Liquidity Reserve: how to set and calculate it

Calculate each layer of reserve, count only the funding sources that are actually available, and stress test them using an example developer group with 3 projects

Key takeaways

  • The Liquidity Reserve should be calculated from the actual obligations in each layer and compared with the funding sources that are actually available, rather than being set as a single lump sum
  • Restricted customer money and uncommitted facilities should not be counted as reserves
  • In the example, the group passes the normal-case test at 1.13x, but in the stress case coverage falls to 0.77x, so the response plan must be prepared before an event occurs

How many layers to set aside

TierLevelExample formulaUsed for
Working Capital BufferProjectAverage monthly construction cost × 1 monthWaiting for drawdowns and paying contractors
DSRAProjectMonthly debt service × 3–6 monthsInterest and principal only
Cost ContingencyProjectCost-to-Complete × 5–10%Cost overruns
Corporate BufferGroupCorporate overhead × 3 monthsOffice expenses
Group EmergencyGroupTotal annual revenue × 1%Cross-project crisis events

Coverage = countable liquidity sources ÷ required Liquidity Reserve

Example: a developer group with 3 projects

How to count funding sources

Source of fundsCounted?THB million
DSRA already set asideCounts towards the DSRA layer60
Corporate cashCounts45
Unrestricted project cashCounts38
Undrawn Committed FacilityCounts, if the drawdown conditions are still met80
Uncommitted line of THB 50 millionDoes not count; the bank has the right to refuse drawdown0
Restricted customer deposits of THB 90 millionDoes not count0
Countable sources223

Coverage = 223 ÷ 198 = 1.13x and headroom = THB 25 million

Stress test before calling it sufficient

Assumes 6 months, a 10% increase in construction cost and a 30% fall in sales receipts from a base of THB 20 million per month

ItemTHB million
Cost increase 58 × 10% × 634.8
Receipts decrease 20 × 30% × 636.0
Cash lost70.8
Sources after stress 223 − 70.8152.2
Coverage after stress (152.2 ÷ 198)0.77x
Shortfall against required reserve level45.8

A plan should be in place before this point is reached, for example expanding the committed facility, deferring non-essential spending, accelerating collections, calling additional equity or slowing new projects

Cash Flow at Risk

CFaR at confidence level = Expected CF − (Z × σ)

Expected quarterly cash flow of THB 180 million and a standard deviation of THB 45 million (example)

LevelCalculationCFaR (THB million)Below expected value (THB million)
95% (Z = 1.645)180 − 1.645 × 45106.074.0
99% (Z = 2.326)180 − 2.326 × 4575.3104.7

THB 106 million means there is roughly a 5% chance that cash flow will fall below this level. It does not mean a reserve of THB 106 million is needed. The size of the reserve should be based on the amount by which cash flow falls short of the obligations that must be paid. This formula assumes a normal distribution, which project cash flows may not follow, so it should be used alongside scenarios

Contingency Funding Plan

Set the order of funding sources before an event occurs, and check the conditions in the loan and JV agreements as well

  1. Existing reserves
  2. Undrawn Committed Facility
  3. Additional uncommitted facilities
  4. Shareholder loans
  5. Sale of non-core assets
  6. Bridge Loan
  7. Emergency equity injection
Early warning (example)Criteria
Cash Ratio<0.3
Current Ratio<1.0
DSCR Forecast<1.10x
Sales velocity vs plan<50%
Cancellation Rate>15%
Cost Overrun>10%
Days Cash on Hand<30 days

Reserve accounts and short-term investments

Separate accounts by purpose and define who can withdraw and when. For example, the DSRA is used only for debt payments, while investment of other reserves is limited to instruments that can be withdrawn when needed: call deposits, treasury bills and money market funds. Spread counterparties, match maturities to payment obligations and prohibit speculative investment. Return is secondary to the safety of principal

An undrawn committed facility should have a tenor covering at least 6–12 months, be spread across banks and be renewed before maturity

Comparison with a hotel group

The same structure applies to a hold business, but the obligations change: construction contingency becomes a reserve for maintenance and refurbishment. In the example of 5 hotels, the buffer is set at 2 months, the DSRA at 6 months, the MRA at 4% and the CapEx reserve at 2% of revenue, while the group reserve is 1% of total revenue

Adding the group reserve of THB 7.07 million gives a total of THB 146.39 million, equal to 20.7% of total revenue. Figures are illustrative
