What it means
A syndicated loan is a large loan provided by a group of lenders under one agreement, with one bank acting as agent to handle payments and paperwork. Splitting it into tranches, or slices, lets each slice be tailored to a different type of lender.
The pro rata tranche is aimed at relationship banks that want to provide credit to the borrower and often earn other business, such as cash management. These loans usually amortise, meaning the principal is paid down in scheduled instalments, and they tend to carry a lower interest margin than loans sold to institutional investors.
Pro rata describes how payments are shared. When the borrower repays, each lender in the tranche receives a share equal to its commitment divided by the total, so no lender is repaid ahead of another.
The institutional tranche, often called a term loan B, usually has little or no scheduled repayment before maturity and a higher margin. Investors in it are looking for yield rather than a wider banking relationship.
For the borrower, the mix of tranches balances cost against flexibility. The pro rata tranche is cheaper and flexible, but its repayments use cash, while the institutional tranche leaves more cash in the business but costs more.
Finance teams should read the agreement carefully for conditions such as financial covenants (promises to keep ratios like debt to earnings within agreed limits). The pro rata lenders are often the ones who vote on waivers if the borrower breaches them.
In practice
Real-world examples.
Example
A packaging manufacturer arranges a $300,000,000 loan to fund an acquisition. Three banks provide a $120,000,000 revolving line and a $60,000,000 amortising term loan, while a fund buys the remaining $120,000,000. The first two form the pro rata tranche. The institutional portion carries a higher margin but requires no early repayments.
Example
A retailer draws $15,000,000 on its revolving line to cover seasonal stock. Each bank funds its share in proportion to its commitment. The retailer repays the same way when the stock is sold. The banks track the balance daily and send one combined notice.
Example
A private equity-owned services business breaches a debt covenant after a bad quarter. The banks in the pro rata tranche agree to waive the breach for a fee. They also raise the margin on their loans. The institutional investors are not asked to vote on the waiver.
Formula
Calculation
Lender's share of a payment = payment amount x (lender's commitment / total commitments in the tranche)
Suppose a $200,000,000 pro rata tranche is shared by three banks: Bank A commits $80,000,000, Bank B commits $70,000,000 and Bank C commits $50,000,000.
The borrower makes a scheduled repayment of $20,000,000.
Bank A receives 20,000,000 x (80 / 200) = $8,000,000.
Bank B receives 20,000,000 x (70 / 200) = $7,000,000.
Bank C receives 20,000,000 x (50 / 200) = $5,000,000.
The total is 8,000,000 + 7,000,000 + 5,000,000 = $20,000,000.Case study
Seen in the real world.
Greenline Logistics is an illustrative, fictional company that raised $250,000,000 to buy a rival. It structured the loan as a $100,000,000 pro rata tranche with four banks and a $150,000,000 institutional tranche sold to loan funds.
The treasury director compared the costs. The pro rata tranche carried a margin of 2.5% over the base rate, while the institutional tranche carried 4.0%, so the extra cost on the institutional $150,000,000 was 1.5% x 150,000,000 = $2,250,000 a year compared with the pro rata price.
She accepted the higher cost for the institutional tranche because it required no scheduled repayment for seven years, leaving cash for integration. In this illustrative story the banks in the pro rata tranche were repaid on schedule and shared each repayment in proportion to their commitments.
Watch out
Common mistakes.
- Assuming that pro rata means the lenders get equal amounts, when the shares follow each lender's commitment.
- Focusing only on the interest margin and ignoring scheduled repayments that reduce cash.
- Overlooking that pro rata lenders often hold the voting power on waivers and amendments, which can matter greatly if the company breaches a covenant.
Questions
People also ask.
What is the difference between pro rata and institutional tranches?
The pro rata tranche is held by banks and usually amortises with a lower margin, while the institutional tranche is sold to investors and pays a higher margin with little repayment before maturity.
Why do banks accept lower margins?
They often earn fees from other services such as cash management, foreign exchange and advisory work, and use the loan to build a wider relationship with the borrower.
Does the term mean pro rata share of a venture investment?
In venture and equity funding, pro rata rights are a different idea, giving an investor the right to buy a share of future rounds to keep its ownership percentage.
