Positive contributions to the HIT's performance relative to the Barclays Aggregate included:

●

The portfolio's ongoing yield advantage over the Barclays Aggregate.

●

Performance by corporate bonds, the worst performing major sector in the Barclays Aggregate, posting an excess return of -45 basis points (bps). The HIT does not invest in corporate bonds, whereas the sector comprised 25.1% of the index as of May 31, 2018.

●

Performance by agency fixed-rate single family mortgage-backed securities (RMBS), the second worst performing major sector in the index, with an excess return of -5 bps. The HIT was underweight to this sector with a 17.5% allocation versus 28.1% in the Barclays Aggregate at the end of May.

●

The portfolio's overweight to the highest credit quality sector of the investment grade universe, whose excess returns were the highest among the four credit ratings buckets (AAA, AA, A, and BBB) of the Barclays Aggregate. Those returns were -2, -13, -39, and -64 bps, respectively. Over 96% of the HIT portfolio was AAA-rated or carried a government or government-sponsored enterprise guarantee, compared to less than 72% for the Barclays Aggregate at the end of May.

Negative impacts to the HIT’s relative performance included:

●

Performance by agency multifamily mortgage-backed securities (MBS) in the HIT's portfolio as spreads to Treasuries widened. FHA/Ginnie Mae permanent and construction/permanent loan certificates widened by 7 and 9 bps, respectively. Longer maturity Fannie Mae DUS securities also widened, with the benchmark 10/9.5 structure spread increasing by approximately 14 bps. The HIT had 15.1% of its portfolio invested in Ginnie Mae permanent and construction/permanent loan certificates and 29.4% in single-asset DUS securities of various structures at the end of May, while there were no such securities in the Barclays Aggregate.

May 2018 Performance Commentary

●

The portfolio's slightly short relative duration as Treasury rates fell across the curve. Two-, 5-, 7-, 10- and 30-year rates declined by 6, 10, 11, 10 and 10 bps, respectively.

●

The portfolio's overweight to spread-based assets as swap spreads widened across most maturities. Two-, 5- 7- and 10-year spreads increased by 1, 2, 2.5, and 2 bps, respectively. At the end of May, 95.6% of the HIT's portfolio was invested in spread based assets (4.4% in cash/cash equivalents and Treasuries) compared to 62.4% spread assets in the Barclays Aggregate (37.6% in Treasuries).
