typically recovered on the first large project that wouldn't have been bondable at the prior limit.
Quarterly at a minimum. Send WIP monthly if you're growing your capacity or chasing larger projects. An agent who sees your monthly WIP and watches the business grow is in a position to argue for you at the underwriting table. One who only hears from you at renewal has no context to bring into that conversation.
