An availability period in a loan agreement is the window during which the lender is contractually obligated to fund your drawdown requests under a committed facility. Once that window closes, any money you have not drawn is gone, and the lender owes you nothing further. These periods appear most often in revolving credit facilities, delayed-draw term loans, and construction loans, and the rules differ across each. Missing a deadline, tripping a condition, or ignoring the fees on undrawn amounts can cost real money.
How the Window Works Across Facility Types
The core idea is constant: the lender commits a maximum amount, and you draw against it over time rather than taking a single lump sum. The specifics change with the product.
On a revolving credit facility, you borrow, repay, and borrow again throughout the availability period, up to the committed limit. The period typically runs for the full term of the facility, and unused capacity refreshes as you pay down outstanding balances.
On a delayed-draw term loan, you draw funds in one or more installments during the availability window, but repaid amounts cannot be re-borrowed. The window is usually shorter, often 12 to 24 months, and any undrawn commitment expires permanently when it closes.
On a construction loan, draws are tied to construction milestones rather than general business needs. The lender releases funds as work progresses, typically after an independent inspection confirms the improvements match the request. The availability period tracks the expected construction timeline.
The distinction between revolving and non-revolving availability matters more than borrowers often realize. On a delayed-draw term loan, unused commitment disappears at expiration. On a revolver, unused capacity stays available until the facility’s maturity date. Confusing the two can leave you short of capital at the wrong moment.
When the Period Starts and How Long It Runs
The availability period begins on the effective date, which is the date all conditions to closing have been satisfied and the credit agreement becomes binding. That is not always the day you signed the documents. If the agreement requires deliverables before it takes effect, such as legal opinions, insurance certificates, or organizational documents, the effective date shifts until those items are in hand.
Duration is negotiated. For corporate credit facilities, revolving commitments commonly run three to five years. Delayed-draw term loans carry tighter draw periods, often 12 to 24 months from closing. Construction loans peg the period to the expected build schedule, sometimes with built-in extensions for permitted delays.
Certain events can shorten or suspend the window before its scheduled expiration. If you fail to deliver a required permit by a contractual deadline, the lender may have the right to delay or reduce the commitment. Financial performance triggers matter too. Most credit agreements require you to stay within specified financial ratios, typically tested quarterly or semiannually, and a covenant breach can freeze your ability to draw even if the calendar says the period is still open.
Conditions You Must Satisfy Before Each Draw
Signing the credit agreement gets you a commitment, not automatic access to cash. Every individual drawdown requires you to satisfy a set of conditions precedent, and lenders take these seriously. Missing one can delay or block funding.
The typical conditions include:
- No default exists under the credit agreement, and the requested draw won’t create one. This certification is usually embedded in the borrowing request itself as a deemed representation.
- Bring-down of representations. Every representation and warranty made at closing, including the accuracy of financial statements, the validity of your corporate existence, and the absence of material litigation, must remain true at the time of each draw.
- Financial covenant compliance. You need to demonstrate that you still meet the credit agreement’s financial covenants, whether that means a leverage ratio, an interest coverage ratio, a minimum liquidity threshold, or some combination. Some agreements require a compliance certificate signed by a company officer with each draw request.
- No material adverse change. Most agreements include a condition that no event has occurred since closing that would materially and adversely affect your ability to repay. This is the lender’s catch-all against deterioration that doesn’t fit a defined covenant.
These conditions apply at every draw, not only the first one. A borrower who was in perfect compliance six months ago but has since tripped a covenant or disclosed a major lawsuit will find the funding window effectively closed even though the availability period has not expired.
How to Request a Drawdown
Drawing funds requires a formal written notice, often called a Notice of Borrowing or Borrowing Request, delivered to the lender or administrative agent. The credit agreement includes a form of this notice as an exhibit, and lenders expect you to follow it closely.
A typical borrowing request must specify:
- The requested amount, which must fall within any minimum draw increments and maximum amounts set by the agreement. Minimum draw sizes of $1 million to $5 million are common in larger facilities; smaller facilities scale down accordingly.
- The proposed funding date. You choose when you want the money, but you must give advance notice. Base rate loans tied to the prime rate may allow same-day notice, while SOFR-based loans typically require at least three business days.
- The interest rate election. If the facility offers a choice between base rate and SOFR-based pricing, you specify which one applies to this draw and, for SOFR loans, the interest period length.
- Wire instructions for the account where funds should be deposited.
Once submitted, the borrowing request is usually irrevocable. The lender’s internal team reviews the notice against the credit agreement’s terms, confirms that conditions precedent are satisfied, and authorizes the wire. Sloppy paperwork is the most common cause of delayed funding. If the notice doesn’t match the required form or arrives after the cutoff time in the agreement, the lender can push the funding date.
Fees on the Undrawn Portion
Having a lender hold capital in reserve for you isn’t free. Most credit facilities charge a commitment fee on the unused portion of the facility throughout the availability period. This fee compensates the lender for tying up balance sheet capacity that it could otherwise deploy elsewhere. Rates vary, but commitment fees of 0.25 to 0.50 percent annually on the undrawn balance are common for investment-grade borrowers, with higher rates for weaker credits.
Delayed-draw term loans often add a ticking fee. Where a commitment fee runs from closing, ticking fees typically start after a short grace period, often 30 to 60 days, and increase the longer the commitment sits undrawn. The purpose is to push the borrower to draw funds or cancel the commitment rather than let it linger. On a large facility, these fees add up quickly and deserve attention during the initial negotiation.
Both commitment fees and ticking fees stop accruing when the availability period ends, whether through expiration, full utilization, or voluntary reduction of the commitment.
Events That Suspend or End the Window Early
An availability period on the calendar does not guarantee access to funds. If an event of default occurs, the lender can refuse to honor further drawdown requests, even if unused commitment remains and the period has not expired. This is one of the most powerful remedies in a credit agreement, and lenders do not hesitate to invoke it.
Typical events of default include failure to make a required payment, breach of a financial covenant, material misrepresentation in the loan documents, bankruptcy or insolvency of the borrower, and cross-defaults triggered by a default under other debt agreements. Some agreements also include a material adverse change default, which gives the lender broader discretion to halt funding when the borrower’s financial condition deteriorates significantly even without a specific covenant breach.
The practical takeaway is that monitoring your own covenant compliance throughout the availability period is not optional. If you spot a potential breach early, you have time to request a waiver or amendment before you actually need to draw. Discovering a default on the day you submit a borrowing request rarely ends well.
Extending or Reducing the Commitment
Many credit agreements include a mechanism for the borrower to request an extension of the availability period, but these provisions are not automatic. Extensions require lender consent, and that consent is often at the lender’s sole discretion.
The process typically requires written notice delivered 30 to 90 days before the current availability period expires. You’ll need to show that no default exists, all representations remain accurate, and all accrued fees and expenses have been paid. Most agreements charge an extension fee, commonly around 0.25 percent of the commitment amount. If the facility involves multiple lenders, each may need to agree individually, and a lender that declines becomes a non-extending lender whose commitment terminates on the original expiration date.
If an extension isn’t available or isn’t granted, the alternative is refinancing before the period expires. Starting that process early gives you room to negotiate. Waiting until the last month puts you in the weakest possible bargaining position.
Reduction runs the other direction. Most credit agreements allow you to voluntarily and permanently reduce the unused portion of the commitment, which eliminates commitment fees on the reduced amount going forward. You deliver written notice to the administrative agent, usually one to five business days in advance, specifying the amount of the reduction. Reductions typically must be in round increments, often $1 million or $5 million minimums depending on the facility size. The reduction is permanent. Unlike a revolver where undrawn capacity refreshes, a voluntary commitment reduction cannot be reversed. You are giving up future borrowing capacity in exchange for lower ongoing fees.
That flexibility is valuable when capital needs turn out smaller than originally projected. Carrying unused commitment at 0.25 to 0.50 percent annually might not sound expensive, but on a $100 million facility with $40 million sitting undrawn, that is $100,000 to $200,000 per year for access you aren’t using.
When the Availability Period Ends
Termination happens in one of three ways: the period reaches its scheduled expiration date, the borrower draws the full committed amount, or an event of default triggers early termination. The result is the same in each case. Any undrawn commitment is canceled, the lender’s obligation to fund further requests ceases, and commitment or ticking fees stop accruing.
The lender sends a final statement confirming the total amount drawn and the end of the borrowing window. The loan then transitions from its draw phase into repayment. The amortization schedule begins, and you start making regular principal and interest payments according to the terms set at closing. For construction loans, that transition often converts the loan from an interest-only construction facility to a permanent amortizing mortgage.
One detail catches borrowers off guard: if you expect to need the last portion of your commitment, submit the draw request well before the expiration date. A borrowing request that arrives on the last day but doesn’t meet the advance notice requirement will be rejected, and the lender is under no obligation to extend the window to accommodate it.
